What is the main content of latex paint? Why?

It mainly includes emulsions, pigments, fillers, and additives.

Latex. Emulsion is the most important raw material affecting the performance of latex paint, which looks like milk, and is made of some petrochemical raw materials such as vinyl acetate, acrylate, styrene, etc. through polymerization chemical reaction in water. Depending on the raw materials and processes used, the resulting emulsion has different properties.

The main functions of emulsion are adhesion, water resistance, alkali resistance, anti-photoaging, etc. Some inferior coatings will not use the above-mentioned emulsions, but use polyvinyl alcohol, polyvinyl alcohol formaldehyde as raw materials, and even starch and other things as binders, especially polyvinyl alcohol formaldehyde, which does not synthesize well and contains a large amount of free formaldehyde, which will bring damage.

Pigment. Since most latex paints are white or light colors based on white, the use of titanium dioxide or lithopone (zinc barium white) two white pigments is harmless to the human body, and most color pigments are also harmless to the human body.

Fillers. The filler plays a filling role and is a substance that must be contained in latex paint. It can enrich the paint film, increase the hiding power, and some also give the latex paint less sedimentation and good brushability.

Commonly used fillers are calcium carbonate, talc, kaolin, barium sulfate, wollastonite powder, etc., which are natural mineral raw materials and are harmless to the human body.

Additives. Modulator: to prevent latex paint from settling during storage, and not to fall when painting vertical surfaces, cellulose ethers are commonly used.

Film-forming additives: In order to dry the latex paint film and prolong the construction season in the case of low temperature, polyols and their derivatives are often used.

Fungicide: In the process of storage or film formation, latex paint is polluted by ubiquitous microorganisms, coupled with suitable temperature and humidity, it is easy to make the paint in the paint barrel corrupt, demulsification and foul odor, paint film breeds mold, black and falls off. Manufacturers generally add some fungicides to prevent the growth of microorganisms.

Emulsion PaintLatex paint, also known as synthetic resin emulsion coating, is a kind of organic paint, which is made of synthetic resin emulsion.

It is a kind of water-based coating prepared by adding liquid as the base material and adding pigments, fillers and various additives. Depending on the raw materials used for production, latex paint is mainly.

There are polyvinyl acetate latex paint, ethylene propylene latex paint, pure acrylic latex paint, styrene acrylic latex paint and other varieties; It is not based on the product applicable environment.

Same, divided into interior wall latex paint and exterior wall latex paint; According to the glossy effect of the decoration, it can be divided into matte, matte, semi-gloss, mercerized and.

There are types such as light.

Supplement: Coatings are divided into three categories: inorganic coatings, organic coatings and organic and inorganic composite coatings. Among them, organic coatings are divided into solvents.

type, water-soluble and latex coatings: paint is a common name for oil-based coatings, with organic solvents as the dispersion medium; Water-based paints are divided by water.

Bulk media. According to the different dispersion methods, water-based coatings can be divided into two types: water-soluble and water-dispersible. Latex paint is a water-dispersible coating.

It is a coating made of synthetic resin emulsion as the base material, and the filler is refined by adding various additives after grinding and dispersing lead. According to the characteristics and.

The scope of application of latex paint is divided into interior wall latex paint, exterior wall latex paint, other special paints, etc.

Everyone also knows that latex paint is also a kind of chemical product, and everyone who is involved with these chemical products will want to know what are its main components? Is it harmful to our body? You have these concerns, you can understand, today is to solve your concerns for you, here to introduce the main components of latex paint and how should we identify latex paint?

The main ingredient of latex paint.

1. As the name suggests, the base material is the basic raw material, which is generally a variety of organic synthetic resins, but also inorganic raw materials. The products produced by our company are mainly made of water-based synthetic resin, generally known as polymer emulsion, which is used as the base material of latex paint, also known as the main film-forming substance.

2. Pigments include color pigments, white pigments, and institutional pigments. Coloring pigments are divided into organic and inorganic pigments, and white pigments are represented by titanium dioxide, which is an inorganic pigment. Institutional pigments generally play a filling role in paints, but do not color and mask.

3. Solvent water-based coatings are represented by latex paint, and water is used as a diluent.

Fourth, additives to improve the appearance, storage and internal properties of the coating, the amount of addition is generally relatively small, but the effect is obvious. Commonly used additives are: thickeners, dispersants, rheology additives, defoamers, anti-settling agents, etc.

How to distinguish latex paint.

1. Look. Real latex paint looks more oily and shiny, and a thin layer of latex similar to engine oil floats on the open barrel. About a millimeter. Fake latex paint will vote for a thin layer of water. And the lacquer has a blue head.

2. Smell. Real latex paint has a faint fragrance with an earthy smell. Fake latex paint has a heavy earthy smell and is pungent, or there is no smell at all.

3. Wipe. Latex paint.

The real latex paint is particularly delicate and lubricated. The fake latex paint is astringent and grainy.

Fourth, brush. Real latex paint is smooth to brush and has great coverage. The fake one has no hiding power, and it doesn't have much hardness after drying.

Fifth, pull. Take a small stick and stick it with latex paint, which can hang a long silk and continue to fall evenly.

Sixth, the test. Rub with finger sticky latex paint, no rough feeling of grit, and there is a slippery feeling when rinsed with water.

Latex paint, also known as synthetic resin emulsion coating, is a kind of organic coating, which is a kind of water-based coating prepared by adding pigments, fillers and various additives to synthetic resin emulsion as the base material. According to the different raw materials for the production of Wuhui, latex paint mainly includes polyvinyl acetate latex paint, ethylene propylene latex paint, pure acrylic latex paint, styrene acrylic latex paint and other varieties. Ladies and gentlemen, do you have a deeper understanding of latex paint after seeing the introduction?

The introduction of latex paint components and the method of identification will be of great help to you when choosing latex paint, of course, you should also compare each other when choosing latex paint, so as to choose a good latex paint.

The emulsion content of latex paint does not affect the whiteness of latex paint, and does not affect the emulsion in the 5-40% latex paint to increase the strength of the coating, improve the scrubbing resistance of the coating film, and at the same time, when the paint is used for exterior walls, the increase in the amount of emulsion can also improve the aging strength of the coating, and increase the function of the service life of the coating. The amount of emulsion in latex paint is generally between 5-40%, and the better the quality of the coating, the higher the emulsion content As for the pure propylene you are looking for, silicon propylene acrylic, styrene acrylic and other emulsions, it is recommended to go to the professional coating trembling tan to change the raw materials. Hope it helps.

Latex paint is composed of emulsion, pigment, filler, additives, fungicide and water, and to judge whether latex paint is toxic, mainly to see whether the raw materials it adds contain toxic ingredients.

Some inferior architectural coatings, although they are known as latex paints, do not use the above-mentioned emulsions at all, but use polyvinyl alcohol, polyethylene lead and other chemical raw materials such as formaldehyde, and even starch and other things as binders, especially polyvinyl formaldehyde, often because the synthesis process is not up to standard, containing a large amount of free formaldehyde, which will bring damage.

In the process of storage, or after drying and forming a film, the latex paint is polluted by the microorganisms that exist everywhere, coupled with the appropriate temperature and humidity, it is easy to make the paint in the paint barrel corrupt, break the emulsion and produce a foul smell, and the paint film breeds mold, blackens and falls off.

In order to prevent the breeding of microorganisms, manufacturers should add some fungicides, there are many varieties to choose from, as long as the selection is appropriate, the number of additives is correct, it will not cause harm to the human body. However, it is not excluded that a small number of manufacturers may add mercury salts as fungicides in order to reduce costs.

Decoration paint has a somewhat strong or light smell, and some paint smells even so strong that it is easy to make people feel uncomfortable. Now more and more people choose latex paint to powder refresh the home, so is latex paint toxic? Latex paint material parametersWhat is it?

Next, we will introduce to you the material parameters of latex paint and whether there is any poison related content, I hope this article can bring you some help and reference, let's take a look at it!

Is latex paint toxic

Latex paint is a water-based decoration coating, which belongs to green decoration products.

The film performance of latex paint is better than that of solvent-based paint, and the organic solvent, which accounts for half of the solvent-based coating, is replaced by a water canopy, so latex paint is basically non-toxic, but this is not absolute. Whether latex paint is toxic or not depends on the harmful substances contained in the specific latex paint.

Latex paint material parameters

Latex paints may contain organic solvents such as formaldehyde, methylene chloride, chloroform, benzene, toluene, or heavy metals such as lead, cadmium, chromium, and mercury. Does latex paint have formaldehydeLatex paint is a binder, and there is naturally formaldehyde in it.

Latex paint is widely used in construction, furniture manufacturing and daily life, and will volatilize phenol, cresol, formaldehyde, acetaldehyde, styrene, ethylbenzene, acetone, diisocyanate, ethylene acetate, epichlorohydrin and other large organic pollutants when used.

Most of the ingredients of latex paint are benzene, but high-quality brand latex paint contains only trace amounts of benzene.

When the latex paint is applied to the surface of the wall, the benzene series in the latex paint becomes particularly volatile, and when the socks are dried by the latex paint, the benzene series will not volatilize, so there will be no harm of excessive benzene.

Benzene-free paints do not exist, and formaldehyde-free latex paints do not exist. But when choosing latex paint, we can choose low-aldehyde latex paint.

Latex paint is a water-based coating, their paint film performance is much better than solvent-based paint, accounting for half of the organic solvent of solvent-based paint is replaced by water here, so the toxicity of organic solvent is basically solved by latex paint.

Latex paint is made of some polymer aqueous solution film-forming substances, in addition to water and safe and harmless different types of polymers or polymers, it also contains a small amount of emulsifier and a trace of unpolymerized free monomer, free monomer is some volatile small molecule substances, there are different degrees of toxicity problems, now the concentration of free monomer in environmental protection paint is controlled below, and the dosage of additives is more than 2% to 3%; The little is only in between. To sum up, as long as it is a composite standard latex paint material parameters, there is no problem, and it can be used with confidence.

The above is the latex paint we bring to you is toxic, the introduction of latex paint material parameters, I hope to bring you some help, I don't know if you are satisfied with the introduction?

Latex paints are generally used for glass and wall mounting. The main components of latex paint are emulsion, pigment, roller filler, and various additives. Latex paint is an organic paint. Emulsion paint uses water as the dispersion medium, and adds pigments, fillers and additives.

According to the different production materials, latex paint mainly includes polyacetate ethylene envy emulsion paint, ethylene propylene emulsion paint, pure acrylic emulsion paint, styrene acrylic emulsion paint and other varieties. Latex paint also has, true and fake, there are foreign imports, there are also domestic, when buying latex paint, we must seriously look at the brand of latex paint but also investigate the real object of latex paint.

Latex paint is one of the most widely used wall decoration materials, and I will share with you his composition and the hazards of cavity. Latex paint, it is a kind of water as the medium, acrylates, styrene-acrylate copolymers, vinyl acetate aqueous solutions of round polymer as film-forming substances, adding a variety of auxiliary components to make, the film-forming material is insoluble in water, the water resistance and weather resistance of the coating film is greatly improved than the first category, no traces are left after wet scrubbing, and there are different decorative types such as flat light and high gloss. Latex paint may still cause harm to the human body, mainly including:

Organic volatiles (VOCs): There are dozens of additives in latex paint, and if these additives are not selected properly, latex paint will release organic volatiles when it dries, and more than a certain concentration will cause harm to the human body. Pigment.

Some improperly selected pigments contain heavy metals such as lead and mercury, which are harmful to human health. It is recommended that you try to choose a large brand latex paint when you buy, preferably with ten ring certification, so that the quality is more guaranteed. I hope mine can help you and have a great day!
