If shrinkage porosity, refill wetting agent 2105-3; If there are many bubbles, add defoamer. Control the dosage of each supplement, then disperse at medium speed for 5 minutes, repeat until a good apparent effect is achieved (due to the presence of more bubbles in the freshly stirred product, the coating film allows a small number of bubbles).

It's best to consult the relevant companies for this kind of technical knowledge, after all, they are more professional. It's okay to ask the material supplier when buying materials.

Same content as oily epoxy resin!

The proportion of pigments is different according to the color!

Water-based epoxy floor paintIt is an epoxy resin flooring material that is environmentally friendly and wear-resistant. It has a very high adhesion to the substrate, and the cured coating film has excellent corrosion and chemical resistance, as well as excellent shrinkage, hardness, abrasion resistance and electrical insulation. Water is used as a dispersion medium to save energy and meet the requirements of a pollution-free environment.

So let's introduce the characteristics of water-based epoxy resin floor paint.

1. Characteristics of water-based epoxy resin floor paint.

1.First of all, epoxy resin is a thermoplastic linear structure and is a very good material. When heated, the solid becomes liquid, and its high viscosity decreases.

It is only useful when used in combination with a hardener (a pure one-component water-based epoxy system requires the addition of a potential hardener). Therefore, the aqueous epoxy system must contain a waterborne epoxy resin and a waterborne epoxy curing agent, and three different water dispersion paths can form three forms of water dispersion.

2.Secondly, the aqueous epoxy system has more options (there are theoretically nine combinations), which is also known to us, but also increases the difficulty of selection. At the same time, in the actual application process, by adding a large number of pigments, fillers, additives, etc., the application performance of the waterborne epoxy system is improved at the same time, and the shortcomings or serious defects, uncertainty and complexity of the waterborne epoxy system are also covered.

3.Again, to avoid complexity and simplicity, pay attention to the form of water-based epoxy resins and water-based epoxy curing agents. By controlling the performance of waterborne epoxy resins and evaluating waterborne epoxy resins, you can build a strong foundation for tall buildings so that you can choose a faster and better waterborne epoxy system.

Second, the type of floor paint.

1.More common water-based epoxy resin system: low molecular weight liquid epoxy resin (epoxy equivalent of about 190) and water-based epoxy curing agent, the excellent material oxy resin composed of the system ring is generally not pre-emulsified, and is mixed with water oxygen curing agent before emulsification, which can be well dispersed or dissolved in water, and has excellent emulsification effect on low molecular weight liquid epoxy resin.

The hardness increases dramatically.

2.Good structure type waterborne epoxy resin system: it is composed of high molecular weight solid epoxy resin emulsion and waterborne epoxy curing agent, and due to the low reactivity of polymer weight epoxy resin, the molecular weight epoxy resin is small, the application cycle of type II waterborne epoxy resin system is shorter than it is longer than type I, and the surface drying time is shorter than that of type I.

3.Good effect type waterborne epoxy resin system: a new type of anti-cavitator epoxy resin emulsifier composed of low molecular weight liquid epoxy resin emulsion and water-based epoxy curing agent, including surface-active segments (hydrophilic segments) and epoxy resin segments.

Lipophilic segments) greatly improve the compatibility of emulsifiers and epoxy resins, while providing a constant reinforcement effect on the coating film. Closed minds.

The characteristics of water-based epoxy resin floor paint and the types of floor paint are introduced in detail in this article. It is recommended that when you choose floor paint, you should choose some materials with better materials, no harmful gases, and low formaldehyde and benzene content. If.

Nowadays, there are many decoration materials, which bring convenience to our lives. Let's have good results when we use it. For our decoration materials, floor paint, we don't know much.

This is not good for our decoration. Let's take a look at it with usWater-based epoxy floor paintWhat are the features? In this way, it will be very smooth when we are building.

1. Characteristics of water-based epoxy resin floor paint.

1. First of all, epoxy resin itself is a thermoplastic linear structure, which is a good material. After heating, the solid state becomes liquid, and the high viscosity becomes low viscosity, which is only practical when used in combination with a curing agent (a latent curing agent is also added to a pure one-component aqueous epoxy system). Therefore, the waterborne epoxy system should include water-based epoxy resin and water-based epoxy curing agent, and three water-dispersion forms can be formed by different water-based pathways.

2. Secondly, the aqueous epoxy system has more choice combinations (theoretically there are 9 morphological combinations), which is also our understanding, but it also increases the difficulty of selection. At the same time, in the actual application process, by adding a large number of pigments, fillers, additives, etc., the application performance of the waterborne epoxy system is improved, and the deficiencies and even serious defects, uncertainties and complexities of the waterborne epoxy system are also covered.

3. Also, abandon the complicated and simplify, pay attention to the form of water-based epoxy resin and the form of water-based epoxy curing agent at the same time, and understand it. By controlling the essence of the waterborne epoxy and the evaluation of the waterborne epoxy, we can achieve a faster and better selection of the waterborne epoxy system, and lay a solid foundation for your high-rise building!

Second, what are the kinds of floor paint?

1. The more common water-based epoxy resin system: a good material, composed of a low molecular weight liquid epoxy resin (epoxy equivalent of about 190) and a water-based epoxy curing agent, the epoxy resin in this type of system is generally not emulsified in advance, but mixed and emulsified by the water-based epoxy curing agent before use, which can be well dispersed or dissolved in water, so as to have a good emulsification effect on the low molecular weight liquid epoxy resin, and the hardness of the coating film grows rapidly;

2. Very good construction of water-based epoxy resin system: worthy of everyone's choice. It is composed of a high molecular weight solid epoxy resin emulsion and a water-based epoxy curing agent, because the reactivity of the high molecular weight epoxy resin is low and the molecular weight epoxy resin is small, so the application life of the water-based epoxy resin system is relatively long, and the surface drying time is shorter.

3. Good water-based epoxy resin system: everyone likes it. Composed of a low molecular weight liquid epoxy resin emulsion and a water-based epoxy curing agent, the new reactive epoxy resin emulsifier contains both surface-active segments (hydrophilic segments) and epoxy resin segments (lipophilic segments), which greatly improves the compatibility between the emulsifier and epoxy resin, and at the same time has a certain toughening effect on the coating film.

The above content is to introduce the characteristics of water-based epoxy resin floor paint. This helps us in our choices and allows us to make better use of the material.

You can use solvent-free epoxy floor paint or water-based epoxy floor paint, water-based epoxy floor paint is tasteless, diluted with water. Thinners play an important role in epoxy floor paints. Epoxy resin diluent is mixed with base resin, which not only does not reduce the cross-linking density of epoxy resin, does not reduce the hardness after curing, but also can reduce the viscosity of the curing system, increase fluidity, prolong the service life of epoxy resin floor paint, and facilitate large-area construction; It improves the operability of the floor paint without affecting the basic properties of the cured object.

It is convenient for casting, pouring, bonding, sealing, impregnation, etc.

It has the following five advantages.

1. Excellent environmental performance.

Waterborne epoxy floor paints do not contain organic solvents or volatile organic compounds and do not cause air pollution, thus meeting the current requirements of environmental protection.

2. Truly water-based.

Water-based epoxy floor coating, just from the literal understanding, we know that it is a kind of water as a dispersion medium, odorless, non-combustible, storage, transportation and use of the safety is also greatly improved.

3. Strong applicability.

It has extremely high adhesion to many substrates, excellent corrosion resistance and chemical resistance of the cured coating film, and small shrinkage of the coating film, high hardness, good wear resistance, excellent electrical insulation performance, etc.

4. Good operation performance.

The construction operation performance of water-based epoxy resin coating is good, the construction tools can be directly cleaned with water, engraved in room temperature and humid environment for curing, there is a reasonable curing time, and the high cross-linking density is guaranteed. This is incomparable to the usual water-based acrylic floor paint and water-based polyurethane floor paint.

5. Good compatibility.

The compatibility between epoxy curing agent and epoxy resin is conducive to the stability of the system after dispersion of water-based epoxy resin emulsion, and the better the compatibility between the two, the easier it is for the epoxy curing agent to diffuse to the inside of the epoxy resin particles, which is conducive to the curing reaction.

Problems with water-based epoxy floor paint:

1. Generally speaking, the best of water-based epoxy floor paint is relatively chaotic, but brand paint still has a competitive advantage.

2. Generally, it can be used for 3-5 years, which is shorter than the 20-year service life of water-based polyurethane mortar floor.

3. Because it is not resistant to ultraviolet rays, it is generally used indoors, while water-based polyurethane floor paint can be used outdoors.

4. Due to the poor low temperature resistance, it cannot be used in cold storage and other low temperature environments.

5. It begins to soften under the high temperature steam of about 70, and it is not recommended to use it in a high temperature and high humidity environment.

6. It is suitable for a small range of ground environment, and the material is relatively brittle, so it is only suitable for concrete foundation, otherwise it is easy to have faults and cracks.

7. The curing time is long, and the temperature and humidity are strict. The construction temperature is 5 -30 .

8. The noise reduction effect is poor and the elasticity is low.

9. The workshop environment has poor tolerance and compressive load, which will reduce the use effect and service life.

10. The construction process is simple, and the preset expansion joints are of little significance, and they are limited by the material performance, especially the primer coating effect is not good.

The coating film has small shrinkage, high hardness, good wear resistance, and excellent electrical insulation performance.

Epoxy water-based floor paint: water is mixed with water-based curing agent as a dispersion medium, with low odor, non-combustible, safe and environmentally friendly, very safe in transportation, storage and use, pollution-free, in line with environmental protection requirements, low requirements for construction ground, and can be used in a humid environment. It has good permeability, not easy to bubble, not peeling, not easy to crack and other properties are very good.

Water-based epoxy flooring made of water-based curing agent has the advantage of cost-saving convenience in terms of cost performance, especially in thick coating.

Oily floor paint: contains a large number of organic solvents, compared with water-based floor paint, the pollution to the environment is more serious, and the safety factor in the production, transportation and use process is relatively low, there are potential safety hazards of ignition and explosion, and the water barrier needs to be laid in the construction, otherwise the construction and use in the humid environment will cause blistering, delamination and other problems, so the oily floor paint can only be constructed and used in a dry environment!

Epoxy floor paint has good oiliness hardness and wear-resistant. The hardness of water-based epoxy floor paint is not very good, but it is environmentally friendly and has no volatile gases.
