Introduction: Environmental protection coating is a kind of coating whose performance and safety indicators are in line with the national "Technical Requirements for Environmental Labeling Products". Everyone generally chooses environmentally friendly paints for home decoration, because compared with other paints, environmentally friendly paints are non-toxic.
But are eco-friendly paints really non-toxic? In this article, we will answer your questions.
Introduction to eco-friendly coatings
Generally speaking, environmentally friendly coatings are divided into two categories according to volatile organic compounds (VOCs), one is low-VOC coatings and the other is zero-VOC coatings, and the volatiles of VOCs are liquid, while zero-VOC coatings are in powder form. The volatile content of low-VOC paints is below 30g L, while the volatile content of zero-VOC paint is even lower, below 1g L, and it is almost impossible to feel whether it has volatiles or not. It is necessary to produce environmentally friendly coatings with low VOC content, but this is far from enough, and the emulsion of film-forming additives can not have a high residual liquid, and the more residual liquid, the volatile toxic gas content of VOC will also increase.
Environmentally friendly coating performance
Healthy and environmentally friendly coatings not only refer to no pollution, but also have functions that are conducive to the improvement of the environment and human health, such as resisting bacteria, removing odors, purifying the air, adjusting air humidity, etc., such as activated carbon wall materials.
Non-polluting environmentally friendly paint means that the paint composition does not contain carcinogens and toxic chemicals, and will not have adverse effects on human health, pregnancy and genetics. According to national regulations, the formaldehyde content in environmental protection coatings can not be higher than 10mg L, and in the process of making paints, toxic heavy metals such as lead and chromium can not be used as pigments or desiccant.
Are environmentally friendly paints toxic
Although eco-friendly coatings are non-polluting, are eco-friendly coatings also non-toxic? In fact, some volatile agents and solvents must be added to coating products, but these additives often contain some toxic substances, such as some heavy metals and VOCs. As an environmentally friendly coating, must meet the German DIN product standards, although the additives contain less toxic substances, but always contain lead, chromium and other heavy metals, in the short term respiratory paint volatile organic compounds may not have greater harm to the human body, but in the long run, toxic heavy metals and volatile toxic organic compounds have a subtle effect on the human body function to produce a certain amount of harm, therefore, before living in a new house must ventilate the house.

Speaking of coatings, everyone is certainly no stranger, when carrying out home decoration, we are in contact with all the time in the process of purchasing building materials. When it comes to coatings, it is inevitable to think of "toluene, xylene, environmental protection and other synonyms". Brother Dongfan: So do you know which paints are harmful?
Harmful coating 1: ethylene glycol ether and its ester solvent coating.
This kind of coating has a direct killing effect on the human body, as long as people are exposed to it for a long time, the heavy ones will damage the blood and lymph, and the more serious ones will also have great harm to the reproductive system.
Harmful paint 2: It is a paint with amino paint.
If you use this paint to brush the door and window, passers-by can smell it, and sometimes the smoked person will be dizzy, unable to open his eyes, and the harm is obvious.
Harmful paint three: some anti-corrosion coatings.
Sometimes it is required to bring some extra features, such as the paint used by the ship, because it is required to kill seaweed, so some toxic substances have to be added. For example, the addition of heavy metal substances can poison some workers who are close to them for a long time.
Harmful paint four: paint with solvent toluene.
This kind of toxin will not be noticed in the short term, but will be exposed for a long time, and slowly accumulate toxins. As a result, the body is unwell, there is a feeling of being dumb and eating coptis, and when we accumulate more and find the problem, it will be too late.
So many paints are toxic, so which one should we choose! It's a real headache.
What we may be able to do is: 1. Don't pursue too much of the gorgeous vibratory effect. Choose a brand of paint to minimize the harm;
2. Choose a pure natural paint. (EGESE wood wax oil, wood oil, etc.).
Guan Xianhail is introduced to you here for which coatings are harmful to your health, and you should pay attention to identify and avoid them when purchasing coatings. Of course, you have to let go of some styles and embrace new ones. There is still a long way to go for environmentally friendly coatings.

When decorating the walls, a variety of paints are required. Is environmentally friendly paint harmful to the human body? PChouse will take you to find out.
Eco-friendly paint is not absolutely safe, and may bring some harm to different groups of people, it only reduces the content of harmful substances contained in it to a standard. Every country has different standards for environmental protection. China's environmental protection standards are very low, so there will be so many coatings with ultra-high content of harmful substances on the market circulation.
The environmental protection standards of European and American countries are relatively high, so there are fewer harmful coatings circulating on the market. The data shows that the market share of water-based paints in European and American countries is 60%-80%, while the market share of water-based paints in China is less than one percent.
The first layer, the organic volatile amount of environmentally friendly paint: that is, we often say that VOC indicators, organic volatiles are very harmful to human health.
Second, the toxicity of environmentally friendly paint solvents: the harmful substances contained in the paint are directly harmful to the health of the workers who paint the paint.
The third layer, the user's safety issues: the paint contains volatile solvents, and the solvents are basically volatilized during the period of time when the paint is dry. Although the total amount of these solvents is not much, once there are toxic substances in the solvent, then users will also have symptoms of physical discomfort when living in this environment for a long time.
Therefore, the use of toxic solvents must be limited in the manufacture of environmentally friendly paints.
