Abstract: Now the decoration is more and more advocating environmental protection, many owners out of health considerations, spend a higher ** to buy environmental protection paint, but many people think that environmental protection paint is completely non-toxic, harmless and formaldehyde-free, which is actually a misunderstanding, environmental protection paint also contains formaldehyde, and excessive use will still exceed the formaldehyde standard; The environmental protection of environmental protection paint is reflected in its low raw material pollution and strict environmental protection index requirements, including VOC content, formaldehyde content, etc. After brushing the environmental protection paint, it is recommended to open the window for ventilation for 1-2 months, and you can move in after passing the test. Let's take a look at the detailed introduction.
Does eco-friendly paint have formaldehyde?
The answer is yes, environmental protection paint more or less contains formaldehyde, as a binder, as long as it is used in construction, furniture manufacturing and daily life, it can volatilize a large number of organic pollutants when used, the main types are: phenol, cresol, formaldehyde, acetaldehyde, styrene, ethylbenzene, acetone, diisocyanate, ethylene acetate, epichlorohydrin and other harmful substances. It is impossible to have a completely environmentally friendly paint, because its composition contains benzene, formaldehyde and other substances, the definition of environmental protection paint is that the content of formaldehyde, benzene and other materials is lower than that of general paint, and the harm to the human body is relatively small, so it is called environmental protection paint, but due to the cumulative effect of indoor space, if the amount of environmental protection paint is used too much, there can also be pollution, and formaldehyde may also exceed the standard.
What is the environmental protection of environmental protection paint?
1. The raw material pollution of the environmentally friendly coating itself is low, and it does not contain toxic substances, carcinogens and substances that have adverse effects on human health and genetics.
2. The standard of environmental protection paint requires that formaldehyde shall not exceed 10mg l, and lead, chromium, and related materials shall not be used as pigments or desiccants in the paint production process.
3. The product quality indicators of natural diatom mud environmental protection coating must meet the German DIN standard.
4. Environmental protection tests will be carried out on environmental protection paint before leaving the factory, including short-term test of aquatic biology, short-term test of fish, 21-day aquatic biological test, long-term test of aquatic biology, and packaging test.
How long can eco-friendly paint be occupied.
How long does it take for eco-friendly paint to live in people? It is recommended that the windows should be opened for ventilation for one or two months after the decoration of the new house, and then the air test should be carried out, and the doors and windows should be closed for about an hour before the test.
Environmental protection paint environmental protection indicators.
1. VOC content.
Now the country is implementing a mandatory implementation standard, that is, VOC 120G L. There are three types of VOC effects on the human body: odor and sensory effects; pathologies due to mucosal irritation and other systemic toxicities; Certain volatile organic compounds have been shown to be carcinogens or suspected carcinogens.
2. Formaldehyde content.
At present, the country implements a mandatory standard value of 100mg kg. Formaldehyde itself is highly toxic, has a strong coagulation effect on proteins, can combine with the amino and hydroxyl groups of nucleic acids to denature, can hinder the action of gastric enzymes and pancreatic enzymes, thus affecting metabolic function, and its vapor has a carcinogenic effect on rodents.
3. Heavy metal content.
Heavy metals mainly refer to soluble lead, cadmium, chromium, mercury and other substances, some heavy metals are essential trace elements for the human body in a certain concentration, but the amount of entering the human body exceeds the limit that the human body can tolerate, it can cause serious physiological damage and cause a variety of diseases. Lead poisoning is more severe in children, who have a special susceptibility to lead. CFR 1303 defines lead content greater than 60mg kg as lead paint, which is prohibited for use in public places or interior decoration.
Does eco-friendly paint have an impact on children?
We all know that many families are willing to buy environmentally friendly paint, because everyone buys it for the environmentally friendly and non-toxic effect of environmental protection paint. Especially for some families with children at home, in order to let their children grow up healthy and happy in an environmentally friendly and non-toxic environment, does the environmentally friendly and non-toxic environmental protection paint mentioned in the manual have an impact on children?
Eco-friendly paint does not mean that it is completely non-toxic and harmless, and excessive indoor use will also produce harmful substances, which will bring certain harm to children's health. Therefore, it is recommended that when consumers buy environmentally friendly paint, they need to go to the regular store to buy the environmental protection paint produced by the regular manufacturer, especially pay attention to the fact that the product must have the batch and batch number approved by the state, and do not believe the seller's various test reports, because, China is currently implementing the inspection system rather than the sampling system, and the test report provided by the merchant at most shows that the samples sent to the testing agency at that time meet the relevant standards, and not the same products sold on the market can meet the same standards, and consumers still choose carefully.
