In the mid-1990s. China has published GB 5020794 national standards for "Technical Specifications for Roof Engineering", and has made clear provisions on the quality requirements, construction methods, and engineering acceptance of different types of waterproof coatings. This has played a positive role in the development of waterproof coatings for buildings.
However, there is no mandatory standard for waterproof coatings and the market is confusing. It needs to be further regulated.
In the decoration of kitchens and hygiene, waterproofing is a necessary procedure, and in the ten compulsory national standards, there is no provision for restrictive standards of harmful substances for waterproof coatings. Therefore, it is necessary to further strengthen management in home decoration.
Some home renovations found that the odor in the bathroom and the kitchen was relatively large. After testing at the testing center, it was found that it was mainly due to the pollution caused by the waterproof paint, and the pollution was not easy to remove.
At present, there are two main categories of waterproof materials on the market:
One is a polyurethane waterproof coating.
This kind of material is generally made of polyurethane and coal tar as raw materials. The volatilized tar gas is toxic and it is not easily removed. Therefore, it was banned from use in China in 2000.
Polyurethane waterproof coatings are still being marketed, using asphalt as a raw material instead of coal tar. However, when such a coating is used, it is generally diluted with an organic solvent such as toluene or xylene, and thus contains toxicity.
The other type is a polymer cement-based waterproof coating.
It is composed of a variety of water-based polymer emulsions and high-quality cements mixed with various additives. The flexibility of the polymer (resin) is integrated with the rigidity of the cement, making it excellent in impermeability and stability.
Its advantages are convenient construction, low overall cost, short construction period, and non-toxic environmental protection.
Therefore, polymer cement base has become the protagonist of the waterproof coating market.
Experts advise:
Some decoration companies and consumers mistakenly believe that the area of ​​water repellent for interior decoration is not very large. After processing, there are still cement and ceramic tiles. It is not easy to cause pollution.
In actual fact, because the indoor waterproof layer generally has to reach a certain thickness to have the corresponding waterproof function, the use of materials is relatively large. Once the waterproof coating containing the pollutants is used in the waterproof construction, the indoor environment will be polluted for a long time.
At present, the control of interior decoration of the waterproof coating pollution, mainly from the use of materials to control, should be the preferred non-toxic environmental protection waterproof coating.
At present, there are acrylic waterproof coatings and tar-free polyurethane waterproof materials on the market, which have been proved to be non-toxic, odorless and environmentally friendly products. The indoor floor treated with such waterproof coatings can meet the requirements of indoor environmental protection.
Consumers should select materials in reputable markets and choose qualified home improvement companies for construction.
During the renovation process, as long as it is a place where water environment is frequently present, such as kitchens, bathrooms, etc., waterproof treatment should be performed.
The use of waterproof coatings is not only related to the overall effect of residential decoration, but also closely related to the physical health of residents. Waterproofing is a “hidden project†in decoration, and its effect will be presented after a long period of use.
If the waterproof coating contains toxicity, it will become an invisible killer in the home.
Therefore, the choice of waterproof material can not be ignored.
