At present, the waterproof decorative materials sold on the market can be roughly divided into three types: modified asphalt waterproof decorative materials, which are often used in combination with glass cloth, and the engineering is relatively complicated; polyurethane waterproof decorative materials, such decorative materials generally use toluene The organic solvent of xylene and other components is diluted to contain toxicity; the recently-applied silicone rubber waterproof decorative material is mainly made of polymer synthesis technology, has good waterproof and moisture-proof functions, and is relatively simple to construct.
The importance of waterproof decorative materials in home decoration is unquestionable, but how to choose it? Waterproof application experts remind that when purchasing waterproof decorative materials, in addition to choosing relatively well-known brands, we must also pay attention to raw materials, such as the current waterproofing decoration. Materials should generally contain "silicone-modified acrylic", and Others use "core-shell" technology, and more advanced is the "organic fluorine", these products should be excellent.
Polyurethane waterproof decorative materials: These materials are generally made of polyurethane and coal tar as raw materials. The volatilized oil and gas are highly toxic and difficult to remove, so they were banned in China in 2000. The polyurethane waterproof decorative material that is still being sold is made of asphalt instead of coal tar as a raw material. However, when such a decorative material is used, it is generally diluted with an organic solvent such as toluene or xylene, and thus contains toxicity.
Polymer cement-based waterproof decorative material: it is composed of a variety of water-based polymer emulsions and high-quality cement with various additives. The flexibility of the polymer (resin) is integrated with the rigidity of the cement, making it impervious. Excellent performance in terms of stability. The advantages are convenient construction, low comprehensive cost, short construction period, and non-toxic and environmental protection. Therefore, polymer cement base has become the protagonist of the waterproof decorative materials market.
The wall surface is an important part of the indoor building space, and it is the most sensitive part of the home space. The quality of the wall decoration directly affects the overall effect of the home decoration, but has a good decoration effect.
Waterproof materials should be environmentally friendly and waterproof. It is a concealed project in the decoration. During the decoration process, the quality of the waterproof decorative materials may not be noticed. However, when it is put into use, whether the waterproof material is qualified or not will appear immediately. If there is a problem with the waterproof material, and it is not said that his home is "water flooded", it will also affect the neighbours next door and downstairs, causing serious economic losses. When decorating, be sure to carefully ask about the quality of the waterproof material decoration materials, and also understand its environmental protection. When purchasing waterproof materials, be sure to understand the manufacturer of the product.
There is no worries about the construction of the house to prevent dampness: in addition to the selection of waterproof materials, special measures must be taken during the construction process. When transporting materials, try to choose when the weather is fine. If it is rainy, the material should be protected with a plastic film. If the material is already on the tide, it should not be used again. It should not be used after drying. When using the board at the construction site, it should be padded with wooden squares. It should not be placed directly on the ground, and it should not be placed in a place where the kitchen, the bathroom, the balcony and other places are prone. When carrying out the construction of decorative materials, the base layer moisture-proof primer can not be saved. After the painting is finished, pay attention to ventilation and ventilation, and strive for maximum drying. In addition, the seam king can be selected during the treatment of the wall base layer to ensure that the wall surface will not crack.
