Introduction of building waterproof materials
1, building waterproof material
Building waterproof material is the foundation of waterproof engineering, and it is an obstacle to ensure that buildings and structures are not invaded by rain and groundwater. The quality of waterproof materials has a great influence on waterproof engineering. Therefore, it is necessary to study the waterproofness of waterproof materials.
2, the composition of building waterproof materials
Grace asphalt-free building waterproofing membrane is a kind of multi-layer composite waterproof material with excellent performance, including high-performance PE film, pressure-sensitive adhesive layer and unique granular layer.
3. AA-JA building waterproof coating is a polymer synthetic material.
It will appear as a viscous liquid at room temperature. After being coated on the surface of the base, the solvent will evaporate or the water will evaporate or the chemical reaction between the components will form a tough waterproof film, which is waterproof and moisture-proof. The coating waterproof film is complete, seamless, light in weight, simple in construction, easy to maintain and long in service life. If waterproof coating is used in combination with sealing and potting materials, it can improve waterproof performance, effectively prevent leakage and prolong the durability of waterproof layer.
4. Polyether is the main raw material of waterproof coating, and various additives are added. It is a one-component flexible coating without volatilization of organic solvent. Low solid content, high strength, elongation greater than 90%, tensile strength greater than 65438 0.9%.
Second, what is building waterproof material?
1, what are the functional characteristics of building waterproof materials?
There are several types of waterproofing membrane: PVC waterproofing membrane; Chlorinated polyethylene waterproofing membrane; Polymer waterproof material; Elastomer modified asphalt waterproofing membrane, called "SBS membrane"; Plastic modified asphalt waterproofing membrane, collectively referred to as "APP membrane"; Modified asphalt polyethylene tire waterproofing membrane; Linoleum; Aluminum foil linoleum; Ternary butadiene rubber waterproofing membrane; Chlorinated polyethylene-rubber mixture waterproofing membrane; Self-adhesive rubber asphalt waterproofing membrane; Polymer waterproofing membrane adhesive; Self-adhesive polymer modified asphalt ester peptide waterproofing membrane.
Three, the classification of building waterproof materials
1, roofing waterproof material
The roof has been exposed to the sun for a long time, and the temperature difference between day and night is still very large. Therefore, it is very necessary to waterproof the roof. When used, waterproof materials with good aging resistance can be selected, such as polyester tire modified asphalt. Coil, EPDM rubber sheet or asphalt felt.
2. Waterproof materials for ground buildings
The ground is wet for a long time, with small temperature difference, which is easy to be moldy and corroded. Therefore, ground waterproofing is very important. Choose flexible materials with good corrosion resistance and long service life, such as glass fiber tires and polyester tires. Asphalt roll, glass cloth linoleum, etc.
3, kitchen and bathroom waterproof materials
The rooms in the kitchen and bathroom are not very big, and there are many yin and yang angles. Kitchen and bathroom use a lot of water and are prone to water leakage. Therefore, waterproofing is necessary, and JS composite waterproof coating can be used to choose seamless coating method. Butyl latex asphalt coating, polyurethane waterproof coating, etc.
