What flexible waterproof materials are there?
Flexible waterproof material is a kind of material mainly composed of organic material and rubber material. This material has excellent ductility and can show great advantages when used for roof waterproofing. Simple operation, practicality and convenience. At present, flexible waterproof materials are mainly used for roof waterproofing. The following small series will introduce you to what is flexible waterproof material, what kind of material is flexible waterproof material, and what are the application advantages of flexible waterproof material. Brief introduction of flexible waterproof materials Flexible waterproof materials are mostly asphalt, and organic materials such as linoleum are also called linoleum coiled material waterproof layer. It is a waterproof layer formed by using linoleum, glass cloth and other fiber fabrics as the tire layer and using various cementing materials such as asphalt to bond the coiled material to the leveling layer on the roof structure board. Flexible waterproof materials have high tensile strength, large elongation, light weight and convenient construction, but the technical requirements for operation are stricter, and the puncture resistance and aging resistance are not as good as those of rigid materials, so they are easy to age and have short service life. What are the flexible waterproof materials? Flexible waterproof materials (such as coiled material waterproof and coated film waterproof) block the passage of water to achieve the purpose of building waterproof or increase the ability to resist leakage. The most widely used flexible waterproofing material is SBC 120 polyethylene polypropylene composite waterproofing membrane. Building waterproof material started from petroleum asphalt felt, and has a history of 130 years. At present, the waterproof coiled materials available in the world can be divided into several categories: tire-based petroleum asphalt linoleum, synthetic polymer modified asphalt coiled materials and synthetic polymer sheets. Synthetic polymer plates are divided into rubber and plastic, and also into uniform cross-section and reinforcement. Usually, the reinforcement is an internal reinforcement structure to make up for the lack of tensile strength of materials. It is difficult to combine the smooth surface of materials with the surface of building structures characterized by cement firmly and stably. When the water content is higher than 9%, the bonding effect will be greatly reduced. It is more difficult to rebuild the concrete structure on the surface of the constructed coiled material. In order to stabilize the waterproof engineering structure, it is necessary to bond the surface of waterproof coiled material with cement material directly to obtain a stable waterproof structure and facilitate construction. Polyethylene polypropylene double-sided composite waterproofing membrane with rough surface. This technology was patented in China on 1992, and has been widely used in construction, water conservancy, chemical industry and environmental protection projects, with an annual application of more than 3 million cubic meters, and achieved good engineering application results. The application advantage of flexible waterproof material 1) solves the problem that most organic waterproof coiled materials can not be directly bonded with cement materials; 2) There is no requirement for the construction of most organic waterproofing membrane products with low moisture content at the building base (
