The building envelope shall prevent the infiltration of rain, snow, and groundwater; it shall prevent the ingress of moisture, steam, and other harmful gases and liquids in the air; the partition structure shall prevent the infiltration of water and drainage. These anti-permeation, leakage and erosion materials are collectively referred to as waterproof material.
Prevent rainwater, groundwater, industrial and domestic water supply and drainage, corrosive liquids, and moisture, steam, and other materials that intrud into buildings. The areas where buildings need to be treated with water are mainly roofs, walls, floors and basements.
A wide variety of waterproof materials, according to its main raw material is divided into four categories: 1 asphalt waterproof material. The natural asphalt, petroleum asphalt and coal asphalt as the main raw materials, made of asphalt linoleum, asphalt tire felt, solvent-based and water emulsion bitumen or asphalt rubber coatings, ointments, with good adhesion, plasticity, Water resistance, corrosion resistance and durability. 2 rubber plastic waterproof material. With neoprene rubber, butyl rubber, ethylene propylene diene monomer, polyvinyl chloride, polyisobutylene, and polyurethane as raw materials, it can be made into elastic tireless waterproof membrane, waterproof membrane, waterproof coating, coating material and ointment, cement Sealing materials, such as sealing tapes, have high tensile strength, high elasticity and elongation, good adhesion, water resistance, and weather resistance. They can be used coldly and have a long service life. 3 cement waterproof material. Admixtures with a coagulative effect on cement, such as water repellents, air entrainers, and swelling agents, can increase the hydrophobicity and impermeability of cement mortars and concrete; and promote coagulation with cement and sodium silicate as base materials. Mortar, can be used for underground engineering plugging and waterproofing. 4 metal waterproof material. Thin steel plate, galvanized steel plate, profiled steel plate, coated steel plate, etc. can be directly used as roofing panels for waterproofing. Thin steel plates are used for metal waterproofing of basements or underground structures. Thin copper plates, thin aluminum plates, and stainless steel plates can be used as waterproofing strips for building deformation joints. The connection of the metal waterproof layer is to be welded and painted with a rust-proof protective paint.
Waterproof coatings are divided into four major categories: hard plasters, flexible mortars, acrylates, and one-component polyurethanes.
According to the classification of material properties, there are mainly three types of waterproof materials:
1, waterproof membrane, mainly used for engineering construction, such as roof, exterior wall, basement, etc.;
2, 911 polyurethane waterproof material,
Contain volatile gas, strict construction requirements, and costly;
3. New polymer cement-based waterproof material, which is composed of organic polymer liquid material and inorganic powder material. It combines the characteristics of high elasticity of organic materials and durability of inorganic materials. After coating, it forms a strong and tough waterproof coating film. , This new type of material can be perfectly integrated with the cement base surface, and does not delaminate after long time. It is a common choice for household waterproofing.
JS composite waterproof coating is also called cement-based polymer waterproof coating and elastic cement waterproof coating. It is a two-component waterproof coating composed of organic liquid and inorganic powder. With the dual advantages of organic material flexibility and inorganic powder material durability, it is a new green product promoted by the Ministry of Construction.
Water-based paint, non-toxic, harmless, non-polluting, excellent environmental performance.
The coating has high tensile strength, water resistance, low temperature flexibility and crack resistance.
Can be applied on a moist base and bonded firmly.
Easy to use, simple ingredients, easy to operate, quick cold coating, high ergonomics, short construction period, suitable for waterproofing of irregular roofs, and also for immediate construction after raining.
