Spray quick-setting rubber asphalt waterproofing coating consists of rubber asphalt emulsion A component and emulsion-breaking agent B component. A component consists of high solids emulsified asphalt and polymer. It will be co-blended modified to form a water-soluble mixture of polymer and emulsified asphalt. component A and component B is sprayed from the two nozzles of the special spraying equipment on site, atomized mix quickly after breaking the emulsion dehydration (within 10 s), coagulation into a film. After efforts, a dense, continuous and complete rubber asphalt coating is formed with high elongation, strong elasticity, excellent durability and waterproof, anti-corrosion, impermeability and protection. A spraying can reach more than 2 mm thickness, fast construction speed, environmental protection.
To achieve the excellent product performance of spraying fast-setting rubber asphalt waterproof coating, the first step is to produce emulsified asphalt that meets the requirements of spraying fast-setting rubber asphalt waterproof coating. The main requirements of emulsified asphalt.
1. Solid content should be high, greater than 58%.
2. The particle size should be smaller, less than 5mm, the smaller the particle size, the more delicate and dense coating film.
3. Good compatibility with latex.
4. Fast emulsion breaking speed.
5. Good mechanical stability. Emulsified asphalt is mixed with rubber latex through mechanical mixing. At the same time, the product is sprayed in the construction of high-speed high-pressure shear force.
6. Good storage stability, the product will not stratify and precipitate during storage.

Construction Technology of PVC Waterproof Rolls
1. Firstly, waterproof materials and various construction tools need to be prepared, followed by the specific construction process. Firstly, the treatment of the base layer must be carried out. Before construction, the base layer must be cleaned to ensure that there are no other lumps or debris, and the base layer must be dry, with a moisture content within 9%.
Talking about the scope of application of non-curing waterproof coatings
Application scope of non-curing waterproof coating 1, underground buildings Such as subway tunnel waterproof plugging, pool cistern wall waterproof patching anti-corrosion heat insulation transformation, basement floor water leakage management repair reinforcement, etc.
Waterproof material variety, which are the main raw materials?
Waterproof material is the building envelope to prevent the infiltration of rain, snow and groundwater; to prevent the erosion of moisture, steam and other harmful gases and liquids in the air; to separate the structure to prevent the seepage of water supply and drainage over.
Do you know what are the characteristics of non-curing waterproof coating?
Non-curing waterproofing coating is not need to heat to a certain temperature on the construction of the material. There are many types of such materials, such as: polyurethane waterproofing roll-roofing and non-vulcanized rubber-based polymer emulsions belong to such products; in addition, there are acrylic polymer cement mortar and modified epoxy resin cement also belongs to this category.
Introduction to the construction steps of liquid coil
Liquid membrane is a highly elastic rubber waterproofing material, with water instead of organic solvents, green and environmentally friendly. After painting and coil effect is the same, so compared with ordinary coil construction is very simple. And not subject to any complex grass-roots shape restrictions, can be made into a continuous overall highly elastic seamless waterproof membrane, is an ideal environmentally friendly waterproof coating.
