Polymer modified bitumen waterproof coating
Polymer modified bitumen waterproof coating is a water-emulsion or solvent-based waterproof coating prepared by using bitumen as the base material and modified with synthetic high molecular polymers.
Refers to a water-emulsion or solvent-based waterproof coating made of asphalt as the base material and modified with synthetic high molecular polymers, mainly various rubbers. This type of coating can also be called rubber-modified asphalt waterproof coating, which has greatly improved flexibility, crack resistance, tensile strength, high and low temperature resistance, and service life compared with asphalt-based coatings.
The main varieties are
Recycled rubber modified asphalt waterproof coating,
Water emulsion type neoprene rubber asphalt waterproof coating,
SBS rubber modified asphalt waterproof coating, etc.
It is suitable for waterproofing projects such as roofs, grounds, concrete basements and toilets with waterproof grades of II, III and IV.
Recycled rubber modified asphalt waterproof coating
Recycled rubber modified bitumen waterproof coating can be divided into solvent type and water emulsion type according to the different dispersion medium.
Solvent-based reclaimed rubber modified asphalt waterproof coating is made of reclaimed asphalt as modifier, gasoline as solvent, adding other fillers such as talc, calcium carbonate, etc., after heating and stirring. The advantage is that it improves the flexibility and durability of the asphalt waterproof coating, and has a wide range of raw materials, low cost, and simple production. However, due to the use of gasoline as the solvent, attention must be paid to fire prevention and ventilation during construction, and multiple paintings are required to form a better Thick film. It is suitable for the anti-seepage, moisture-proof, waterproof of industrial and civil building roofs, basement pools, bridges, culverts and other projects, as well as the maintenance of old roofs.
Water emulsion type reclaimed rubber modified bitumen waterproof coating is composed of anionic regenerated latex and anionic bitumen latex. The particles of regenerated rubber and petroleum bitumen are stably dispersed in water and formed by the action of anionic surfactants. . The coating uses water as a dispersant, and has the advantages of non-toxic, odorless, and non-flammable. It can be cold-applied at room temperature and can be applied on a slightly damp surface without stagnant water. The coating is generally lined with glass fiber cloth or synthetic fiber reinforced felt to form a waterproof layer, and caulking paste is added during construction to achieve a better waterproof effect. The coating is suitable for waterproofing of concrete base roofs of industrial and civil buildings; waterproofing of thermal insulation roofs with asphalt perlite as thermal insulation; moisture-proofing of underground concrete buildings, renovation of old linoleum roofs, and maintenance of rigid self-waterproof roofs.
Water emulsion type neoprene rubber asphalt waterproof coating
Water-emulsion chloroprene rubber asphalt waterproof coating is composed of cationic chloroprene latex and cationic asphalt emulsion. It is made of chloroprene rubber and petroleum asphalt particles. It is formed by stably dispersing in water with the help of cationic surfactants. A kind of water emulsion type waterproof coating.
Due to the modification with neoprene, the coating has the dual advantages of neoprene and asphalt. It has good weather resistance and corrosion resistance, high elasticity, extensibility and adhesion, and strong adaptability to deformation of the base layer. , The low temperature coating film is not brittle, high temperature does not flow, the coating film is dense and complete, and the water resistance is good. Moreover, the water-emulsion neoprene rubber asphalt paint uses water as the solvent, which not only has low cost, but also has the advantages of non-toxic, non-flammable, and non-environmental pollution during construction.
It is suitable for roof waterproofing, wall waterproofing and floor waterproofing of industrial and civil buildings, basement and equipment pipeline waterproofing, and also suitable for repairing and repairing leaks of old houses.
SBS rubber modified asphalt waterproof coating
SBS modified asphalt waterproof coating is a kind of water-emulsion elastic asphalt waterproof coating composed of asphalt, rubber SBS resin (styrene-butadiene-styrene block copolymer) and surfactants and other polymer materials. The advantages of this coating are good low-temperature flexibility, strong crack resistance, excellent bonding performance, and good aging resistance. It is compounded with glass fiber cloth and other reinforced carcasses. It has good waterproof performance and can be used for cold construction operations. It is an ideal mid-range waterproof coating.
Suitable for waterproof and moisture-proof construction of complex bases, such as toilets, basements, kitchens, pools, etc., especially suitable for waterproofing projects in cold areas
