Abstract

The invention discloses a waterproof paint which comprises thermoplastic styrene-butadiene rubber, asphalt and solvent oil. The waterproof paint also comprises drier and filler, wherein the drier is composed of one or more oxides of cobalt, manganese, zinc and calcium; and the filler is talcum powder, fly ash, pulverized asbestos, vermiculite powder, mica powder, heavy calcium carbonate or light calcium carbonate. Due to the adoption of styrene-ethylene-butylene-styrene block copolymer (SEBS), the waterproof paint of the invention has the advantages of excellent elasticity, low-temperature flexibility, low temperature resistance and aging resistance, and does not flow at high temperature, thereby improving the quality of products and widening the use temperature range of the products.

Description

technical field [0001] The invention relates to a coating, in particular to a waterproof coating. Background technique [0002] Waterproof coatings are solvent-based, water-based coatings made of synthetic polymers, polymers and asphalt, polymers and cement as the main film-forming substances; adding various additives, modified materials, filling materials, etc. Cream or powder coatings. At present, the waterproof coating is modified asphalt with waste rubber and polystyrene foam. The specific process is to regenerate and desulfurize the waste rubber powder under the action of a compound regenerant, and then heat and mix with asphalt, and then add waste polystyrene foam after mixing. It is blended with the anti-aging agent, and then an appropriate amount of solvent and chlorinated paraffin are added to the rubber compound, and the surface-modified fly ash is added to mix and stir to obtain the finished product. Though this waterproof paint used raw material is cheap, makes...
