Water-resistant paint

Abstract

The invention discloses a water-resistant paint. Three ingredients, including a flexibilizer, a compatibilizer, and a reinforcing agent, are added into a dispersion phase of the water-resistant paint; the flexibilizer is one or a mixture of a plurality of components selected from polyvinyl chloride, polyethylene, polypropylene, butadiene-styrene rubber, cis-butadiene rubber, butadiene-acrylonitrile rubber, vinylon, dacron, acrylon, polypropylene, ethylene-propylene rubber, polystyrene, polymethyl methacrylate, polyester, chlorinated polyethylene, chlorinated atactic polypropylene, chlorinated polypropylene, atactic polypropylene, 107 adhesive, polyvinyl alcohol, permalon, chloroprene rubber, chlorosulfonated polyethylene, polyethylene glycol, xytene formaldehyde resin, and reclaimed rubber. Using amount of the flexibilizer accounts for 2 to 50% of that of asphalt. The formula above is capable of improving water resistance, cracking resistance, and strength of asphalt emulsion greatly; the obtained asphalt emulsion is an excellent water-resistant paint, and can be taken as a paving material. It is beneficial for construction improvement, cost reducing, energy reducing, and avoiding of environmental pollution.

Description

technical field [0001] The invention relates to a building waterproof coating, which is a composite asphalt emulsion waterproof coating. It belongs to the field of manufacturing building materials. Background technique [0002] Various types of cement prefabricated panels are used to lay roofs, or cemented roofs, etc., and the potential leakage of joints is naturally a concern of the construction industry, resulting in a variety of waterproof membranes, waterproof cement and waterproof coating. [0003] Waterproof coatings are generally asphalt solution and asphalt water emulsion. Waterproof coatings made of asphalt with organic solvents have been eliminated. The waterproof coating of asphalt water emulsion is a common variety at present, and it is divided into many small varieties due to the difference in composition. But generally speaking, due to the unsatisfactory composition and unreasonable production process, the quality of the prepared waterproof coating emulsion...

AI Technical Summary

Problems solved by technology

Asphalt itself is cold, brittle and hot. To make its emulsion coating have better toughness, it is necessary to add more tall objects, but adding tall objects will cause a compatibility problem between the two. If the property is not good enough (such as: giant ethylene), phase separation will occur, which will affect the stability, fineness, penetration and toughness of the emulsion

If the compatibility of the two is too good, the tall objects will dissolve in the asphalt, (such as: natural rubber) cannot produce a proper network structure, and the toughening effect will not be good.
