Description
Technical field
The present invention relates to a kind of asphaltic base waterproof paint, be mainly used in water-tight corrosion-proof field coating, especially relate to a kind of asphalt polymer cement waterproof paint.
Technical background
Also there is poor water resistance in current polymer cement-based waterproof material, work-ing life is short, can not be used for secondary and above water-proof roofing and important waterproofing work.During the liquid material of acrylate polymer emulsion as polymer cement waterproof paint, there is the shortcomings such as poor water resistance, affect the water-proof function of polymer waterproof coating material.Pitch has the advantages such as material source is extensive, cheap, the mineral acid of ability lower concentration, alkali and salt corrosion, and himself waterproof, there is certain self-healing.
Summary of the invention
This product is a kind of antiseep and etch-proof asphalt polymer cement water-proof film, has excellent binding property, self-healing, protected object is sealed completely, seamless; Acid-alkali-corrosive-resisting; Uvioresistant and biological degradation; Outstanding antistripping ability; The excellent specific property such as nontoxic, tasteless, pollution-free becomes the outstanding person in international waterproof, aseptic production.
Emulsified bitumen in this system is the development of this system specially, and compared with common emulsified bitumen, this emulsified bitumen has and modified latex, the better consistency of sand-cement slurry, ensures the waterproof quality of product, improves the application property of product.
This product has been widely used in waterproof and the protection against corrosion fields such as building construction, municipal traffic, petrochemical industry electric power, environment protection, oceanographic engineering, hydro project.This product and technology embody the development of international waterproof and corrosion-resistant field initiative.
Technical scheme involved in the present invention:
Asphalt polymer cement waterproof paint, is made up of component A and B component, and component A comprises emulsified bitumen, modified latex, and B component comprises cement, filler, auxiliary agent, wherein the content of various raw material in A, B component, and (as follows) meter is as follows by weight percentage:
Component A: emulsified bitumen: 20%-50%
Modified latex: 30%-50%
Water: 10-30%
B component:
Cement: 40%-60%
Filler: 20%-40%
Auxiliary agent: 1%-5%.
Emulsified bitumen composition of the present invention: pitch 50%-65%; Preferred 58%-63%,
