Problems solved by technology

However, because acrylate polymers are organic substances, they have limited effect on the problems of low durability and mechanical strength that have plagued the development of polymer cement waterproof coatings for a long time.
At present, polymer cement-based waterproof materials still have poor water resistance, poor weather resistance, and short service life, so they cannot be used for second-level and above waterproof roofs and important waterproof projects.

Abstract

The invention provides weather-resistant polymer modified asphalt cement waterproof paint. The paint is composed of a component A and a component B; when the paint is used, a liquid material is mixedwith a powder material according to a ratio of 1 to (0.8-1.2). The component A is prepared from the following raw materials in parts by weight: 30-60 parts of asphalt, 3-15 parts of SBR, 1-6 parts ofSBS, 8-12 parts of sodium silicate, 5-10 parts of modified silicon dioxide ultrafine powder, 1-6 parts of an emulsifier I, 1-6 parts of an emulsifier II, 0.2-2 parts of an ultraviolet stabilizer, 0.5-2 parts of a stabilizer, 1-5 parts of a dispersant, 0.1-1 part of a defoaming agent, 20-60 parts of water and 0.5-2 parts of a corrosion inhibitor. The component B is prepared from the following raw materials in parts by weight: 25-35 parts of cement, 55-65 parts of calcite powder, 95-105 parts of talcum powder and 0.5-1.5 parts of a water reducer. Polymer modified asphalt, sodium silicate and theultraviolet stabilizer are added into the paint; through adjustment and collocation of composition and ratio of the components, the polymer cement waterproof paint with excellent water resistance, flexibility, compactness and weather resistance can be prepared.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a polymer cement waterproof coating. Background technique [0002] Polymer cement waterproof coating is referred to as JS waterproof coating, J refers to polymer, and S refers to cement, so JS is polymer cement waterproof coating. Polymer cement waterproof coating is a liquid material and supporting powder (made of special cement) which are optimized by combining synthetic polymer emulsion (such as polyacrylate, polyvinyl acetate, styrene-butadiene rubber emulsion, etc.) and various additives. , quartz powder and various additives) compounded two-component waterproof coating, is a kind of waterproof material that not only has high elasticity of synthetic polymer materials, but also has good durability of inorganic materials. It has high cost performance, zero VOC emission, good waterproof performance, good wet substrate construction performance and adhesive performance, so it is favored ...
