Description
Technical field
The present invention relates to building material field, particularly, is a kind of polymer cement waterproof paint.
Background technology
Polymer cement waterproof paint claims again the JS composite water-proof paint, be a kind of organic liquid material that forms with the polymer emulsion such as polyacrylate dispersion, ethylene-vinyl acetate copolymer emulsion and various additive, and the inorganic powder that the mineral filler such as cement, quartz sand, weight matter calcium carbonate and various additive form is by rational proportion, compounded a kind of pair of component, aqueous architectural waterproof paint.
This kind polymer waterproof coating material, its salient features shows the aspects such as tensile strength, elongation at break, low temperature flexibility, bonding strength, watertightness, impermeability; Various performance tests need again to process lower just can obtaining through various different conditions and embody, as, heat treated, alkaline purification, UV treatment, immersion processing etc.; In fact, the raising of coating over-all properties, that is the raising of the aspect such as its thermotolerance, alkali resistance, UV resistant.
For the over-all properties of coating, mainly kind and the proportioning between each component by its component determines, by suitably regulating component and component proportion, can effectively improve the over-all properties of coating; Present polymer cement waterproof paint, its over-all properties is usually take BG/T 23445-2009 as standard, in the actual application, its performance can only satisfy common construction environment usually, for the higher operating mode of environmental requirement, then is short of to some extent, especially for high moisture environments, high alkalinity environment, and the UV environment under the high illumination, adopt present polymer cement waterproof paint, show insuperior.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of asphalt modification polymer cement waterproof paint, this kind waterproof paint can keep good physics and chemical over-all properties under high humidity, high alkalinity, high uviolizing environment, thereby satisfies the construction demand under the severe environment.
The technical solution adopted for the present invention to solve the technical problems is: this asphalt modification polymer cement waterproof paint comprises powder and liquid material;

Embodiment
The present invention is further described below in conjunction with drawings and Examples:
This asphalt modification polymer cement waterproof paint comprises powder and liquid material;
According to Fig. 1, ratio illustrated in Figure 2, described powder comprises: ordinary Portland cement 11, calcite in powder 12, talcum powder 13, dispersion agent 14;
Described liquid material comprises: polyacrylic acid fat liquor 21, softening agent 22, defoamer 23, dispersion agent 24, water 25 also comprise emulsified bitumen 26;
The mass ratio of described powder and liquid material is 10:14;
Wherein, but in described powder and the liquid material each component embodiment taken amount as follows:
Powder:
Ordinary Portland cement: 70kg;
