Abstract

The invention provides a polymer cement waterproof paint, comprising a powder material and a liquid material, wherein the mass ratio of the powder material to the liquid material is 10:14; the powder material comprises the following components in percentage by weight: 40-60% of portland cement, 28-35% of calcite powder, 15-20% of talc powder and 0.8-1.2% of a dispersant; and the liquid material comprises the following components in percentage by weight: 50-70% of polyacrylate emulsion, 5-8% of a plasticizer, 0.3-0.8% of a defoaming agent, 0.2-0.5% of a dispersant, 3-5% of water, 10-15% of emulsified asphalt and 10-15% of ethylene-vinyl acetate copolymer emulsion. Compared with the current all-purpose polymer cement waterproof paint, the polymer cement waterproof paint provided by the invention has better comprehensive physical and chemical properties and good stability.

Description

A kind of polymer cement waterproof paint

Technical field

The present invention relates to building material field, particularly relate to a kind of polymer cement waterproof paint.

Background technology

Polymer cement waterproof paint claims the JS composite water-proof paint again, be that the inorganic powder formed of mineral filler such as a kind of organic liquor material of forming with polymer emulsion such as polyacrylate dispersion, ethylene-vinyl acetate copolymer emulsion and various additive and cement, quartz sand, weight matter calcium carbonate and various additive 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 aspects such as tensile strength, elongation at break, low temperature flexibility, bonding strength, watertightness, impermeability; The test of various performances needs again just can obtain embodying under various different conditions are handled, as, heat treated, alkaline purification, UV treatment, immersion are handled etc.; In fact, the raising of coating over-all properties, that is the raising of 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 set of dispense ratio, can effectively improve the over-all properties of coating; Present polymer cement waterproof paint, its over-all properties is standard with BG/T 23445-2009 usually, 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

At the problems referred to above, the object of the present invention is to provide a kind of polymer cement waterproof paint, this coating has more good comprehensive physical and chemical performance, and has satisfactory stability compared to present general polymer cement waterproof paint.

The technical solution adopted for the present invention to solve the technical problems is: this polymer cement waterproof paint comprises powder and liquid material, and the mass ratio of described powder and liquid material is 10:14;

Described powder comprises: silicate cement 40% ~ 60%(accounts for the ratio of powder); Calcite in powder: 28% ~ 35%; Talcum powder: 15% ~ 20%; Dispersion agent: 0.8% ~ 1.2%;

Described liquid material package is drawn together: polyacrylic acid fat liquor 50% ~ 70%(accounts for the ratio of liquid material); Softening agent 5% ~ 8%; Defoamer 0.3% ~ 0.8%; Dispersion agent 0.2% ~ 0.5%; Water 3% ~ 5%; Also comprise emulsified bitumen: 10% ~ 15%, the ethylene-vinyl acetate copolymer emulsion 10% ~ 15%.

As preferably, the silicate cement in the described powder is ordinary Portland cement.

Beneficial effect of the present invention is: compared to the general polymer cement waterproof paint, the present invention mainly carries out component to the liquid material in the coating and improves, by adding an amount of emulsified bitumen, and make the content of ethylene-vinyl acetate copolymer emulsion suitable with emulsified bitumen, thereby make this waterproof paint obtain to add the good physical chemistry over-all properties that embodies behind the emulsified bitumen, after performances such as water-fast, alkaline-resisting, ultraviolet-resistant aging, keep satisfactory stability again, not perishable.

Fig. 2 is the over-all properties basic parameter table of general polymer cement waterproof paint.

Embodiment

The present invention is further described below in conjunction with drawings and Examples:

Embodiment one:

In embodiment one, this polymer cement waterproof paint comprises powder and liquid material, and the mass ratio of described powder and liquid material is 10:14;

Described powder comprises: ordinary Portland cement 50%(accounts for the ratio of powder); Calcite in powder: 30%; Talcum powder: 19%; Dispersion agent: 1%;

Described liquid material package is drawn together: polyacrylic acid fat liquor 56%(accounts for the ratio of liquid material); Softening agent 8%; Defoamer 0.5%; Dispersion agent 0.5%; Water 5%; Also comprise emulsified bitumen: 15%, the ethylene-vinyl acetate copolymer emulsion 15%.

Embodiment two: in embodiment two, the component of powder constitutes identical with embodiment one;

Described liquid material package is drawn together: polyacrylic acid fat liquor 70%(accounts for the ratio of liquid material); Softening agent 5%; Defoamer 0.5%; Dispersion agent 0.5%; Water 4%; Also comprise emulsified bitumen: 10%, the ethylene-vinyl acetate copolymer emulsion 10%.

Compared to the general polymer cement waterproof paint, the present invention mainly carries out component to the liquid material in the coating and improves, by adding an amount of emulsified bitumen, and make the content of ethylene-vinyl acetate copolymer emulsion suitable with emulsified bitumen, requirement according to BG/T 23445-2009 is tested, its over-all properties is shown in form among Fig. 1, by with the contrast of Fig. 2, as seen its performance at aspects such as water-fast, alkaline-resisting, ultraviolet-resistant agings all increases, and place by preserving for a long time, still keep stability preferably, not perishable.

The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
