Preparation method of crack-resistant waterproof glazed putty and products thereof

Abstract

The invention discloses a preparation method of anti-cracking waterproof glaze-surface putty and further discloses a product prepared by implementing the method. Rohm and Haas TM2000 or BATF 300S waterproof emulsion is adopted, and the emulsion has excellent water resistance, flexibility and alkali-resistant elongation. Used auxiliaries are common auxiliaries for building coating, used filling materials are of barium sulfate, talcum powder and calcium carbonate powder preferably, the physical and chemical properties of a coated film can be enhanced by using the filling materials, and the cost can be simultaneously reduced. The preparation process of the method provided by the invention is simple and easy to implement, and the production efficiency is high; and the anti-cracking waterproof glaze-surface putty product provided by the invention has the advantages of good tensile strength, anti-cracking property, water resistance, strong adhesion, smooth and fine surface impression, excellent weather-resistant decoration effect, capability of ensuring the tidy, aesthetic and elegant appearance of a wall body, firmness in binding, good comprehensive performance, better temperature tolerance and weather resistance and simple construction process steps, can greatly shorten the construction period, improve the construction efficiency and realize low cost, and is conductive to extensive popularization and application.

Description

technical field

[0001] The invention belongs to the technical field of putty, and in particular relates to a preparation method of crack-resistant and waterproof glazed putty and products obtained by implementing the method. Background technique

[0002] Putty is a kind of decorative coagulation material for leveling the surface of the wall. It is a thick paste paint and an indispensable product before the paint is painted. Applied on the primer or directly on the object to remove uneven defects on the surface of the object to be coated. It is formulated with a small amount of paint base, a large amount of filler and an appropriate amount of coloring pigments. The pigments used are mainly iron red, carbon black, chrome yellow, etc. Fillers are mainly heavy calcium carbonate, talcum powder and so on. It can fill the partially sunken working surface, or scrape off the entire surface. It is usually applied to the surface of the primer layer after the primer layer is completel...
