Inorganic high-strength filler for coating

Abstract

The invention discloses an inorganic high-strength filler for a coating. The inorganic high-strength filler is prepared by fully mixing 220 to 300 weight parts of white portland cement used as a gelled material, 350 to 550 weight parts of white quartz sand and 150 to 250 weight parts of quartz powder which are used as aggregate, 50 to 100 weight parts of wollastonite powder, and 0.3 to 1.5 weightparts of polypropylene fiber anti-cracking material, and a dry powder material which is prepared by mixing 2 to 8 weight parts of cellulose ether and 10 to 30 weight parts of gelatine powder uniformly by a stirring machine, and packaging. The inorganic high-strength filler can be conveniently coated on a dry wall, is easy and convenient to construct, and is easy to level and polish; and when the inorganic high-strength filler is used as a penetration base layer of an inorganic penetration coating, first coat can be saved during coating construction of an inorganic coating, and the coating system can save materials and labor, is economic and reliable and save energy and is environment-friendly.

Description

technical field [0001] The invention relates to an inorganic high-strength filler used in coatings, in particular to a waterproof and crack-resistant mortar special for coating adhesion bottom, which belongs to a building material. Background technique [0002] In the current traditional coating system, the putty or mortar at the bottom of the coating often has disadvantages such as low strength, high brittleness, easy chalking, easy falling off, and poor crack resistance. Once the above-mentioned problems occur in the bottom putty or mortar, the coating system will If the paint layer is seriously damaged, it is useless no matter how good the paint layer is. Therefore, in addition to the performance of the paint itself, the quality of the paint penetrating the base layer is very important. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a flexible anti-crack protective layer that can be u...

[0002] In the current traditional coating system, the putty or mortar at the bottom of the coating often has disadvantages such as low strength, high brittleness, easy chalking, easy falling off, and poor crack resistance. Once the above-mentioned problems occur in the bottom putty or mortar, the coating system will If the paint layer is severely damaged, it is useless no matter how well it is done. Therefore, in addition to the performance of the paint itself, the quality of the paint penetrating the base layer is very important for the inorganic penetrating paint coating system.
