Problems solved by technology

[0003] Traditional jointing agent materials are mainly made of cement, quartz sand and various additives, which generally have the problem of poor water resistance, which affects the use
[0004] The Chinese patent application number 201310395700.0 discloses a caulking agent whose components include silicone emulsion, acrylic emulsion, bactericide, defoamer and thickener. The material has high dirt resistance and water seepage resistance. Good, but the acrylic resin used in the material is in an oily state. Under normal conditions, the oily acrylic resin should not be used in a humid or water environment, otherwise it will cause peeling, peeling, etc.

Abstract

The invention discloses crack filler. The crack filler is prepared from components in parts by weight as follows: 30-40 parts of waterborne polyurethane-acrylic resin, 1-2 parts of a curing agent, 5-10 parts of quartz powder, 2-5 parts of ground calcium carbonate, 0.5-1.5 parts of a dispersing agent, 0.3-1 part of a polyurethane associative thickener, 5-6 parts of a retarder and 0.8-1.2 parts of a water-retaining agent. The crack filler is enabled to have good abrasion resistance, hydrophobicity and weather fastness due to addition of the waterborne polyurethane-acrylic resin; the crack filler has good viscosity, and the bonding degree of the crack filler can be increased; the crack filler is uniformly mixed and avoids caking; aluminum stearate can exist in a film form, and the crack filler is less affected by water; the easy-to-clean performance of the crack filler can be improved by means of organic bentonite.

Description

technical field [0001] The invention relates to the field of building filling materials, in particular to a jointing agent. Background technique [0002] Pointing agent, also known as caulking agent and grouting agent, is mainly used as a material for filling the gaps between tiles or stones. It cooperates with decorative materials such as tiles and stones to provide a beautiful finish and ensure the bonding and safety between facing tiles. anti-seepage. [0003] The traditional jointing agent materials are mainly made of cement, quartz sand and various additives, and generally have the problem of poor waterproofness, which affects the use. [0004] The Chinese patent application number 201310395700.0 discloses a caulking agent whose components include silicone emulsion, acrylic emulsion, bactericide, defoamer and thickener. The material has high dirt resistance and water seepage resistance. Good, but the acrylic resin used in the material is in an oily state. Under normal...
