Problems solved by technology

[0005] At present, there are many water-resistant putties for building interior walls on the market, some of which have low bonding strength and poor adhesion, and some have poor water resistance, are prone to hollowing, peeling, and cracking, which eventually lead to cracking and cracking of the wall. Leakage phenomenon, some chemical properties are unstable, easy to be yellowed and black spots, the interior wall putty with excellent comprehensive performance has almost no

Abstract

The invention discloses waterproof putty for a building inner wall. The waterproof putty is prepared from, by weight, 10-16 parts of polyving akohol, 12-20 parts of hydroxypropyl methyl cellulose, 90-103 parts of coarse whiting, 12-18 parts of paraffin, 8-13 parts of superfine silica powder, 10-16 parts of polyvinyl chloride, 18-24 parts of kaolin, 11-15 parts of talcum powder, 1.3-1.6 parts of higher alcohol fatty acid ester complex, 2.5-3.2 parts of kieselguhr, 1.8-2.2 parts of benzoic acid and 1.2-1.6 parts of lignin. The waterproof putty for the building inner wall is white, fine and high in waterproof intensity, has superior bonding strength, has no hollowing, peeling and crazing phenomena after being moistened, and is free of toxin, odorless and suitable for inner wall plaster, cement mortar, masonry, gypsum plates and other base materials.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a water-resistant putty for building interior walls and a preparation method thereof. Background technique [0002] Putty is a supporting product used for base treatment when building fillers are painted. Putty is generally composed of base material, filler, water and additives. The base material, also known as the binder, is the most important component of the putty, and it mainly plays various functions such as bonding. The filler mainly acts as a filling, and the commonly used ones are calcium oxide, talcum powder and quartz sand. Additives include thickeners, water retaining agents, preservatives, etc. Thickeners and water-retaining agents play the role of water retention, improving storage and construction, and cellulose is generally used. Preservatives are mainly used to prevent deterioration due to corruption during storage. In addition, there are antifreez...
