A tooth-shaped waterproof material for preventing tile hollowing

Abstract

The invention provides a tooth-shaped waterproof material for preventing ceramic tile hollowing. The tooth-shaped waterproof material is composed of the following components in parts by weight: cement: 500-700 parts; quartz sand: 200-350 parts; metakaolin : 20 to 70 parts; Cellulose: 1 to 5 parts; Calcium formate: 2 to 20 parts; Water reducer: 1 to 8 parts; Thixotropic agent: 8 to 30 parts; VAE emulsion: 300 parts ~500 parts; the tooth-shaped waterproof material, through the combination of the raw materials and the ratio of the raw materials, the flexural strength and compressive strength of the waterproof material are increased; the waterproof performance is good, and the alkali resistance and heat resistance test , no cracking, short solidification time, easy to shape, when the sawtooth-shaped scraper plate is applied on the waterproof material, the tooth marks scraped out are easy to shape, so that the combination with the tile and the adhesive is strong, and the tile and waterproof material The bonding force between them is large, which effectively prevents the phenomenon of hollowing when the tile bonding material shrinks.

Description

technical field [0001] The invention relates to the field of interior decoration, in particular to a tooth-shaped waterproof material for preventing tile hollowing. Background technique [0002] At this stage, the strength of the base layer of the wall is not enough, which will easily lead to the delamination of the tile waterproof layer and the base layer, and the base layer needs to be reinforced; and the bonding material with the tile is not strong enough. Most of the existing wall waterproofing materials are cement-based or acrylic or polyurethane coatings, which easily lead to poor firmness of the wall surface and poor bonding force with ceramic tiles; The unreasonable ratio causes the waterproof material on the wall to flow and the setting performance is poor. [0003] In addition, the scrapers at this stage are all square sawtooth, and the scratches of the square sawtooth scraper, when the ceramic tile and adhesive material are combined with waterproof material, the ...

Problems solved by technology

[0002] At this stage, the strength of the base layer of the wall is not enough, which will easily lead to the delamination of the tile waterproof layer and the base layer, and the base layer needs to be reinforced; and the bonding material with the tile is poor in firmness

Most of the existing wall waterproofing materials are cement-based or acrylic or polyurethane coatings, which easily lead to poor firmness of the wall surface and poor bonding force with ceramic tiles; The unreasonable ratio leads to the flow of waterproof material on the wall and poor shaping performance

[0003] In addition, the scrapers at this stage are all square sawtooth, and the scratches of the square sawtooth scraper, when the ceramic tile and the adhesive material are combined with the waterproof material, the adhesive material shrinks, and the paint layer will appear hollow
