Vitreous tile adhesive

Abstract

The invention discloses a vitreous tile adhesive which comprises a liquid material component A and a powder material component B. The liquid material component A and the powder material component B are weighed and placed according to the weight proportion of 1:(3-4) and the liquid material component A is poured into the powder material component B to be uniformly stirred without agglomeration. Slurry prepared is placed for 5-10 minutes, and then is uniformly stirred by a stirrer for construction. The liquid material component A comprises the following components in percentage by weight: 70-80 parts of styrene-acrylate emulsion with 40-60% of solid content, 3-5 parts of water-retaining agent, 0-1 parts of mould proof and algae proof agent, 1-2 parts of corrosion remover, 0-2 parts of defoamer and 10-20 parts of purified water. The power material component B comprises the following components in parts by weight: 47-59 parts of cement and 41-53 parts of mineral filler. The vitreous tile adhesive provides a novel product for binding vitreous tiles for construction market and personnel safety and a safe and environmental-friendly material withstanding external environment and weather effect.

Description

technical field [0001] The invention relates to a vitrified tile adhesive, in particular to a vitrified tile adhesive used in the construction industry. Background technique [0002] At present, the interior and exterior decoration markets of home decoration and large clubs, supermarkets and buildings were originally decorated with ceramic bricks with high water absorption (5% to 10%), but because of their low strength, single style and small size, they have been used for decoration. It is not suitable for the needs of the rapidly developing market. Vitrified porcelain tiles have the advantages of low water absorption (the water absorption rate is less than 5 / 1000), high strength, and many specifications and varieties, and have been widely used in the architectural decoration market. Because of its high density and low water absorption, vitrified porcelain tiles use ordinary rigid tile adhesive bonding materials and on-site cement mortar materials to paste this type of porc...

AI Technical Summary

Problems solved by technology

[0004] ①, low bond strength

[0005] ② After the bonded tiles are corroded by rainwater, the bonding strength of the rigid tile adhesive bonding material decreases, and the tiles are easy to fall off

[0006] ③Climate changes in temperature and temperature will cause the cementitious material to be affected by deformation, resulting in cracks at the interface between the cementitious material and the ceramic tile, which will cause the tile to fall off

[0007] ④ Paste polished tiles with high density, imitation stone, many specifications and varieties, low water absorption rate and vitrified porcelain tiles with low adhesion, and cracks usually appear at the interface with the tiles, causing the tiles to fall off

Ordinary rigid tile adhesive adhesive material pastes this type of porcelain tile, often there will be cracks between the adhesive material and the brick surface, which cannot withstand the erosion of rainwater and the influence of cold and hot weather, which will cause the tiles to fall off, seriously It affects the safety of buildings and people, and brings serious safety hazards to the construction market.
