Problems solved by technology

Therefore, its construction quality is difficult to guarantee
When pasting large tiles with low water absorption, the back of the tiles is dense and smooth, and the grout cannot penetrate into the back of the tiles, which is prone to falling off

Abstract

A saltpetering-free high-strength tile adhesive is composed of the following raw materials in percentage by weight: 23 to 30% of high aluminium cement, 42 to 50% of fly ash, 12 to 16% of blast furnace slag, 6 to 10% of heavy calcium carbonate powder, 3 to 6% of redispersable emulsion powder, 0.5 to 1% of antifoaming agent, 0.1 to 0.5% of cellulose ether, and 0.2 to 0.5% of saltpetering inhibitor. By using the provided adhesive, saltpetering will not appear on the tile surfaces or the gaps between the tiles. The provided adhesive also has the advantages of strong adhesive force, draping resistance, slippage resistance, good waterproof performance, and excellent thermal aging (70 DEG C) resistant property, and can tolerate the changes of dryness and dampness or freezing and thawing. The problems of saltpetering, hollowing, and peeling off of tiles are solved.

Description

technical field [0001] The invention belongs to the field of building tile adhesives, and in particular relates to a high-strength tile adhesive without efflorescence phenomenon during use. Background technique [0002] The rapid development of tiles has made a significant contribution to beautifying the city and home environment. The traditional tile paste method mostly uses cement mortar, which is to mix sand and cement on site to make simple cement mortar. Apply this mortar to the back of pre-soaked or pre-wet tile, press the mortar-coated tile onto the pre-wet surface, and tap the tile to ensure a consistent level of tile. The main purpose of this process is to compact the mortar so that the cement particles get inside the porous backing of the tile and into the porous substrate. The disadvantages of this kind of mortar are easy to efflorescence, thick coating, weak adhesion, poor durability, easy to peel off, and large amount of construction materials. At the same ti...
