Problems solved by technology

It is understood that nearly 90% of the tile-laying projects in my country still use on-site mixing of cement and sand (or adding a little construction glue on site) for construction. Not only is the labor intensity high, the construction environment is poor, and the final paste safety hazard is great, especially in recent years. , There are more and more quality problems such as hollowing and shedding of vitrified tiles with large size and low water absorption in the pasting project; moreover, although about 10% of the tiling projects use ceramic tile adhesives, there are still some problems due to materials and tiles. There are a series of problems such as mismatch, low early strength, short airing time, slippage, etc., and it is easy to flow and damage the flatness of the finish during construction, and the construction efficiency and paste safety have not been actually improved.

Abstract

The invention discloses ceramic tile adhesive, comprising the following components according to parts by weight: 300-400 parts of ordinary Portland cement, 50-100 parts of heavy calcium, 200-250 parts of 40-mesh to 70-mesh quartz sand, 350-400 parts of 70-mesh to 100-mesh quartz sand, 10-20 parts of redispersible emulsion powder, 4-8 parts of organosilicon water repellent, 2-3.5 parts of cellulose, 1-1.5 parts of lignocellulose and 1-2 parts of polyvinyl alcohol. The ceramic tile adhesive has high adhesive powder and low plasticity, is good in constructability and is resistant to aging.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an adhesive used for ceramic tiles. Background technique [0002] Ceramic tile facing system is one of the most commonly used decorative facings in my country's construction projects; it has the characteristics of strong impact resistance, good durability, and easy cleaning; but it is often accompanied by several stubborn problems such as water seepage, hollowing, and shedding . At present, the commonly used bonding and caulking materials for ceramic tile finishes in China include: pure cement slurry, cement mortar, tile adhesive and silica gel. Among these materials, pure cement and cement mortar have high rigidity and high water absorption rate, which will generate strong internal stress of thermal expansion in hot summer and strong internal stress of expansion when the system freezes after absorbing water in severe cold winter. Because cement is a hydra...
