A fast-setting tile adhesive

Abstract

A quickly-solidified tile adhesive comprises the raw materials in parts by weight: 20-40 parts of quick-hardening cement, 40-50 parts of quartz sand, 10-20 parts of fly ash, 10-20 parts of calcium carbonate, 2-4 parts of redispersible latex powder, 0.2-0.5 part of cellulose ether, 0.1-0.3 part of starch ether, 0.2-0.5 part of water repellent, 0.1-0.4 part of retarder and 1-5 parts of early strength agent. The quick-hardening cement, the quartz sand and the fly ash are used as raw materials to prepare the quickly-solidified tile adhesive, the adhesive is short and adjustable in initial setting time, the strength growth is fast, the fixed waste fly ash generated by thermal power plants is effectively utilized, the adhesive also contains organic high-molecular polymer capable of being compounded with the ceramic tile and the indoor environment pollution cannot be caused.

Description

Technical field: [0001] The invention relates to a fast-setting tile adhesive. Background technique: [0002] Tile adhesives are mainly used to paste ceramic tiles, facing tiles, floor tiles and other materials. Because tile adhesives can make up for the defects of cement and ordinary polymer mortar, they are widely used in interior and exterior walls, floors, bathrooms, kitchens and other building decorations. At present, cement and sand mixed on site are often used as tile adhesives, and the traditional thick-layer bonding method is used to bond tiles. The annual consumption of yellow sand and cement is as high as more than 1 trillion tons, and there are still problems such as Inadequate bonding, hollowing, cracking, falling off, water seepage and other disadvantages. The polymer-based tile adhesives that are now popularized and used overcome the shortcomings of ordinary tile adhesives due to their waterproof, cohesive and durable properties. However, the existing polym...

AI Technical Summary

Problems solved by technology

However, the existing polymer-based tile adhesives have a long curing time, which is not conducive to construction by construction personnel and reduces work efficiency.

In addition, the existing tile adhesives are relatively expensive in materials, and mostly use toxic low-molecular organic matter as the main component, which will undoubtedly lead to greater indoor environmental pollution and affect people's health.
