a tile adhesive

Abstract

The invention relates to the field of adhesives, and provides an environment-friendly and non-toxic ceramic tile adhesive with high adhesiveness and good water resistance. The adhesive comprises the raw materials of, by weight, 20-26 parts parts of linseed gum, 15-22 parts of guar gum, 5-10 parts of urea-formaldehyde resin adhesive, 0.5-1.3 parts of modified starch, 3-4 parts of a de-foaming agent, 1-2 parts of mineral oil, 10-20 parts of a filling material, 30-42 parts of Portland cement, 58-64 parts of quartz sand, 12-17 parts of a polycarboxylate water-reducing agent, and 80-94 parts of water.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a ceramic tile adhesive. Background technique [0002] Environmental protection has become an inevitable trend in the development of building materials, and construction adhesives, which are widely used in the construction industry, are bound to face higher environmental protection requirements. Tile adhesive is one of the commonly used construction adhesives. At present, tile adhesives are mainly prepared from organic materials such as petroleum raw materials, such as vinyl acetate-vinyl polymers, acrylate polymers, polyvinyl alcohol, etc. With the strengthening of the market demand for environmentally friendly tile adhesives, natural vegetable gums have gradually replaced adhesives prepared from petroleum and other organic substances, such as guar gum and kale gum, which have begun to be used in construction rubber powder. Since the natural vegetable gum is modified by catio...

AI Technical Summary

Problems solved by technology

Since the natural vegetable gum is modified by cationic etherification or non-ionic hydroxypropylation, its cohesiveness and water solubility are greatly improved, but its water resistance is poor.

This defect makes it easy to be affected by moisture, easy to corrode, easy to fall off and easy to crack when exposed to the air during application, which will have a certain impact on the quality of the building

Chinese patent CN02115787.1 discloses a polymer water-soluble rubber powder adhesive, which is mainly composed of guar gum, hydroxypropyl squash gum powder, etc., and the adhesive of the invention patent Because it is modified by hydroxypropylation, its water solubility, adhesiveness and environmental protection have been greatly improved, but its water resistance is still very poor, and this technical problem has not been fundamentally solved.

Chinese patent CN99116688.4 discloses a kind of multifunctional wall-scraping putty powder, which is mainly made of guar gum, plant dragon gum powder, etc., although its environmental protection and comprehensive performance have been improved, but its The defect of poor water resistance still exists

Although the above-mentioned invention patent uses natural vegetable glue with better water solubility, which greatly improves its comprehensive performance such as environmental protection, its water resistance is poor, making it easy to fall off, easy to corrode, and easy to turtle in application. Defects such as cracks
