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 CN 02115787 .1 publicly reported a polymer water-soluble rubber powder adhesive, which is mainly composed of guar gum, hydroxypropyl squash gum powder, etc. Because the agent is modified by hydroxypropylation, its water solubility, adhesiveness and environmental protection have been greatly improved, but a multifunctional wall scraping putty powder has been reported, which is mainly composed of guar gum , plant dragon rubber powder, etc., although its environmental protection and comprehensive performance have been improved, but its 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

Abstract

The invention provides a tile adhesive. The tile adhesive is prepared from components of raw materials in parts by weight as follows: 20-40 parts of heavy metal sludge, 5-10 parts of methylethylcellulose ether, 5-10 parts of methyl hydroxypropyl cellulose ether, 8-28 parts of starch ether, 30-50 parts of an acrylic pressure-sensitive adhesive solution and 3-10 parts of triterpenoid saponins. The tile adhesive has the advantages of rapid hardness, early strength, high strength and small shrinkage deformation; by means of the adhesive, the mechanical performance and the durability of a slurry-aggregate interface can be improved.

Description

technical field [0001] The technical field of building materials of the present invention particularly relates to a ceramic tile adhesive and a preparation method thereof. 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. It is generally made of cement, quartz sand, polymer cement and various additives through mechanical mixing. Tile adhesive is mainly used to bond tiles and tiles, also known as polymer tile bonding mortar. The tile adhesive reduces the dependence of the traditional construction process on the process of watering the base and soaking the bricks, and better avoids insufficient watering due to soaking the bricks. Mix a pack of materials according to the specified water ratio,...
