Special mortar modifying agent

Abstract

The invention provides a modifying agent capable of improving and enhancing the properties of special mortars such as tile glue, putty and a caulking agent. The modifying agent is prepared from, by weight, 10%-30% of powdery antifoaming agent, 10%-30% of calcium formate and 40-60% of polyvinyl alcohol through mixture, wherein the powdery antifoaming agent is a mineral oil type antifoaming agent produced by Germany MingLing chemical group, the polyvinyl alcohol is cold soluble type polyvinyl alcohol with the polymerization of 1788 or 2488, the special mortar is a ceramic tile adhesive, putty or the caulking agent, and the adding amount of the modifying agent in the special mortar is 0.1-0.2% of the total weight of the special mortar. The adding amount of the modifying agent is very small. Exiting ceramic tile adhesives, putty, caulking agents and other products can obviously improve the compressive strength, surface strength and surface effect of the mortar without original formula and proportion change of the special mortar under the condition that the application property of the mortar is not affected, and the modifying agent is especially suitable for usage in ceramic tile adhesives, caulking agents and internal and external wall putty.

Description

technical field [0001] The invention relates to an additive for mortar, in particular to a modified admixture for special mortar, and more particularly to a modifier capable of improving and enhancing the properties of mortar such as tile adhesive, putty and caulking agent. Background technique [0002] The so-called special mortar refers to the mortar suitable for special requirements such as thermal insulation, sound absorption, waterproof, corrosion resistance, radiation protection, decoration and bonding. Special mortar has become a An indispensable building material in modern home decoration, such as commonly used tile adhesives, caulking agents, putty, etc. Among the problems, the most common one is that there are many internal and surface bubbles, resulting in low surface strength. The reasons for the generation of air bubbles in mortars such as tile adhesives, caulks, and putty are as follows: 1. The addition of cellulose ether, while providing water retention and t...
