Waterproof, bonding and joint filling three-in-one mortar and preparation method thereof

Abstract

The invention discloses waterproof, bonding and joint filling three-in-one mortar and a preparation method thereof, and belongs to the technical field of building materials, wherein the waterproof, bonding and joint filling three-in-one mortar comprises the raw materials: cement, quartz sand, a high-molecular polymer, a construction auxiliary agent, an alunite expanding agent, an admixture and sand. Through the synergistic effect of the high-molecular polymer and the construction auxiliary agent, the mortar is firm in bonding while being waterproof; the alunite expanding agent is added into the mortar, so that the tensile strength of the mortar is improved, and the mortar is prevented from cracking; the admixture is used in the mortar, so that waste utilization is realized.

Description

technical field [0001] The invention relates to the technical field of building materials, more specifically, it relates to a three-in-one mortar with waterproofing, bonding and caulking and a preparation method thereof. Background technique [0002] Ceramic tile facing system is one of the most commonly used decorative facings in construction projects in my country. It has the characteristics of strong impact resistance, good durability, and easy cleaning; but it is often accompanied by problems such as water seepage, hollowing, and falling off. At present, the commonly used adhesive and caulking materials used for tile decoration include: pure cement slurry, cement mortar, flexible tile adhesive, silica gel, etc. Pure water mortar and cement mortar have high rigidity and high water absorption, which will generate internal expansion stress; flexible tile adhesives have great plasticity, and are easy to flow and damage the smoothness of the finish during construction; silica...

AI Technical Summary

Problems solved by technology

Pure water mortar and cement mortar have high rigidity and high water absorption, which will generate internal expansion stress; flexible tile adhesives have great plasticity, and are easy to flow and damage the smoothness of the finish during construction; silica gel is expensive, easy to age, and will Difficult to control flatness

[0003] Due to the large shrinkage value of ordinary mortar, it is easy to crack and fall off after a long time. Therefore, it is necessary to develop mortar with excellent waterproof, bonding and caulking properties.
