Example Embodiment

[0038] Example 1

[0039] A preparation method of three-in-one mortar for waterproofing, bonding and caulking, including the following steps:

[0040] (1) Weigh cement, quartz sand, acrylic redispersible rubber powder, acrylic redispersible rubber powder, methyl cellulose, alunite expansion agent, fly ash, slag powder, and slag powder according to the content of raw materials in Table 1. , Sand with a particle size of 1~2mm;

[0041] (2) Pour the weighed raw materials into the mixer, stir and mix for 40 minutes to obtain a uniform three-in-one mortar for waterproofing, bonding and caulking.

Example

[0042] Examples 2~5

[0043] The preparation method of a three-in-one mortar for waterproofing, bonding and caulking is the same as that of Example 1, and the addition amount of each raw material is shown in Table 1.

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...
