Problems solved by technology

Careful analysis of the above three functions reveals that there are potential performance conflicts among them. For example, sound insulation materials are generally porous and lightweight, with high water absorption, but such materials are not suitable for waterproofing. Therefore, the above Combining the three functional features together to realize the three-in-one performance, solve the problem of repeated construction in practical applications, and save construction costs are the key technical difficulties and innovations of the present invention

preparation example Construction

[0055] Further, for the preparation method of the above-mentioned waterproof material, refer to the attached figure 2 , including the following steps:

[0056] (a) Mix the adsorbent material evenly

[0057] In this step, if the adsorptive material contains one material, it is not necessary to mix, and if it contains two or more materials, it needs to be mixed uniformly.

[0058] (b) mixing the liquid waterproof material with the material obtained in step (a)

[0059] In this step, the specific way of mixing the liquid waterproof material with the material obtained in step (a) is not particularly limited, and those skilled in the art can choose according to actual needs, and the liquid waterproof material can be added to the material obtained in step (a) The material obtained in step (a) can also be added to the liquid waterproof material. As a preferred solution, the liquid waterproof material is added to the material obtained in step (a) in batches for several times, and m...

Abstract

The invention discloses cement-based self-leveling mortar and a preparation method thereof. The cement-based self-leveling mortar is prepared from a cement-based self-leveling mortar matrix and a mixture with sound insulation and waterproof functions, wherein the mixture with the sound insulation and waterproof functions comprises a sound absorption material, a waterproof material and a cementingmaterial. According to the invention, three important characteristics including water resistance, sound insulation performance and self-leveling performance are perfectly fused together, and performance conflicts in respective raw material performances are effectively solved, so the self-leveling mortar with excellent performance and sound insulation and water resistance functions is obtained.

Description

technical field [0001] The invention belongs to the technical field of self-leveling mortar, in particular to a cement-based self-leveling mortar with sound insulation and waterproof functions and a preparation method. Background technique [0002] Cement-based self-leveling mortar with sound insulation and waterproof function is a functional leveling material. Rapid development, loved by the common people. With the rapid development of the construction industry in recent years, and the country's higher and higher requirements for building energy conservation and green building standards, a large number of building materials are required to have more functional features, such as heat preservation, sound insulation, waterproof, etc. Therefore, according to these characteristics, emerging materials such as thermal insulation mortar, sound insulation mortar, and waterproof mortar have emerged, which have brought new choices and solutions to our building construction, but this ...
