Embodiment approach

[0036] As an embodiment of the present invention, the inorganic filler includes talcum powder and mica powder; mica powder has good elasticity and toughness, and can improve the insulation, high temperature resistance, acid and alkali resistance, corrosion resistance, and adhesion of cement-based waterproof materials. Strong strength and other characteristics; talcum powder can improve the wear resistance and anti-skid performance of waterproof materials.

[0037] A preparation process of a cement-based waterproof material, the preparation process is applicable to any one of the above-mentioned cement-based waterproof materials, the preparation process comprises the following steps:

[0038] S1: first put the plant straw into 5% NaOH solution and soak for 2-3 hours, take out the softened plant straw, wash it repeatedly, then put it into 50% NaCl solution and boil it for 30-45min to further soften it, Take the plant straw out of the water, rinse it with cold water three times, ...

Abstract

The invention belongs to the technical field of cement-based waterproof materials and particularly relates to a cement-based waterproof material and a preparation technology thereof. The cement-basedwaterproof material comprises, by weight, 15-20 parts of plant straw, 45-50 parts of cement, 25-30 parts of quartz sand, 10-15 parts of inorganic filler, 35-40 parts of polyacrylate solution, 16-20 parts of phospholipid molecule solution, 0.5-1 part of tetramethyl thiuram disulfide, and 1-2 parts of polyether modified organosilicone. According to the preparation technology of the cement-based waterproof material, the softened plant straw is twisted into a thick twist shape through a twisting and segmenting device, besides, segmentation treatment is conducted, and then small twist-shaped plantstalk segments are dispersed in cement mortar; and in this way, the tensile strength of the cement base can be improved, and the cement-based waterproof material is prevented from cracking during use.At the same time, the thick plant straw is of a fluffy porous structure, then the thick plant straw can play a role in water retention similar to ceramsite, the water inside the plant straw can be released in the later stage of the cement mortar, so that the cement can be fully hydrated, and then the strength of the cement-based waterproof material is improved.

Description

technical field [0001] The invention belongs to the technical field of cement-based waterproof materials, in particular to a cement-based waterproof material and a preparation process thereof. Background technique [0002] Cement-based waterproof material is a kind of waterproof material formed by mixing cement and polymer emulsion. "Cement-based" waterproof coating means that the main material of this type of waterproof coating is a powdery waterproof coating made of cement as the base material, mixed with various active chemical substances and auxiliary materials or added with polymer emulsion. The waterproof coating made of various modified additives is used with cement according to a certain ratio. It is a waterproof material with high elasticity of synthetic polymer materials and good durability of inorganic materials. [0003] At present, there are many studies on cement-based waterproof materials. For example, Chinese patent application CN201410576814.X discloses a c...
