Abstract

The invention discloses a silicon dioxide suspension and waterproof polymer cement slurry as well as preparation methods thereof and relates to the technical field of waterproof materials. The silicondioxide suspension is prepared with a sol-gel method. The waterproof polymer cement slurry is prepared from a liquid material and a powder material, wherein the liquid material comprises, in parts byweight, 280-350 parts of a styrene-acrylic emulsion, 150-200 parts of the silicon dioxide suspension, 0.5-5 parts of an organosilicon defoamer, 0.1-5 parts of an anionic dispersant, 0.5-4 parts of asterilizer and 450-570 parts of deionized water, and the silicon dioxide suspension is a home-made silicon dioxide suspension; the powder material comprises 400-600 parts of ordinary Portland cement,300-500 parts of quartz sand, 80-120 parts of triple superphosphate, 0.1-5 parts of a methyl hydroxyethylcellulose ether water-retaining agent and 1-10 parts of a polycarboxylic acid water reducer. The suspension has better dispersity, and the waterproof slurry has excellent ultraviolet resistance, can be exposed for use and has a lotus leaf like structure and a self-cleaning effect.

Description

technical field [0001] The invention relates to the field of waterproof materials, in particular to a silica suspension, a polymer cement waterproof slurry and a preparation method thereof. Background technique [0002] Polymer cement waterproof slurry is a two-component rigid waterproof coating with modified polymer emulsion and cement as the main cementitious material. When in use, the liquid material and powder are fully stirred and mixed on site, and then directly brushed on the base surface. Also called polymer cement waterproof mortar. It has excellent waterproof and moisture-proof effect, convenient construction, high coating strength and strong adhesion, and can be constructed on bases such as masonry, concrete and gypsum board; after the construction is completed, mortar plastering and ceramic tiles can be directly placed on the waterproof membrane. General-purpose waterproof mortar is mainly used for waterproofing of buildings in non-long-term water-immersed envir...
