Organic-inorganic hybrid solution type water repellent for surfacers of building materials and preparation process thereof

Abstract

The invention relates to an organic-inorganic hybrid solution type water repellent for surfaces of building materials and a preparation process thereof. The organic-inorganic hybrid solution type water repellent for surfaces of building materials is characterized by being prepared by raw materials including 5-20 parts of silicate, 5-10 parts of alkoxy silane, 70-90 parts of water and the like. The organic-inorganic hybrid solution type water repellent for surfaces of building materials has the advantages of environment-friendly property, simple process and excellent water proofing performance.

Description

technical field

[0001] The invention relates to a waterproofing agent for the surface of building materials and a preparation method thereof, in particular to an organic-inorganic hybrid solution type waterproofing agent and a preparation method thereof. Background technique

[0002] my country's investment in construction projects is increasing year by year. At present, the proportion of waterproof project cost in the total project cost is as high as 15%. Although the investment is so large, the waterproof effect is not ideal, and the leakage rate of new projects is about 10%.

[0003] Existing waterproofing agents mainly include organic silicon and inorganic silicate two kinds of waterproofing agents. Silicone waterproofing agents mainly include methyl silicate aqueous solution, silicone solvent-based waterproofing agent, and active silicone oil emulsion. Their disadvantages are: the emulsion is unstable, contains a large amount of volatile organic compounds, and has poor ...
