Embodiment 1

[0015] Weigh 50g of sodium silicate, 50g of methyltrimethoxysilane, and 900g of water into a reaction flask, and stir and react for 8 hours at 70°C. After cooling, an organic-inorganic hybrid solution-type waterproofing agent for the surface of building materials is obtained ( colorless and transparent).

Embodiment 2

[0017] Weigh 200g of potassium silicate, 100g of propyltrimethoxysilane, and 700g of water into a reaction flask, and stir and react for 1 hour at 100°C. After cooling, an organic-inorganic hybrid solution-type waterproofing agent for the surface of building materials is obtained ( colorless and transparent).

Embodiment 3

[0019] Weigh 180g of sodium silicate, 80g of phenyltrimethoxysilane, and 740g of water into a reaction flask, and stir and react for 2 hours at 80°C. After cooling, an organic-inorganic hybrid solution type waterproofing agent for the surface of building materials is obtained ( colorless and transparent).

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 ...
