Preparation method of water-based organosilicone stone protecting agent

Abstract

The invention discloses a preparation method of water-based organosilicone stone protecting agent, wherein the protecting agent is prepared from, by weight, 50-75 parts of long-chain alkylsilane modified methyl silicate solution, 5-10 parts of silica sol, 5-10 parts of polyving akohol, 1-5 parts of water-based adhesive promoter. The stone protecting agent takes water as the dispersing agent, and is low in cost, safe and toxic-free; the processed stone is free from the change of appearance and color, and has good penetration performance, strong adhesive force, fast curing, and high dilution ratio; the protecting agent can form protection at the surface and the inner part of the stone, and comprehensively improve the protection performance.

Description

technical field [0001] The invention relates to the technical field of stone protection, in particular to a water-based organosilicon stone protection agent and a preparation method thereof. Background technique [0002] Due to its advantages in decoration and strength, stone is one of the important building materials, and is highly valued and favored by people. Then the porous nature of the stone itself makes the stone vulnerable to the influence of the external environment. Under the action of natural factors such as sunlight, weathering and acid rain erosion, it is prone to disease, decomposition and fragmentation, which seriously affects the beauty and service life of the stone. Therefore, the protection of stone is necessary. [0003] The purpose of protection is to limit the pollution of stone materials and avoid problems such as water spots, stains, and pulverization of stone materials during use. At present, there are many types of stone protective agents in the ma...

AI Technical Summary

Problems solved by technology

Most of the existing high-end stone protective agents are solvent-based, but there are problems such as high production cost, inconvenient use and toxic side effects, so water-based is the development direction of stone protective agents

[0004] Methyl silicate is a kind of water-based silicone water repellent, which has long curing time and easy whitening, which affects the finishing efficiency and appearance. Organosilicon waterproofing agent for building materials is a waterproofing agent made of sodium methyl siliconate, silane coupling agent, fatty alcohol polyoxyethylene ether succinate half ester sulfonate, alum, phosphoric acid, polyethylene glycol and water; publication number CN103571327 discloses a method for preparing stone waterproofing agent with methyl silicate, silane coupling agent and polyethylene glycol as raw materials; however, the products of existing water-based technology are used for stone protection, and have not yet overcome methyl The disadvantage of sodium silicate is that the curing time is long. Therefore, the advantages of methyl silicate waterproofing agent are still needed in high-end stone protection to overcome its shortcomings.
