Embodiment Construction

[0023] The raw material component of stone material surface protective agent of the present invention is prepared by following proportioning (weight %):

[0024] Long-chain alkyltrimethoxysilane 5;

[0025] Methyl hydrogen-containing silicone oil (hydrogen content 0.2-1.6%) 3;

[0026] Dibutyltin dilaurate 0.2;

[0027] Absolute ethanol 91.8.

[0028] Using absolute ethanol as a solvent, first add long-chain alkyl trimethoxysilane and methyl hydrogen-containing silicone oil, mix well at room temperature, then add dibutyltin dilaurate as a catalyst, stir and mix thoroughly to obtain a colorless and odorless The transparent stone material surface protection agent of the present invention.

Abstract

The present invention is the preparation process of stone material surface protecting agent. The preparation process includes adopting absolute ethyl alcohol as solvent, mixing with long chain alkyl alkoxy silane and hydrogenous methyl silicone oil at room temperature, and adding dibutyltin dilaurate as organic catalyst through stirring. When it is used, the stone material surface protecting agent is painted directly before letting stand for 24 hr and further construction without needing heating for crosslinking. It may be used in repairing fine holes and cracks without blocking the capillary tracts, and it can form excellent hydrophobic effect while not blocking inside water vapor to diffuse outwards.

Description

[0001] Field [0002] The invention relates to a preparation method of a stone surface protection agent, in particular to a preparation method of a surface protection agent for granite, sandstone, marble building stone, cultural relic stone carvings and polished tiles. Background technique [0003] As we all know, natural stones such as marble, granite and sandstone are widely used in buildings as wall and floor materials for high-rise buildings, making buildings look luxurious and beautiful. However, such stones are microporous and easily absorb moisture, pollutants and corrosive gases in the atmosphere. Various stone diseases will occur during use, such as water spots, yellowing, mold spots, Bianstone alkali and various immersion pollution, which will cause the original bright stone to lose its decorative effect, and it is very difficult to clean and treat. In order to prevent the pathological changes of stone, stone surface maintenance and treatment technologies have appea...
