Problems solved by technology

[0005] For example, 02155275.4 "A Preparation Method of Stone Surface Protective Agent" discloses a preparation method of a stone surface protective agent with long-chain alkyl trimethoxysilane, methyl hydrogen-containing silicone oil, etc. as active ingredients. The effect of stone protective agent is good, but the cost is too high to be in line with the cost market in the existing market, and it is not suitable for industrial production and popularization

Embodiment 1

[0038] While stirring, first dissolve 50ml of methyltrimethoxysilane and 10ml of polymethylhydrogensiloxane in 200ml of D40 environment-friendly solvent oil. After 5 minutes, add 1m1 of tetra-n-butyl titanate, continue stirring for 15 minutes, and finally Add D40 environmentally friendly solvent oil to make up to 1000ml, and stir for 10 minutes. Paint on marble, granite, sandstone and travertine respectively, measure the contact angle, record as example 1.

Embodiment 2

[0040] While stirring, first dissolve 50ml of isobutyltriethoxysilane and 10ml of polymethylhydrogensiloxane in 200ml of D40 environment-friendly solvent oil. After 5 minutes, add 1ml of tetra-n-butyl titanate and continue stirring for 15 minutes. , and finally add D40 environmentally friendly solvent oil to make up to 1000ml, and stir for 10 minutes. Paint on marble, granite, sandstone and travertine respectively, measure the contact angle, record as example 2.

Embodiment 3

[0042] While stirring, first dissolve 50ml of dodecyltrimethoxysilane and 10ml of polymethylhydrogensiloxane in 200ml of D40 environment-friendly solvent oil. After 5min, add 1ml of tetra-n-butyl titanate and continue stirring for 15min. , and finally add D40 environmentally friendly solvent oil to make up to 1000ml, and stir for 10 minutes. Paint on marble, granite, sandstone and travertine respectively, measure the contact angle, record as example 3.

Abstract

The invention discloses a solvent-type organic silicon stone protectant and a preparation method thereof. The protectant is characterized by comprising the following polymer monomers by volume percent: at least one alkyl alkoxy silane of which the adding volume accounts for 1% to 10% of the total volume of the polymers, at least one polymethylhydrosiloxane of which the adding volume accounts for 1% to 10% of the total volume of the polymers, at least one titanate catalyst of which the adding volume accounts for 0.05% to 1% of the total volume of the polymers, and at least one solvent oil-type organic solvent of which the adding volume accounts for 79% to 97.95% of the total volume of the polymers. The preparation method comprises the following steps: evenly mixing the alkyl alkoxy silane and the polymethylhydrosiloxane in proportion in partial organic solvents at a room temperature; then carrying out a catalytic reaction by adding the catalyst; and finally, adding the organic solvent and diluting to reach a certain concentration. The protectant which has good permeability can be used for deeply protecting stone and is good in air permeability and recoatability. The protectant is simple in preparation method, simple and convenient to coat as well as relatively low in cost, thereby being suitable for industrial mass production.

Description

technical field [0001] The invention relates to a solvent-type organosilicon stone protective agent and a preparation method. Background technique [0002] Stone is an ancient building material and one of the main decorative materials of modern buildings. The magnificent landscape created by stone decoration can be seen in various places in the city, such as on walls, floors, cylinders, steps, stair handrails and craft decorations, the natural beauty of stone is vividly and beautifully displayed. Huan is widely welcomed by people. [0003] However, we also see that some stone decoration effects are regrettable. Because the user does not know enough about the physical and chemical properties of the stone itself, and has not taken corresponding protection and maintenance measures before the stone is installed or in use, so in the future use, the surface of the stone will appear rust spots, yellowing, water spots, Various lesions such as white blooms, stains, oil spots, moss...
