Embodiment 1

[0037] First, add 120 g of sodium methyl silicate and 14.2 g of silane coupling agent KH-550 to 200 mL of water under stirring. After stirring and reacting for a period of time at room temperature, make up to 1000 mL of water. Paint on marble, granite, sandstone and travertine respectively, measure the contact angle, record as example 1.

Embodiment 2

[0039] First, add 120g of sodium methyl silicate and 21.1g of silane coupling agent KH-550 to 200mL of water under stirring. After stirring and reacting for a period of time at room temperature, make up to 1000mL of water. Paint on marble, granite, sandstone and travertine respectively, measure the contact angle, record as example 2.

Embodiment 3

[0041] First dissolve 10g polyethylene glycol (PEG2000) in 200mL deionized water, add 86g sodium methyl silicate and 28g silane coupling agent KH-550 to it in sequence while stirring, and then add water to 1000mL after uniformity. Paint on marble, granite, sandstone and travertine respectively, measure the contact angle, record as example 3.

Abstract

The invention discloses a methyl silicate stone protecting agent and a manufacturing method thereof. The methyl silicate stone protecting agent comprises a methyl silicate, at least one type of silane coupling agent, at least one type of polyethylene glycol and at least one type of water, wherein the adding amount of the methyl silicate is 8-20% of the total weight of a polymer; the adding amount of the silane coupling agent is 1-5% of the total weight of the polymer; the adding amount of the polyethylene glycol is 0-5% of the total weight of the polymer; and the adding amount of the water is 70-91% of the total weight of the polymer. The manufacturing method disclosed by the invention comprises the following steps: dissolving the polyethylene glycol in a small amount of hot water according to the proportion, then sequentially adding sodium methyl silicate and the silane coupling agent in a stirring state and finally replenishing water till 100%. The methyl silicate stone protecting agent disclosed by the invention has the advantages of waterborne and environment-friendly properties, no toxicity, no volatilization, no pollution, short curing time, stable chemical performances, simplicity, convenience and flexibility in construction and operation, safety and low cost. The methyl silicate stone protecting agent is suitable for waterproofness and moisture-proofness of various natural stones, artificial stones and the like. The methyl silicate stone protecting agent particularly has an excellent waterproof effect on the stones with relatively large holes, such as sandstone, cavity stone and the like, and can simultaneously prevent affecting the air permeability of the stones.

Description

Technical field [0001] The invention relates to a methyl silicate stone protective agent and a manufacturing method. Background technique [0002] As an important building decoration material, stone is increasingly being loved and valued by people. On the one hand, because of its high strength and good other physical and chemical properties, stone is widely used in various fields of construction; on the other hand, due to Its brilliant and colorful colors can meet people's aesthetic requirements in appearance. However, due to the porous nature of the stone itself, the stone is susceptible to many diseases caused by the external environment, which affects the beauty and service life of the stone. Therefore, it is an important step to spray the protective agent on the stone before construction. [0003] Because the stone covers a large area and the protective agent is usually applied in the open air, each protective agent has a certain curing time. Therefore, the curing time of the ...
