Methyl silicate stone protecting agent and manufacturing method thereof

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 loved and valued by people. On the one hand, due to its high strength and good other physical and chemical properties, stone is widely used in various fields in the construction industry; on the other hand, due to Its gorgeous 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 lesions due to the influence of the external environment, which in turn affects the beauty and service life of the stone. Therefore, it is very important to spray the protective agent on the stone before construction. [0003] Since 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, so the curing time of...
