Pasty high-efficiency methyl silanol potassium sodium waterproof agent and preparation method thereof

Abstract

The invention discloses a preparation method for a methyl silanol potassium sodium waterproof agent, which comprises the following steps of: reacting methyl silicate with sodium hydroxide and potassium hydroxide under stirring until heat is released, and adding water with stirring until the mixed solution is transparent. Through the scheme, the pasty high-efficiency methyl silanol potassium sodium waterproof agent is prepared by the simple preparation method of the invention without heating and heat preservation, wherein the active ingredient content of the waterproof agent is high; only a small amount of waterproof agent is required to be added for the waterproofing of inorganic materials; and compared with the conventional products, the waterproof agent is more convenient to transport and use.

Description

technical field [0001] The invention relates to a potassium sodium methyl siliconate waterproofing agent and a preparation method thereof. Background technique [0002] A single sodium methyl siliconate or potassium methyl siliconate aqueous solution (referred to as silicon water) is unstable when the concentration is higher than 30%. Therefore, sodium methyl siliconate or potassium methyl siliconate currently used for waterproofing and moisture resistance can only be made Into a 30% aqueous solution, the active ingredient is low. At the same time, the production process of the existing products is complicated, and the production materials need to be heated and reacted in the reactor and kept warm for several hours before the finished product can be obtained, and the transportation cost of a single sodium methyl siliconate or potassium methyl siliconate aqueous solution is high, and it is waterproof, moisture-proof, and anti-corrosion. The seepage effect is not good. [00...
