High-performance waterproof agent and preparing method thereof
The invention discloses a high-performance waterproof agent and a preparing method thereof. The waterproof agent is made from, by weight, 2-8 parts of trichloromethylsilane, 3-7 parts of sodium hydroxide, 5-10 parts of sodium acetate, 4-9 parts of polyving akohol, 0.2-0.5 part of methylcellulose, 10-20 parts of sodium silicate, 3-8 parts of ferric chloride, and 200-300 parts of water. The method comprises the steps of weighing all the materials according to the weight proportion accurately, and mixing and stirring trichloromethylsilane, sodium hydroxide, sodium acetate and half the water to obtain a solution A; adding polyving akohol and methylcellulose to the rest of water, heating the mixture to 80-90 DEG C, adding the solution A while stirring, and obtaining a solution B after sufficient dissolution; adding sodium silicate and ferric chloride to the solution B in sequence, continuing to stir the mixture to an even state, and cooling the mixture to indoor temperature. The waterproof agent is low in alkalinity and high in waterproof performance.
