Embodiment 1
[0014] Embodiment 1 selects each raw material by following raw material and weight percentage proportioning
[0015]
[0016] The preparation process requirements are as follows:
[0017] Heat stearic acid, sodium carbonate, methyl silicic acid, water, and caustic soda in a reaction kettle at 80-95°C, stir for 2 hours, then add triethanolamine, ammonia water, and stir for 10 minutes, then use a 0.6mm mesh Filter through a sieve to remove lumps, and put the filtrate into a closed plastic bucket to obtain an impermeable early-strength silicone waterproofing agent.
Embodiment 2
[0018] Embodiment 2 selects each raw material by following raw material and percentage by weight proportioning
[0019]
[0020] The preparation process requirements are as follows:
[0021] Heat stearic acid, sodium carbonate, methyl silicic acid, water, and caustic soda in a reaction kettle at 80-95°C, stir for 2 hours, then add triethanolamine, ammonia water, and stir for 10 minutes, then use a 0.6mm mesh Filter through a sieve to remove lumps, and put the filtrate into a closed plastic bucket to obtain an impermeable early-strength silicone waterproofing agent.
Embodiment 3
[0022] Embodiment 3 selects each raw material by following raw material and weight percentage proportioning
[0023]
[0024] The preparation process requirements are as follows:
[0025] Heat stearic acid, sodium carbonate, methyl silicic acid, water, and caustic soda in a reaction kettle at 80-95°C, stir for 2 hours, then add triethanolamine, ammonia water, and stir for 10 minutes, then use a 0.6mm mesh Filter through a sieve to remove lumps, and put the filtrate into a closed plastic bucket to obtain an impermeable early-strength silicone waterproofing agent.

Abstract
The invention relates to an impervious early strength organosilicon waterproof agent and a preparation process thereof. The impervious early strength organosilicon waterproof agent comprises the following raw materials in percentage by weight: 1 to 3 percent of stearic acid, 0.2 to 0.8 percent of sodium carbonate, 7 to 10 percent of methyl silicic acid, 50 to 80 percent of water, 11 to 15 percentof sodium hydroxide, 0.4 to 0.7 percent of triethanolamine and 0.5 to 2.5 percent of ammonia water. Due to the addition of the stearic acid, the methyl silicic acid and the sodium hydroxide which serve as main raw materials and the triethanolamine serving as an auxiliary material, the waterproof agent enhances the early strength and plasticization of concrete and mortar and improves the performance of weather resistance and impermeability pressure further, and has the characteristic of convenience for construction simultaneously. The waterproof agent can be sprayed on surfaces of buildings directly, and also can be used for stirring the concrete and the mortar for water prevention. The composition and the construction of the waterproof agent meet requirements of national environmentally-friendly standards. The preparation process of the waterproof agent comprises simple operating steps, so the large-scale production is convenient, and the waterproof agent can be widely used for the waterproof construction of the surfaces of the buildings, projects, basements, tunnels and water ponds.
Description
technical field [0001] The invention belongs to the technical field of waterproofing agent and its preparation process, and in particular relates to a silicone waterproofing agent capable of forming a waterproof layer and its preparation process. Background technique [0002] Waterproofing agent is a commonly used building waterproofing construction material, but all cement concrete buildings generally have leakage defects. Poor, complex construction, great environmental pollution, difficult to widely popularize and use. [0003] The anti-seepage and early-strength silicone waterproofing agent is formed by the reaction of various additives. It is not only superior to other silicone waterproofing agents in performance, but also the construction operation is extremely simple, the anti-seepage ability is obviously improved, and the early strength of concrete and mortar is remarkable. Improvement, little impact on the environment, is currently more advanced waterproof material....
