Embodiment 1

[0060] Under stirring, first dissolve 20g of SSOPA and 20g of polyethylene glycol (PEG 6000) in 100ml of hot water at about 60°C, then add 40g of alum, 25g of silane coupling agent KH-550 and 375g of sodium methyl siliconate, After uniformity, adjust the pH value to 7.5 with phosphoric acid, and finally add water to make up to 1000ml.

Embodiment 2

[0062] Under stirring, first dissolve 20g of SSOPA and 20g of polyethylene glycol (PEG 4000) in 100ml of hot water at about 60°C, then add 40g of alum, 30g of silane coupling agent KH-550 and 470g of sodium methyl siliconate, After uniformity, adjust the pH value to 7.5 with phosphoric acid, and finally add water to make up to 1000ml.

Embodiment 3

[0064] While stirring, first dissolve 20g of SSOPA and 20g of polyethylene glycol (PEG 6000) in 100ml of hot water at about 60°C, then add 40g of alum, 25g of silane coupling agent KH-550 and 475g of sodium methyl siliconate, After uniformity, adjust the pH value to 7.0 with phosphoric acid, and finally add water to make up to 1000ml.

Abstract

The invention relates to a water-based organic silicon waterproof agent by taking sodium methylsilanolate as a main raw material, and is particularly suitable for moving penetration waterproof processing of a porous structure, such as bricks, stone materials, concrete, mortar, cement slurry and the like.

Description

field of invention [0001] The invention relates to a water-based silicone waterproofing agent for building materials, in particular to a water-based silicone waterproofing agent with sodium methyl siliconate as the main raw material. Background technique [0002] Concrete and masonry structures often fail to reach the designed service life due to insufficient durability. Factors leading to the deterioration of concrete properties include steel corrosion, freeze-thaw damage, chemical attack and alkali-aggregate reaction. Water plays a very important role in the process of physical damage and chemical attack to which concrete structures are subjected. If cement-based materials are exposed to water, a series of corrosion reactions will occur. Under the action of one or more of these factors, the service life of concrete will be reduced. [0003] The corrosion effect of water on concrete can be divided into four aspects: (1) In the long-term contact with the cement substrate,...
