Abstract

The invention relates to a water-emulsion organic silicon waterproof agent by taking alkylalkoxy silane 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-emulsion silicone waterproofing agent for building materials, in particular to a water-emulsion silicone waterproofing agent with alkyl alkoxysilane 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,...
