Abstract

The invention discloses an organic-inorganic composite water repellent for light heat insulation blocks, which is prepared by uniformly mixing the following raw materials in percentage by mass: polymer emulsion 10.0-60.0, common construction cement 30.0-70.0, dispersant 0.2-2.0, penetrant 0.5-10.0 and defoaming agent 0.1 to 2.0.

Description

Technical field: [0001] The invention relates to an organic-inorganic composite waterproofing agent used for surface treatment of light-weight thermal insulation blocks. The lightweight thermal insulation block treated with the waterproofing agent can have good water permeability resistance and low water absorption rate. Background technique: [0002] At present, although the lightweight thermal insulation blocks used for building envelopes have good thermal insulation performance and durability of the same life as the building, but because of poor water permeability and high water absorption, the thermal insulation performance is remarkable after water absorption. Reduction and other issues, so that its application is greatly limited. However, the commonly used organic water repellents have problems such as high cost or poor water resistance, which make them lose their practicability. Invention content: [0003] In order to overcome the problems of poor water penetratio...
