Problems solved by technology

[0005] The technical problem mainly solved by the present invention is to provide a preparation method of waterproof mortar for the existing waterproof mortar with low cohesive force, low compressive strength, easy deformation under heavy pressure, and short waterproof life. Blast furnace slag and hydrochloric acid solution are mixed and filtered, the filter is calcined, crushed, sieved, heated with methyltriethoxysilane and tributyl phosphate, then vinyl acetate is added dropwise to stir and react, after freezing treatment, filter, and the filter residue is collected for further processing. Drying and sieving, stirring and mixing the sieved particles with Portland cement, hydroxymethyl cellulose, calcium lignosulfonate, etc., to obtain waterproof mortar. The process of the invention is simple and the prepared waterproof mortar has strong adhesion , high compressive strength, easy to form during pouring, and the waterproof mortar itself has permanent waterproof performance, the building surface after pouring with the waterproof mortar of the present invention has excellent waterproof performance, the waterproof life of the building is greatly extended, and is suitable for large-scale promotion and application

Abstract

The invention discloses a method for preparing waterproof mortar, and belongs to the technical field of building waterproof material preparing. The method includes the steps that blast furnace slag and a hydrochloric acid solution are mixed and filtered, the filtered substances are calcined, smashed and sieved, the product, methyl triethoxysilane and tributyl phosphate are heated, then acetic acid vinyl ester is dropwise added, the mixture is stirred, frozen and filtered, filter slag is collected, dried and sieved, sieved particles, portland cement, hydroxymethyl cellulose, calcium lignosulphonate and the like are stirred and mixed, and the waterproof mortar can be obtained. The technology is easy and convenient, the prepared waterproof mortar is high in binding power and pressure resistant strength and easy to form during pouring; the waterproof mortar has the perpetual water resistance, the building surface poured through the waterproof mortar has the excellent water resistance, the building waterproof age limit is greatly prolonged, and the method is suitable for large-scale application and popularization.

Description
