Abstract

The invention discloses a cement-based waterproof material and a preparation method thereof. The cement-based waterproof material comprises, by weight, 10 parts of Portland cement, 0.05-0.09 part of master batch material, 2-5 parts of potassium silicate, 0.04-0.08 parts of methylcellulose and 12-15 parts of water. The cement-based waterproof material has the advantages of good waterproofing performance, high stability and high practicability, and can be widely applied to the building field, etc. The preparation method has the advantages of simplicity, low production cost and applicability to industrial production.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to a cement-based waterproof material and a preparation method. Background technique [0002] Cement-based waterproof materials are used as building materials, and can be widely used in fields such as airports, sports venues, subways, building constructions, etc. CN200510061934.7 proposes a cement-based permeable crystalline waterproof material and its production process and construction method, which uses cement as the main raw material , the cement content is 50-65% of the total weight, and the remaining components are active materials 5.5-14.5%, methyl cellulose thickener 3.5-8.0%, anhydrous citric acid retarder 2.0-4.5%, ground quartz Sand 20 40%. But the performance is still low. Contents of the invention [0003] The purpose of the present invention is to provide a cement-based waterproof material which has good waterproof performance and is harmless to the human body. Ano...
