Abstract

The invention discloses polymer cement waterproof coating and a preparation method thereof and relates to the field of building materials. The waterproof coating comprises the following liquid materials: 70-87% of high polymer emulsion, 10-30% of water, 0.4-0.8% of a defoaming agent, 0.5-1% of a dispersing agent, 0.08-0.12% of a wetting agent, 0.5-1% of propylene glycol and 0.1-0.3% of an antiseptic fungicide; and the waterproof coating also comprises the following powder materials: 30-50% of cement, 30-50% of wollastonite in powder, 15-30% of quartz powder, 0.1-0.3% of anhydrous cupric sulfate, 0.2-0.4% of a water reducing agent, 0-0.3% of cellulose ether, 0-2% of high polymer latex powder and 0-0.4% of an organic silicon defoamer, wherein mesh granularities of the wollastonite in powderand quartz powder are 1200-1300 meshes respectively. The waterproof coating disclosed by the invention has basic properties and also has the advantage that a dried film changes color when encounteringwater, and a leakage location of a building can be rapidly, conveniently and accurately detected.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a polymer cement waterproof coating and a preparation method thereof. Background technique [0002] According to the survey, among buildings of different ages, the roof leakage rate of buildings built in and before 2002 is the highest, at 96.12%; the roof leakage rate of buildings built in 2003-2008 is next, at 95.62%. The leakage rate of the roof built in the past 5 years is the lowest, which is 94.29%. Although there is a slight difference in the data, the leakage rate of buildings with different ages exceeds 90%, indicating that the leakage problem has always been very common, the improvement is small, and there are water channeling in many leaking parts. [0003] After the existing building leaks, because the construction has been completed, the leaking part has concealment, and it is difficult to accurately find it. As a result, the leakage point cannot be accurately foun...
