Problems solved by technology

[0005] Due to the relatively low production threshold of waterproof coatings, many small manufacturers and black workshops (accounting for about 80% of the waterproof coatings market) exist without production licenses and technology research and development, resulting in chaos in the waterproof coatings market and worrying quality
There are still few high-quality green and environmental-friendly big-brand products in waterproof coatings, and the prices are relatively high

Abstract

The invention discloses an II-type polymer cement waterproof coating and a preparation method thereof. The coating comprises mixed liquid and mixed powder according to the weight part ratio of 90-110:140-160, the mixed liquid comprises the following raw materials in parts by weight: elastic waterproof emulsion, water, a defoamer and a sterilizing agent according to the weight ratio of 90-110: 8-18: 0.15-0.25: 0.08-0.16; and the mixed powder comprises the following raw materials in parts by weight: 32.5 cement, 800-mesh ground calcium carbonate, 40-120-mesh silica sand and a water reducing agent according to the weight part ratio of 90-110: 90-110: 90-110: 0.8-2. Fifteen physical and mechanical properties of a polymer cement waterproof coating as claimed in an embodiment of the invention totally pass all stipulations of GB / T23445-2009, and are much higher than the national standard, and after the II-type polymer cement waterproof coating is soaked in water, heated and subjected to alkali treatment, the tensile strength, the index of elongation at break, bonding force and anti-permeability actual measurement index are much higher than those of the product in the prior art.

Description

technical field [0001] The invention relates to the technical field of cement coatings, in particular to a type II polymer cement waterproof coating and a preparation method thereof. Background technique [0002] In my long-term research on waterproofing difficulties, I found that the main reason for indoor water leakage is that the waterproof coating is not resistant to long-term foaming, and the main reason for roof water leakage is that although the SBS membrane itself has good waterproof performance, the waterproof mechanism is surface adhesion. Type waterproof, water inlet holes in the grassroots, many seams, hollows, easy to penetrate water; although the waterproof coating has a "rooted" waterproof mechanism that blocks the water inlet channel and treats both symptoms and root causes, and has no seams and hollows, it is not easy to penetrate water . However, most waterproof coatings are not resistant to aging and cannot be used on roofs. It is extremely difficult to m...
