Abstract

The invention discloses waterproof high polymer easy plaster, and belongs to the technical field of building materials. Based on the percentage, the waterproof high polymer easy plaster comprises the following raw materials: 40-50 percent of ordinary Portland cement, 30-45 percent of 60-120-mesh quartz sand, 5-20 percent of 40-70-mesh quartz sand, 1.5-3.0 percent of redispersible latex powder, 0.2-0.35 percent of hydroxypropyl methyl cellulose, 0.4-0.8 percent of calcium formate, 0.05-0.15 percent of starch ether, 0.2-0.4 percent of hydrophobing agent, and 0.07-0.12 percent of polypropylene fiber. In general, the waterproof high polymer easy plaster is high in bonding strength, is greatly advantaged in waterproof performance in comparison with the previous easy plaster, and meets the social requirement.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a waterproof polymer cement. Background technique [0002] After the reform and opening up, the rapid development of society and economy is especially manifested in the huge development of high-rise buildings in urban construction, and the quality of buildings has become the focus of attention from all walks of life. [0003] For the pasting and waterproofing of building tiles and stone materials, there are prominent contradictions between the construction side and the owner side. The problems of building facing bricks falling off, water seepage and leakage have seriously affected the healthy development of the construction industry. In order to solve these problems, many cement-based waterproof polymer materials have been used for bonding gaps and the like. At present, there are many waterproof materials and structures developed and used. Generally speaking, they can...
