Abstract

The invention provides polymer cement waterproof slurry prepared from superfine cement, belonging to the field of building materials. The polymer cement waterproof slurry comprises powder and liquid, wherein the liquid contains 80-100 parts of styrene-acrylic emulsion, 1-3 parts of defoaming agent, 1-3 parts of preservative and 50-150 parts of water by weight; the powder contains 300-350 parts of superfine cement, 150-200 parts of calcium carbonate, 100-150 parts of quartz sand and 0.1-5 parts of aid by weight. The polymer cement waterproof slurry has the effects of avoiding the phenomenon of sand sedimentation and further densifying skeleton structures.

Description

Technical field [0001] The invention relates to a waterproof slurry used in the field of home decoration, in particular to a polymer cement waterproof slurry prepared from ultrafine cement, and belongs to the field of building materials. Background technique [0002] Polymer cement type waterproof materials have been widely used in the field of home improvement and waterproofing. There are three main reasons: 1. Polymer cement type materials have extremely low volatile organic content, no irritating odor, and are suitable for relatively closed home decoration. Waterproof construction environment; 2. Polymer cement waterproof material products are cost-effective, and will not increase the cost of home improvement significantly under the condition of meeting the waterproof requirements of home improvement; 3. Polymer cement waterproof materials have good performance with base and tile facing systems Matching and compatibility, excellent long-term durability, no water seepage, no ho...
