Waterproof easy plaster and preparation method thereof
The invention provides waterproof easy plaster and a preparation method thereof, and relates to the technical field of building materials. The waterproof easy plaster is prepared from the following raw materials in parts by weight: 30 to 40 parts of cement, 40 to 45 parts of aggregate, 0.5 to 1 part of redispersible latex powder, 0.5 to 1 part of hydroxypropyl methyl cellulose, 0.5 to 1 part of calcium formate, 0.05 to 0.15 part of starch ether, 0.05 to 0.1 part of water reducing agent, 0.3 to 0.5 part of polyacrylonitrile fiber and 0.1 to 0.2 part of triethanolamine, the aggregate is a mixture of 60-120-mesh quartz sand and 40-70-mesh quartz sand in an equal ratio, the water reducing agent is a naphthalene water reducing agent, and the redispersible latex powder is ethylene-vinyl acetate copolymer fixed powder. The easy plaster contains cement, quartz sand aggregate, redispersible latex powder, hydroxypropyl methyl cellulose, a water reducing agent, polyacrylonitrile fiber and the like in a proper proportion, and the components are matched with one another to play a synergistic effect, so that the endurance capacity and the bonding strength of the easy plaster are improved, and cracks can be effectively prevented.
本发明提供一种防水益胶泥及其制备方法，涉及建筑材料技术领域。该防水益胶泥，包括以下重量份的原料：水泥30‑40份、骨料40‑45份、可再分散乳胶粉0.5‑1份、羟丙基甲基纤维素0.5‑1份，甲酸钙0.5‑1份、淀粉醚0.05‑0.15份、减水剂0.05‑0.1份、聚丙烯腈纤维0.3‑0.5份、三乙醇胺0.1‑0.2份，所述水泥为普通硅酸盐水泥，所述骨料为60‑120目石英砂与40‑70目石英砂等比混合物，所述减水剂为萘系减水剂，所述可再分散乳胶粉为乙烯－醋酸乙烯酯共聚物固定粉末。通过益胶泥中含有合适比例的水泥、石英砂骨料、可再分散乳胶粉、羟丙基甲基纤维素、减水剂、聚丙烯腈纤维等相互配合，发挥协同增效的效果，提高了益胶泥的耐受能力、黏结强度，可有效防止裂纹产生。
