High-strength gypsum-based self-leveling mortar.
The invention discloses high-strength gypsum-based self-leveling mortar which is characterized by comprising water and powder, wherein the powder comprises the following components in parts by mass: 30 to 40 parts of beta semi-hydrated gypsum, 30 to 40 parts of quartz sand with two different finenesses, 1 to 10 parts of modified perlite, 1 to 10 parts of modified bentonite, 0.1 to 3 parts of nanogypsum whiskers, 0.5 to 5 parts of redispersible latex powder, 0.01 to 0.05 part of hydroxypropyl methyl cellulose ether, 0.05 to 1 part of a water reducing agent, 0.1 to 0.5 part of tartaric acid, 0.01 to 0.1 part of a dispersing agent and 0.05 to 0.20 part of a defoaming agent; the ratio of water to powder is (0.25-0.30):1. The self-leveling mortar has the beneficial effects that the self-leveling material has good mechanical properties and fluidity, and especially has excellent wear resistance and heat preservation and heat insulation properties.
本发明公开了一种高强度石膏基自流平砂浆，其特点是包括水和粉料，其中粉料包括按质量份数计算的以下组份：β半水石膏30‑40份，两种不同细度石英砂30‑40份，改性珍珠岩1‑10份，改性膨润土1‑10份，纳米石膏晶须0.1‑3份，可再分散乳胶粉0.5‑5份，羟丙基甲基纤维素醚0.01‑0.05份，减水剂0.05‑1份，酒石酸0.1‑0.5份，分散剂0.01‑0.1份，消泡剂0.05‑0.20份，水与粉料比为0.25‑0.30:1。本发明的有益效果是该自流平材料具有良好的力学性能和流动性，尤其具有优异的耐磨性和保温隔热性能。
