Cushion self-leveling rubber powder premix and cushion self-leveling mortar based on same
The invention discloses a cushion self-leveling rubber powder premix and cushion self-leveling mortar based on the same. The premix is prepared by mixing quick-hardening cement, gypsum, redispersiblelatex powder, a water reducing agent, a defoaming agent, a plastic retaining agent, low-viscosity cellulose and a retarder according to a proper ratio. When the cushion self-leveling mortar is prepared from the cushion self-leveling rubber powder premix, the cushion self-leveling mortar only needs to be uniformly mixed with local Portland cement, washed river sand, ground calcium carbonate powderand water, so that the raw material cost and the transportation cost are greatly reduced, and the application of the cushion self-leveling mortar is simpler and more convenient.
本发明公开了一种垫层自流平胶粉预混料及基于其的垫层自流平砂浆，该预混料是由快硬水泥、石膏、可再分散乳胶粉、减水剂、消泡剂、保塑剂、低粘度纤维素、缓凝剂按合适配比混合而成。本发明用垫层自流平胶粉预混料配制垫层自流平砂浆时，只需要与当地的硅酸盐水泥、水洗河沙、重钙粉加水混匀即可，大幅降低了原材料成本和运输成本，使之应用更加简便。
