Light plastering gypsum dry material and preparation method thereof
The invention discloses a light plastering gypsum dry material and a preparation method thereof. The light plastering gypsum powder comprises following raw materials are in percentage by weight: 50 to80 percent of desulfurized gypsum powder, 5 to 20 percent of an active excitant, 8 to 35 percent of reinforced aggregate, 5 to 20 percent of light aggregate, 0.2 to 0.5 percent of a water-retaining agent, 0.2 to 1.5 percent of a tackifier, 0.03 to 0.1 percent of a stabilizer, 0.01 to 0.2 percent of a retarder and 0.005 to 0.02 percent of a catalytic additive; wherein the viscosity of the water-retaining agent is 40000-200000 mPa*s, and the water-retaining agent is a mixture of hydroxypropyl methyl cellulose ether and hydroxyethyl methyl cellulose ether. The preparation method comprises the following steps: weighing the components, pouring the desulfurized gypsum powder, the active excitant, the water-retaining agent, the tackifier, the stabilizer and the retarder into a stirrer for mixingand stirring, then pouring the reinforced aggregate and the light aggregate into a stirring frame, and finally adding water to obtain the light plastering gypsum. The light plastering gypsum has theadvantages that the water retention rate is high, the operable time of the plastering gypsum is further prolonged, and the bonding strength is improved.
本发明公开了一种轻质粉刷石膏干料及其制备方法。轻质粉刷石膏粉体包括，其原料组分按重量百分数计为：脱硫石膏粉50‑80%，活性激发剂5‑20%，增强骨料8‑35%，轻质集料5‑20%，保水剂0.2‑0.5%，增粘剂0.2‑1.5%，稳定剂0.03‑0.1%和缓凝剂0.01‑0.2%，催化加0.005‑0.02%；保水剂的黏度40000‑200000mPa•s，保水剂为羟丙基甲基纤维素醚和羟乙基甲基纤维素醚的混合物；其制备方法为：称取各组分，并将脱硫石膏粉、活性激发剂、保水剂、增粘剂、稳定剂和缓凝剂倒入至搅拌机内混合搅拌，然后将增强骨料、轻质基料倒入搅拌架内，最后加水，最终得到轻质粉刷石膏。本发明轻质粉刷石膏具有较好的保水率、进一步延长了粉刷石膏可操作时间以及粘结强度提高的优点。
