Gypsum powder, preparation method thereof, and application of gypsum powder in sculptures and unfired pottery clay
The invention discloses gypsum powder, a preparation method of the gypsum powder and application of the gypsum powder in sculptures and unfired pottery clay. The gypsum powder comprises the followingcomponents in parts by weight: 70-80 parts of gypsum powder, 15-20 parts of a filler, 0.2-0.5 part of a dispersing agent, 2-5 parts of dispersible latex powder, 5-10 parts of a retarder, 5-10 parts ofmodified starch, 8-12 parts of polyvinyl alcohol (PVA) powder, 1-10 parts of cellulose ether, and 1-2 parts of short glass fibers or 0.1-0.2 part of short chemical fibers. The gypsum powder providedby the invention is slow and adjustable in curing speed, and can be cured in 5-15 days; the cured gypsum powder still has high strength, can be used for shaping, and has good weather resistance and good compatibility with other materials; and the gypsum powder is used for sculptures and unfired clay, replaces sculpture clay and argil, is directly cured, does not need mold turnover, casting and high-temperature firing, protects the environment, reduces sculpture shaping procedures, greatly reduces process steps, shortens a sculpturing period and reduces sculpturing cost.
本发明公开了一种石膏粉及其制备方法以及在雕塑和免烧陶泥中的应用,所述石膏粉包括以下重量份数的组分:石膏粉70~80份、填料15~20份、分散剂0.2~0.5份、可分散性乳胶粉2~5份、缓凝剂5~10份、改性淀粉5~10份、聚乙烯醇PVA粉末8~12份、纤维素醚1~10份、玻璃短纤1~2份或化纤短纤0.1~0.2份。本发明提供的石膏粉,其固化速度慢且可调,5‑15天才固化;且其固化后强度依然较高可用于赋形、耐候性好,与其它材料兼容性好;将该石膏粉用于雕塑和免烧陶泥,替代雕塑泥和陶泥直接固化,不需要翻模、浇铸、高温烧制、保护环境、减少雕塑成型工序、大大减少工艺步骤、缩短雕塑工期、降低雕塑成本。
