Gypsum 3D printing powder as well as preparation method and application thereof
The invention provides gypsum 3D printing powder, which is prepared from the following components in percentage by mass: 87.8 to 98.5 percent of commercial alpha gypsum; 0.5%-1% of hydrophobic nano silicon dioxide; 1%-3% of soluble starch; 0%-1.2% of sodium oxalate; 0%-7% of 2488 type PVA (Polyvinyl Alcohol). The invention also provides a preparation method of the gypsum 3D printing powder, which comprises the following steps: step 1, weighing commercial alpha gypsum according to the mass percentage, drying and sieving to obtain gypsum powder; step 2, weighing hydrophobic nano silicon dioxide and soluble starch according to the mass percentage, and barreling and mixing the hydrophobic nano silicon dioxide and the soluble starch with the gypsum powder to obtain first powder; step 3, weighing sodium oxalate according to the mass percentage, and barreling and mixing the sodium oxalate with the first powder to obtain second powder; and step 4, weighing the corresponding amount of 2488 type PVA according to the mass percentage, and barreling and mixing the 2488 type PVA and the second powder to obtain the gypsum 3D printing powder. The invention also provides application of the gypsum 3D printing powder in preparation of a polymorphic pore structure functional material.
本发明提供了一种石膏3D打印粉末，按质量百分比计，包括以下组分：商业α石膏：87.8％～98.5％；疏水性纳米二氧化硅：0.5％～1％；可溶性淀粉：1％～3％；草酸钠：0％～1.2％；2488型PVA：0％～7％。本发明还提供了石膏3D打印粉末的制备方法，包括以下步骤：步骤1，按质量百分比称取商业α石膏，烘干处理后过筛，得到石膏粉体；步骤2，按质量百分比称取疏水性纳米二氧化硅和可溶性淀粉，并与将石膏粉体滚磨混合，得到第一粉体；步骤3，按质量百分比称取草酸钠，并与第一粉体滚磨混合，得到第二粉体；步骤4，按质量百分比称取对应量的2488型PVA，并与将第二粉体进行滚磨混合，得到石膏3D打印粉末。本发明还提供了石膏3D打印粉末在制备多形态孔结构功能化材料上的应用。
