一种水溶性3D打印支撑材料的制备方法
摘要：
本发明公开了一种水溶性3D打印支撑材料的制备方法，所述水溶性3D打印支撑材料由以下重量份组分构成：聚乙烯醇100份、甘油10～15份、聚乙二醇5～20份、抗氧剂0.5～1份、热稳定剂3～5份；所述制备方法如下：步骤S1，聚乙烯醇、甘油和聚乙二醇物料的混合；步骤S2，物料的干燥；步骤S3，聚乙烯醇、甘油和聚乙二醇、抗氧剂和热稳定剂的再次混合；步骤S4，双螺杆挤出机中进行挤出造粒。本发明水溶性3D打印支撑材料的制备方法简单、制备过程绿色环保、对设备的要求低；原料成本低、来源丰富；制备的水溶性3D打印支撑材料与打印制件制件的粘结性良好；有利于3D打印技术的推广使用。
摘要（英）：

The invention discloses a preparation method of a water-soluble 3D printing support material. The water-soluble 3D printing support material comprises the following components in parts by weight: 100parts of polyvinyl alcohol, 10-15 parts of glycerol, 5-20 parts of polyethylene glycol, 0.5-1 part of an antioxidant and 3-5 parts of a heat stabilizer. The preparation method comprises the followingsteps: S1, mixing polyvinyl alcohol, glycerol and polyethylene glycol materials; step S2, drying the mixed materials; step S3, mixing the mixed polyvinyl alcohol, glycerol and polyethylene glycol withthe antioxidant and the heat stabilizer; and S4, carrying out extruding and granulating in a double-screw extruder. The preparation method of the water-soluble 3D printing support material is simple,the preparation process is green and environmentally friendly, and the requirement on equipment is low; the raw materials are low in cost and have rich sources; the prepared water-soluble 3D printingsupport material has good adhesive property with printed parts; and popularization and application of 3D printing technology are facilitated.
