摘要 以甲基丙烯酸甲酯(MMA)、丙烯酸丁酯(BA)及甲基丙烯酸-β-羟乙酯(HEMA)为原料,通过水相悬浮聚合法制备了羟基丙烯酸共聚树脂,并对该共聚树脂进行了傅里叶变换红外光谱分析。将羟基丙烯酸共聚树脂与聚乙烯醇复配作为三维(3D)打印粉末材料,以去离子水作黏结溶液,经3D打印制取柔韧性产品。考察了羟基单体HEMA用量、m(MMA)/m(BA)以及粉末材料的原料配比对产品应用性能的影响,确定了合成共聚树脂的最佳条件及粉末材料的最佳原料配方,并观察了最佳配方条件下制备的3D打印产品的断面形貌。最佳配方条件下,3D打印产品的弯曲强度为9.1 MPa,抗压强度为26 MPa,柔韧性为2 mm,基本满足柔韧性产品3D打印需求。 The hydroxyl acrylic copolymerized resin that would be used with poly(vinyl alcohol) together as prototyping powder with flexibility for three dimensional printing (3DP) was prepared by aqueous suspension polymerization method from methyl methacrylate (MMA), butyl acrylate (BA) and β-hydroxyethyl methacrylate (HEMA), and then was analyzed with Fourier transform infrared spectrometry (FTIR). Afterwards 3DP product was obtained from the prototyping powder and deionized water which was used as adhesive solution. The effects of the dosage of HEMA, the mass ratio of MMA to BA and the ratio of prototyping powder on the properties of the 3DP product were investigated, the optimum synthetic conditions and the optimum ratio of the prototyping powder were determined, and the microtopography of the rupture of the 3DP product under the optimal conditions was observed. The flexural strength, the compressive strength and the flexibility of the 3DP product was 9.1, 26 MPa and 2 mm respectively, which basically met the requirements of application of flexible products to 3DP.
