Preparation method of composite printing powder
The invention discloses a preparation method of composite printing powder, which comprises the following steps: (1) washing matrix powder with absolute ethyl alcohol, and drying to obtain mixed powder 1; (2) adding a surfactant and/or a silane coupling agent into an ester solvent to obtain a mixture 2; (3) dispersing the mixed powder 1 obtained in the step (1) into the mixture 2 obtained in the step (2), adding acrylic acid at the temperature of 50-80 DEG C until the acrylic acid is uniformly dispersed, adding a binder, and carrying out a cross-linking reaction to obtain a reactant, the reaction atmosphere of the cross-linking reaction being nitrogen or argon atmosphere, and the reaction time being 45-150 min; the mass of the acrylic acid is 0.5-3.0% of the mass of the matrix powder in the step (1), and the mass of the binder is 1-6% of the mass of the matrix powder in the step (1); and (4) cooling the reactant obtained in the step (3) to room temperature, washing and filtering the reactant by using the ester solvent and absolute ethyl alcohol in the step (2), drying and carrying out heat treatment to obtain the composite printing powder.
本发明公开了一种复合打印粉末的制备方法,步骤为:(1)将基体粉末用无水乙醇洗涤后,烘干,得到混合粉末1;(2)将表面活性剂和/或硅烷偶联剂加入到酯类溶剂中,得到混合物2;(3)将步骤(1)得到的混合粉末1分散到步骤(2)得到的混合物2中,在50‑80℃温度下,添加丙烯酸直至分散均匀后,加入粘结剂进行交联反应,得到反应物,所述交联反应的反应气氛为氮气或氩气气氛,反应时间45‑150min;丙烯酸质量为步骤(1)所述的基体粉末质量的0.5‑3.0%,粘结剂质量为步骤(1)所述的基体粉末质量的1‑6%;(4)将步骤(3)得到的反应物冷却至室温,用步骤(2)所述的酯类溶剂和无水乙醇对所述的反应物进行洗涤过滤后,烘干和热处理,得到复合打印粉末。
