摘要
以丙烯腈–丁二烯–苯乙烯共聚物(ABS)为研究对象,将质量分数为4%的钛白粉着色剂通过注塑成型添加到ABS树脂中,研究钛白粉粒径及晶型对ABS材料着色能力的影响。研究表明:色板最大色差≤0.5,零件最大色差≤0.6,整体色差一致性相当,且Δb对色差影响最大,Δa对色差影响最小;钛白粉粒径在0.32~0.42μm变化时,ABS材料的耐高温性能以及钛白粉的团聚现象无明显差别,但粒径为0.38μm时的抗紫外老化性能优于粒径为0.32μm和0.42μm时的;与锐钛型钛白粉ABS树脂相比,金红石型钛白粉ABS树脂性能较优,具有更好的耐高温和耐紫外老化性能,且钛白粉颗粒团聚现象相对较少。
Using acrylonitrile-butadiene-styrene copolymer(ABS) as research object, the titanium dioxide colorant with mass fraction of 4% was added into the ABS resin by injection molding, the influence of the particle size and crystal form of titanium dioxide on the coloring ability of ABS material was investigated. The results show that the maximum color difference of the color plate is not more than 0.5,the maximum color difference of the part is not more than 0.6, the overall color difference has the same consistency, and Δb has the greatest influence on the color difference, Δa has the lowest influence on the color difference. When the particle size of titanium dioxide changes in 0.32~0.42 μm, there are no obvious difference in the high temperature resistance performance of the ABS material and the aglomeration phenomenon of titanium dioxide. However, when the particle size is 0.38 μm, the ultraviolet aging resistance of ABS material is superior to those of ABS materials when the particle sizes are 0.32 μm and0.42 μm separately. Compared to the ABS resin adding the anatase-type titanium dioxide, the ABS resin adding the rutile-type titanium dioxide has better performance, and has better high temperature resistance and ultraviolet aging resistance, and the agglomeration phenomenon of the titanium dioxide particles is relatively less.
