用硅烷偶联剂将几种常用的无机粒子进行表面处理后与ABS进行共混。通过力学性能、熔体流动速率、维卡软化点等性能的表征,说明各种常用的无机填料对ABS的改性效果。实验结果表明:由于纳米碳酸钙的"小尺寸效应"及"表面效应"等特殊效应,用其填充改性可以得到性价比较好的复合材料。 相似文献

采用PB-g-SAN和SBR-g-SAN两种弹性体粒子分别与SAN树脂熔融共混,制得了一系列ABS树脂,研究了ABS树脂的形态结构和力学性能,结果发现,PB和SBR橡胶粒子均匀地分散在SAN基体中,其径分别为0.28μm和0.05μm左右。力学性能结果表明,在SAN树脂中随着PB-g-SAN含量的增加,ABS的冲击强度不断提高,而SBR小橡胶粒子不能增韧SAN树脂,但当SAN树脂中含有15%的PB-g-SAN共聚物时,随着SBR-g-SAN含量的增加,ABS树脂的冲击强度不断提高,SBR-g-SAN这种小橡胶粒子又表现出良好的增韧作用。 相似文献

利用扫描电镜对原位反应增容技术制各的无机非卤阻燃ABS母粒及材料的界面形态进行了系统研究,考察了无机非卤阻燃剂与ABS树脂间的相容性。结果表明:采用该法制得的无机非卤阻燃ABS材料阻燃剂粒子被基体树脂包覆后均匀地分散在ABS树脂中,很难看出阻燃剂与ABS之问明显的界面,断裂截面显示出韧性断裂的基本特征,无机非卤阻燃剂与ABS良好的相容性是母粒法加工技术和原位反应增容技术共同作用的结果。 相似文献

ABS/蒙脱土纳米复合材料的制备、结构及性能 总被引:1,自引:1,他引:1
将SAN/蒙脱土纳米复合材料与ABS高胶粉熔融共混得到ABS/蒙脱土纳米复合材料。对纳米复合材料的机械性能进行了表征.结果发现蒙脱土的加入一定程度上提高了ABS的杨氏模量和弯曲模量,但冲击强度有明显的降低。采用XRD、TEM和SEM对纳米复合材料的结构进行表征,结果表明在共混过程中,蒙脱土片层的物理特性导致其基本分布在橡胶粒子的表面.甚至造成粒子的变形和破裂;ABS/蒙脱土纳米复合材料在冲击过程中,蒙脱土片层的分散状态导致橡胶粒子不能发生塑性变形,冲击断面呈多孔形态。 相似文献

文章采用丙烯腈-丁二烯-苯乙烯(ABS)/氨基蒙脱土(MMT)进行熔融共混得到不同含量MMT的ABS/MMT纳米复合材料。用扫描电子显微镜、拉伸试验机、冲击试验机研究ABS/MMT的力学性能及断面结构。结果得出:在ABS/MMT纳米复合材料中,随着MMT含量的增加,ABS/MMT复合材料的拉伸强度呈先上升后下降,且当MMT含量在3份时性能较好,缺口冲击强度呈线性下降趋势。ABS/MMT冲击断面中,出现了许多网孔结构,橡胶粒子被蒙脱土的的片层包裹着,不能发生塑性变形,其为ABS/MMT复合材料缺口冲击强度降低的主要原因之一。 相似文献

Chrome-plated acrylonitrile–butadiene–styrene ( ABS) parts with defects in the metal layer were submitted to pickling with hydrochloric and nitric acids and recycled by injection in different proportions with neat ABS. For comparison, samples with neat ABS (ABSn) and ABS submitted to pickling (ABSp) were also injected. The influence of the pickled material on the samples properties was evaluated by chemical, thermal, and mechanical analysis. The injected samples were chrome by conventional process and evaluated by visual inspection, adhesion test, resistance to corrosion, and accelerated aging test, to evaluate the quality of the chrome finish. A gradual darkening of samples and formation of carbonyl groups with the increase in the pickled ABS concentration and little influence on the melt flow index were observed. The samples exhibited one thermal degradation stage similar to ABSn. The increase in the pickled ABS percentage caused a slight increase in glass-transition temperature of polybutadiene phase, and did not influence the tensile properties and hardness of samples, but decreased the impact resistance. After chrome plating, all samples were approved for visual inspection and metal layer adhesion test. Only the sample injected with pickled ABS was reproved in corrosion test, due to the oxidation of the chrome layer. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020 , 137, 48372. 相似文献

In this article, a series of polymer–clay nanocomposite (PCN) materials consisted of commercial thermoplastic ABS matrix and dispersing inorganic organoclay platelets were successfully prepared by melt intercalation through the twin‐roller mixer. The as‐prepared materials in the form of pellet were then shaped by injection‐molding machine and the as‐molded specimens were subsequently examined by chemical characterizations, through Fourier transformation infrared (FTIR) spectroscopy, powder X‐ray diffraction (XRD), and transmission electron microscopy (TEM). Effect of the organoclay on thermal stability, mechanical strength, and surface wettability of PCN materials, in both the form of standard dumbbell shape and pellet, was studied using thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), tensile test, hardness test, and contact‐angle measurements, respectively. © 2005 Wiley Periodicals, Inc.
