氯化聚乙烯(chlorinated polyethylenc,简称CPE)是聚乙烯经氯化反应后制得的一种新型材料,氯化工艺条件、氯含量和原材料会直接影响产品性能。CPE既是一种塑料改性剂,也是一种性能优良的特种胶。从六十年代国内开始从事CPE的研究以来,经过近三十年的努力,尤其是近一、二十年来由安化院和湖北所分别开发的水相法和气相法氯化工艺的不断完善,氯化聚乙烯在国内已有了很大的发展,在很多行业建立了广泛的市场,应用领域也 相似文献

现在氯化聚乙烯和氯磺化聚乙烯已得到广泛的应用。具有不同氯化度的高压和低压聚乙烯可以制备各种新型的工业聚合物:塑料、弹性体、热塑性弹性塑料、皮革状聚合物、坚硬树脂和玻璃状树脂。另外,由于氯的价格比碳氢化合物的价格低廉,氯化聚乙烯(CPE)是最便宜合成聚合物中的一种。但是,CPE的氯化度对其性能的影响至今研 相似文献

研究了CPE、抗冲ACR在PVC中的热老化性能与光老化性能。结果表明,抗冲ACR热老化性能优于CPE,抗冲ACR配方热老化、光老化性能优于CPE配方。CPE配方热老化、光老化性能随CPE用量的增加呈下降趋势,抗冲ACR用量对配方热老化、光老化性能影响较小。 相似文献

采用熔融共混法制备了丙烯腈-丁二烯-苯乙烯三元共聚物(ABS)/废旧NBR胶粉(WNBRP)复合体系,以氯化聚乙烯(CPE)为增容剂改善其界面相容性,研究了CPE用量对其力学性能和微观结构的影响。结果表明,CPE可显著改善ABS/WNBRP复合体系的综合性能,且CPE含量为18份时,综合力学性能最佳;基体中CPE的存在,一方面可以增强ABS与WNBRP的界面相容性,另一方面可以提高基体ABS的塑性变形能力;FE-SEM研究表明,与ABS/WNBRP复合体系相比,增容TPE的断面形貌较为平整,界面结合较好,力学性能提升显著。 相似文献

Blends of high‐density polyethylene with chlorinated polyethylene: Morphology,thermal, rheological,and mechanical properties 下载免费PDF全文
Blends of high‐density polyethylene (HDPE) with chlorinated polyethylene (CPE) were generated using melt mixing. CPE of two different chlorination contents was used and its amount in the blends was varied from 1% till 30%. The rheological, thermal, mechanical, and morphological properties of the blends were characterized along with miscibility analysis. In general, better mixing of the CPE polymer in HDPE was observed at lower CPE concentration and reduced mixing or immiscibility occurred at higher concentration of CPE. However, the extent of immiscibility was different in both CPE25 and CPE35 systems. The rheological analysis of the data using Cole‐Cole, Han‐Chuang and van Gurp plots confirmed the miscibility of CPE25 blends (except for 30% CPE25 blend at lower frequency) whereas CPE35 blends with 10–30% CPE content were immiscible. Highest increase in the rheological properties (complex moduli) was observed at 2% CPE content. The mechanical properties of the CPE25 blends were superior than the corresponding CPE35 blends especially at higher CPE concentration where effects of immiscibility as well as matrix plasticization played a role. The morphology characterization using TEM indicated change in the crystalline features of the polymer in the case of CPE35 blends. The optical microscopy also confirmed the better mixing of CPE25 polymers in HDPE than CPE35. The CPE25 blends exhibited uniformly dispersed CPE phase which was also confirmed by the rheological analysis. However, the blends of CPE35 with 10% CPE content onwards had significant phase immiscibility. POLYM. ENG. SCI., 54:85–95, 2014. © 2013 Society of Plastics Engineers 相似文献

研究了氯化聚氯乙烯(CPVC)、丙烯腈-丁二烯-苯乙烯共聚物(ABS)和氯化聚乙烯(CPE)三元共混体系的组成与性能之间的关系。结果表明,ABS树脂可以有效降低CPVC/ABS/CPE三元共混体系的平衡扭矩,缩短三元共混体系的塑化时间,改善其流动性;当CPE含量固定、共混体系中CPVC与ABS的质量比为7:3时,共混体系的拉伸强度和缺口冲击强度达到最佳,共混体系具有较好的综合力学性能;随着CPE含量的增加,三元共混体系的缺口冲击强度显著提高,CPE对三元共混体系具有优良的增韧作用,用量以15份为宜。 相似文献

Dynamic mechanical properties of biphasic PVC/CPE polymer blends of different micromorphology were studied. It was revealed that a considerable interaction existed between the polymers involved in the high-impact polymer blends. It was established that the most favorable cold impact strength of the high-impact PVC/CPE alloy was obtained when a structure of mixed morphology had been formed in the course of processing. As indicated by the DMA spectra, more marked plasticizing effect of CPE appeared at a lower thickness of CPE layer among the primary globules, i.e., at a higher extent of wetting the PVC globules by CPE molecules. This phenomenon is manifested by splitting the β-relaxation transition of PVC. 相似文献
