| | The Kc(s) and K,(f) values, the fracture toughness of subcritical and unstable crack propagation, of PS and two types of HIPS (HIPS-A, a blend of PS with 10% rubber; HIPS-B, graft polymer of styrene with 6.5% rubber) were determined by using single edge notched samples. The experimental results showed that after limiting the crack length to a narrow range, the linear elastic fracture mechanics may be used to determine the Kc value of HIPS. | | 用单边缺口法测定了聚苯乙烯(PS)和两种橡胶增韧PS(HIPS-A,10%橡胶,机械共混;HIPS-B,6.5%橡胶,接技共聚)裂纹在亚临界和失稳扩展时的断裂韧性K_c(s)、K_c(f)。实验结果表明,在限制裂纹尺寸范围之后,可用一般单边缺口拉伸方法测定橡胶增韧塑料HIPS的断裂韧性。 | | 文摘来源 | | Blectron microscope was used to study the distribution and transfer behaviour of carbonblack ISAF in rubber blcnd BR-CIIR. It was found that most of carbonblack existed in BR phase but very little in CUR phase even though the amount of ISAF filled in the preblenl of BR-CHR was increased to 10 phr. The carbonblack added to CI1R could transfer to BR phase at enough shearing caused by milling. Certain methods can be used to change the distribution of the carbonblack between two phases and modify the properties... | | 用电镜形态学观察,研究了ISAF在BR/CIIR共混胶料中的分配和转移行为及其对共混胶料性能的影响。加入到BR/CIIR(50/50)共混胶料中的炭黑,主要聚集在BR相中;加入到CIIR相中的炭黑,在足够的剪切作用下,大部分将转移到BR相中或BR与CIIR的两相界面上;但加入到BR相中的炭黑,很少转移到CIIR相中。这说明BR对炭黑具有较强的亲和力。采用不同的工艺方法,可改变炭黑在共混胶料中的分配状况。先将全部炭黑加入CIIR中,再与BR共混,可使共混胶料具有较好的性能。 | | 文摘来源 | | The processing technique of plastics filler made of pretreated CaCO_3 and atactie polypropylene,so-called APP master batch,was developed by one of this paper’s authers(Wen)in 1978 In order to popularize this new filler further and utilize it more efficiently,a series of investigations were carried cut.This paper presents one of these series of investigations. Based on analysing a number of experimental data,it is concluded that the Casson equation can be used for describing the relationship between shear st... | | 无规聚丙烯填充母料技术是本文作者之一(文婉元)的重要研究成果。本文通过大量实验数据分析,结论是:Casson 方程可用于描述无规母料的τ-γ关系,修正的 Casson 方程能相当好地预示等规聚丙烯—无规母料等共混体体系的τ-γ关系。同时,提出了等规聚丙烯在加入无规聚丙烯填充母料后加工性能变化甚微的定量表征。 | | 文摘来源 | |   | | << 更多相关文摘 |
