Study on Mechanical Properties of GF/PVC with CPE and ACR

Abstract

Reinforce the strength of PVC by adding glass fiber, study the mechanical properties of PVC on different contents of glass fiber. With the increasing contents of glass fiber, the tensile and bending strength, impact strength are increased, but the breaking elongation is decreased. In order to further improve the toughness of PVC, do research on how to toughen the GF/PVC alloy, study the influence of CPE and ACR on GF/PVC. Use the method of blending modification of glass fiber, PVC and modifiers, significantly increase the impact strength and breaking elongation while maintaining the strength. Compare the influence of CPE and ACR on GF/PVC properties, make excellent strengthened PVC material.

Super-tough PVC/CPE composites: an efficient CPE network by an MGA copolymer prepared through a vibro-milling process

“…Rigid particles, such as calcium carbonate (CaCO 3 ), 1,2 silica (SiO 2 ), 3,4 and organic halloysite nanotubes, 5 among others, can both toughen and strengthen PVC, but the improvement is limited. A signicant improvement in toughness can be obtained with the addition of elastomers, such as chlorinated polyethylene (CPE), 6,7 acrylonitrile-butadiene rubber (NBR), 8 methyl-methacrylate-butadiene-styrene (MBS), 9 and acrylate core-shell rubber (ACR), among others. The core of ACR is butyl acrylate, which plays a toughening role, and the shell is mainly composed of poly(methyl methacrylate) PMMA, which has good compatibility with PVC.…”
