Title:
HIGH HARDNESS OIL-RESISTANT HEAT-RESISTANT PVC MATERIAL
Document Type and Number:
WIPO Patent Application WO/2021/120884
Kind Code:
A1
Abstract:
Disclosed in the present invention is a high hardness oil-resistant heat-resistant PVC material, comprising the following components in parts by weight: 100 parts of PVC resin, 2-10 parts of thermal stabiliser, 8-15 parts of MBS, 2-15 parts of ACR, 0-10 parts of CPE, 3-15 parts of filler, and 1-5 parts of lubricant; the degree of polymerisation of the PVC resin is 700-1300. The PVC material of the present invention uses PVC resin with a degree of polymerisation of 700-1300, adds several toughening agent materials such as MBS, ACR, and CPE, and is capable of preparing a high hardness oil-resistant heat-resistant PVC material.
