Abstract
Disclosed is a low-odor soft PVC material. The material comprises the following components in parts by weight: 100 parts of a PVC resin, 60-125 parts of a plasticizer, 2-10 parts of a heat stabilizer, 10-50 parts of a filler, 0-2 parts of an antioxidant, 0.02-0.06 parts of a lubricant and 0.5-1 parts of a deodorant. The PVC resin has a degree of polymerization of lower than 1300; and the deodorant comprises nano calcium carbonate and zinc ricinoleate. By selecting a PVC resin with a low degree of polymerization and a deodorant with a high deodorizing efficiency, the low-odor soft PVC material of the present invention reduces odors from the source, has a small overall impact on the appearance and performance of automotive interior parts, and is low in cost and suitable for large-scale production.
