Abstract

The invention provides an antitarnish crosslinked PVC (Polyvinyl Chloride) material which is prepared from the following components in parts by weight: 100 parts of PVC resin, 20-30 parts of filler, 30-50 parts of plasticizer, 5-15 parts of composite stabilizer, 3-7 parts of flame retardant, 2-6 parts of crosslinking agent and 2-6 parts of processing aid. The invention also provides a preparation process of the antitarnish crosslinked PVC material. The non-toxic composite stabilizer and the processing aid are added to the antitarnish PVC material to obviously improve the optical stability of the PVC material in radiation processing, i.e. colors are unchanged after the material is radiated. The invention has low-cost and environment-friendly raw materials and wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of polymer material modification, and in particular relates to an anti-discoloration cross-linked polyvinyl chloride material and a manufacturing process thereof. Background technique [0002] Polyvinyl chloride (PVC) material is the best material for wire and cable due to its excellent flame retardancy, electrical insulation, and adjustable hardness. However, due to the poor thermal stability of ordinary PVC, low heat distortion temperature, large compression permanent deformation, hardness greatly affected by ambient temperature, and narrow product temperature range, the application of soft PVC has been limited for a long time. Therefore, cross-linking modification is often used to improve heat softening resistance, pyrotechnic resistance and oil resistance. Crosslinking is an important method in plastic modification. Through crosslinking, a three-dimensional network structure is formed inside the materi...
