Abstract

The invention relates to a PVC cable material, in particular to a PVC cable material resistant to pigment migration. The PVC cable material includes the following components in parts by weight: 100 parts of PVC resin, 5-15 parts of silicone-modified SBS, 25-40 parts of dioctyl azelate, titanate-modified white carbon black 20~35 parts, 0.5~2 parts of ultraviolet absorber, 5~15 parts of nano-titanium dioxide, 3~8 parts of dye, and 1~3 parts of antioxidant. The invention solves the problem that the PVC cable material in the prior art has poor resistance to pigment migration, and the pigment is easily migrated to other plastic products, causing the plastic products to be unusable and affecting their application performance. The present invention has the following beneficial effects: (1) The PVC cable material obtained by the present invention has better pigment migration resistance; (2) The PVC cable material obtained by the present invention will not interact with other resins, affecting the performance of both; (3) The present invention has good low temperature resistance, processability and weather resistance.

Description

technical field [0001] The invention relates to a PVC cable material, in particular to a PVC cable material resistant to pigment migration. Background technique [0002] Polyvinyl chloride, referred to as PVC (Polyvinyl chloride), is a vinyl chloride monomer (vinyl chloridemonomer, referred to as VCM) in peroxides, azo compounds and other initiators; or under the action of light and heat, it can be polymerized according to the mechanism of free radical polymerization. made polymer. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. [0003] The molecular weight of industrially produced PVC is generally in the range of 50,000 to 110,000, with a large polydispersity, and the molecular weight increases with the decrease of the polymerization temperature; there is no fixed melting point, it starts to soften at 80 to 85°C, and becomes viscoelastic at 130°C , 160 ~ 180 ℃ began to change into a viscous flow state; good...
