Abstract

The invention relates to a flexible fluororubber modified PVC (polyvinyl chloride) cable material for automobile wire harnesses, which is prepared from the following raw materials in parts by weight: 65-70 parts of PVC, 7-8 parts of calcium zinc stabilizer, 40-50 parts of trioctyl trimellitate, 2.5-3 parts of triallyl isocyanurate, 0.2-0.3 part of dicumyl peroxide, 5-6 parts of EVA (ethylene-vinyl acetate), 20-25 parts of hexafluoropropylene-terpolymer rubber, 4-4.5 parts of nano zinc oxide, 2.5-3 parts of hydrogenated styrene-butadiene-styrene, 2-2.5 parts of aluminate coupling agent, 2.4-2.8 parts of zinc diethyl dithiocarbamate, 2.8-3.2 parts of nano zirconium oxide, 1.5-2 parts of methyl bis tetrahydrofuran adipate, 1.2-1.6 parts of xylene, 18-22 parts of thermoplastic polyurethane and 0.8-0.9 part of antioxidant 1010. The cable material can not become white after the wire surface is subjected to mechanical scratch and transport scratch, and has the advantages of favorable flexibility, favorable acid/alkali resistance and excellent mechanical properties.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a fluorine rubber modified PVC cable material for flexible automobile wiring harnesses and a preparation method thereof. Background technique [0002] Thermoplastic polyurethane (TPU) is a kind of elastomer with excellent performance, which has excellent acid and alkali resistance, oil resistance and mechanical properties, and has a wide temperature range. It can be used as a toughening agent or modifier for PVC materials. TPU can also improve the processing fluidity of PVC materials and play a plasticizing effect. However, due to the high price of TPU and poor flame retardancy, its application is limited. PVC has many grades, wide application and low cost, and is an important general-purpose plastic. Mixing and crosslinking TPU and PVC can effectively reduce the cost of TPU, improve performance and expand its application range; on the other hand, the addition of TPU can effectiv...
