Abstract
The invention discloses a flame-retardant PVC insulating cable sheath. The flame-retardant PVC insulating cable sheath is characterized by comprising the following components in parts by weight: 100 parts of PVC resin, 30-40 parts of ethylene-propylene methylene copolymer, 12-15 parts of chlorosulfonated polyethylene, 6-8 parts of alkoxyl polydimethylsiloxane, 4-6 parts of sulfur, 1-2 parts of a vulcanization accelerator, 1-2 parts of a boron-zinc compound stabilizer, 4-6 parts of dioctyl phthalate, 0.3-0.5 part of an ultraviolet light absorber, 2-4 parts of an acid absorbent and 3-5 parts of a filler. The flame-retardant PVC insulating cable sheath is excellent in insulativity and heat resistance, high in tensile strength and favorable in flame retardant property, and can favorably resist chemical medium corrosion and remarkably improve the radiation resistance, and the elongation at break of the flame-retardant PVC insulating cable sheath can be higher than 50 percent after the radiological dose reaches 2,400 KGy.
Description
Technical field
The invention belongs to cable sheath technical field, be specifically related to a kind of flame-proof PVC cable insulation jacket.
Background technology
Polyvinyl chloride (PVC) has excellent mechanical property and electrical insulation properties, therefore occupies great advantage at cable industry.Along with countries in the world and respectively organize attention to environment protection, domestic and international market also increases further to the demand of environment-friendly cable material.Cable for wind power generation is due to maintenance difficult, and working conditions is harsh, thus cable performance and life requirements higher, cable is constantly reversed in operational process simultaneously.At present, what the use of cable sheath rubber was many is natural rubber and butadiene-styrene rubber, and this kind of cable sheath rubber elasticity is good, but weathering poor performance, easy season cracking in actual use procedure.In addition, existing cable sheath material does not have the oxidation of resistant to chemical media burn into ozone-resistant and resistance to oil corrosion, the performance such as fire-retardant, awaits raising in mechanical propertys such as anti-times change, heat-resisting, anti-ionizing radiation, low temperature resistant, anti scuffing and electrical insulating properties.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of flame-proof PVC cable insulation jacket.
The technical scheme that the present invention takes is:
A kind of flame-proof PVC cable insulation jacket, it is characterized in that, feed components is composed as follows according to weight part:
Polyvinyl chloride resin 100 parts, ethylene propylene rubber 30-40 part, chlorosulfonated polyethylene 12-15 part, alkyloxydimethicone 6-8 part, sulphur 4-6 part, vulcanization accelerator 1-2 part, boron zinc composite stabilizer 1-2 part, o-phthalic acid dibutyl ester 4-6 part, UV light absorber 0.3-0.5 part, acid absorber 2-4 part, filler 3-5 part.
Further, described filler is nano-sized magnesium hydroxide.
Further, described boron zinc composite stabilizer is the mixture that boron nitride and Zinic stearas form according to weight ratio 3:4.
Further, described UV light absorber be 2,4 dihydroxyl benzophenone, the mixture that forms according to weight ratio 2:2:3 of 2-chloromethyl benzimidazole and benzyltriethylammoinium chloride.
Further, described acid absorber is polyethylene wax, 4, and 4 '-thiobis (the 6-tertiary butyl-3-methylphenol) forms according to 1:1 mixture.
Further, described vulcanization accelerator is the mixture that antimony dithiocarbamate and molybdenum dithiocarbamate form according to weight ratio 2:3.
Beneficial effect of the present invention is:
The present invention improves the over-all properties of PVC cable sheath material from recipe determination aspect, the insulativity of the CABLE MATERIALS made and resistance toheat is good and tensile strength is high, adding of filler composition, makes its this material itself have good flame retardant properties; Boron zinc composite stabilizer not only heat-stable time length can meet cable production requirement but also be a kind of environment-friendly stabilizer, cable sheath rubber can be improved the adding of acid absorber and have good resistant to chemical media corrosion, not only meet environmental friendliness and over-all properties but also good CABLE MATERIALS; UV light absorber and oxidation inhibitor have the aging synergistic effect of radioprotective, can significantly improve the radiation resistance of material, and after radiation dose reaches 2400KGy, its elongation at break is greater than 50%.
