Abstract
The invention discloses a formula of an insulating cable jacket encapsulation. Raw materials comprise the following components in parts by mass: 100 parts of natural rubber, 40-50 parts of degradable polylactic acid PLA, 20-30 parts of maleic anhydride grafted polyethylene, 10-15 parts of heat vulcanized silicone rubber, 2-4 parts of a coupling agent, 2-4 parts of sulfur, 4-6 parts of zinc oxide, 2-4 parts of stearic acid, 2-4 parts of rubber operating oil, 10-12 parts of fillers, 0.8-1.2 parts of a flame retardant, 6-8 parts of white carbon black, 2-4 parts of magnesium chloride, 4-6 parts of glass fiber and 3-5 parts of an antioxidant. The encapsulation layer outside the cable produced by the invention is excellent in insulating property and good in elasticity and avoids insulating level dropping caused by copper ion migration; the coupling agent improves the compatibility; the antioxidant controls to prolong or shorten the decompose time of the plastic; the fillers in the cable obviously improve the mechanical properties and strength of the cable; the integral strength of the encapsulation layer is improved while the good mechanical properties and insulating property are maintained; and through a LOCA test, the encapsulation layer can resist a voltage of 3150 Kv/mm for 5 minutes, and the insulating resistance is greater than 2.5 Mohm.
Description
Technical field
The invention belongs to cable sheath material technical field, be specifically related to a kind of insulativity cable sheath encapsulation formulation.
Background technology
Cable, normally by several or several groups of wires, often organizes the line of at least two stranded similar ropes, and often organize between wire and insulate, and be twisted into round a center, whole outside is surrounded by the coating layer of high-insulation.According to different Application Areass, cable coating layer also adopts different materials to make, such as: rubber, plastics, lead, aluminium, pitch, insullac etc.The insulation of prior art cable and sheath adopt degradable plastics, be mainly biodegradable plastic, if base-material is polylactic acid PLA, PVAC polyvinylalcohol, poly-Carbon dioxide PPC, increase suitable Synergist S-421 95, improve electrical property and the physical and mechanical properties of cable, this degradative plastics itself due to its electrical property and physical and mechanical properties lower, insulation and the sheath requirement of cable can not be met.Natural rubber has compared with high elasticity at normal temperatures, is slightly with plasticity, has extraordinary physical strength, hysteresis loss is little, when being repeatedly out of shape, heat-dissipating is low, flexible resistance good; Because being non-polar rubber, so electrical insulation capability is good; Again because there being unsaturated double-bond, so natural rubber is the material that a kind of chemical reaction ability is stronger, light, heat, ozone, radiation, subdue distortion and the metal such as copper, manganese can promote the aging of rubber, not ageing-resistant is the deadly defect of natural rubber, its oil-proofness and solvent resistance very poor, therefore, on the basis of natural rubber, how to improve the performance of cable sheath, be the technical problem to be solved in the present invention.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of insulativity cable sheath encapsulation formulation.
The technical scheme that the present invention takes is:
A kind of insulativity cable sheath encapsulation formulation, it is characterized in that, feed components is composed as follows by mass parts:
Natural rubber 100 parts, degradable poly lactic acid PLA40-50 part, maleic anhydride grafted polyethylene 20-30 part, hot-vulcanized silicone rubber 10-15 part, coupling agent 2-4 part, sulphur 2-4 part, zinc oxide 4-6 part, stearic acid 2-4 part, rubber processing oil 2-4 part, filler 10-12 part, fire retardant 0.8-1.2 part, white carbon black 6-8 part, magnesium chloride 2-4 part, glass fibre 4-6 part, oxidation inhibitor 3-5 part.
Further, described fire retardant is the mixture that antimonous oxide, silicon-dioxide and aluminium hydroxide form according to weight ratio 2:2:5.
Further, described filler is the mixture that ceramics powder and grain slag micro mist form according to weight ratio 2:3.
Further, described coupling agent is the mixture that γ glycidylpropyl trimethylammonium oxosilane and sodium metasilicate form according to weight ratio 2:3.
Further, described oxidation inhibitor is the mixture that dysprosium oxide and Potassium peroxide and methylcellulose gum form according to weight ratio 3:5:1.
Beneficial effect of the present invention is:
The cable outsourcing glue-line excellent insulation performance that the present invention adopts degradable polylactic acid PLA and maleic anhydride grafted polyethylene to coordinate natural rubber compositions to produce, good springiness, composition not because decompositing corrodes and reduces its specific conductivity, exempting copper ion migration makes dielectric level reduce, add coupling agent, inorganic materials and organic materials generation valence bond in insulating material are closed, improve consistency, add oxidation inhibitor, control the resolving time increasing or reduce plastics, add filler, significantly improve mechanical property and the intensity of cable in the cable, outside the good mechanical property of maintenance and insulativity, improve its bulk strength, sulphurated siliastic, the composition such as sulphur and glass fibre makes cable sheath after LOCA test, its proof voltage 3150Kv/mm, 5min passes through, insulation resistance is greater than 2.5M Ω.
