Abstract
The invention discloses a flame-retardant and oil-resistant thermoplastic elastomer wire and cable material resistant to the temperature of 125 DEG C and a preparing method thereof. The wire and cable material is prepared from a thermoplastic elastomer, a softening plasticizer, polypropylene resin, an oil-resistant modifying agent, a compatilizer, filler, a flame retardant, an antioxidant, a light stabilizer and a lubricant. The thermoplastic elastomer is a mixture of high-molecular-weight SEBS with the mass percent of 20%-40% and phenolic resin vulcanization TPV with the mass percent of 60%-80%. The oil-resistant modifying agent comprises at least one of nitrile rubber, acrylic rubber and a polyurethane elastomer. The deformation rate of the prepared material at the high temperature of 125 DEG C is 18%-23%; meanwhile, after being soaked into IRM903# oil for 168 h at the temperature of 60 DEG C, the change rate of the mechanical performance of the material ranges from 15% to 20%; flame resistance is excellent and is in the 1.6-mm ULV0 level, and the strict requirements of UL62 for a TPE material are met.
Description
Technical field
The present invention relates to electric wire formed material preparing technical field, be specifically related to a kind of heatproof 125 DEG C of Flame-Retardant and Oil-Resistant thermoplastic elastomer electric wire and cable material and preparation method thereof.
Background technology
Present market increases day by day for the demand of electric wire, and simultaneously also more and more harsh for its performance requriements, this accelerates many enterprises, school and the scientific research institution technical research process for electric wire and cable material.Electric wire and cable material is in the past PVC and XLPE these two kinds mainly, but along with people and society are for the growing interest of environmental protection, the use of this traditional raw material of PVC is suffered very large restriction.And this material of XLPE is for many factories, which increase this operation crosslinked, make into product cost and increase considerably.But as the thermoplastic elastomer of " gold rubber " due to its environmental protection, nontoxic, recyclable, obtain in recent years and apply in large quantities.
Thermoplastic elastomer roughly comprises polystyrene type elastomerics, ethylene octane copolymer, dynamic perduren class elastomerics, polyurethane elastomer, polyester elastomer.Polystyrene type elastomerics feel is soft, and cost is low, but its temperature tolerance difference (general <90 DEG C), not oil resistant; Ethylene octane copolymer bending fatigue resistance is excellent, easily processes, but its not oil resistant equally; Dynamic vulcanization class elastomerics oil resistant, temperature tolerance are better than the above two, but can not be met the present market requirement; Polyurethane elastomer has excellent oil resistant, wear resistance, but its temperature tolerance is poor, not water-fast; Polyester elastomer has excellent oil-proofness, and heatproof can reach 110 DEG C, but its hardness is comparatively large, processing temperature narrow range.
Now for heatproof, fire-retardant, oil-proofness wire cable material, on market, existing more corresponding patented technology is open, such as, CN101445630A (the special elastomeric CABLE MATERIALS of soft oil-proof rubber of high strength and preparation thereof), CN103113635A (a kind of Oil-resistant power cable material and preparation method thereof) and CN103571067A (a kind of high strength oil resistant epr cable compound) etc.In above-mentioned patented technology, wire cable material is all the cable material of thermoset and cross-linking type, and owing to having to pass through cross-linking radiation or crosslinked with silicane just can use, this can increase production cost undoubtedly.And above-mentioned in CABLE MATERIALS heatproof flame-retardant all do not carry out modification reinforcement, application also can limit to some extent.And for example in CN104629183A (oil-resistant high-temperature flame-retardant thermoplastic elastomer CABLE MATERIALS and preparation method thereof), formula rate be thermoplastic elastomer 20 ?35 parts, oil resistant properties-correcting agent 5 ?15 parts, polypropylene 5 ?10 parts, compatilizer 1 ?5 parts, extending oil 2 ?6 parts, fire retardant 15 ?25 parts, lubricant 0.2 ?0.6 part, oxidation inhibitor 0.4 ?0.8 part.Owing to employing the material containing halogen in wherein fire retardant and oil resistant properties-correcting agent, make CABLE MATERIALS Halogen, poisonous after burning, not environmentally, serious harm HUMAN HEALTH.
Present outlet American Standard supply lead, charging pile electric wire are for the oil resistant of material, high temperature resistant distortion and fire-retardantly all put forward higher requirement, but current wire cable material can't all meet these requirements, so it is imperative to carry out study on the modification to current base material.
