Enough improve the temperature resistant grade and mechanical property of product.Technical white oil colorless and odorless in the filling oil；Naphthenic oil has saturated rings
Shape carbon-chain structure has the characteristics that low pour point, high density, high viscosity, has no toxic side effect, and usually can also connect on its ring
Then it is saturated branch, this structure, which makes naphthenic oil not only, has some properties of arene, but also some properties with straight-chain hydrocarbons,
Again since naphthenic oil comes from natural oil, have the advantages that cheap, from the horse's mouth.
Further, the EP rubbers is ethylene propylene diene rubber；The polyphenylene oxide resin is 040 powder of blue star.
Beneficial effect by adopting the above technical scheme is: ethylene propylene diene rubber Good Heat-resistance can be good at simultaneously
Improve scraped finish and product feel；040 powder dispersibility of blue star is good and smell is small, itself having excellent anti-flammability is not fuel wood
Material, can be greatly improved the flame retardant property and scraped finish performance of product.
Further, the compatilizer is at least one of SEBS grafted maleic anhydride, PP grafted maleic anhydride.
Beneficial effect by adopting the above technical scheme is: the compatilizer SEBS grafted maleic anhydride is in inventive formulation body
Its compatibility can be preferably played in system, and the performance of product is obviously improved；PP grafted maleic anhydride in contrast, by
It is higher in PP grafted maleic anhydride hardness, it will affect product itself feel.
Further, the toughener is at least one of metallocene-polyolefin resin, polyolefin elastomer.
Beneficial effect by adopting the above technical scheme is: metallocene-polyolefin resin is to product mechanical property and anti-tear performance
Promotion have very big help, the use of polyolefin elastomer has very big help, the two phase to integral material feel and resilience performance
It is mutually used in combination, effect is best.
Further, the smoke suppressant is any one in triazine, piperazine pyrophosphate and hydrotalcite.
Beneficial effect by adopting the above technical scheme is: triazine is macromolecular carbon forming agent, is had excellent at charcoal effect, drop
Low-smoke, especially cooperation phosphor nitrogen combustion inhibitor, effect are more significant；Piperazine pyrophosphate is the carbon forming agent for having both fire retardation,
