Protective cover material obtained by this method.
Background technology
Pvc material belongs to the not high material of heatproof, the in-car high-voltage line insulated wire gone out by Production of PVC, when
When charging pile Exterior cable and internal fault, electric wire easily because temperature resistant grade, high temperature pressure do not reach requirement produce it is molten
Glue and burn.In order to solve the above problems, the materials such as special phase solvent, toughener need to be increased in the material to improve
The heat resistance of polyvinyl chloride.Traditional long-term temperature resistant grade of electric wire highest prepared by polyvinyl chloride can only achieve 105 DEG C,
Too high or when load is high once electric current, the electric wire extremely easy colloidal sol ftractures and fire occurs, while produces a large amount of
Smog pollutes to the environment of surrounding and the person and property is caused damage.
It is several to be used to produce the material up to ten of new energy in-car high-voltage line Insulation Material currently on the market, but can not be complete
Meet requirement of the high-energy source automobile to Insulation Material.One of which is the polyolefine material being crosslinked through electron accelerator irradiation, another
Kind is the TPE materials being combined with butadiene-styrene rubber, special oil-proof composition, high temperature white oil and a variety of polyolefin and efficient flame-retarding agent
Material.Based on wherein being prepared with cross-linking radiation method, but irradiation apparatus investment is big, and it is dirty to environment to produce substantial amounts of waste water during irradiation
Dye is big, while cost for wastewater treatment is too high, injury of the X ray to operating personnel's body and can not estimate during irradiation.Thermoplastic
Property TPE material point two step method could realize production, and technique is complex, and time-consuming, and product storage period is short.Two step method production
TPE material need to first separate the oil-filled rear standing of butadiene-styrene rubber more than 12 hours, then be blended and be granulated with other auxiliary material, production
Insulation Material heat endurance it is poor, mechanical strength is low, high temperature pressure cracking, or surface has a possibility separated out, substantial amounts of small point
Sub- material separates out the mechanical performance for reducing material, and energy consumption is larger, and performance is extremely unstable, is brought to product quality very big
Unstability.
