In order to guarantee the heat sinking function of terminal box, there is technology to propose at junction box body scatterer to be set, it is that the use of scatterer has increased the production cost of terminal box that there is defective in this technical scheme, and is unfavorable for insulation.Also technology proposes, and uses the bilayer structure of metal shell structure, and between two-layer housing vent passages is set.Adopt the design of metal shell and vent passages, although can improve to a certain extent radiating effect, metal heat absorption capacity in the sun can be offset the heat-sinking capability of metal.And can't accomplish completely waterproof and protection against the tide in junction box body Pi ventilation hole design, the life-span of the electric elements in the butted line box is influential.
Summary of the invention
The purpose of this invention is to provide a kind of material for the manufacture of terminal box, the book material can when guaranteeing insulation, have good heat dispersion.Therefore, do not need to provide separately heat abstractor and vent passages and effectively waterproof and protection against the tide for terminal box.
The present invention is achieved by the following technical solutions:
A kind of material for the manufacture of terminal box, its composition includes the polyphenylene oxide of 25-30% by weight percentage, the nylon 66 of 25-30%, the glass fibre of 5-8%, the compatilizer of 2.5-3.5%, the toughner of 3-4.5%, the auxiliary agent of 1-1.5%, the filler of 25-30%; Described filler is the mixture of silicon carbide and aluminum oxide.
Described aluminum oxide accounts for the weight percent 13-40% of filler.
Described auxiliary agent comprises oxidation inhibitor, lubricant and thermo-stabilizer.
The weight ratio of described oxidation inhibitor, lubricant and thermo-stabilizer is 1: 1: 2.
Compatilizer is selected from the PPO-g-MAH that percentage of grafting is 0.8-1.5%, and the polyphenylene oxide grafted maleic anhydride by adding compatilizer, has strengthened the interface compatibility of polyphenylene oxide and nylon 66, realizes the even mixing of each component in the synthetic plastics.
Toughner is selected from the SEBS-g-MAH that percentage of grafting is 0.8-1.5%, and the SEBS grafted maleic anhydride has improved toughness and over-all properties by doping plasticizing agent in synthetic plastics.
The beneficial effect that the present invention compares with prior art is:
By in plastics, adding silicon carbide and the aluminum oxide with good heat conductive performance, effectively realized radiating effect; And this material has good insulating property.
