Electric wire materials of the present invention, can be for a long time 150 degree high temperature use down do not have the nonflammable and irradiation of drip phenomenon oil resistant when burning after mechanical and physical performance improve a lot.With high density polyethylene(HDPE) and ethene-vinyl acetate is that base-material adds terpolymer EP rubber and elastomerics POE blend, adds fire retardant, anti-aging agent, lubricant then and under design temperature, plasticates through Banbury mixer, and the forcing machine extruding pelletization evenly adds linking agent then.
Characteristics of the present invention:
1. use base-material and processing aid not halogen-containing, have gas and smog that the mankind's lives and properties are damaged and lose in case presence of fire can reduce.
2. improve fire-retardant index, fire retardation raw material and base-material blend are arranged self, become the anti-drippage of charcoal resist behind the selective combustion and at each stage of burning resistant to elevated temperatures flame retardant that works respectively through introducing.
3. through the blend of different performance base-material, improve owing to improving flame retardant effect and fill the unbalance situation of mechanical-physical index that a large amount of fire retardants cause.
4. this material can make superpolymer linear molecule chain formation tridimensional network through behind the irradiation, thereby improves mechanical-physical, the corrosion-resistant and electrical property of chemistry.
5. adopt high temperature resistant base-material blend, add special usefulness anti-aging agent, it can be used under 150 degree high temperature for a long time.
6. the adding lubricant reduces and improves processibility and reduce thermal ageing influence in the course of processing.
7. add terpolymer EP rubber and improve the product oil-proofness.
8. raw material becomes half plastifying state behind Banbury mixer, behind the single screw extrusion machine extruding pelletization, puts into jar spray linking agent that shakes of heating then.
The technical scheme that electric wire materials of the present invention are taked is:
A kind of electric wire materials are characterized in: the electric wire materials comprise following material, and the parts by weight that material is formed are EVA 100-120 part; PE 18-24 part, terpolymer EP rubber 10-15 part, POE 52-58 part; PPO 7-10 part, silicone 0.6-0.9 part, TAIC 3-4 part; Marinco H 200-250 part, zinc borate 8-12 part, PE-g-MAH 28-32 part.
