Description
Technical field
The present invention relates to the novel environment friendly electric cable material with low smoke and halogen free, it discloses the prescription and the complete processing of the higher fireproofing cable material without halide of a kind of temperature resistant grade.
Background technology:
Answer international environmental protection trend, use the field at a lot of electric wires, PVC will be limited to ban use of in other words, because it can produce obnoxious flavour when burning more flue gas is arranged.When accidents such as presence of fire, these obnoxious flavoures and flue gas can constitute a threat to HUMAN HEALTH.So, much will replace traditional PVC electric wire with low smoke no-halogen wire as household electrical appliances supply lead, netting twine, computer peripheral wire or the like are local.
We were with one or both compound low-smoke halogen-free materials of doing of thermoplastic materials such as EVA or PE, PP in the past, and it is harder that the electric wire of working it out then can seem, do not have elasticity and snappiness, also do not have soft feel.
Summary of the invention
The purpose of this invention is to provide a kind of high flame retardant high-temperature resistant low-smoke halogen-free cable sheath material and worker's technology thereof.
To achieve these goals, the present invention adopts following technical scheme:
High flame retardant high-temperature resistant low-smoke halogen-free cable sheath material, its main raw material are SEBS, white oil, PP, PS, the acid anhydride-grafted SEBS of horse Lay, fire retardant, coupling agent, the tenderly white cigarette of ultra micro, siloxanes, oxidation inhibitor, environmental protection toner.
Above-mentioned fire retardant is a phosphorus-nitrogen containing flame retardant, and it is a kind of fire retardant of environmental protection, can not produce a large amount of cigarettes and obnoxious flavour in burning.
Above-mentioned coupling agent is a silane coupling agent, and its synergy with white cigarette can be given higher intensity of sizing material and toughness.
Above-mentioned oxidation inhibitor is antioxidant 1010 and oxidation inhibitor PS802.
This cable jacket material mainly is grouped into by the one-tenth of following ratio:
SEBS 100
White oil 20～100
PP 0～100
PS 0～20
The acid anhydride-grafted SEBS 5 of horse Lay
Fire retardant 150～350
Coupling agent 3～6
The tenderly white cigarette 3～5 of ultra micro
Siloxanes 4
Antioxidant 1010 1.5
Oxidation inhibitor PS802 0.5
Environmental protection toner 2～10
The complete processing of high flame retardant high-temperature resistant low-smoke halogen-free cable sheath material:
1. it is stand-by earlier flame-retardant system and reinforcement system to be carried out silane pretreatment;
2. preceding four kinds of base-materials being dropped into the powder cylinder in regular turn stirs, treat fully to be mixed even after, with the mixing extruding pelletization of parallel dual-screw machine, processing temperature is 230 ℃ of first section 185 ℃, second section 190 ℃, the 3rd section 200 ℃, the 4th section 210 ℃, the 5th section 220 ℃ the 6th section 220 ℃, the 7th section 220 ℃, die head temperature; Die face water is cut or tie rod is crossed the water pelletizing.
3. with the even back of all raw material stirring parallel dual-screw machine extruding pelletization.165 ℃ of first section 165 ℃, second section 170 ℃, the 3rd section 180 ℃, the 4th section 180 ℃, the 5th section 175 ℃ the 6th section 165 ℃, the 7th section 160 ℃, die head temperature are air-cooled earnestly.
The present invention utilizes the excellent properties of SEBS each side, add two kinds of materials that consistency is splendid, at high temperature adopt the way of fusion mechanical blending, make their blendings mutually very equably, have complementary advantages, form a kind of thermoplastic elastomer that has rigidity and soft feel simultaneously.Do CABLE MATERIALS with it, no matter, all seem very excellent in intensity, feel, still flexibility.It is stretched on the basis of rate at SEBS splendid snappiness and high strength, snappiness, height, adds these two kinds of hard plastomeies of PP and PS, can improve hardness, improves the extrusion performance of compound simultaneously.CABLE MATERIALS of the present invention is environmentfriendly products, and is not halogen-containing, do not contain heavy metal and other environmentally harmful material, and high flame retardant is tested by the VW-1 vertical combustion; The intensity height, unit elongation is fabulous; Temperature resistant grade reaches more than 90 ℃.
