The cable sheath material as one kind of green product contains no halogen, no heavy metal and other environment harming matter, and has high fire retarding performance, high strength and high extensibility.
Description
Technical field:
The present invention relates to the thermoplastic elastomer technical field, especially the application in CABLE MATERIALS.
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, so these obnoxious flavoures and flue gas can constitute a threat to HUMAN HEALTH., 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.
Existing one or both compound low-smoke halogen-free materials of doing with thermoplastic materials such as EVA or PE, PP, 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 novel high flame resistance, low smoke Halogen cable jacket material.
The present invention adopts following technical scheme:
A kind of high flame resistance, low smoke Halogen cable jacket material and complete processing thereof.
The cable sheath main raw material is EPDM, EVA, PP, the acid anhydride-grafted EVA of horse Lay, fire retardant, coupling agent, coumarone tackifying resin, the tenderly white cigarette of ultra micro, carbon black, silicone oil, siloxanes, oxidation inhibitor and environmental protection toner.
EPDM is a terpolymer EP rubber.
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.
Silane coupling agent can be given higher intensity of sizing material and toughness with the synergy of white cigarette.
If do black, then come reinforcement to have better effect with carbon black.
The silica silicon of silicone oil and ultra-high molecular weight helps the interior cunning of sizing material and extrudability.Help improve the surface effect and the glossiness of electric wire, smoothness.
Oxidation inhibitor is antioxidant 1010 and oxidation inhibitor PS802, and the also usefulness of two kinds of oxidation inhibitor can improve the ageing-resistant performance and the flame resistivity of this material.
Its proportioning of cable jacket material main component:
30～60 parts of EPDM
25～40 parts of EVA
10～20 parts of PP
5 parts of the acid anhydride-grafted EVA of horse Lay
110～130 parts of fire retardants
2～6 parts of coupling agents
1～5 part of coumarone tackifying resin
3～5 parts of the tenderly white cigarettes of ultra micro
0～10 part of carbon black
3～10 parts of silicone oil
2～10 parts of siloxanes
1～3 part of antioxidant 1010
0.5～2 part of oxidation inhibitor PS802
3～10 parts of environmental protection toners
Complete processing:
Earlier flame-retardant system and reinforcement system are carried out silane pretreatment, then all raw 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 165 ℃ of first section 165 ℃, second section 175 ℃, the 3rd section 180 ℃, the 4th section 185 ℃, the 5th section 185 ℃ the 6th section 170 ℃, the 7th section 165 ℃, die head temperature; Air-cooled pelletizing.Also available closed plastics processing mill is mixing, extrude granulation with single screw extruder again.Mixing processing temperature is 180 ℃.Extruding temperature is 180 ℃, and die head temperature is 185 ℃, and die face water is cut.
The present invention utilizes three kinds of materials that consistency is splendid, at high temperature adopts the way of fusion mechanical blending, makes their blendings mutually very equably, has complementary advantages, and forms 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 has kept good extrusion performance of EVA and PP and the temperature tolerance of PP, and the elastic snappiness of having given EPDM.Need at distinct colors, adopt black smoke or white cigarette to come this material is carried out reinforcement, can increase the degree of compactness of material, and the extrusion performance and the tensile strength that improve electric wire.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 its advantage is got in heterogeneous blend mutually, and high flame retardant is tested by the VW-1 vertical combustion; The intensity height, good percentage elongation.
