Abstract
The invention provides a kind of Flame-retardant PET heat-shrinkable T bush, it is prepared from using strengthening flame-retardant PET material as raw material, described enhancing flame-retardant PET material is adopted and is prepared from the following method：Prepare raw material according to following proportioning, PET 60 70 parts by weight of section, the parts by weight of fire retardant 5 10, the parts by weight of antioxidant 13, the parts by weight of toughener 13 add in high-speed mixer and are well mixed, add glass fibre as reinforcing agent；Feed the mixture into double screw extruder and carry out melt blending extrusion, extrusion material strip is water cooled, traction is stretched, pelleter granulation, produces enhancing flame-retardant PET material；Wherein, described fire retardant is the compound of decabromodiphenyl oxide and antimony oxide；Described toughener is the salt copolymer of ethylene butyl acrylate GMA three；4h is dried in described PET sections at 120 DEG C in advance；Described fire retardant and glass fibre dry 1h at 120 DEG C in advance.The present invention has the following technical effect that：There is pyrocondensation performance and enhancing anti-flammability simultaneously.
Description
Technical field
Strengthen Flame-retardant PET heat-shrinkable T bush the present invention relates to one kind, belong to new material technology field.
Background technology
Heat-shrinkable T bush has the specific function that heat is shunk, and more than 98 DEG C of heating is i.e. collapsible, easy to use.Heat-shrinkable T bush
It is a kind of special polyolefin material thermal contraction casing tube, also has and be called EVA materials.It has soft flexible.It is heated（125
Degree）It can shrink, be widely used in the insulation protection of various wire harness, solder joint, inductance, metal tube, the antirust of rod, corrosion protection.
PET heat-shrinkable T bush（Polyester heat-shrink tube）PVC heat is all substantially exceeded from heat resistance, electrical insulation capability, mechanical performance
Heat-Shrinkable Tubings, it is often more important that PET thermal contraction casing tubes have nontoxicity, it is easy to reclaim, murder by poisoning shadow will not be produced to human body and environment
Ring, more meet environmental requirement.
The environmental-protecting performance of PET heat-shrinkable T bush instructs standard higher than European Union RoHs, can reach Sony SS-00259 environmental protection marks
It is accurate.Without cadmium（Cd）, lead（Pb）, mercury（Hg）, Cr VI（CrVI）, PBBs（PBBs）, PBDE（PBBEs/
PBDEs）, Polychlorinated biphenyls（PCB), PCTs（PCT）, polychlorinated naphthalene（PCN）It is electricity Deng 1 grade of environmental management banned substance
The outer cladding of the electronic components such as electrolysis condenser, inductance, high-grade rechargeable battery, toy and medicine equipment, is entirely capable of meeting outlet
It is required that.
There is following weak point in existing PET heat-shrinkable T bush：Function is single, it is impossible to meet the Composite requirement in market.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art part to strengthen Flame-retardant PET heat-shrinkable T bush there is provided one kind.
