Abstract
The invention relates to halogen-free flame-retardant thermoplastic polyurethane. The halogen-free flame-retardant thermoplastic polyurethane is prepared from, by weight, 100-200 parts of thermoplastic polyurethane, 10-30 parts of fire retardant, 10-20 parts of antioxygen, 1-10 parts of dispersant, 1-10 parts of anti-dripping agent and 1-5 parts of releasing agent. The halogen-free flame-retardant thermoplastic polyurethane has excellent fire retardancy, and the requirement for extrusion line forming of the modern industry can be completely met through testing.
Description
Technical field
The present invention relates to plastic applications, specifically, the present invention relates to a kind of halogen-free fire retardation thermoplastic polyurethane.
Background technology
Thermoplasticity polyurethane (TPU) hardness range width (60HA-85HD), wear-resisting, oil resistant, transparent, good springiness, it is used widely in fields such as article of everyday use, sports goods, toy, ornament materials, halogen-free flameproof TPU can also replace soft PVC (PVC) to meet the environmental requirement in more and more field, particularly in wires and cables industry.
Reinforcement day by day along with people's environmental consciousness, the safety of electric wire and environmental protection are increasingly paid attention to, discharging substantial amounts of smog, serious corrosive gas and toxic gas during traditional PVC material burning, the electric wire and the associated electrical electric equipment products that do not meet a lot of national requirements have low-smoke, do not produce poisonous gas, without requirements such as halogen flame retardants. The halogen-free flame retardants being currently mainly used is aluminium hydroxide (ATH) and magnesium hydroxide (MH), but it is low to be single use ATH, MH flame retarding efficiency, need a large amount of interpolation to can be only achieved certain flame retardant effect, so will have a strong impact on mechanical property and the processing fluidity of fire proofing.
Summary of the invention
It is an object of the invention to provide a kind of halogen-free fire retardation thermoplastic polyurethane.
In order to realize the purpose of the present invention, the present invention provides a kind of halogen-free fire retardation thermoplastic polyurethane, it is characterized in that, be made up of the raw material of following weight portion: thermoplastic polyurethane 100-200 part, fire retardant 10-30 part, antioxidant 10-20 part, dispersant 1-10 part, anti-dripping agent 1-10 part and releasing agent 1-5 part.
Preferably, halogen-free fire retardation thermoplastic polyurethane of the present invention is made up of the raw material of following weight portion: thermoplastic polyurethane 150 parts, fire retardant 20 parts, antioxidant 15 parts, dispersant 5 parts, anti-dripping agent 5 parts and releasing agent 3 parts.
It is highly preferred that described fire retardant is N-ethyl-4-{4-[3-(piperidin-1-yl)-propoxyl group]-phenoxy group }-piperidines-1-Methanamide.
It is highly preferred that described antioxidant is 2,6-bis-tertiary Ji-4-cresol.
It is highly preferred that described dispersant is sodium polyacrylate.
It is highly preferred that described anti-dripping agent is EBS.
It is highly preferred that described releasing agent is dimethicone.
Halogen-free fire retardation thermoplastic polyurethane of the present invention has the anti-flammability of brilliance, through test, can meet modern industry completely and be extruded into the requirement of line, it is possible to use at relatively high temperatures.
Detailed description of the invention
Below by way of the description of detailed description of the invention, the invention will be further described, but this is not limitation of the present invention, those skilled in the art's basic thought according to the present invention, various modifications may be made or improves, but without departing from the basic thought of the present invention, all within the scope of the present invention.
