Abstract
The invention relates to halogen-free flame-retardant thermoplastic polyurethane which is prepared from the following raw materials in parts by weight: 50-100 parts of thermoplastic polyurethane, 5-20 parts of flame retardants, 1-10 parts of antioxidants, 1-10 parts of dispersing agents, 1-5 parts of anti-dripping agents and 0.1-0.5 part of mould release agents. The halogen-free flame-retardant thermoplastic polyurethane disclosed by the invention has excellent flame retardance and can completely meet the requirement of extruding into lines in modern industry after test.
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) durometer level wide (60HA-85HD), wear-resisting, oil resistant, transparent, good springiness, be used widely in fields such as daily necessities, sports goods, toy, finishing material, halogen-free flameproof TPU can also replace soft PVC (PVC) to meet the environmental requirement in more and more field, especially at wires and cables industry.
Along with the reinforcement day by day of people's environmental consciousness, the safety and environment protection of electric wire is more and more paid attention to, discharge a large amount of smog, serious corrosive gases 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, the not halogen-containing requirement such as fire-retardant.The main halogen-free flame retardants used is aluminium hydroxide (ATH) and magnesium hydroxide (MH) at present, but it is low to be used alone ATH, MH flame retarding efficiency, need a large amount of interpolation just can reach certain flame retardant effect, mechanical property and the processing fluidity of fire retardant material will be had a strong impact on like this.
