Description

technical field

[0001] The invention belongs to the technical field of polymer materials, and in particular relates to a flame-retardant and antistatic thermoplastic polyurethane elastomer and a preparation method and application thereof. Background technique

[0002] Thermoplastic polyurethane elastomer (TPU) is a type of polyurethane that can be plasticized by heating and has no or little chemical crosslinking in its chemical structure. It has high strength, high modulus, good elasticity, and excellent Wear resistance and good oil resistance, so it is widely used in various fields such as medicine, industry, agriculture, military and so on.

[0003] However, without any treatment, the flame retardant effect and antistatic effect of polyurethane elastomer are poor, and its limiting oxygen index is only about 18%, so it is flammable in the air. TPU materials with flame retardants are required in the fields of wires and cables, electronic appliances, etc., which greatly limi...
