Problems solved by technology

[0004] However, general thermoplastic polyurethane elastomers do not have flame retardancy, and many existing cables such as cables and optical cables are installed in outdoor environments, and if they are placed in a humid outdoor environment for a long time, they are prone to mold and bacteria. It is easy to mold and grow hair, which greatly reduces the service life of polyurethane

Abstract

The invention relates to the technical field of polyurethane elastomers, in particular to a flame-retardant mould-proof thermoplastic polyurethane elastomer composite material and a preparation methodthereof. The composite material is prepared from, by weight, 25-85 parts of TPU, 3-15 parts of SEBS, 5-70 parts of flame retardant, 1-5 parts of mould-proof agent, 0.5-5 parts of compatibilizer and 0.02-0.1 part of antioxidant. According to the thermoplastic polyurethane elastomer composite material, the raw materials are adopted, the weight ratio of all the raw materials is strictly controlled,and the prepared thermoplastic polyurethane elastomer composite material is excellent in flame retarding effect, good in mould-proof effect, high in strength, good in flexibility, high in elongation at break and excellent in mechanical property.

Description

technical field [0001] The invention relates to the technical field of polyurethane elastomers, in particular to a flame-retardant and anti-mold thermoplastic polyurethane elastomer composite material and a preparation method thereof. Background technique [0002] At present, cables are widely used in the fields of power systems, information transmission, and instrumentation systems. However, the cable covering materials made of traditional polymer material PVC are prone to fire and combustion during use, causing fires. Due to the The chlorine content is as high as 60%, which produces fumes of toxic gases such as hydrogen halides and carbon monoxide during combustion. [0003] Polyurethane elastomer refers to a type of elastomeric polymer containing more carbamate functional groups (NH-CO-O-) on the main chain of the macromolecule. It is a typical multi-block copolymer with wear resistance Good, wide hardness range, high strength, high elongation, large load support capacit...
