Abstract

The invention discloses wear-resistant flame-retardant TPU and a preparation method thereof. The wear-resistant flame-retardant TPU is prepared from TPU, modified alginate fiber, epoxy resin, polytetrafluoroethylene, a plasticizer, a curing agent, iron stearate, calcium carbonate and silicone oil. The preparation method comprises the following steps: coating the surface of the modified alginate fiber with the silicone oil, uniformly mixing the TPU, epoxy resin, polytetrafluoroethylene and plasticizer, adding the curing agent, iron stearate and calcium carbonate, continuing mixing, and finallyadding the modified alginate fiber to obtain the wear-resistant flame-retardant TPU. The wear-resistant flame-retardant TPU disclosed by the invention has the advantages of better wear resistance andflame retardance.

Description

technical field [0001] The present application relates to the field of TPU, in particular to a wear-resistant and flame-retardant TPU and a preparation method thereof. Background technique [0002] Thermoplastic polyurethane elastomer rubber is also called TPU, which has a wide range of hardness, wear resistance, oil resistance, transparency and good elasticity. TPU can be reprocessed, and TPU products made of TPU have outstanding bearing capacity, impact resistance and shock absorption performance. [0003] In the related art, in the preparation process of thermoplastic polyurethane elastomer rubber, each raw material is mixed evenly, and then kneaded, so that each colloid (raw thermoplastic polyurethane elastomer), powder (filler) and liquid (silicone oil) raw material are mixed. Smelted into block TPU, the obtained TPU has better mechanical properties. [0004] In view of the above-mentioned related art, the inventor believes that there is a defect that the wear resista...
