Abstract

The invention discloses a thermochromic TPE (thermoplastic elastomer) material. The thermochromic TPE material is prepared from TPE, polyester staple fibers, epoxy resin, a curing agent, a chromogenic agent, color developing agent, flame retardants and an adhesive. The thermochromic TPE material is high in elasticity, strength and rebound resilience and has a characteristic of availability for injection molding. The thermochromic TPE material can be controlled to realize a thermochromic function at a set temperature through selection of different chromogenic agents and color developing agents, warning of the internal temperature of the material can be realized, and fire accidents can be avoided by warning when the temperature is overhigh; due to addition of the flame retardants, combustion of the material can be prevented in case of inevitable fire, so that loss caused by fire disasters is reduced; by joint use of halogen-free flame retardants and synergistic flame retardants, flame retardation effects are remarkably improved.

Description

technical field [0001] The invention relates to the field of special TPE materials, in particular to a TPE material that develops color when heated. Background technique [0002] Compared with rubber, the more focused meaning of elastomer is a concept of physics and materials science, and its scope is broader. In addition to rubber, elastomers also include many polymer materials with different elastic deformations and diverse cross-linking methods of macromolecular chains. According to whether the elastomer can be plasticized, it can be divided into two categories: thermosetting elastomer and thermoplastic elastomer. Thermosetting elastomers, which are rubber in the traditional sense, and thermoplastic elastomers (Thermoplastic elastomer), abbreviated as TPE, have gradually been used more and more commercially since the 1990s. This classification also shows that these two types of elastomers are processed in two different ways: rubber is processed by thermosetting equipmen...
