Production method of low-temperature plasticized fiber composite material and products thereof

Abstract

The invention discloses a production method of a low-temperature plasticized fiber composite material and a product thereof, and the method comprises the following steps: step 1, adding a polycaprolactone raw material into a drying box, drying the raw material at 30-50 DEG C, and putting a fiber raw material into the drying box, and drying the fiber raw material at 110-130 DEG C; step 2, adding 0.03-0.04% of a cross-linking sensitizer into the dried polycaprolactone raw material, and stirring the raw material in a high-speed stirrer to obtain a polycaprolactone mixture; step 3, mixing the polycaprolactone mixture and the dried fiber raw materials according to a mass ratio of 1:0.4-1:1.2, carrying out high-temperature fusion, and cooling the mixture to obtain a composition sheet; step 4, carrying out radiation crosslinking treatment on the composition sheet to crystallize the polycaprolactone polymer, so as to obtain the low-temperature plasticized fiber composite material with high hardness at normal temperature. The material can be used for manufacturing insoles of high-heeled shoes.

Description

Technical field [0001] The invention belongs to the field of material manufacturing, and specifically relates to a method for producing a low-temperature shaping fiber composite material and its products. Background technique [0002] At present, there are many thermoplastic materials that can not deform at room temperature and have a certain degree of hardness, and soften and deform when heated, and can be shaped according to the shape people need. For example, TPU thermoplastic polyurethane elastomer rubber, TPV thermoplastic vulcanizate, TPO thermoplastic polyolefin, EVA ethylene-vinyl acetate copolymer, TPEE thermoplastic polyester elastomer, the melting temperature of these materials is between 80-120 ℃, but these The shortcomings of materials are that they are not strong enough at room temperature, can not have strong supporting force, and are easy to deform; as the temperature increases, these materials gradually soften, the melting temperature is unstable, and it is diffi...

Problems solved by technology

For example, TPU thermoplastic polyurethane elastomer rubber, TPV thermoplastic vulcanizate, TPO thermoplastic polyolefin, EVA ethylene-vinyl acetate copolymer, TPEE thermoplastic polyester elastomer, the melting temperature of these materials is between 80-120 ° C, but these The disadvantage of the material is that the hardness and strength are not enough at room temperature, it cannot have a strong supporting force, and it is easy to deform; as the temperature rises, these materials gradually soften, and the melting temperature is unstable, so it is difficult to accurately control the melting temperature

[0003] With the improvement of Chinese people's health awareness, it is well known that people often wear high heels to cause physical injuries. Part of the reason why wearing high heels often causes foot deformities and diseases is that it changes the force-bearing surface of the feet, and the entire weight of the human body is concentrated on The position of the first and fifth metatarsals (forefoot) and root bone, and other parts of the sole of the foot are basically not involved in the sharing of pressure, which will easily lead to foot deformities and diseases, and reduce the comfort of high-heeled shoes.
