Abstract

The invention discloses an enhanced far infrared antibacterial low-temperature thermoplastic material and a preparation method thereof. The enhanced far infrared antibacterial low-temperature thermoplastic material is prepared from the following raw materials in parts by weight: 60 to 80 parts of polycaprolactone, 20 to 30 parts of nanometer far infrared ceramic powder, 10 to 20 parts of modified glass fiber, 5 to 15 parts of a nano-silver antibacterial agent, 20 to 40 parts of modified talcum powder and 8 to 16 parts of diffusion oil. The preparation method of the modified glass fiber comprises the following steps: firstly soaking and washing the glass fiber with a boric acid solution, then putting the soaked glass fiber into an ammonium persulfate solution for soaking so as to moisten the surface, finally adding into a coupling agent for ultrasonic oscillation, and drying to obtain the material. According to the far infrared antibacterial low-temperature thermoplastic material disclosed by the invention, the strength of the material is greatly improved by adding the modified glass fiber, and the material is expected to be developed into a medical fixing material with plasticity and strength. Moreover, the nanometer far infrared ceramic powder added into the low-temperature thermoplastic material can promote blood circulation and shorten curing time; the added nano-silver antibacterial agent can effectively prevent propagation of bacteria, so that the occurrence of secondary diseases is prevented.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to an enhanced far-infrared antibacterial low-temperature thermoplastic material and a preparation method thereof. Background technique [0002] Low-temperature thermoplastic material is a kind of polymer material, which is characterized in that it can be softened and molded into any shape at a relatively low temperature, so it can be used in the medical field. Because low-temperature thermoplastic materials soften at low temperatures, have strong plasticity, have memory functions, are light in weight, have certain strength, are easy to bond, have good X-ray permeability, can be thermoplastically molded many times, and can be reused. Doctors It is easy to operate and can be biodegraded after being discarded. It has been used in orthopedic surgery fixation, radiotherapy positioning, orthopedic braces and rehabilitation braces. The low-temperature thermoplastic material products ...
