Abstract

The invention discloses a foaming material for preparing a functional insole; the foaming material contains 10-98% by mass of an organosiloxane chain segment structure -(Si-O)n-, wherein 1<=n<=5000; the foaming material has an absorption peak near an infrared spectrum of 1080 cm<-1>; the interior of the foam material is a foamed pore structure; the density of the foaming material is 0.05 g / cm<3>-0.90 g / cm<3>. The functional insole is prepared by the foaming material, and all or some parts of the functional insole are prepared by the foaming material. The functional insole has an organosilicone bioinert, can be made into a high opening pore type with the opening rate of 90%, easily absorbs and discharges sweat, allows bacteria not to easily grow and reproduce, and has a good antibacterial effect by self.

Description

technical field [0001] The invention relates to the technical field of insole preparation, in particular to a foam material for preparing functional insoles and the functional insole. technical background [0002] Insoles, this inconspicuous little thing that accompanies us every day, are increasingly valued by people with the development of science and the improvement of living standards. more and more. Therefore, insoles of various materials, styles and functions emerge in an endless stream on the market. [0003] According to the material, it can be divided into six categories: [0004] 1. Various fiber fabrics [0005] Cotton, bamboo fiber, palm fiber, etc. are all used in insoles. The insoles made of these fibers have better hygroscopicity and air permeability, but poor elasticity, which is not conducive to sports, especially the traditional pure cotton insoles. Although it is good, once a person sweats a lot during exercise, the cotton fiber will also expand due to...
