Abstract

The invention discloses a modified bamboo charcoal fiber and rubber composite material, a preparation method therefor and an application of the modified bamboo charcoal fiber and rubber composite material. The composite material is prepared from the following ingredients in parts by weight: 100 parts of natural rubber, cis-butadiene rubber and styrene-butadiene rubber blended rubber, 15-35 parts of modified bamboo charcoal fibers, 1.2-3.3 parts of sulfur, 2.5-4 parts of zinc oxide, 0.9-1.3 parts of stearic acid and 1.2-2 parts of accelerant TMTD. The preparation method comprises the steps of using the natural rubber, cis-butadiene rubber and styrene-butadiene rubber blended rubber as a raw material, carrying out milling and plastifying on the modified bamboo charcoal fibers, processing aids and the blended rubber in mixing and milling procedures of the raw material, and carrying out procedures such as vulcanization, thereby preparing a modified bamboo charcoal fiber containing rubber composite material and products. The composite material and the products thereof, prepared by the method, can serve as a shoe sole material and can meet the requirements of novel shoe soles on light weight and low cost.

Description

Technical field: [0001] The invention relates to the field of materials, in particular to a bamboo charcoal fiber-rubber composite sole material and a manufacturing method thereof. Background technique: [0002] With the rapid development of the footwear industry, sole materials are mainly developed in terms of light weight and environmental protection. Most of the traditional shoe sole materials are prepared by adding inorganic substances to strengthen composite materials. However, the shoe sole materials prepared by this method have disadvantages such as high density and heavy dust pollution during processing, while plant fibers have low density compared to inorganic fillers. The advantages of being biodegradable and easy to recycle can solve the shortcomings in the application process of inorganic fillers. The interface compatibility between plant fiber and sole matrix material and the dispersion of plant fiber in sole material are the bottlenecks that restrict the impro...
