Problems solved by technology

When the rider transmits the force to the pedals through the cycling shoes, in order to reduce the loss of force, the stronger the hardness of the sole, the higher the efficiency will be. If the sole is elastic or soft, part of the force will be absorbed, then Riders work harder when pedaling

Abstract

The invention discloses a polyamide cycling shoe sole material and a preparation method thereof. The sole material is composed of a polyamide matrix, carbon fibers or glass fibers, a toughening agent,a surface lubricating auxiliary agent, a heat stabilizer and a color master batch or a toner according to a certain proportion; the preparation method comprises the following steps of: adding the rawmaterials into a double-screw extruder according to a certain proportion, melting, extruding, granulating and drying to obtain the sole material. According to the invention, the polyamide cycling shoe sole material is made of polyamide 6, polyamide 66, polyamide 6 / 66, or a mixture of the three, which is a matrix, carbon fiber or glass fiber is taken as a main structural supporting framework, thehardness of the sole material is increased; the density of the sole material is reduced and the comfort degree of the sole material is improved by using the toughening agent; the product meets the required functionality and comfort of the cycling shoe sole material.

Description

technical field [0001] The invention belongs to a cycling shoe sole material and a preparation method thereof, in particular to a polyamide cycling shoe sole material and a preparation method thereof. Background technique [0002] Cycling is a healthy and natural way of sports tourism, which can fully enjoy the beauty of the travel process. The equipment for riding is very simple, a bicycle is equipped with a backpack, wearing cycling shoes and cycling clothes, wearing a cycling helmet, glasses and gloves, and you can travel, which is simple and environmentally friendly. Since the rider needs to transmit power to the pedals through the cycling shoes, the sole of the cycling shoes will directly affect the quality of the rider's riding experience. When the rider transmits the force to the pedals through the cycling shoes, in order to reduce the loss of force, the stronger the hardness of the sole, the higher the efficiency will be. If the sole is elastic or soft, part of the ...
