Abstract

The invention discloses a lightweight and hemp addition polyurethane sole. The sole material comprises the following raw materials in parts by weight: 3-4 parts of azodicarbonamide, 0.7-1 parts of polysorbate, 1-2 parts of phosphorous acid, 80-100 parts of polycarbonate diol, 60-70 parts of isophorone diisocyanate, 1-2 parts of an initiator, 0.5-1 parts of dibutyltin dilaurate, 0.1-0.2 part of a color paste, 50-63 parts of a lightweight filler dispersion, and 0.01-0.02 part of p-toluenesulfonic acid. The sole material is light in weight, good in impact resistance, high in wear resistance, andsuperior in overall performance.

Description

technical field [0001] The invention belongs to the field of shoe sole materials, and in particular relates to a lightweight hemp polyurethane shoe sole and a preparation method thereof. Background technique [0002] Polyurethane sole material has the following advantages: [0003] 1. It has the characteristics of softness, warmth, oil resistance, flex resistance, and wear resistance. It is more than 6 times more wear-resistant than rubber. It can adjust the density and hardness in a wide range according to the requirements of use. It can be made into double-color (double-density) double layers. Sole, the lower sole is a micro-foamed high wear-resistant working surface, and the inner sole is elastic foam that is comfortable to wear; [0004] 2. Very light, with a specific gravity of only 0.3-0.8, much lighter than commonly used sole materials. It is more suitable for thick-soled shoes that require impact resistance and anti-perforation. 15% of the world's safety protection ...
