Problems solved by technology

However, the polyurethane material produced by the above method has poor mechanical properties and is not suitable for making shoe soles
[0006] Patent CN110105538A discloses a polyurethane elastomer material for shoe soles. The main material is 75-80 parts of polyester polyol, 7-9 parts of chain extender, 35-40 parts of MDI, 0.8-1.3 parts of antioxidant, 0.3- 0.5 parts of catalyst, 4 to 6 parts of modified multi-walled carbon nanotubes, 0.1 to 0.3 parts of organic silicon, 0.2 to 0.4 parts of epoxy soybean oil, and 0.2 to 0.5 parts of sodium stearate. However, the modified Multi-walled carbon nanotubes are carcinogens, which are not conducive to human health and do not meet the requirements of green environmental protection

Description

technical field [0001] The invention belongs to the technical field of polyurethane elasticity, and in particular relates to an environmentally friendly and odorless foamed shoe sole material and a method for preparing the shoe sole. [0002] technical background [0003] Shoes are a necessity for human life, and with the continuous development of human civilization, the types of shoes are also constantly enriched, such as men's leather shoes, women's leather shoes, casual shoes, sports shoes, canvas shoes, chemical shoes, sandals, slippers and safety shoes And other kinds of shoes. [0004] The full name of polyurethane is polyurethane, which is a general term for macromolecular compounds containing repeated urethane groups on the main chain. It is a polymer compound obtained by the interaction of binary or polyvalent organic isocyanates and polyol compounds. According to its physical properties and uses, polyurethane can generally be divided into rigid polyurethane foam, f...
