High-strength high-elasticity polyurethane material for shoe material and preparation method of high-strength high-elasticity polyurethane material

Abstract

The invention discloses a high-strength high-elasticity polyurethane material for a shoe material. The high-strength high-elasticity polyurethane material is prepared from the following raw materials in parts by weight: 70-90 parts of polyester polyol, 30-45 parts of toluene diisocyanate, 10-15 parts of diethyltoluenediamine, 15-25 parts of bamboo charcoal powder, 5-6 parts of chitosan, 1-3 parts of activated carbon, 1-3 parts of sodium alginate, 1-3 parts of gelatin, 10-15 parts of sucrose fatty acid ester, 5-8 parts of a 3% calcium chloride solution, 0.1-0.3 part of honeysuckle flower essential oil, 0.1-0.3 part of radix angelicae sinensis essential oil, 2-4 parts of dibutyltin dilaurate, 3-5 parts of 1,3-propylene glycol, 0.5-2 parts of a blowing agent CFA-A8, 10-20 parts of an acetic acid solution, 0.5-1 part of acetic acid, an appropriate amount of water and an appropriate amount of ethanol. The polyurethane composite has favorable air permeability, and favorable antibacterial and deodorizing efficacies, and has the advantages of high hardness and high elasticity.

Description

Technical field [0001] The invention relates to the technical field of shoe materials, in particular to a high-strength and high-elastic polyurethane material for shoe materials and a preparation method thereof. Background technique [0002] The research on the wearing comfort of footwear products is one of the cutting-edge topics in the field of modern shoemaking. It is an inevitable product of the improvement of people's living standards and has important theoretical and practical significance. As China expands domestic demand, implements consumption stimulus policies, expands the number of the middle class, and accelerates the process of urbanization, consumption and demand for better-quality, fashionable footwear products will also increase steadily. At the same time, high and new technologies are changing with each passing day, and new technologies and new products are emerging one after another, thus promoting the continuous development and updating of new materials. The s...

[0004] Huang Guoqing and others published a study on the properties of in-situ embedded microcapsule flavors, using in-situ polymerization to prepare microcapsules with a flavor content of 32.5%, with a particle size of 1-4 μm. This type of preparation In the process, it is basically necessary to add formaldehyde to form a prepolymer, which cannot meet the requirements of environmental protection
