Abstract

The invention discloses a polyurethane composite material regenerated from waste polyurethane soles and a preparation process thereof. The polyurethane composite material is prepared from the following raw materials in parts by weight: 170-180 parts of waste polyurethane soles, 10-14 parts of a compatibilizer, 5-7 parts of toluene diisocynate, 2-4 parts of tri(2,4-di-tert-butylphenol) phosphite ester, 4-6 parts of medical stone powder, 6-8 parts of organic silicon, 2-3 parts of ammonium polyphosphate, 12-18 parts of polyisocyanate, 3-5 parts of hybrid polyester polyol, 5-7 parts of dibutyltin dilaurate, 6-8 parts of alkanolamide, 4-5 parts of nano-alumina powder, 2-3 parts of antioxidant TNP, 7-9 parts of aluminum stearate, 8-10 parts of isocyanate, 4-6 parts of zirconium oxide, 9-11 parts of nano montmorillonite and 10-12 parts of additives. According to the invention, on one hand, the recovery problem of the waste polyurethane soles is solved, on the other hand, the raw materials are easy to obtain, the cost is low, the operation is simple, and emission of three wastes is avoided in the production, so as to protect the environment and reduce the production cost, and ensure that the economic benefit and the social benefit are considerable.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a recycled polyurethane composite material utilizing waste polyurethane shoe soles and a preparation process thereof. Background technique [0002] With its excellent physical properties, good processability, excellent chemical resistance and aging resistance, polyurethane has become one of the most widely used polymer materials in the field of application, and its output and application range are constantly expanding. middle. However, with the expansion of production scale and the expansion of application fields, a large amount of waste is generated during the production and use of polyurethane, including a large amount of polyurethane foam used for heat insulation and sofa cushions, waste polyurethane soles, waste polyurethane leather, etc. If these wastes are only disposed of by landfill and incineration, it will not only occupy land, but also pollute the environ...
