Problems solved by technology

[0002] Generally speaking, the greater the resilience of the soles of sports shoes, the easier it is for the user to exercise while wearing the sports shoes. However, when the user performs more strenuous exercise, due to the weight of the human body, the user receives a greater impulse, so , if the soles of sports shoes cannot effectively cushion the shock, it will cause injury to the user when the user is exercising vigorously. The foam material is necessary

Abstract

The invention discloses a high-cushioning-performance composite foam material and a preparation method thereof. The high-cushioning-performance composite foam material comprises, in parts by mass, 20-40 parts of an ethylene-vinyl acetate copolymer, 10 to 15 parts of polyolefin thermoplastic elastomer, 5 to 15 parts of modified polypropylene, 10 to 20 parts of polyester elastomer, 15 to 30 parts ofnatural latex, 0.3 to 0.5 part of a surfactant, 0.5 to 0.8 part of a borate coupling agent, 0.1 to 0.3 part of a cross-linking aid, 0.7 to 1.2 parts of a cross-linking agent and 2.5 to 3.5 parts of afoaming agent. The composite foam material provided by the invention has good rebound resilience and cushioning property, and is suitable for wide application.

Description

technical field [0001] The invention relates to the field of materials, in particular to a high shock-absorbing composite foaming material and a preparation method thereof. Background technique [0002] Generally speaking, the greater the resilience of the soles of sports shoes, the easier it is for the user to exercise while wearing the sports shoes. However, when the user performs more strenuous exercise, due to the weight of the human body, the user receives a greater impulse, so , if the soles of sports shoes cannot effectively cushion the shock, it will cause injury to the user when the user is exercising vigorously. The foam material is very necessary. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects or problems in the background technology, and provide a composite foam material with high elasticity and high cushioning property and a preparation method thereof. [0004] To achieve the above object, th...
