preparation example Construction

[0059] An embodiment of the present invention provides a method for preparing a shock-absorbing foam material for sports shoes as described above, comprising the following steps:

[0060] The components in the material are sequentially mixed, granulated and chemically foamed to obtain a shock-absorbing foam material for sports shoes.

[0061] see figure 1 , figure 1 It is a process flow diagram for preparing shock-absorbing foam materials for sports shoes according to an embodiment of the present invention. The embodiment of the present invention first weighs the material. According to the above-mentioned material formula components and dosage, the blowing agent and a part of peroxide can be weighed as the first group; the active agent can be weighed as the second group; The oxide and polymer components are weighed as the third group, and the remaining material components are weighed as the fourth group.

[0062] In the embodiment of the present invention, the weighed mater...

Embodiment 1

[0070] Adopt the formula described in Table 1, implement according to the following steps:

[0071] According to the above-mentioned material formula components and dosage, the blowing agent and a part of peroxide are weighed as the first group; the activator is weighed as the second group; maleic anhydride, remaining peroxide and polymerization components are weighed as the third group The group is weighed, and the remaining material components are weighed as the fourth group.

[0072]Pour the fourth group of materials into the internal mixer first, and turn on the machine, when the temperature rises to 80-85°C, pour the third group of materials, and then pour the second group when the temperature rises to 90-95°C When the temperature rises to 100-110°C, pour in the first group of materials, and finally pour out the mixed materials.

[0073] Pour the mixed material into the material maker, and adjust the temperature of the first, second, third, and fourth zones to 75, 80, 85...

Abstract

The invention provides a shock absorption foaming material for sneakers and a preparation method and application thereof, and the absorption foaming material is prepared by blending and foaming materials comprising the following components in parts by weight: 30-80 parts of a polyester elastomer; 20-40 parts of an ethylene-vinyl acetate copolymer; 20-50 parts of an alpha-olefin thermoplastic copolymer; 10-20 parts of a styrene polymer; 1-2 parts of a grafting agent; 0.7-1.1 parts of a peroxide; 2-5 parts of a chemical foaming agent; 3-3.5 parts of an active agent and 3-6 parts of a polymerization component, and the polymerization component is selected from one or more of styrene, methallyl sulfonate, triallyl isocyanurate and 1,2-polybutadiene. The foaming material provided by the invention has good shock absorption performance and good mechanical property, and can be used as a shoe sole material for the sneakers. According to the method disclosed by the invention, the process flow issaved, and the method has the advantages of cost and efficiency.

Description

technical field [0001] The invention relates to the technical field of footwear products, in particular to a shock-absorbing foam material for sports shoes, its preparation method and its application. Background technique [0002] During long-distance running like a marathon, the athlete's knee joint absorbs the rebound force from the ground for a long time, and the impact generated by this rebound will cause great damage to the athlete's knee joint. At the moment when the athlete's foot hits the ground, if the bottom material of the sports shoes he wears can absorb this impact, it can greatly reduce the damage to the long-distance runner's knee joint and reduce the fatigue of the athlete. Therefore, it is of great value to develop a sports shoe midsole material with shock-absorbing properties for long-distance sports. [0003] Scientists have found that when a polymer material is impacted by an external force, the movement of its internal molecular structure can absorb thi...
