preparation example Construction

[0051] The embodiment of the present invention provides the preparation method of described low-density foam material for sports shoes, comprising the following steps:

[0052] The components in the material are sequentially kneaded, made and foam-molded to obtain a low-density foam material for sports shoes.

[0053] see figure 1 , figure 1 The process flow chart for preparing the low-density foam material for sports shoes provided by the embodiment of the present invention.

[0054] The embodiment of the present invention first weighs the material, and according to the above-mentioned material formula components and dosage, the peroxide crosslinking agent and the azo foaming agent can be weighed as the first group; the active agent and basic zinc oxide can be used as the second group. The group is weighed; the remaining material components are weighed as the third group.

[0055] In the embodiment of the present invention, the weighed material components are mixed and kne...

Embodiment 1

[0062] Adopt the formula described in Table 1, implement according to the following steps:

[0063] According to the composition and dosage of the above-mentioned material formula, the peroxide crosslinking agent and the azo foaming agent are weighed as the first group; the active agent and basic zinc oxide are weighed as the second group; the remaining material groups The points are called as the third group.

[0064] Pour the third group of materials into the internal mixer first, and turn on the machine, when the temperature rises to 80-85°C, pour the second group of materials, and then pour the first group when the temperature rises to 90-95°C When the temperature rises to 100-105°C, pour out the mixed material.

[0065] Pour the mixed material into the material maker, and adjust the temperature of the first, second, third, and fourth zones to 75, 80, 85, and 90°C respectively. And the screw speed is adjusted to 40-50 rpm, and the cutting speed is adjusted to 15-20 rpm. ...

Embodiment 2～4

[0073] The formulations described in Table 1 were used to prepare according to the steps of Example 1 respectively to obtain foaming materials.

Abstract

The invention provides a low-density foaming material for sports shoes. The low-density foaming material for the sports shoes is prepared through foam-forming a material for one time; the material isprepared from the following components: 20 to 30 parts of linear low density polyethylene, 20 to 50 parts of ethylene vinyl acetate copolymer, 30 to 50 parts of ethylene-octene copolymer, 10 to 20 parts of vinyl methacrylate copolymer, 1 to 3 parts of basic zinc oxide, 1 to 1.2 parts of peroxide crosslinking agent, 5 to 6 parts of azo foaming agent, and 1 to 2 parts of active agent. The inventionprovides a preparation method and application of the foaming material. The material is subjected to the one-time foam-forming process so as to obtain the foaming material with the density being lowerthan 0.1g / cm<3>, so that the mechanical property of the foaming material can be remarkably improved, and the foaming material has remarkable cost and efficiency advantages. The foaming material provided by the invention is low in density, and various mechanical indexes such as the tear strength can meet the national standard specified requirement on sports shoe soles.

Description

technical field [0001] The invention relates to the technical field of footwear products, in particular to a low-density foam material for sports shoes, its preparation method and its application. Background technique [0002] With the continuous improvement of people's living standards, people's attention to physical health has reached an unprecedented height, and more and more people participate in various fitness activities. Among the many fitness activities, running is the most popular way to achieve health, and it is also the most concise and effective way. For sports shoes in running equipment, how to reduce the load during running to the greatest extent has become the frontier field of sports shoes development. [0003] Research by biologists has shown (Chen Peng, Qu Feng, Review of Sports Shoes Science and Technology Progress, Shanxi Sports Science and Technology News 2008 (3)), that during running, the impact force on the knee is about 3 to 5 times that of the body...
