preparation example Construction

[0039] When the shock-absorbing material does not contain wear-resistant agent and colorant components, the present invention provides a method for preparing the above-mentioned shock-absorbing material, comprising the following steps:

[0040] The first blending of a mixture containing ethylene-vinyl acetate copolymer, ethylene-octene block copolymer, hydrogenated styrene, bromobutyl rubber, nano calcium carbonate, zinc oxide, zinc stearate and stearic acid Refining to obtain the first-grade mixed material;

[0041] Mixing the primary mixing material with a crosslinking agent and a foaming agent for second mixing to obtain a secondary mixing material;

[0042] Carry out kneading on the secondary mixing material to obtain a shock-absorbing material.

[0043]The invention mixes ethylene-vinyl acetate copolymer, ethylene-octene block copolymer, hydrogenated styrene, brominated butyl rubber, nano calcium carbonate, zinc oxide, zinc stearate and stearic acid to obtain a mixture. ...

Embodiment 1

[0068]

[0069] For mixtures containing ethylene-vinyl acetate copolymer, ethylene-octene block copolymer, hydrogenated styrene, brominated butyl rubber, nano calcium carbonate, zinc oxide, zinc stearate and stearic acid in an internal mixer The first mixing was carried out to obtain the primary mixed material; the temperature of the first mixing was raised from room temperature to 95° C. for 8 minutes.

[0070] The primary mixing material was mixed with the crosslinking agent and foaming agent for the second mixing to obtain the second mixing material; the temperature of the second mixing continued to rise to 105° C. for 2 minutes.

[0071] The secondary mixed material is practiced in a practice machine to obtain a shock-absorbing material. The training process is as follows: first thickening once, thickness 3mm, then thinning twice, each time thickness 1mm, thickening once again, thickness 3mm, to obtain shock-absorbing material.

Embodiment 2

[0073] Put the damping material obtained in Example 1 into a single-screw extrusion granulator. The temperature of the die head of the granulator is 75°C, the temperature of the barrel is 70°C, and the particle size is 3mm. The prepared pellets are left at room temperature for more than 2 hours. Put the static granules into a drying barrel to dry for 1 hour at a drying temperature of 45°C.

[0074] Inject the dry shock-absorbing particles into shoe soles in the injection machine: the injection gun of the injection machine is preferably divided into 4 sections, and the temperatures of the four sections are: 80°C, 82°C, 84°C, and 88°C; The piston is divided into 5 steps of continuous and uninterrupted advancement, the injection rate is 15g / s, and the injection pressure from the first to the fourth section is 80bar, 75bar, 70bar, 65bar; the mold temperature of the injection machine: 175°C, vulcanization The time is 450 seconds; the 5 ovens of the injection machine are connected a...

Abstract

The invention provides a vibration-absorption material, which has excellent vibration-absorption performance without needing to set any vibration-absorption structure. An experiment result of the embodiment shows that a shoe sole obtained through the vibration-absorption material provided by the invention has excellent hardness, tension strength, elongation, right-angled tearing strength, specific gravity, wear-resisting property and vibration-absorption performance, and a vibration-absorption performance G value is less than or equal to 35, which is far better than the vibration-absorption performance (45 or higher) of a common shoe sole.

Description

technical field [0001] The invention relates to the technical field of composite materials for shoes, in particular to a shock-absorbing material and a shoe sole obtained therefrom. Background technique [0002] With the improvement of living standards, people's requirements for shoes have been continuously improved, and have changed from simple functions such as cold protection and protection to fashion, lightness and comfort. The continuous emergence of new functional materials for shoes has provided many useful materials for the traditional shoemaking industry, not only triggering new fashion trends, but also providing a guarantee for the development of footwear functionality and comfort. [0003] Shock-absorbing performance means that when the foot is subjected to a strong impact force, the shock-absorbing material or special shock-absorbing components or devices are used to first generate strong resistance on the shoe, consuming most of the energy transmitted from the g...
