[0057] Correspondingly, the present invention also provides a method for preparing the color-changing composite foam material as described above, comprising the following steps:

[0058] S1. Knead polyolefin elastomer, ethylene vinyl acetate copolymer, olefin block copolymer and process oil modified SEBS to obtain primary mixed material; mix silica gel, zinc oxide, stearic acid, crosslinking agent, photosensitizer Mixing agent and foaming agent to obtain photosensitive materials;

[0059] S2. Mixing the photosensitive material and the primary mixed material to obtain a remixed material;

[0060] S3. The remixed material is sequentially granulated and foamed to obtain a color-changing composite foam material.

Embodiment 1

[0068] Using the formulation components in Table 1, weigh the following components in parts by mass: polyolefin elastomer, ethylene vinyl acetate copolymer, olefin block copolymer, and oil-extended SEBS. These weighed components are placed in a Lena machine for mixing, the mixing time is 8 minutes to 10 minutes, and the temperature is 110-115° C. to obtain the primary mixed material. The following components are weighed in parts by mass: silica gel, zinc oxide, stearic acid, cross-linking auxiliary agent, odorless cross-linking agent, photosensitizing auxiliary agent, and transparent foaming agent. These weighed components are kneaded to obtain a photosensitive material.

[0069] The obtained photosensitive material is added to the material after preliminary mixing, and a twin-screw extruder is used for mixing, the mixing time is 5-7 minutes, and the temperature is 115-118° C. to obtain a remixed material.

[0070] The mixture obtained by kneading again is placed in a granula...

Abstract

The invention provides a color-changing composite foaming material based on an expandable elastomer as well as a preparation method and application of the color-changing composite foaming material, wherein the color-changing composite foaming material is prepared by mixing and foaming a photosensitive composite material, and the photosensitive composite material comprises the following componentsin parts by mass: 20 to 40 parts of a polyolefin elastomer, 15 to 35 parts of an ethylene vinyl acetate copolymer, 15 to 35 parts of an olefin block copolymer, 5 to 18 parts of operating oil modifiedSEBS, 1.5 to 3 parts of silica gel, 0.2 to 1.5 parts of zinc oxide, 0.1 to 0.8 part of stearic acid, and 1-8 parts of a photosensitive auxiliary agent, wherein the photosensitive auxiliary agent comprises a spiropyrane compound, 0.3 to 8 parts of a cross-linking agent, and 1.5-3.8 parts of a foaming agent. The color-changing composite foam material is excellent in damping performance, good in resilience, high in wear resistance and capable of sensing light and changing color, and the strong three-dimensional appearance vision of a product is improved.

Description

technical field [0001] The invention relates to the technical field of foaming materials, in particular to a color-changing composite foaming material based on expandable elastomers, its preparation method and its application in sports shoe soles. Background technique [0002] At present, ethylene vinyl acetate copolymer (EVA) cross-linked foaming system is more commonly used in sports shoe sole materials. However, the existing sole materials only focus on the pursuit of light weight, high resilience, compression resistance, shock absorption and other physical properties, and the appearance of the product only relies on a simple painting process. As the demand for footwear products in the market becomes more and more diverse, the external appearance of existing sole materials is difficult to meet people's requirements for unique product appearance and stereoscopic vision. Contents of the invention [0003] In view of this, the application provides a color-changing composi...
