preparation example Construction

[0044] In a second aspect, the present invention provides a method for preparing the above-mentioned environmentally friendly and durable composite foam material, which specifically includes the following steps:

[0045] (1) Add the ethylene vinyl acetate copolymer, ethylene vinyl acetate rubber, ethylene-octene copolymer, filler, zinc oxide and zinc stearate in parts by mass into an internal mixer and knead for 3 to 5 minutes.

[0046] (2) Add the benzene-free crosslinking agent of the above mass parts into the internal mixer and continue mixing for 2 to 3 minutes;

[0047] (3) Add the above-mentioned expandable microsphere foaming agent in parts by mass to the internal mixer and continue mixing for 2 to 3 minutes;

[0048] (4) Granulating the material obtained in step (3), followed by foam molding to obtain an environmentally friendly and durable composite foam material;

[0049] Wherein, in step (1) to step (3), the mixing temperature of the internal mixer is 90°C to 120°C...

Embodiment 1

[0063] The consumption of each raw material is as shown in Table 1 in the present embodiment.

[0064] The preparation method of the composite foam material in this embodiment is: use an internal mixer to mix the raw materials sequentially, the mixing temperature is 90°C-120°C, the rotating speed of the internal mixer rotor is 40-70 rpm, During the refining process, ethylene-vinyl acetate, ethylene-vinyl acetate rubber, ethylene-octene copolymer, zinc stearate, zinc oxide and fillers are first added to the internal mixer for mixing. The mixing time is 3 to 5 minutes, after mixing evenly, add the crosslinking agent, mix for 2 to 3 minutes, then add the expandable microsphere foaming agent, adjust the rotor speed of the internal mixer to 30 to 40 rpm, and mix for 2 to 3 minutes Discharging, granulation after banburying, followed by foam molding to obtain environmentally friendly and durable foam material pellets.

Embodiment 2 to Embodiment 7

[0066] The consumption of each raw material in embodiment 2 to embodiment 7 is as shown in table 2.

[0067] The preparation methods of the composite foam materials in Examples 2 to 7 are the same as those in Example 1, the only difference being that the dosage of each raw material is adjusted accordingly according to Table 2.

Abstract

The invention provides an environment-friendly durable composite foam material. The foam material is prepared from the following raw materials in parts by mass: 20-40 parts of ethylene vinyl acetate copolymer, 20-40 parts of ethylene vinyl acetate rubber, 10-35 parts of ethylene-octene copolymer, 1-3 parts of benzene-free crosslinker, 5-20 parts of filler, 1-5 parts of expended microsphere foamingagent, 3-6 parts of zinc oxide and 1-5 parts of zinc stearate. The invention further provides a method for preparing the composite foam material. The method comprises the steps of mixing and granulating raw materials. The invention provides application of the composite foam material in preparation of shoe soles and the shoe soles prepared by adopting the composite foam material. The environment-friendly durable composite foam material has excellent durability.

Description

technical field [0001] The invention belongs to the technical field of composite foaming materials, in particular, the invention relates to an environmentally friendly and durable composite foaming material and its preparation method and application. Background technique [0002] As consumers' health awareness and demand for sports protection become increasingly prominent, improving the comfort and functionality of shoes has become an inevitable trend in the development of the footwear industry. In order to meet the cushioning performance of the midsole or insole, softer or better shock-absorbing shock-absorbing materials can generally be used. However, most of the foaming materials for soles at present, after long-term or multiple reciprocating compressions, due to the material itself Fatigue resistance decreases and the gas in the cells in the foam material penetrates to the outside of the cell walls, resulting in permanent deformation of the material and hardening of the ...
