Embodiment Construction

[0030] In order to further explain the technical solution of the present invention, the following will be described in detail in conjunction with the examples.

[0031] A nylon foam shoe material, the nylon foam shoe material comprises the following raw materials by weight percentage:

[0032]

[0033]

[0034] Wherein, nylon blend comprises the raw material of following weight percent:

[0035]

[0036] As a preferred form of the present invention, the nylon is nylon 6, which is also called polyamide 6, and its melting point is low. After blending and modification, it can be compatible with the EVA foaming system, and its strength is better than that of polyamide 6. EVA. The tackifier is the 514D tackifier of DuPont in the United States, and the dispersant EF44 dispersant of Hengshui Sanyuan Materials Trading Co., Ltd., wherein the tackifier can better mix nylon and polypropylene for blending modification .

[0037] As a preferred mode of the present invention, th...

Abstract

The invention relates to a foaming nylon shoe material. The foaming nylon shoe material is prepared from raw materials as follows: EVA (ethylene vinyl acetate copolymer), POE (Polyolefin elastomer), nylon blend, calcium carbonate, a catalyst, a lubricant, a foaming agent, a bridging agent and a coupling agent, wherein the nylon blend comprises raw materials as follows: nylon, a dispersing agent, a tackifier, polypropylene and filler. According to the technical scheme, nylon is added to an EVA foaming system for joint foaming, strength of nylon is better than that of EVA, so that the whole shoe material can be subjected to higher-amplification foaming, and the proportion of the shoe material can be reduced; compared with the traditional EVA foaming system, the proportion can be reduced to 50%, the tensile strength can be increased by about 15%, and elasticity of the shoe material is guaranteed with addition of POE.

Description

technical field [0001] The invention relates to a nylon foam shoe material and a manufacturing method thereof, belonging to the technical field of shoe materials. Background technique [0002] EVA is an environmentally friendly plastic foam material, which has the advantages of good cushioning, shock resistance, heat insulation, and chemical corrosion resistance. It is currently widely used in foam shoe materials. For example, in the Chinese invention patent application with application number 201510219070.0 titled "Environmentally Friendly EVA Foamed Shoe Material and Its Manufacturing Method", the environmentally friendly EVA foamed shoe material is disclosed, and its raw material composition by mass percentage is as follows: Ethylene-vinyl acetate copolymer Bio-based plastics: 10% to 20%; Ethylene-octene copolymer: 5% to 15%; Polyolefin block copolymer: 5% to 15%; Talc powder: 5% ~10%; Stearic acid: 0.3% ~ 0.5%; Zinc stearate: 0.3% ~ 0.8%; Zinc oxide: 0.6% ~ 1.2%; Di-(te...
