Problems solved by technology

[0004] At present, 3D printing technology has been applied to the production of sports shoes, which can not only greatly improve the efficiency of production, but also can be tailored according to each user's feet, which has a good market prospect. However, due to the lag in research on 3D printing materials, The available materials on the market are limited, and the soles printed by 3D printing materials still need to be improved in terms of additional functions such as wear resistance, flame retardancy, soft and hard comfort, etc.

Abstract

The invention provides a 3D printing foaming shoe material and a preparation method thereof, and belongs to the technical field of 3D printing materials. The foaming shoe material is prepared from thefollowing raw materials in parts by weight: 80-100 parts of ethylene-vinyl acetate copolymer, 30-40 parts of ethylene-propylene-diene monomer rubber, 40-50 parts of glass fibres, 5-8 parts of a wear-resistant agent, 6-10 parts of a foaming agent, 4-6 parts of gamma-chloropropyl triethoxysilane, 15-20 parts of a flame retardant, 3-5 parts of a flame retardant synergist, 3-5 parts of a lubricatingagent, 3-5 parts of a foaming auxiliary agent and 1-2 parts of an antioxidant; the flame retardant is a layered double hydroxide; the flame retardant synergist is prepared from graphene and isopropyltris(dioctyl pyrophosphate) titanate which are in the weight ratio of (3-4):1. The 3D printing foaming shoe material prepared with the preparation method has relatively high wear resistance, flame resistance, good elasticity and moderate hardness.

Description

【Technical field】 [0001] The invention relates to the technical field of 3D printing materials, in particular to a 3D printing foamed shoe material and a preparation method thereof. 【Background technique】 [0002] 3D printing, also known as rapid prototyping technology, is also called additive manufacturing technology. It does not require traditional tools, fixtures and machine tools, but is based on digital model files, using adhesive materials such as metal powder or plastic Layer printing technology to manufacture objects of any shape. 3D printers can manufacture many items, such as airplanes, pistols, food, human organs, children's toys, etc. 3D printing technology is a major breakthrough in the world's manufacturing technology field in the past 20 years. [0003] At present, 3D printing mainly includes Fused Deposition Modeling (Fused Deposition Modeling, FDM), Selective Laser Sintering (Selective Laser Sintering, SLS), Stereo Lithography Apparatus (SLA), Laminated Ob...
