Non-Newtonian fluid material for shoe material and preparation method thereof

Abstract

The invention discloses a non-Newtonian fluid material for a shoe material and a preparation method of the non-Newtonian fluid material. The non-Newtonian fluid material is prepared from the followingraw materials in parts by weight: 75-85 parts of methyl silicone oil, 17-23 parts of vinyl silicone oil, 2-3 parts of hydrogen-containing silicone oil, 0.9-1.1 parts of a platinum catalyst, 8.5-11.5parts of white carbon black and 17-23 parts of tapioca flour. When the non-Newtonian fluid material disclosed by the invention is applied to an EVA / TPU supercritical foaming composite material, resilience can be greatly improved, permanent compression set ratio is reduced, therefore, after the EVA / TPU supercritical foaming shoe material uses the non-Newtonian fluid material provided by the invention, and when the shoe material is slightly pressed (namely the shoe material bears small force), the shoe material is soft, large in generated deformation and comfortable to wear, and when the shoe material is heavily pressed (namely the shoe material bears large force), the shoe material is hard, it is guaranteed that deformation is not too large, excessive deformation is effectively prevented, and the appearance is prevented from being distorted or even cannot be recovered.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a non-Newtonian fluid material used for shoe materials and a preparation method thereof. Background technique [0002] With the development of society, people have increasingly diversified functional requirements for footwear, especially higher and higher performance requirements for soles. According to different use environments, the functions and styles of shoes are also various, such as hiking shoes, running shoes, slippers and so on. Hiking shoes require wear-resistant and non-slip soles; running shoes require cushioning and non-slip soles; and indoor slippers are used in wet bathrooms for a long time, which are prone to mold growth, so the soles are required to be antibacterial and anti-mildew. Common sole materials include rubber, PU, ​​EVA, TPR, etc. Among them, EVA has the advantages of good elasticity, light weight, anti-aging, and odor resistance. [0003] Non-Newtoni...

AI Technical Summary

Problems solved by technology

At present, there are rare reports on the research of non-Newtonian fluid materials used in shoe materials.

[0004] The currently used foam shoe materials (rubber, PU, ​​EVA, TPR, etc.) still have the following problems: poor elasticity and unsatisfactory rebound effect. This will easily lead to excessive deformation of the shoe material after being subjected to a large force, so that the shape is distorted, or even unable to recover, which may easily cause foot injuries (such as sprains), or the shoe material is too hard to withstand force (even if it is subjected to a large force) Small rear deformation, poor softness, uncomfortable to wear
