AI Technical Summary

Problems solved by technology

[0003] Most of the shoe top materials currently used are polyurethane (PU, TPU) wear-resistant rubber, NBR-type wear-resistant rubber, polyvinyl chloride plastic, etc.; The sky skin needs to be replaced after a few months; at the same time, the sky skin made of these materials will make noise when walking with the ground due to its high hardness; therefore, a new type of sky skin material with good wear resistance and low noise is developed The skin is very important
Some researchers tried to improve the wear resistance of the top skin by improving the traditional rubber mixing process, but the effect was minimal

Embodiment 1

[0014] Take by weighing polyurethane resin 300g; Nylon resin 70g; Butyl rubber 50g; Carbon black 100g; ABS resin 10g; Inject the mold at 200 degrees to obtain a skin with a contact area of ​​2.3 square centimeters, and use a skin abrasion tester to carry out the friction test. The wear thickness of 100 times of friction is 207 microns; the hardness measured by the Shore hardness tester is 55.

Embodiment 2

[0016] Weigh 200g of polyurethane resin; 100g of nylon resin; 30g of butyl rubber; 50g of carbon black; 1g of ABS resin; 1 cm sky skin, using the skin abrasion tester to carry out the friction test, the wear thickness of 100 times of friction is 220 microns; the hardness measured by the Shore hardness tester is 43, which is basically the same as the performance of the pre-mixed and extruded sample.

Embodiment 3

[0018] Take by weighing polyurethane resin 700g; Nylon resin 50g; Butyl rubber 20g; Carbon black 150g; ABS resin 50g; Silane coupling agent 0.5g; For a sky skin of square centimeters, a friction test was carried out using a sky skin wear-resistant testing machine. The wear thickness of the prepared sample after 100 frictions was 189 microns; the hardness was 48.

Abstract

The invention discloses a composite for manufacturing heel lifts and a preparation method of the composite and belongs to the technical field of material preparation. The composite is high in wear resistance, soft, noiseless and fine in corrosion resistance and used for the heel lifts of shoes. The composite is formed by components including, by weight, 20-70 parts of polyurethane resin, 5-35 parts of nylon resin, 1-25 parts of butyl rubber, 5-20 parts of wear-resistant filler, 0.05-5 parts of ABS (acrylonitrile butadiene styrene) resin and 0.01-1 part of coupling reagent. The preparation method of the composite includes the following steps of firstly, weighing the components according to the weight; secondly, uniformly mixing the weighed components according to a certain proportion; and thirdly, forming the heel lift products in an injection molding manner on an injection molding machine after mixing.

Description

technical field [0001] The invention relates to a material, specifically, a composite material used for making sky skins. The invention also discloses a preparation method of the composite material, which belongs to the technical field of material preparation. Background technique [0002] Leather shoes are a basic necessity in people's life, and the part of the heel of the sky leather shoe that directly contacts the ground is an important part of leather shoes (especially ladies' high-heeled shoes). Its wear resistance, elasticity, and corrosion resistance directly affect the wearing comfort of leather shoes and service life. [0003] Most of the shoe top materials currently used are polyurethane (PU, TPU) wear-resistant rubber, NBR-type wear-resistant rubber, polyvinyl chloride plastic, etc.; The sky skin needs to be replaced after a few months; at the same time, the sky skin made of these materials will make noise when walking with the ground due to its high hardne...
