High-weather-resistance anti-skid foaming shoe sole and preparation method thereof

Abstract

The invention discloses a high-weather-resistance anti-skid rubber foaming shoe sole and a preparation method thereof. Anti-skid patterns are formed on the bottom surface of the foaming shoe sole; the foaming sole is prepared from the following raw materials: natural rubber, brominated butyl rubber, modified starch, polytetrafluoroethylene, clam meal, zinc oxide, zirconium oxide, vinyl glycol ether, a foaming agent, a vulcanizing agent, an accelerant and a stabilizer. Zinc oxide, zirconium oxide and clam meal are limited to be matched, so that the prepared rubber foaming shoe sole is not prone to yellowing in the vulcanization process, and the color of the prepared rubber foaming shoe sole is guaranteed.

Description

technical field

[0001] The invention belongs to the field of preparation of foamed shoe soles, and in particular relates to a highly weather-resistant non-slip foamed shoe sole and a preparation method thereof. Background technique

[0002] Existing rubber soles have disadvantages such as poor wear resistance, low elasticity, insufficient tensile strength, and poor corrosion resistance and weather resistance, making it difficult for rubber soles to be applied to special fields, such as sports shoes, mountaineering shoes, etc., due to their special The use of the shoe requires that the rubber used for the sole should be wear-resistant, tensile, and also require good impact resistance.

[0003] Therefore, be badly in need of developing a kind of rubber material with high elasticity, high wear resistance, tensile strength, compression without being damaged, and corrosion resistance, good wear resistance of weather resistance just seem very necessary. Contents of the invention...

preparation example Construction

[0029] A preparation method for a highly weather-resistant non-slip rubber foam sole, comprising the following steps:

[0030] Step 1: Mix the raw materials other than the foaming agent, vulcanizing agent, accelerator, and stabilizer by weight, and then carry out banburying. After adjusting the temperature to 95°C, heat it for 5 minutes and then turn the material for the first time; continue to heat up to 102 °C, turn the material for the second time; continue to heat up to 108 °C, add foaming agent, vulcanizing agent, accelerator and stabilizer, turn the material for the third time, and pour the material after banburying for 5 minutes to obtain a blend;

[0031] Step 2: Thin the blend on a roller machine until the roller spacing is 1.2mm, and the number of thinning times is 3 times, then adjust the roller spacing to 5mm to produce a sheet, and transport it to the granulator for granulation. Eagerly cut out pellets to obtain foam pellets;

[0032] Step 3, according to the vul...
