A light-transmitting foamed shoe sole composition and a method for making shoe soles using the composition

Abstract

The invention relates to a light-transmitting foaming shoe sole composition, which is composed of the following raw materials: magnesium carbonate, white foaming agent, dicumyl peroxide, 2,6-di-tert-butyl-4-formazol phenol or dibutylhydroxytoluene, transparent zinc oxide, stearic acid, trimethylolpropane triacrylate, silane coupling agent, ethylene-vinyl acetate copolymer, olefin block copolymer, ethylene-styrene-butylene Diene tri-block copolymer, ethylene propylene diene rubber, wherein, the magnesium carbonate is powdery, and the particle size is 40-80 mesh. Through the comprehensive selection of composition and process, the prepared shoe sole can transmit light, and at the same time, physical parameters such as elasticity, yellowing resistance, compression deformation and the like can meet the requirements of the shoe sole.

Description

technical field [0001] The invention relates to a light-transmitting foamed shoe sole composition, and also relates to a method for making shoe soles by using the composition. Background technique [0002] The luminous soles have two main functions, one is to increase the aesthetics and interest of the soles and attract consumers' desire to buy, and the other is to use the luminescence of the soles to serve as a warning or reminder. For example, in the Chinese invention patent entitled "luminous children's shoes" with the authorized notification number CN 202653265 U, a kind of luminous children's shoes is disclosed, which includes a shoe upper and a sole. A luminous layer is arranged inside the luminous surface. The luminous layer is a PU resin luminous powder or a PU resin fluorescent ink layer. Although this kind of shoes can play a luminous effect, there are still the following disadvantages: in the process of repeated deformation of the shoes under stress, the risk of...

Problems solved by technology

Although this kind of shoes can play a luminous effect, there are still the following disadvantages: in the process of repeated deformation of the shoes under stress, the risk of PU resin luminous powder or PU resin fluorescent ink layer falling off is relatively large, and the PU resin luminous powder Or the PU resin fluorescent ink layer is susceptible to scratching and wear and becomes invalid; whether the PU resin luminous powder or PU resin fluorescent ink layer can emit light and the length of the luminous time depends on the environment, and its practicability is relatively poor; PU resin luminous powder or PU resin The luminescent mode of the fluorescent ink layer is monotonous, which is not very attractive to consumers

[0003] For this reason, the industry has begun to study the soles that can transmit light. Although some soles can transmit light, the physical parameters such as elasticity, yellowing resistance, and compression deformation of the soles are greatly affected, and the overall performance of the entire sole is still difficult. satisfy
