Degradable foaming sole

Abstract

The invention provides a degradable foaming sole, which is prepared from the following raw materials in percentage by weight: 40 to 50 percent of EVA, 0.1 to 1 percent of crosslinking auxiliary agents, 0.1 to 3 percent of corn flour, 0.1 to 3 percent of lime cream, 0.1 to 3 percent of hexadienoic acid and 40 to 60 percent of low-melting point polyester slices. The degradable foam sole has the characteristics that the weight is light; wear-resistant performance and anti-slip effects are achieved; the dimension is stable.

Description

technical field [0001] The invention belongs to the technical field of material science, and in particular relates to a degradable foamed shoe sole. Background technique [0002] EVA foam materials have the characteristics of slipping, not being puncture-resistant and hardening at low temperature. Elastomer has good compatibility with EVA, and it is easy to form a dispersed phase in the system, which can reduce the force between molecular chains and play a plasticizing role. The addition of elastomer materials can improve the compression deformation of EVA foam materials. Wear-resistant, anti-slip, folding-resistant and other properties, to produce materials with low price and better performance, so as to meet people's special needs for material properties. At the same time, the density and tear strength of the EVA foam material remained basically unchanged, while the tensile strength and hardness showed a downward trend, the elongation at break increased, and the softness ...

Problems solved by technology

However, the mold temperature for one-time injection molding is 175°C-185°C, and the time is 250-270 seconds, the production efficiency is obviously low, the vulcanization time needs to be further shortened, and the bridging agent used is low-melting point polyester chip (DCP). Obvious odor, containing the sum of acetophenone and 2-phenyl-2-propanol exceeding 500mg / kg, which does not meet the environmental requirements of "Detox Action"; use bridging agent di-(tert-butylperoxyisopropyl ) Benzene (BIBP) foam soles contain acetophenone and 2-phenyl-2-propanol in excess of 40mg / kg, which is expected to meet the restrictions of major international brand manufacturers including Nike, Adidas, Skechers, etc. ( The sum of acetophenone and 2-phenyl-2-propanol is less than 50mg / kg), but there are residual free radicals that cause mold sticking
