Problems solved by technology

[0002] The sponge midsole is an essential part of rubber shoes. On the one hand, some inorganic fillers, such as clay and calcium carbonate, are used in the previous sponge midsole rubber formula, which has a large proportion and increases the weight during wearing. Human burden, walking the same distance, tends to consume more energy of the human body, making people prone to fatigue
On the other hand, under normal circumstances, during the wearing process of rubber shoes, due to the heat generated by sports friction, the soles of the feet are prone to sweating, and the sponge midsole absorbs sweat poorly, resulting in damp inside the rubber shoes, which will produce odor after a long time, and bacteria in dark and humid places It is easy to reproduce in the environment, causing beriberi, affecting people's normal work and life, reducing the quality of life, and causing great harm to people's health
The commonly used rubber foam sponge midsole anti-odor and anti-bacterial treatment is to add special chemical substances to the rubber material, which will be released gradually during the wearing process. The chemical substances can decompose and play the role of deodorant and anti-bacterial , but it will also produce harmful products that are harmful to human health, and because of its small dosage, it is easy to consume, and if it takes a little longer, it will lose its efficacy, and it will not have the effect of deodorization and antibacterial

Embodiment 1

[0018] 1) First, put 50kg of standard rubber into the rubber open mill for mastication, and pass it thinly until the plasticity reaches 0.6, then park, cool, check, and set aside;

[0019] 2) Put the masticated standard rubber into the rubber mixer for 1 minute, open the upper bolt of the mixer, add 0.6kg accelerator M, 0.9kg accelerator DM, 2.5kg zinc oxide, 10kg stearin acid and 0.75kg anti-aging agent RD, close the internal mixer; after 2 minutes of pressing, open the top bolt of the internal mixer, add 35kg of hemp and 15kg of softened oil, and fully compress until the load is stable and the pointer of the ammeter of the internal mixer does not stop. When swinging sharply, add 1.25kg of sulfur and 4kg of foaming agent H; after 30 seconds of pressing, open the lower top bolt of the internal mixer to discharge the material, and knead evenly on the flat machine, then press, cool, check, and set aside;

[0020] 3) Extrude and calender the above-mentioned mixed sponge rubber ma...

Embodiment 2

[0023] 1) First, put 100kg of standard rubber into the rubber open mill for mastication, and pass it thinly until the plasticity reaches 0.6, then park, cool, check, and set aside;

[0024] 2) Put the masticated standard rubber into the rubber mixer and press for 1 minute, open the upper bolt of the mixer, and add 1.2kg accelerator M, 1.8kg accelerator DM, 5kg zinc oxide, and 20kg stearic acid in sequence and 1.5kg anti-aging agent RD, turn off the internal mixer; after 2 minutes of pressing, open the top bolt of the internal mixer, add 70kg of hemp and 30kg of softened oil, and fully compress until the load is stable and the pointer of the ammeter of the internal mixer does not change significantly. When oscillating, add 2.5kg of sulfur and 8kg of foaming agent H; after 30 seconds of pressing, open the lower top bolt of the internal mixer to discharge the material, and knead evenly on the flat machine, then press, cool, check, and set aside;

[0025] 3) Extrude and calender t...

Embodiment 3

[0028] 1) First, put 200kg of standard rubber into the rubber mill for mastication, thin it out until the plasticity reaches 0.65, then park it, cool it, check it, and set it aside;

[0029] 2) Put the masticated standard rubber into the rubber mixer and press for 2 minutes, open the upper bolt of the mixer, and add 2.4kg accelerator M, 3.6kg accelerator DM, 10kg zinc oxide, 40kg stearic acid in sequence and 3kg anti-aging agent RD, turn off the internal mixer; after 2 minutes of pressing, open the top bolt of the internal mixer, add 140kg hemp and 60kg softened oil, and fully compress until the load is stable and the ammeter pointer of the internal mixer does not swing significantly At the same time, add 5kg sulfur and 16kg foaming agent H; after pressing for 30 seconds, open the lower top bolt of the internal mixer to discharge, and evenly press on the flat machine, then press, cool, check, and set aside;

Abstract

The invention relates to a new sponge insole and preparation method thereof. Preparation method of the invention comprises steps of: 1) first placing standard rubber to a rubber open mill to plasticate and to thin until plasticity reaches 0.6 to 0.65, stopping, cooling, checking for spare use; 2) casting the plasticated standard rubber to a rubber mixer to plasticize for 1 min to 2 min, adding accelerator M, accelerator DM, zinc oxide, stearic acid and antiager RD, stopping the mixer; after plasticizing for 2min, adding hemp and softening oil to plasticize adequately, then adding brimstone and foaming agent H; discharging after plasticizing for 30s and tabletting, cooling and checking for spare use after turning evenly on a flat-bed machine; 3) squeezing, calendaring plasticized sponge gelatine and die cutting the same to rubber pieces, then adhering insole on the rubber pieces, packing the same to a flat vulcanizing machine to vulcanize; 4) finally combining the vulcanized sponge insole with other parts of the rubber shoes via a rubber shoe forming device to vulcanize by hot air in a digestor.
