Rubber shoe insole formula and production process thereof

Abstract

The invention discloses a rubber shoe insole formula. The rubber shoe insole formula is prepared from the following raw materials: pure natural rubber 1,000 g, a Japanese crystallite physical foaming agent 60 g, an antioxidant 15 g, zinc oxide 160 g, talcum powder 200 g, titanium dioxide 200 g, a DM9801 plasticizer 30 g, stearic acid 20 g, a CFP foaming agent 1.5 g, sulphur 20 g and a yellowing resistance agent 10 g. A production process comprises the following steps: (1) carrying out rubber mixing; (2) preparing an upper and an outsole; (3) feeding a rubber material in a mold; (4) matching a male mold with a female mold; (5) heating the male mold and the female mold; (6) finishing foaming; (7) cooling; (8) opening the mold; (9) decorating a shoe; and (10) packing. Compared with the prior art, the rubber shoe insole formula has the advantages that the rubber shoe insole formula is pollution-free, owing to the suitable hardness, a user feels comfortable, the labor intensity is reduced, the labor production efficiency is improved, and the labor cost is low. The shoe insole product is low-temperature-resistant, high in rebound resilience, anti-fatigue and mute, does not contain glue, and therefore is environmentally friendly.

Description

technical field [0001] The invention relates to shoe soles, in particular to a rubber shoe midsole formula and a production process thereof. Background technique [0002] Rubber has been used to make the outsole of shoes for nearly a hundred years, and rubber is also used to form the upper and bottom of shoes. Secondary vulcanization is carried out in the middle, so that the side bottom has a stronger combination. And rubber is also used to make the midsole of shoes, that is, the rubber material and foaming agent and other related additives are compounded with a certain formula to make rubber strips, wrapped in the insole cloth, and placed in the shoe cavity above the outsole. , together with the shoes in the vulcanization tank, the secondary vulcanization reaction is made into a rubber sponge, and the sponge does not have the function of bonding the rubber outsole and the upper. The foam shoe midsole made of this formula combines the molded shoe outsole and shoe upper cov...
