Embodiment 1

[0051] An EVA insole, calculated in parts by weight, and its raw material components are shown in Table 1.

[0052] Such as figure 1 As shown, the preparation method of the EVA insole includes the following steps:

[0053] S1: Take fresh orange peels and wash them, dry them in the sun and dry them in a blast drying oven, crush them with a grinder and pass through a 45-mesh sieve to obtain orange peel powder, mix the grapefruit peel powder and silver nitrate with water and mix well , Put it into a blast drying box and dry to obtain modified orange peel powder;

[0054] S2, preheat the double-roll mill to 90-100°C, and add EVA pellets;

[0055] S3, when the EVA is melted, add zinc oxide and zinc stearate and mix for 4-5 minutes;

[0056] S4, add AC blowing agent and DCP and mix for 5-6min;

[0057] S5, add modified orange peel powder, KH-560, chitosan, mix for 8-10 minutes, and then produce slices;

[0058] S6, cut the sheet, put it into a preheated mold, and place it on a flat vulcanizer,...

Abstract

The invention discloses an EVA sockliner and a preparation process thereof. The sockliner comprises the following raw materials: 75-80 parts of EVA; 2-4 parts of a foaming agent; 1-2 parts of a cross-linking agent; 0.5-1 part of a release agent; 3-4 parts of an activator; 5-10 parts of orange peel powder; 0.8-1 part of silver nitrate; and 0.3-0.5 part of a coupling agent. Orange peel has natural exchange capability and absorption characteristic, and is often used for removing peculiar smell in daily life. The orange peel contains hesperidin and has a certain antibacterial effect. The silver nitrate has a good antibacterial effect; the solution of silver nitrate is acidic and has certain corrosivity and oxidability and can react with reducing substances in orange peel; hemicellulose in theorange peel powder is easily degraded under the acidic condition, and lignin is subjected to a condensation reaction under the acidic condition, such that the micro-pore channels of the orange peel powder are fine and uniform, and the adsorption capacity of the modified orange peel powder is improved. Silver ions are adsorbed to the surfaces of particles of the orange peel powder and in micro-pores, so that the silver ions can be endowed with a slow release effect and the sockliner can be endowed with a lasting and effective antibacterial effect.

Description

Technical field [0001] The invention relates to the technical field of insoles, and more specifically, it relates to an EVA insole and its preparation process. Background technique [0002] The insole can not only improve the softness and comfort of the shoes, but also has the advantage of being easy to disassemble and clean to keep the shoes hygienic. [0003] The Chinese patent with publication number CN103859697B discloses an antibacterial insole and a preparation method thereof. The antibacterial insole is made of the following raw materials in parts by weight: 20-30 parts of ramie fiber, 40-60 parts of cotton fiber, and 20-30 parts of bamboo fiber. Parts, 0.5-1.5 parts of composite antibacterial agent; composite antibacterial agent is composed of the following components by weight percentage: polyhexamethylene biguanide hydrochloride 85-95% and coupling agent 5-15%; the coupling agent is composed of The following components are composed by weight percentage: 40-60% 2-[(2-amin...
