Embodiment 1

[0029] (1) Preparation of reclaimed rubber: 1 part by mass of onion essential oil is mixed into 100 parts by mass of shoe sole rubber powder, and after mixing, it is directly placed on a double-roll mill for several times to obtain reclaimed rubber;

[0030] (2) Preparation of rubber compound: 100 parts by mass of styrene-butadiene rubber was masticated to cover rolls on a two-roll mill, and then 5 parts by mass of reclaimed rubber was added. After mixing evenly, add 5 parts by mass of zinc oxide, 1 part by mass of stearic acid, 1 part by mass of antioxidant RD, 45 parts by mass of carbon black N220, and finally add 1.7 parts by mass of accelerator CZ, 2 parts by mass of accelerator Agent D, 1.4 parts by mass of sulfur, mixed evenly, and thinly passed through the sheet, to obtain the rubber compound;

[0031] (3) Preparation of vulcanized rubber: after parking the mixed rubber for 16 hours, measure the positive vulcanization time t90 at 150°C with a UR2030 vulcanizer, and fina...

Embodiment 2

[0033] (1) Preparation of reclaimed rubber: 3 parts by mass of onion essential oil was mixed into 100 parts by mass of shoe sole rubber powder, and after mixing, it was directly placed on a double-roll mill for several times to obtain reclaimed rubber;

[0034] (2) Preparation of rubber compound: 100 parts by mass of styrene-butadiene rubber was masticated to cover rolls on a two-roll mill, and then 10 parts by mass of reclaimed rubber was added. After mixing evenly, add 5 parts by mass of zinc oxide, 1 part by mass of stearic acid, 1 part by mass of antioxidant RD, 45 parts by mass of carbon black N220 in sequence, and finally add 1.7 parts by mass of accelerator CZ, 2 parts by mass of accelerator Agent D, 1.4 parts by mass of sulfur, mixed uniformly, and thinly passed out to obtain a rubber compound;

[0035] (3) Preparation of vulcanized rubber: after parking the mixed rubber for 16 hours, measure the positive vulcanization time t90 at 150°C with a UR2030 vulcanizer, and fi...

Embodiment 3

[0037] (1) Preparation of reclaimed rubber: 5 parts by mass of onion essential oil was mixed into 100 parts by mass of rubber powder for sole rubber, and after mixing, it was directly placed on a double-roller mill for several times to obtain reclaimed rubber;

[0038](2) Preparation of rubber compound: 100 parts by mass of styrene-butadiene rubber was masticated to cover rolls on a two-roll mill, and then 15 parts by mass of reclaimed rubber was added. After mixing evenly, add 5 parts by mass of zinc oxide, 1 part by mass of stearic acid, 1 part by mass of antioxidant RD, 45 parts by mass of carbon black N220, and finally add 1.7 parts by mass of accelerator CZ, 2 parts by mass of accelerator Agent D, 1.4 parts by mass of sulfur, mixed evenly, and thinly passed through the sheet, to obtain the rubber compound;

Abstract

The invention belongs to the field of rubber application, and particularly discloses a method for preparing rubber by using onion essential oil as a rubber regenerant. The method comprises the following steps: proportionally doping onion essential oil into 100 parts by mass of shoe sole rubber powder, uniformly mixing, and directly placing several times on a double-roller open mill to obtain reclaimed rubber; plasticizing 100 parts by mass of a substance A on a double-roller open mill until banding, and adding a plurality of parts of the reclaimed rubber; uniformly compounding, proportionally and sequentially adding zinc oxide, stearic acid, an anti-aging agent RD and a substance B, finally sequentially adding an accelerator and sulfur, compounding uniformly, and carrying out thin passing discharge, thereby obtaining compounded rubber; and standing the compounded rubber for some time, determining the correct vulcanization time, and finally, vulcanizing on a vulcanizer to obtain the vulcanized rubber sample. The method has the advantages of wide raw material sources, environment friendliness and no toxicity. The prepared rubber has better properties, has wide application prospects, and can generate favorable economic benefit and environmental benefit.

Description

technical field [0001] The invention belongs to the field of rubber applications, and in particular relates to a method for preparing rubber by using onion essential oil as a rubber regeneration agent. Background technique [0002] The rubber industry, as an indispensable sector in the chemical industry, has also produced a large amount of waste rubber that is difficult to recycle while making an indelible contribution to economic development. Because rubber has an interconnected three-dimensional system, waste rubber cannot be remelted and dissolved for recycling like thermoplastics, which has become a major problem in the recycling of waste rubber. If these mountains of waste rubber are not properly disposed of, they will not only pollute the environment and breed mosquitoes, but also waste precious rubber resources. [0003] The early regeneration method is to crush the waste rubber into rubber powder, soak it with organic solvents (such as dibenzyl disulfide, xylene dis...
