Embodiment 1

[0016] A kind of softening agent for the production of regenerated rubber, select waste oil as raw material, it comprises the following components by weight percentage: 30% of animal and vegetable oleic acid, 17% of arachidonic acid, 8% of stearic acid, 18% of glycerin; the balance is water and Impurities. Treatment method: first filter the waste oil to remove solid impurities such as mechanical suspended matter contained in it, and then let it stand for 11 hours, the water in the waste oil will deposit to the lower part, and release the water from the lower part, and then heat the waste oil to 200 ° C to make Distill the water remaining in the oil until the water content in the waste oil is less than 0.5%. After cooling down to room temperature, pump the oil into a closed container and heat it to 50-60°C, then vacuumize to remove the odor, and finally add the oil The weight of 5% carbon black is stirred evenly to obtain the softener for the production of regenerated rubber. ...

Embodiment 2

[0022] A kind of softening agent for the production of regenerated rubber, which uses gutter oil as raw material, and comprises the following components in weight percentage: 25% animal and vegetable oleic acid, 15% arachidic acid, 12% stearic acid, and 25% glycerin; the balance is water and Impurities.

[0023] First filter the waste oil to remove solid impurities such as mechanical suspensions contained in it, and then let it stand for 12 hours. The water in the waste oil will deposit to the lower part, and the water will be released from the lower part. Distill the water in the waste oil until the water content in the waste oil is less than 0.5%, remove the odor of the obtained oil by vacuuming, and finally add silicate with an oil weight of 5%, and stir evenly to obtain recycled rubber. softener.

Embodiment 3

[0025] The softening agent used for the production of reclaimed rubber is selected from waste oil raw materials and contains the following components in weight percentage: 20% animal and vegetable oleic acid, 25% arachidonic acid, 15% stearic acid, 15% glycerin; the balance is water and impurities. First filter the waste oil to remove solid impurities such as mechanical suspended matter contained in it, and then let it stand for 10 hours, the water in the waste oil will deposit to the lower part, and the water will be released from the lower part, and then the waste oil will be heated to 180 ° C to make the remaining Distill the water in the waste oil until the water content in the waste oil is less than 0.5%, remove the odor of the obtained oil by vacuuming, and finally add active calcium carbonate with an oil weight of 5%, and stir evenly to obtain regenerated rubber. softener.

Abstract

The invention discloses a softener for producing regenerated rubber and belongs to the technical field of softeners. The softener takes swill-cooked dirty oil as a raw material, wherein the swill-cooked dirty oil contains main components in percentage by weight as follows: 20-30 percent of animal and plant oleic acid, 15-25 percent of arachidonic acid, 8-15 percent of stearic acid and 15-25 percent of glycerol. The swill-cooked dirty oil is prepared into the softener for producing the regenerated rubber through work procedures of filtering, removing water, deodorizing and adding a reinforcing agent. The softener disclosed by the invention has the advantages of wide raw material sources, low cost and simple treatment process; and the softener can be used for producing environment-friendly regenerated rubber, provides a new path for recycling and innocent treatment and can effectively prevent the swill-cooked dirty oil from reflowing to dinning tables and harming the human health.

Description

technical field [0001] The invention belongs to the technical field of softening agents, and in particular relates to a softening agent for the production of recycled rubber using waste oil as a raw material. Background technique [0002] Softener is a very important auxiliary in the production of regenerated rubber. It facilitates the swelling and chain breaking of rubber powder during the regeneration of regenerated rubber, and helps other additives to disperse in the reclaimed rubber powder, improving the regeneration effect and speeding up the regeneration. Speed, at present, most of the softeners used in the production of recycled rubber are coal tar or aromatic oil. Both of the above two softeners have serious pollution, especially coal tar contains a large amount of carcinogens such as benzene and naphthalene, which not only endanger the health of workers, but also produce The content of polycyclic aromatic hydrocarbons in regenerated rubber does not meet the requirem...
