preparation example Construction

[0025] A preparation method of anti-aging rubber and plastic, comprising the following raw materials in proportion by weight: 40-80 parts of natural rubber, 30-70 parts of styrene-butadiene rubber, 5-10 parts of high styrene resin, dioctyl sebacate 10-15 parts, 6-12 parts of phenolic resin, 3-5 parts of vulcanization accelerator, 2-7 parts of active agent, 0.1-0.5 parts of antioxidant and 5-10 parts of light stabilizer.

[0026] The antioxidant is N-phenyl-α-naphthylamine and alkylphenothiazine, wherein the mass ratio of N-phenyl-α-naphthylamine to alkylphenothiazine is 2:1.

[0027] Light stabilizers are carbon black, zinc oxide, benzophenones, salicylic acids and metal complexes, wherein the mass of carbon black, zinc oxide, benzophenones, salicylic acids and metal complexes The ratio is 5:1:1:1:2.

[0028] The metal complex is an organic complex of nickel, cobalt and iron, wherein the mass ratio of nickel, cobalt and iron is 1:1:1.

[0029] The active agent is stearic aci...

Embodiment 1

[0031] A preparation method of anti-aging rubber and plastic, comprising the following steps:

[0032] 1) Take 40 parts of natural rubber and 30 parts of styrene-butadiene rubber, put them into an internal mixer, and masticate at a temperature of 50°C for 1 hour;

[0033] 2) Put the masticated rubber in the internal mixer, and take 5 parts of the light stabilizer and add it to the internal mixer, and mature together at a temperature of 35°C for 4 hours;

[0034] 3) Take 5 parts of high styrene resin, 10 parts of dioctyl sebacate, and 6 parts of phenolic resin, put them into the internal mixer, and banbury at 60°C for 20 minutes;

[0035] 4) After 20 minutes, take 3 parts of vulcanization accelerator, 2 parts of active agent and 0.1 part of antioxidant into the internal mixer, mix for 20 minutes at a temperature of 80°C, and release the sheet at a debinding temperature of 30°C , After kneading, leave the sheet for 24 hours to obtain an anti-aging rubber sheet.

Embodiment 2

[0037] 1) Take 50 parts of natural rubber and 40 parts of styrene-butadiene rubber, put them into an internal mixer, and masticate at a temperature of 60°C for 1.5 hours;

[0038] 2) Put the masticated rubber in the internal mixer, and take 6 parts of the light stabilizer and add it to the internal mixer, and mature together at a temperature of 40°C for 5 hours;

[0039] 3) Take 6 parts of high styrene resin, 11 parts of dioctyl sebacate, and 8 parts of phenolic resin, put them into the internal mixer, and banbury at 65°C for 20 minutes;

[0040] 4) After 20 minutes, take 3 parts of vulcanization accelerator, 3 parts of active agent, and 0.2 parts of antioxidant into the internal mixer, mix at 80°C for 25 minutes, and release the sheet at 40°C for debinding , After kneading, leave the sheet for 24 hours to obtain an anti-aging rubber sheet.

Abstract

The invention relates to the technical field of rubber and plastic preparation, and discloses a preparing method of anti-ageing rubber and plastic. The anti-ageing rubber and plastic is prepared from,by weight, 40-80 parts of natural rubber, 30-70 parts of butadiene styrene rubber, 5-10 parts of high styrene resin, 10-15 parts of dioctyl sebacate, 6-12 parts of phenolic resin, 3-5 parts of a vulcanization accelerator, 2-7 parts of an active agent, 0.1-0.5 part of an antioxidant and 5-10 parts of a light stabilizer. The antioxidant and the light stabilizer are added, the antioxidant can delayor restrain the oxidation process of the rubber and plastic material, prevent the ageing of the rubber and plastic material and prolong the service life of the rubber and plastic material, the light stabilizer can shield or absorb the energy of ultraviolet rays, quench singlet-state oxygen and decompose hydroperoxide into inert matter, and therefore high-molecular polymers under the irradiation oflight can eliminate or delay the photochemical reaction probability, prevent or delay the light ageing process and thus prolong the service life of the rubber and plastic product and effectively improve the anti-ageing performance of the rubber and plastic product.

Description

technical field [0001] The invention relates to the technical field of rubber and plastic preparation, in particular to a preparation method of anti-aging rubber and plastic. Background technique [0002] Rubber and plastic is the collective name of the rubber and plastic industries. They are all subsidiary products of petroleum. They are all the same in source. However, in the process of making products, their physical properties are different, and their uses are even more different. The most common is tires. Plastics are becoming more and more widely used with the needs and uses of technology and markets, and they are inseparable from daily life. [0003] With the increasing use of rubber and plastics, the market competition in the rubber and plastics industry is increasing. During the use of rubber and plastics, depending on the environmental conditions of the finished rubber and plastic products, as time goes by, it will cause rubber and plastic damage. Cracks or harden...
