Problems solved by technology

According to its main function, it can be divided into anti-thermal oxygen aging agent, anti-ozonant, harmful metal ion inhibitor, anti-fatigue agent, ultraviolet absorber, anti-cracking agent, etc. As a major automobile production country, rubber tires are important parts of automobiles. The wear resistance, fatigue resistance, heat resistance and UV resistance of tire rubber are all factors to be considered in the anti-aging of this kind of rubber. Ordinary single anti-aging agent cannot achieve its comprehensive anti-aging effect, and many different anti-aging agents are required. synergistic effect

Embodiment 1

[0018] Example 1: A tire anti-aging agent, in parts by weight including the following components: anti-aging agent 402040-50 parts by weight, anti-aging agent RD40-50 parts by weight, anti-aging agent OD10-15 parts by weight, of which anti-aging agent 4020, anti-aging The weight ratio between RD and anti-aging agent OD is 4-5:4-5:1-1.5, and the weight ratio of different components in the anti-aging agent has various ratios, as shown in the following table , The ratio of practical effect is better: 40:45:15.

[0019]

[0020] The anti-aging agent 4020 of the present invention is N-(1,3-dimethylbutyl)-N-phenyl-p-phenylenediamine, and the anti-aging agent RD is 2,2,4-trimethyl -1,2-Dichlorinated quinoline polymer, the anti-aging agent OD is octylated diphenylamine. After the synergy between the anti-aging agents, the mixed product improves the overall wear resistance of the anti-aging agent. Resistance, fatigue resistance and UV resistance.

Embodiment 2

[0021] Example 2: The elastic carrier of the present invention is one or a mixture of natural rubber, styrene butadiene rubber, nitrile rubber, and chloroprene rubber. The preferred elastic carrier is 10-15 parts by weight, and the ductile carrier is used to assist in Kinds of antioxidants are mixed and adhered to form.

[0022] The dispersant of the present invention is one of stearic acid, liquid paraffin, and microcrystalline wax. The preferred dispersant is 2-3 parts by weight. The dispersant improves the dispersion effect of the elastic carrier and the anti-aging agent mixture, and mixes evenly .

[0023] The rubber oil of the present invention is used to improve the elasticity and ease of mixing of the elastic carrier, and is convenient to be mixed and molded with a low melting point antioxidant. The rubber reinforcing agent is used to increase the strength of the elastic carrier and increase the strength of the particles after molding. , The preferred rubber oil is 1-2 par...

Embodiment 3

[0025] Example 3: The preparation steps of the present invention are:

[0026] 1) Dissolve anti-aging agent 4020, anti-aging agent RD and anti-aging agent OD in acetone solution in sequence and mix thoroughly; filter to remove infusible impurities; low-melting anti-aging agent is not easy to use melt mixing, use the same solvent to mix, not mixing The effect is good, and it can also remove impurities in the antioxidant.

[0027] 2) Heat the elastic carrier to a molten state, and add dropwise the acetone solution in which the mixed ageing agent is dissolved while stirring; at the same time, add the dispersant and rubber oil sequentially.

[0028] 3) Stir for 2-3 hours, after the rubber reinforcing agent is fully stirred evenly, add the rubber reinforcing agent and cool to room temperature.

[0029] 4) The cooled mixture is stirred by a jet mill to obtain mixed fixed anti-aging agent particles.

Abstract

The invention discloses a tire anti-aging agent and a preparation method thereof, which comprises the following components in parts by weight: anti-aging agent 4020? 40-50 parts by weight, anti-aging agent RD? 40-50 parts by weight, anti-aging agent OD? 10-15 parts by weight, elastic carrier 10-15 parts by weight, dispersant 2-3 parts by weight, rubber oil 1-2 parts by weight, rubber reinforcing agent 0.5-1 parts by weight, including anti-aging agent 4020, anti-aging agent RD The ratio by weight and number between the antiaging agent OD is 4-5:4-5:1-1.5; The synergistic effect between the aging agents, the mixed anti-aging agent has good comprehensive effects in terms of wear resistance, fatigue resistance, and UV resistance, and at the same time, it is not easy to bloom when fused with rubber. The mixed anti-aging agent is elastic The carrier is fixed and formed, which is convenient for quantitative taking and storage, and has high practical effect.

Description

technical field [0001] The invention relates to the field of anti-aging agent manufacture, in particular to a mixed anti-aging agent applied to rubber tires. Background technique [0002] The aging of rubber can gradually reduce the performance of its products and completely lose the use value; in order to prolong the service life of rubber products, it is necessary to add some substances that can inhibit the aging process in rubber, thereby prolonging the storage period of rubber and its products and service life. [0003] There are many types of anti-aging agents and their functions are different. According to its main function, it can be divided into anti-thermal oxygen aging agent, anti-ozonant, harmful metal ion inhibitor, anti-fatigue agent, ultraviolet absorber, anti-cracking agent, etc. As a major automobile production country, rubber tires are important parts of automobiles. The wear resistance, fatigue resistance, heat resistance and UV resistance of tire rubber ...
