Abstract
The invention discloses a rubber additive for improving the aging resistance of rubber, and a preparation method and application thereof. The invention comprises the following raw materials: 10-30 parts of alkyl phosphate, 5-10 parts of fatty acid amide, 10-30 parts of fatty glyceride, 10-25 parts of tridecyl alcohol trimellitate, 5-15 parts of sorbitan monolaurate, 10-35 parts of precipitated white carbon black and 1-5 parts of 3, 5-di-tert-butyl-4-hydroxybenzyl dioctadecyl phosphate; the invention also provides a preparation method of the rubber additive, and the rubber additive is used for preparing rubber products and improving the aging resistance of the rubber products. When the rubber additive is used for rubber products, peroxide radicals generated in the aging process of the rubber products can be absorbed, so that the consumption of an anti-aging agent for decomposing the peroxide radicals in the rubber products is reduced; the rubber additive can be regenerated after reacting with peroxide free radicals, so that the ageing resistance of rubber products is improved.
Description
Technical Field
The invention belongs to the technical field of processing aids, and particularly relates to a rubber additive for improving the aging resistance of rubber, and a preparation method and application thereof.
Background
Rubber products (rubber products) refer to various rubber products produced from natural rubber and synthetic rubber, and also include rubber products produced by recycling waste rubber. Rubber products are produced by first mixing rubber compounds with uniform and stable quality, wherein the rubber compounds are produced by mixing various compounding ingredients with rubber through a rubber mixing mill. The rubber additive, also called as a rubber processing aid, can help various compounding agents to be uniformly dispersed in rubber in a time-saving and labor-saving manner, and can also prevent nano-scale materials such as carbon black, white carbon black and the like from reuniting to form a rubber compound with uniform and stable quality.
Rubber and its products are gradually aged by heat, oxygen, ozone, valence-variable metal ions, mechanical stress, light, high-energy rays, etc. during long-term storage and use, and become sticky, hard, brittle, or cracked, resulting in decrease in physical and mechanical properties, loss of elasticity, and further loss of use value. Currently, rubber processing aids and compounding agents in existing rubber articles function independently of each other, for example: the processing aid and the anti-aging agent respectively and independently play roles, and the rubber product is lost after the anti-aging agent is exhausted; therefore, the obtained rubber product has poor aging resistance and cannot meet the requirement of automobiles and some high-end equipment on the replacement of rubber product parts for the whole life.
Disclosure of Invention
The invention aims to provide a rubber additive for improving the aging resistance of rubber, a preparation method and application thereof, and aims to solve the problem that in the prior art, a rubber processing aid and an anti-aging agent respectively and independently play a role, and the rubber processing aid and the anti-aging agent lose a protection effect on a rubber product after the anti-aging agent is exhausted, so that the obtained rubber product has poor aging resistance.
