Embodiment 1

[0011] A formula for retreading rubber tire treads, made of the following components in parts by weight: 20 parts of natural rubber, 80 parts of synthetic rubber, 3.5 parts of anti-aging agent, 0.3 part of vulcanizing agent, 10 parts of active agent, and 60 parts of reinforcing agent Parts, 2.8 parts of vulcanization accelerator, 4 parts of softener.

[0012] The anti-aging agent is selected from phenolic anti-aging agent with excellent heat resistance.

[0013] During preparation, the natural rubber is first masticated, then all the components are mixed and kneaded, vulcanized after kneading and molded, and then packaged after sorting and polishing.

Embodiment 2

[0015] A formula for retreading rubber tire treads, made of the following components in parts by weight: 10 parts of natural rubber, 70 parts of synthetic rubber, 2 parts of anti-aging agent, 0.1 part of vulcanizing agent, 6 parts of active agent, and 50 parts of reinforcing agent 1 part, 1 part vulcanization accelerator, 2 parts softener.

[0016] The anti-aging agent is selected from phenolic anti-aging agent with excellent heat resistance.

[0017] During preparation, the natural rubber is first masticated, then all the components are mixed and kneaded, vulcanized after kneading and molded, and then packaged after sorting and polishing.

Embodiment 3

[0019] A formula for retreading rubber tire treads, made of the following components by weight: 30 parts of natural rubber, 90 parts of synthetic rubber, 5 parts of anti-aging agent, 0.5 part of vulcanizing agent, 13 parts of active agent, and 70 parts of reinforcing agent parts, 4 parts of vulcanization accelerator, 8 parts of softener.

[0020] The anti-aging agent is selected from phenolic anti-aging agent with excellent heat resistance.

[0021] During preparation, the natural rubber is first masticated, then all the components are mixed and kneaded, vulcanized after kneading and molded, and then packaged after sorting and polishing.

Abstract

The invention discloses a formula for a recap tread. The formula is composed of the following components in parts by weight: 10-30 parts of natural rubber, 70-90 parts of synthetic rubber, 2-5 parts of an anti-aging agent, 0.1-0.5 part of a vulcanizing agent, 6-13 parts of an active agent, 50-70 parts of a reinforcing agent, 1-4 parts of a vulcanization accelerator and 2-8 parts of a softening agent. Compared with the prior art, the formula provided by the invention has the advantages that waste is reduced; production and manufacturing cost is saved; and the recap tread has the characteristicsof better resistance to abrasion, heat and oil and higher strength compared with a new tire, and better meets the working condition of a pneumatic-tired roller.

Description

technical field [0001] The invention relates to the technical field of retreaded rubber tires, in particular to a formula for retreaded rubber tire treads. Background technique [0002] Since the reform and opening up, my country's economy has developed rapidly, and the construction of infrastructure such as road traffic has become more and more important. A large number of rubber-tyred road rollers are required, which increases the consumption of rubber tires, and the units that own rubber-tyred road rollers are usually expensive to replace. The brand new rubber tires are used, and the replaced old tires are discarded, which increases the amount of industrial waste. Therefore, the refurbished rubber tire came into being. [0003] The tread of a new rubber tire is spliced ​​by two treads. Judging from the use of each vehicle, this kind of tread is prone to cracking in the middle and greatly affects the progress of the project. Retreaded rubber tires are a kind of retreaded ...
