Problems solved by technology

In recent years, due to abnormal climate and frequent disasters, it is difficult to estimate the increase or decrease of natural rubber production, the shortage of raw materials, the soaring oil price, and the production of synthetic rubber is also in trouble. At present, rubber raw materials are still in short supply in my country, and a large number of them rely on imports. The situation has not fundamentally changed
A large amount of leftovers and discarded old tires produced in the tire production process have not been well utilized, not only causing serious "black pollution", but also wasting precious resources
In the prior art, the leftovers from the production of automobile rubber tires are used as the main raw material, and the waste rubber is modified to directly recycle the rubber fenders, but there are no literature and application reports yet.

Embodiment 1

[0011] Embodiment 1: The weight ratio of the components of the present invention is: in terms of 100 parts, the synthetic rubber NBA is 4 parts, the heat stabilizer is 0.6 part, the antioxidant is 0.4 part, the plasticizer DOP is 40 parts, and the internal lubricant 4 parts, 8 parts of filling reinforcing agent, 6 parts of polyester staple fiber, and automobile tire scraps as the balance.

[0012] The method for producing rubber fenders from automobile tire scraps includes the following steps: the first step is to classify and select the automobile tire scraps, crush them, clean them, dry them, and put them into a high-speed mixer for high-speed heat sealing with the plasticizer DOP liquid. Heat the raw material to fully absorb the plasticizer DOP liquid, and proceed at a temperature below 95°C until the raw material is completely dry; the second step is to put the high-speed mixture into the internal mixer, and add synthetic rubber NBA and other auxiliary materials for closed ...

Embodiment 2

[0013] Embodiment 2: The weight ratio of the components of the present invention is: in terms of 100 parts, the synthetic rubber NBA is 6 parts, the heat stabilizer is 0.4 part, the antioxidant is 0.6 part, the plasticizer DOP is 40 parts, and the internal lubricant 4 parts, 12 parts of filling reinforcing agent, 4 parts of polyester staple fiber, and leftovers of automobile tires as the balance. All the other refer to Example 1.

Embodiment 3

[0014] Embodiment 3: The weight ratio of the components of the present invention is: based on 100 parts, the synthetic rubber NBA is 5 parts, the heat stabilizer is 0.5 part, the antioxidant is 0.5 part, the plasticizer DOP is 35 parts, and the internal lubricant 5 parts, 10 parts of filling reinforcing agent, 5 parts of polyester staple fiber, 0.2 part of vulcanizing agent, 0.2 part of vulcanization accelerator, and the balance of automobile tire scraps. All the other refer to Example 1.

Abstract

The invention discloses a rubber fender produced by using automobile tyre leftovers and a method for producing same. The rubber fender is produced by using the auto tyre leftovers as a main material and adding auxiliary materials of synthetic rubber, a heat stabilizer, an antioxidant, a plasticizer DOP, an internal lubricant, a filling reinforcing agent, polyester short fiber and the like. The rubber fender is produced by using the leftovers of automobile rubber tyre production as the main raw material, waste rubber is modified and is recycled directly, renewable resources are recycled for comprehensive utilization, and a large number of waste rubber resources after production and consumption are recycled and changed into valuable, thus the three principles of 'minimization, reusing and recycling' is met, the resource comprehensive utilization rate is improved and energy resources are saved. The rubber fender has simple production process and low production cost, and is advantageous for market promotion.

Description

technical field [0001] The invention relates to a rubber fender, in particular to a rubber fender produced by using leftovers of automobile tires and a production method thereof. Background technique [0002] Rubber fenders have become one of the indispensable protective equipment in modern port engineering construction. In recent years, due to abnormal climate and frequent disasters, it is difficult to estimate the increase or decrease of natural rubber production, the shortage of raw materials, the soaring oil price, and the production of synthetic rubber is also in trouble. At present, rubber raw materials are still in short supply in my country, and a large number of them rely on imports. The situation has not fundamentally changed. A large amount of leftovers and discarded old tires produced in the tire production process have not been well utilized, not only causing serious "black pollution", but also wasting precious resources. In the prior art, the leftovers from th...
