preparation example Construction

[0017] An environment-friendly and high-performance rubber preparation method of the present invention specifically comprises the following steps:

[0018] Step 1, first pre-process the recycled tires;

[0019] The preprocessing process of step 1 is as follows:

[0020] Sort the recycled tires according to the same batch number and origin, and then clean and dry the sorted tires according to the sorted categories.

[0021] Step 2, grinding the tire treated in step 1 into rubber powder, adding the rubber powder into a desulfurization tank containing water, and stirring evenly;

[0022] In step 2, 8-10 unit weight of water is added, and 100 unit weight of rubber powder is added.

[0023] Step 3, add xanthate, stearic acid, rosin and activator in sequence to the desulfurization tank, stir evenly, and go through the desulfurization process to make gum.

[0024] In step 3, 0.1-1 weight unit of xanthate is added, 0.2-0.5 weight unit of stearic acid is added, and 0.8-1.5 weight un...

Embodiment 1

[0028] The recovered tires are classified according to the same batch number and origin, and then the classified tires are cleaned and wiped dry according to the classified categories; then the treated tires are ground into rubber powder, and the rubber powder is added with water. In the desulfurization tank, stir (add the rubber powder of 100 unit weights, the water of 8 unit weights here); Then in the desulfurization tank, add the xanthate of 0.1 weight units, the stearic acid of 0.2 weight units, 0.8 weight units successively The rosin and the activator per weight unit are stirred evenly and then go through the desulfurization process to make gum. In the desulfurization process, the temperature is 400° C. and the desulfurization time is 3 hours.

Embodiment 2

[0030] The recovered tires are classified according to the same batch number and origin, and then the classified tires are cleaned and wiped dry according to the classified categories; then the treated tires are ground into rubber powder, and the rubber powder is added with water. In the desulfurization tank, stir (add the rubber powder of 100 unit weights, the water of 9 unit weights here); Then in the desulfurization tank, add the xanthate of 0.5 weight units, the stearic acid of 0.3 weight units, 0.9 weight units successively The rosin and the activator per weight unit are stirred evenly and then go through the desulfurization process to make gum. In the desulfurization process, the temperature is 420° C. and the desulfurization time is 4 hours.

Abstract

The invention discloses a preparation method of an environment-friendly and high performance rubber. The method specifically includes the steps of: 1, firstly performing pretreatment on recovered tires; 2, grinding the tires treated by step 1 into rubber powder, also adding the rubber powder into a desulfurization tank containing water, and stirring the substances evenly; and 3, adding xanthogenate, stearic acid, rosin and an activating agent into the desulfurization tank, stirring the substances evenly, and then conducting desulfurization to make rubber. The method utilizes waste tires as theraw materials, recycles rubber waste, and solves the problem of lack of rubber resources at present.

Description

technical field [0001] The invention belongs to the technical field of rubber preparation, and relates to an environment-friendly and high-performance rubber preparation method. Background technique [0002] Rubber is an elastic polymer, and rubber can be divided into artificial rubber and natural rubber; my country is a country with very limited rubber resources. With the development of the automobile industry, the consumption of rubber has gradually increased. The amount of rubber waste is increasing year by year, which has a great impact on environmental protection. Therefore, in the case of such a shortage of rubber, it is necessary to recycle rubber waste and use waste tires to re-produce rubber, which saves resources and protects the environment. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an environment-friendly and high-performance rubber preparation method, which utilizes waste tires as raw materials to recycle rubber waste...
