Problems solved by technology

[0026] Chinese patent CN100486789C continuously treats the surface of waste rubber powder through a microwave device, so that it can process the surface of waste rubber powder continuously and more effectively. The reclaimed rubber has good surface roughness and processability, and the physical and chemical properties of the product Both have been improved; the disadvantage is that the desulfurization effect is poor and a large amount of waste gas is generated
The disadvantage is that the equipment is complicated, the desulfurization is insufficient, the effect is poor, and a large amount of waste gas is generated.
[0032] The regeneration temperature of the above-mentioned technologies and methods is greater than 100°C, which belongs to high-temperature regeneration, which inevitably produces a large amount of waste gas and seriously pollutes the production environment.

Embodiment 1

[0047] The airtight stirring reaction equipment is a 5L screw bottom discharge microwave kneader. There are 2 reserved holes on the kneader cylinder cover, which are respectively connected to the DN15 vacuum pipe and the DN15 vent port; a 1KW microwave generator is installed in the kneader cylinder with a waveguide connection. The center of the cover; the outside of the cylinder is a heat exchange jacket, and there is a heat medium in the jacket, and the heat medium is heated by electric heating.

[0048] Step 1: Add 1.3 kg of 24 mesh waste tire rubber powder and 88 g of 100# petroleum asphalt to the kneader.

[0049] Step 2: Turn on the electric heating.

[0050] Step 3: Turn on the kneader to stir.

[0051] Step 4: When the temperature of the material reaches above 60°C, turn on the microwave generator under the stirring state, and carry out microwave physical regeneration of the whole tire rubber powder for 10 minutes, and complete the regeneration production of this batch...

Embodiment 2

[0053] Add 1.3 kg of 24-mesh waste tire rubber powder and 98 g of 100# petroleum asphalt to the kneader; other steps are the same as in Example 1, the regeneration start temperature is 70°C, and microwave physical regeneration takes 9 minutes.

Embodiment 3

[0055] Add 1.3 kg of 24-mesh waste tire rubber powder and 103 g of 100# petroleum asphalt to the kneader; other steps are the same as in Example 1, the regeneration start temperature is 80°C, and microwave physical regeneration is performed for 10 minutes.

[0056] The following table is the analysis data of the regenerated rubber product produced by the odorless reclaimed rubber production method of the present invention:

Abstract

The invention discloses an odorless reclaimed rubber production method. Under low pressure and low temperature states, rubber powder and an accelerant are added into sealed stirring reaction equipmentto perform physical regeneration to produce reclaimed rubber. The odorless reclaimed rubber production method disclosed by the invention has the advantages of low temperature and low pressure regeneration conditions, no waste gas generation, greenness and environmental friendliness.

Description

technical field [0001] The invention relates to a production method of odorless reclaimed rubber, which belongs to the field of waste rubber resource recycling and utilization. Background technique [0002] China is a big country in the production of rubber products. A large amount of rubber has caused very serious environmental pollution after use, resulting in a serious waste of resources. In 2016 alone, my country's tire production has reached 940 million, and more than 130 million waste tires have been produced. [0003] Strengthening the effective recycling of waste rubber resources can achieve huge returns in terms of environmental protection, resources, and income. It is very important to promote reasonable and high-quality recycling of waste rubber. [0004] Rubber regeneration methods can be roughly divided into three categories: physical regeneration, chemical regeneration and microbial regeneration; according to the regeneration temperature conditions, it is divi...
