Problems solved by technology
The pyrolysis process of waste tires generally requires high temperature and high pressure, which not only consumes a lot of energy, but also wastes rubber resources seriously. At the same time, the operation is dangerous, so it is not the best way to recycle waste tires

Embodiment 1
[0028] An environmentally friendly recycled rubber, which contains the following components by weight percentage: 0.5% sugar alcohol, 3% heavy oil, 3% dehydrated pine tar, 5% resin oil, 0.025% naphthenic rubber oil, and the rest is tire The mixed rubber powder of surface rubber powder and sidewall rubber powder, and the mixed rubber powder of tread rubber powder and sidewall rubber powder includes 80%-95% of tread rubber powder and 5%-20% of sidewall rubber powder by weight percentage Rubber powder, tread rubber powder, and sidewall rubber powder are all 20-40 mesh in particle size.
Embodiment 2
[0030] With embodiment 1, the difference is that all that adopt in the present embodiment is tread rubber powder.
Embodiment 3
[0032] Same as Example 1, the difference is that all the tires used in this example are sidewall rubber powder.

Abstract
The invention relates to the field of waste rubber recycling, and discloses environment-friendly reclaimed rubber and a preparation method thereof. The environment-friendly reclaimed rubber comprisesthe following components by weight: 0.5% of sugar alcohol, 3% of heavy oil, 3% of dehydrated pine tar, 5% of resin oil, 0.025% of naphthenic rubber oil, and balance of tread rubber powder or sidewallrubber powder or mixed powder of the tread rubber powder and the sidewall rubber powder, and is sealed and continuously produced by the process of processing by a strip-cutter, processing by a block-cutter, processing by a crusher, magnetic separation, screening, mixing, conveying, medium temperature mixing, desulphurization plasticization, extrusion molding, and the like. The method adopts a high-temperature and normal-pressure pipeline spiral regeneration method, and has the advantages of less formula auxiliary materials, no exhaust gas overflow, saving energy and environmental friendliness,and conforms to EU standards, a low-temperature and high-pressure screw extruder is used to form tablets or granules, investment of an open mill and a mixer unit can be reduced, investment in equipment and workshops can be saved, production efficiency is high, and the quality of the environment-friendly reclaimed rubber is stable. At the same time, waste steel wire tire rubber powder is used as amain raw material, the waste is used, resources are saved, environment is protected, and energy is saved.
Description
technical field [0001] The invention relates to the field of waste rubber regeneration, in particular to an environment-friendly regenerated rubber and a preparation method thereof. Background technique [0002] At present, my country is a big tire producer and tire consumer, but at the same time, my country is also the world's largest country in the number of waste tires. In 2016, the national production of waste tires was about 300 million, with a weight of more than 10 million tons. And the waste tires produced every year are increasing sharply at a rate of 8%-10%. By 2020, the number of waste tires in my country will reach 20 million tons. As the pollution of waste rubber becomes more and more serious, waste rubber has become another major pollution after white pollution - black pollution. How to effectively recycle and prevent environmental pollution is not only a worldwide problem, but also a new issue facing my country's recycling of renewable resources. With the c...
