Abstract
The invention belongs to the technical field of rubber and particularly relates to a waste rubber recycling and reusing method. The waste rubber recycling and reusing method comprises the following steps: washing a waste tire; crushing washed rubber in a crusher until the size is 20mm-30mm; sieving by a filter screen; grinding an undersized product by a grinding miller until the size is 5mm-10mm; sieving by the filter screen; continually grinding the undersized product in a grinding machine until the size is 0.5mm-1.4mm; sieving by the filter screen; and checking and packaging the undersized product to obtain rough rubber powder. By virtue of the waste rubber recycling and reusing method, the waste tires can be recycled and reused, and the prepared rough rubber powder can be combined with polyurethane to be used for sports grounds and sound-insulation and heat-preservation materials and can be combined with asphalt to be used for a road pavement material. According to the waste rubber recycling and reusing method, the process steps are simple and the waste tires are effectively utilized.
Description
Technical field
The invention belongs to field of rubber technology, particularly relate to a kind of recycling method of waste old.
Background technology
China is that rubber production uses big country, and the use amount of rubber is all increasing by a wide margin every year, thus creates a large amount of waste olds, and as can not these waste olds of efficiency utilization, these rubber will bring very large environment hidden danger.Therefore, recycling is carried out to waste old and become a problem demanding prompt solution.
Summary of the invention
The present invention is directed to the deficiency that prior art exists, the recycling method of the simple waste old of a kind of technique is provided.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of recycling method of waste old, comprises the following steps:
(1) being cleaned up by junked tire, the rubber after cleaning is crushed to 20 ~ 30mm in pulverizer, then through screen screening, sieve is ferrous contaminants;
(2) undersize of step (1) being ground to 5 ~ 10mm through grinder, then through screen screening, sieve is fiber;
(3) undersize of step (2) is continued to be ground to 0.5 ~ 1.4mm through abrasive machine, then after screen screening, by undersize test package, obtain thick rubber powder.
Wherein, the aperture of the sieves described in step (1) is 30mm;
The aperture of the sieves described in step (2) is 10mm;
The aperture of the sieves described in step (3) is 1.4mm.
The invention has the beneficial effects as follows: junked tire is recycled by the present invention, obtained thick rubber powder can be combined with polyurethane and be used for sports ground and sound and thermal insulating material, is combined is used for paveio(u)r with pitch; Processing step of the present invention is simple, and waste old is utilized effectively.
