Description
Technical field
The present invention relates to a kind of rubber regeneration method.
Background technology
Because world's oil resources are in short supply, all kinds of rubber prices are caused to rise steadily, therefore rationally using regenerated resources, drop
Low production cost will be inevitable choice.The coming years, rubber sources is in short supply will always to perplex countries in the world, and China also formulates
Strategy on recycling economy development, therefore rubber sources recycling also seems more and more important.
With the development of modern society, the increase of rubber-consumer amount, the yield of scrap rubber is also more and more, but waste and old rubber
Glue has to pass through regeneration and can recycle, and regeneration causes that waste old is turned waste into wealth, and improves its use value.With the world
Environmental consciousness is improved constantly, the outlet that all reclaimed rubbers for making softening agent with coal tar of publicity are all refused in the world.And China regenerates
Glue producer is typically used with using common sizing material, product quality is lifted.Due to using coal tar in reclaimed rubber production process
Used as softening agent, there is strong foul odour production scene to oil, there is very big pollution to environment.
Therefore, active demand now is had become to sub- rubber environmental protection regeneration techniques.
The content of the invention
It is an object of the invention to provide a kind of rubber regeneration method.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：
A kind of rubber regeneration method, comprises the following steps：Waste old is selected first, is cleaned successively, dried, cut
, then be placed in the rubber after crushing in reactor and desulfurizing agent is added by block, pulverising step, stirs so that reaction is filled
Point, then rubber is placed in cooling tower is cooled down, the rubber after cooling is pressed through the conche in moulding equipment, mill
Piece is made, reclaimed rubber finished product is made.
The relevant content of above-mentioned technical proposal is explained as follows：
In above-mentioned technical proposal, clean, dry, stripping and slicing, pulverising step are carried out at normal temperatures, it is in small, broken bits after rubber fineness extremely
Below 40 mesh.
Preferably, at 250-600 DEG C, heating rate is 50-80 DEG C/h to the temperature control in reactor.
Preferably, it is additionally added softening agent in reactor.
Preferably, softening agent is aliphatic acid.
Because above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：
The linear strand of rubber is not destroyed, and feeding and operation are safe, and environmental protection is tasteless, saves petroleum resources, improves sizing material
Quality, non-environmental-pollution reduces the equipment requirement to producing, and reduces production cost.
