Abstract
The invention relates to a rubber production method mainly comprising the following steps: a, waste vulcanized rubber is cleaned, and impurities are removed; b, the cleaned waste vulcanized rubber is kneaded for 10min in an open mill, and is crushed; c, a regeneration agent, a softener or raw rubber is added into the crushed waste vulcanized rubber, and the waste vulcanized rubber is regenerated to a rubber finished product; the rubber finished product is kneaded for 5min in the open mill, wherein a temperature is controlled at 40-60 DEG C; and a rubber sheet is discharged. With the method, production cost is reduced, production efficiency is improved, and production quality is improved.
Description
Technical field
The present invention relates to a kind of rubber preparation method.
Background technology
Conventional regeneration glue industry has the history of more than 130 year.In recent years, China's reclaimed rubber is produced also larger development, has nowadays exceeded the scale of annual output 2500000 tons.In many known weeks, the production method of reclaimed rubber is normally classified according to sulfur method.Have with temperature classifications during desulfurization abroad, more than 100 DEG C is pyroprocess, and less than 100 DEG C is low temperature process.Current domestic industry renovation process mainly contains oil process, water/oil method, desulfurization rapidly method, screw rod desulfuration method and dynamic desulfurization etc.Oil process and water/oil method are all in digester, be heated to more than 170 DEG C by electrically heated or oil after waste rubber grain and catalyst mix, and keep about 6h.Owing to being the employing long-time oxicracking of high temperature and utilizing a large amount of oils swelling vulcanized rubber.Therefore reclaimed rubber obvious degradation, its physicals is poor and limit use range.The tensile strength of reclaimed rubber is generally no more than 10MPa, and homogeneous raw material micelle tensile strength is at about 20MPa.Therefore it can only do cheap packing material use, and due to oil process with water/oil method energy consumption is high, seriously polluted, production efficiency is low, progressively eliminated now, dynamic desulfurization is the new technology grown up in recent years, which overcome some problems that oil process occurs aborning, alleviate part to pollute, quality product and production efficiency have also been obtained corresponding raising.But still inevitably also exist energy consumption high, pollute and the shortcoming such as product performance are not enough.Owing to belonging to traditional industries, start easily, dog-eat-dog.Because production cost is high, profit is very micro-, adds the pollution wanting the recovery of three wastess(waste gas,waste water and industrial residue), and reclaimed rubber enterprise is made the matter worse.
Summary of the invention
technical problem
In view of this, the invention provides a kind of rubber preparation method.
solution
In order to solve the problems of the technologies described above, the invention provides a kind of rubber preparation method, the method mainly comprises the following steps: a. cleans useless cross-linked rubber, decon; B. by the useless cross-linked rubber after cleaning, put into machine pressure white silk pressure refining of beginning to pratise and pulverize after 10 minutes; C. after adding regenerator, tenderizer or rubber to the useless cross-linked rubber after pulverizing, regeneration reducing becomes rubber product, and mixing 5 minutes slices in the machine of beginning to pratise, temperature controls within 40-60 DEG C.
Preferably, in step a, micelle is 10-40 order, and waste rubber rim charge is 50-100 part.
beneficial effect
Compared with prior art; reduce production cost, improve production efficiency, quality product; present invention accomplishes the requirement of 21 century to environment protection simultaneously; make it along economic model that is capable of circulation, Sustainable development; achieve without waste water, produce without waste gas, free of contamination environment-friendly type, thus really realize the recycling economy of rubber.
Embodiment
The invention provides a kind of rubber preparation method, the method mainly comprises the following steps: a. cleans useless cross-linked rubber, decon; B. by the useless cross-linked rubber after cleaning, put into machine pressure white silk pressure refining of beginning to pratise and pulverize after 10 minutes; C. after adding regenerator, tenderizer or rubber to the useless cross-linked rubber after pulverizing, regeneration reducing becomes rubber product, and mixing 5 minutes slices in the machine of beginning to pratise, temperature controls within 40-60 DEG C.
Preferably, in step a, micelle is 10-40 order, and waste rubber rim charge is 50-100 part.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should described be as the criterion with the protection domain of claim.
