Abstract
The invention discloses a production process of fine rubber. The production process is characterized by comprising the following steps of: a, firstly, selecting used tyres and classifying the used tyres; cleaning the tyres and then crushing the tyres to 50-80 meshes; b, desulfurizing the rubber powder obtained in the step a in a devulcanizer, and adding a rubber activator, a rubber softener, a rubber plasticizer, a rubber expanding agent and water to the devulcanizer; and c, kneading the desulfurized rubber powder obtained in the step b in a kneading machine, and then filtering and refining the kneaded rubber powder, and finally, performing compression moulding of the rubber powder to finally obtain the finished product rubber. The production process of fine rubber provided by the invention is simple in process steps, easy to coordinate, and high in working efficiency; and the produced rubber is good in ductility, not easy to break and long in service life.
Description
Technical field
The present invention relates to the rubber technology field, relate in particular to a kind of production technology of meticulous rubber.
Background technology
The research and development of China's rubber industry specialty are not only improving aspect sizing material, technology, performance and the cost existing rubber in continuous progress, make it constantly to satisfy customer requirements and adapt to market demand, and continually develop new product and new technology.So waste and old regeneration of rubbers is produced and utilize particularly important of also seeming.The production craft step of rubber of the prior art is loaded down with trivial details, cooperates unreasonablely, causes inefficiency, and the rubber ductility of producing is not high, easily fracture.
Therefore, be badly in need of a kind of improved technology and solve existing this problem in the prior art.
Summary of the invention
The production technology that the purpose of this invention is to provide a kind of meticulous rubber.
The technical solution used in the present invention is:
A kind of production technology of meticulous rubber may further comprise the steps:
A: at first choose the junked tire classification, clean, pulverize again, be crushed to the 50-80 order;
B, the rubber powder of gained among the step a is carried out desulfurization in digester, add rubber activator, RX, rubber plastizing agent, rubber swelling agent and water in the digester;
C, the rubber powder after the desulfurization of gained among the step b is entered kneading in the masticator, refilter, refining, finished product rubber is made in last compression moulding.
Pulverize among the described step a and comprise that one-level is pulverized and secondary is pulverized, it is that the rubber after cleaned is crushed to the 10-20 order under the environment of normal temperature that described one-level is pulverized, described secondary pulverizing is that the rubber meal after one-level is pulverized is crushed to the 50-80 order in temperature under-80 ℃--120 ℃ the environment, is placed to normal temperature.
The interior temperature of digester is 200-250 ℃ among the described step b, and pressure is 1.8-2.3Mpa, and the time is 2-3h.
Digester carries out tail gas clean-up among the described step b.
Rubber activator described in the described step b is vulcanized sodium, oxalic acid, sodium carbonate or NaOH.
RX alkane or wood pitch described in the described step b.
Rubber plastizing agent described in the described step b is adjacent benzene, triethyl citrate or epoxy tetrahydro-2-ethylhexyl phthalate.
Rubber swelling agent described in the described step b is alunite or calcium oxide.
Advantage of the present invention is: processing step is simple, cooperate easily, and high efficiency, the rubber ductility of producing is good, is not easy fracture, long service life.
