Abstract
The invention discloses a kind of renovation process of junked tire, it is related to reclaimed rubber production technical field.The renovation process of junked tire of the present invention is：Waste old is cleaned, cuts glue, crushes, obtains rubber powder；Rubber powder, desulfurizing agent dibutyl disulfide and softening agent aliphatic acid are positioned in ultrasonic equipment, stirred, ultrasonic assistant desulfurization；After the completion of desulfurization, products therefrom is subjected to tabletting, obtains reclaimed rubber.The present invention carries out desulfurization using the method for ultrasonic assistant desulfurizing agent, and its operative temperature is low, avoids high temperature from easily making carbon-carbon bond fracture, make the shortcomings that hydraulic performance decline of reclaimed rubber, desulfurization time is short, and desulfurized effect is good, reclaimed rubber function admirable.
Description
Technical field
The present invention relates to reclaimed rubber production technical field, especially a kind of renovation process of junked tire.
Background technology
As the development of modern society, the increase of rubber-consumer amount, the yield of scrap rubber are also more and more, but waste and old rubber
Glue has to pass through regeneration and can recycled, and regeneration causes waste old to turn waste into wealth, and improves its use value.Rubber regeneration
Refer to using physics, chemical or biological method, destroy rubber cross network, formed linearisation, can reprocess
Process.Traditional technique for regenerated rubber flow is：Waste old-washing-coarse crushing-fine crushing-sieving-separation is fine
Dimension and metal sundries-desulfurization-cleaning-pressure water-drying-kneading-filter glue-freshening-refining-finished product, and it is therein de-
Sulphur process is then the most important thing of reclaimed rubber production process, and the effect of vulcanization is to influence the key factor of reclaimed rubber product quality.
At present, the method for regenerating waste or used rubber mainly includes chemical method and microbial desulfurization method.Chemical method is mainly wrapped
Oil process, water/oil method and dynamic desulfurization are included, its desulfurized effect is obvious, but under the high temperature conditions, and carbon-carbon bond is compared with easy fracture, often
Many small molecules fragments are produced, make the hydraulic performance decline of reclaimed rubber, in addition the volatilization of Pintsch process and scrap rubber small molecular, can be to big
Gas and water source cause greatly to pollute；Microorganism can make the superficial layer of scrap rubber powder become sticking pasty state from flexible,
So as to be mixed with new rubber, new rubber is manufactured, has the advantages that cost is low and free from environmental pollution with bacterial desulfurization,
But bacterial desulfurization method is time-consuming longer.
The content of the invention
In view of this, in view of the technical drawbacks of the prior art, it is an object of the present invention to provide a kind of useless
The renovation process of old tire.
To reach above-mentioned purpose, the present invention provides following technical scheme：
A kind of renovation process of junked tire, comprises the following steps：
（1）Waste old is cleaned, cuts glue, crushes, obtains rubber powder；
（2）Rubber powder, desulfurizing agent dibutyl disulfide and softening agent aliphatic acid are positioned in ultrasonic equipment, stirred,
Regulation ultrasonic power is 400w~800w, controls 40~70 DEG C of temperature, is reacted 4~8 minutes；
（3）After the completion of desulfurization, products therefrom is subjected to tabletting, obtains reclaimed rubber.
Further, the mesh number of rubber powder is 30~80 mesh in the step (1).
Further, the mass ratio of rubber powder, desulfurizing agent and softening agent is 25~50 in the step (2):1:0.2~1.
The beneficial effects of the present invention are：The present invention carries out desulfurization using the method for ultrasonic assistant desulfurizing agent, due to super
Sound wave good directionality, penetration capacity is strong, violent cavitation effect, shape will occur in liquid in ultrasonication solidliquid mixture
Into strong pressure pulses, accelerate solvent quick penetration compact tissue, improve desulfuration efficiency, while ultrasonic wave can accelerating medium molecule fortune
It is dynamic so that desulfurizing agent and waste rubber powder Rapid contact, mixing, system is fully reacted.Simultaneously as its operative temperature is low,
The shortcomings that avoiding high temperature from easily making carbon-to-carbon rupture, the hydraulic performance decline for making reclaimed rubber, desulfurization time is short, and desulfurized effect is good, reclaimed rubber
Function admirable.
