Description
Technical field
Patent of the present invention belongs to the production process and technique of activated rubber powder field more particularly to a kind of activated rubber powder.
Background technology
Existing is to comprehensively utilize waste old, can waste and old rubber be ground into shoddy and is added in sizing material
It recycles.But untreated shoddy is directly incorporated into sizing material, due to shoddy particle surface bumps not
It is flat, in burr shape, make matrigel in connection bad, can decline the physical mechanical property of sizing material；Also, it is incorporated into sizing material
The fineness of shoddy also determine the performance and purposes of made sizing material, the granularity of the shoddy of incorporation is smaller, made sizing material
Performance can be improved, but cost can increase therewith；And the granularity of the shoddy mixed is bigger, the performance of made sizing material
Also it glides therewith, it is also poorer with substitution effect to mix, and limits application of the shoddy in rubber.It therefore must be to scrap rubber
Powder is modified, and is changed the property of the particle of shoddy, is become modified glue powder, it is made to be used for as a kind of new robber materials
In rubber industry and building industry.Modified glue powder is added in sizing material, can not only reduce cost, can also improve processing performance,
Improve quality.Such as appropriately the sizing material of addition modified glue powder shrinking percentage in extrusion molding can reduce, the dimensionally stable of product；
Also, mobility can be improved in sulfidation, product improves qualification rate with modified glue powder without scar and bubble after vulcanization
Traditional reclaimed rubber is substituted, the production processes such as desulfurization, kneading, refining in reclaimed rubber production process can be saved, avoid the production
The sulfur dioxide gas generated in the process secondary pollution caused by environment, and it is possible to improve the dynamic property of sizing material.
At present, there are various methods to the modification of shoddy, principle is to have foot in the network structure for make original shoddy
Enough cross-bonds are broken to as rubber powder particle, while generate active group in rubber powder particle surface.

Problem.
The technical issues of patent of the present invention solves is realized using following technical scheme：A kind of making stream of activated rubber powder
Journey and technique, including waste Crumb rubber, plasticizer, interleaving agent, catalyst, dispersant, softening agent, activating agent, regenerative agent, according to weight
Number meter is measured, including following components：100 parts of waste Crumb rubber, 5-15 parts of softening agent, 0.3-2 parts of activating agent, 10-15 parts of interleaving agent,
0.5-1 parts of catalyst, 10-15 parts of plasticizer, 2-3 parts of dispersant, 2-3 parts of regenerative agent；By waste rubber powder and regenerative agent and activation
Agent in blender 30 DEG C -120 DEG C pretreatment 10min-600min after, add in double screw extruder, by controlling twin-screw
The temperature of different sections is at 120 DEG C -300 DEG C, and pressure is in 0-10Mpa, under the action of extruder screw, after reacting 1-15min
From screw extruder die extrusion, it is cooled to 80 DEG C hereinafter, can obtain in 1min-20min in 0-35 DEG C through cooling device
To prepared activated rubber powder.
Further, the source of waste Crumb rubber is one in radial tyre, car tire, sebific duct, conveyer belt, rubber overshoes, offset plate
Kind is several.
Further, the grain size that the waste Crumb rubber is is 20-40 mesh.
Further, the softening agent is one or more of coal tar, pine tar, tall oil, aromatic naphtha, rosin
Mixture.
Further, the activator is in thiophenol, thiophenol zinc salt, aromatic hydrocarbons disulphide, polyalkylbenzene phenol sulfides
One or more of mixtures.
