Abstract
The present invention discloses a waste tire regeneration processing technology, including the steps of milling, desulfurization regenerating, kneading, refining and molding. The desulfurization regenerating step includes heated and pressurized desulfurization after adding an activator, a softener, a plasticizer and water to rubber powder obtained from the milling step. The raw materials in the desulfurization regenerating step include by weight: 100 parts of rubber powder, 0.1 to 1.2 parts of the activator, 15-20 parts of the softener, 2.3-4 parts of the plasticizer and 9-12 parts of water. The desulfurization temperature is 180 DEG C-199 DEG C, and the desulfurization pressure is 2.8 MPa-3.8 MPa. By optimizing the ratio of the additives, adjusting material reaction temperature and pressure, the technical indicators of the regenerated rubber are improved, production efficiency is improved and the production cost is reduced.
Description
Technical field
The invention belongs to the regenerated rubber production technical field, particularly relate to a kind of regeneration complete processing of junked tire.
Background technology
The gordian technique of junked tire regeneration is how the sulphur in the old rubber thoroughly to be taken off, and to recover the due elasticity of rubber and plasticity, allows reclaimed rubber can be re-used as the high-grade rubber products such as the new tire of raw material production or adhesive tape, realizes the recycle of resource.Existing whole-tyre reclaim generally adopts water/oil method tradition sulfur removal technology, being about to that rubber powder adds behind a certain amount of additive in temperature is that 160 ℃～180 ℃, pressure are that desulfurization was approximately carried out in pressurize in 6 hours in the digester of 1.8MPa～2.0 MPa, though the method can realize the regeneration of old rubber, but the production cycle is long, energy consumption is large, and the rubber technology index of output is low, obvious particle is arranged, poor processability, major part can only be as the stopping composition of rubber item, be unfavorable for the recycle of resource, economic benefit and social benefit are lower.
Summary of the invention
The purpose of this invention is to provide a kind of with short production cycle, energy consumption is low, and can Effective Raise the junked tire regeneration complete processing of regenerated rubber technical indicator.
The object of the present invention is achieved like this, this junked tire regeneration complete processing comprises powder process, desulfurization regeneration, kneading, refining and molding procedure, described desulfurization regeneration operation is to add the pressurization desulfurization of heating behind activator, tenderizer, softening agent and the water in the rubber powder that the powder process operation makes, the quality proportioning of rubber powder and additive is in the described desulfurization regeneration operation: 100 parts of rubber powders, 0.1～1.2 part in activator, 15～20 parts of tenderizers, 2.3～4 parts in softening agent, 9～12 parts in water.
Further, pack in the digester after described rubber powder and activator, tenderizer, softening agent and water is mixed in proportion and sealing, utilize thermal source that material temperature is heated to 180 ℃～199 ℃, the tank internal pressure rises to 2.8MPa～3.8 MPa, pressurize discharging after 2～3 hours.
Described activator is the 420 class activator, and described tenderizer is Stockholm tar, and described softening agent is rosin.
The granularity of the rubber powder that described junked tire makes is 30～40 orders.
Be provided with the whipping appts that can stir material in the described digester.
Described digester is jacketed vessel, is thermal oil in the chuck.
The present invention is by optimizing the proportioning of additive, adjust the material reaction temperature and pressure, can pull open more fast sulfide linkage, more fully reduce rubber powder Elastic reticulated structure, reduce the generation of cyclical sulfide, thereby it is thorough, homogeneous, meticulous without particle, viscosity is large, plasticity the is good high-quality reclaimed rubber that can substitute natural rubber to obtain desulfurization, simultaneously, by reducing the desulfurization dwell time, greatly improved production efficiency, reduced manufacturing cost.
