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 regenerated rubber production technical field, particularly relate to a kind of regeneration complete processing of junked tire.
Background technology
The gordian technique of Waste tire regeneration how thoroughly to be taken off by the sulphur in old rubber, 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, realize the recycle of resource.Existing whole-tyre reclaim generally adopts water/oil method tradition sulfur removal technology, after adding a certain amount of additive by rubber powder temperature be 160 DEG C ~ 180 DEG C, pressure be 1.8MPa ~ 2.0 MPa digester in pressurize within about 6 hours, carry out desulfurization, 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, there is obvious particle, poor processability, major part can only as the stopping composition of rubber item, be unfavorable for the recycle of resource, economic benefit and social benefit lower.
Summary of the invention
The object of this invention is to provide a kind of with short production cycle, energy consumption is low, and effectively can improve the Waste tire regeneration complete processing of regenerated rubber technical indicator.
The object of the present invention is achieved like this, this Waste tire regeneration complete processing comprises powder process, desulfurization regeneration, kneading, refining and molding procedure, described desulfurization regeneration operation is temperature-pressure desulfurization add activator, tenderizer, softening agent and water in the rubber powder that powder process operation is obtained after, in described desulfurization regeneration operation, the quality proportioning of rubber powder and additive is: rubber powder 100 parts, 0.1 ~ 1.2 part, activator, tenderizer 15 ~ 20 parts, 2.3 ~ 4 parts, softening agent, 9 ~ 12 parts, water.
Further, described rubber powder and activator, tenderizer, softening agent and water are mixed in proportion in rear loading digester and also close, utilize thermal source material temperature to be heated to 180 DEG C ~ 199 DEG C, tank internal pressure rises to 2.8MPa ~ 3.8 MPa, pressurize discharging after 2 ~ 3 hours.
Described activator is 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 obtains is 30 ~ 40 orders.
The whipping appts that can stir material is provided with in described digester.
Described digester is jacketed vessel, is thermal oil in chuck.
The present invention is by optimizing the proportioning of additive, adjustment material reaction temperature and pressure, sulfide linkage can be pulled open more fast, more fully reduce rubber powder Elastic reticulated structure, reduce the generation of cyclical sulfide, thus 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, substantially increasing production efficiency, reducing manufacturing cost.
