Abstract
A process for regenerating waste or used vulcanized rubber includes mixing the particles of vulcanized natural rubber, or synthetic rubber, or their mixture with LR-104 as activating agent, LA-78 as catalyst and LB-43 as modifier, stirring while activating modification for 7-10 min, cooling in water and pugging with nucleophile LP-7 in open mill for 7-10 min. The regenerated rubber can be vulcanized to become elastomer, which has tension strength of 13-18 MPa and elongation of 320-400%.
Description
The present invention relates to the processing of waste material, particularly the regeneration of waste rubber.
Waste rubber is become plastic by elastomerics, Here it is reclaimed rubber, this reclaimed rubber can be used as rubber raw materials, re-uses in rubber item.Tradition waste rubber renovation process is that waste Crumb rubber is broken into about 30 purpose rubber powders, sneaks into cheap oils to rubber powder again, under near 200 ℃ of high temperature and high pressure conditions, in special device, carries out the long period and handles, and then handle through the intense mechanical post-treatment.The shortcoming of these methods is that energy consumption is big, environment is had pollution, is that the cross-linked rubber regeneration effect of main body is poor to synthetical glue or synthetical glue, and the molecular weight of the molecular weight ratio rubber of the reclaimed rubber of producing is much lower, its molecular weight does not have rubber even like that yet, and its use is restricted.Entered since the seventies, people seek brand-new renovation process and replace traditional scrap rubber renovation process.The first is under normal temperature and pressure conditions, with chemistry or the chemical machinery method that combines; It two is, rubber powder is directly mixed or the novel method of chemical conversion treatment.But scrap rubber plasticizing regeneration effect is undesirable under the existing normal temperature and pressure, the post-treatment difficulty, and new method reclaimed rubber quality does not have breakthrough raising, and the new method reclaimed rubber quality that has also is lower than the quality of traditional method reclaimed rubber.Chinese invention patent application (application number 91106149.5) discloses a kind of dry catalytic regeneration technology of waste perdurens, adds tenderizer and catalyzer in the rubber powder about 30 orders, carries out desulphurization reaction, refining.This method need feed pressurized gas when the rubber powder pre-treatment, need feed rare gas element when in water cooler, cooling off after the rubber powder manipulation of regeneration, cooled rubber powder will be through refining, need to use special-purpose Sealing Arrangement in the production, processing condition require harsh, and the Main physical performance-tensile strength at yield of the damaged tire cross-linked rubber ground rubber of gained is not high, only is 8.0-9.5Mpa.
The purpose of this invention is to provide that a kind of technology is simple and direct under normal temperature and pressure conditions, save energy, pollution-free and product physicals and the good waste or used vulcanized rubber renovation process of processing characteristics.
Implementation method of the present invention is as follows:
Raw material is the micelle (4 order) of the cross-linked rubber of natural gum or synthetical glue or both mixtures, substantially not fibre-bearing and metallic impurity.
Above-mentioned micelle 100 weight parts; add in the mixing reactor; the agitator that starts in the mixing reactor stirs (the agitator stirring velocity can be 900-1000 rev/min); (the blade high speed rotating of agitator makes micelle be subjected to shearing force in reactor in the mixing reactor to make it give birth to the heat intensification; the effect of multiple power such as frictional force and surging force; its temperature was raised to the temperature range of the initial stage adding assistant of reaction requirement in 10-15 minute) when the micelle temperature is raised to 80-100 ℃ in the mixing reactor; under continuous agitation condition; add 7-10 weight part activator LR-104 and 0.5-1 weight part catalyzer LA-78 successively; the catalytic activation reaction of carrying out micelle fracture sulfur cross-linking point is after 2-3 minute; add 3-5 weight part properties-correcting agent LB-43 again; continue to stir and carry out activation modification reaction 5-7 minute, promptly finish micelle activation modification response procedures.
Micelle activation modification temperature of reaction is controlled at less than 80 ℃, greater than (temperature of reaction control can realize by feeding water coolant to reactor jacket) in 140 ℃ the scope.The activation modification reaction times was controlled at 7-10 minute.
After the reaction of micelle activation modification is finished; the reacted micelle of activation modification is entered (can feed water coolant toward the water cooler chuck cools off) in the watercooler; the agitator that starts watercooler stirs (the agitator stirring velocity can be 100-150 rev/min) cool to room temperature, makes activation modification micelle termination reaction.The activation modification micelle of cool to room temperature is discharged water cooler, (can select roll spacing is 0.1-0.3mm to deliver to opening rubber mixing machine, the roller temperature is 45 ± 5 ℃, the roller speed ratio is 1: 1.12) on, add nucleophilic reagent LP-7 mixing together 7-10 minute in the activation modification micelle of 100 weight parts than the ratio of the nucleophilic reagent LP-7 of 3-5 weight part, promptly make regenerated rubber.
The optimal activation modified-reaction temperature of micelle in mixing tank is 100-120 ℃.If temperature of reaction is lower than 80 ℃, activator, the properties-correcting agent molten phenomenon of part caking less then easily takes place, make the activation modification reaction not exclusively, influence the regenerated rubber physicals; If temperature of reaction surpasses 140 ℃, then strong chain-breaking reaction takes place in process, and the regenerated rubber physicals is descended significantly.
