Abstract
The present invention relates to tyre renewing technique, and is especially production process of cold retreading rubber. The production process includes the following steps: compounding material, mixing, extruding, sulfurizing, demolding, polishing and finishing. The present invention has the advantages of no high temperature ageing of tyre body, high utilization rate of tyre body, high sulfurizing pressure to result in high attachment, stable sulfurizing temperature and greatly raised wear resistance.
Description
Technical field
The present invention relates to a kind of tyre rebuilding technology, especially a kind of cold tyre retreading face manufacturing process.
Background technology
Tyre rebuilding mainly was that heat is turned over originally, promptly the tyre surface of the surface of tyre that has worn and torn was ground off, and sticked elastomeric compound then, put mould into and vulcanized again.Its shortcoming is that carcass is subjected to high temperature ageing again when sulfuration, promptly is subjected to high-temperature damage again, makes carcass can only renovate at most like this two to three times.Tyre surface after heat is turned in addition wears no resistance, and has only 1/3rd of new tire its service life.
Summary of the invention
In order to overcome the deficiency that above-mentioned hot tyre retreading face exists, the invention provides a cold manufacturing process of turning over tread rubber.
The technical scheme that realizes above-mentioned purpose is as follows: a kind of process of producing cold re-treading rubber, adopt following steps:
A. prepare burden: raw material are weighed up weight by prescription;
B. mixing: the raw material of weighing are mixed by technology in banbury, and the control melting temperature is used water quench again below 90 ℃, makes elastomeric compound;
C. extrude: the control extrusion temperature is below 80 ℃, and thickness is extruded desired thickness to elastomeric compound at 14～20mm on extruder;
D. sulfuration: 145～165 ℃ of control sulfide stress 13～15MPa, time time 20～30min, temperature, the film of extruding, the specific mould of packing into is put in the vulcanizing press and is vulcanized.
E. the demoulding: the adhesive tape that vulcanizates is taken off from mould;
F. polishing: coarse the polishing of the working face of tyre surface;
G. finished product: check, sign, packing and store.
The present invention has the following advantages:
1. carcass is not subjected to high temperature ageing, has protected carcass, makes the renovation increased frequency of tire, and the carcass utilization rate improves.
2. use the tyre surface of compression molding, the sulfide stress height, the sizing material adhesion force is big, and curing temperature is stable, and wearability improves greatly, and distance travelled meets or exceeds new tyre.
Description of drawings
Fig. 1 is a process chart of the present invention.
The specific embodiment
A kind of process of producing cold re-treading rubber, as shown in Figure 1, adopt following steps:
A. prepare burden: raw material are weighed up weight by prescription;
B. mixing: the raw material of weighing are mixed by technology in banbury, and the control melting temperature is used water quench again below 90 ℃, makes elastomeric compound;
C. extrude: the control extrusion temperature is below 80 ℃, and thickness is extruded desired thickness to elastomeric compound at 14～20mm on extruder;
D. sulfuration: 145～165 ℃ of control sulfide stress 13～15MPa, time time 20～30min, temperature, the film of extruding, the specific mould of packing into is put in the vulcanizing press and is vulcanized.
E. the demoulding: the adhesive tape that vulcanizates is taken off from mould;
F. polishing: coarse the polishing of the working face of tyre surface;
G. finished product: check, sign, packing and store.
