Abstract
The invention relates to a production process for tire curing bladders. The production process includes steps of (1), pouring butyl rubber, zinc oxide, stearic acid, curing resin, N220 carbon black, N550 carbon black, caster oil and stabilizers into an internal mill and then milling to obtain milled rubber materials; (2), filling the milled rubber materials into an open mill, mixing the milled rubber materials to discharge to obtain rubber sheets 10mm in thick and 50mm in width, and naturally cooling the rubber sheets to the room temperature; and (3), filling the rubber sheets into a screw of an injection press while keeping the temperature of the screw within the range of 70-80 DEG C, extruding the rubber sheets by the screw under the pressure ranging from 12 MPa to 18MPa, weighing the rubber sheets by a metering pump, feeding the rubber sheets into a mold cavity, holding the pressure ranging from 12MPa to 18MPa to perform injection curing for 42-48 minutes at a temperature ranging from 160 DEG C to 170 DWG C, and finally ejecting the formed bladders out of the mold cavity by the injection press after finishing curing. Service times of the bladders produced by the production process can be increased, service lives of the bladders can be prolonged, and quality of tires produced by the aid of the bladders can be improved remarkably.
Description
Technical field
The present invention relates to a kind of production technique of tire curing bladder, belong to the doughnut production technical field.
Background technology
Along with the continuous development of world car industry and the quick growth of global motorway, the kind of automobile is more and more, and travel speed is more and more faster, and is increasingly high to the quality requirements of tire, thereby also is more and more smart to the quality requirements of tire-mold.Tire curing bladder is the essential tool of vulcanization process during modern tire is produced.Tire curing bladder will stand some harsh operating conditions, comprises high temperature, subdues significantly, co-cure and vulcanizing agent move from unvulcanized tire base.Have very big influence to tire plant production efficiency the work-ing life of curing bag, and its effect of tire curing bladder mainly is that inside is filled compressed gas, inflated with nitrogen or filled superheated water etc. in tire vulcanization process, makes its extension, props up and press vulcanized tyre in the tire sealant embryogeny.
The use temperature of tire curing bladder is generally 180～200 ℃; The medium of contact mainly is superheated water, superheated vapour, pressurized air or nitrogen; And the extension ratio of tire curing bladder is very big, does not high temperature resistantly reach requirement and can directly cause lose the work-ing life of curing bag.Uphold and setafter break considerations that be associated, upholds the too low work-ing life that diminishes, uphold too high owing to stress relaxation is returned originality decline, so under the prerequisite of assurance tensile yield, also will guarantee gum content, the intensity of cross-linking density and sizing material.If capsule can not recover to cause capsule discounting phenomenon after upholding very soon.
To above working conditions, capsule formula should be from high temperature resistant, HS, and high the extension, design is considered in aspects such as low setafter break.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of tire curing bladder is provided, that this tire curing bladder has is high temperature resistant, HS, the high extension, the characteristics of low setafter break.
According to technical scheme provided by the invention, the production technique of said tire curing bladder adopts following process step, and the component ratio is counted by weight:
