Abstract
The invention provides a stretch-proof tire vulcanization capsule. The problem urgently needed to be solved is to prolong the service life of the tire vulcanization capsule at the same time of improving the heat conductivity of the tire vulcanization capsule. The stretch-proof tire vulcanization capsule comprises the following raw materials in parts by weight: 100 parts of butyl rubber, 3 to 5 parts of chloroprene rubber adhesive, 30 to 50 parts of carbon black N330, 1 to 3 parts of castor oil, 1 to 5 parts of peptizer, 0.5 to 1.5 parts of stearic acid, 5 to 10 parts of zinc oxide and 6 to 10 parts of resin. The invention is used for production of tire vulcanization capsules.
Description
Technical field
The present invention relates to a kind of raw material and proportioning of tire curing bladder, be specifically related to a kind of stretch-proof tire curing bladder.
Background technology
The effect of tire curing bladder mainly in tire vulcanization process inside fill compressed gas, inflated with nitrogen or fill superheated water etc., capsule has certain extension ratio when vulcanized tyre, capsule is the working conditions of repeatedly upholding.So uphold except height and also be subject to high temperature and resistance to oxidation situation work-ing life, the capsule use temperature is generally the 180-200 degree.The medium of contact mainly is superheated water, superheated vapour, pressurized air or nitrogen.The capsule of the very large especially oblique of capsule extension ratio type.The capsule formula mentality of designing is high temperature resistant, the high extension, and resistance to oxidation, the reductibility after high the extension is setafter break.High temperature resistant not reaching is exactly directly to cause lose the work-ing life of curing bag.Uphold and the setafter break consideration that is associated, uphold the too low work-ing life that diminishes.Uphold too high because stress relaxation is returned originality decline, so under the prerequisite that guarantees tensile yield, also will guarantee gum content, the intensity of cross-linking density and sizing material.If capsule can not very fast recovery may cause capsule discounting phenomenon after upholding.So capsule is exactly for high temperature resistant, high strength, the high extension, low setafter break is considered design.
Present passenger vehicle tyre curing bag, the center thickness minimum be 3.8MM, that maximum is 5.5MM, because the thickness of tire curing bladder is thicker, work-ing life is longer, but the ability of transferring heat is poorer, thin thickness, work-ing life is short, but the ability of transferring heat is better.Present domestic capsule company mostly adopts the isoprene-isobutylene rubber between the degree of unsaturation 1.5%-2%, adopts N220 or N330 as strengthening agent, adopts Viscotrol C as tenderizer, but because Viscotrol C affects intensity, the tensile yield of butyl.In addition Viscotrol C easily migration in high-temperature is so cause the ageing resistance of capsule to descend.Become problem in the urgent need to address so prolong the thermal conduction that can strengthen again tire curing bladder work-ing life simultaneously of tire curing bladder.
Summary of the invention
The objective of the invention is provides a kind of stretch-proof tire curing bladder for the problem of above-mentioned existence, by rational proportioning and complete processing, significantly improve the physicals of tire curing bladder, so that the thickness of tire curing bladder when dropping to 3.0mm its tensile strength improve 30%, tension set reduces by 60%.
Above-mentioned purpose is achieved through the following technical solutions:
The stretch-proof tire curing bladder, its raw material comprises: isoprene-isobutylene rubber, neoprene latex, carbon black N330, Viscotrol C, peptizer, stearic acid, zinc oxide, resin, the parts by weight of each component are: 100 parts of isoprene-isobutylene rubbers, neoprene latex 3-5 part, carbon black N330 30-50 part, Viscotrol C 1-3 part, peptizer 1-5 part, stearic acid 0.5-1.5 part, zinc oxide 5-10 part, resin 6-10 part.
Described stretch-proof tire curing bladder, described peptizer adopt even tackifying resin 40MS.
Beneficial effect:
1. the present invention is on the prescription basis of traditional butyl tire curing bladder, in order to improve the physicals of tire curing bladder, by test of many times, reduces the consumption of Viscotrol C, increases the filling part peptizer for the viscosity that prevents sizing material simultaneously.So that the center thickness of tire curing bladder when being designed to 3.0mm its tensile strength improve 30%, tension set reduces by 60%.Do not affect simultaneously the work-ing life of capsule, can not occur capsule in the use procedure and repeatedly stretch and the phenomenon of swell.
2. because the Viscotrol C molecular weight ratio is lower, be beneficial to processibility, tensile yield, the flowability of sizing material etc., but the Viscotrol C consumption can affect intensity, the tensile yield of isoprene-isobutylene rubber when excessive.But because molecular weight ratio is hanged down easily migration in high-temperature, so ageing resistance descends.The present invention determines through test of many times, and per 100 parts of isoprene-isobutylene rubbers adopt the proportioning of 1-3 part Viscotrol C, adopt simultaneously peptizer 1-5 part so that the physical and mechanical properties of tire curing bladder improves greatly.
3. peptizer of the present invention adopts even tackifying resin 40MS.Evenly tackifying resin 40MS can improve the mixing homogeneity of the rubber of opposed polarity and viscosity, it can be absorbed by rubber in mixing cycle very soon, low viscosity glue produces immediately relatively, therefore other additives also can be by short mix, aging for tire curing bladder, the flowability of sizing material, intensity, balance is accomplished in elongation etc.
4. the present invention can improve the thermal conduction of tire curing bladder, reduces the usage quantity of material, increases the work-ing life of product, can be tire enterprise and improves 8% production efficiency.
