Description
Technical field
The present invention relates to curing bag production field, in particular to a kind of preparation method of curing bag.
Background technique
Tire curing bladder has become one of widely applied tool in tire production manufacture, specifically, in tire sulphur
Before change, first green tire is set in outside tire curing bladder, then to the intracapsular superheated water or high temperature compressed of being filled with of vulcanized rubber
Gas makes tire curing bladder swell stretching, extension, supports green tire as interior mold, in superheated water or high temperature compressed gas etc.
Medium realizes the sulfidization molding of green tire by transmitting heat.
For the use temperature of tire curing bladder between 150~200 DEG C, internal medium mainly has superheated water, high-temperature high-pressure
Contracting gas.Preparing main sizing material used in curing bag is butyl rubber, this is primarily due to butyl rubber with excellent
Air-tightness, good heat-resisting, ageing-resistant, acid and alkali-resistance and low water absorbable energy.But since butyl rubber saturation degree is high, it is unsuitable for
Sulfur cross-linking is generally required and is vulcanized using resin curative systems, and curingprocess rate is slower；The product of same thickness, butyl rubber
Glue vulcanization time is two to three times of the unsaturated rubbers such as natural rubber, causes production efficiency low.
A kind of tire curing bladder is disclosed in CN102786746B, concrete component is as follows: butyl rubber 98~102
Part, 4.96~5.04 parts of zinc oxide, 0.9996~1.0004 part of stearic acid, 7.35~7.65 parts of curing resin, N220 carbon black
44.1~45.9 parts, 29.4~30.6 parts of N550 carbon black, 4.96~5.04 parts of castor oil, 0.735~0.765 part of stabilizer；It can
To increase the access times of capsule, extend the service life of capsule, and in embodiment, vulcanization time is in 40min or more.
All characteristics that neoprene and chlorinated scoline have butyl rubber intrinsic, while also there is curingprocess rate
Fastly, more resistant to series of advantages such as heat, rubber compound tense needs corresponding cooperation process systems, realizes co-vulcanization molding.
Summary of the invention
To solve deficiency in the prior art, the present invention provides a kind of preparation methods of curing bag, by vulcanization
The formula of capsule is designed, to shorten the vulcanization time of curing bag.
The technical solution adopted by the present invention is that a kind of preparation method of curing bag, component includes: neoprene 20~50
Part, 20~50 parts of butyl rubber, 20~50 parts of chlorinated scoline, 30~50 parts of carbon black, 4~8 parts of castor oil, zinc oxide 2~5
Part, 0~2 part of stearic acid, 2~4 parts of sulphur, 3~5 parts of curing resin, 1~3 part of promotor, 1~3 part of anti-aging agent；
Tire curing bladder the preparation method is as follows:
S1, first according to formula, weigh neoprene, butyl rubber, chlorinated scoline, carbon black, castor oil, zinc oxide,
Stearic acid, sulphur, curing resin, promotor, anti-aging agent are added in mixer and carry out mixing, obtain internal mixing film；
S2, it internal mixing film is put into open mill is kneaded, extruded sheet after mixing, film cooled to room temperature；
Sizing material is injected in mold by S3, the spout that the film extruded in S2 is added to injection vulcanizer, molding；
S4. it is arranged 170~190 DEG C of curing temperature, vulcanization time is completed in 8~15min, vulcanization, ejects curing bag.
Further, the promotor is promotor ZDC.
Further, the anti-aging agent is being used in combination for antioxidant D and antioxidant D NP.There are neoprene, fourth in curing bag
Base rubber, chlorinated scoline, single anti-aging agent effect is bad, has synergistic effect between two or more anti-aging agents sometimes, adopts
It takes anti-aging agent and uses measure.
Further, the curing resin is alkyl phenolic resin.Contain butyl rubber in curing bag, due to butyl rubber
The saturation degree of glue is higher, needs to select alkyl phenolic resin to make resin curative using resin curative systems.
Further, in S1, smelting temperature is 160~170 DEG C, and mixing time is 8~15min.
Further, in S2, melting temperature is 80~85 DEG C, and mixing time is 4~8min.
Further, injection temperature is 55~95 DEG C.
Compared with prior art, in the present invention in the formula of curing bag, with neoprene, butyl rubber, chlorinated butyl
Rubber is basic glue, and the cooperation process systems adaptable with neoprene, butyl rubber, chlorinated scoline are added, and is solved
It is between neoprene, butyl rubber, chlorinated scoline and use problem.Common sulphur fluidisation system cannot meet the present invention
The processing of middle formula, wherein butyl rubber needs resin curative systems, and neoprene needs to be oxidized the oxide of zinc or magnesia
Vulcanizing system.Beneficial effects of the present invention: vulcanization time can prepare the curing bag of function admirable between 8~15min,
Vulcanization process time is substantially reduced, production efficiency is improved.
