Abstract
The present invention relates to the technical field of rubber, and in particular relates to a rubber composition used for a car and truck tire steel wire belt bundle layer, the rubber composition is characterized in that, based on 100 parts by weight of natural rubber as a base, the rubber composition further comprises 30 to 70 parts by weight of carbon black, 4.5 to 12.0 parts by weight of resorcinol-formaldehyde resin, 4.5 to 6.5 parts by weight of insoluble sulfur and 0.4 to 1.2 parts by weight of a sulfenamide vulcanization accelerator. The belt bundle layer can be well adhered to a tire body, and the anti-aging property is good.
Description
Technical field
The present invention relates to a kind of field of rubber technology, specifically a kind of rubber combination for sedan-chair card tyre wire belt.
Background technology
As everyone knows, belt is the main stressed member of radial, decides the distortion of carcass to a great extent, and subjects the stress being about 60 ~ 75%.The bond properties of belt and carcass and ageing-resistant performance affect very large on radial use properties, therefore, be the key problem of radial composition design to its formulating of recipe.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned existing technical deficiency, a kind of rubber combination for sedan-chair card tyre wire belt is provided, the bond properties of belt and carcass and ageing-resistant performance good.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of rubber combination for sedan-chair card tyre wire belt, it is characterized in that, with the natural rubber of 100 weight parts for benchmark, also comprise the carbon black of 30 ~ 70 weight parts, 4.5 ~ 12.0 weight part resorcinol-formaldehyde resins, the insoluble sulfur of 4.5 ~ 6.5 weight parts, the sulfenamide vulcanization accelerator of 0.4 ~ 1.2 weight part.
As preferably, the described rubber combination for sedan-chair card tyre wire belt, with the rubber combination of 100 weight parts for benchmark, carbon black 35 weight part, resorcinol-formaldehyde resin 5.0 weight part, insoluble sulfur 6.0 weight part, sulfenamide vulcanization accelerator 1.15 weight part.
The invention has the beneficial effects as follows, the bond properties of belt and carcass and ageing-resistant performance good.
Embodiment
Below in conjunction with embodiment, the invention will be further described:
Rubber combination for belt of the present invention contains rubber components, carbon black, insoluble sulfur and vulcanization accelerator, and rubber components comprises natural rubber (NR), and NR is not particularly limited, and can use the NR be generally used in tire industry.
As for rubber components, except NR, its example has, such as, and cis-1,4-polybutadiene rubber (BR), styrene-butadiene rubber(SBR) (SBR), polyisoprene rubber (IR).But, consider tyre wire and the bond properties for the rubber combination of belt, the rubber components preferably only containing NR.
Carbon black is not particularly limited, can uses for those carbon blacks in tire industry.
With the rubber combination of 100 weight parts for benchmark, the content of carbon black is not less than 30 weight parts, is preferably not less than 35 weight parts.When the content of carbon black is lower than 30 weight part, enough strengthening the property can not be obtained.In addition, the content of carbon black is no more than 70 weight parts, preferably no more than 65 weight parts.When the content of carbon black is more than 70 weight part, the rolling resistance of tire increases thus makes fuel consumption quantitative change large.
The resorcinol-formaldehyde resin that the present invention uses is phenylethene modified product, and free Resorcinol content is 1-5%.As the SL3020 resin purchased from HongKongSinoLegendGroupLimited.
With the rubber combination of 100 weight parts for benchmark, the content of SL3020 resin is not less than 4.5 weight parts, is preferably not less than 5.0 weight parts.When the content of carbon black is lower than 4.5 weight part, enough bond propertiess can not be obtained.In addition, the content of carbon black is no more than 12.0 weight parts, preferably no more than 11.5 weight parts.When the content of carbon black is more than 12.0 weight part, belt viscosity is too large, easily produces bubble between cord.
Insoluble sulfur is not particularly limited, can uses for those insoluble sulfurs in tire industry.
With the rubber components of 100 weight parts for benchmark, the content of insoluble sulfur is no more than 6.5 weight parts, preferably more than 6.0 weight parts.When the content of insoluble sulfur is more than 6.5 weight part, the thermal destruction produced during rubber is travelled affects and hardens.In addition, the content of insoluble sulfur is not less than 4.5 weight parts, is preferably not less than 4.55 weight parts.When the content of insoluble sulfur is lower than 4.5 weight part, sulfuration is carried out insufficient, so not easily demonstrate enough rubbery intensities.
It has chemical compound lot to can be used as vulcanization accelerator, wherein, uses sulfenamide vulcanization accelerator, because can have stable suppression scorching characteristic and suitable vulcanization rate by rubber combination of preparing of use elastoprene.
The example of sulphenamide vulcanization accelerator has N cyclohexyl 2 benzothiazole sulfenamide, N-oxygen di-(ethylene)-2-[4-morpholinodithio sulphenamide, N, N-bis-cyclohexyls-2-[4-morpholinodithio sulphenamide.
With the rubber components of 100 weight parts for benchmark, the content of sulphenamide vulcanization accelerator is no more than 1.2 weight parts, preferably more than 1.15 weight parts.When the content of sulphenamide vulcanization accelerator is more than 1.2 weight part, sulfuration is carried out in SE curing system, so the stress relaxation after sulfuration is difficult.In addition, the content of sulphenamide vulcanization accelerator is not less than 0.4 weight part, is preferably not less than 0.45 weight part.When the content of sulphenamide vulcanization accelerator is lower than 0.4 weight part, vulcanization rate is too low, so not easily obtain enough rubbery intensities.
Of the present invention in the rubber combination of steel belt, except above-mentioned rubber components, carbon black, insoluble sulfur, vulcanization accelerator, according to circumstances need also can be suitable be mixed into for the various Synergist S-421 95s of tire industry, such as, adhesive agent, antioxidant, stearic acid and zinc oxide.
By conventional method, steel belt rubber combination of the present invention is used to prepare pneumatic tyre of the present invention.Namely, in the unvulcanized stage, rubber combination for steel belt of the present invention is rolled into wirecord fabric, be cut into steel belt, and on tyre building machine, itself and other tire sealant parts are forced together, then with usual method, its mold has been formed unvulcanized tire, then by the unvulcanized tire of heating and pressurizing in vulcanizer, thus obtained pneumatic tyre of the present invention.
