Abstract
The invention relates to the field of rubber techniques, and concretely relates to a rubberized sizing composition for tyre bead rings. The rubberized sizing composition for tyre bead rings is characterized in that through taking 100 parts by weight of rubber component as reference, the rubberized sizing composition also comprises the following components in parts by weight: 30-100 parts of carbon black, no more than 3-16.5 parts of insoluble sulfur, and no more than 0.4-1.5 parts of a sulfenamide vulcanization accelerator, wherein the rubber component comprises 45-80 parts by weight of butadiene styrene rubber and 20-55 parts by weight of natural rubber. The rubberized sizing composition disclosed by the invention has the advantages that a pneumatic tyre using a bead ring prepared by using the composition is high in cutting resistance, and has small possibility of deformation.
Description
Technical field
The present invention relates to the rubber technology field, specifically a kind of bead wire ring kiss-coating sizing composition.
Background technology
As everyone knows, Steel Traveler is installed on the wheel rim, directly contacts with wheel rim.It need bear the expansion force that produces because of interior pressure, also need overcome tire simultaneously in the suffered transverse force effect when going of turning round, and makes that cover tire is unlikely deviates from wheel rim.It must have very high cutting resistance ability, is difficult for deforming.And the cutting resistance of the bond properties of Steel Traveler kiss-coating sizing material and steel wire and sizing material can be very big to the use properties influence of radial.Therefore, the compsn design to it is the key problem of radial compsn design.
Summary of the invention
The object of the invention is exactly in order to overcome the deficiency of above-mentioned prior art, a kind of bead wire ring kiss-coating sizing composition to be provided, and uses the pneumatic tyre of the Steel Traveler that said composition processes, have very high cutting resistance can, be difficult for deforming.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of bead wire ring kiss-coating sizing composition,
Rubber components with 100 weight parts is a benchmark, also comprises,
The carbon black of 30～100 weight parts,
The insoluble sulfur of 3～16.5 weight parts,
0.4 the sulfenamide vulcanization accelerator of～1.5 matter weight parts;
Wherein said rubber components comprises the styrene-butadiene rubber(SBR) and 20～55 parts by weight of natural rubber of 45～80 weight parts.
The invention has the beneficial effects as follows that the pneumatic tyre of the Steel Traveler that the use said composition is processed has very high cutting resistance ability, is difficult for deforming.
Embodiment
Below in conjunction with embodiment the present invention is done further description:
The rubber combination that is used for Steel Traveler of the present invention contains rubber components, carbon black, insoluble sulfur and vulcanization accelerator.
Rubber components comprises tree elastomer (NR) and styrene-butadiene rubber(SBR) (SBR).
NR is not special to be limited, and can use the NR that is generally used in the tire industry.
The content of NR in the rubber components is preferably and is not less than 20 weight parts, further is preferably and is not less than 25 weight parts.When the content of NR is lower than 20 weight parts, be difficult for obtaining enough viscosity.In addition, the content of NR is preferably and is no more than 55 weight parts, further is preferably and is no more than 50 weight parts.When the content of NR surpasses 55 weight parts, cause the content of butadiene-styrene rubber to reduce the enough cutting resistance abilities that are difficult for obtaining.
To styrene-butadiene rubber(SBR) (SBR), can use the SBR1502 that is generally used for tire industry.
The content of SBR in the rubber components is preferably and is not less than 45 weight parts, further is preferably and is not less than 50 weight parts.When the content of SBR is lower than 45 weight parts, be difficult for obtaining enough cutting resistance abilities.In addition, the content of SBR is preferably and is no more than 80 weight parts, further is preferably and is no more than 75 weight parts.When the content of SBR surpasses 80 weight parts, the enough viscosity that is difficult for obtaining.
As for rubber components, except that NR and SBR, its example has, for example, and cis-1,4-polybutadiene rubber (BR), polyisoprene rubber (IR).Yet, consider tyre wire and the bond properties that is used for the rubber combination of Steel Traveler, preferably only contain the rubber components of NR and SBR.
Do not limit carbon black is special, can use those carbon blacks that have been used for tire industry.
Rubber combination with 100 weight parts is a benchmark, and sooty content is not less than 30 weight parts, is preferably and is not less than 35 weight parts.When sooty content is lower than 30 weight parts, can not obtain enough strengthening the property.In addition, sooty content is no more than 100 weight parts, is preferably to be no more than 90 weight parts.When sooty content surpasses 100 weight parts, thereby the increase of the rolling resistance of tire makes the fuel consumption quantitative change big.
Do not limit insoluble sulfur is special, can use those insoluble sulfurs that have been used for tire industry.
Rubber components with 100 weight parts is a benchmark, and the content of insoluble sulfur is no more than 16.5 weight parts, preferably is no more than 16.0 weight parts.When the content of insoluble sulfur surpassed 16.5 weight parts, the thermal destruction that produces during rubber is gone influenced and hardens.In addition, the content of insoluble sulfur is not less than 3.0 weight parts, preferably is not less than 3.5 weight parts.When the content of insoluble sulfur was lower than 3.0 weight parts, sulfuration was carried out insufficient, so be difficult for demonstrating enough rubbery intensities.
It has chemical compound lot to can be used as vulcanization accelerator, wherein, uses the sulfenamide vulcanization accelerator, because can use the rubber combination of elastoprene preparation to have stable inhibition scorching characteristic and suitable vulcanization rate.
The example of sulphenamide vulcanization accelerator has N cyclohexyl 2 benzothiazole sulfenamide, N-oxygen di-(ethylene)-2-[4-morpholinodithio sulphenamide, N, N-two cyclohexyls-2-[4-morpholinodithio sulphenamide.
Rubber components with 100 weight parts is a benchmark, and the content of sulphenamide vulcanization accelerator is no more than 1.5 weight parts, preferably is no more than 1.45 weight parts.When the content of sulphenamide vulcanization accelerator surpassed 1.5 weight parts, sulfuration was carried out in the semi effcient vulcanization system, so the stress relaxation after the sulfuration is difficult.In addition, the content of sulphenamide vulcanization accelerator is not less than 0.4 weight part, preferably is not less than 0.45 weight part.When the content of sulphenamide vulcanization accelerator was lower than 0.4 weight part, vulcanization rate was low excessively, so be difficult for obtaining enough rubbery intensities.
At the rubber combination that is used for the Steel Traveler kiss-coating of the present invention; Except that above-mentioned rubber components, carbon black, insoluble sulfur, vulcanization accelerator; According to circumstances need also can be suitable sneak into the various Synergist S-421 95s that are used for tire industry, for example, adhesive agent, Triple Pressed Stearic Acid and zinc oxide.
Through method commonly used, use Steel Traveler kiss-coating of the present invention to prepare pneumatic tyre of the present invention with rubber combination.Promptly; At sulfurating stage not, the rubber combination that is used for the Steel Traveler kiss-coating of the present invention is covered glue on steel wire, produce Steel Traveler, force together with triangular rubber core and produce the Steel Traveler composite members; And on tyre building machine, itself and other tire sealant parts are forced together; Then its mold has been formed not vulcanized tyre,, thereby made pneumatic tyre of the present invention then through heating and pressurizing vulcanized tyre not in vulcanizer with usual method.
