Abstract
The invention relates to the technical field of rubber, and in particular relates to a fabric rubber composition of a semisteel radial tyre polyester cord. Taking 100 parts of rubber component as standard by weight, the rubber composition also comprises the following raw materials in part by weight: 30-70 parts of carbon black, 2.5-3.5 parts of insoluble sulfur, and 0.5-1.8 parts of sulfonamide-type accelerator, wherein the rubber component comprises 50-80 parts of natural rubber by weight and 20-50 parts of butadiene styrene rubber by weight. According to the invention, the good bonding performance and aging resistant performance of the tyre body cord fabric and other components can be ensured.
Description
Technical field
The present invention relates to the rubber technology field, specifically a kind of semi-steel radial tire polyester cord body rubber combination.
Background technology
As everyone knows, cord is mainly used in the framework material of tire.Performances such as cord must have the intensity height, and antifatigue is shock-resistant, and elongation is low, and heat-resistant stability is good, and is good with adhesion rubber property, ageing-resistant.Cord commonly used has the polyamide fibre cord, polyester cord, aramid fiber cord and wirecord fabric etc.When selecting cord for use, according to the structure properties of product, generally select the 1300D/2E0 polyester cord for use, but the bond properties of carcass cord and miscellaneous part and ageing-resistant performance not very desirable.
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 semi-steel radial tire polyester cord body rubber combination to be provided, can guaranteeing that the bond properties of carcass cord and miscellaneous part and ageing-resistant performance are good.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of semi-steel radial tire polyester cord body rubber combination,
Rubber components with 100 weight parts is a benchmark, also comprises,
The carbon black of 30～70 weight parts,
2.5 the insoluble sulfur of～3.5 weight parts,
0.5 the sulfenamide vulcanization accelerator of～1.8 weight parts;
Wherein said rubber components comprises the styrene-butadiene rubber(SBR) of 50～80 parts by weight of natural rubber and 20～50 weight parts.
The invention has the beneficial effects as follows, can guarantee that the bond properties of carcass cord and miscellaneous part and ageing-resistant performance are good.
Embodiment
Below in conjunction with embodiment the present invention is done further description:
The rubber combination that is used for cord body of the present invention contains polymer substance and pharmaceutical chemicalss such as 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.
Consider polyester cord and the bond properties and the stability to aging that are used for the rubber combination of cord body among the present invention, choosing contains the NR of 60-80 quality % content and the SBR rubber components of 20-50 quality % content.
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 70 weight parts, is preferably to be no more than 65 weight parts.When sooty content surpasses 70 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 4.0 weight parts, preferably is no more than 3.5 weight parts.When the content of insoluble sulfur surpasses 4.0 weight parts, cause using the material sulfuring up of this prescription easily; In addition, not low 2.5 weight parts of the content of insoluble sulfur preferably are not less than 2.0 weight parts.When the content of insoluble sulfur was lower than 2.0 weight parts, sulfuration was carried out insufficient, with the physical strength performance that has a strong impact on sizing material.
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 1.8 weight parts, preferably is no more than 1.75 weight parts.When the content of sulphenamide vulcanization accelerator surpasses 1.8 weight parts, vulcanization rate will reduce, and influence the sulfuration efficient of finished tire.In addition, the content of sulphenamide vulcanization accelerator is not less than 0.52 weight part, preferably is not less than 0.5 weight part.When the content of sulphenamide vulcanization accelerator is lower than 0.5 weight part, vulcanization rate will reduce, and influence the sulfuration efficient of finished tire.
At the rubber combination that is used for cord body 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, inhibitor, Triple Pressed Stearic Acid and zinc oxide etc.
Through method commonly used, use cord body 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 cord body of the present invention is rolled into cord, and severing becomes qualified cord and on tyre building machine, itself and other tire sealant parts is forced together according to structural requirement, then with usual method its mold has been formed not vulcanized tyre; Then through heating and pressurizing vulcanized tyre not in vulcanizer, thereby make pneumatic tyre of the present invention.
