Technical Field
The invention relates to the technical field of tire bead inserts, in particular to an all-steel tire bead insert and a preparation method thereof.
Background
The tire bead is a part for tightly fixing the outer tire and the rim, is required to have high strength and rigidity, bears the interaction force between the outer tire and the rim, resists external force when a vehicle runs, prevents the tire bead from being separated from the rim, and bears extremely strong and repeated torsional shearing force under severe running conditions, so that the separation between a tire steel wire and a steel wire rubber clamp is caused, the service life of the tire and the running safety are influenced, and the improvement of the adhesive force and the heat generation of rubber and the steel wire are very important for ensuring the service life of the tire.
Chinese patent application CN200810046577.0 discloses a steel wire sandwiched rubber material, the technical scheme provides a steel wire sandwiched rubber material containing iron oxide red, cobalt salt, high zinc oxide and high sulfur, the steel wire sandwiched rubber material can obviously improve the adhesion between steel wire and rubber, and reduce the separation phenomenon between the steel wire sandwiched rubber material and steel wire of finished oblique-ply tire and semi-steel tire, in heavy-duty products, the tire bead part bears large acting force, the ring part is repeatedly bent and deformed to generate a large amount of heat accumulation, and the ring part is easily damaged, therefore, although the above patent application strengthens the adhesion between rubber material and steel wire by adding cobalt salt and resin reinforced rubber material, the influence factor of the damage to the steel wire and rubber material interface layer due to heat generation is not considered.
The inventor initially tries to combine trans-isoprene rubber with natural rubber and styrene butadiene rubber to prepare the low-heat-generation all-steel tire bead filler, but the difference between the trans-isoprene rubber and the rubber such as natural rubber in molecular structure and physical property, so that the complete blending and co-vulcanization of trans-isoprene rubber and non-crystalline rubber such as natural rubber become difficult problems, while achieving high blending and co-vulcanization of two or more polymeric materials is a prerequisite for achieving low heat buildup performance of the polymeric composite material, the inventors even once abandoned the initial efforts for preparing all-steel tire bead fillers, however, as tests progress, the inventors unexpectedly found that, by using a suitable amount of sulfur in combination with trans-isoprene rubber and other components, the blended composition achieves high blending dispersion and co-vulcanization effects and can maximize the low heat buildup performance of the polymeric composite material. In conclusion, the all-steel tire bead filler with the new formula is provided, the self-heating of the rubber material is reduced, the shear resistance is improved, and the all-steel tire bead filler has important significance.
Disclosure of Invention
The invention provides a tire bead steel wire glue formula, aiming at solving the technical problems of high self-heating and poor shearing resistance of a rubber material of a tire bead clamp glue in the prior art.
In order to solve the technical problems, the invention adopts the following technical scheme:
the low-heat-generation all-steel tire bead insert comprises, by weight, 0.0-40.0 parts of natural rubber, 5.0-20.0 parts of trans-isoprene rubber, 50.0-80.0 parts of styrene butadiene rubber, 10.0-30.0 parts of sulfur, and other components including 80.0-120.0 parts of carbon black, 0.5-2.5 parts of stearic acid, 1.0-5.0 parts of zinc oxide, 1.0-3.0 parts of a homogenizing agent, 0.5-2.0 parts of an anti-aging agent RD, 1.0-10.0 parts of tackifying resin, 10.0-25.0 parts of rubber operating oil and 0.6-1.2 parts of thiazole accelerator.
The difference of molecular structure and physical property between trans-isoprene rubber and natural rubber makes the trans-isoprene rubber and natural rubber be difficult to be blended completely, and the high blending of two or more than two high molecular materials is the premise of obtaining low heat-generating property of high molecular composite material, compared with other vulcanized rubber, the trans-isoprene rubber is easy to crystallize at normal temperature and is a crystalline thermoplastic plastic, the inventor finds that when the sulfur dosage in the formula is proper, the cross-linking degree of the trans-isoprene rubber system is very high, the trans-isoprene rubber system can be changed into an amorphous cross-linking network, when the cross-linking degree of the trans-isoprene rubber of the hard elastomer is increased to a critical value, the molecular chain cross-linking points are dense, the molecular chain segment movement is difficult, the hard trans-isoprene rubber thermal elastomer is changed into a soft elastomer, and the soft trans-isoprene rubber elastomer formed under the cross-linking degree has excellent fatigue resistance, low dynamic heat generation and other excellent performances, and under the condition that the cross-linking degree of a trans-isoprene rubber system is very high, two or more than two polymer materials can be highly blended and cross-linked, and the trans-isoprene rubber and various raw and auxiliary materials can be co-crosslinked.
Secondly, the copper plating on the surface of the steel wire ring can generate cross linking only by the participation of sulfur, so that the mutual adhesion of the interfaces of the two materials is ensured, if the interface adhesion is not good, the cross-linked bond is less, the H extraction force is low, and the rubber and the steel wire ring can be separated early, so that the service life of the tire is influenced, therefore, one part of the sulfur provided by the invention is cross-linked with the copper plating, and the early separation between the rubber and the steel wire ring is prevented.
According to the formula of the tire bead insert rubber, a proper amount of sulfur is added in the formula, so that the requirements of high definite elongation and high hardness are met, the bonding performance of rubber and a steel wire is optimal, the purpose of completely crosslinking trans-isoprene rubber is achieved by matching with the use of a trans-isoprene rubber material, the trans-isoprene rubber is completely crosslinked, the heat generation of rubber materials is reduced, and the performance advantages of the trans-isoprene rubber are exerted to the maximum extent.
The carbon is N660 carbon black or N550 carbon black, and the homogenizing agent is selected from Shandong Yanggu Huatai chemical industry Co., Ltd, HT88 product; the tackifying resin is selected from products of Qingdao Crohn chemical Co., Ltd, YH 1288; the rubber operating oil is selected from V500 environment-friendly aromatic oil from Hansen company of Germany; the thiazole accelerant is dibenzothiazyl disulfide, DM for short.
Preferably, the carbon black is low-structure carbon black, preferably N660 carbon black or N550 carbon black, the dosage is high, preferably 80.0-120.0 parts by weight, the purpose is to improve the tensile stress and modulus of the rubber compound, and the carbon black with large particle size is beneficial to further reducing heat generation.
The invention also provides a preparation method of the low-heat-generation all-steel tire bead insert, which specifically comprises the following steps:
