Abstract
The invention relates to a steel wire bonding rubber composition and a preparation method thereof. The rubber composition comprises, by weight, 100 parts of natural rubber, 50-60 parts of carbon black, 5-10 parts of white carbon black, 0.5-1 part of a silane coupling agent, 5-10 parts of zinc oxide, 1-1.5 parts of cobalt boroacylate, 1.5-2 parts of resorcinol resin, 2-3 parts of HMMM, 2 parts of an antioxidant RD, 0.8-1.6 parts of a promoter, 0.2 parts of an anti-scorching agent CTP and 5-8 parts of insoluble sulfur. The preparation method is simpler than the prior art; and the rubber composition has the advantages of good bonding performance on steel wires after being vulcanized, and has very good bonding performances after heat ageing and wet heat ageing, so tire delamination is prevented, the service life of tires is prolonged, and the security of the tires is improved.
Description
Technical field
The present invention relates to a kind of steel wire adhesive rubber composition and method of making the same, be applied particularly to and manufacture the bonding of belt and carcass cord cord in tire process, belong to rubber tyre and manufacture field.
Background technology
Steel wire in tire is the main stressed member of tire, and steel wire and the bond properties of rubber are very big to the performance impact of tire, decide the service life of tire to a great extent, often occur the damaged tyres that the delamination of steel wire and rubber causes in tire used process.
The rubber composition rubber after curing being traditionally used for steel wire bonding has good bond properties with steel wire, but sizing material heat ageing, after hydrothermal aging, steel wire is remarkably decreased with the bond properties of rubber, such as Japanese invention patent " rubber composition " that application number is 200880126356.2, publication number is the Chinese invention patent " sizing compound formula that a kind of rubber bonds with coppered steel wire and preparation method thereof " of CN102964647A, publication number is the Chinese invention patent " a kind of steel wire functional rubber and all steel matrix formula and rubber compounding method " thereof of CN104109267A, all there is sizing material heat ageing in the rubber composition for steel wire bonding in appeal patent, the problem that after hydrothermal aging, the bond properties of steel wire and rubber is remarkably decreased.
The present invention is used for steel wire adhesive rubber composition and method of making the same by the one of independent research, compared with prior art, preparation technology of the present invention is easy, the sizing material prepared has good bond properties with steel wire after not only vulcanizing, and it is respectively provided with good bond properties after heat ageing, hydrothermal aging etc., it is possible to prevent tire delamination, improves Using Life of Tyre and safety.
Summary of the invention
It is an object of the invention to provide a kind of for steel wire adhesive rubber composition and method of making the same, this sizing material is made up of (following consumption is weight portion) following components: natural rubber, 100 parts；White carbon black, 50-60 part；White carbon, 5-10 part；Silane coupler, 0.5-1 part；Zinc oxide, 5-10 part；Cobalt boracylate, 1-1.5 part；Resorcinol resin, 1.5-2 part；HMMM, 2-3 part；Anti-aging agent RD, 2 parts；Accelerator, 0.8-1.6 part；Anti-scorching agent CTP, 0.2 part；Insoluble sulfuy, 5-8 part.
A kind of preparation method for steel wire adhesive rubber compositions provided by the invention, comprises the following steps:
Natural rubber except vulcanizing system and HMMM, white carbon black, white carbon and other composition various being added continuously to initial temperature be approximately in the closed mixing container of 60 DEG C, fill factor, curve factor is 65-75%, and rubber compounding temperature reaches unloading binder removal when 150-160 DEG C.
Reclaiming and cool down thus obtained sizing material, then joined by the sizing material that sulfur, accelerator, HMMM, first stage obtain in the closed mixing container of 30 DEG C, sizing material temperature reaches unloading binder removal when 100-110 DEG C.
Compared with prior art, preparation technology of the present invention is easy, having a good bond properties with steel wire after the rubber vulcanization prepared, and be respectively provided with good bond properties after over cure, heat ageing, hydrothermal aging etc., sizing material remains the performances such as good tensile property, compression heat generation simultaneously.
Detailed description of the invention
Below in conjunction with embodiment, the present invention will be further described, but the invention is not limited in these embodiments:
The three kinds of sizing materials (A, B, C) manufactured according to this technological invention and a kind of comparison sizing material (D), and the physical and mechanical properties of contrast test sizing material, concrete formula is in Table 1.
Following calendering process is used to prepare the sizing material described in example: the natural rubber except vulcanizing system and HMMM, white carbon black, white carbon and other composition various to be added continuously to initial temperature and is approximately in the closed mixing container of 60 DEG C, fill factor, curve factor is 70%, and rubber compounding temperature reaches unloading binder removal when 155 DEG C.
Reclaiming and cool down thus obtained sizing material, then joined by the sizing material that sulfur, accelerator, HMMM, first stage obtain in the closed mixing container of 30 DEG C, sizing material temperature reaches unloading binder removal when 105 DEG C.
Preparing sizing material according to above-mentioned calendering process, and test the performances such as sizing material hot strength, compression heat generation, bonding extraction force, test result is in Table 2.
