Description
Technical field
The present invention relates to the rubber tyre field, relate in particular to a kind of carcass sizing material and compounding process and application.
Background technology
Generally, the rubber compounding of each parts of rubber tyre, material of main part is take the synthetic rubber of the natural rubber of dienes or dienes as main, therefore, and when the design vulcanization system, mostly be the sulfur cross-linking system, when vulcanization crosslinking, its cross-link bond mostly is single cross-link bond, as use half the most general effective and effective sulfur cross-linking system in tire formulation, when vulcanization crosslinking, its cross-link bond namely is single "-S
X-" key, (" X " wherein can be according to performance need, is the different numeral such as 1～6); The peroxide vulcanizing system of and for example using occasionally in the Rubber Parts prescription, its cross-link bond then are single "-C-C-" keys etc.
The IPN technology is to utilize the method for chemistry or physics, two or more the macromolecular chain of different properties, the different molecular structures macromolecular chain that interts and obtain that crosses one another is curled up mixed system, in the film or coating that is applied to make with solution method or emulsion method more, and for the viscoelastic macromolecular material of the height IPN technology of elastomeric material particularly, because material itself is solid-state, therefore, can not finish the IPN technology with solution method, emulsion method or approximate method.
Disclosed IPN technology is at present except at macromolecule membrane, have on the high-molecular coating outside the report on probation, because the technical difficulty of its complete processing and the unstable of performance, there are no any report of in tire formulation, using, major cause is, the IPN processing technology of open report must be passed through the solution osmose process, emulsion dispersion or approximate method are mutually intersected the fractionated polymer subchain of several different structures to intert and are made, and this intersection is interted only be Wu Li Chan around, and this manufacture method is the technique that impossible realize in the tire manufacturing is produced, because tire material all is solid material, be impossible use the solution osmose process under present manufacturing condition, emulsion dispersion or approximate method are processed.
The patent of relevant IPN is a lot, typical IPN patent, patent such as the people such as J. Ka Tehaoze invention " is produced the method for interpenetrating polymer networks IPN, IPN and uses thereof ", the technology that relates to is to be produced the silicone polymer of interpenetrating polymer networks by monomer polymerization with solvent method, and technology relates to is and the production method of tire without any related silicone polymer; The emerging patent that waits people's invention of Li Rong " interpenetrating(polymer)networks elastic composition and make the method for relevant elastomer product " and for example, the technology that relates to is to be produced the thermoplastic elastomer polymer of interpenetrating polymer networks by monomer polymerization with emulsion method, and what technology related to also is without any related a kind of method of producing thermoplastic elastomer with tire; Plum and for example. the patent " interpenetrating(polymer)networks and methods involving and composition " of the people such as Griffith, Li Fengfu invention, the technology that relates to is a kind of method for preparing hydrogel material, does not belong to the tire field; Thank for another example to the patent " multifunctional network interpenetrating composition " of people's inventions such as Hong Quan, the technology that relates to is a kind of tackiness agent with interpenetrating polymer networks, and is more irrelevant with tire technology.
The application of IPN technology on the high-polymer molecular film has more research and patent, and the application in tire formulation yet there are no any patent and report.Major cause is, the IPN processing technology of open report must get the mutual crossbar system of fractionated polymer subchain by solution osmose process, emulsion method or approximate method, and this method is the technique that impossible realize in the tire manufacturing is produced.
