[Industrial Field of Application] The present invention relates to a halogen-containing rubber composition.
More specifically, the present invention relates to a halogen-containing rubber composition with improved scorch resistance. [Prior Art] Halogen-containing rubbers can be crosslinked using a sulfur-acid acceptor system combination, but the physical properties of the resulting crosslinked rubber are generally poor, and therefore a thiourea-acid acceptor system has been used. Ta. Further, in order to improve the physical properties of cross-linked rubber, a combination of triazine trithiol and acid acceptor system has been studied, but it cannot be put to practical use due to poor scorch properties. In this crosslinking system, triazinetrithiol can be replaced by its derivatives, such as 6-dibutylamino-1,3,5-triazine-2,4-dithiol, 6-dibutylamino-4-butylthio-6-
When mercapto-1,3,5-triazine or the like is used, the scorch resistance is further deteriorated. [Problems to be Solved by the Invention] The present inventor has devised a method for improving the scorch resistance of a triazinetrithiol-acid acceptor system that provides a crosslinked rubber exhibiting good physical properties, and imparting practicality to it. As a result of various studies, we found that the reason for this is that the degree of scorch resistance is greatly affected by the pH in the system of halogen-containing rubber compositions, and as a countermeasure, we developed reinforcing agents and/or fillers with adjusted pH. It has been found that such problems can be effectively solved by adding the above to the composition system. [Means for Solving the Problems] and [Operation] Accordingly, the present invention relates to a halogen-containing rubber composition with improved scorch resistance, and this halogen-containing rubber composition comprises a halogen-containing rubber, a crosslinking agent triazine, A reinforcing agent and/or filler whose pH is adjusted to a range of about 2 to 7 by graft polymerization of a vinyl monomer is added to a crosslinkable composition containing trithiol and an acid acceptor. It becomes. In halogen-containing rubber, the rubber is crosslinked through an abstraction reaction of the halogen, which serves as a crosslinking point, but when a triazine trithiol-acid acceptor system is used, the halogen at the crosslinking point is first dehalogenated with triazine trithiol. A hydrogenation reaction takes place, and if the halogen-containing rubber composition is acidic, the scorch time will be long; on the other hand, if the halogen-containing rubber composition is alkaline, the scorch time will be short. As described above, the scorch resistance depends on the PH of the rubber composition, and the PH (measured with a PH meter of a 4% aqueous suspension) is about 2 to 7, preferably about 3 to 6.
This can be improved by adding reinforcing agents and/or fillers adjusted to a range of . As such reinforcing agents, carbon black, white carbon, etc. are used, and as fillers, for example, celite, talc, calcium metasilicate, calcium carbonate, graphite, clay, etc. are preferably used, and each of these has its own specific characteristics. It has active groups, often reacts with each other when mixed with rubber, and also has its own unique PH. Adjustment of the PH of these reinforcing agents and/or fillers can be achieved by adding vinyl monomers therein, such as acrylic acid,
Methacrylic acid, 2-hydroxyethyl acrylate, 2-hydroxypropyl acrylate, 2-
This is done by graft polymerizing hydroxypropyl methacrylate or the like. Graft polymerization is carried out using heat, ultraviolet rays, radiation, etc. When radiation is used, for example, Co-
When irradiated with about 5 to 20 megarads of 60, an efficient grafting rate (about 5% by weight or more, preferably about 10% by weight) can be achieved.
above). It is believed that the carboxyl and hydroxyl groups contained in the vinyl monomer grafted to the reinforcing agent and/or filler control the PH of the rubber composition and the rate of the dehydrohalogenation reaction. It will be done. Examples of the halogen-containing rubber include chloroprene rubber, epichlorohydrin rubber, epichlorohydrin-ethylene oxide copolymer rubber, epichlorohydrin-allyl glycidyl ether copolymer rubber, epichlorohydrin-ethylene oxide-allyl glycidyl ether ternary copolymer rubber, and epichlorohydrin-propylene oxide. -Allyl glycidyl ether ternary copolymer rubber, chlorsulfon polyethylene, chlorinated polyethylene, chlorinated polybutyl, halogen-containing acrylic rubber, and the like. In addition, as acid acceptors used in combination with triazine trithiol as a component of the crosslinking system, zinc oxide, magnesium oxide, lead oxide, various carbonium salts and hydroxy salts, and even alkali metal salts of stearic acid are used. It will be done. [Effects of the Invention] The halogen-containing rubber composition according to the present invention has reinforcing agents and/or fillers added to adjust their pH, so that the crosslinked triazine trithiol-acid acceptor system Despite the use of scorch resistance, a significant improvement in scorch resistance is achieved, which, combined with the good physical properties of the crosslinked product, gives it excellent practical utility. [Example] Next, the present invention will be explained with reference to an example.
