In order to meet the requirements of the rubber industry and assist the development of green tires and rubber products with long service life, trans-butyl-pentyl rubber is produced at the same time.
Patent CN103387641A reports that a supported titanium catalyst system bulk polymerization technology is adopted to catalyze isoprene and butadiene monomer copolymerization to prepare trans-butadiene rubber with high trans-1, 4-structure content. In 2017, a tread rubber of a truck tire prepared by combining trans-butadiene-isoprene rubber and natural rubber has excellent fatigue resistance, wear resistance and low rolling resistance and heat generation, and is reported by university of Qingdao science and technology (Nature science edition). In 2018, the passenger car tire tread rubber prepared by combining trans-butyl-pentyl rubber, solution-polymerized styrene-butadiene rubber and cis-butyl rubber has excellent fatigue resistance and wet-skid resistance, and the patent CN 107814994A reports that the reclaimed rubber modified by the trans-butyl-pentyl rubber has very excellent comprehensive performance. In 2018, the national development and improvement committee lists trans-butyl rubber as high-quality synthetic rubber in 'strategic emerging key products and service guide catalogues', and a large number of materials report that tires and shock absorption products containing the trans-butyl rubber have very excellent comprehensive performance, but the research on the synthetic modification of the trans-butyl rubber is less.
The oil-extended modification can improve the processability of rubber, has low cost and is easy to realize industrialization, and the oil-extended modification of the rubber at present mainly focuses on the production process of solution polymerized styrene-butadiene rubber and ethylene propylene rubber. This patent reports for the first time the preparation of trans-butadiene-isoprene rubber/extender oil composites and their use.

Prepared trans-butyl/filled rubberThe oil composite was named OTBIR-2.
The processing performance of the trans-butadiene-isoprene rubber/filling oil composite material is researched by adopting a capillary rheometer, wherein the molar content of a butadiene structural unit is 35%, the molar content of an isoprene structural unit is 65%, and the Mooney viscosity ML is3+4 100℃The shear viscosity-shear rate curve for a trans-butyl rubber of 90 (TBIR-1) and the trans-butyl rubber/extender oil composite OTBIR-1 prepared in example 1, as well as the molar content of butadiene structural units of 10%, the molar content of isoprene structural units of 90%, and the Mooney viscosity ML3+4 100℃The shear viscosity vs. shear rate curve for trans-butyl rubber 120 (TBIR-2) versus trans-butyl rubber/extender oil composite OTBIR-2 prepared in example 2 is shown in FIG. 1.

Filling oil: trans-butyl rubber: 2, 6-di-tert-butyl-4-methylphenol as 100: 70: 0.7, adopting a single screw extruder to prepare the trans-butyl-pentyl rubber/filling oil composite material, wherein the screw rotation speed is 20 revolutions per minute, and the time is 6 minutes.

The filling oil is viscous and flowing at normal temperature, and the stiffness is too poor to be packaged by a plastic film; the viscosity of the product is greatly influenced by the temperature, and the product is difficult to pour and weigh at low room temperature. In order to endow the filling oil chamber with better stiffness at room temperature, a crystalline rubber material and the filling oil are used together to prepare a conforming material with good stiffness at room temperature. The trans-butyl-pentyl rubber/filling oil composite materials prepared in the embodiments 3 and 4 have good stiffness and dimensional stability at room temperature, are packaged into 2 Kg/bag or 5 Kg/bag by using a plastic film, and are directly put into an internal mixer when used in the fields of tires and non-tire rubber products.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
