Description

Technical Field

[0001] The present invention relates to a synthetic rubber material, a method for preparing the synthetic rubber material, a process for preparing the synthetic rubber material, and applications of the synthetic rubber material, the method for preparing the synthetic rubber material, and the process for preparing the synthetic rubber material, and in particular relates to a cis-butylene-styrene integrated rubber, a method for preparing the cis-butylene-styrene integrated rubber, a process for preparing the cis-butylene-styrene integrated rubber, applications of the method for preparing the cis-butylene-styrene integrated rubber, applications of the process for preparing the cis-butylene-styrene integrated rubber, and applications of the cis-butylene-styrene integrated rubber; the cis-butylene-styrene integrated rubber is an integrated rubber or a special rubber. Background Art

[0002] Cis-1,4-butadiene rubber (CI-1,4-butadiene rubber) has excellent properties, including good elasticity, friction resistance, and low-temperature resistance, but poor wet-slip resistance. Styrene-butadiene rubber (SBR) has good wet-slip resistance, but relatively poor friction and low-temperature resistance, making it inferior to CI-1,4-butadiene rubber. The synthesis of CI-1,4-butadiene rubber involves the coordination polymerization of butadiene monomer using titanium, cobalt, nickel, or rare earth catalysts in the presence of cocatalysts such as alkylaluminum and BF3 etherate complexes, producing high-cis polybutadiene rubber. The active central atoms (Ti, Co, Ni, Nd, Pr, Ce, Y, etc.) of the titanium, cobalt, nickel, or rare earth catalysts simultaneously complex with the C1 and C4 atoms of the butadiene monomer to form large π bonds, resulting in a 1,4 polymerization reaction, producing high-cis polybutadiene rubber with a cis structure content exceeding 90%. While styrene can also undergo coordination polymerization to produce polystyrene under the action of a catalyst, the styrene molecule only has one double bond. The two carbon atoms, C1 and C2, on the double bond form a π bond with the active center atoms of a titanium, cobalt, nickel, or rare earth catalyst, leading to a 1,2 polymerization reaction to produce polystyrene. Because the coordination polymerization mechanism of butadiene differs from that of styrene, butadiene and styrene cannot be used to produce a butadiene-styrene copolymer through coordination polymerization. Even if butadiene and styrene are reacted in the same reactor, only a mixture of polybutadiene and polystyrene homopolymers is obtained.

[0003] The industry can produce various copolymers of butadiene and styrene through anionic polymerization using lithium-based initiators, including random and block copolymers. However, the butadiene monomer has a variety of structures within the polymer chain, with cis-containing monomers accounting for approximately 13-35%, trans-containing monomers for approximately 27-55%, vinyl monomers for approximately 12-57%, and styrene monomers for approximately 10-30%. Therefore, high-cis polybutadiene or high-cis butadiene-styrene copolymers cannot be produced through anionic polymerization.

[0004] The industry also has the use of high-cis polybutadiene and styrene-butadiene rubber blending, high-cis polybutadiene and styrene-butadiene rubber are mixed in an organic solvent according to a certain ratio to obtain a high-cis polybutadiene and styrene-butadiene rubber composite rubber. Although the advantages of the two rubbers can be blended together to a certain extent to obtain a composite rubber with improved wear resistance and wet-slip resistance, the two rubbers cannot be mixed at the molecular level by this simple mixing method, and phase separation easily occurs, resulting in unstable performance. Therefore, the preparation technology of the integrated rubber of cis-1,1-butadiene rubber and styrene-butadiene rubber is key. The inventor of the present invention, Huang Sihuang, has proposed a new production process, which adds a storage tank after the post-polymerization reactor of the high-cis polybutadiene rubber synthesis reactor, and then connects the anionic polymerization process of butadiene-styrene. Anionic copolymerization reaction occurs with the polybutadiene rubber molecules containing double bonds produced in the high-cis polybutadiene rubber synthesis reactor, achieving a cis-1,1-butadiene integrated rubber in which the polybutadiene rubber molecules and the styrene-butadiene rubber molecules are chemically bonded, producing an integrated rubber of high-cis polybutadiene rubber and styrene-butadiene rubber.

[0005] The present invention unexpectedly discovered that a storage tank is added after the post-polymerization reactor of the high-cis polybutadiene rubber synthesis reactor, the temperature is maintained constant and stirring is carried out to terminate the coordination polymerization reaction of butadiene, and then a butadiene-styrene solution anionic polymerization process is connected, styrene and anionic initiator are added, butadiene is replenished, and a polarity regulator is added to cause anionic copolymerization of butadiene, styrene, and polybutadiene rubber, and a butadiene-styrene-polybutadiene rubber copolymer is generated in situ in the high-cis polybutadiene rubber solution. A chain extender is added to the last polymerization reactor in the anionic polymerization process to prepare a cis-butylene-butadiene-styrene integrated rubber.

[0006] The accidental discovery of the present invention can also be used for the integrated synthesis of polymer materials of other two or more rubbers or other two or more resins or other two or more fibers; a storage tank is added after the EPDM post-polymerization kettle to maintain the temperature constant and stir, terminate the coordination polymerization reaction of EPDM, and then connect the butadiene styrene solution anionic polymerization process, or connect any other solution polymerization process to prepare EPDM rubber and styrene butadiene rubber integrated rubber; a storage tank is added after the POE polymerization kettle to maintain the operating temperature constant and stir the anionic polymerization process, terminate the coordination polymerization reaction of POE, and then connect the butadiene styrene solution anionic polymerization process, or connect any other solution polymerization process to prepare EPDM rubber and styrene butadiene rubber integrated rubber. A solution polymerization process is carried out to prepare POE elastomer styrene butadiene rubber integrated rubber; a storage tank is added after the post-polymerization kettle of the high-cis polybutadiene rubber synthesis kettle to maintain the operating temperature of the free radical polymerization process unchanged and stir, and then connect the acrylonitrile styrene melt method or solution method free radical polymerization process to produce high-cis butadiene rubber and SAN resin integrated rubber and plastic materials; a storage tank is added after the POE polymerization kettle to maintain the operating temperature of the melt method free radical polymerization process unchanged and stir, terminate the coordination polymerization reaction of POE, and then connect the butadiene acrylonitrile melt method or solution method free radical polymerization process, or connect any other solution polymerization process to produce POE elastomer nitrile butadiene rubber integrated rubber, etc. The present invention can smoothly prepare other rubber and rubber integrated rubber materials, rubber and resin integrated rubber and plastic materials, rubber and fiber integrated rubber and fiber materials, resin and resin integrated resin materials, resin and fiber integrated plastic and fiber materials or fiber and fiber integrated fiber materials; the polymerization process is a coordination polymerization process, anionic polymerization process, cationic polymerization process, free radical polymerization process, condensation polymerization process, ring-opening polymerization process or other polymerization process; the other rubbers, resins or fibers include but are not limited to the following materials: polyethylene, polypropylene, polystyrene, polyvinyl chloride, poly 1-butene (PB), ethylene / 1-octene copolymer (POE), ABS, ASA, HIPS, styrene / maleic anhydride copolymer (SMA), EPR, EPDM, NBR, HNBR, SBS, SIS, SEBS, SEIS, SIBR, ESBR, SSBR, IIR, IR, NR, BR, CR, PBE, PC, PET, PBT, polybutylene succinate (PBS), polybutylene succinate / adipate (PBSA), polybutylene adipate / terephthalate (PBAT), PA, PEK, PPO, PTMEG, HTPB, PU, ​​PTFE, PMMA, PVA, ACM, PPS, EVA, ethylene / MMA copolymer (EMMA), ethylene / methacrylic acid copolymer (EMAA), PHB, PTT, PEN, PCT, PLA, PAN, PBI, PBO, POM or unterminated POM, etc. Summary of the Invention
