Method for preparing pitch having high softening point and pitch prepared by the method |
| abstract |
The method for producing a high softening point pitch having a softening point of 290 to 340 ° C or more according to the present invention is a vinyl polymer containing halogen capable of forming a polyaniline intermediate in heat treatment of a 1 to 4 ring alkyl aromatic condensation product of a benzene ring (PVC)) is charged and heat treated at a temperature range of 190 to 250 ° C and 350 to 390 ° C to react to produce a basic pitch of 30 to 120 ° C. Deg.] C to remove volatile components. The pitch produced according to the present invention is 30 to 60 weight% of a pitch of 3 to 4 rings alkyl aromatic condensates such as alkyl anthracene / phenanthrene and alkyl pyrene, compared with a pitch prepared by adding conventional heat treatment distillation or chlorine and bromine, Or more, and these condensates are linearly linked with benzyl or methylene to have a polymerized structure, and have molecular weights of 400 to 2000 amu (measured by Time of Flight Mass Spectroscopy) It contains more than 95% of the substance and has an average molecular weight of 720 amu. And exhibits non-Newtonian melt fluidity at an optical isotropic pitch, exhibiting a high yield stress of 100 to 300 Pa at a temperature higher by 50 ° C than the softening point. Therefore, it is particularly suitable for a negative electrode material for lithium ion batteries and a precursor for pitch carbon fibers Lt; / RTI > |
