C9 and colophony of oil of C9 of distinction of C5 oil resinous are referred in particular to have group in order to include olefin of " of nine carbon atomic or annulus olefin or with aldehyde kind, the colophony sex matter that apperception of Xi of aromatic hydrocarbon, terpene adds up to the copolymerization such as content and becomes " . Accordingly, c9 oil colophony calls aromatic hydrocarbon oil colophony again, cent gets together for heat, the type such as Leng Ju, tar, among them color of Leng Jufa product shallow, quality is good, average member measures 2000~5000.
Can dissolve at ketone of acetone, Jia Yi, annulus ester of second of personal alkyl, 2 chloric ethane, acetic acid, toluene, benzine. Not dissolve is mixed at alcohol water. Polarity or function are not contained in molecular structure sexual radical is round, active without chemistry. Acid-proof alkaline, be able to bear or endure chemical sex, be able to bear or endure ability in swimming is good. Stick receive performance poorer, brittleness is big, ageing resistance not beautiful, unfavorable and alone use. Consistence of colophony of grand of colophony, as ancient as phenolic aldehyde horse, terpene Xi colophony, SBR, SIS is good. C5 oil colophony comes off with its stick receive strength tall, fast stickiness is good, stick receive viscosity of function stability, melt measurable, hear resistance is good, the consistence with high polymer matrix is good, begin to replace natural colophony to add adhesive stage by stage.
Liquidity is good, can improve the wetability of main body material, agglutinant good, have outstanding function is stuck first. Fight ageing sex admirably, color is light, transparent, low smelly, low volatile. Oil colophony can divide it is 4 kinds: C5 is adipose a group of things with common features, C9 is balmy a group of things with common features, double-loop the fifth of the ten Heavenly Stem forked colophony of 2 Xi annulus and get together the pure product such as SM, AMS. Oil colophony is entered makings is OK the fat of fat family tree that is differentiated to differ (C5) , fat of fat annulus family tree (DCPD) , aromatics colophony (C9) , adipose a group of things with common features / colophony of copolymer of scent a group of things with common features (C5 / C9) and hydrogenation oil colophony. Colophony of hydrogenation C5 oil, colophony of C9 hydrogenation oil.
