Li-resin tsa petroleum (hydrocarbon resin)
Petroleum resin ke sehlahisoa sa lik'hemik'hale se sa tsoa etsoa lilemong tsa morao tjena. E rehelletsoe ka mohloli oa lihlahisoa tsa petroleum. E na le litšoaneleho tsa boleng bo tlaase ba asiti, miscibility e ntle, ho hanyetsa metsi, ho hanyetsa ethanol le khanyetso ea lik'hemik'hale, le botsitso bo botle ba lik'hemik'hale ho acid le alkali. , 'me e na le phetoho e ntle ea viscosity le botsitso ba mocheso, theko e tlaase. Li-resin tsa peterole hangata ha li sebelisoe li le mong, empa li sebelisoa hammoho e le li-accelerator, li-regulator, li-modifiers le li-resin tse ling. E sebelisoa haholo ho rabara, likhomaretsi, liphahlo, pampiri, enke le liindasteri tse ling le masimong.
Ka kakaretso, e ka aroloa e le C5 aliphatic, C9 aromatic (aromatic hydrocarbons), DCPD (cycloaliphatic, cycloaliphatic) le monomers tse hloekileng tse kang poly SM, AMS (alpha methyl styrene) le mefuta e meng e mene ea lihlahisoa, limolek'hule tsa eona ke li-hydrocarbon kaofela. , kahoo e boetse e bitsoa hydrocarbon resin (HCR).
Ho ea ka lisebelisoa tse fapaneng tse tala, e arotsoe ka resin ea Asiatic (C5), alicyclic resin (DCPD), resin e nkhang hamonate (C9), aliphatic / aromatics copolymer resin (C5 / C9) le resin ea petroleum ea hydrogenated. C5 hydrogenated petroleum resin, C9 hydrogenated petroleum resin
Tse sebelisoang haholo ke tse
C9 petroleum resin ka ho khetheha e bua ka ntho e nang le boreleli e fumanoang ka "polymerizing olefins kapa cyclic ole fins kapa copolymerizing ka aldehydes, hydrocarbons e nkhang hamonate, terpenes, joalo-joalo." e nang le liathomo tse robong tsa carbon.
C9 petroleum resin, eo hape e tsejoang e le resin e nkhang hamonate, e arotsoe ka polymerization ea mocheso, polymerization e batang, tar joalo-joalo. Har'a tsona, sehlahisoa se batang sa polymerization se na le 'mala o bobebe, se setle ka boleng,' me se na le boima ba limolek'hule tse 2000-5000. Letlapa le bosehla bo bobebe ho isa ho bosootho bo bobebe, bo tiileng kapa bo boholo bo tiileng, bo bonaletsang ebile bo benya, boima bo amanang le 0.97 ~ 1.04.
Sebaka sa ho nolofatsa ke 80 ~ 140â. Mocheso oa phetoho ea khalase ke 81°C. Lenane la Refractive 1.512. Ntlha ea Flash 260 â. Boleng ba asiti 0.1~1.0. Theko ea iodine ke 30 ~ 120. E qhibiliha ka acetone, methyl ethyl ketone, cyclohexane, dichloroethane, ethyl acetate, toluene, peterole, joalo-joalo.
Ha e qhibilihe ka har'a ethanol le metsing. E na le sebopeho sa cyclic, e na le litlamo tse ling tse habeli, 'me e na le momahano e matla. Ha ho na lihlopha tsa polar kapa tse sebetsang mohahong oa limolek'hule ebile ha ho na lik'hemik'hale. E na le khanyetso e ntle ea asiti le alkali, e hanyetsa lik'hemik'hale le ho hanyetsa metsi.
Ho se mamelle hantle, ho brittleness, le ho se khone ho tsofala hantle, ha ea lokela ho sebelisoa e le mong. Ho lumellana hantle le resin ea phenolic, resin ea coumarone, resin ea terpene, SBR, SIS, empa e sa tsamaellane hantle le li-polymer tse seng polar ka lebaka la polarity e phahameng. E tukang mollo. Nontoxic.
Ka matla a eona a phahameng a ho ebola le ho tlamahane, ho sebetsa hantle ka potlako, ts'ebetso e tsitsitseng ea tlamahano, viscosity e itekanetseng ea ho qhibiliha, ho hanyetsa mocheso o motle, ho lumellana hantle le polymer matrix, le theko e tlaase, e ile ea qala ho fetola butle-butle resin ea tlhaho ho eketsa li-viscosity agents (rosin le terpene resin). ).
Litšobotsi tsa resin ea peterole ea C5 e hloekisitsoeng ka har'a likhomaretsi tse chesang tse qhibilihang: metsi a matle, a ka ntlafatsa ho koloba ha thepa ea mantlha, viscosity e ntle, le ts'ebetso e ikhethang ea pele. Lintho tse ntle tse khahlanong le botsofali, 'mala o bobebe, o hlakileng, o monko o fokolang, o fokolang. Likhomaretsing tse chesang tse qhibilihisang, letoto la ZC-1288D le ka sebelisoa le le mong e le resin ea tackifying kapa le kopantsoe le li-resin tse ling tsa tackifying ho ntlafatsa litšobotsi tse itseng tsa li-adhesive tse chesang tse qhibilihisang.
Sekhomaretsi sa ho qhibiliha se chesang:
Resin ea motheo ea sekhomaretsi se chesang se qhibilihisang ke ethylene le vinyl acetate copolymerized tlas'a mocheso o phahameng le khatello e phahameng, e leng resin ea EVA. Resin ena ke karolo e ka sehloohong ea ho etsa sekhomaretsi se chesang se qhibilihisang. Tekanyo le boleng ba resin ea motheo li khetholla thepa ea motheo ea sekhomaretsi se chesang se qhibilihisang.
Melt index (MI) 6-800, dikahare tse tlase tsa VA, ha crystallinity e phahame, boima bo phahameng, tlas'a maemo a ts'oanang, litaba tsa VA li kholoanyane, ho theola kristallinity, matla a phahameng a matla le mocheso o phahameng oa ho qhibiliha le tsona. e futsanehileng ka ho koloba le ho phunyeletsa ha tse khomarelang.
Ho e-na le hoo, haeba letšoao la ho qhibiliha le le leholo haholo, mocheso o qhibilihisang oa sekhomaretsi o tlaase, mokelikeli o motle, empa matla a ho kopanya a fokotsehile. Khetho ea li-additives tsa eona e lokela ho khetha tekanyo e nepahetseng ea ethylene le vinyl acetate.
