Petroleum resins (hydrocarbon cob)
Petroleum resin yog ib yam khoom tshiab tsim tshuaj nyob rau xyoo tas los no. Nws muaj npe tom qab qhov chaw ntawm cov roj av derivatives. Nws muaj cov yam ntxwv ntawm cov kua qaub qis, zoo miscibility, dej tsis kam, ethanol tsis kam thiab tshuaj tiv thaiv, thiab tshuaj lom neeg ruaj khov rau acid thiab alkali. , thiab muaj qhov zoo viscosity hloov thiab thermal stability, tus nqi qis. Petroleum resins feem ntau tsis siv ib leeg, tab sis yog siv ua ke ua accelerators, regulators, modifiers thiab lwm yam resins. Siv dav hauv roj hmab, nplaum, txheej, ntawv, number case thiab lwm yam lag luam thiab teb.
Feem ntau, nws tuaj yeem raug cais raws li C5 aliphatic, C9 aromatic (aromatic hydrocarbons), DCPD (cycloaliphatic, cycloaliphatic) thiab ntshiab monomers xws li poly SM, AMS (alpha methyl styrene) thiab lwm yam plaub hom khoom, Nws cov khoom molecules yog tag nrho cov hydrocarbons. , yog li nws tseem hu ua hydrocarbon resins (HCR).
Raws li cov khoom sib txawv, nws tau muab faib ua Asiatic resin (C5), alicyclic resin (DCPD), aromatic resin (C9), aliphatic / aromatic copolymer resin (C5 / C9) thiab hydrogenated petroleum resin. C5 hydrogenated petroleum cob, C9 hydrogenated roj av resin
Feem ntau siv yog
C9 roj av resin tshwj xeeb yog hais txog cov khoom siv resinous tau los ntawm "polymerizing olefins lossis cyclic ole fins lossis copolymerizing nrog aldehydes, aromatic hydrocarbons, terpenes, thiab lwm yam." muaj cuaj carbon atoms.
C9 roj av resin, tseem hu ua aromatic resin, muab faib ua thermal polymerization, txias polymerization, tar thiab lwm yam. Ntawm lawv, cov khoom siv polymerization txias yog lub teeb xim, zoo zoo, thiab muaj qhov nruab nrab molecular hnyav ntawm 2000-5000. Lub teeb daj rau lub teeb xim av flake, granular lossis loj heev, pob tshab thiab ci, txheeb ze ntom ntom 0.97 ~ 1.04.
Qhov taw tes softening yog 80 ~ 140â. Cov iav hloov pauv kub yog 81 ° C. Refractive Index 1.512. Flash point 260 â. Acid tus nqi 0.1 ~ 1.0. Tus nqi iodine yog 30 ~ 120. Soluble hauv acetone, methyl ethyl ketone, cyclohexane, dichloroethane, ethyl acetate, toluene, roj av, thiab lwm yam.
Insoluble hauv ethanol thiab dej. Nws muaj ib tug cyclic qauv, muaj ib co ob daim ntawv cog lus, thiab muaj zog cohesion. Tsis muaj polar lossis pawg ua haujlwm hauv cov qauv molecular thiab tsis muaj tshuaj lom neeg ua haujlwm. Nws muaj cov kua qaub thiab alkali tsis kam, tshuaj tiv thaiv thiab dej tsis kam.
Tsis zoo adhesion, brittleness, thiab tsis zoo aging kuj, nws yuav tsum tsis txhob siv ib leeg. Kev sib raug zoo nrog phenolic resin, coumarone resin, terpene resin, SBR, SIS, tab sis tsis zoo sib xws nrog cov tsis-polar polymers vim muaj polarity siab. Flamable. Tsis muaj tshuaj lom.
Nrog nws lub siab tev thiab kev sib raug zoo zog, zoo ceev tack, ruaj khov kev ua tau zoo, nruab nrab yaj viscosity, zoo tshav kub tsis kam, zoo compatibility nrog polymer matrix, thiab tus nqi qis, nws pib maj mam hloov tej yam ntuj tso resin kom viscosity agents (rosin thiab terpene resins. ).
Cov yam ntxwv ntawm refined C5 roj av resin nyob rau hauv kub yaj adhesives: zoo fluidity, muaj peev xwm txhim kho lub wettability ntawm cov khoom tseem ceeb, zoo viscosity, thiab zoo heev pib tack kev ua tau zoo. Cov khoom zoo heev los tiv thaiv kev laus, lub teeb xim, pob tshab, tsis muaj ntxhiab, tsis muaj volatiles. Hauv cov nplaum kub yaj, ZC-1288D series tuaj yeem siv ib leeg ua tackifying resin lossis tov nrog lwm cov tackifying resins los txhim kho qee yam ntawm cov nplaum kub yaj.
Kub yaj nplaum nplaum:
Lub hauv paus resin ntawm kub yaj nplaum yog ethylene thiab yas acetate copolymerized nyob rau hauv qhov kub thiab txias siab, uas yog EVA resin. Cov resin no yog cov khoom tseem ceeb rau kev ua kom kub yaj nplaum. Qhov kev faib ua feem thiab qhov zoo ntawm cov cob qhia yooj yim txiav txim siab cov yam ntxwv ntawm cov nplaum kub yaj.
Melt index (MI) 6-800, qis VA cov ntsiab lus, qhov siab dua crystallinity, siab dua qhov hardness, nyob rau hauv tib lub sijhawm, qhov ntau dua cov ntsiab lus VA, qhov qis dua cov crystallinity, qhov elasticity siab zog thiab siab melting kub kuj yog. tsis zoo nyob rau hauv wetting thiab permeability ntawm adherends.
Ntawm qhov tsis sib xws, yog tias lub melting Performance index loj dhau, qhov kub ntawm cov kua nplaum melting yog tsawg, qhov fluidity yog qhov zoo, tab sis lub zog sib txuas yog txo. Kev xaiv ntawm nws cov additives yuav tsum xaiv qhov tsim nyog piv ntawm ethylene thiab vinyl acetate.
Lwm yam kev siv:
1. Xim
Cov xim feem ntau yog siv C9 roj av resin, DCPD resin thiab C5 / C9 copolymer resin nrog siab softening point. Ntxiv roj av resin rau cov xim tuaj yeem ua rau cov xim zoo nkauj, txhim kho qhov adhesion, hardness, acid kuj thiab alkali tsis kam ntawm cov xim zaj duab xis.
2. Roj hmab
Cov roj hmab tsuas yog siv cov ntsiab lus qis qis C5 roj av resin, C5 / C9 copolymer resin thiab DCPD resin. Xws li cov resins muaj kev sib koom ua ke zoo nrog cov roj hmab ntuj, thiab tsis muaj kev cuam tshuam zoo rau cov txheej txheem vulcanization ntawm roj hmab. Ntxiv roj av resin rau roj hmab tuaj yeem ua kom viscosity, ntxiv dag zog thiab muag muag. Tshwj xeeb, qhov sib ntxiv ntawm C5 / C9 copolymer resin tuaj yeem tsis tsuas yog ua kom cov adhesion ntawm cov khoom siv roj hmab, tab sis kuj txhim kho cov adhesion ntawm cov roj hmab thiab cov hlua. Nws yog tsim rau cov khoom siv roj hmab nrog cov kev xav tau siab xws li cov log tsheb radial.
3. Adhesive kev lag luam
Petroleum resin muaj adhesion zoo. Ntxiv cov roj av resin rau cov nplaum thiab cov ntaub nplaum nplaum tuaj yeem txhim kho lub zog nplaum, acid tsis kam, alkali tsis kam thiab dej tsis kam ntawm cov nplaum, thiab tuaj yeem txo cov nqi tsim khoom.
4. Ink kev lag luam
Petroleum resins
5. Txheej kev lag luam
Coatings rau txoj kev kos npe thiab txoj kev cim, roj av resin muaj zoo adhesion rau pob zeb los yog asphalt pavement, thiab muaj zoo hnav tsis kam thiab dej tsis kam, thiab muaj zoo affinity nrog inorganic tshuaj, yooj yim rau lub tsho tiv no, zoo huab cua tsis kam,
Kev ziab sai, siab ruaj khov, thiab tuaj yeem txhim kho lub cev thiab tshuaj lom neeg ntawm txheej, txhim kho UV tiv thaiv thiab huab cua tsis kam. Petroleum resin txoj kev kos xim yog maj mam dhau los ua qhov tseem ceeb, thiab qhov kev thov tau nce zuj zus txhua xyoo.
6. Lwm tus
Resin muaj qee qhov tsis txaus ntseeg thiab tuaj yeem siv los ua tus neeg sawv cev ntawm daim ntawv, hloov kho yas, thiab lwm yam.
7.
Khaws rau hauv qhov chaw muaj cua, txias thiab qhuav ib puag ncig. Lub sijhawm khaws cia feem ntau yog ib xyoos, thiab nws tseem tuaj yeem siv tom qab ib xyoos yog tias nws dhau qhov kev tshuaj xyuas.
