Petroleum resins (hydrocarbon resin)
Petroleum resin ichangobva kugadzirwa kemikari chigadzirwa mumakore achangopfuura. Inotumidzwa zita rekwakabva petroleum derivatives. Iyo ine hunhu hwekuderera kweasidhi kukosha, zvakanaka miscibility, kusamira kwemvura, ethanol kuramba uye makemikari kuramba, uye yakanaka kugadzikana kwemakemikari kune acid uye alkali. , uye ine yakanaka viscosity kugadziriswa uye kupisa kugadzikana, mutengo wakaderera. Petroleum resins kazhinji haashandiswe ega, asi anoshandiswa pamwe chete seanomhanyisa, regulator, modifiers uye mamwe marekeni. Inoshandiswa zvakanyanya murabha, zvinonamira, machira, bepa, inki uye mamwe maindasitiri neminda.
Kazhinji, inogona kuverengerwa seC5 aliphatic, C9 inonhuwira (aromatic hydrocarbons), DCPD (cycloaliphatic, cycloaliphatic) uye yakachena monomers senge poly SM, AMS (alpha methyl styrene) uye mamwe mana mafomu ezvigadzirwa, Mamorekuru ayo anoumbwa ese mahydrocarbon. , saka inonziwo hydrocarbon resins (HCR).
Zvinoenderana neyakasiyana mbichana, yakakamurwa kuita Asiatic resin (C5), alicyclic resin (DCPD), inonhuhwirira resin (C9), aliphatic / inonhuhwirira copolymer resin (C5 / C9) uye hydrogenated petroleum resin. C5 hydrogenated petroleum resin, C9 hydrogenated petroleum resin
Iyo inonyanya kushandiswa ndeye
C9 petroleum resin inonyatso inoreva chinhu chinorasika chinowanikwa ne "polymerizing olefins kana cyclic ole fins kana copolymerizing ane aldehydes, anonhuwirira hydrocarbons, terpenes, nezvimwewo." ine maatomu ecarbon mapfumbamwe.
C9 petroleum resin, inozivikanwawo seanonhuwirira resin, yakakamurwa kuita thermal polymerization, inotonhora polymerization, tara zvichingodaro. Pakati pavo, chigadzirwa chinotonhora chepolymerization chakareruka muruvara, chakanaka mumhando, uye chine avhareji yemamorekuru huremu hwe2000-5000. Chiyero cheyero kusvika kuchiedza chebrown flake, granular kana yakakura yakasimba, yakajeka uye inopenya, hukama density 0.97 ~ 1.04.
Nzvimbo yekupfavisa ndeye 80 ~ 140â. Tembiricha yekuchinja kwegirazi i81°C. Refractive index 1.512. Flash point 260 â. Asidhi yakakosha 0.1~1.0. Iko kukosha kweiodine i30~120. Soluble muacetone, methyl ethyl ketone, cyclohexane, dichloroethane, ethyl acetate, toluene, peturu, nezvimwewo.
Insoluble mu ethanol nemvura. Iyo ine cyclic chimiro, ine zvimwe zviviri zvisungo, uye ine yakasimba kubatana. Iko hakuna mapoka epolar kana anoshanda muchimiro chemolecular uye hapana chemakemikari chiitiko. Iine yakanaka acid uye alkali kuramba, makemikari kuramba uye kudzivirira mvura.
Kusina kumira zvakanaka, brittleness, uye kushomeka kusakara kuchembera, haifanirwe kushandiswa chete. Kugarisana kwakanaka ne phenolic resin, coumarone resin, terpene resin, SBR, SIS, asi kusapindirana kwakashata nemapolymer asiri epolar nekuda kwepamusoro polarity. Inopisa moto. Nontoxic.
Nekusimba kwayo kwepamusoro uye kusimba kwekubatanidza, kukurumidza kukurumidza kukurumidza, kugadzikana kwekubatana kwekuita, kunyungudika kwakadzikama, kumira kwakanaka kwekupisa, kuenderana kwakanaka nepolymer matrix, uye mutengo wakaderera, yakatanga kutsiva resin yechisikigo zvishoma nezvishoma kuwedzera viscosity agents (rosin uye terpene resins. )
Hunhu hwakanatswa C5 petroleum resin mune inopisa inonyungudutsa adhesives: yakanaka fluidity, inogona kuvandudza kunyorova kwechinhu chikuru, yakanaka viscosity, uye yakasarudzika yekutanga tack kuita. Yakanakisa anti-kuchembera zvivakwa, ruvara rwakareruka, pachena, kunhuhwirira kwakaderera, kuderera kwakaderera. Mukupisa kunyunguduka kwakanamira, ZC-1288D yakatevedzana inogona kushandiswa yega sekutangisa resin kana kusanganiswa nemamwe marezeni ekugadzirisa mamwe maitiro eanopisa anonyungudusa adhesives.
Hot melt adhesive:
Iyo yakakosha resin yekupisa inonyungudika adhesive ndeye ethylene uye vinyl acetate copolymerized pasi pekushisa kwepamusoro uye kudzvanywa kwakanyanya, iyo EVA resin. Iyi resin ndiyo chikamu chikuru chekugadzira inopisa inonamatira inonamatira. Chiyero uye kunaka kweiyo resin yekutanga inotarisisa zvimiro zveiyo inopisa inonyungudutsa adhesive.
Melt index (MI) 6-800, yakaderera VA yemukati, iyo yakakwira iyo crystallinity, iyo yakakwira kuoma, pasi pemamiriro akafanana, iyo yakakura iyo VA yemukati, yakadzika iyo crystallinity, iyo inowedzera elastic Simba repamusoro uye yakanyanya kunyunguduka tembiricha zvakare. urombo mukunyorova uye kupera kwezvinonamatira.
Pane zvinopesana, kana iyo yakanyunguduka index yakakura kwazvo, kunyunguduka kweglue kwakaderera, iyo fluidity yakanaka, asi simba rekubatanidza rakaderedzwa. Kusarudzwa kwezvinowedzera zvayo kunofanira kusarudza chiyero chakakodzera che ethylene uye vinyl acetate.
Mamwe maapplication:
1. Pendi
Iyo pendi inonyanya kushandisa C9 petroleum resin, DCPD resin uye C5/C9 copolymer resin ine high softening point. Kuwedzera petroleum resin kune pendi kunogona kuwedzera kupenya kwepende, kunatsiridza kunamatira, kuoma, kupikisa asidhi uye alkali kuramba kwependi firimu.
2. Rubha
Rubha inonyanya kushandisa yakaderera kupfava poindi C5 petroleum resin, C5/C9 copolymer resin uye DCPD resin. Marezeni akadaro ane zvakanaka kunyungudika pamwe neakasikwa rabha zvimedu, uye haana simba guru pane vulcanization maitiro erabha. Kuwedzera petroleum resin kune rabha kunogona kuwedzera viscosity, kusimbisa uye kupfava. Kunyanya, kuwedzera kweC5 / C9 copolymer resin haigoni kungowedzera kunamatira pakati pezvimedu zverubha, asiwo kunatsiridza kusungirirwa pakati pezvimedu zverubha netambo. Inokodzera zvigadzirwa zverabha zvine zvinodiwa zvakanyanya senge matairi eradial.
3. Indasitiri yekunamatira
Petroleum resin ine kunaka kunamatira. Kuwedzera petroleum resin kune zvinonamira uye matepi anonzwa kumanikidza anogona kuvandudza simba rekunamira, asidi kuramba, alkali kuramba uye kuramba kwemvura kweanonamira, uye inogona kunyatso kudzikisa mutengo wekugadzira.
4. Ingi indasitiri
Petroleum resins
5. Coating industry
Zvipfeko zvezviratidzo zvemugwagwa uye mucherechedzo wemugwagwa, petroleum resin ine kunamatira kwakanaka kune kongiri kana asphalt pavement, uye ine yakanaka kupfeka kusagadzikana uye kusamira kwemvura, uye ine hukama hwakanaka neinorganic zvinhu, zviri nyore kupfeka, kunaka kwemamiriro ekunze kuramba,
Kurumidza kuomesa, kusimba kwakanyanya, uye kunogona kuvandudza muviri uye makemikari zvimiro zveiyo layer, kunatsiridza UV kuramba uye kuramba mamiriro ekunze. Petroleum resin mugwagwa wekumaka pendi iri kuita zvishoma nezvishoma, uye kudiwa kuri kuwedzera gore negore.
6. Vamwe
Resin ine imwe dhigirii rekusaturation uye inogona kushandiswa sebepa saizi agent, epurasitiki modifier, nezvimwe.
7.
Chengetedza munzvimbo ine mhepo, inotonhorera uye yakaoma. Nguva yekuchengetera kazhinji igore rimwe, uye inogona kushandiswa mushure megore kana ikapfuura ongororo.
