MS adhesive inonyanya kuve neMS polymer, plasticizer, filler, uye zvinoshanda zvekuwedzera. Inotevera irondedzero yakadzama:
MS polymer:MS polymer ndiyo yekutanga chikamu cheMS adhesive. Musana wayo une flexible polyoxypropylene ether segments, ukuwo cheni dzayo dziri kumagumo-silyl groups ane capping functional groups. Ichi chimiro chemolecular chinopa MS adhesive yakaderera modulus, yakasimba kushushikana kuzorora, uye yakakwira elastic kupora, ichibvumira kuti ienderane nekuwedzera kwemajoini uye shear deformation inokonzerwa nemamiriro ekunze akadai sekuwedzera kwekupisa uye kuputika kwechimiro, mitoro yemhepo, kudengenyeka kwenyika, uye kugarisana kwakasiyana.
Plasticizer:Plasticizers muMS adhesive anowedzera fluidity, kuderedza kuoma, uye kugadzirisa modulus. Mapurasitiki akajairika anosanganisira dioctyl phthalate (DOP), dibenzyl phthalate (DCP), uye dibutyl phthalate (DBP). Zvisinei, zvakakosha kuziva kuti huwandu hweplasticizer hwakawedzerwa hunofanira kuva pakati. Huwandu hwakawandisa hunogona kukonzera kutama uye exudation, zvichikanganisa kuita kwechisimbiso.
Fillers:Mafirita muMS anonamira anoita sekusimbisa, achiwedzera iyo sealant simba. Semuyenzaniso, kana uchigadzira akajeka MS adhesives, chena kabhoni nhema (fumed silica) inowanzoshandiswa seinosimbisa filler.
Functional Additives:Zvokunamira zveMS zvinewo zvinowedzerwa zvinoshanda senge silane coupling agents, catalysts, anti-anti kuchembera, uye desiccant agents. Silane coupling agents vanoita sebhiriji pakati pechisimbiso uye substrate, kuvandudza kunamatira; catalysts inomhanyisa kuyambuka uye kurapa pane tembiricha yekamuri, kupfupisa nguva yekumisikidza uye nekupa yakanaka kuchengetedza kugadzikana; anti-zvekuchembera zvinosimudzira kuchembera kweMS; uye desiccant agents anopedza unyoro kubva muhurongwa, achivandudza chisimbiso chekuchengetedza kugadzikana.
MS adhesives inopawo yakanakisa kuita kwezvakatipoteredza. Nekuti iwo mabikiro makuru iresin, dioctyl acrylate, uye calcium powder, haana formaldehyde-hapana, benzene{2}hapana, anonyungudutsa-asina kunhuhwirira{4}}zvinoita kuti atarisike uye afarire vanhu{5}. MS adhesive inorapa zvakanyanya kuburikidza ne hydrolysis uye dealcoholization ye silane nehunyoro mumhepo, ichiteverwa ne condensation. Izvi zvinoita kuti ive hygroscopically inorapika inonamira. Iyo network yakagadzirwa mushure mekurapa inopa yakanakisa mamiriro ekunze, kuramba mvura, kuramba kuchembera, uye kusimba.
Pakazere, MS inonamira, ine yakasarudzika kuumbwa uye kuita kwayo, inobata chinzvimbo chakakosha mumusika wekuvaka sealant, inomiririra chizvarwa chitsva chekuvaka sealants.
