I-Dimethyldiethoxysilane iba ngundoqo ekwenzeni i-silicone resin

I-resin yeglasi ye-silicone kunye ne-adhesive ye-silicone echasene nobushushu obuphezulu.

U-Huo Changshun kunye no-Chen Rufeng be-Chenguang Chemical Research Institute, i-Ofisi yoShishino lwemichiza, njl.Ngasekupheleni kweminyaka yee-1970, i-cts-103 silicone resin, eyaziwa ngokuba yi "silicone glass resin", yaphuhliswa ngempumelelo yi-hydropolycondensation ye-methyltriethoxysilane phambi kwe-acid catalyst.I-resin yayisetyenziselwa unyango lwephepha eliphambili, ukukhuselwa komgangatho wetsimbi, kunye nokudibanisa kwe-mica sheet okanye i-mica powder kwinqanaba lokuqala.Ngo-1980, i-Sanhua, i-Xue Zhiqing kunye no-Li Yansheng, abavelisi be-resin e-Shanghai, ngokulandelelanayo, basebenzisa i-resin yotshintshiselwano eqinileyo njenge-acid yethutyana.I-resin ye-silicone ecacileyo kunye ne-resistant-resistant-resistant ye-sar-1 kunye ne-sar-2 yenziwe ngokudibanisa inani elincinci le-dimethyldiethoxysilane kwi-monomethyltriethoxysilane ephambili.Ayikho i-asidi ye-inorganic acid eseleyo kwi-resin, ngoko ke ukusebenza kokugcinwa kwemveliso kuzinzile kakhulu, kwaye akukho cementation efunyenwe emva konyaka.Ngenxa yokuqaliswa kwezinto ezincinci ezingasebenziyo, iimveliso ze-sar-2 zinzima, eziphakathi kwaye zithambile, ezinoluhlu olubanzi lwezicelo.Ingasetyenziswa ngokubanzi kwiglasi, iplastiki, isinyithi kunye nezinye izinto, ngakumbi ukukhusela iiplastiki ezicacileyo ezifana ne-polycarbonate, i-polystyrene kunye ne-PVC, kunye nobungqina bokufuma kunye nokukhusela ukugquma kwezinto zombane, eziya kuthi kungekudala zenze i-big- imveliso yesikali.

Ukususela kwi-1980 ukuya kwi-1982, i-Qi hongqiu, i-Li Yan kunye ne-Cui Zuoming esuka kwi-Chenguang Chemical Research Institute, kunye ne-1981 ukuya kwi-1983, u-Xu Zhihong no-Xue Zhiqing be-Shanghai resin factory basebenzisa i-methyltrichlorosilane njengeyona nto iphambili yokulungiselela i-silicone yokumelana ne-mica adhesive.Amabakala emveliso yi-mr-30 kunye ne-sar-8 ngokulandelelanayo.Ukongeza kwiqondo eliphezulu lokumelana nobushushu, ukugqunywa kombane, ubungqina bomswakama, ubungqina bamanzi kunye nezinye iipropathi zeemveliso ze-organosilicon ngokubanzi, iimveliso nazo zineempawu eziphezulu zokubambelela kunye ne-flame retardant.Isetyenziselwa ikakhulu ukwenza ubushushu obuphezulu obuxhathisa umgubo webhodi yelifu, ukugqunywa kwetyhubhu ye-elektroniki, ubushushu obuphezulu obunganyangekiyo ngumgubo webhodi yelifu lokuxhasa, ibhodi yemica yokuguqula ubushushu bangaphakathi bomatshini wokuwelda wombane, njl njl. njengezinto zokugquma ezingenamsi kunye nezichasayo ukubola, kwaye zingasetyenziswa njengezinto ezibumba izinto ezingatshayo okanye iresin yokubumba i-ceramic eyenziwe ngeglasi yefiber composite laminate kunye nesilica.I-China ityebile kwimithombo yomgubo we-mica, enokuthi iphuhliswe ibe luluhlu lweemveliso zebhodi ye-mica ezichasene nobushushu obuphezulu.

I-Jiangxi Huahao igxile kwimveliso ye-dimethyldiethoxysilane

I-Sar-8 kunye ne-sar-9 yomzi-mveliso we-resin waseShanghai bathatha eyabo indlela yenkqubo yeempawu: i-hydrolyze kunye ne-alcoholic organosilicon monomers kunye nokugxila kunye ne-polycondensate ngaxeshanye.I-Sar-8 kunye ne-sar-9 zafakwa kwimveliso ngo-1983, kwaye imveliso ifikelele kwiitoni eziphantse zibe liwaka.Eyona nto iphambili yemveliso ye-methyltrichlorosilane, ngoko ke ukuba i-mr-30 okanye i-sar-8 okanye i-sar-9 iveliswa, ixabiso lokusetyenziswa kwe-methyltrichlorosilane linokuphuculwa kakhulu.

Iiplastiki zokubumba ze-Organosilicon

Ngoo-1960, ishishini lenqwelomoya laseTshayina lalifuna ngokungxamisekileyo uhlobo lweplastiki yokungunda ye-arc ekwaziyo ukumelana namandla angoku kunye nombane ophakamileyo wokwenza iiswitshi ezincinci.I-Beijing Research Institute yoshishino lweekhemikhali iphuhlise ngempumelelo i-silicone resin ethi ifakwe ngqo kwi-hydrolyzed ukusuka kwi-methyltrichlorosilane kwaye yenziwe kwi-arc resistant mold plastic ene-asbestos filler, esombulule imfuno engxamisekileyo yoshishino lwenqwelomoya.Izinto eziphathekayo zatshintshelwa kwimveliso ye-resin yaseShanghai ukuze ivelise.Nangona kunjalo, abasebenzisi basalufuna olu hlobo lwezinto, ngoko kufuneka bacele uncedo kwi-Chenguang Chemical Research Institute, eyafudukela kwiPhondo laseSichuan.Ukuze kuhlangatyezwane neemfuno ezingxamisekileyo zabasebenzisi, uWu Shengquan et al.I-Institute isebenzise indlela ye-hydrolysis ye-condensation esuka kwi-methyltriethoxysilane njengento yokuqala ukulungiselela i-silicone resin yokubumba iiplastiki ngokusebenza okwanelisayo, ukuze kulungiswe iimfuno ezingxamisekileyo zabasebenzisi.

Izinto zokutywina ze-silicone resin

Ngasekupheleni kweminyaka yoo-1960, ngophuhliso lweshishini le-elektroniki laseTshayina, kuyimfuneko ukusebenzisa izixhobo zokutywina ze-silicone ezinokufakelwa kombane okugqwesileyo, ukumelana nobushushu obuphezulu, ubungqina bokufuma kunye nokungatshisi ukupakisha iidiode ezinkulu nezincinci zamandla, ii-triodes, resistors, capacitors, iisekethe ezidibeneyo kunye nezinye izixhobo zombane.E-China, uZhang Xinghua, yena Jigang, et al.KwiZiko leKhemistri ye-Academy yaseTshayina yeSayensi, kunye noZhang Jikai, uLi Yansheng, et al.Umzi-mveliso we-resin waseShanghai wabandakanyeka kwangethuba kuphuhliso lwezo ntlaka.Baphuhlise iimveliso ezahlukeneyo zokuvala isithuba sasekhaya.

I-Silicone resin iguquguqukayo yokugqoka

I-silicone ngokubanzi ininzi yenziwe nge-polymethylsiloxane kunye ne-polyphenylsiloxane.Ukuhambelana kwe-silicone resin equkethe i-phenyl kunye ne-organic resin ingcono kune-methyl silicone resin.Ukumelana nokushisa kunye nokuchasana kwamanzi kwiingubo eziqhelekileyo kunokuphuculwa ngokuzisa i-phenyl silicone kubo.Kwishishini lokugubungela, i-siloxane ephezulu equkethe i-coating inokulungiswa ngokuxuba okanye i-copolymerization ye-phenyl equkethe i-silicone resin.Kwangeminyaka yoo-1960s, umzi-mveliso wepeyinti waseTianjin kunye nomzi-mveliso we-resin waseShanghai waphuhlisa ngempumelelo i-silicone eguqulweyo yeresin eyenziweyo.Iintlobo ngeentlobo zeempawu ezilungileyo ziye zaphuhliswa, ezifana ne-silicone ehlaziyiweyo ye-epoxy resin enokumelana nokushisa okulungileyo kunye nokubambelela.
