Dimethyldiethoxysilane ua tus yuam sij rau kev tsim cov khoom siv silicone

Silicone iav resin thiab kub resistant silicone mica nplaum.

Huo Changshun thiab Chen Rufeng los ntawm Chenguang Chemical Research Institute, Ministry of chemical kev lag luam, thiab lwm yam yog tsim silicone iav resin thiab kub mica nplaum nyob rau hauv Suav teb.Thaum xyoo 1970s, cts-103 silicone resin, feem ntau hu ua "silicone iav resin", tau ua tiav tiav los ntawm hydropolycondensation ntawm methyltriethoxysilane nyob rau hauv lub xub ntiag ntawm acid catalyst.Cov resin tau siv rau hauv kev kho cov ntawv qib siab, txheej tiv thaiv ntawm cov hlau nto, thiab kev sib txuas ntawm cov ntawv mica los yog mica hmoov nyob rau hauv thaum ntxov.Xyoo 1980, Sanhua, Xue Zhiqing thiab Li Yansheng, cov chaw tsim khoom lag luam hauv Shanghai, feem, siv cov khoom cation txauv resin ua cov kua qaub ib ntus.Cov pob tshab thiab hnav-resistant silicone resins ntawm sar-1 thiab sar-2 tau tsim los ntawm kev ntxiv me me ntawm dimethyldiethoxysilane rau hauv lub ntsiab monomethyltriethoxysilane.Tsis muaj residual inorganic acid nyob rau hauv cov resin, yog li kev cia khoom ntawm cov khoom yog ruaj khov, thiab tsis muaj cementation yog pom ib xyoos tom qab.Vim qhov kev taw qhia me me ntawm cov khoom siv tsis zoo, sar-2 cov khoom yog tawv, nruab nrab thiab muag muag, nrog rau ntau yam kev siv.Nws tuaj yeem siv dav hauv iav, yas, hlau thiab lwm yam ntaub ntawv, tshwj xeeb tshaj yog rau kev tiv thaiv cov yas pob tshab xws li polycarbonate, polystyrene thiab PVC, thiab rau cov dej-pov thawj thiab rwb thaiv tsev tiv thaiv txheej ntawm cov khoom siv hluav taws xob, uas yuav sai sai no loj- scale ntau lawm.

Los ntawm 1980 txog 1982, Qi hongqiu, Li Yan thiab Cui Zuoming los ntawm Chenguang Chemical Research Institute, thiab los ntawm 1981 txog 1983, Xu Zhihong thiab Xue Zhiqing los ntawm Shanghai resin Hoobkas siv methyltrichlorosilane ua cov ntaub ntawv tseem ceeb los npaj silicone kub resistant mica adhesive.Cov khoom qib yog mr-30 thiab sar-8 feem.Ntxiv nrog rau qhov kub thiab txias tsis kam, hluav taws xob rwb thaiv tsev, noo noo-pov thawj, dej-pov thawj thiab lwm yam khoom ntawm cov khoom siv organosilicon, cov khoom kuj tseem muaj qhov adhesion thiab nplaim retardant zog.Nws yog tsuas yog siv rau kev tsim cov kub resistant hmoov huab motherboard, hluav taws xob raj rwb thaiv tsev, siab kub resistant hmoov cloud motherboard rau kev them nyiaj yug, mica board rau tig sab hauv rwb thaiv tsev ntawm hluav taws xob vuam tshuab, thiab lwm yam. Ntau yam kub-resistant pigments kuj yuav ntxiv. Raws li cov pa luam yeeb dawb thiab tiv thaiv corrosion, thiab tseem tuaj yeem siv los ua incombustible molding composite lossis ceramic molding resin muaj li ntawm iav fiber ntau laminate thiab silica.Tuam Tshoj yog nplua nuj nyob rau hauv mica hmoov cov chaw muab kev pab, uas yuav tsum tau tsim rau hauv ib tug series ntawm kub resistant insulating mica board khoom.

Jiangxi Huahao tshwj xeeb hauv kev tsim cov dimethyldiethoxysilane

Sar-8 thiab sar-9 ntawm Shanghai resin Hoobkas txais lawv tus kheej cov yam ntxwv txoj kev: hydrolyze thiab alcoholysis organosilicon monomers thiab mloog zoo thiab polycondensate tib lub sij hawm.Sar-8 thiab sar-9 tau muab tso rau hauv kev tsim khoom hauv xyoo 1983, thiab cov zis tau mus txog ze li ib txhiab tons.Cov khoom siv tseem ceeb ntawm cov khoom yog methyltrichlorosilane, yog li txawm tias mr-30 lossis sar-8 lossis sar-9 yog tsim los, kev siv tus nqi ntawm methyltrichlorosilane tuaj yeem txhim kho tau zoo.

Organosilicon molding plastics

Nyob rau xyoo 1960, Tuam Tshoj txoj kev lag luam aviation xav tau ib hom arc resistant silicone pwm yas uas muaj peev xwm tiv taus tam sim no thiab high voltage rau kev hloov micro hloov.Beijing tshawb fawb lub koom haum ntawm kev lag luam tshuaj tau ntse tsim silicone resin uas yog ncaj qha hydrolyzed los ntawm methyltrichlorosilane thiab ua rau arc resistant pwm yas nrog asbestos muab tub lim, uas tau daws qhov kev xav tau ceev ntawm aviation kev lag luam.Cov khoom raug xa mus rau Shanghai resin Hoobkas rau ntau lawm.Txawm li cas los xij, cov neeg siv tseem xav tau cov khoom siv no, yog li lawv yuav tsum thov kev pab los ntawm Chenguang Chemical Research Institute, uas tau tsiv mus rau Sichuan Province.Txhawm rau ua kom tau raws li qhov xav tau ceev ntawm cov neeg siv, Wu Shengquan li al.Ntawm lub koom haum siv txoj kev hydrolysis condensation los ntawm methyltriethoxysilane ua cov khoom pib los npaj cov silicone resin rau molding plastics nrog kev ua tau zoo txaus, txhawm rau daws cov kev xav tau ceev ntawm cov neeg siv.

Silicone resin sealing khoom

Nyob rau xyoo 1960, nrog rau kev txhim kho ntawm Tuam Tshoj txoj kev lag luam hluav taws xob, nws yog ib qho tsim nyog yuav tsum siv cov khoom siv silicone sealing nrog cov khoom siv hluav taws xob zoo, kub tsis kam, tsis muaj dej tsis zoo thiab tsis muaj hluav taws xob rau pob loj thiab me zog diodes, triodes, resistors, capacitors, integrated circuits thiab lwm yam khoom siv hluav taws xob.Nyob rau hauv Suav teb, Zhang Xinghua, nws Jigang, thiab al.Ntawm lub koom haum ntawm chemistry ntawm Suav Academy ntawm Sciences, thiab Zhang Jikai, Li Yansheng, thiab al.Ntawm Shanghai resin Hoobkas tau pib thaum ntxov nyob rau hauv txoj kev loj hlob ntawm xws li resins.Lawv tsim ntau yam khoom siv los ua kom muaj qhov sib txawv hauv tsev.

Silicone resin hloov kho txheej

Cov silicone feem ntau yog tsim los ntawm polymethylsiloxane thiab polyphenylsiloxane.Lub compatibility ntawm silicone resin muaj phenyl thiab organic resin yog zoo dua li ntawm methyl silicone resin.Qhov ntsuas kub thiab dej tsis kam ntawm cov txheej txheem dav dav tuaj yeem txhim kho los ntawm kev qhia phenyl silicone rau hauv lawv.Hauv kev lag luam txheej, kev ua haujlwm siab siloxane muaj cov txheej txheem tuaj yeem npaj los ntawm kev sib xyaw lossis copolymerization ntawm phenyl uas muaj silicone resin.Raws li thaum ntxov xyoo 1960, Tianjin xim Hoobkas thiab Shanghai resin Hoobkas ntse tsim cov txheej txheem ntawm silicone hloov hluavtaws cob.Ntau yam khoom zoo tau tsim, xws li silicone hloov kho epoxy resin nrog cov cua sov zoo thiab adhesion.
