A. izinto ombane Low yokugquma
1.1 Ifomula
Intsimbi ye-Epoxy E-44 100
Umtsalane weDibromophenyl glycidyl ether 20
Flame nekudodobalisa antio-trioxide 10
I-silica powder esebenzayo i-400 mesh 200
Iarhente yokuphilisa 593 25
Uhlobo lweDetylenetriamine 3
1.2 Inkqubo yokuvelisa
1.2.1 Umgubo wesilicon owomileyo kumxholo wokufuma okungaphantsi kwe-0.2%
1.2.2 Yongeza i-epoxy resin, i-thinner, i-flame retardant, kunye ne-silicon powder kwi-reactor kule ndlela elandelayo
1.2.3 Nyusa iqondo lobushushu ukuya kwi-100 ℃, idigas umxube phantsi kwe -0.1Mpa vacuum ye-30min ukufana
1.2.4 Pholisa ukuya ngaphantsi kwe-50 ° C, yongeza iarhente yokuphilisa, gcina iqondo lobushushu lingabikho ngaphezulu kwe-50 ° C, isidanga se-degas degree -0.1Mpa, ixesha lokuxuba ngaphezulu kwe-30min, emva koko ungene kwinkqubo yokuphosa.
B. Amandla ombane aphezulu kunye nezinto ezisezantsi zokufaka umbane
2.1 Ukuqulunqwa
Intsimbi ye-Epoxy E-44 100
Umtsalane weDibromophenyl glycidyl ether 20
Flame nekudodobalisa antio-trioxide 10
I-silica powder esebenzayo i-400 mesh 300
Iarhente yokuphilisa i-S101 95
Ukukhawulezisa DMP-30 1.5
Inkqubo yokuvelisa
2.2.1 Umgubo wesilicon owomileyo kumxholo wokufuma okungaphantsi kwe-0.2%
2.2.2 Yenza izinto ezibini ngolu hlobo lulandelayo
Icandelo le-epoxy resin, i-accelerator, i-flame retardant, i-silicon powder 200
Icandelo lokuphilisa iarhente, ukubhitya, i-silicon powder 100
I-2.2.3 Icandelo liyashushu ukuya kwi-80-100 ℃, kwaye umxube ususwe ngaphantsi kwe -0.1Mpa nge-30min ukuya kufana
2.2.4 Ubushushu beCandelo B buphakanyisiwe ukuya kwi-50 ℃, kwaye umxube ususwe ngaphantsi kwe -0.1Mpa nge-30min ukufana
2.2.5 Kupholile ukuya ngaphantsi kwe-50 ℃, yongeza icandelo A kwicandelo B, gcina iqondo lobushushu lingadluli kwi-50 ℃, isidanga se-degas -0.1Mpa, ixesha lokuxuba i-30min, ungangena ugalele.
