Abstract
The present invention provides an electrically insulating resin composition comprising a polysulfone resin including a plurality of sulfonyl groups in the molecule and a polyamide resin, wherein the proportion of the polyamide resin is 1 to 45% by mass. The present invention also provides a laminate sheet obtained by bonding a plurality of sheet materials with a resin composition layer interposed therebetween, wherein the resin composition layer comprises a polysulfone resin including a plurality of sulfonyl groups in the molecule and a polyamide resin, and the proportion of the polyamide resin is 1 to 45% by mass.
Claims10
A laminate sheet consisting of one resin composition layer and two sheet layers,
- wherein each of the sheet layers is disposed on opposing surfaces of the resin composition layer and the two sheet layers are bonded to each other with the resin composition layer interposed therebetween,
- wherein the resin composition layer comprising a polysulfone resin including a plurality of sulfonyl groups in a molecule and a polyamide resin, and the proportion of the polyamide resin is 10 to 40% by mass,
- the polysulfone resin is a polyether polyphenylsulfone resin that includes a plurality of ether bonds and a plurality of aromatic hydrocarbons in the molecule,
- the polyamide resin is a semi-aromatic polyamide resin obtained by polymerizing aliphatic diamine with aromatic dicarboxylic acid,
- each of the sheet layers comprises wholly aromatic polyamide,
- the laminate sheet meets a UL94 VTM-0 standard, and
- the laminate sheet exhibits a peel strength of 1.1 N/10 mm or higher and 2.2 N/10 mm or less.
