PROTECTIVE SHEET FOR REAR SURFACE OF SOLAR CELL |
摘要 |
This invention provides a solar cell rear surface protection sheet comprising two or more substrates laminated together by means of an adhesive, the adhesive comprising a urethane resin obtained by mixing an acrylic polyol, an isocyanate compound, 3-glycidoxypropyltriethoxysilane, and tin octylate, wherein
the acrylic polyol being obtained by polymerizing polymerizable monomers, the polymerizable monomers comprising a hydroxyl group-containing monomer and other monomers, the other monomers comprising acrylonitrile,the isocyanate compound comprising both a xylylene diisocyanate monomer and hexamethylene diisocyanate isocyanurate, the xylylene diisocyanate monomer being is present in an amount of 20 to 40 wt %, and the hexamethylene diisocyanate isocyanurate is present in an amount of 80 to 60 wt % andthe equivalent ratio of isocyanate groups of the xylylene diisocyanate monomer and the hexamethylene diisocyanate isocyanurate to hydroxyl groups of the acrylic polyol being 1.0 to 3.0. |

1. A solar cell rear surface protection sheet comprising two or more substrates laminated together by means of an adhesive, the adhesive comprising a urethane resin obtained by mixing an acrylic polyol, an isocyanate compound, 3-glycidoxypropyltriethoxysilane, and tin octylate;
(1) the acrylic polyol being an acrylic polyol obtained by polymerizing polymerizable monomers, the polymerizable monomers comprising a hydroxyl group-containing monomer and other monomers, the other monomers comprising acrylonitrile, the acrylonitrile being present in an amount of 5.0 to 15.0 wt % based on the total weight (100 wt %) of the polymerizable monomers; (2) the isocyanate compound comprising both a xylylene diisocyanate monomer and hexamethylene diisocyanate isocyanurate, wherein, based on the total weight (100 wt %) of the xylylene diisocyanate monomer and the hexamethylene diisocyanate isocyanurate, the xylylene diisocyanate monomer is present in an amount of 20 to 40 wt %, and the hexamethylene diisocyanate isocyanurate is present in an amount of 80 to 60 wt %; (3) the equivalent ratio of isocyanate groups of the xylylene diisocyanate monomer and the hexamethylene diisocyanate isocyanurate to hydroxyl groups of the acrylic polyol being 1.0 to 3.0. |
