FIELD: chemistry.SUBSTANCE: invention relates to sealing material for solar panels and a solar panel module obtained using said sealing material. Sealing material contains at least an adhesive layer (I) and layer (II) of a resin composition (C), which contains a random copolymer of ethylene-α-olefin (A) with crystal melting heat from 0 to 70 J/g, measured at heating rate of 10 °C/min by differential scanning calorimetry (DSC), and a block-copolymer of ethylene-α-olefin (B), which is measured at heating rate of 10 °C/min by DSC maximum crystal melting temperature 100 °C or higher and crystal melting heat from 5 to 70 J/g. Adhesive layer (I) is made from a resin composition (Z), which has crystal melting heat from 0 to 70 J/g, measured at heating rate of 10 °C/min by DSC and contains resin based on polyethylene (X) and resin based on silane-modified ethylene (Y).EFFECT: sealing material meets high requirements for adhesiveness, long-term stability of adhesion strength, transparency and heat resistance, and also facilitates production of solar panel modules.15 cl, 1 dwg, 3 tbl, 12 ex |
