  • Patent number: 10872989
    Abstract: An encapsulant material for a photovoltaic module. The encapsulant material includes: between 30 and 50 parts by weight of fiber cloth and between 50 and 70 parts by weight of acrylic powder coating. The fiber cloth is made of fiber material. The acrylic powder coating includes an acrylic resin, a curing agent, and an additive. The acrylic powder coating is uniformly coated on the fiber cloth. A method of preparing the encapsulant material includes: uniformly coating the acrylic powder coating on the fiber cloth, thermally bonding the acrylic powder coating and the fiber cloth using pressure and heat, and piecewise cutting the thermally bonded acrylic powder coating and the fiber cloth.

  • Publication number: 20190097071
    Abstract: An encapsulant material for a photovoltaic module. The encapsulant material includes: between 30 and 50 parts by weight of fiber cloth, and between 50 and 70 parts by weight of a polyester powder coating. The polyester powder coating includes a polyester resin and a curing agent. The polyester resin is a polymer of monomers selected from terephthalic acid, m-phthalic acid, neopentyl glycol, adipic acid, ethylene glycol, or a mixture thereof. The curing agent accounts for 2-20 wt. % of the polyester powder coating. The polyester powder coating is evenly distributed on the fiber cloth. A method of preparing the packaging material includes: evenly distributing the polyester powder coating on the fiber cloth using a coating device; and thermally bonding the polyester powder coating and the fiber cloth.
