  • Publication number: 20220145072
    Abstract: The present disclosure discloses a photosensitive resin composition and a use the same. The resin composition of the present disclosure includes 40-70 parts by weight of an alkali-soluble resin, 20-50 parts by weight of a photopolymerizable monomer, 0.5-10.0 parts by weight of a photoinitiator, and 0.1-10.0 parts by weight of additives. The photopolymerizable monomer includes 0.5-15.0 parts by weight of a monomer containing carbonate structure. The photosensitive resin composition is used as a dry film resist. It has characteristics such as easy breakage of film strip, smaller film strip fragments, faster film strip speed, excellent flexibility, and good circuit resolution and adhesion, thereby effectively improving production efficiency and product yield.

  • Publication number: 20200347211
    Abstract: The present disclosure discloses a low-water-vapor-permeability polyolefin-elastomer film and its preparation method. The film comprises: 50-100 mass parts of a matrix resin, 0-40 mass parts of a modified resin, 0.001-2 mass parts of an activator, 0.1-3 mass parts of an organic peroxide, 0.02-5 mass parts of an assistant cross-linker, 0.02-2 mass parts of a silane coupling agent, 0.005-2 mass parts of a light stabilizer, and 0-20 mass parts of a water blocking filler. In the present disclosure, by adding the modified resin and the activator that have an active group, a cross-linking degree and a cross-linking density of the film are improved, and a water-vapor permeability is reduced; by adding the water blocking filler, the water blocking property of the film is further improved, thereby ensuring reliability of the assembly, and prolonging service life of the assembly.

  • Publication number: 20200028011
    Abstract: A highly reflective gain type photovoltaic packaging adhesive film and usage are provided. The packaging adhesive film is composed of an packaging layer and a reflecting layer, wherein the packaging layer has a thickness of 200 to 500 ?m, and is made by mixing a first primary resin, a modified auxiliary, an ultraviolet auxiliary, an anti-thermal oxidation ageing agent and an initiator and melting and coat casting the same at 60° C. to 200° C. to form a film; and the reflecting layer has a thickness of 5 to 200 ?m and is made by mixing a second primary resin, an auxiliary resin, a first filler, a second filler, modified auxiliary, a diluent and an ultraviolet auxiliary, an anti-thermal oxidation ageing agent and an initiator and coating the same on the surface of the packaging layer and curing the same at 30° C. to 150° C.
