Embodiment 1
[0031] The olefin copolymer layer formula is as follows: in parts by mass, 100 parts of VA content is 30% ethylene-vinyl acetate copolymer (U.S. DuPont), add, 0.2 parts of crosslinking agent tert-butyl peroxyisopropyl carbonate Esters (Bailingwei Technology Co., Ltd.), 0.2 parts of antioxidant tris(2,4,-di-tert-butylphenyl) phosphite (Tianda Tianhai Technology Development Co., Ltd.), 0.1 parts of light stabilizer sebacic acid bis- 2,2,6,6-tetramethylpiperidinol ester (Shanghai Yanjia Plastic Chemical Co., Ltd.), and mix well. The mixture was blended and extruded in an extruder, and the temperature was controlled at 90° C. After extrusion, it was cast and cooled to obtain a 50 μm thick olefin copolymer layer.
[0032] The weather-resistant layer formula is as follows: in parts by mass, 100 parts of polyurethane resin 611-B (Taiwan Changxing), 20 parts of modified resin ST5790 (Japan Toyobo), 15 parts of curing agent N3390 (German Bayer) , 1 part of curing agent accelerator dib...
Embodiment 2
[0036] The formulation of the olefin copolymer bonding layer is as follows: in parts by mass, in 100 parts of ethylene-pentene-zincene copolymer (Exxon Mobil, USA), add 2 parts of vinyltrimethoxysilane (Bailingwei Technology Co., Ltd.), 1.2 Part of antioxidant 2,2'-methylene-bis-(4-ethyl-6-tert-butylphenol) (Shanghai Ruiding Chemical Company), 0.01 part of hindered amine light stabilizer bis-1-decane Oxy-2,2,6,6-tetramethylpiperidin-4-ol sebacate and mix well. The mixture was blended and extruded in an extruder, and the temperature was controlled at 90° C. After extrusion, it was cast, cooled, cut, and rolled to obtain a 5 μm thick inner film layer.
[0037] The formula of the weather-resistant layer is as follows: in parts by mass, 100 parts of fluorine-containing resin GK570 (Dakin Paint of Japan), 10 parts of curing agent z4470 (Bayer, Germany), 0.5 parts of curing agent accelerator dilauric acid dilaurate Butyl tin and 10 parts of solvent propylene glycol methyl ether ace...
Embodiment 3
[0041] The formula of the olefin copolymer bonding layer is as follows: in parts by mass, in 100 parts of ethylene-propylene copolymer (U.S. DuPont), add 5 parts of crosslinking agent 1-bis(tert-butyl peroxide)-3,3, 5-trimethylcyclohexane (Bailingwei Technology Co., Ltd.), 3 parts of antioxidant 2,2'-methylene-bis-(4-ethyl-6-tert-butylphenol) (Shanghai Ruiding Chemical Company ), 2 parts of hindered amine light stabilizer 3,5-di-tert-butyl-4-hydroxyl-benzoic acid hexadecyl ester and mix well. The mixture was blended and extruded in an extruder, and the temperature was controlled at 120°C. After extrusion, it was flow-cast and cooled to obtain an inner film layer with a thickness of 100 μm.
[0042] The formula of the weather-resistant layer is as follows: in parts by mass, in 100 parts of fluorine-containing resin GK570 (Dakin paint in Japan), add 100 parts of unsaturated polyester resin ST5790 (Toyobo in Japan), 30 parts of curing agent z4470 (Germany Bayer), 2 parts of curi...
