Embodiment approach
[0049] As a preferred embodiment of the present invention, the first modifier contains at least one phenolic hydroxyl group and at least one triazole group.
[0050] In the present invention, specific examples of the first modifier include but are not limited to 3-(3-(benzotriazol-2-yl)-5-tert-butyl-4-hydroxyphenyl)propionic acid methyl Esters, 2-(2'-hydroxy-3',5'-dipentylphenyl)benzotriazole, 2-(2'-hydroxy-5'-methylphenyl)benzotriazole, 5- (Hydroxymethyl)-1H-benzotriazol-1-ol, 2-(2'-hydroxy-3',5'-di-tert-pentylphenyl)benzotriazole, 2-(5-tert-butyl Base-2-hydroxyphenyl)benzotriazole, N-[2-(2-hydroxyphenyl)benzotriazol-5-yl]-2-methylprop-2-enamide, 2-(2 '-Hydroxy-3'-isobutyl-5'-tert-butylphenyl)benzotriazole, 2-(2'-hydroxy-3',5'-di-tert-butylphenyl)-benzotriazole Azole, 2-(2'-hydroxy-3',5'-di-tert-butylphenyl)-5-chlorobenzotriazole, 2'-(2'-hydroxy-3'-tert-butyl-5 '-Methylphenyl)-5-chlorobenzotriazole, 5-hydroxybenzotriazole, 4-(3-hydroxyphenyl)-4H-1,2,4-triazole, 2,4-di Hyd...
Embodiment 1
[0090] Such as figure 1 , a high-stick polyolefin anti-adhesive film, from bottom to top is a barrier layer 1, a substrate layer 2, and a silicone oil layer 3. The silicone oil layer is the rubberized surface. The substrate layer is polyethylene. The silicone oil layer is thermosetting oily silicone oil.
[0091] The barrier layer is obtained by blending PVA and modified acrylic polymer, and the weight ratio of PVA to modified acrylic polymer is 25:1. The raw materials for the preparation of the modified acrylate polymer include, in parts by weight: 100 parts of glycidyl methacrylate, 1.5 parts of 2-(2H-1,2,3-triazol-2-yl)phenol , 3 parts of 5,5'-methylene disalicylic acid, 0.3 parts of peroxydecanoic acid. Its preparation method is 100 parts of glycidyl methacrylate, 1.5 parts of 2-(2H-1,2,3-triazol-2-yl)phenol, 3 parts of 5,5'-methylene disalicylic acid Mix and heat to 165°C, then add 0.3 parts of peroxydecanoic acid, keep stirring for 15 hours, cool, and set the shape ...
Embodiment 2
[0094]A polyolefin anti-adhesive film with high viscosity retention, which consists of a barrier layer, a substrate layer and a silicone oil layer from bottom to top. The silicone oil layer is the rubberized surface. The substrate layer is polypropylene. The silicone oil layer is water-based silicone oil.
[0095] The barrier layer is obtained by blending EVOH and modified acrylic polymer, and the weight ratio of EVOH to modified acrylic polymer is 25:1. The raw materials for the preparation of the modified acrylate polymer include, in parts by weight: 100 parts of glycidyl methacrylate, 1.5 parts of 2-(2H-1,2,3-triazol-2-yl)phenol , 3 parts of 5,5'-methylene disalicylic acid, 0.3 parts of peroxydecanoic acid. Its preparation method is 100 parts of glycidyl methacrylate, 1.5 parts of 2-(2H-1,2,3-triazol-2-yl)phenol, 3 parts of 5,5'-methylene disalicylic acid Mix and heat to 165°C, then add 0.3 parts of peroxydecanoic acid, keep stirring for 15 hours, cool, and set the shap...
