Embodiment 1
[0038] Add 1 part of rosin glyceride tackifying resin to 100 parts (by weight, the same below) of natural rubber latex (solid content is 60%), stir evenly and add 1 part of crosslinking agent dicumyl peroxide, 0.5 part of softener Paraffin base oil, 0.5 parts of rubber anti-aging agent N-phenyl-N`-cyclohexyl p-phenylenediamine, after stirring for 5 minutes, add 10 parts of acrylate polymer (solid content is 50%), and then add 0.5 parts of coupling Agent vinyl silane, made into adhesive liquid; such as figure 1 As shown, apply the prepared adhesive solution at a thickness of 30g / m 2 The second surface of the chemical fiber substrate layer 2, that is, the lower surface of the polyester fiber cloth, forms an adhesive layer 3, and its thickness is 10g / m 2 (in terms of solid content); then put it in an oven at 100°C to dry for 5 minutes, take it out and cool it, and coat the release agent polyvinyl alcohol perfluorinated urethane on the first surface of the polyester fiber cloth, ...
Embodiment 2
[0040] Add 2 parts of rosin glyceride tackifying resin to 100 parts of natural rubber latex (solid content: 60%), stir evenly, add 2 parts of crosslinking agent benzoyl peroxide, 1 part of softener naphthenic oil, 1 part of rubber Anti-aging agent N-phenyl-N`-cyclohexyl-p-phenylenediamine, after stirring for 6 minutes, add 20 parts of acrylic polymer (solid content: 50%), and then add 1 part of coupling agent aminosilane to form a gel Adhesive liquid; apply the prepared adhesive liquid to a thickness of 40g / m 2 The lower surface of the glass fiber cloth, the adhesive layer formed, its thickness is 15g / m 2 (in terms of solid content); then put it in an oven at 120°C to dry for 5 minutes, take it out and coat the upper surface of the glass fiber cloth with a release agent containing a perfluorinated alkyl amino resin to form a release agent layer, Its thickness is 15g / m 2 (based on solid content); then put it in an oven at 100°C to dry for 4 minutes, take it out and cool it, c...
Embodiment 3
[0042] Add 5 parts of rosin glyceride tackifying resin to 100 parts of natural rubber latex (solid content is 60%), stir well and add 3 parts of crosslinking agent di-tert-butyl peroxide, 2 parts of softener aromatic base oil, 1.5 parts Rubber anti-aging agent N-phenyl-N`-isopropyl-p-phenylenediamine, after stirring for 7 minutes, add 30 parts of acrylate polymer (solid content is 50%), and then add 2 parts of coupling agent epoxy Silane, made into adhesive liquid; apply the prepared adhesive liquid on the surface with a thickness of 50g / m 2 The lower surface of the polyamide fiber cloth, the adhesive layer formed, its thickness is 17g / m 2 (in terms of solid content); then put it in an oven at 110°C to dry for 7 minutes, take it out and cool it, and coat the upper surface of the polyamide fiber cloth with a release agent dimethyl polysiloxane with silanol as the end group. Formed release agent layer, its thickness is 16g / m 2(based on solid content); then put it in an oven at...
