Abstract
A method for producing a laminate (E) of a low air permeable resin/rubber composition comprising: laminating a laminate (D) of a low air permeable resin (A) layer having an air permeation coefficient of 1.0×10−12 cc·cm/cm2·sec·cmHg or less and an average thickness d (μm) of 0.05<d<5 and a thermoplastic resin composition (B) layer with a rubber composition (E) layer so as to form (B)/(A)/(E), followed by vulcanization, and peeling off only the thermoplastic resin composition (B) from the laminate, as well as the laminate thereof.
Claims20
A laminate (F) of a low air permeable resin/rubber composition comprising a low air permeable resin (A) layer having an air permeation coefficient of 1.0×10−12 cc·cm/cm2·sec·cmHg or less and an average thickness d (μm) of 0.05<d<5, laminated to at one surface of a rubber composition (E) layer.
A method for producing a laminate (F) of a low air permeable resin/rubber composition comprising a rubber composition (E) layer laminated, at one surface thereof, with a low air permeable resin (A) layer comprising:
- laminating a laminate (D) of a low air permeable resin (A) layer having an air permeation coefficient of 1.0×10−12 cc·cm/cm2·sec·cmHg or less and an average thickness d (μm) of 0.05<d<5 and a thermoplastic resin composition (B) layer in a quasi-bonded state with the (A) layer and having a peeling strength from the (A) layer at room temperature of 0.001 to 10N/mm with a rubber composition (E) layer to so as to form a laminate of (B)/(A)/(E), followed by vulcanization, such that the peeling strength between the low permeability resin (A) layer/the rubber composition (E) layer after the vulcanization is larger than the peeling strength between the (A) layer/the (B) layer;
- and
- peeling off only the thermoplastic resin composition (B) from the laminate.
A method for producing a laminate (F) of a low air permeable resin/rubber composition comprising a rubber composition (E) layer laminated, at one surface thereof, with a low air permeable resin (A) layer comprising:
- laminating a three-layer laminate (D) comprised of a low air permeability resin (A) layer having an air permeation coefficient of 1.0×10−12 cc·cm/cm2·sec·cmHg or less and an average thickness d (μm) of 0.05<d<5, a thermoplastic resin composition (B) layer in a quasi-bonded state with the (A) layer and having a peeling strength from the (A) layer at room temperature of 0.001 to 10N/mm, and an adhesive (C) laminated in the order of (B)/(A)/(C) with a rubber composition (E) layer so as to form a laminate of (B)/(A)/(C)/(E), followed by vulcanization such that the peeling strength between the low permeability resin (A) layer/the rubber composition (E) layer after the vulcanization is larger than the peeling strength between the (A) layer/(B) layer, and;
- peeling off only the thermoplastic resin composition (B) from the laminate.
