Process for Production of Laminated Glass Interleaved with Plastic Film and Laminated Glass Interleaved with Plastic Film
First Claim
1. A production process of a plastic film-inserted laminated glass, the plastic film-inserted laminated glass having a laminated film in which a plastic film of 30 to 200 □
- m in thickness is sandwiched between two resin intermediate films and two glass plates, the process comprising at least the following three steps;
a step 1 for forming a laminate in which the glass plate, the resin intermediate film, the plastic film, the resin intermediate film and the glass plate are laminated together in order of mention;
a step 2 for degassing the formed laminate; and
a step 3 for bonding the degassed laminate by pressing and heating,wherein the steps 1 and 2 are performed under conditions that the temperature of working atmosphere and the temperatures of the plastic film and resin intermediate films fall within a range of 10 to 25°
