Laminated glass with plastic film insert

摘要

In a laminated glass, a plastic film is sandwiched between two sheets of resin intermediate film, and an infrared reflective film is formed in the plastic film by alternatively laminating resin films of different refractive indexes. The plastic film on which the infrared reflective film is formed meets any of the following conditions: (A) thermal shrinkage of 0.5 to 3% in the 90 through 150° C. temperature range, (B) modulus of elasticity in the range of 30 through 2000 MPa in a temperature range of 90 through 150° C., and (C) a rate of elongation of the plastic film of 0.3% or less when 10 N tensile force per 1 m width of the plastic film is exerted in the 90 through 150° C. temperature range. This laminated glass is a curved infrared ray reflective laminated glass, with high transmissivity to visible light, high reflectivity in the infrared ray region, excellent insulating effect, and will transmit various electromagnetic waves.
