Film Membrane with Excellent Weather-Resistant Properties, High Transmission of Solar Thermal Radiation, Effective Retention of Thermal Radiation Emitted by the Earth and High Degree of Mechanical Strength and Method for Producing Said Film Membrane

摘要

The invention relates to a film membrane which has excellent weathering resistance and high permeability to thermal insolation, and is an effective barrier to thermal radiation emitted from the ground and has high mechanical strength, and also to a process for the production of the film membrane. The properties are achieved via a composite of a base film of thermoplastic and an outer layer of poly(meth)acrylate. The adhesion is achieved via copolymers with polar character. One or more layers of the plastics moulding may also have been equipped with flame retardants.
