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 PROCESS FOR THE PRODUCTION OF THE FILM MEMBRANE
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.本發明係關於一種膜,其具有優良的耐候性和高度熱日照透過性且對由地面發出的熱輻射為有效的屏障及具有高機械強度,亦關於此膜之製法。藉由熱塑塑料底膜和聚(甲基)丙烯酸酯外層之複合物獲得此性質。藉具有極性的共聚物獲得黏著性。一或多層之此塑料模製物亦可摻有阻燃劑。
