COATING AGENT FOR FORMING ELECTROCORROSION PREVENTION LAYER, AND THERMAL SHIELDING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a thermal shielding material with a thermal shielding layer in which electrocorrosion prevention effect and thermal shielding effect are made consistent.SOLUTION: An electrocorrosion prevention layer 2 made of polyvinyl chloride (PVC) with a thickness of 10 microns or lower on an aluminum layer 1 as aluminum alloy foil as the stock with a high reflection rate to radiation heat with a coating film to form into a thermal shielding material in which the reduction of reflectivity to the radiation heat of the aluminum layer 1 can be controlled to 10% or lower, particularly, 1% or lower, and satisfactory electrocorrosion effect having performance that corrosion is not caused after the passage for 20 years after its installing at the inside of a room can be recognized.SELECTED DRAWING: Figure 1
