Abstract

La présente invention concerne un revêtement isolant thermique capable de réfléchir les rayons de la chaleur du soleil, qui est composé d'une couche inférieure et d'une couche superficielle. Les pourcentages de matériaux solides dans la couche inférieure sont de 5 à 40 % de matériaux thermo-isolants sous la forme de microsphères creuses, de 10 à 50 % de matériaux réfléchissant la chaleur, et de 10 à 70 % de résine de liaison polymère. Les pourcentages de matériaux solides dans la couche superficielle sont de 5 à 40 % de matériaux de composés enrobés pour réfléchir les rayons thermiques, de 10 à 50 % de matériaux réfléchissant la chaleur, et de 10 à 70 % de résine de liaison polymère. Le revêtement est principalement utilisé en tant que la couche superficielle de bâtiments, voitures, trains, pipelines, et cuves. Lorsque l'épaisseur de la couche humide est de 0,3 à 0,5 mm, la réflectivité totale des rayons thermiques réfléchis peut atteindre 85 à 90 %, et peut ainsi efficacement empêcher l'irradiation des rayons thermiques du soleil.
