Abstract

The invention provides a chemical heat insulation composite film and a preparation process thereof, the composite film comprises: a polyester film layer comprising a first polyester film layer and a second polyester film layer, the density of the first polyester film layer being greater than the density of the second polyester film layer; the fluorine-silicon nano coating is coated on the second polyester film layer; the first polyester film layer, the second polyester film layer and the fluorosilicone nano coating are sequentially arranged to form the composite film. The composite film and the preparation process thereof have the advantages of being simple in structure, low in production cost, high in efficiency and good in heat insulation and heat preservation performance, mechanical strength, damp-heat aging resistance and corrosion resistance.

Description

technical field [0001] The invention relates to a composite film, in particular to a chemical heat insulation composite film and a preparation process thereof. Background technique [0002] With the development of polymer material technology, more and more composite membranes have been widely used in production and life. At present, there are many different types of composite films on the market, such as barrier composite films, heat-resistant composite films, selectively permeable composite films, fresh-keeping composite films, conductive composite films, etc. for different use scenarios. [0003] Among a wide variety of composite films, thermal insulation composite films are widely used, which requires composite films to have good thermal insulation performance, mechanical strength and moisture-heat aging resistance. When the thermal insulation composite membrane is used in the chemical industry, it is also required to have good corrosion resistance. [0004] Usually, th...
