Abstract

The present invention relates to one kind of heat isolating composite film and its preparation process and use. Structurally, the heat isolating composite film consists of compounded base polymer film of high strength and low heat conducting coefficient, metal layer with high reflecting performance, metal oxide layer with high heat isolating performance and outer polymer film with low heat conducting coefficient and high hot adhering strength. The composite film may have thickness of 12-1000 micron. The heat isolating composite film is prepared through evaporation plating one very thin compact metal layer and one very thin loose metal layer successively onto rolled polymer film and then oxidizing, or evaporation plating metal oxide layer directly; and final rolling or curtain coating one other polymer film layer. The heat isolating composite film has excellent heat insulating performance, is light, thin and soft, and may be used in various flexible heat insulating material.

Description

Technical field:

[0001] The invention relates to the field of functional composite materials, and is a high-performance heat-insulating flexible composite membrane material and its preparation and application technology. Background technique:

[0002] Membrane science and technology has developed rapidly since the 1950s, and has been widely used in industry, agriculture, medicine and other fields, and has become a branch of structural and functional materials. As far as the basic problems and applications of membrane science and technology are concerned, it is membrane materials or membrane structure and functional materials. Due to the good flexibility, light weight and strong compoundability of membrane structural materials, rigid materials can be changed into flexible materials, and materials can be used efficiently and in a targeted manner. Therefore, in recent years, new materials and new Technologies and new processes are constantly emerging, and relevant basic and ap...
