Embodiment 1

[0036] Using the layered structure of the reinforced heat-insulating composite film with wire grid intervals of the present invention and the materials and processing technology in the following table, and using the heat-insulating composite film prepared by the present invention, place it under the high temperature condition of 200°C, The actually measured steady-state temperature on the inner surface of the composite membrane is shown in column Example 1 of the table below. Actual visual inspection revealed that the surface was intact. This proves that the composite membrane has excellent high temperature resistance.

Embodiment 2

[0038] Using the layered structure of the reinforced heat-insulating composite film with wire grid intervals of the present invention and the materials and processing technology in the following table, and using the heat-insulating composite film prepared by the present invention, place it under the high temperature condition of 240°C, The actually measured steady-state temperature on the inner surface of the composite membrane is shown in column 2 of Example 2 in the table below. Actual visual inspection revealed that the surface was intact. This proves that the composite membrane has excellent high temperature resistance.

Embodiment 3

[0040] Adopt the hierarchical structure of the reinforced heat-insulation composite film with wire grid intervals of the present invention and the materials and processing technology in the following table, and adopt the heat-insulation composite film prepared by the present invention, and place it under the low temperature condition of -220°C , The actual measured composite membrane inner surface steady-state temperature is shown in the column of Example 3 in the table below. Actual visual inspection revealed that the surface was intact. This proves that the composite membrane has excellent low temperature resistance.

Abstract

The invention relates to an enhanced heat-insulation composite film spaced by a metal wire grating and application thereof. The enhanced heat-insulation composite film consists of 3-20 layers of sandwich metal-plated high-polymer composite films which are spaced by parallel or orthorhombic metal wire gratings on fiber meshes. The enhanced heat-insulation composite film is characterized in that one side of the enhanced heat-insulation composite film can bear the effect of high temperature and low temperature within negative 250DEG C to 250DEG C, the other side of the enhanced heat-insulation composite film is kept to be at 5-40DEG C normal temperature, the enhanced heat-insulation composite film is a multilayer composite material which can realize rapid and even heat distribution, heat insulation and warmth keeping, the natural thickness is 4-20mm, the actual compact thickness is 1-8mm, the weight per square meter is 40-800g/m<2>, and the enhanced heat-insulation composite film is a fully-closed bonded or sewn heat-insulation, warmth-keeping soft enhanced heat-insulation composite film. The enhanced heat-insulation composite film can be solely used or can be combined with other materials and be used for human body protection and environmental heat insulation of high-temperature and low-temperature occasions such as firefighting, military, exploration and industry.

Description

technical field [0001] The invention relates to the light and thin flexible composite film material technology for heat insulation and protection of the human body or the environment, and in particular to a reinforced heat insulation composite film separated by wire grids. Human body protection and environmental heat insulation in special occasions such as industry. Background technique [0002] Human body protection under the condition of temperature field is the most basic content in the research of protective materials. Most of the research and patents of high-performance flexible protective materials also start from the general high or low temperature environment (the temperature is -250 ℃ ~ 250 ℃, such as in space Cold and radiant heat environment, cold or hot environment in activities such as polar or volcanic expeditions, high or low temperature environment in industrial processing workshops) special occasions. [0003] Due to the good flexibility, light weight and s...
