Embodiment 1

[0038] Using the hierarchical structure of the heat-insulating composite film with fiber web 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, and placing it under the high temperature condition of 220°C, the measured composite The steady-state temperature of the inner surface of the film 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

[0040] Using the layered structure of the heat-insulating composite film with fiber web 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, and placing it under the high temperature condition of 250°C, the measured composite The steady-state temperature of the inner surface of the film is shown in the column 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

[0042] Using the layered structure of the heat-insulating composite film with fiber web 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, it is placed under the low temperature condition of -240°C, and the actual measured The steady-state temperature of the inner surface of the composite membrane 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 a fiber mesh spaced thermal insulation composite film and application thereof. The thermal insulation composite film is configured by laminating of 2-20 layers of metallized polymer composite films, and fiber meshes, doped with or without metal chopped fibers, spaced in the metallized polymer composite films. The thermal insulation composite film is characterized in that it is a multilayer composite thermal insulation material with a warmth retention structure that one side can bear effect of high or low temperature of -250-250 DEG C, and the other side keeps a normal temperature at 5-40 DEG C; the thermal insulation composite film has a thickness of 4-20 mm, an actual compaction thickness of 1-6 mm, and weight per square meter of 40-600g / m<2>, and is a fully closed, adhered or sewed thermal insulation, warmth retention and soft laminating thermal insulation composite film. The thermal insulation composite film can be applied alone or combined with other materials in body protection and environment insulation for high and low temperature occasions, such as fire protection, military, adventure and industry.

Description

technical field [0001] The present invention relates to the light and thin flexible composite membrane material technology for heat insulation and protection of human body or environment temperature, especially relates to a kind of heat insulation composite membrane separated by fiber net, the heat insulation composite membrane can be applicable to fire fighting, military affairs, exploration, industrial etc. Personal protection and environmental heat insulation for special occasions in low temperature occasions. 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...
