Abstract

The invention discloses a compound material which comprises a fiber liner substrate layer, wherein the upper surface of the fiber liner substrate layer is covered with a polymer foaming layer and a compound warm-keeping layer from lower to upper; the compound warm-keeping layer is of a sandwich structure; and the nanometer grains having an infrared radiation function are arranged in the sandwich structure. The laminated compound material has excellent functions of preventing oil and chemical pollution, degeneration, and the like, and is suitable for the chemical protection in the multiple labour transportation fields.

Description

1. Technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a layered composite material specially used for labor and transportation protection. 2. Background technology [0002] In the process of transportation, impact damage to the transported items often occurs. In addition, for some items that have high requirements for the storage environment, the sudden change in the external environment of the item due to transportation will also affect some items. Items are adversely affected. Therefore, many items need to be provided with special protective materials outside during transportation, so as to avoid possible adverse effects during transportation. [0003] In addition to the protection of items during transportation, the human body often needs safety protection during labor. Currently commonly used labor protection products include safety helmets, seat belts, gloves, safety shoes, protective shoes, etc. Th...
