Problems solved by technology

However, polyethylene has poor selectivity to far-infrared light transmission, low transmittance of polyethylene to mid-infrared and near-infrared, and poor compatibility with inorganic compound crystals. If polyethylene is simply blended with inorganic crystals, The obtained material has low infrared light transmittance, poor physical properties, and does not have practical value

Abstract

The invention discloses a far infrared ray transmitting composite material and a preparation method thereof. The far infrared ray transmitting composite material comprises the following components in percentage by weight: 50-95% of polyethylene and 5-50% of a modified far infrared ray transmitting agent, wherein the modified far infrared ray transmitting agent takes the far infrared ray transmitting agent as a core and epoxy and a curing agent as a shell. The polyethylene and the modified far infrared ray transmitting agent are compounded and used, so that the far infrared ray transmitting composite material not only has good mechanical strength and is easy to mold, but also has a strong far infrared ray transmitting capacity. The modified far infrared ray transmitting agent is good in compatibility with polyethylene, so that the problem that polyethylene is poor in compatibility with inorganic crystals is solved. The far infrared ray transmitting composite material disclosed by the invention further has excellent electrical insulating property and stability. The polyethylene is low in cost, and the production cost is greatly saved compared with the far infrared ray transmitting agent which is singly used. According to the preparation method, the polyethylene and the modified far infrared ray transmitting agent are mixed, melted and extruded, and the preparation method is simple in process, low in cost and suitable for industrialized production.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a far-infrared-transmitting composite material and a preparation method thereof. Background technique [0002] Infrared detection technology occupies a very important position in the modern national defense high technology. The preparation of various missiles, infrared early warning, observation and aiming are all inseparable from infrared detection technology.
