Abstract

An infrared barrier for high-molecular polymer such as PVC resin paint, oil vanish, emulsoid, polyolefin film, or synthetic fibre is prepared from nm-class or sub-micron-class oxide or carbide particles with higher infrared absorbing and reflecting power through coating. Said infrared barrier may be powder or particles as mother material.

Description

Technical field: [0001] The invention belongs to the technical field of blocking infrared radiation, and particularly relates to nanoparticles (particle size 10--100nm) or / and submicron microparticles (particle size 100nm--15μm) capable of absorbing and reflecting infrared radiation such as oxides or carbides . After the surface coating treatment, the particles can be uniformly dispersed in the high molecular polymer or in the coating material made of the film-forming high molecular polymer as a carrier to form stable functional nano- or / and sub-layers. Microparticle-polymer composite structure. technical background: [0002] As we all know, the molecules and atoms of matter are in constant motion, and their motion states are also constantly changing periodically, and constantly radiating energy outward during the change, which is the phenomenon of thermal radiation of matter. Thermal radiation is mostly manifested by infrared radiation. The intensity and spectral composi...
