Problems solved by technology

[0002] Generally, tents and sunshade nets used outdoors do not have the function of infrared reflection. Although the naked eye can see the color very similar to the natural world, the target is undoubtedly exposed under the infrared imager of the military high-altitude helicopter. Or rarely have the ability to reflect infrared light, people work under such a sunshade net, because the sunshade net absorbs most of the sun's heat, it seems very stuffy

Abstract

The invention provides a polyolefin color masterbatch having an infrared reflection effect. The polyolefin color masterbatch comprises, by weight, 40 to 85% of a carrier resin, 5 to 35% of an infrared reflection pigment, 0 to 15% of color blending pigments, 2 to 15% of a dispersant and 5 to 10% of an anti-aging agent. The color masterbatch has the function of infrared camouflage and the effect oflowering down temperature.

Description

Technical field [0001] The invention relates to the field of plastic coloring, in particular to a polyolefin masterbatch with infrared reflection effect, and a preparation method of the masterbatch. Background technique [0002] Generally, tents and sunshade nets used outdoors do not have infrared reflection function. Although the colors are very close to the natural world, the target is exposed under the infrared imager of high-altitude helicopters in the military, and ordinary pigments are not available. Or it rarely has the ability to reflect infrared light. People working under such a sunshade net, because the sunshade net absorbs most of the sun's heat, it looks very stuffy. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a polyolefin masterbatch with infrared reflection effect. The masterbatch has infrared camouflage function and cooling effect. [0004] The technical scheme adopted by the present invention is: [000...
