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 of lowering down temperature.
Description
Technical field
The present invention relates to field of plastic coloring, be specifically related to a kind of polyolefin color masterbatch with infrared reflection effect, and the preparation method of this Masterbatch.
Background technology
The tent of general outdoor use, sunshade net etc. are owing to not having the infrared reflection function, although the color that naked eyes are regarded as very closely with nature, but target just exposes undoubtedly under the infrared thermoviewer of military high and medium vertiplane, and common pigment is due to the ability that there is no or seldom have reflects infrared light, the people works under such sunshade net, because sunshade net has absorbed most sunlight heat, seem very sultry.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of polyolefin color masterbatch with infrared reflection effect, and this Masterbatch had both had infrared rays camouflage function, had again cooling effect.
The technical solution adopted in the present invention is:
A kind of polyolefin color masterbatch with infrared reflection effect is comprised of the component of following weight percent: vector resin 40 ~ 85%, infrared reflection pigment 5 ~ 35%, color matching pigment 0 ~ 15%, dispersion agent 2 ~ 15%, antiaging agent 5 ~ 10%.
Described vector resin is acrylic resin (PP) or polyvinyl resin (PE).
Described infrared reflection pigment is that C.I. indigo plant 28, C.I. indigo plant 36, C.I. are green 50, C.I. is green 60, one or more in C.I. Huang 53, C.I. Huang 164, C.I. Huang 216, C.I. palm fibre 24, C.I. palm fibre 29, C.I. palm fibre 33.Infrared reflection pigment can be at infrared region reflected infrared consumingly, to reach the effect of infrared rays camouflage and cooling.The spectral reflectance curve of C.I. palm fibre 24 as shown in drawings, it is at the infrared region of 700-2500nm wavelength reflected infrared effectively, total solar reflectance TSR is 60%, and the temperature rise that produces after panchromatic absorption solar radiation is that heat accumulation HBU is 19 ℃ (the panchromatic heat accumulation HBU of non-infrared reflection pigment can reach degree more than 40).
Described color matching pigment is comprised of the component of following weight percent: titanium dioxide 0 ~ 100%, pigment dyestuff or mineral dye 0 ~ 100%, the pigment of namely matching colors can be all titanium dioxide, can be all pigment dyestuff or mineral dye, can be also both combinations, wherein titanium dioxide is Rutile type Titanium Dioxide, pigment dyestuff is azo pigment, phthalocyanine pigment, encircles one or more in pigment more, and mineral dye is one or both in carbon black pigment, ultramarine pigment.Color matching is in order to allot consistent with environment under visual inspection or actual required color adding of pigment.
Described dispersion agent is comprised of the component of following weight percent: polyethylene wax 0 ~ 100%, ethylene bis stearic acid amide (EBS) 0 ~ 100%, Zinic stearas 0 ~ 100%, be dispersion agent be in above-mentioned three kinds any one, or the wherein combination of two kinds, or the combination of three kinds.The fusing point of described polyethylene wax is that 100 ~ 106 ℃, molecular weight are 3000 ~ 5000.The fusing point of described ethylene bis stearic acid amide is 140 ~ 150 ℃.That ethylene bis stearic acid amide has is dispersed strong, usage quantity is few and have lubricant concurrently and the characteristics of brightening agent, can give the appearance of the level and smooth light of plastics.
Described antiaging agent is one or more in UV light absorber, oxidation inhibitor, photostabilizer.Ageing-resistant Main Function is the living radical in absorbing material, stops material aging, improves material property.
Another technical problem to be solved by this invention is to provide above-mentioned preparation method with polyolefin color masterbatch of infrared reflection effect.This preparation method is: take in proportion each component, mix 10 ~ 20min after mixing in rotating speed is the high-speed mixer of 800 ~ 1500r/min, adopt twin screw extruder, screw speed is 100 ~ 300r/min, and temperature is controlled at 160 ~ 200
oC carries out extruding pelletization, through cooling, the oven dry after make Masterbatch of the present invention.
Sunlight is a kind of hertzian wave, is divided into visible light 400nm-700nm and invisible light.Invisible light mainly comprises ultraviolet ray and infrared rays 700-2500nm.Shining has nearly 5% to be ultraviolet ray in the solar radiation of body surface, ultraviolet ray is mainly polymkeric substance and absorbs, and wherein UV light absorber and titanium dioxide etc. can be plastics protection is provided.Have simultaneously nearly 50% to be infrared rays, the result that produces under infrared ray radiation is exactly the absorption of radiation and gathering of additional heat.Be subjected to for a long time the illumination irradiation can make color, gloss and other mechanical property variation of plastics, and the product surface temperature can raise than envrionment temperature a lot.Add the polyolefin plastic products after infrared reflection pigment can the usable reflection infrared rays, thus make its under the infrared imaging instrument can with physical environment in the woods be shown as the same color, make it can reach the camouflage effect; Simultaneously can reduce the product surface temperature under illumination, reach cooling-down effect.
When the polyolefin color masterbatch with infrared reflection effect of the present invention is used in the exterior product such as sunshade net, the one, have extraordinary camouflage effectiveness under the infrared imaging instrument, can show with physical environment in leaf be the same color, and there is no this effect fully with other product as pigment production such as phthalocyanine blues; The 2nd, its surface temperature is than 2-4 ℃ of the product decline for preparing as pigment dyestuffs such as phthalocyanine blues with other.These two kinds of effects make product have fabulous Social benefit and economic benefit.
The plastics that Masterbatch of the present invention is made have reflected infrared camouflage function, can be widely used in the tent, the sunshade net that use in the environment such as outdoor forest, all can use on military, civilian, can also reduce surface temperature when reaching camouflage, reach the energy-conserving and environment-protective effect, the work-ing life that while aging-resistant characteristics have effectively improved product.
