Problems solved by technology

The reflective heat-insulating coating products in the prior art are mainly transparent, white and other high-brightness color reflective heat-insulating coatings. Heat insulation coatings generally have poor reflective heat insulation performance, which makes the color of reflective heat insulation coating products relatively single, and the colors are not rich enough to meet market demand

Embodiment 1

[0023] The water-based acrylic resin uses 35% pure acrylic emulsion (Zhengzhou Yuanding Chemical DR-60), 8% heat-reflecting polymer, 2% cellulose ether, 12% superfine heat-insulating powder, 8% hollow glass beads, 4% high refractive index pigment, 0.5% hydrophobic modified ammonium salt dispersant, 1% thick build defoamer, 1% non-ionic wetting agent, 1% antifreeze, 1% film forming agent, antiseptic 0.5%, the balance is water. The heat reflective polymer is composed of 40% acrylic polymer, 30% rutile titanium dioxide, 10% magnesium silicate and 20% water. To prepare army green reflective heat insulation coating, the dosage of high refractive index pigment is iron yellow: phthalocyanine blue = 9:8.

Embodiment 2

[0025] The water-based acrylic resin uses 50% pure acrylic emulsion (Zhengzhou Yuanding Chemical DR-60), 6% heat-reflecting polymer, 1% cellulose ether, 15% superfine heat-insulating powder, 10% hollow glass beads, High refractive index pigment 10%, hydrophobic modified ammonium salt dispersant 1%, thick build defoamer 1%, non-ionic wetting agent 1%, antifreeze agent 0.5%, film forming agent 0.5%, preservative 0.5%, the balance is water. The heat reflective polymer is composed of 50% acrylic polymer, 25% rutile titanium dioxide, 15% magnesium silicate and 10% water. To prepare iron red reflective heat insulation paint, only iron red is used as high refractive index pigment.

Embodiment 3

[0027] The water-based acrylic resin is made of pure acrylic emulsion (Zhengzhou Yuanding Chemical DR-60) 40%, heat-reflecting polymer 7%, cellulose ether 1.5%, heat-insulating filler 10% of ultra-fine heat-insulating powder, hollow glass beads 9%, 8% high refractive index pigment, 0.5% hydrophobic modified ammonium salt dispersant, 1% thick build defoamer, 1% non-ionic wetting agent, 0.5% antifreeze, 0.5% film forming agent, preservative 0.5%, the balance is water. The heat reflective polymer is composed of 55% acrylic polymer, 10% rutile titanium dioxide, 20% magnesium silicate and 15% water. To prepare navy blue reflective heat insulation coating, the dosage of high refractive index pigment is iron yellow: iron red: phthalocyanine blue = 5:8:10.

[0028] Prepare the proportions of Example 1, Example 2 and Example 3 with the same preparation method, specifically: add water and cellulose ether to the stirring tank according to their respective mass fractions, and stir at a s...

Abstract

The invention discloses a dark color reflective heat insulation paint. The dark color reflective heat insulation paint is characterized by comprising the following components by mass fraction: 35-50%of waterborne acrylic resin, 6-8% of a heat reflection polymer, 1-2% of cellulose ether, 10-15% of heat insulation filler, 4-10% of high refraction coefficient pigment, 8-10% of hollow glass beads, 4-5% of assistants and the balance water. The pigment is selected from iron red, iron oxide yellow and phthalocyanine blue. The preparation method includes: adding water and cellulose ether into a stirring kettle, performing low speed stirring for 10min, then adding the assistants and conducting medium speed stirring, then adding the heat insulation filler and pigment and performing high speed dispersion to make the fineness of the system less than or equal to 35 microns, adding waterborne acrylic resin and conducting medium speed stirring, then adding the heat reflection polymer and conductingmedium speed stirring, finally adding the hollow glass beads and conducting low speed stirring, thus obtaining the dark color reflective heat insulation paint. The obtained paint has heat insulation effect, also is dirt resistant, can be blended into various colors, is rich in color and strong in texture, even if a dark color is blended, the paint also has good reflective heat insulation effect, and can meet the decorative demand of the market for reflective heat insulation paint.

Description

technical field [0001] The invention relates to a reflective heat-insulating paint, in particular to a dark-colored reflective heat-insulating paint and a preparation method thereof. Background technique [0002] In recent years, the state has put forward higher requirements on energy saving and consumption reduction for the construction industry, and reflective heat insulating coatings with heat insulation properties have been paid more and more attention in the industry. Reflective heat insulation coatings have the dual functions of decoration and heat insulation. By efficiently reflecting sunlight to achieve heat insulation, they can significantly reduce the surface temperature of buildings exposed to solar heat radiation and reduce heat transmission into the room. The reflective heat-insulating coating products in the prior art are mainly transparent, white and other high-brightness color reflective heat-insulating coatings. Heat insulation coatings generally have poor ...
