preparation example Construction

[0025] The preparation method of the present invention comprises the following steps (the mass parts of each raw material are all based on the content of each component in the product):

[0026] 1) Mix water-based acrylic resin, co-solvent, film-forming aid, distilled water and thickener, and make a mother liquor with a high-speed stirring method with a stirring speed of 800-1500 rpm;

[0027] 2) Add coloring pigments and wetting and dispersing agents to the mother liquor in sequence, and disperse evenly in a medium-speed stirring manner with a stirring speed of 500-800 rpm to obtain a pre-dispersion;

[0028] 3) Grind the pre-dispersion to less than 50 microns, then add reflective carrier, metallic pigment, preservative, leveling agent and defoamer, and stir evenly to obtain an ultra-wide-angle high-brightness water-based environmentally friendly facade reflective coating.

Abstract

The invention discloses a super-wide high-brightness water-based environment-friendly facade reflective coating and a preparation method thereof, and has the aims that the prepared coating is safe and non-toxic, environmentally friendly, high in adhesive force, good in reflective performance, and good in optical radiation resistance and ageing property, and the preparation method is simple in process and easy to implement. The coating and the preparation method are characterized in that the coating comprises the components in parts by mass: 20 to 30 parts of water-based acrylic resin, 1 to 5 parts of coalescing agent, 0.1 to 10 parts of cosolvent, 10 to 20 parts of metallic pigment, 10 to 15 parts of distilled water, 6 to 15 parts of coloring pigment, 20 to 60 parts of reflective carrier, and 1 to 3 parts of accessory ingredient, wherein the accessory ingredient adopts a mixture of a wetting dispersant, a flatting agent, a preservative, a thickening agent and a defoaming agent with any proportion.

Description

technical field [0001] The invention belongs to the field of traffic system engineering, and in particular relates to an ultra-wide-angle, high-brightness water-based environmentally friendly facade reflective coating and a preparation method thereof. Background technique [0002] Ultra-wide-angle high-brightness water-based environmental protection facade reflective coating is a new type of road safety marking material, with ultra-wide visibility, high-brightness reflective performance, bright color reflective effect, and high visibility in rainy nights. Super strong water-based environment-friendly materials, combined with special coating materials made of ultra-miniature color reflective elements, coated on the surface of objects, with strong adhesion, will form a complete high-strength reflective layer, with all-weather color reflective performance , and resistant to cold and high temperature, wind, frost, rain and snow. The viewing angle is greater than 120 degrees, hi...
