Abstract

The invention discloses paint with high ultraviolet and infrared ray shielding rates and a preparation method of the paint. The paint comprises the following components by weight percent: 20-30% of alcohol, 2-3% of 2-hydroxy-4-octyloxy benzophenone, 1-3% of polyamide resin, 25-30% of ferrite composite powder, 5-8% of propylgallate and the balance of polyurethane. The paint has excellent ultraviolet and infrared electromagnetic energy attenuation effects, can be prepared without using a great deal of rare and precious elements, and adopts waste blast-furnace slag as raw material, is low in production raw material cost and simple in production process, and has very high application prospect.

Description

technical field [0001] The invention relates to the technical field of paint compositions, in particular to a paint with a high ultraviolet and infrared shielding rate and a preparation method thereof. Background technique [0002] Application No. CN01102763.0 relates to an anti-ultraviolet and infrared energy-saving coating. Nano silicon dioxide NMSiO2-X is added to the paint. It is mainly composed of pure acrylic emulsion or styrene-acrylic emulsion, film-forming agent, titanium dioxide, nanometer, dispersant, defoamer, antifungal agent, leveling agent, pigment, and water. The coating can reflect 75-80% of the Ultraviolet and infrared rays of different wavelengths can greatly reduce the damage of ultraviolet rays to materials, and have the effects of anti-aging, anti-color reduction and heat insulation, and save energy consumption. The problems of the above-mentioned coatings are that the production cost is high, and the ultraviolet reflection degree of the coating needs...
