Abstract

The invention relates to an infrared-reflection nanometer titanium dioxide powder coating and a preparation method thereof. The powder coating comprises, by mass, 30-40% of an infrared-reflection nanometer titanium dioxide composite material, 25-30% of thermosetting acrylic resin, 25-30% of thermosetting polyester resin, 5-10% of blocked diisocyanate, 1-2% of a leveling agent and 0.5-1% of an antifoaming agent. The preparation method comprises the following steps: A, adding nanometer raw materials into a stirrer to obtain the infrared-reflection nanometer titanium dioxide composite material; B, adding the thermosetting acrylic resin, the thermosetting polyester resin, the blocked diisocyanate, the leveling agent and the antifoaming agent into the stirrer, carrying out high-speed stirring in the stirrer, and then adding the composite material obtained in step A to obtain a mixture; C, adding the mixture into a twin-screw extruder, and granulating and cutting the mixture to obtain masterbatches; and D, crushing and sieving the master batches to obtain the infrared-reflection nanometer titanium dioxide powder coating. The infrared-reflection nanometer titanium dioxide powder coatingcan efficiently reflect solar infrared heat radiation, and meets the requirement of long-term outdoor natural environment erosion.

Description

technical field [0001] The invention belongs to the technical field of chemical production, and relates to an anti-infrared nanometer titanium dioxide powder coating and a preparation method. Background technique [0002] With the increasingly strict regulations on VOC restrictions around the world, the development of environmentally friendly coatings is an important research direction at present. Because powder coating has no organic solvent, 100% solid coating, and no VOC emission, it is a new type of environmental protection coating. The construction only needs thermal spraying, one-time film formation, which simplifies the process and is more durable. Therefore, powder coating not only has excellent coating performance. Layer quality, and no environmental pollution, saving resources. [0003] The commonly used acrylic powder coating has the advantages of strong weather resistance, good chemical corrosion resistance, and good color retention, but it needs a curing agent ...
