Allergy-free thermoset powder coating

Abstract

The invention relates to an allergy-free thermoset powder coating. The allergy-free thermoset powder coating comprises the following raw materials in parts by weight: 30-65 parts of FEVE fluorocarbonresin, 30-65 parts of polyester resin, 3-8 parts of a poly-polyisocyanate curing agent, 20-40 parts of diatomite, 20-40 parts of calcium carbonate, 0.5-3 parts of rutile nano-titanium dioxide, 0.5-3 parts of a leveling agent, 0.2-2 parts of an allergy-free plant extract, 0.1-0.5 part of pigment and 0.1-1 part of a degasser. According to the provided allergy-free thermoset powder coating, the fluorocarbon resin is compounded with the polyester resin, the diatomite and the allergy-free plant extract are added, and therefore, the allergy-free thermoset powder coating which is suitable for wall coatings of dwellings of people with allergic constitution and children.

Description

technical field [0001] The invention belongs to the field of thermosetting powder coatings, in particular, the invention relates to a hypoallergenic thermosetting powder coating. Background technique [0002] With the continuous improvement of people's requirements for building comfort and health, the heat insulation, sealing and safety of the building itself have been paid more and more attention. The qualified rate of air quality in newly renovated houses in my country is less than 20%. The main reason is that various furniture and floors contain a large amount of adhesives and coatings, which emit volatile substances such as formaldehyde, organic solvents, and styrene monomers. Cause indoor air pollution, make health be seriously threatened. For people with special constitutions (such as allergies and infants), it is necessary to develop safe and anti-allergic coatings, which has become a research hotspot for many coating manufacturers, such as German latex paint Schnavor...

AI Technical Summary

Problems solved by technology

The qualified rate of air quality in newly renovated houses in my country is less than 20%. The main reason is that various furniture and floors contain a large amount of adhesives and coatings, which emit volatile substances such as formaldehyde, organic solvents, and styrene monomers. Causes indoor air pollution, which seriously threatens health

Polyester powder coating is a widely used thermosetting powder coating, which already accounts for about 70% of the total output of powder coatings. It has the advantages of low cost, no pollution, energy saving, long service life, etc., but its weather resistance is weaker than that of fluorocarbon resin
