The invention discloses an electrostatic spraying polyurethane varnish, comprising a primary agent and a diluent, wherein the primary agent comprises alkyd resin, diacetone alcohol, acetone, propylene glycol methyl ether acetate and a conductive agent; the diluent comprises propylene glycol methyl ether acetate, xylene, cyclohexanone, trimethylbenzene and a conductive agent. After the conductive agent is added, not only are excellent decorative and protective effects of the traditional PU dual-component furniture lacquer reserved, but also the resistance is reduced, the electrostatic spraying polyurethane varnish is applicable to electrostatic spraying, and especially, electrostatic spraying can be conveniently carried out on a complicated work-piece, so that the construction quality and the construction efficiency can be greatly improved.
Description
technical field [0001] The invention relates to a paint, in particular to an electrostatic spraying polyurethane varnish. Background technique [0002] Polyurethane paint is polyurethane paint. It has strong paint film, full luster, strong adhesion, water resistance, wear resistance and corrosion resistance. It is widely used in high-grade wooden furniture and can also be used on metal surfaces. Polyurethane coatings are divided into two-component polyurethane coatings and one-component polyurethane coatings. Two-component polyurethane topcoat paint is generally composed of isocyanate prepolymers (also known as low molecular carbamate ester polymers) and hydroxyl resins, commonly known as curing agent components and main agent components. Generally, they have good mechanical properties, high solid content, and good performance in all aspects. It is a kind of coating variety with great development prospect at present. The main application directions are wood coatings, au...
