Abstract

The invention discloses anti-greening unsaturated polyester furniture coating. The anti-greening unsaturated polyester furniture coating comprises a main agent, an accelerant containing cobalt iso-octoate and an initiator containing methyl ethyl ketone peroxide, wherein the main agent comprises the following components in parts by weight: 60 to 80 parts of unsaturated polyester resin, 0.01 to 0.03 part of a polymerization inhibitor, 10 to 25 parts of an inorganic filler, 3 to 5 parts of zinc stearate, 4 to 8 parts of a solvent, 0.3 to 0.5 part of an anti-settling agent, 0.1 to 0.3 part of a defoaming agent, 0.2 to 0.5 part of a flatting agent and 0.1 to 0.3 part of a phosphate / ammonium compound dispersing agent. A phosphate / ammonium compound and cobalt ions form a complex, the trivalent cobalt ions are claret, and the coating film finally embodies extremely light orange, so the technical problem that the unsaturated polyester furniture coating film is greened is solved, the texture of the substrate can be shown during coating of light solid wood and paster furniture, the color of the substrate is maintained, and the coating film has good transparency.

Description

technical field [0001] The invention relates to an unsaturated polyester furniture coating, in particular to an anti-greening unsaturated polyester furniture coating. Background technique [0002] Unsaturated polyester furniture coatings can be thickly coated at one time, with full paint film, good hardness, solvent resistance, filling and anti-collapse properties, and are widely used in the furniture industry; furniture coatings for general furniture coating are mainly unsaturated polyester furniture coatings , The curing reaction of unsaturated polyester furniture coating is a free radical copolymerization reaction. During the curing reaction, it is necessary to add accelerator cobalt naphthenate or cobalt isooctanoate (blue water) and initiator methyl ethyl ketone peroxide (white water), through redox Reaction, the cobalt salt in the accelerator decomposes the initiator to generate highly active free radicals, which attack the unsaturated double bonds in the molecular cha...
