Abstract

The invention discloses quick-drying and greening-proof unsaturated polyester furniture coating as well as production and construction processes thereof. The furniture coating includes a main ingredient A part, a B part containing cobalt iso-octoate and a C part containing methyl ethyl ketone peroxide, wherein the A part consists of the following components in parts by weight: 60-80 parts of unsaturated polyester resin, 0.01-0.03 part of a polymerization inhibitor, 10-25 parts of inorganic filler, 3-5 parts of zinc stearate, 4-8 parts of a solvent, 0.3-0.5 part of an anti-settling agent, 0.1-0.3 part of an antifoaming agent and 0.2-0.5 part of a flatting agent. The furniture coating disclosed by the invention adopts a composite accelerant consisting of cobalt iso-octoate and vanadium iso-octoate, and formed trivalent cobalt ion is represented as purple; a paint film is finally represented as quite light orange, a technical problem that the paint film of the unsaturated polyester furniture coating becomes green and a problem of slow drying at low temperature are solved; the furniture coating can well show texture of substrate when being applied to light-colored wood and stuck furniture, so as to keep color of the substrate, and the paint film is good in transparency.

Description

technical field [0001] The invention relates to an unsaturated polyester furniture coating, in particular to a fast-drying anti-greening unsaturated polyester furniture coating and its production and construction process. 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 PE unsaturated polyester furniture The curing reaction of coatings and unsaturated polyester furniture coatings 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 oxidation Reduction reaction, the cobalt salt in the accelerator decomposes the initiator to generate highly active fr...
