Abstract

The invention discloses unsaturated dual-curable polyester black gloss finish paint special for musical instruments. The unsaturated dual-curable polyester black gloss finish paint is prepared from a main agent containing unsaturated polyester and alkyd resin, an initiator, a promoter and a diluent, wherein the main agent to the diluent to the initiator to promoter to a curing agent is 100:40:0.8-2.5:1-2.8:50-100, the main agent is alkyd resin, unsaturated polyester resin, butyl acetate and the like, the diluent is butyl acetate, styrene, toluene and the like, and the unsaturated dual-curable polyester black gloss finish paint can be obtained by proportionally mixing the main agent, the diluent, the curing agent, the initiator and the promoter. The problems of processing complexity and high flexibility of the musical instruments can be effectively solved, and the unsaturated dual-curable polyester black gloss finish paint is high in fullness, good in covering power, easy to polish, high in hardness and excellent in wood hole feeding effect and does not cause edge breakage and cracking after punching.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a special unsaturated dual-curing polyester bright black finish for musical instruments. Background technique [0002] Musical instrument topcoats usually require strong hiding power, high hardness, high gloss, high fullness, excellent adhesion, good transparency, and easy polishing, etc., which usually use unsaturated polyester paint. But existing unsaturated polyester varnish is used for the biggest problem of musical instrument and is: easily occur that paint can't go into wood hole, floats on the surface of wood hole, and the disadvantages such as the disadvantages of easy edge collapse when punching. Contents of the invention [0003] The purpose of the present invention is to provide a special unsaturated dual-curing polyester bright black topcoat for musical instruments to solve the problems in the prior art. [0004] The technical scheme that the present invention t...
