Problems solved by technology

[0002] At present, PE wax-containing polishing system is mostly used for surface coating of black piano lacquer. During the actual film formation process, paraffin wax floats on the surface of the paint film, making the surface dull. It must be sanded and polished in multiple passes to obtain a bright coating film. It is not practical for the surface coating of pianos with carvings, grooves, etc. Brittleness and other technical defects

Abstract

The invention discloses an environment-friendly PE gloss black piano lacquer, which comprises a main agent, a diluting agent, an accelerating agent and an initiator, wherein the main agent mainly comprises the following components in portion by weight: 75 to 85 portions of unsaturated polyester finishing paint resin, 0.2 to 0.5 portion of wetting dispersing agent, 0.8 to 1.1 portions of carbon black, 4 to 6 portions of hexamethoxymethyl melamine resin, 0.3 to 0.6 portion of anti-sagging agent, 0.02 to 0.04 portion of polymerization inhibitor, 0.2 to 0.4 portion of butanone, 13 to 17 portions of styrene, and 0.2 to 0.4 portion of levelling agent; the diluting agent mainly comprises 100 portions of the styrene; the accelerating agent contains 100 portions of cobalt naphthenate solution with6 percent of Co<2+>; and the initiator contains 100 portions of butanone peroxide solution with 10 percent of active oxygen. The environment-friendly PE gloss black piano lacquer can obtain a bright film coating without polishing, has better mechanical properties and fullness, is difficult to have cooling cracks, can solve the problem of northward transportation of south musical instruments, and simultaneously completely uses active diluting agent and is very favorable for environmental protection.

Description

technical field [0001] The invention relates to the field of unsaturated polyester paint, in particular to an environment-friendly polyester piano paint. Background technique [0002] At present, PE wax-containing polishing system is mostly used for surface coating of black piano lacquer. During the actual film formation process, paraffin wax floats on the surface of the paint film, making the surface dull. It must be sanded and polished in multiple passes to obtain a bright coating film. It is not practical for the surface coating of pianos with carvings, grooves, etc. Technical defects such as brittleness. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a PE glossy black piano lacquer for piano surface coating, which can obtain good mechanical properties, easy construction and excellent fullness without polishing. [0004] The technical scheme that the present invention solves the problems of the technologies...
