Baking varnish machining process

Abstract

The invention discloses a baking varnish machining process. The baking varnish machining process comprises the following steps: (a) surfaces of furniture parts are sprayed by using piano paint PE rawmaterials; the PE spraying operation is continued by 5-7 times; and PE paint films reach thicknesses of 2.5-3 mm during painting to meet sanding and polishing demands; (b) the sprayed furniture partsare heated to totally cure PE paint film; and (c) the furniture surfaces are polished. Manufactured piano baking varnish furniture is higher in highlight, mirror surface and hardness, and is clear anduniform in color; finished paint films can reach 1 mm thicknesses; and paint surfaces can achieve repairability.

Description

technical field [0001] The invention belongs to the technical field of furniture coating, and in particular relates to a paint baking process. Background technique [0002] The common PU bright paint film in the industry is easy to be less than 0.2mm in thickness and 1.5H in hardness, the paint film is easy to yellow, age and fall off, and there are apertures, swirls or wrinkles on the surface, without mirror effect; the common PE bright paint in the industry The production is often a combination of PE bottom + PU surface, the paint film is easy to cause delamination, the gloss is easy to fade, and the color sense lacks clarity. It is difficult to realize the production of colorful piano paint with current domestic PE raw materials (except transparent and black) . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a baking varnish processing technology for the deficiencies of the above-mentioned prior art, which ha...
