Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a roller coating process of PU paint, which solves the problem that common substrate boards are painted by paint spraying method, which will produce a large number of atomized paint droplets, and the paint will be scattered into the air. More, without wasting paint, and it is not conducive to the health of the staff, and the substrate board lacks test confirmation in the traditional coloring process, which can easily cause coloring errors

Abstract

Disclosed is a roll coating process for PU paint, specifically comprising the following steps: (1) inspection and basic chamfering of a substrate; (2) sanding of the substrate; (3) roll coating of primary colored paint; (4) basic processing of bottom color drying; (5) roll coating of secondary colored paint; and (7) drying. The present invention relates to the technical field of decorative sheets.By roll coating test and inspection of a test board, the roll coating process for the PU paint effectively prevents chromatic aberration caused by shortage of tests; by means of roll coating of two colored paint, the dripping of a lot of atomized paint caused by spraying is prevented, the waste of the paint is reduced, the utilization rate of the paint is increased, the color precision after coating is improved, and the cost is indirectly reduced; and by means of inspection, chamfering and sanding of the substrate, the surface of the substrate is sufficiently prepared for roll coating and coloring, so that the subsequent roll coating and coloring effect is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of decorative panels, in particular to a roller coating process of PU paint. Background technique [0002] Decorative board is a kind of man-made board. It is a thermosetting laminated plastic made of high-temperature and high-pressure adhesives after chemical treatment with a variety of special papers. The board surface has various wood grains or patterns, bright and smooth, bright and beautiful, and has high wear resistance Good physical properties such as heat resistance, cold resistance and fire resistance. The walls and roofs of many high-end houses, well-made cabinets, cabinets, tables, beds, workbenches for precision instruments, laboratory test benches, TV sets, radios and other shells of broadcasting and telecommunications equipment, mostly use this new type of material. Decorative plates. The base plate is produced with high-density technology, the material is dense, the water absorption rate is...
