Method for manufacturing construction composite panel with sedimentary deposit

Abstract

The invention relates to a production method of a construction composite board with a deposition layer and comprises the steps of preparing non-metal core layer, preparing two metal substrates, continuously forming deposition layer, combining the substrates to the core layer; the continuously forming of the deposition layer accords to the physical gas phrase deposition principle and a deposition layer of 0.3 to 10 Mum is formed on the surface of at least a substrate; and the deposition layer is chosen from at least one of the titanium, copper, chrome, zinc, aluminum, platinum, gold, silver, nickel, titanium nitride, aluminum nitride, titanium aluminum nitride, chromium nitride, silicon dioxide and titanium dioxide. The deposition layer formed though utilizing the physical gas phrase deposition principle not only has excellent wear resistance, temperature resistance and corrosion resistance, but also can naturally produce color change by utilizing physical phenomenon to light produced by the thickness of a coating without any additive solvent, dye and additive.

Description

technical field [0001] The invention relates to a manufacturing method of a building composite board, in particular to a manufacturing method of a building composite board in which a deposition layer is formed on a substrate by a physical vapor deposition technique. Background technique [0002] In the past, such as building curtain walls, door panels, columns, beams, porches, billboards, wall panels, interior decoration, ceilings, building exterior walls, awnings, etc., in the manufacture of building panels, usually made of plastic, Metal and other materials form a substrate, and then coat a layer of fluorocarbon coating on the surface of the substrate. The above-mentioned fluorocarbon coating usually includes: resin forming the main component of the coating film, pigments that make the coating film colorful, and solvents for easy coating. And various additives to improve the coating workability and the integrity of the coating film. Wherein the resin usually comprises: 70...

AI Technical Summary

Problems solved by technology

[0004] In the past manufacturing process of building composite boards, two resins were mixed with isophorone solvent, and pigments and additives were added to form a coating, and then the coating was coated on the surface of the substrate and then baked. Although it can protect the surface of the substrate However, in the manufacturing process, many chemical materials are used, especially the toxic isophorone solvent. Therefore, the manufacturing process of building composite panels with protective layers in the past has problems such as pollution and environmental burdens.
