Water-based paint spraying process

Abstract

The invention discloses a water-based paint spraying process which comprises the following steps: performing water-based color coating for the first time with the coating weight of 120-150g / m<2>, drying after coating, performing water-based color fixing primer coating with the coating weight of 110-120g / m<2> after drying, drying after coating, and performing water-based color fixing primer sandingafter drying; carrying out water-based primer coating with the coating weight of 140-150g / m<2> after sanding, and performing drying sanding after coating; and after sanding, performing water-based finish paint spraying with the coating weight of 130-160 g / m<2>. The water-based pigment is prepared from water-based acrylic acid, a water-based base material, a water-based activating agent, purifiedwater and color; in addition, the water-based pigment can be directly coated on wood veneer or logs; and aqueous sealing primer is not needed, so that a production process is simplified, production cost is reduced, production efficiency is improved, the water-based color is directly roller coated or sprayed on the wood veneer or the log, the phenomena of color separation and yellowing caused by ethanol volatilization are effectively avoided, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of water-based paint spraying, in particular to a water-based paint spraying process. Background technique [0002] Any coating that uses water as a solvent or as a dispersion medium can be called a water-based paint. Water-based paint includes three types: water-soluble, water-diluted, and water-dispersed (latex paint). [0003] The water-based paint coating process is a new type of wood veneer water-based paint application technology, which is mainly used in furniture, doors, windows, wall panels, etc. The mixed oil products on the market generally include PU bottom PU surface, NC bottom NC surface and PU bottom water-based surface. , the use of oily polyester paint is mostly oily polyester paint, its environmental protection performance, safety performance, benzene and VOC release are very high in the later stage, which not only pollutes the environment, but also is extremely unsafe; and in the use proce...

[0003] The water-based paint coating process is a new type of wood veneer water-based paint application technology, which is mainly used in furniture, doors, windows, wall panels, etc. The mixed oil products on the market generally include PU bottom PU surface, NC bottom NC surface and PU bottom water-based surface. , the use of oily polyester paint is mostly oily polyester paint, its environmental protection performance, safety performance, benzene and VOC release are very high in the later stage, which not only pollutes the environment, but also is extremely unsafe; and in the use process of these water-based paints, because water-based paints cannot Directly acting on veneer and logs, it is necessary to use ethanol-based water-based paint for wood primary isolation, and water-based paint must be diluted with ethanol-containing water-based paint, so the operation is extremely harmful to the human body, and the ethanol volatilizes in the later stage to produce color separation. Ethanol volatilizes, resulting in flaky or speckled color, especially dark color is the most serious, turning yellow and mottled

In addition, due to the low adhesion of water-based paint, there will be delamination of water-based paint
