Problems solved by technology
[0005] Aiming at the deficiencies of the prior art, the present invention provides a method for powder coating of wood substrates, which solves the problem that in the construction process of the current powder coating, a good powder film must be formed after secondary spraying on the molding board, which reduces the Production efficiency also increases the cost of raw materials. Water-based paint primer is used as the sealing primer, which has the problem of poor sealing performance. During use, especially in an environment with high air humidity, it is easy to cause cracking and deformation of the board. During the powder coating process The degree of automation is low, which reduces production efficiency and cannot meet people's requirements

Abstract
The invention relates to the technical field of base material powder coating, and discloses a wood base material powder coating method which comprises the following steps: S1, base material treatment: adopting a medium density fiberboard as a base material; s2, edge coating; s3, the board surface is coated with UV primer in a roller mode, and during coating, the board surface sequentially passes through a sanding machine, a dusting machine, a conveyor, a putty coating machine, a three-lamp curing machine, a conveyor, a sanding machine, a conveyor, a double-roller coating machine, a double-lamp curing machine, a conveyor, a double-roller coating machine, an infrared leveling machine, a three-lamp curing machine and a conveyor; and S4, hole water injection. The oil-based UV white primer and the oil-based laser white primer are adopted for sealing, the water resistance is better than that of water-based paint sealing primer, the water resistance is better, the original two-time powder spraying forming is improved into one-side powder spraying forming, the product quality performance is qualified, the powder raw material cost is reduced, and the production efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of base material powder coating, in particular to a wood base material powder coating method. Background technique [0002] Powder coating is to use powder spraying equipment to spray powder coating onto the surface of the substrate. The powder will be evenly adsorbed on the surface of the substrate to form a powdery coating. Different final coating, the spraying effect of powder spraying is superior to spraying process in terms of mechanical strength, adhesion, corrosion resistance, aging resistance, etc., and the cost is also lower than that of spraying with the same effect. [0003] The current powder coating is more and more widely used, especially in the household industry, which is more and more recognized by people, but there are still the following problems in the construction process and performance of the powder: (1) During the construction of the powder, for the modeling board Parts must be spray...
