Problems solved by technology

This process not only takes a long production cycle, consumes a lot of paint and manpower, increases the manufacturing cost of the board, and reduces production efficiency, but also because of the large amount of paint used in the production process, it will cause the furniture board to have a paint smell, which will affect the air quality and is not environmentally friendly. , causing customers to emit paint smell for a long time during the use of furniture
At the same time, because the back of the furniture board cannot be closed, when the air humidity is high in the rainy season, it will absorb moisture and cause the board to expand
Deformation of furniture panels leads to after-sales maintenance, which further increases the cost of furniture

Embodiment 1

[0038] Step 1. Glue adjustment

[0039] Put the protein glue into the container, add soybean powder, the mass ratio of protein glue and soybean powder is 10:5, stir well to make it sticky and free of particles;

[0040] Step two, glue

[0041] Pour the prepared glue into the glue applicator and adjust the amount of glue to 200g / m 2 , apply glue on the ash density board, the plain board before the glue is as figure 1 As shown, the board after gluing is as follows figure 2 As shown, the smear is even and the penetration effect is good;

[0042] Step three, glue

[0043] The press is preheated, the pressure is 12mpa, the temperature is 120°C, and the hot pressing time is 70 seconds, so that the glue can fully fill the cell pores of the wood veneer. Under the action of temperature and pressure, the soybean protein glue can fully fill the cell pores and then solidify instantly;

[0044] Step 4: Spray topcoat, the effect is as follows image 3 As shown, the paint surface is a...

Embodiment 2

[0046] Step 1. Glue adjustment

[0047] Put the protein glue into the container, add soybean powder, the mass ratio of protein glue and soybean powder is 10:3, stir well to make it sticky and free of particles;

[0048] Step two, glue

[0049] Pour the prepared glue into the glue applicator, and adjust the amount of glue to 180g / m 2 , glued on birch chipboard;

[0050] Step three, glue

[0051] The press is preheated, the pressure is 15mpa, the temperature is 120°C, and the hot pressing time is 75 seconds, so that the glue can fully fill the cell pores of the wood veneer. Under the action of temperature and pressure, the soybean protein glue fully fills the cell pores and then solidifies instantly;

[0052] Step 4, spray finish paint, effect is the same as embodiment 1.

Embodiment 3

[0054] Step 1. Glue adjustment

[0055] Put the protein glue into the container, add soybean powder, the mass ratio of protein glue and soybean powder is 10:1, stir well to make it sticky and free of particles;

[0056] Step two, glue

[0057] Pour the prepared glue into the glue applicator, and adjust the amount of glue to 150g / m 2 , apply glue on the rubber wood OSB board;

[0058] Step three, glue

[0059]The press is preheated, the pressure is 15mpa, the temperature is 110°C, and the hot pressing time is 80 seconds, so that the glue can fully fill the cell pores of the wood veneer. Under the action of temperature and pressure, the soybean protein glue can fully fill the cell pores and then solidify instantly;

[0060] Step 4, spray finish paint, effect is the same as embodiment 1.

Abstract

The invention discloses a primer disposal method for a wood veneer panel. An oil paint primer is replaced by soybean protein glue, and the wood veneer panel is coated by means of a gluing machine. According to the primer disposal method for the wood veneer panel, by means of a characteristic that formaldehyde-free soybean protein glue is good in heating and curing strength, the wood veneer panel is coated by means of the gluing machine, and the soybean protein glue is roll-coated by means of a heating machine of a press, so that the hot pressing time is short, the smearing is uniform, the permeating effect is good, the production period is shortened, the work efficiency is improved, and meanwhile, air is isolated and moisture is prevented from being sucked. Therefore, the panel is in a stable state for a long time, so that the perfection of furniture is guaranteed and the service life of the furniture is prolonged, too. The soybean protein glue which is formaldehyde-free and environmental-friendly is adopted, so that the production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of furniture wood veneer, board and floor production and processing, in particular to a primer treatment method for wood veneer boards. Background technique [0002] At present, in the processing of furniture wood veneer panels and floors, in the field of white paint spraying on plain boards, solid wood furniture wood veneer panels need to be primed and topcoated. Due to the presence of wood cell pores in the wood veneer, a large amount of paint is required to be filled as a primer to prepare for the subsequent topcoat. This process not only takes a long production cycle, consumes a lot of paint and manpower, increases the manufacturing cost of the board, and reduces production efficiency, but also because of the large amount of paint used in the production process, it will cause the furniture board to have a paint smell, which will affect the air quality and is not environmentally friendly. , As a result, ...
