Manufacturing method of light-induced discoloration prevention wooden floor

Abstract

The invention discloses a manufacturing method of a light-induced discoloration prevention wooden floor. The preparation process of a surface board of the wooden floor sequentially comprises the following steps: veneers are stacked, the interval between veneer layers is 2-3 mm, a horizontal airflow channel is arranged among every four or five veneer layers, and a vertical airflow channel is arranged among every nine or ten veneer columns; the veneers are subjected to thermal treatment in a thermal treatment kiln at the temperature of 140-150 DEG C, and the preservation time of the highest temperature is 3-4 h; the veneers are cooled, specifically, atomized water is injected into the thermal treatment kiln to reduce the temperature in the thermal treatment kiln; color fading treatment is carried out, specifically, when the temperature in the thermal treatment kiln is reduced to 80+ / -2 DEG C-85+ / -2 DEG C, a sodium hydroxide solution is added in the injected atomized water, the concentration of the sodium hydroxide solution is 18-20%, and the addition quantity of the sodium hydroxide solution in per liter of atomized water is 300-400 g; the veneers are discharged out of the kiln, specifically, when the temperature in the kiln is reduced to 50-55 DEG C, injection of the atomized water is stopped, and the veneers are discharged out of the kiln after being naturally cooled to the room temperature; the water content is adjusted; and fixed-length manufacturing is carried out to obtain the surface board. The floor is free of slow discoloration and color difference and has the characteristic of long-lasting decoration effect.

Description

technical field [0001] The present application relates to the technical field of manufacturing methods of ground pavement materials, in particular to a manufacturing method of wooden floors with anti-light and discoloration properties. Background technique [0002] The floor is paved on the ground, and it is inevitable to encounter sunlight. Wooden materials will slowly discolor under the irradiation of visible light, and due to the anisotropy of wood and the differences between materials, the degree and speed of discoloration of different floors are different. There is a color difference between the blocks, which affects the decorative effect of the floor. [0003] Inducing and influencing factors of wood discoloration include wavelength and temperature. The current common wood floor anti-light and discoloration technology is mainly surface paint decoration, obviously, the effect is not ideal. Paint treatment has no protective effect on temperature-induced discoloration,...

AI Technical Summary

Problems solved by technology

At present, the common anti-light and discoloration technology of wooden floor is mainly surface paint decoration, obviously, the effect is not ideal

Paint treatment has no protective effect on temperature-induced discoloration, and the paint film formed by paint decoration has very limited interception effect on ultraviolet and visible light in sunlight, and as time goes by, the paint film itself will also develop under sunlight discoloration
