Problems solved by technology

The existing teak floor color change method generally adopts sunlight irradiation, but this method is easily limited by the site and weather, and the sunlight irradiation time is long and the efficiency is low
In addition, part of the surface of the teak floor that has been color-changed by sunlight often has obvious black lines and spots, and the color-changing effect is not ideal.

Embodiment Construction

[0016] Example. In the present invention, the surface of the teak plain board is soaked with clear water with a pH value of 7. The teak plain board is an unpainted wooden floor, and the wet teak plain board is irradiated by ultraviolet light with a wavelength of 300 nanometers , in order to achieve the color change of the teak floor plain board, the irradiation temperature is 700°C when the ultraviolet light is irradiated, the teak plain board is soaked and the ultraviolet light is irradiated, and it is repeated 4 times for a total of 2.5 minutes. The teak is irradiated by ultraviolet light through the conveyor belt, and the transmission speed of the conveyor belt is 17.5 m / min; the chromophoric groups in the wood, such as methoxyl, carboxyl, hydroxyl, vinyl, etc. Photooxidation reaction and thermal oxidation reaction occur, thereby changing the original color of wood; now, high-energy and unique wavelength ultraviolet light is used to irradiate the chromophore in the wood to ...

Abstract

The invention discloses a color-changing method of a teak wood floor. The color-changing method carries out ultraviolet irradiation with the wavelength of 280 to 400 nanometers to the teak wood floorwith immersed surface so as to achieve color changing of the teak wood floor. The color-changing method is not limited by fields and weather, has time color-changing time, high efficiency and excellent color-changing effect and obviously reduces the black patterns and spots on the surface of the teak wood floor after changing color.

Description

technical field [0001] The invention relates to a processing method of a wooden floor, in particular to a method for changing the color of a teak floor. Background technique [0002] There are chromophoric groups in wood, such as methoxy, carboxyl, hydroxyl, vinyl, etc., under certain light and temperature conditions, photooxidation and thermal oxidation reactions will occur, thereby changing the original color of wood. Existing teak floor color change method generally adopts sunlight irradiation, but this method is easily subject to the limitation of site and weather, and the sunlight irradiation time is long, and the efficiency is low. In addition, part of the surface of the teak floor that has been color-changed by sunlight often has more obvious black lines and spots, and the color-changing effect is not ideal. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for changing the color of the teak floor....
