Chinese oak plate archaizing treatment method

Abstract

The invention belongs to the technical field of plate processing, and particularly relates to a Chinese oak plate archaizing treatment method. The method comprises the following steps that a Chinese oak plate is arranged in drying equipment provided with dry balls and wet balls to be dried and then arranged in a room-temperature pig blood extract diluent for vacuum impregnation, and the impregnated Chinese oak plate is irradiated with intensive pulse light; after completion of irradiation, water vapor is pumped in, the temperature of heating treatment is 130-140 DEG C, and the treatment time is 40-60 min; and after heat treatment is completed, the Chinese oak plate, a poplar core strip, a rotary-cut poplar backplate and powdery urea-formaldehyde glue are assembled and pressed into a composite floor. Compared with the prior art, the method has the following advantages that through the method, the Chinese oak plate present the rosewood color characteristics after being treated under thelow temperature condition, the wood color difference defect is overcome, the effect that the flexure strength and the elasticity modulus of the Chinese oak plate remain at a high level is ensured, andthe Chinese oak plate has good paint film adhesive force.

[0002] Wood is a kind of natural biomass material. Its internal cell lumen, intercellular space, and microcapillaries, vessels, pits and other pores in the cell wall are connected in series and parallel to form a complex capillary structure system inside wood. Different processing methods of wood It has a great influence on the performance of wood; with the continuous research on wood processing, it has a reasonable structure, beautiful and comfortable, saves precious wood, and has a good market prospect for solid wood composite flooring. Select high-quality wood with hard texture, beautiful texture, and no color difference, which greatly limits the range of material selection for the surface plate. In the prior art, in order to reduce the color difference of the surface plate, improve corrosion resistance and dimensional stability, the surface plate Carry out high-temperature heat treatment, the decorative surface plate after treatment is strong, but the production of existing antique base plate mainly achieves antique effect through techniques such as texture planing, wire drawing, sandblasting, dyeing, and production efficiency is low, and in the prior art mainly uses oak Wood is used as the main raw material for old-fashioned antique treatment. The research shows that with the increase of heat treatment temperature and time extension, the lightness of the oak wood surface plate decreases obviously, and the chromaticity index of red-green axis and yellow-blue axis chromaticity index increase first. Afterwards, it decreases, but the range of change is not large. The color difference from the conventional technology increases with the increase of the treatment temperature and the extension of the treatment time. If the distribution characteristics of the color space of the color parameters of mahogany wood are to be satisfied, a higher temperature is required. The time is also longer; in actual use, it can be seen that with the increase of heat treatment temperature, it has a great influence on the mechanical properties of the processed plate, and its bending strength decreases with the increase of treatment temperature, which may affect its normal use. However, if the treatment temperature is too low, it will affect its appearance. Therefore, it is necessary to further study the antique method of oak wood.
