Problems solved by technology

However, due to the structural characteristics of hard wood and the hydrophobic effect, it is difficult for dye molecules to be dyed, and the color is very unstable. It will change and fade under the influence of light and climate.
The existing treatment method is to increase the amount of dye, and improve the coloring performance of wooden doors through vacuum pressure, microwave treatment, etc. However, after this treatment method, the color tone after dyeing is dull and single, and the color is deep, which does not meet the needs of consumers. Aesthetic needs for color

Abstract

The invention relates to the technical field of wood processing and treatment and discloses a method of improving dyeing properties of a hard wooden door. According to the method, a reinforcing agentobtained through preparation is added into a dye liquor, and after homogenization treatment for 20-30 minutes, dyeing treatment can be performed on the hard wooden door; the reinforcing agent emulsioncan lower surface tension of wood in contact with dyestuff, rapid absorption of the dyestuff by cellulose is promoted, the color of the dyestuff is maintained, and the wooden door obtained after dyeing has prominent optical stability and thermal stability and is suitable for all types of dyestuff (including acid dyestuff, basic dyestuff, reactive dyestuff and the like); nanoparticles are well dispersed, the wet rubbing fastness of the hard wooden door can be improved, and the hard wooden door has extremely good fastness to light, sublimation and sunlight; and besides, a hardening layer formedthrough calcium-based crystallization can protect the surface of a wooden structure, so that the waterproofness of a wood surface is improved, and the fastness to washing is high.

Description

technical field [0001] The invention belongs to the technical field of wood processing, and in particular relates to a method for improving the dyeing performance of hard wooden doors. Background technique [0002] Due to the advantages of strong plasticity, environmental protection and beauty of hard wood, it occupies a place in the furniture market, especially in the choice of wooden doors necessary for the family. Or fashionable and modern, doors with different decoration styles give consumers a wide choice space. [0003] The application of wood dyeing technology began in 1913. Since then, many scholars have done a lot of research on the basic theory and technology of wood dyeing, which has made the practical and industrialization of wood dyeing technology develop rapidly. Wood staining is an aspect of improving the visual properties of wood and is one of the avenues for decoration. Dyeing the wooden door can enrich the shape and decoration, so as to enhance the appear...
