Method for fast dyeing on European oak floor by utilizing inorganic compounds

Abstract

The invention relates to a method for fast dyeing on European oak flooring by utilizing inorganic compound. The method includes the following steps of (1), substrate and European oak veneer veneering;(2) European oak floor machining treatment; (3) roller coating of an acetic acid aqueous solution; (4) roller coating of a sodium hydroxide aqueous solution; and (5) UV coating. The method has the beneficial effects that firstly, the requirements for large equipment and a special environment do not exist, dyeing can be performed under a normal temperature, the steps are simple, and the processingperiod is short; secondly, dyeing liquid is low in cost and easy to acquire, the whole dyeing process is nontoxic and harmless, and the method completely conforms to the green and environment-friendly concept under the condition that cost is lowered; thirdly, the acetic acid aqueous solution is favorable for flowing and diffusing of a dyeing agent into wood, the permeability of the surface of thewood floor is improved, secondly, the exchanging effect of a sodium hydroxide dyeing agent and acetic acid is high in the later period, and the color fastness and the uniform dyeing performance of the dyeing agent are better; and fourthly, the surface of the European oak floor is subjected to sodium hydroxide dyeing treatment, the size stability of the floor is improved, and the warping conditionof the floor is reduced.

Description

technical field [0001] The invention relates to a method for quickly dyeing European oak floors by using inorganic compounds, and belongs to the technical field of wood dyeing and finishing. Background technique [0002] With the development of science and technology and material processing industry, wood resources are used as raw materials, and their application scope is becoming more and more extensive. The material properties constructed by the structure and chemical composition of wood resources are becoming more and more popular, especially the natural environmental protection performance. However, due to the shortage of wood and the monotonous color of wood itself, it is increasingly unable to meet people's material needs. Therefore, wood has been dyed to enrich the decorative properties of wood. [0003] However, acid dyes, reactive dyes, and synthetic dyes are the most widely used in wood dyeing. After the chemical treatment of wood in the early stage, the wood is dy...
