specific Embodiment approach 1

[0041] Specific embodiment one: a kind of environment-friendly wood veneer staining agent of this embodiment, it is made up of iron red solution or iron yellow solution, wherein, described iron yellow solution concentration is 20~60g / L, and described The concentration of iron red solution is 10-50g / L.

[0042] The environment-friendly wood veneer stain of this embodiment is suitable for the staining of all woods.

[0043] In this embodiment, wood veneers are dyed with water-insoluble iron red and iron yellow pigments, which has the advantages of non-toxic production process, environmental protection, non-fading products, and hydrophobicity. In addition, the product is used outdoors, and the pigment is not easy to be lost in the rain, which is friendly to the environment.

[0044] In this embodiment, the water fastness of the two pigments after being treated with iron yellow and iron red is extremely high.

specific Embodiment approach 2

[0045] Embodiment 2: This embodiment differs from Embodiment 1 in that: the concentration of the iron yellow solution is 40-60 g / L, and the concentration of the iron red solution is 30-50 g / L. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0046] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the concentration of the iron yellow solution is 50 g / L, and the concentration of the iron red solution is 40 g / L. Others are the same as in the first or second embodiment.

Abstract

The invention discloses a dyeing method of an environment-friendly wood veneer dyeing agent, and relates to a dyeing method of a wood veneer dyeing agent. The invention mainly solves the problems that an exiting dye is large in water solubility and high in leachability, dyed color is unstable, and an existing dyeing method is complex in process and high in equipment demand to cause environmental pollution and is not suitable for large-scale production. The dyeing method disclosed by the invention comprises the following steps of: first bleaching a veneer by means of characteristic of non-toxicity of CH3COOOH; and then, with the bleached veneer as a base material, dyeing the base material by two pigments, namely, iron oxide red and iron oxide yellow. According to the method disclosed by the invention, the dyed veneer is bright and full in color, high in water fastness of pigments, strong in hydrophobicity and extremely less in damage to wood. The dyeing method is low in equipment demand, easy to operate and strong in controllability, is suitable for large-scale industrial production, and has an extremely good actual application prospect.

Description

technical field [0001] The invention relates to the field of wood dyeing, in particular to an environment-friendly dyeing method for wood veneers. Background technique [0002] Wood dyeing is to use physical or chemical methods to combine dyes with wood to change the color of wood, so as to enrich its visual effect and increase the added value of wood. Due to the shortage of wood resources in recent years, in order to make up for the precious wood, the imitation precious wood obtained by dyeing some middle and low-grade wood has attracted much attention. Among them, dyeing with dyes is a relatively traditional process. However, the dye has high water solubility and high loss, which makes the color of the product unstable. At the same time, the dye will pollute the water after the dye is lost, and the process is relatively complicated. [0003] At present, Weixiang uses pressurized and decompressed processes to dye wood, and the process is as follows: [0004] Add the wood...
