Problems solved by technology

However, due to the general permeability of existing dyes, the dyed veneer obtained by the above method has low color fastness, and generally fades after a short period of use, which affects the aesthetic effect of wood products.
In addition, the wear resistance of the surface of dyed veneer is poor, and the surface of dyed veneer is easily scratched
Therefore, there is the problem of lower color fastness in existing technology

Abstract

The invention discloses an acidic veneer dyeing material, and a preparation method and a dyeing process thereof. The acidic veneer dyeing material is prepared from, by weight, 10-15 parts of an anionic aliphatic polyurethane dispersoid, 4-6 parts of water-based acrylic resin, 35-40 parts of an acid dye, 0.5-0.8 part of dodecyltrimethylammonium chloride, 0.9-1.2 parts of cetyltributylammonium halide, 1.5-1.8 parts of C6-20 alkyl fatty alcohol, 0.3-0.6 part of C4-12 alkyl phenol, 8-11 parts of a naphthalene sulfonic acid formaldehyde condensation polymer, 0.6-1.0 part of isooctyl alcohol polyoxyethylene ether sulfate, 4.5-5.5 parts of a blocked water-based isocyanate cross-linking agent, 1.2-1.6 parts of monodisperse porous polymer microspheres and 18-22 parts of hard water. The preparationmethod comprises the following steps: sequentially mixing the components, and uniformly stirring the components. The dyeing process comprises: cleaning of veneer, negative pressure treatment, high-pressure dyeing, pre-drying, and drying for obtaining a dyed veneer finished product. The acidic veneer dyeing material has the characteristic that the color fastness can be effectively improved.

Description

technical field [0001] The invention relates to a dyeing material, in particular to an acidic veneer dyeing material and its preparation and dyeing process. Background technique [0002] Dyed veneer is a beautiful and exquisite new decorative material produced by using high-tech processing technology to process defects and color natural veneer. Unavoidable defects such as discoloration and wormholes of natural wood can also be replaced by technology. It is overcome with the help of technology wood and natural wood. It is an effective supplement to natural wood veneer. Because of its smooth surface and rich colors, it leaves room for color imagination for designers and makes people feel The living environment has added a lot of color to meet the requirements of different decoration places and the texture preferences of the majority of buyers. The specific production process of dyed veneer is: select suitable veneer (some veneers cannot be done due to essential problems), and...
