Staining liquid capable of rapidly changing color and preparation method of staining liquid

Abstract

The invention relates to a staining liquid capable of rapidly changing color and a preparation method thereof. The staining liquid comprises the following components: 50% of metal complex dye with a concentration of 30%, 30% of an emulsifier, 5% of an accelerant (cyanided tallow amine polyoxyethylene ether), 5% of a penetrant (dimethyl sulfoxide) and 10% of ethanol. The staining liquid has the beneficial effects that the staining agent has the effect of being directly soaked without heating and pressurizing; meanwhile, the composite dyeing liquid can be recycled, is good in transparency, good in light resistance and uniform in dyeing effect, retains good wood texture feeling, is fixed to wood wool fibers, has no adverse effect on subsequent processes (such as high-temperature long-time boiling and dry gluing) after dyeing, does not change color or fade after being dried at high temperature, and has good color fastness. The dyed recombined wood wool does not affect subsequent processing such as coating and gluing, so that the multifunctional modernization requirements of wood processing are met, the utilization value of fast-growing willow (bamboo) wood is comprehensively improved, and the staining liquid is widely applied to the fields of high-grade furniture, building materials, high-grade floors, wood carvings, car decoration plates and the like.

Description

technical field [0001] The invention discloses a dyeing solution for rapid color change and a preparation method thereof, belonging to the technical field of dyeing solutions. Background technique [0002] The dyeing solution is a mixture of metal complex dyes and related additives. It is an environmentally friendly dye that does not contain heavy metals and polycyclic aromatic amines, and contains zero formaldehyde and other pollution sources. [0003] Dyeing is to improve the visual properties of wood, but the existing dyed products need to be dyed under high temperature and pressure during wood processing, and the diffusion is uneven, the coloring and light fastness are poor, and they are easy to fade at high temperature. The technical problem to be solved by the present invention is to provide a high-efficiency dyeing solution that can quickly and evenly diffuse and color in recombined wood at room temperature, does not fade after long-term cooking at high temperature, a...
