Abstract
A kind of method for preparing high color fastness veneer layer the present invention relates to ternary built dyestuff and using the dyestuff.Ternary built dyestuff is by biomass nano fiber solubilizer, hindered amine light stabilizer agent and acid bisazo dye according to mass ratio 1：15‑30：100 300 compound.The preparation method of a kind of high color fastness recombinant decorative veneer layer of the present invention, it is characterised in that include the following steps：Using rotary-cut or sliced veneer as primary raw material, logical above-mentioned ternary built dyeing, bionical assembly, environment-friendly toughened glue gluing, gluing, health process are processed into recombinant decorative material flitch, then flitch is made to the recombinant decorative veneer of 0.15 1.0mm of thickness through slicing.The compounding dyestuff of the present invention has good bactericidal and bacteriostatic effect, increases service life, while also have pleasant fragrance, makes dyestuff environmentally protective.
Description
Technical Field
The invention relates to a ternary compound dye and a method for preparing a high-color-fastness veneer layer by using the same, belonging to the technical field of decorative materials.
Background
The recombined decorative veneer (commonly known as a technical wood veneer) is a veneer which is made by using a rotary cut veneer or a sliced veneer as a main raw material, adopting veneer color mixing, lamination and glue synthesis molding to prepare a batten and then slicing. Through years of development, technical wood continuously permeates into various fields of human life from original decorative veneers to floors, composite floors, fireproof plates, various artworks, articles for daily use, cultural and sports articles and the like. However, the close binding property between the dye for dyeing the existing recombined decorative veneer and the wood fiber is poor, the service life is influenced, meanwhile, the environment-friendly property is also poor, and the released toxic and harmful gas is easy to damage the human body.
Disclosure of Invention
The invention aims to overcome the defects in the prior art, and provides a ternary complex dye and a method for preparing a high-color-fastness veneer layer by adopting the ternary complex dye, wherein the ternary complex dye can be tightly combined with wood fibers, the binding force of dye molecules in wood is improved, and the ternary complex dye also has good sterilization and bacteriostasis effects, prolongs the service life and is green and environment-friendly.
The invention aims to realize the following technical scheme, and the ternary compound dye is characterized by comprising a biomass nanofiber solubilizer, a hindered amine light stabilizer and an acid disazo dye in a mass ratio of 1: 15-30: 100-300.
the biomass nano-fiber solubilizer is prepared by adding 1-3 parts by weight of bamboo leaf flavone, 0.5-0.8 part by weight of β -cyclodextrin peppermint oil micro powder and 3-6 parts by weight of nano-particle-size silicon dioxide and/or 2-5 parts by weight of aluminum hydroxide into cellulose colloidal suspension consisting of 4-7 parts by weight of cellulase and 80-150 parts by weight of microcrystalline cellulose, then adding 0.5-1.8 parts by weight of 3-chloro-hydroxypropyl triethyl ammonium chloride, and stirring and reacting at 60-80 ℃ for 18-30 min.
the preparation method of the β -cyclodextrin peppermint oil micro powder comprises the steps of mixing β -cyclodextrin and peppermint oil according to the mass ratio of 8-15: 40-65 at the temperature of 20-30 ℃, and embedding the peppermint oil into an inner cavity of the β -cyclodextrin in a molecular form to form β -cyclodextrin peppermint oil micro powder in an inclusion compound form.
The extraction method of the bamboo leaf flavone comprises the following steps: selecting dry leaves of lower part of bamboo of more than six years old in Dryokohama delavayi, and pulverizing into 0.5-0.8mm folium Bambusae fine powder; dissolving with 75-85 wt% methanol solution, performing ultrasonic treatment for 28-35min, dissolving with 75-85 wt% methanol solution, filtering, and separating by column chromatography.
The acid disazo dye compound is
Wherein,
m1, M2 are independently from each other hydrogen or an alkali metal;
r1 is hydrogen, C1-C4 alkyl or halogen;
r2 is hydrogen;
