Description
Technical Field
The invention relates to the technical field of wood coloring, in particular to a water-based wood coloring agent and a coloring method.
Background
Wood color is an important factor in determining consumer impression, and wood and woody materials are colored in order to improve the decorativeness and product value of wood products. In order to realize the efficient utilization of the wood of the artificial forest, inferior wood needs to be improved through a color matching technology to imitate the valuable wood, so that the use value of the wood is improved, and the demand of people on the diversity of wood products is met. The wood color is adjusted, so that the wood has good and designable surface performance, and the utilization rate is obviously improved. However, most wood dyeing auxiliaries are heavy-pollution chemicals, which can cause serious harm to human bodies in the processing and application processes, the physical properties of dyed wood can be reduced sometimes, and the treatment of residual dyeing waste liquid after dyeing cannot be well solved.
The prior wood coloring technology has the problems of uneven wood permeability, poor wood surface coloring effect and the like. When the water content of the aqueous emulsion paint is volatilized, emulsion particles come close to, contact with and stack each other to generate capillary pressure, and the particles are squeezed and interpenetrated to form a coating film. However, the coloring effect is not good because resistance to the rubbing action is gradually generated during the film forming process and the rubbing action is increased with time, which makes the rubbing operation difficult. Although the addition of a delayed drying polymer to the formulation can improve the permeability of the formulation in terms of delayed drying and liquid flow, and improve the surface coloring effect, such as the addition of 2% delayed drying agent to the formulation of dongzhilia et al (coatings industry 2012, 42, 45-48), the drying time of this method is increased, which results in a reduction in the treatment efficiency. In addition, poor dispersion of the aqueous polymer particles and their adhesion to the wood surface also result in poor surface coloration of the wood.
Disclosure of Invention
In order to solve the problems of uneven wood permeability, poor wood surface coloring effect and the like in the existing wood coloring technology, the invention provides the water-based wood colorant which is moderate in viscosity, strong in adhesive force, small in particle size, good in dispersion effect and easy to permeate into wood.
Specifically, the invention provides an aqueous wood colorant, which mainly comprises a pigment, dopamine, nanocellulose and an aqueous polymer resin.
Preferably, in the above aqueous wood colorant, the weight ratio of the pigment, dopamine, nanocellulose and aqueous polymer resin is (40-60): (5-15): (5-10): (10-20), more preferably (45-50): (6-10): (6-8): (15-18).
Research shows that the water-based wood colorant prepared in the proportion range can react with water-based polymer resin and wood fibers to generate high-adhesion resin with proper viscosity; in addition, the nano-cellulose is used as a dispersing agent, so that resin molecules and pigment components can be dispersed in a water solvent, the dispersion is better, the grain size of the colorant is smaller, and the colorant can more easily permeate into the wood.
Further, the nanocellulose is preferably tempo-oxidized nanocellulose, more preferably, it has a size of 100-200 nm.
Further, the aqueous polymer resin is selected from one or more of polyacrylate, polyurethane acrylate and epoxy resin.
Generally, pigments conventional in the art can be used. Further studies have found that inorganic pigments such as carbon black, titanium dioxide, iron oxide yellow or iron oxide red are more suitable for use in the formulation system of the present invention.
Further, the aqueous wood stain of the present invention also includes an appropriate amount of water as a solvent. The amount of water is usually 10-15 times of the total weight of the pigment, dopamine, nanocellulose and aqueous polymer resin.
In some preferred embodiments of the present invention, the aqueous wood stain comprises: 40-60 parts of pigment, 5-15 parts of dopamine, 5-10 parts of nano-cellulose, 10-20 parts of water-based polymer resin and 200 parts of water. More preferably, the aqueous wood stain comprises: 45-50 parts of pigment, 6-10 parts of dopamine, 6-8 parts of nano-cellulose, 15-18 parts of water-based polymer resin and 180 parts of water.
The invention also provides a preparation method of the water-based wood colorant, which comprises the following steps:
1) adding nano-cellulose into water, carrying out ultrasonic oscillation, and fully and uniformly mixing;
2) adding the pigment according to the proportion, and uniformly stirring;
3) adding dopamine and aqueous polymer resin according to the proportion, and uniformly stirring.
The above step 1) is usually carried out at about 65 ℃ and usually by ultrasonic oscillation for 15 to 30 minutes.
The step 2) is usually stirred by a homogenizer, and the stirring time is about 30 minutes when the rotation speed is more than 2000 r/min.
The step 3) is usually performed by stirring for about 1-2h at the rotation speed of 200-300 r/min.
The aqueous wood stain of the present invention is usually used by preparing an aqueous solution having an appropriate concentration (for example, a concentration of about 1 to 5% is common).
The present invention also provides a method of coloring wood comprising:
carrying out plasma pretreatment on the wood before coloring;
the above aqueous wood stain was used for coloring.
Researches find that the wood is subjected to plasma pretreatment before coloring, so that the contact angle of the wood surface can be increased, the hydrophilicity of the wood surface can be improved, and the spreading of a water-based colorant on the wood surface and the wetting of the wood are facilitated; the wood surface also exhibits irregular "irregularities" on the order of microns, which facilitates the adhesion of the resin and better adhesion of the colorant to the wood surface.
For the plasma pretreatment of wood, methods conventional in the art can be employed. For example, plasma gas is sprayed onto the surface of the wood. In the specific embodiment of the invention, a spray gun type DBD is used, working gas He and plasma are generated in the gun and sprayed to the surface of the wood, and the gas speed is 20-30L/min. The power supply is an adjustable high-frequency (10-50kHz) and high-voltage (5-20kV) alternating current power supply. The treatment time is preferably 5-10 min.
For the coloring of wood, a method conventional in the art may be employed. For example, the wood board dimensions are 25mm × 25mm × 5 mm. Preparing the coloring agent into 1-5% aqueous solution, soaking the wood board in the aqueous solution for 10-20 hours, and then air-drying the wood board.
The invention also includes wood prepared by the coloring method.
The aqueous coloring agent is highly appreciated as being nontoxic, odorless and excellent in permeability. Aqueous stains impart longer lasting color than oily stains, penetrate wood, exhibit the aesthetic appeal of the wood itself, and provide protection. The aqueous wood colorant usually uses aqueous resin as main film forming material, such as polyvinyl acetate, ethylene-vinyl acetate copolymer, EVA emulsion, aqueous alkyd emulsion, aqueous epoxy emulsion, aqueous polyurethane emulsion, aqueous acrylic emulsion, etc., dye (pigment) particles and body dye particles in the colorant are bonded together, and the color of the colorant is changed by uniformly coating the colorant on the surface of a substrate or pressing the colorant in wood pores along with the wiping action. Generally, the particle size of the resin, which is usually used as a primer or a sealing primer for wood, is not more than 100nm, so that the deep part of the substrate can be sealed and colored to give a sense of layering.
The aqueous wood colorant provided by the invention adopts dopamine to improve the cohesiveness of aqueous polymer resin and wood, and utilizes nanocellulose to improve the dispersibility of the aqueous polymer resin and wood. The wood coloring method provided by the invention improves the surface roughness of the wood through plasma pretreatment, is beneficial to spreading and wetting of the water-based colorant on the surface of the wood, and simultaneously improves the adhesive force of the colorant on the surface of the wood. The invention solves the problems of uneven wood permeability and poor wood surface coloring effect of the existing wood coloring technology.
