Description
Technical field
The present invention relates to water paint technical field, particularly relate to a kind of wood artwork with containing super-hydrophobic compound acetate fiber
Water paint of element nanofiber and preparation method thereof.
Background technology
Wood artwork is with all kinds of timber as raw material, through machine or the unique style of home built one class with view and admire
The artware being worth, the most very popular on market at home and abroad, due to wood artwork than conventional wooden utensil in moulding
On the finest, use the time the most permanent, therefore to its surfacecti proteon work have different requirements, at woodenware surface spraying
Paint is relatively conventional preventive means, the paint performance that its surface is used by be directly connected to artware ornamental value and
In service life, due to the particularity of artware, its paint used is not only environment friendly and pollution-free, also to have certain moisture-inhibiting saturating
Gas performance, to ensure that timber is the driest, prevents deformation.Although the aqueous paint emerged in large numbers in the market energy in the feature of environmental protection
Meet demand, but its application on wood substrate and protection effect still have much room for improvement.
Nanofiber is because of properties such as the skin effect of its uniqueness, small-size effect, quantum size effect, optical effects
Being well worth doing in modified paint field, be seen in report at present is concentrated mainly on the inorganic nano-fiber modification to coating, and fine
The report of dimension element nanofiber modified coating is relatively fewer, and cellulose material has cheap and easy to get, ring than mineral-type materials
Protect the advantages such as nontoxic, more for practical value." feasibility of natural fiber micro-/ nano fibril modification coatings for furniture " literary composition research
Show that the key propertys such as the wearability of coating, scratch resistance, pliability are had greatly improved, so by native cellulose nanofibrils
And native cellulose itself easily occurs degradation with aging, reduction of service life under the influence of environmental factors, and then affect coating
Protection effect.
Cellulose acetate is the staple fibre that a class is important, is obtained after hydroxyl acetic acid esterified in cellulosic molecule
Planting the natural high polymer of chemical modification, it is cheap and easy to get, and feel is smooth flexible, has hydrophilic, is suitable as water paint
Modifying agent, the loose structure of its uniqueness can effectively improve the breathability of coating, but single cellulose acetate nanometer
Fibrous mechanical property is poor, in order to improve the serviceability of coating, needs to do further technological improvement.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of wood artwork is with containing super-hydrophobic compound
Water paint of cellulose acetate nanofiber and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of wood artwork water paint containing super-hydrophobic multiple cellulose acetate nanofiber, this water paint is by following weight
Part raw material prepare: solid content is water-borne acrylic resin emulsion 40-50 of 40-50%, cellulose acetate 4-5, fluorine-containing poly-
Siloxanes 0.1-0.2, graphene oxide 0.1-0.2, polyoxyethylene alkyl ether 0.1-0.2, organic silicon defoamer 0.1-0.2, N,
Dinethylformamide 12-15, acetone 35-40, deionized water are appropriate, ammonia 0.01-0.02.
Described a kind of wood artwork preparation side of the water paint containing super-hydrophobic multiple cellulose acetate nanofiber
Method, described preparation method is:
(1) first cellulose acetate, fluorinated polysiloxane, graphene oxide input DMF, acetone are combined molten
In liquid, stirring drips ammonia after being completely dissolved dispersion to it, and is heated to 50-60 DEG C, makes after continuing stirring mixing 30-40min
Becoming solution to carry out electrostatic spinning, spinning condition is: voltage 10-12KV, and receiving range is 15-20cm, and injection speed is 1-
1.5ml/h, reception medium is deionized water, receive medium with 400-500 turn/speed of min do not stops stirring, produce after injection
Thing is centrifugal through washing, the most standby, prepares multiple cellulose acetate nanofiber；
(2) regulation after material step (1) prepared is mixed together uniformly with aqueous acrylic emulsion and other leftover materials
Viscosity, through deaeration, sieve after and get final product.
Water paint of the present invention, based on aqueous acrylic emulsion, with the addition of one wherein and prepared by electrostatic spinning process
Multiple cellulose acetate nanofiber, this composite fibre utilizes fluorinated polysiloxane Dichlorodiphenyl Acetate cellulose to carry out at fluorination
Reason so that it is possess excellent hydrophobicity, the addition of graphene oxide make its simultaneously can in water-based emulsion fine dispersion, in tree
Can form the most ventilative nanofiber layer in fat coating, can be effectively improved the hydro-oleophobicity of coating, surface is smooth bright and clean, easily
In cleaning, practical degree is high.
