Alkyd resin and soluble polyurethane acrylate are as basic link stuff in this programme, and can promote each group
Divide film forming adhered to one another, improve the brightness of ink.Carboxymethyl cellulose improves ink viscosity, while can increase between each component
Solubility property, each component mixing it is more uniform.Monoethanolamine can be used for the pH of regulation ink, and can also adjust alkyd resin
Or the acidity of soluble polyurethane acrylate.There is certain consolidating to contain in alkyd resin or soluble polyurethane acrylate
Amount, can produce bubble, organic silicon defoamer is added in water-based ink, reduce the surface tension of water-based ink when preparing ink,
Reduce the generation of bubble.In order that water-based ink printing more uniform ground, adds dispersant and levelling agent in the feed.
Further, the solid content of alkyd resin is 40-50%, viscosity 0.3-0.4Pas.
Preferably, alkyd resin is using soya-bean oil modified alkyd resin, modification of flax oil alkyd resin or the modified alcohol of Chinese catalpa oil
One kind in acid resin.
Using soya-bean oil modified alkyd resin, modification of flax oil alkyd resin or Chinese catalpa oil-modified alkyd resin, improve water-based
The adhesive force of ink, and accelerate drying time.In addition, the solid content of alkyd resin is adjusted to 40-50%, in order to avoid produce more
Bubble.
Further, levelling agent is modified polyacrylate compound.
Modified polyacrylate compound has preferable film forming, and with preferable water-fast unfading, improves
The water resistance of ink.
Further, the viscosity of soluble polyurethane acrylate is 20000-25000mPas.

Property and adhesive property.
Another object of the present invention is to provide a kind of preparation method of water-based ink, it has reduction air bubble content, stirred
Mix the characteristics of uniform.
The above-mentioned purpose of the present invention is achieved by the following technical programs：A kind of preparation method of water-based ink, according to
Following method is made：
Carboxymethyl cellulose is mixed to form cmc soln with deionized water；
It is stirred to form pre-composition under alkyd resin, soluble polyurethane acrylate and pigment vacuum, mixing speed is
100-120r/min；
Pre-composition mixes with cmc soln, monoethanolamine, organic silicon defoamer, dispersant and levelling agent, is made water-based
Ink.
Preferably, the mixing speed of water-based ink is 85-100r/min.
Using above technical scheme, previously prepared cmc soln, alkyd resin, soluble polyurethane acrylic acid
Ester and pigment stir under vacuo, are de-gassed, and are stirred under 100-120r/min speed, and water-based ink can either divide
Dissipate uniformly, the dissolved gas in water-based ink can also be reduced.In advance plus pigment mixing, the color adjustment of water-based ink are uniform.
When pre-composition is mixed with other components, rotating speed is reduced to 85-100r/min, promotes scattered between each component.
In summary, the invention has the advantages that：
1st, soluble air bubble content is less in water-based ink produced by the present invention, using alkyd resin and soluble polyurethane propylene
Acid esters is mixed, and as the solvent of water-based ink, the degree of cross linking of water-based ink is adjusted；Alkyd resin and water-soluble poly
Urethane acrylate adjusts the solid content and pH value of water-based ink in the presence of ammonium acetate, reduces the bubble of water-based ink；
2nd, water-based ink produced by the present invention has preferable adhesion property, and alkyd resin, soluble polyurethane acrylate exist
Viscosity of water-based ink is improved in the presence of ammonium acetate, in addition, also adding carboxymethyl cellulose in water-based ink, further increases alkyd
The degree of cross linking of resin and soluble polyurethane acrylate, the dispersive property of each component in water-based ink can also be improved, improved
The uniformity of water-based ink；
3rd, water-based ink produced by the present invention has preferable water resistance, adjusts alkyd resin and soluble polyurethane acrylic acid
The ratio of ester, its solid content is adjusted, and reduce the water imbibition of water-based ink；In addition, carboxylic first is additionally added in the component of water-based ink
Base cellulose, ammonium acetate and dispersant, further improve the water resistance of water-based ink.
