Description
Technical field
The present invention relates to printing stand linseed oil of the use in a kind of production that is applied to the mill base that glass, porcelain or ceramic surface decorate and preparation method thereof.
Background technology
The pottery mill base is applied to the decorative porcelain base material, especially is porcelain, pottery or glass surface.Under being used of this mill base, our desired decoration is by traditional decoration technology, and particularly directly printing or indirect printing are applied to ceramic surface, and maturing temperature mostly is 500 ℃ to 1400 ℃ Celsius greatly.This mill base is made of the pigment that can produce inorganic component or colorant usually, also comprises lens layer and printing ink under the situation mostly.Printing ink mainly comprises tackiness agent, solvent and multiple processing subsidiary material.The effect of lens layer is that the pigment that produces inorganic component is fixed on ceramic surface; Tackiness agent and solvent have then formed the printing ink with viscosity, and printing ink is just produced printable slurry with the pigment that produces inorganic component and cover layer.
Known mill base and printing-ink lack good rheological property in printing process.Thixotropic additive, particularly based on the tackiness agent of the component of mixture that contains the conventional adhesive system, mix with liquid solvent or thinner and thixotropic agent selectively, be to be a kind of additive on a kind of or at least part of, it obtains by diisocyanate compound and the reaction of elementary and/or secondary polyamine class, and the use of thixotropic agent has a very important role for the mixture that obtains steady state in having the mill base forming process of high thixotropic.Be applied to solvent that the printing-ink of ceramic mill base comprises for example aromatic hydrocarbon solvent, ethanol, ketones solvent and esters solvent.(see GB 2 245 221 A; DE-OS 25 06 820).
Patent application document (DE-OS 2506820) is described to, and the mill base that the aliphatics by polyacrylamide and glycol person polyglycol, high level and the mixture of aromatics are prepared is also unsatisfactory, because the tack after the printing is bad.These mill bases do not contain tackiness agent, and the blending ratio scope of colorant and printing ink is 1:1 to 7:3, so when requiring mill base when Dicoration base material has good adhesion property, the adhesion effect of mill base can't be satisfactory.
Patent application document (EP 0099471) relates to the use to a kind of screen printing ink, and this printing ink is made of known tackiness agent and additive in the natural wax of 5 microns of particle less thaies and/or the synthetic wax.Tackiness agent and additive can vapor away when being higher than 400 ℃ Celsius fully, do not stay any residue, and in meticulous polychrome printing production process, the temperature of roasting requires Celsius more than 400 ℃ just during with beramic color decorative porcelain or other substrate surface.
Summary of the invention
Technical problem to be solved by this invention is. a kind of thixotropy silk screen printing stand linseed oil, comprise printing-ink, A component and B component, described A component comprises: dimethyl-4.4-diaminodiphenyl-methane, tackiness agent and softening agent, described tackiness agent adopt at least a in glycol ester, ethylene glycol ethyl ether, butyl glycol, n-BMA, butyl methacrylate and the Propenoic acid, 2-methyl, isobutyl ester; Softening agent adopts at least a in dioctyl phthalate (DOP), tributyl acetylcitrate, the dioctyl phthalate (DOP); Described B component comprises: thixotropic agent and diisocyanate compound, described thixotropic agent adopts the hydrogenated castor oil derivative.
Preferably, described tackiness agent is dissolved in aromatic hydrocarbon solvent.
Preferably, the vinylformic acid mass content in the described tackiness agent is 50%.
Preferably, thixotropy silk screen printing stand linseed oil also comprises whiteware pigment.
Preferably, the weight of thixotropic agent account for whole formulation weight 0.05 to 10wt%.
Preferably, the weight of described softening agent accounts for the 5-20wt% of whole formulation weight.
Preferably, the 3-35wt% of the whole formulation weight of described binder constitutes.
Preferably, printing-ink accounts for the 0-5wt% of whole formulation weight.
Preferably, aromatic hydrocarbon solvent adopts aromatics, account for whole formulation weight 50 to 70wt%.
Preferably, and the boiling spread of aromatics be 150 ℃ to 260 ℃.
Target of the present invention provides a kind of thixotropic agent.Known thixotropic agent is the hydrogenated castor oil derivative, but contains thixotropic property and the unstable and very difficult control of the printing-ink of known thixotropic agent.The thixotropic agent that the present invention relates to obtains through behind the mutual chemical reaction by the elementary and/or secondary polyamine class of quantitative proportioning and diisocyanate compound.By changing polyamine and the proportioning of single functional compounds and the total amount of employed diisocyanate compound, provide the thixotropic agent that is applicable to the silk screen printing stand linseed oil.According to embodiment provided by the invention, can produce the thixotropic agent of desired performance.
The present invention also provides a kind of method for preparing thixotropy silk screen printing stand linseed oil, and B component needs slowly to add among the component A, adds while stirring, and the joining day is about 1-3 minute, obtains the thixotropy screen printing ink of transparent quality after 30 minutes to 1 hour.
The invention still further relates to the production process of thixotropy silk screen printing stand linseed oil, particularly a kind of liquid mixture that contains tackiness agent mixes fully with elementary and/or secondary polyamine, next reacts with the diisocyanate class again.Formation by polyurea system produces the thixotroping effect.In any case, can be predetermined the degree of thixotroping by the simple test of carrying out the shadow tone printing at the paper carrier.Quantitative range is the polyamine based on the elementary and/or secondary amine groups of isocyanate groups of about 10-70% equal proportion, and the thixotropy silk screen printing stand linseed oil that obtains has the ceramic ink of high thixotropic, purpose especially according to the invention.
