Abstract
The present invention relates to ink compounding oil for printing ink, particularly to thixotropic ink compounding oil for printing ink for decals of screen printing. The present invention provides the novel cheaper thixotropic ink compounding oil for printing ink for decals of screen printing, which is both suitable for applique paper with large films and applique paper with small films. The ink compounding oil is formed by adding a thixotropic agent and a diluent agent into film forming substances, wherein the film forming substances are an acrylic ester(co)polymer blend formed by randomly polymerizing four kinds of monomers such as methyl methacrylate, ethyl acrylate, butyl acrylate and butyl methacrylate. Use results indicate that the ink compounding oil of the present invention has good printing adaptability, screen lines and screen points can be clearly reduced, and screens can not be blocked. The adhesive force of an ink layer is good, and colors are firm and can not shed easily. A decoration baking effect is good, and colors are brilliant.
Description
The invention relates to stand linseed oil, particularly about a kind of invention of thixotropic ink oil for screen printed applique paper.
People have passed by and have printed to a long historical process of modernized silk screen printing from Freehandhand-drawing, spraying decoration, stamp the trailing of pottery, enamel, glass etc.The method of utilizing the modern typography to decorate implements has directly and indirect two kinds.So-called decorative method indirectly is earlier pattern to be printed on paper or the plastic film, it is attached to during use on the implements that need to decorate again.Print afterwards earlier and paste, the origin of Here it is transfer paste marble paper.Because meticulous true to nature, easy to use more flexible than the pattern that prints on implements in printing on the paper substrate, so industry such as pottery generally all adopts transfer paste marble paper decorative method.
At present, the decal paper that uses at ceramic industry roughly has two classes: big film marble paper (the polyvinyl butyral acetal marble paper is called for short the P.V.B marble paper) and membranelle marble paper (moving colored film marble paper).The characteristics of big film marble paper are that applique is convenient, cheap.But no matter the printing ink that import or homemade thixotropic ink oil are made, the easy explosion of ink film comes off after the easy adhesion of big film marble paper of printing, the long storage.The clear 62-334250 of Japanese Patent discloses a kind of transfer paste marble paper thixotropy ink adhesive resin combination, only be applicable to the membranelle marble paper by its stand linseed oil of making, and price is more expensive.
The object of the present invention is to provide a kind of new thixotropic ink oil for screen printed applique paper, can be used for the membranelle marble paper and can be used for big film marble paper again.
Another object of the present invention is: under the prerequisite that ensures printability and burning till property, make every effort to reduce the cost of stand linseed oil.
Printing ink is a kind of stable colloidal dispersion system, and its host is by forming as the pigment of disperse phase with as the stand linseed oil of external phase.Stand linseed oil is the dispersion medium in the printing ink host, is the carrier of pigment particles.The printability of printing ink and the property relationship of stand linseed oil are very close.That is to say that the ink performance beyond the color is subjected to the domination of stand linseed oil.The performance of stand linseed oil is then relevant with its formation.
In order to reach purpose of the present invention, at first having researched and developed with methyl methacrylate, ethyl propenoate, butyl acrylate and four kinds of monomers of butyl methacrylate is raw material, with the benzoyl peroxide is initiator, under 90 ℃ of conditions, carry out solution method random copolymerization, obtain a kind of mixture that contains multiple acrylate copolymer.Then based on this mixture, add thixotropic agent, thinner, the elaborate combination prescription has modulated a kind of thixotropic ink oil for screen printed applique paper.Transfer China ink to go up the machine print result through applique paper plant and show, stand linseed oil of the present invention not only is applicable to big film marble paper but also is applicable to the membranelle marble paper that printability, anti-stick page or leaf property, anti-deciduous and burning till property are all good.
Stand linseed oil of the present invention is made up of aforesaid propylene acid ester copolymer 100 weight parts, thixotropic agent 10～30 weight parts and thinner 200～250 weight parts.
Adding thixotropic agent is in order to make the printing ink of making have thixotropy, to adapt to the requirement of silk screen printing.All in principle can give thixotropic Wax can be as thixotropic agent.What the present invention used is synthetic wax.
The used thinner of the present invention is the mixture of n-Butyl lactate, turps, Terpineol 350, white oil of camphor composition.Its consumption is as the criterion with viscosity and the TI value that satisfies stand linseed oil.This thinner is more cheap than a large amount of formula systems of naphthane that use.
The viscosity of thixotropic ink oil of the present invention (25 ℃) is 1.90～5.50Pas; It is 2.50～3.50 that thixotropy is estimated the TI value.
So-called thixotropy is estimated the TI value and is meant: under 25 ℃ of conditions, record the viscosity number η under 90 rev/mins respectively
90With 360 rev/mins under viscosity number η
360Ratio, promptly thixotropy is estimated TI value=η
90/ η
360
The advantage that the present invention is had compared to existing technology is:
1. stand linseed oil of the present invention not only had been applicable to big film marble paper but also had been applicable to the silk screen printing of membranelle marble paper.These two kinds of marble papers can both be used for the decoration of high-grade ceramic.
2. compare with the import stand linseed oil, cheap.
3. solved the problem that the easy adhesion of big film marble paper, the easy explosion of ink film come off, membranelle marble paper quality and external product are suitable.
4. modulation printing ink can be directly used in, and in printing process, thinner need be do not added, easy to use, help the production scene quality control.
Relevant producer uses the back consistently to think in batches: stand linseed oil printability of the present invention is good, and figure line, site reduction are clear, not network blocking.China ink layer sticking power is good, the color fast difficult drop-off, and decoration firing is effective, bright in color.Needn't mix thinning oil during use, be convenient to the production scene quality control.
The invention will be further described below by embodiment.Because esters of acrylic acid can be with the arbitrary proportion copolymerization, so the restriction of 4 kinds of monomer ratios that the present invention is not provided.
