A kind of white ink composition and preparation method for heating elimination
Technical field
The invention belongs to ink area, more particularly to a kind of white ink composition and preparation method for heating elimination.
Background technology
In recent years, to simplify labor intensity, the damage of the raw material of leather, paper and flexible material in shearing is saved
Consumption, it is desirable to be able to basic pattern is drawn in these material surfaces in advance, after cut out and finish, by some physically or chemically
Means, make the ink colors remained above disappear, reach that i.e. picture is write, and carry out printed patterns according to the wish of people or eliminate to scheme
The purpose of case.
At present, in the Patents delivered, Chinese patent CN104497709A discloses a kind of new thermotropic
The preparation method and applications of color ink, but it is mainly used in the field such as food antifalsification label and temperature-sensitive packaging material.China
Patent CN101007916, discloses a kind of color shifting ink, and this color shifting ink can only be within a period of time according to the change of pH value
Discoloration or the effect eliminated are reached, students' supplies is mainly used in.
Above-mentioned technical proposal simply changes color or short time elimination color than better suited, meanwhile, it is to be become using soda acid
Change and eliminate color, it is comparatively laborious in actual application, it is unfavorable for extensive use.Therefore, designing a kind of can forever eliminate
Ink is the major issue for needing to solve.
The content of the invention
The invention aims to overcome the problem of above-mentioned prior art is present, there is provided a kind of white for heating elimination
Ink composite and preparation method thereof.
To achieve the above object, the present invention makes the load of heat discoloration by the way that stearyl alcohol is combined with myristic acid
Body.In case of heating, ink pattern is eliminated, and reaches the purpose that i.e. picture is write.
The present invention realizes that the technical scheme that purpose is used is:
A kind of white ink composition for heating elimination, by mass percentage by component:Mixed solvent is 74-92%,
Mixture of white hard wax is 1-5%, and white solid alcohol is 5-15%, white solid saturated fatty acid 1-5%, and zinc oxide is 0.3%,
High purity aluminium oxide is 0.5%, and titanium oxide is 0.2% composition.
Described mixed solvent is made up of ethanol and ethylene glycol monomethyl ether, and its mixing quality ratio is ethanol:Ethylene glycol monomethyl ether=
1:10.
Described mixture of white hard wax is made up of paraffin and micro mist wax, and its mixing quality ratio is paraffin:Micro mist wax=3:
1。
Described white solid alcohol is that stearyl alcohol is octadecyl alcolol, and its molecular formula is C18H37OH。
Described white solid saturated fatty acid is that myristic acid is tetradecylic acid, and its molecular formula is C13H27COOH。
The particle diameter of described zinc oxide, high purity aluminium oxide and titanium oxide is 0.1-5 μm.
To achieve the above object, another technical scheme of the present invention is:
A kind of preparation method for the white ink composition for heating elimination, comprises the following steps:
1st, mixed solvent and mixture of white hard wax are matched respectively in mass ratio, are well mixed, it is standby;
2nd, the in the mixed solvent stirred in step 1, adds mixture of white hard wax, white solid alcohol and white solid full
And aliphatic acid, 60 DEG C are heated to, after it is completely dissolved, zinc oxide, high purity aluminium oxide and titanium oxide is added, stirs;
3rd, the solution that step 2 is prepared is placed on grinder and is ground to grain diameter for 0.5-15 μm;
4th, the solution that step 3 is prepared is crossed after 600 mesh sieves, packed.
In use, to prevent the solvent in pen core from volatilizing, also need to encapsulate sealer below during filling pen core, it is described
Sealer is the mixture of dimethyl organosilicon and lithium saponify, and its mixing quality ratio is dimethyl organosilicon:Lithium saponify=10:1.
The present invention compared with prior art, has the special feature that and is mainly with beneficial effect:
1st, stearyl alcohol is combined with myristic acid, makes the carrier of heat discoloration.In case of heating, ink figure
Sample is eliminated, and reaches the purpose that i.e. picture is write.
2nd, the ink hot elimination time of the invention can reach 11s.Compared with prior art, increase.
