Abstract
The invention discloses a quick-drying platemaking coating including following components, by weight, 30-40 parts of maleic acid rosin resin, 20-30 parts of acetone, 10-15 parts of dimethylbenzene, 10-15 parts of dipropylene glycol dimethyl ether and 2-5 parts of a dye. The coating is high in surface-drying speed and is excellent in quality.
Description
Technical field
The present invention relates to a kind of quick-drying plate-making coating.
Technical background
In plastic printing plate-making industry, the plate-making technology of current widespread use has electronic engraving, etching plate-making and nearly laser engraving technique obtaining universalness for 2 years at home.Laser engraving technique and etching method are all reacted by acidic etching liquid and copper, make the layers of copper at ink cell place out exposed, recessed ink cell can be obtained after corroding, need before etching unnecessary dew copper part as many engraving patterns adopt acidproof paint to carry out full-filling, in order to the corrosion stoping copper coin to be subject to acidic etching liquid, brushing plate-making coating on copper coin usually.When the solvent evaporates in coating of making a plate is too fast, easily there is shrinkage cavity, advection poor lamp defect in coating; When the solvent evaporates in coating of making a plate is crossed slow, easily there is sagging phenomenon and directly ring time of drying.
Summary of the invention
The technical problem that the present invention solves provides a kind of quick-drying plate-making coating, and surface drying speed is fast and coating quality is good.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of quick-drying plate-making coating, comprises following component and the weight of each component is:
Preferably, in described maleic rosin resin, the addition amount of toxilic acid is 15%.
Preferably, the mass ratio of described acetone, dimethylbenzene and dimethyl ether is 2:1:1.
Preferably, described dyestuff is dispersed black dye.
Preferably, each component mixed by proportioning, through skin grinder grinding, obtained mill base, last latting drown becomes viscosity to be the coating of 16s.
The present invention adopts acetone, dimethylbenzene and dimethyl ether composite as paint solvent, the boiling point of acetone is 56.2 DEG C and belongs to high solvent flashing, the boiling point of dimethylbenzene is 135 ~ 145 DEG C is middle quick-dissolving agent, dimethyl ether boiling point is 175 DEG C and belongs to low speed solvent flashing, three's consistency is good, evaporation rate is reasonable, dissolving power is good, improve the advection of coating, meanwhile, because the evaporation rate of acetone is very fast, film coated surface is diffused into completely, escape, so surface drying speed is fast from fact dry film coated surface again.
Embodiment
A kind of quick-drying plate-making of the present invention coating, comprises following component and the weight of each component is:
Described maleic rosin resin due to be used as this coating membrane-forming agent and for layers of copper protection against corrosion, when meeting product quick-drying performance condition, improve softening temperature to be conducive to ensureing that anticorrosion rete keeps coating stable in 35 ~ 45 DEG C of etching solutions, in described maleic rosin resin, the addition amount of toxilic acid is along with the increase of toxilic acid addition amount, softening temperature improves all gradually, when addition amount 15% for toxilic acid, the softening temperature of maleic rosin resin is the highest, meets the demand that coating film forming is stable.
The boiling point of acetone is 56.2 DEG C and belongs to high solvent flashing, the boiling point of dimethylbenzene is 135 ~ 145 DEG C is middle quick-dissolving agent, dimethyl ether boiling point is 175 DEG C and belongs to low speed solvent flashing, when the mass ratio of acetone, dimethylbenzene and dimethyl ether is 2:1:1, dissolving power and coating better advection, the surface drying time of coating is 4min, because the evaporation rate of acetone is very fast, be diffused into film coated surface completely, then escape, so surface drying speed is fast from fact dry film coated surface.
Described dyestuff is dispersed black dye, and the color of copper electroplating layer is red-purple, and the color of coating forms sharp contrast with it, then easily find to leave over full-filling place or coating quality issues, so be beneficial to Mass Control with blackwash under fluorescent light.Selecting tinting material also to need to consider in this coating of wash-out is carry out in sig water, for reducing the accumulation to elutriant rubbish, selects the tinting material that can be dissolved in elutriant to offer convenience to process management and liquid waste disposal.Comprehensively above-mentioned 2 requirements, select dispersed black dye strong covering power on the one hand, meet above-mentioned requirements on the other hand, its consumption is 2g/L.
A preparation technology for quick-drying plate-making coating, mixes each component by proportioning, and through skin grinder grinding, obtained mill base, last latting drown becomes viscosity to be the coating of 16s.
Claims (5)
1. a quick-drying plate-making coating, is characterized in that: comprise following component and the weight of each component is:
2. a kind of quick-drying plate-making coating according to claim 1, is characterized in that: in described maleic rosin resin, the addition amount of toxilic acid is 15%.
3. a kind of quick-drying plate-making coating according to claim 1, is characterized in that: the mass ratio of described acetone, dimethylbenzene and dimethyl ether is 2:1:1.
4. a kind of quick-drying plate-making coating according to claim 1, is characterized in that: described dyestuff is dispersed black dye.
5. the preparation technology of a kind of quick-drying plate-making coating according to Claims 1-4 any one, is characterized in that: each component mixed by proportioning, and through skin grinder grinding, obtained mill base, last latting drown becomes viscosity to be the coating of 16s.
