Abstract
The invention belongs to paint fields, disclose a kind of antistatic air brushing coating of dumb light, according to parts by weight, raw material are as follows: 20~30 parts of pure-acrylic emulsions, 15~25 parts of styrene-acrylic emulsions, 5~10 parts of polyvinyl alcohol glues, 3~8 parts of dumb light powders, 2~5 parts of antistatic agent solutions, 1~3 part of kaolin, 0.1~0.2 part of dispersing agent, 0.2~0.5 part of brightening agent, 0.2~0.5 part of defoaming agent, 0.5~0.8 part of conductive agent, 0.4~0.6 part of wetting agent and 30~40 parts of deionized waters.The invention also discloses the preparation method of air brushing coating, including antistatic agent solution is prepared, polyvinyl alcohol glue is prepared, prepares air brushing coating.Air brushing coating of the invention has many advantages, such as that wide use scope, antistatic property, printing color are soft gorgeous.
Description
Technical field
The invention belongs to paint field, specifically a kind of antistatic air brushing coating of dumb light and preparation method thereof.
Background technique
Spray-painting printer ink type is broadly divided into aqueous, Weak solvent, solvent, UV.Aqueous printing consumables surface coats water
Property ink-absorbed coated layer, coating is not resistant to water, and cold lamination film need to be covered with again by having sprayed picture surface layer, is used primarily in indoor.Solvent-based inks because
With strong corrosive, it is mainly used in PVC traffic allowance, on PVC lamp box cloth, and contain strong solvent in ink, has injury to human body, by force
Solvent air brushing is gradually substituted.UV type ink adhesive force is good, and three-dimensional sense is strong, is used primarily in glass sliding door, ceramic tile air brushing, plastic foil
The printing of the planes such as material, UV ink is irregular, and UV solidification has not exclusively been easy monomer residue, influences human health.Weak solvent ink
Water is more environmentally-friendly compared to solvent, UV ink, and ink smell is few, and color is ageing-resistant, and the coating waterproof used, can not have to mounting
Film, indoor and outdoor has both use, increasingly by everybody welcome.
Weak solvent product on existing market be mainly Weak solvent PP synthetic paper, Weak solvent PVC film, Weak solvent printing paper,
Weak solvent lamp piece, formulation for coating material mainly include acrylic emulsion, dumb light powder, polyvinyl alcohol, brightening agent, wetting agent and defoaming agent,
It mainly emphasizes the adjustment on color representation and rate of drying after printing, lacks produced when solving practical application from formula
The method of electrostatic problem, such material, which is more than or equal to 50% condition in humidity, can be used normally, but be lower than 50% humidity
Autumn and winter or northern area will affect use, when air brushing, generates serious electrostatic spot, and fuzzy pictures are unclear, lines dislocation, electrostatic
Cause material absorption printing plate not paper feed occur, unreels that place's electrostatic is big, and easy electric shock is hurted sb.'s feelings.Due to propylene in Weak solvent coating
Yogurt liquid is anion systems, it is difficult to the cationic antistatic agent with strong antistatic effect be added, common is to take outer painting
The method of antistatic agent solves Weak solvent product electrostatic problem, but applies antistatic agent outside and need additional increase coating and back tender
Sequence not only increases Operating Complexity, and increases manufacturing cost, while cationic antistatic agent slant acidity, is easy to cause
Coating jaundice is faded.
Summary of the invention
The object of the present invention is to provide a kind of dumb lights, the air brushing coating that antistatic, printing effect is good.
It is a further object of the present invention to provide the preparation methods of the air brushing coating.
One of in order to achieve the above objectives, the invention adopts the following technical scheme:
A kind of antistatic air brushing coating of dumb light, according to parts by weight, raw material are as follows: 20~30 parts of pure-acrylic emulsions, 15~25
Part styrene-acrylic emulsion, 5~10 parts of polyvinyl alcohol glues, 3~8 parts of dumb light powders, 2~5 parts of antistatic agent solutions, 1~3 part of kaolin,
0.1~0.2 part of dispersing agent, 0.2~0.5 part of brightening agent, 0.2~0.5 part of defoaming agent, 0.5~0.8 part of conductive agent, 0.4~0.6
Part wetting agent and 30~40 parts of deionized waters.
Further, the raw material of air brushing coating are as follows: 24 parts of pure-acrylic emulsions, 20 parts of styrene-acrylic emulsions, 8 parts of polyvinyl alcohol glues, 6
Part dumb light powder, 4 parts of antistatic agents, 2.2 parts of kaolin, 0.1 part of dispersing agent, 0.32 part of brightening agent, 0.34 part of defoaming agent, 0.56 part
Conductive agent, 0.48 part of wetting agent and 34 parts of deionized waters.
Further, the partial size of the pure-acrylic emulsion is 0.1~0.2 μm, and minimum film formation temperature is 23 DEG C.
Further, the partial size of the styrene-acrylic emulsion is 0.1~0.2 μm, and glass transition temperature is 14 DEG C.
Pure-acrylic emulsion and styrene-acrylic emulsion are the dedicated blotting lotion of Weak solvent ink, and partial size is at 0.1~0.2 μm, two lotion
Collocation uses, and good to powder covering property, print colors are vivid, and styrene-acrylic emulsion glass transition temperature is 14 DEG C, and film layer bloom is soft
It is tough, excellent substrate adhesion is provided for coating.
Polyvinyl alcohol glue is prepared by polyvinyl alcohol micelle with deionized water, and coating can be improved in alcoholysis degree 99%
Water resistance and film forming, and auxiliary agent is adjusted as the consistency of coating.
Further, the dumb light powder is silica, and average grain diameter is 6.8 μm, and oil factor is 210~260g/100g.
Silica is loose porous, can form dumb light characteristic, and its distinctive hole forms pore effect and is conducive to absorb rapidly
Ink, lines fly ink when reducing air brushing, and coating is made to form venthole, are conducive to the export of electrostatic.
