Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of water-based gloss oil and preparation method thereof, be intended to solve existing polyurethane products and contain toxic substance, problem not environmentally.
Technical scheme of the present invention is as follows:
A kind of water-based gloss oil, wherein, described water-based gloss oil, according to weight percent meter, composed of the following components:
Waterborne polyurethane resin 50 ~ 64.8%
Defoamer 0.2 ~ 0.5%
Water-borne acrylic resin 5 ~ 10%
Water-borne wax emulsion 5 ~ 10%
Solvent 25 ~ 35%.
Described water-based gloss oil, wherein, described solvent is one or both in ethanol, pure water.
Described water-based gloss oil, wherein, in described water-based gloss oil, the moiety of solvent is as follows:
Ethanol 5%
Pure water 20 ~ 30%.
A preparation method for water-based gloss oil as above, wherein, comprises the following steps:
Drop into waterborne polyurethane resin, water-borne acrylic resin, water-borne wax emulsion, moderate-speed mixer; Add ethanol, water, defoamer, middle stirring at low speed, to evenly, is filtered.
The preparation method of described water-based gloss oil, wherein, the process of described moderate-speed mixer is 20-40 minute; The process of described middle stirring at low speed is 10-20 minute.
Beneficial effect: the major ingredient of water-based gloss oil provided by the present invention is aqueous substance, can not work the mischief to human body.As the eco-friendly product of one, this water-based gloss oil not only can give coating good flexility, also can meet the application of high-grade packaging industry by extraordinary texture simultaneously.Intaglio printing press prints, and speed is improved significantly (80 ms/min) and energy is dry rapidly; Printing adaptability is good, there will not be scraper to scrape unclean phenomenon, has ensured quality product; Good operability, by common ink printing operation, operative employee is without the need to Special Training; Printing surface handle effect power can regulate arbitrarily according to customer demand.
Embodiment
The invention provides a kind of water-based gloss oil and preparation method thereof, for making object of the present invention, technical scheme and effect clearly, clearly, the present invention is described in more detail below.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
A kind of water-based gloss oil provided by the present invention, it is the high-quality hydronasty gloss oil of a kind of gravure, described water-based gloss oil mainly adopt a kind of not containing or less containing the waterborne polyurethane resin of N-Methyl pyrrolidone, the gloss oil with strong high texture effect allocated with the material such as other water-base resins.This water-based gloss oil has soft sense of touch and good eliminate optical property, and completely not containing Organic chemical solvents human body being had to harm, this product is not also containing alkylphenol compounds simultaneously, can meet existing market to the requirement of packaging class and environmental requirement.
Particularly, water-based gloss oil provided by the present invention, according to weight percent meter, composed of the following components:
Waterborne polyurethane resin 50 ~ 64.8%
Defoamer 0.2 ~ 0.5%
Water-borne acrylic resin 5 ~ 10%
Water-borne wax emulsion 5 ~ 10%
Solvent 25 ~ 35%.
Wherein, described solvent is one or both in ethanol, pure water.Preferably, described solvent is made up of ethanol and pure water, according to weight percent meter, containing following component in described water-based gloss oil:
Ethanol 5%
Pure water 20 ~ 30%.
Wherein, described aqueous polyurethane is a kind of no-solvent polyurethane based on aliphatic isocyanates and polyether Glycols, is specially adapted to the investment precoat of low gloss.Urethane resin used in the prior art is generally containing the N-Methyl pyrrolidone (N-Methyl-Pyrolidone) to harm, even also contain alkylphenol compounds (such material can cause human endocrine disorder) in some product, aqueous polyurethane of the present invention then reduces as much as possible or does not contain these objectionable impuritiess.Significant soft sense of touch effect is mainly provided at formula.Sense of touch effect is strong and weak to be realized by the content of adjustment in formula, is the main component in formula, the sense of touch effect that content is just not relevant very little.
Because of the water containing high level in resin and formula, stir in production and a large amount of foams can be produced in printing whipping process, therefore, in the present invention's formula, adding defoamer, play the effect of froth breaking.The used in amounts of defoamer is moderate, and content very little, print by the not good impact of defoaming effect; Content too affects flow leveling, and in the present invention's formula, consumption is that 0.2 ~ 0.5% effect is best.
Described water-borne acrylic resin plays the effect increasing sticking power in formula.Very little, sticking power is not good for content, and content is too high affects sense of touch effect, and in the present invention's formula, consumption 5 ~ 10% effect is best.
Described water-borne wax emulsion plays the effect increasing wear-resisting and scratch resistance in formula.Content Tai Gaotai is sliding, impact effect, and in the present invention's formula, consumption is that 5 ~ 10% effects are best.
Described solvent adjusts viscosity as thinner, wherein, solvent adopt ethanol also make each component compatibility in formula better and improve rate of drying.
In the present invention, also provide the preparation method of described water-based gloss oil, it comprises the steps:
Clear inspection production unit, cleans up; Drop into waterborne polyurethane resin, water-borne acrylic resin, water-borne wax emulsion, middling speed (1200-1500 rev/min) stirs 20-40 minute, add ethanol, water, defoamer, middle low speed (800-1200 rev/min) stirs 10-20 minute to evenly, filters and packages.
The major ingredient of water-based gloss oil provided by the present invention is aqueous substance, can not work the mischief to human body.As the eco-friendly product of one, this water-based gloss oil not only can give coating good flexility, also can meet the application of high-grade packaging industry by extraordinary texture simultaneously.Adopt this aqueous nature photosensitive oil packaging product can meet the demand trend of current packaging field to coating environmental protection, safety.Intaglio printing press prints, and speed is improved significantly (80 ms/min) and energy is dry rapidly; Printing adaptability is good, there will not be scraper to scrape unclean phenomenon, has ensured quality product; Good operability, by common ink printing operation, operative employee is without the need to Special Training; Printing surface handle effect power can regulate arbitrarily according to customer demand.This water-based gloss oil product is mainly used in high-end packaging market, and its effect can help coating to produce diverse perception and texture, and more transcendent on quality and performance, environmental protection more.
