Description
Technical field
The present invention relates to a kind of anti-stick colored aqueous transfer coating and preparation method thereof, in particular it relates to a kind of with excellent
Heat resistance and the anti-stick of solvent resistance spend vacuum aluminum-coated transfer coatings and preparation method thereof.
Background technology
Vacuum aluminum-coated transfer coatings (hereinafter referred to as " transfer coatings ") obtain in packaging industry particularly cigarette pack industry
It is widely applied, and has gradually been permeated to the luxury foods such as chocolate packaging, cosmetic package and commodity packaging field.Mesh
The transfer coatings overwhelming majority that preceding in the market uses is solvent-based system, largely using esters such as ethyl acetate, butyl acetate, butanone
Ketones solvent, some even also use the larger organic solvent of the toxicity such as toluene, dimethylbenzene, are caused to producing with use environment
Serious pollution, also jeopardizes the health of correlated crowd, has not met the base that modern industry develops to environmentally friendly direction
This requirement.
As in October, 2014 coating consumption tax etc. advocates a series of appearance that coatings industry develops to environmentally friendly direction policies,
The hot focus in market comes on using aqueous transfer coating direction of the water as main dispersing medium, with obvious environment-friendly advantage.State
The resin to aqueous transfer coating such as interior patent CN1293157C, CN101407654A, CN103866613A, CN104513574A
Type selecting and its preparation propose solution from different angles.
However, with the progressively popularization that aqueous transfer coating is applied, " viscous flower " problem turns into puzzlement aqueous transfer coating and existed
Some products, the major issue especially commonly promoted on transfer product." viscous flower " also referred to as " embossing ", " loss of gloss ", refers to
Transfer aluminum plated paper is storing the surface loss of gloss occurred during placement under the conditions of certain ambient temperature and humidity, gravity pressure, general coloured silk etc.
Phenomenon, especially easily occur in the season of summer and autumn two.It is domestic at present there is not yet related is special due to the particularity of " viscous flower " problem
Profit report.
The content of the invention
For in the prior art the defects of, it is an object of the invention to provide a kind of anti-stick colored aqueous transfer coating and its preparation
Method, " viscous flower " problem that general aqueous transfer coating easily occurs in the season of summer and autumn two is overcome, improves aqueous transfer coating
Performance and application.
The present invention is achieved by the following technical solutions：
The invention provides a kind of anti-stick colored aqueous transfer coating, the coating includes following components and parts by weight content：
Preferably, the waterborne polyurethane resin is the organic-silicon-modified aliphatic polyurethane of anionic, and softening temperature is
150~260 DEG C.The softening temperature of waterborne polyurethane resin is too low easily to be occurred turning white when vacuum aluminum-coated and evaporation effect difference etc.
Problem.
Preferably, the waterborne silicone-acrylate resin is organic silicon modified aqueous acrylic resin, glass transition temperature is 50 DEG C~
80 DEG C, average grain diameter is 1~100nm.The too low heatproof of waterborne silicone-acrylate resin glass transition temperature is too poor, too high, and film forming can become
Difference；Particle diameter, which crosses conference, causes film-formation result to be deteriorated.
Preferably, the water-based vinyl chloride-vinyl acetate resin glass transition temperature is 60 DEG C~90 DEG C, and average grain diameter is 1~400nm, such as day
The Vinybran 900 of this day letter.The excessive film forming that is easily caused of the particle diameter of water-based vinyl chloride-vinyl acetate resin is turned white.
Preferably, the coalescents are in alkoxide coalescents, alcohol ethers coalescents, alcohol ether esters coalescents
One or more.
Preferably, other auxiliary agents include the one or more in levelling agent, anti scuffing agent, defoamer；The levelling
Agent is the one or more in Siloxane-Oxyalkylene Copolymers, esters of acrylic acid levelling agent；The anti scuffing auxiliary agent is polyether-modified
Polysiloxanes；The defoamer is the one or more in alkynes alcohol defoaming agent or modified polyorganosiloxane class defoamer.
The present invention has found easily occur the water-based of " viscous flower " problem when being used alone by the compounding of three kinds of water-base resins
3 kinds of polyurethane, waterborne silicone-acrylate resin, water-based vinyl chloride-vinyl acetate resin resins, under certain conditions of mixture ratios, particularly preferred aqueous polyurethane
It is organic silicon modified aqueous acrylic resin for the organic-silicon-modified aliphatic polyurethane of anionic, waterborne silicone-acrylate resin, can be with
Significantly improve its anti-stick colored effect, this may mutually intert between three, limit free volume between macromolecular chain, from
And form that structure is more fine and close, the more preferable film layer of hardness is relevant.
Present invention also offers a kind of preparation method of anti-stick colored aqueous transfer coating, comprise the following steps：
A1, waterborne polyurethane resin, waterborne silicone-acrylate resin, water-based vinyl chloride-vinyl acetate resin be placed in reactor and stirred；
A2, coalescents and deionized water premixed liquid are added in reactor again, stirred；
A3, other auxiliary agents are added in reactor again, stirred；
A4, filtered, packed after step A3 stirs.
Preferably, in step A1, the stir speed (S.S.) is 100~200rpm, and mixing time is 5~10min；Step A2
In, the stir speed (S.S.) is 100~200rpm, and mixing time is 10~15min；In step A3, the stir speed (S.S.) be 300~
500rpm, mixing time are 20~30min.
Preferably, the filtering uses 300 mesh filter screens.
Compared with prior art, the present invention has following beneficial effect：
1) the effective prior art that overcomes of the present invention is easily gone out (using standard aqueous transfer coatings production transfer aluminum plated paper)
The problem of existing " viscous flower ", and then solve this problem and transfer aluminum plated paper is produced and got ready the goods the serious puzzlement brought, contribute to
The lifting of transfer aluminum plated paper product quality.
2) vacuum aluminum-coated transfer coatings provided by the invention also have excellent heat resistance and solvent resistance, have well
Combination property.
3) present invention uses water-base resin system completely, has responded green main trend, has solved painting from source
Volatile organic matter VOCs pollutes the problem of environment in material.
