Description
Technical field：
The present invention relates to aqueous adhesive technical fields, and in particular to a kind of to prepare water using ultrasonic-microwave collaboration method
Property labeling agent technique.
Background technology：
Label agent, i.e. Commercial goods labels adhesive.Currently, many recyclable commodity packagings are all individually carried out using adhesive
The stickup of label, such as plastic packing product and glass packaging product, in order in recycling quickly into the stripping of row label.
Existing adhesive mainly uses traditional casein cement and aqueous composite adhesives, but both products all have one
Fixed defect.First, traditional casein cement is temperature sensitive, when temperature reduces or increases, the viscosity meeting of casein cement
It is rapidly rising or falling, influences the stability in use of product；And casein cement haves the shortcomings that high speed shear is thinning, in height
The stability of product is poor when fast machine uses, and is easy to splash away from sizing idler wheel, causes the pollution of machine and a large amount of losses.
Secondly, aqueous composite adhesives use a large amount of macromolecular waterproof resins as raw material, although solving the resistance to water problems of label, together
When reduce temperature sensitivity, but since macromolecule resin is insoluble in water, recycled in plastic packing product or glass packaging product
When adhesive residue can not clean up completely, if using cosolvent come remove adhesive residue again exist increase cleaning
The problem of wastewater treatment difficulty.
Invention content：
Technical problem to be solved by the present invention lies in provide that a kind of raw material is easy to get, operation is simple and the feature of environmental protection is strong
The technique for preparing aqueous labeling agent using ultrasonic-microwave collaboration method.
The technical problems to be solved by the invention are realized using technical solution below：
A kind of technique being prepared aqueous labeling agent using ultrasonic-microwave collaboration method, is included the following steps：
(1) pretreatment of gelatin：Edible gelatin is added in the water of 5-10 times of weight, is dispersed with stirring and is uniformly placed on ultrasound
In wave-microwave synergistic extraction instrument, and supersonic frequency 40kHz, ultrasonic power 50W, microwave frequency 2450MHz, microwave power are set
Hydrolysis of polymaleic anhydride is added after 700W, reflow treatment 5-10min, stirs evenly, continues reflow treatment 5-10min, gained is mixed
It closes object and lotion is made through being concentrated under reduced pressure, lotion is sent into after cooled to room temperature in freeze drier, dry obtained solid warp
Particle is made in pulverizer；
(2) chemical modification of cetanol：After cetanol and L-Glutimic acid are mixed plus absolute ethyl alcohol dissolves, then is added dropwise dense
Sulfuric acid regulation solution pH value is heated to reflux state insulated and stirred to 4-5, stops heating after reaction, through being concentrated under reduced pressure
Ethyl alcohol is recycled, condensate residue is dissolved in water completely, and gained mixed liquor is sent into spray dryer, and dry gained particle is through ultra micro
Micro mist is made to get modified cetanol in pulverizer；
(3) preparation of coalescents：It is heated to after food-grade polyglutamic acid and PEG-60 rilanit specials are mixed
105-110 DEG C of insulated and stirred 5-10min, then with the cooling rate of 5 DEG C/min be cooled to 0-5 DEG C heat preservation stand 1-3h to get at
Film auxiliary agent；
(4) preparation of aqueous labeling agent：Gelatin after pretreatment, coalescents and modified cetanol are added to the water,
Stirring and dissolving is complete, and viscosity control is in 1000-3000mPa.s to get aqueous labeling agent.
Edible gelatin in the step (1), hydrolysis of polymaleic anhydride mass ratio be 100:1-10.
Cetanol in the step (2), L-Glutimic acid mass ratio be 10:5-10.
Food-grade polyglutamic acid in the step (3), PEG-60 rilanit specials mass ratio be 5:1-5.
Gelatin after pretreatment in the step (4), coalescents, modified cetanol mass ratio be 100:5-15:
1-10。
Coalescents also include the nanometer rubber powder with PEG-60 rilanit special equivalent, nanometer rubber powder in the step (3)
Preparation method be：Brazil wax is added into polyethylene glycol oxide, and is heated to molten condition insulated and stirred, adds ultra-fine
Nanometer powder is made to get nanometer rubber powder using nano-level grinder while hot after mixing in magnesia.
The polyethylene glycol oxide, Brazil wax, super fine magnesia mass ratio be 1-5:1-5:1-5.
The beneficial effects of the invention are as follows：
(1) present invention is using hydrolysis of polymaleic anhydride as pretreating agent, and cooperates with method significantly to change by ultrasonic-microwave
The cold water-soluble of kind gelatin；Although ultrasonic-microwave collaboration is owned by France in ordinary skill in the art means, it is specifically answered
It uses in the pretreatment of gelatin and the operation for obtaining improvement gelatin cold water-soluble technique effect is not belonging to skill customary in the art
Art means；And although pretreating agent hydrolysis of polymaleic anhydride is in acidity, its with this field routine pretreatment inorganic acid or
The physicochemical property of organic acid is entirely different, and this field does not disclose the technical side using hydrolysis of polymaleic anhydride as pretreating agent
Case, and the common knowledge of this field does not provide the technical inspiration using hydrolysis of polymaleic anhydride as pretreating agent yet；
(2) present invention keeps made modified cetanol soluble easily in water by the chemical modification to cetanol, while utilizing spermaceti
The emulsifiability that alcohol itself has is compatible to promote the blending that labeling agent prepares raw material；And made modified cetanol has certain
Thickening property, to improve it is made labeling agent adhesive force；
(3) present invention by the preparation of coalescents with cooperate with gelatin and modified cetanol improve made labeling agent at
Film properties, so that made labeling agent can quickly form ultra-thin bonding film, the bonding film in labeling between label and commodity
Formation not only can guarantee firm attachment of the label under commodity normal operating condition, but also can guarantee and pass through clear water when commodity recycle
Immersion and backwashing manner can be effectively peeled off trade mark and remove labeling agent, and labeling agent clearance rate is made to reach 99.5% or more；
(4) present invention further increases the use of made labeling agent by the additional addition of nanometer rubber powder in coalescents
