Description
Technical field
The invention discloses a kind of preparation method of trademark adhesive specific complex starch adhesive, belong to binding agent technology of preparing
Field.
Background technology
General requirement to beer bottle label glue is good fluidity, and initial adhesion force is strong, and rate of drying is fast, and properties are stable.
The quality of trademark adhesive not only directly affects the production efficiency of beer, and influences labeling quality.The beer bottle being commonly used
Trademark adhesive species has casein class, plant proteinses, chemical glue, amylan and modified starch adhesive.Though casein class trademark adhesive
Right combination property is fine, but its cost is very high, is suitable only for applying in high-grade beer field.Although plant proteinses trademark adhesive price
It is cheap, but caking property is not strong, poor water resistance, causes to be commonly used.Chemical glue can not meet people due to seriously polluted
Demand.Amylan is using starch as natural adhesive made of base-material.Starch is that green plants is produced by photosynthesis
Natural polymer, so amylan belongs to plant glue.The low in raw material price of amylan and modified starch adhesive, and as a kind of
Renewable resource is increasingly narrowed by the green grass or young crops of people, particularly in recent years the industrial production of adhesive towards inexpensive, nuisanceless
Direction develop, amylum adhesive as natural reproducible adhesive make its many-side be better than other adhesives.Ative starch
Adhesive is due to the needs of combination property, it usually needs formaldehyde is added, so as to have residues of formaldehyde in the product, to environment and people
Cognition causes certain injury, and can deteriorate production environment, and its water resistance, adhesion strength etc. are also not ideal in addition,
So using being subject to certain restrictions.On the research of modified chlorinated starch, artificial synthesized macromolecule is mainly added at present, thus
Complex process and high expensive.
Thus, also need to study amylan, prepare formaldehydeless, green, adhesion strength is good, rate of drying is fast,
The stable novel starch adhesive of properties.
The content of the invention
The present invention solves the technical problem of：For traditional starch glue adhesion strength deficiency, asking not environmentally
A kind of topic, there is provided preparation method of trademark adhesive specific complex starch adhesive.

Step（4）The defoamer is silicone emulsion, appointing in dimethyl silicone polymer or polyoxyethylene oxygen propyl alcohol amidogen ether
Meaning is a kind of.
The beneficial effects of the invention are as follows：
（1）Chitosan is carried out initial breakdown by technical solution of the present invention with enzyme first, makes hydroxyl active in chitosan molecule chain
Exposed with amino, recycle thiocarbamide to be modified chitosan, in modified chitosan molecule structure, contain a large amount of bands
The active group of lone pair electrons（Such as-NH2 ,-C=S etc.）, can occur with the metal ion in the inorganic metal salt that is added in system
Coordination, and under crosslinking agent effect, finally crosslink, the presence of metal ion, be on the one hand advantageous to the cross-linking reaction of system
Carrying out, product cohesive strength is effectively improved, adhesion strength is lifted, and on the other hand, can play antibacterial bacteriostatic effect,
The stability during product use is improved, makes product continue to play gluing characteristic；
（2）Technical solution of the present invention to starch by carrying out ball milling activation, in mechanical milling process, starch crystals plot structure and particle
Pattern is destroyed, and crystallinity is effectively reduced, so that mobility enhancing of the starch after activation in system, makes body
The diffusional resistance of other compositions declines in system, diffuses easily into starch molecule, and Hydrogenbond is formed with the hydroxyl in starch, from
And the cohesive strength of system is further improved, product adhesion strength is further lifted, and the addition of thiocarbamide modification of chitosan, can
The starch molecule after activation is set to be scattered in cross-linked network, collaboration improves product adhesion strength.
