Cohesiveness between son can suppress hydrone movement wherein, and then effectively suppress moisture turnover coating, reach holding water
Divide the effect of constant and fresh-keeping moisturizing.Additionally, resin is good with mould inhibitor intersolubility so that mould inhibitor is well dispersed in resin,
Mould inhibitor can pass through the cell membrane of microorganism into intracellular and then the elimination of micro-organisms or prevent its germination to prevent mould from giving birth to
It is long, and then reach fresh-keeping effect steady in a long-term.
With reference to Fig. 1, the preparation method of above-mentioned anti-mildew fresh-keeping coating of the invention is comprised the following steps.
Step S110：Raw material is provided, percentage composition by weight includes：It is resin 20%～60%, solvent 30%～70%, anti-
Mould dose 0.5%～10% and auxiliary agent 0.3%～5%.
Step S120：Resin, solvent and auxiliary agent are well mixed, mixed liquor is obtained.
Specifically, the temperature of resin, solvent and auxiliary agent mixing is 30～65 DEG C in step S120.
Specifically, step S120 is comprised the following steps：Resin is dissolved in solvent, is 100～300 revs/min in rotating speed
Under be stirred and heated to 30～65 DEG C；Auxiliary agent is added, continues to stir 30～60min in the case where rotating speed is for 200～400 revs/min, obtained
To mixed liquor.So control temperature and stirring intensity, promote mixed liquor to be well mixed.
Specifically, when mould inhibitor contains natural extract class mould inhibitor, anti-mildew fresh-keeping coating percentage composition by weight is also wrapped
The nertralizer less than 3% is included, step S120 also includes step：Obtain adding the nertralizer to adjust mixed liquor after mixed liquor
PH value be 7～8.The pH that nertralizer adjusts mixed liquor is added to be the acid-base value for control system so that the acid-base value of system
It is close to as far as possible neutral so that the acid-base value of coating is close to neutrality, and then improves its feature of environmental protection.
Step S130：Mixed liquor and mould inhibitor are well mixed, anti-mildew fresh-keeping coating is obtained.
Mixed liquor and mould inhibitor are well mixed so that mould inhibitor is dispersed in inside resin, it is to avoid mould inhibitor is swimming
Amorph is soluble in water when resulting in coating, and the effective content of mould inhibitor declines and then reduces the problem of anti-mold effect.Mould inhibitor leads to
The cell membrane of microorganism is crossed into intracellular and then the elimination of micro-organisms or its germination is prevented to prevent fungus growth, and then is reached
Fresh-keeping effect steady in a long-term.
Preferably, mould inhibitor adds mixed liquor to mix with mixed liquor so that mode is added dropwise, so that mould inhibitor more fully divides
In being dispersed in resin, and avoid mould inhibitor free in a solvent as far as possible, and then improve the effective content of mould inhibitor.More preferably
, it is when mould inhibitor is that natural extract class mould inhibitor and non-natural extract two kinds of species mould inhibitor, two kinds of mould inhibitors are independent
And while drop in mixed liquor, to prevent two kinds of mould inhibitors, successively addition causes the latter's mould inhibitor more to be deposited with free state
In being solvent, causing can not reach preferably with reference to the problem of effect.
Preferably, mixed liquor and the condition of mould inhibitor mixing are 1～2h of mixing at 30～65 DEG C in step S130.Can be with
Understand, mould inhibitor after mould inhibitor completion of dropwise addition, mixed liquor and mould inhibitor is continued to mix 1～2h so that mode plus fashionable is added dropwise.
The stirring mixing in the case where rotating speed is for 500～800 revs/min of step S130.
The preparation method of above-mentioned anti-mildew fresh-keeping coating, process is simple, it is easy to accomplish, the anti-mildew fresh-keeping coating film forming for obtaining
It is good, surface compact, imporous anti-mildew fresh-keeping coating can be formed, it is thus possible to limit the absorption of hydrone and molten to greatest extent
Solution, and the cohesiveness between macromolecule can suppress hydrone movement wherein, and then effectively suppress moisture turnover coating, reach
To the effect for keeping the constant and fresh-keeping moisturizing of moisture.Additionally, mould inhibitor is dispersed in inside resin, it is to avoid mould inhibitor is with free
State there is a problem of soluble in water resulting in mould proof agent content during coating and declining and then reduce anti-mold effect.Mould inhibitor is by micro-
Biological cell membrane is into intracellular and then the elimination of micro-organisms or prevents its germination to prevent fungus growth, and then reaches long-term
Stable fresh-keeping effect.
The anti-mildew fresh-keeping coating is particularly well-suited to that the Storage periods such as fruit, bread and tobacco leaf are shorter, easily go mouldy in short-term and need and
When edible article it is fresh-keeping.
Present invention also offers application of the above-mentioned anti-mildew fresh-keeping coating of an embodiment in anti-mildew fresh-keeping coating is prepared.
It is by the coating of anti-mildew fresh-keeping coating and thermally treated in concrete one embodiment wherein, anti-mildew fresh-keeping coating is obtained.
Above-mentioned anti-mildew fresh-keeping coating is through heat treatment so that resin crosslinks reaction and forms network structure, and mould inhibitor is equal
It is even to be scattered in the network structure of resin, surface compact, imporous anti-mildew fresh-keeping coating are obtained, thus with preferably holding
The constant effect of moisture；Mould inhibitor is dispersed in inside resin, moreover it is possible to effectively prevent from going mouldy, and then reaches preferable fresh-keeping effect
Really.The anti-mildew fresh-keeping coating is particularly well-suited to that the Storage periods such as fruit, bread and tobacco leaf are shorter, easily goes mouldy in short-term and need to eat in time
Article it is fresh-keeping.
Preferably, the condition of heat treatment is to process 5～10s in 80～120 DEG C.Resin crosslinks under this condition reaction
Form fine and close network structure so that coating has the effect for preventing moisture from passing in and out.Due to the finite thickness of coating, heat treatment
Time is oversize will to affect the performance of coating.
Preferably, the condition of heat treatment for successively in 80～85 DEG C, 90～100 DEG C, 105～120 DEG C, 90～100 DEG C and
Process 1～2s at 80～85 DEG C respectively.So coating is heat-treated in the temperature field, the temperature field distribution gradient so that apply
Material film forming early stage gradually heats up, and the film forming later stage gradually lowers the temperature, and then improves the compactness of coating and ensure that coating will not ftracture.More
Preferably, the condition of heat treatment is to process 1.2s respectively at 80 DEG C, 90 DEG C, 120 DEG C, 100 DEG C and 85 DEG C successively.
Preferably, the thickness of anti-mildew fresh-keeping coating is 0.5～10 μm.Then resin can not for the thickness low LCL of anti-mildew fresh-keeping coating
Effective film forming, then the effect of anti-mildew fresh-keeping can not embody.And the thickness of anti-mildew fresh-keeping coating is blocked up, not only cost increases, and
Can not be completely dried in heat treatment, it may appear that return the bad phenomenon such as viscous, and when not being completely dried, due to outer surface part
It is dried, and inside is still into liquid, during continuing to air-dry, is easy to coating occur due to due to internal natural drying to open
Situation about splitting, this also can greatly reduce the effect of anti-mildew fresh-keeping coating.
It is below specific embodiment.
