Liquid, modified polyolefin hydrocarbon emulsion after mixing, add in ethyl alcohol, water, ethylene glycol, propylene glycol mixture；Add in auxiliary agent and thickening
Agent is cured after stirring；The solid content of product is detected, and the solid content is adjusted to theoretical value, stirring discharging.It but should
The heat-seal adhesive prepared in patent has：1. hydrolytic resistance is poor；2. the poor adhesive force with aluminium；3. the deficiencies of diluting easily demulsification with alcohol；
4. it is sealed when not having high-speed sealing without leakage, the effect without burnt fine wrinkle mark.
Invention content
For the defects in the prior art, the object of the present invention is to provide one kind to be used for drug blister package high speed medicine-packaging machine
High temperature heat-resistant sealing and preparation method thereof.
The purpose of the present invention is achieved through the following technical solutions：
The present invention provides one kind for drug blister package high speed medicine-packaging machine high temperature heat-resistant sealing, including following quality percentage
Than each component of content：
For above-mentioned raw materials used mass content range：
If the content of modified polyolefin resin is higher than 39.9%, cost is higher；If less than 20%, glue-line intensity is relatively low；
If the content of modified epoxy can influence strength of coating higher than 20%, and can make the weatherability, ageing-resistant of coating
It is less able；And if less than 10%, the high temperature resistance of glue-line cannot be significantly improved；
If the content of auxiliary agent can reduce the intensity of coating higher than 0.5%；And less than 0.1%, then overfoaming is apparent, and levelling becomes
Difference is unfavorable for producing.
Preferably, the modified polyolefin resin is selected from maleic anhydride modified polyolefin, carboxyl acid modified polyethylene, EVA, gathers
One or more of vinyl alcohol, Carboxy, vinyl chloride-vinyl acetate resin.It is outstanding to metal under the conditions of above-mentioned improved polyalkene low-temperature heat-sealing
It is that aluminium has superior adhesion, also there is excellent adhesion to PVC；During high temperature heat seal, above-mentioned modified polyolefin resin can
Fully softening, it is more preferable with the adhesion of base material, it can be sealed to avoid the leakage occurred when sealing or insecure.
Preferably, the modified epoxy is selected from polyether modified epoxy resin, modifying epoxy resin by organosilicon, acrylic acid
At least one of modified epoxy.The epoxy resin of above-mentioned several modifications is with adhesive force is good, chemicals-resistant is outstanding, corrosion resistant
The features such as corrosion is outstanding.The high temperature resistance of coating can be improved, xanthochromia and coke during high temperature heat seal is avoided to wrinkle.
Preferably, the solvent is selected from one or more of butanone, ethyl acetate, n-propyl acetate, n-butyl acetate.
Preferably, the auxiliary agent includes at least one of levelling agent and antifoaming agent.
Preferably, the levelling agent is organosilicon levelling agent.With heat-resisting quantity, when use, can improve adhesive force, reduce
Or eliminate shrinkage cavity caused by due to base material.
Preferably, the antifoaming agent is polyethers antifoaming agent.Polyethers antifoaming agent is with the suds time is long, effect is good, disappears
Steep the features such as speed is fast, thermal stability is good.
There are certain synergistic effect between above-mentioned modified polyolefin resin, modified epoxy and organosilicon levelling agent,
Heatproof and the attachment with base material aluminium can be improved, so that heat-seal adhesive obtained has nothing when high temperature and high speed seals packet medicine
Leakage envelope, without burnt fine wrinkle mark the advantages that.
The present invention also provides a kind of preparation method for drug blister package high speed medicine-packaging machine high temperature heat-resistant sealing, including
Following steps：
S1, it will be stirred and evenly mixed in solvent input reaction kettle, sequentially add modified polyolefin resin, modified epoxy under stiring
Resin stirs 1-2 hours, obtains mixed liquor；
S2, auxiliary agent is added in the mixed liquor of step S1, high-speed stirred 0.5-1 hours, after mixing, shuts down curing
10-12 hours；
S3, solid content is measured, and adjusted to theoretical value；It is stirred for 1-2 hours, cooling, filtering.
Present invention the reason of using above-mentioned preparation process for：It, should be first fully molten since modified polyolefin resin is solid-like
After solution is complete, liquid modifying epoxy resin is added, auxiliary agent should after mixing be added in above-mentioned solution, and be improved after having fed intake
Mixing speed makes it be uniformly dispersed.If each component is added in mixing simultaneously, conglomeration and attached wall are generally resulted in.
Compared with prior art, the present invention has following advantageous effect：
1st, when medicine-packaging machine high temperature and high speed seals, no leakage envelope, without burnt fine wrinkle mark, free from extraneous odour.
2nd, heat seal strength is high, meets product demand.
3rd, glue-line stability is good, and it is unchanged that coated film places 1 year intensity.
4th, it is applied widely, matrix resin content can be formulated by change in wider range and adjust heat seal strength, so as to
Suitable for different Al foil substrates.
5th, the adhesive force with aluminium is improved by modified polyolefin resin and part of auxiliary in the present invention, modified epoxy changes
Kind anti-hydrolytic performance and high temperature resistance, and the present invention, based on oiliness heat-seal adhesive, demulsification caused by there is no being diluted with alcohol is asked
