Description

Crown plug bonds coating and preparation method thereof with high performance PE
Technical field
The present invention relates to bond paint field, more particularly to crown plug high performance PE bonding coating and preparation method thereof.
Background technology
The crown plug of beer or beverage bottle is used for the sealing protective effect of vial, needs bottle cap and body to be held after combining Do not leaked by certain pressure, therefore one layer of elastomeric material, the attachment of this layer of elastomeric material and base material iron are injected in bottle cap domestic demand Power is inadequate, it is therefore desirable to coating is coated on iron-based material, resinous coat is formed after baking paint solidification, the coating is in heating shape Bonding is played under state and plays material layer and the protection rustless effect of iron-based material.Country's elastomeric material used PVC (polychlorostyrene second in the past Alkene) and color stuffing remix the modulation of a large amount of plasticisers and form, the material does not meet recent regulations in foodsafety, now such as The modern elastomeric material is progressively changed to polyolefin (PE) elastomer.
And for example disclose a kind of for beer, the adhesive of beverage crown plug in Chinese patent literature CN201734917U The preparation method of coating and crown plug, described adhesive coating includes epoxy resin, phenolic resin, amino resins, modified poly- second Alkene micro mist wax, auxiliary agent and mixed solvent.Although the document can realize that, by crown plug and PE materials bonding, main rise bonds The modified poly ethylene micro mist wax cohesive force of effect is not strong, is 394N/cm to the maximum2, in use easily cause crown plug and PE materials are separated, and do not have the effect of needs.
The content of the invention
To overcome disadvantages mentioned above, an object of the present invention is to provide a kind of bond effect more preferable crown plug height Performance PE bonds coating, and the second object of the present invention is to provide a kind of crown plug high-performance corresponding with the first purpose PE bonds the preparation method of coating.
In order to reach one of object above, the technical solution adopted by the present invention is：A kind of crown plug is bonded with high performance PE Coating, weight percent note, including following components：Epoxy resin 20-40%, phenolic resin 2-10%, amino resins 1- 5%th, organic solvent 30-60%, catalyst 0.1-2%, polyester resin 2-8%.The present invention is substituted by using polyester resin to be changed Property polyethylene micropowder wax, the polar bond of polyester resin can produce suction-operated with a small amount of polar group in pad so that apply The adhesion strength of material is higher, and bond effect is more preferable.
Preferably, the polyester resin is polyester resin LTH.LTH polyester trees of the invention by using goldschmidt chemical corporation Fat, the molecular weight of polyesters is smaller, and acid number is higher, can increase adhesive force of the film to ground after addition, and enhancing is glued to pad Power is tied, while also add film impact resistance.
Preferably, the epoxy resin is epoxy resin 607.The present invention is by using epoxy resin 607, epoxy resin 607 be bisphenol A type epoxy resin of the epoxide equivalent in 2100-2400g/eq, if low epoxy can cause coating to molecular weight again Pliability is not enough, and the high coating solid of molecular weight can be reduced, and amount of solvent is big, is unfavorable for cost and environmental issue.
Preferably, the phenolic resin may be selected from least one of PR34419, PR612, PR285 or PF6535LB.
Preferably, state amino resins and may be selected from least one of BF892, TD126 or CYMEL659.
Preferably, the organic solvent may be selected from dimethylbenzene, cyclohexanone, propylene glycol monomethyl ether, propylene glycol methyl ether acetate or At least one of ethylene glycol ether acetate.
Preferably, the catalyst may be selected from enclosed type DBSA, two nonyls of closing p-methyl benzenesulfonic acid or closing Base how at least one of sulfonic acid.
In order to reach the two of object above, the technical solution adopted by the present invention is：
A kind of crown plug bonds the preparation method of coating with high performance PE, comprises the following steps：
The first step：The organic solvent of certain mass is added dissolution kettle, the LTH solids of certain mass are added under agitation, Close manhole and open steam heating, maintain 60-70 DEG C of temperature in the kettle 1 hour, be cooled to less than 40 DEG C filterings and release, produce one Determine the LTH solution of quality；
Second step：The organic solvent of certain mass is added another dissolution kettle, the epoxy of certain mass is added under agitation Resin, is warming up to 100-110 DEG C, and maintenance treats that epoxy resin dissolving is complete for 1 hour, and be cooled to less than 50 DEG C it is stand-by；
3rd step：The phenolic resin of certain mass is added in above-mentioned epoxy resin solution, stirring continues to add after 10 minutes Enter the amino resins of certain mass, be stirred for adding whole above-mentioned LTH solution after 10 minutes, stir 10 minutes, add one Determine the catalyst of quality, be stirred for more than 35 minutes sampling detection, it is qualified after filter and package.
Using technical scheme, when the bonding coating is used to be bonded crown plug and PE layers, the present inventor is in surprise It was found that its cohesive force has obtained significant raising, its cohesive force is 573N/cm to the maximum2, than the 394N/cm of prior art2Improve 45%, achieve preferable technique effect.
