In, can volatilize gradient according to solvent, in conjunction with practical baking-curing technique, high low boiling point solvent collocation mixing;Low boiling point is molten as a result,
Agent can faster volatilize surface drying, and stream bottle of the coating in baking process can be improved in the high boiling solvents such as dibasic acid ester mixture, protect
The planarization of coating surface is demonstrate,proved, glossiness is improved, ethylene glycol monobutyl ether can drop light oil reservoir surface tension, improve the wetting of coating
Property, coating viscosity stability can be improved in n-butanol.Catalyst in the gloss oil is selected from organotin catalysts or acid catalyst.Tool
For body, coating can be can be improved for being catalyzed isocyanate crosslinking for dibutyl tin or stannous octoate in organotin catalysts
Crosslink density promotes cooking characteristic, while improving coating gloss, and acid catalyst is benzene sulfonic acid type or naphthalene sulfonic acids type, for urging
Change amino resin crosslinked, raising crosslink density, promotes wear-resisting, reduction scratch.Thus, it is possible to which flexible choice is suitable according to actual needs
When catalyst, the performances such as wearability or cooking of Lai Tigao gloss oil.Defoaming agent in the gloss oil can be selected from acrylate
One of class or organosiloxane class.Pass through esters of acrylic acid or the defoaming agent of organosiloxane class, defoaming effect as a result,
It is good, it does not cause coating surface abnormal, does not migrate.Candle agent in the gloss oil can be selected from spherical polytetrafluoroethylmodified modified polyethylene
Wax selects spherical wax, and softening point is high, and deformation is small under high temperature, and smooth degree is excellent, and it is wear-resisting can be obviously improved coating.
As a result, in Laser Jet, priming coat first on cover, after drying, ink layer is printed on priming coat, dry
Glazing oil reservoir again after dry, so that can not puncture the priming coat of the bottom under Laser Jet controlled power, so that food cans boiling
Non-rusting after sterilization or long-term placement, stamp mark is clear, and discrimination is high.
