Description
Technical field
The present invention relates to three pieces beverage can water paint fields, in particular to a kind of no bisphenol A-type three pieces beverage can
Aqueous interior full spray paint and preparation method thereof and spraying method.
Background technique
Principal monomer of the bisphenol-A as synthetic epoxy resin applies in mental package wide along with epoxy coating system
It is general to use the history for having had more than 60 years, until last century the nineties have scientist to have found that bisphenol-A has oestrogen-like hormone successively
Effect, to cause a series of for research of the bisphenol-A to health effect.
To take precautions against food safety risk, European Union, China and the U.S. forbid food packaging of the bisphenol-A for infant in succession.
France promulgates a decree No.2012-1442 in December, 2012, forbids bisphenol-A for all food packagings from 2015.2015
May 11, because its genotoxicity is put into 65 inventory of California, the U.S. also starts to convert without bisphenol-A coating comprehensively bisphenol-A
(BPANI), on 2 14th, 2018 European Union publication regulation (EU) 2018/213 are, it is specified that bis-phenol in food contact varnish, coating
A migration, which must not limit the quantity, surpasses 0.05mg/kg, and requires infant food varnish or coating that must not migrate out bisphenol-A.This regulation
All EU member countries are directly applied for, and were come into effect on September 6th, 2018.It is contemplated that this regulation will continue to accelerate
The European Union even paces without the conversion of bisphenol-A coating in the whole world.
Meanwhile environmental problem, concerning national economy, it is anti-to take a series of measure development atmosphere pollution for China in recent years
It administers the industry dynamic, has fired blue sky defended war.Also actively by installation environmental protection equipment, the emission control of VOC is arrived for mental package industry
It is minimum, while country is also actively promoting the trial of package coating industry using " Water-borne modification " technology, reduces solvent based coating in gold
Belong to the use in packaging.
To meet the needs of market and consumer are to safety packaging, the inner coating for food mental package is also required to meet
Requirement without bisphenol-A.However, most three pieces beverage cans can all repair the existing interior jar applied using interior full spray paint
Protection improves conductivity, further promotes the corrosion resistance of can and the retentivity to content color flavor.It is most at present
Based on solvent type full spray, including vinyl, the products such as epoxy and epoxy acrylic, a small amount of aqueous full spray is also with epoxy third
Based on olefin(e) acid, it is unable to satisfy the requirement without bisphenol-A.
Summary of the invention
In consideration of it, the present invention provides a kind of no aqueous interior full spray paints of bisphenol A-type three pieces beverage can and preparation method thereof
