Abstract
The present invention provides spray paints in a kind of food packaging of no bisphenol-A comprising following components in percentage by weight：Polyester resin 53.8-56.6%；Phenolic resin 6.6-10.8%；Amino resins 4.3-6.6%；Solvent 16.2-18.9%；Auxiliary agent 2.2-3.8%；Pigment 7.5-12.7%.The present invention also provides the preparation methods and spraying method of spray paint in a kind of food packaging of no bisphenol-A.The present invention is required instead of the use of original epoxy resin so as to effectively meet the new food hygiene of no bisphenol-A.
Description
Technical field
The present invention relates to spray paints in a kind of steel drum, in particular to spray paint in a kind of food packaging of no bisphenol-A
And preparation method and spraying method.
Background technique
EU Committee's regulation (EU) 2018/213 is set as the SML limit standard of BPA migration in varnish and coating
0.05mg (food), and formulated minimum SML index when BPA detection, i.e. detection limitation 0.01mg.Above-mentioned these varnish and
Coating may be contacted with following food or article：Babies ' formula milk powder, follow-up formula food, finished cereal preparation with
And other baby foods or special medical purposes food (for the nutritional need for meeting infant, are based on beverage and exclusively for child
The similar products of design).
Thus, this requires the steel drums for having inside courtyard for packing milk powder and infant foods raw material to also comply with this mark
Standard, such as common 200L steel drum.This, which allows for spray paint in steel drum, must not contain bisphenol-A, be wanted with meeting these food hygienes
It asks.However, spray paint is entirely epoxy resin type in steel drum used currently on the market, it is not able to satisfy the new of unparalleled phenol A
Food hygiene requirement.
Summary of the invention
In consideration of it, the present invention provides spray paint and preparation method and spraying method in a kind of food packaging of no bisphenol-A,
The problem of spray paint is entirely epoxy resin type in steel drum used on existing market is aimed to solve the problem that, to meet without bisphenol-A
New food hygiene requirement.
Thus, on the one hand, the present invention provides spray paints in a kind of food packaging of no bisphenol-A comprising following weight
The component of percentage：
Further, spray paint includes following components in percentage by weight in a kind of food packaging of above-mentioned no bisphenol-A：
Polyester resin 54.8-55.6%；Phenolic resin 7.6-9.8%；Amino resins 4.8-6.1%；Solvent 16.7-18.4%；Auxiliary agent
2.7-3.3%；Pigment 9-11.2%.
Further, spray paint includes following components in percentage by weight in a kind of food packaging of above-mentioned no bisphenol-A：
Polyester resin 55-55.4%；Phenolic resin 8.1-9.3%；Amino resins 5.3-5.6%；Solvent 17.2-17.9%；Auxiliary agent
2.9-3.1%；Pigment 9.9-10.3%.
Further, spray paint includes following components in percentage by weight in a kind of food packaging of above-mentioned no bisphenol-A：
Polyester resin 55.2%；Phenolic resin 8.8%；Amino resins 5.4%；Solvent 17.5%；Auxiliary agent 3%；Pigment 10.1%.
Further, above-mentioned pigment includes titanium dioxide and/or iron oxide yellow powder.
Further, the weight ratio of above-mentioned titanium dioxide and iron oxide yellow powder is 1: 1.
On the other hand, the present invention provides the preparation methods of spray paint in a kind of food packaging of no bisphenol-A comprising with
Lower preparation step：
1) according to claim 1 in a kind of food packaging of -6 any no bisphenol-As spray paint proportion, by polyester tree
Rouge, phenolic resin, amino resins and solvent carry out complex treatment；
2) pigment is added in the resulting product of step 1) and carries out decentralized processing；
3) auxiliary agent is added in the resulting product of step 2)；
4) the resulting product of step 2) is filtered, obtains coating.
In another aspect, the present invention provides the spraying method of spray paint in a kind of food packaging of no bisphenol-A, feature exists
In, by a kind of no bisphenol-A food packaging in spray paint be sprayed into steel drum, when spraying, at least 250 DEG C of baking temperature
And it is toasted under at least 8 minutes baking times.
Spray paint and preparation method and spraying method in a kind of food packaging of no bisphenol-A provided by the present invention, phase
It is mainly had the following advantages that compared with the prior art：By using polyester resin and improved proportion is set, instead of original
The use of epoxy resin, so as to effectively meet the new food hygiene requirement of no bisphenol-A.
Specific embodiment
The exemplary embodiment of the disclosure is described in more detail below.Although showing the exemplary implementation of the disclosure
Example, it being understood, however, that may be realized in various forms the disclosure and should not be limited by the embodiments set forth herein.On the contrary,
These embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can communicate completely to the scope of the present disclosure
Those skilled in the art.
The following are spray paints in a kind of food packaging of no bisphenol-A provided in an embodiment of the present invention, specifically answer the coating
In the spraying of inner wall for packing tin for foodstuff such as baby milk tanks, such as common 200L steel drum.
Spray paint is obtained especially by following proportion and preparation method in the poly- food packaging without bisphenol-A, and by with
Lower spraying method sprays (table 1).
Table 1：
Wherein, polyester resin is specifically as follows intermediate molecular weight polyester resin.Solvent and auxiliary agent can be using conventional preparations
The solvent and auxiliary agent of coating, in this not go into detail.Meanwhile above-mentioned pigment can specifically include titanium dioxide and/or iron
Bloom, when using the scheme of titanium dioxide and iron oxide yellow powder, the weight ratio of titanium dioxide and iron oxide yellow powder is specifically as follows 1: 1.
After the various embodiments described above, after the common detection methods detection for bisphenol-A, reach without bisphenol-A
Effect, and using proportion and preparation method thereof and spraying method, so that the coating color after spraying is more beautiful, and without bright
