Description
Technical field
The invention belongs to food material field, more particularly to a kind of packaging for foodstuff coating material and preparation method thereof.
Background technology
In paint field, by addition additive to improve material character, such as：Silver is added and is used as antiseptic, or is added
Zinc oxide is as fungicide.
Plastic film has been widely adopted as packaging material for food, and typical thin films have：Polyethylene (PE), low-density are poly-
Ethylene (LDPE), polypropylene (PP), Biaxially oriented polypropylene (OPP), polystyrene (PS), gathers high density polyethylene (HDPE) (HDPE)
Vinyl chloride (PVC), polyvinylidene chloride (PVDC), poly-vinegar (PET), nylon (NY) are answered by what the above different materials were combined
Close film.But the conjugation between existing plastic film material and coating material is relatively low, be easy to cause and falls off.
Invention content
For above-mentioned demand, invention especially provides a kind of packaging for foodstuff coating materials and preparation method thereof.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of packaging for foodstuff coating material, the packaging for foodstuff coating material include：Component A, component B and component C；
The component A is made of the component comprising following parts by weight：
50-70 parts of bisphenol A type epoxy resin,
15-22 parts of tetrafluoroethene and propylene copolymer,
0.8-1.7 parts of selenomethionine,
0.02-1 parts of 2,4,6- trimethyl benzoyl diphenyl base phosphine oxides；
The component B is 10-15 parts by weight, and the component B is made by following methods：Weigh hydroxymethyl cellulose 20-25 weight
Part, 3- glycidyl ether oxypropyltriethoxysilane 5-10 parts by weight, 2-butyl-2-ethyl-1,3-propanediol 12-18 weights
It is anti-at 110-130 DEG C under confined condition, inert gas atmosphere to measure part and methyl diphenylene diisocyanate 0.2-0.5 parts by weight
It answers 3-6 hours, obtains component B；
The component C is treated chitosan 5-10 parts by weight.
The component A further includes acetylbutyrylcellulose 0-2 parts by weight.
The mass ratio of the tetrafluoroethene and the propylene is 1:2-4.
The specific preparation method of the component C is：Bis- (pinacol combined) two boron and second will be slowly added in chitosan successively
Sour ammonium mixes 1 hour, filters, drying.
The mass ratio of the chitosan, bis- (pinacol combined) two boron and the ammonium acetate is 10:0.05-0.8:1-4.
A kind of preparation method of packaging for foodstuff coating material, this approach includes the following steps：
（1）Weigh bisphenol A type epoxy resin 50-70 parts by weight, tetrafluoroethene and propylene copolymer 15-22 parts by weight, seleno egg
Propylhomoserin 0.8-1.7 parts by weight, 2,4,6- trimethyl benzoyl diphenyl base phosphine oxide 0.02-1 parts by weight and acetate butyrate fiber
Plain 0-2 parts by weight；
（2）Component B 10-15 parts by weight and component C 5-10 parts by weight are added to be uniformly mixed in emulsifying mixer, in 80-110
At DEG C, stirs 1-3 hours, obtain the packaging for foodstuff coating material.
The component B is made by following methods：Weigh hydroxymethyl cellulose 20-25 parts by weight, 3- glycidol ether oxygroups
Propyl-triethoxysilicane 5-10 parts by weight, 2-butyl-2-ethyl-1,3-propanediol 12-18 parts by weight and diphenyl methane two
Isocyanates 0.2-0.5 parts by weight are reacted 3-6 hours under confined condition, inert gas atmosphere at 110-130 DEG C, and component is obtained
B。
The mass ratio of the tetrafluoroethene and the propylene is 1:2-4.
The specific preparation method of the component C is：Bis- (pinacol combined) two boron and second will be slowly added in chitosan successively
Sour ammonium.
The mass ratio of the chitosan, bis- (pinacol combined) two boron and the ammonium acetate is 10:0.05-0.8:1-4.
Compared with prior art, the present invention advantage is：
1. the packaging for foodstuff coating material of the present invention is due to containing bisphenol A type epoxy resin, propylene copolymer, seleno egg ammonia
Acid, chitosan, bis- (pinacol combined) two boron, 2,4,6-trimethylbenzoyldiphenylphosphine oxide make material have good
Stability and certain antibiotic property.
2. the packaging for foodstuff coating material of the present invention is due to by by hydroxymethyl cellulose, 3- glycidol ethers oxygroup third
After ethyl triethoxy silicane alkane, 2- butyl -2- ethyls -1,3-PD and methyl diphenylene diisocyanate are handled, it is added
