Abstract
The invention discloses a mold release paint for pet meat food can inner walls and a preparation method thereof, relating to the technical field of food can packaging paints. The paint is composed of the following components in percentage by mass: 60% of 6009 epoxy resin solution, 15% of 284 phenol formaldehyde resin, 15% of mold release agent and 10% of mixed solvent. The preparation method comprises the following steps: preparing the solid 6009 epoxy resin from 128 epoxy resin and bisphenol A, adding the mixed solvent to prepare the 6009 epoxy resin solution, and finally, adding the 284 phenol formaldehyde resin and mold release agent to prepare the target paint. The paint has the advantages of favorable mold release property, high adhesive force and impact resistance of the coated film, and high safety; and all the technical indexes conform to the food hygienic standard.
Description
Technical field:
The present invention relates to food can package technical field of coatings, be specifically related to a kind of pet meat-based food top tank structure release coating and preparation method thereof.
Background technology:
Along with the raising of people's living standard, the family of pet feeding also increases gradually, and the consumption of pet food can increases fast.And pet meat-based food top tank structure release coating requires height than the canned luncheon meat inner wall release coating that people eat, this is because starch content carnivorous in pet tank is high, easily sticky tank, therefore needs the consumption of increasing releasing agent or uses the better releasing agent of stripping result instead.In addition, because the can body of pet food canned meat is higher than luncheon meat can body, for guaranteeing that can carry out high-temperature sterilization safely, need in the middle part of can body, add several pressure footpaths, this is just to needing the sticking power and the shock resistance that improve film.In addition, can produce a certain amount of volatilization residue when toasting after paint tinplate and pollute drying room, impact print is coated with quality.
Summary of the invention:
Technical problem to be solved by this invention is to provide that a kind of stripping result is good, production cost is low, film adhesive and the strong pet meat-based food top tank structure release coating of shock resistance and preparation method thereof.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A kind of pet meat-based food top tank structure release coating, is made up of the component of following mass percent:
Described releasing agent is modified polypropylene waxes.
Described mixed solvent is made up of pimelinketone, N-BUTYL ACETATE, propyl carbinol, S-100A and ethylene glycol monobutyl ether.
A preparation method for pet meat-based food top tank structure release coating, comprises the steps:
The synthesis of (1) 6009 epoxy resin: add 128 epoxy resin, dihydroxyphenyl propane and catalyzer in proportion in reactor under stirring, mixture is heated to 180 ~ 190 DEG C of reaction 45 ~ 90min, and reaction terminates rear cooling, pulverizes to obtain solid 6009 epoxy resin;
The preparation of (2) 6009 epoxy resin solutions: add solid 6009 epoxy resin and mixed solvent prepared by step (1) under stirring in proportion in reactor, then reflux dewatering 60min, insulation 2h after mixture being heated to 130 DEG C, finally be cooled to 40 DEG C, discharging, filter and obtain 6009 epoxy resin solutions;
(3) synthesis of coating: add 6009 epoxy resin solutions, 284 resol, releasing agent and mixed solvent prepared by step (2) under stirring in proportion in reactor, mixture is fully uniformly mixed under room temperature, finally cools, filters and obtain target coating.
In described step (1), the mass ratio of 128 resins, dihydroxyphenyl propane and catalyzer is 72:27:11, and catalyzer is imidazoles.
In described step (2), the mass ratio of solid 6009 epoxy resin and mixed solvent is 2:3.
In described step (3), the mass ratio of 6009 epoxy resin solutions, resol, releasing agent and mixed solvent is 12:3:3:2.
The adding of macromolecule epoxy resin in coating, contribute to improving film snappiness, improve sticking power and the shock resistance of film, make the coating obtained have good demolding performace, shock resistance, sticking power, erosion resistance.
The invention has the beneficial effects as follows: operation of the present invention is simple, it is low to consume energy, production cost is low; And obtained coating has good release property, stronger film adhesive and shock resistance, and all technical all meets food hygienic standard, and security is high.
Embodiment:
The technique means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the present invention further.
Embodiment 1
A preparation method for pet meat-based food top tank structure release coating, comprises the steps:
The synthesis of (1) 6009 epoxy resin: add 720kg128 epoxy resin, 270kg dihydroxyphenyl propane and 110kg imidazoles in 500L reactor, mixture is heated to 180 ~ 190 DEG C of reaction 45 ~ 90min, after reaction terminates, cool, pulverize to obtain 6009 epoxy resin.
The preparation of (2) 6009 epoxy resin solutions: add 400kg solid 6009 epoxy resin and 600kg mixed solvent in 1000L reactor, reflux dewatering 60min, insulation 2h after mixture being heated to 130 DEG C, after being finally cooled to 40 DEG C, 6009 epoxy resin solutions are filtered and obtain in discharging.
