Abstract
The invention discloses a non-poisonous coating for an inner wall of a food container. The non-poisonous coating is prepared by mixing epoxy resin, modified epoxy resin, a pigment filler, a curing agent, auxiliaries and the like. The non-poisonous coating for the inner wall of the food container does not contain any organic solvents, and has the characteristics of zero poison, zero odor, good adhesion, excellent medium resistance and the like; the sanitary property conforms to the sanitary standard of coating for the inner wall of the food container and the stipulation of Measures for Supervision and Administration of Drinking Water Sanitation, corrosion prevention can last for 20 years or above, and the non-poisonous coating for the inner wall of the food container can also be widely applied to inner wall corrosion prevention of food brewing, petrochemical engineering, seawater desalination projects, shipbuilding, long-distance water delivery and distribution pipes and urban drinking water facilities.
Description
Technical field
The present invention relates to paint field, be specifically related to a kind of for Container inner wall coating.
Background technology
Drinking food product is the solvent that a kind of corrosivity is stronger, the especially corrosion to its container such as beverage, flavoring agent, drinks
Property relatively big, the requirement to food containers corrosion resistance is higher.Therefore, for preventing the drinking food product corrosion to food containers inwall,
And the harmful substance in food containers migrates in food, usually the inwall painting last layer at some food containers is acidproof, resistance to
Oily, alkaline-resisting anticorrosive coating.Along with the expansion of the food safety range of definition, the hygienic requirements of Container inner wall coating is
Cause various countries' extensive concern.China allows that the Container inner wall coating of use has at present: epoxy coating, Vinylidene Chloride are coated with
Material and laccol coating etc..Superchlorinated polyvinyl chloride resin contains Vinyl Chloride Monomer, and vinyl chloride is a kind of carcinogenic toxic compounds, after film forming
Perchlorethylene paint in still may be containing the residual of vinyl chloride.Laccol coating has certain anaphylaxis to human body, its film one
Road film forming is relatively thin, and this type of coating is seldom used.At present, domestic and international Container inner wall coating mostly uses epoxy
Cold coating, but such coating uses organic solvent mostly, along with the increasingly stringent of environmental regulation, the application of solvent based coating by
Gradually it is restricted.
Summary of the invention
Present invention aim at, it is provided that a kind of for food containers inwall non-toxic coatings, the technology used in the present invention side
Case is: a kind of for food inwall non-toxic coatings, it is characterised in that to be mixed with by weight percentage by following components and form:
Epoxy resin 30-50 part
Modified epoxy 10-20 part
Color stuffing 20-40 part
Firming agent 10-25 part
Auxiliary agent 1-5 part.
Further, described color stuffing includes titanium dioxide, silicon powder, barite, aqua oxidation iron oxide red.
Further, described firming agent is modified amine curing agent.
Further, described auxiliary agent includes wetting agent, defoamer, thixotropic agent.
The present invention provides the benefit that relative to prior art: the present invention for food containers inwall non-toxic coatings, no
Containing any organic solvent, having the features such as nonpoisonous and tasteless, adhesive force good, medium-resistance is excellent, sanitation performance meets food and holds
The sanitary standard of device inner-wall paint and the regulation of " Drinking Water Hygiene Surveillance management method ", and its anticorrosion time limit was up to 20 years
Above, it is possible to be widely used in diet brewage, petrochemical industry, Seawater Desalination Project, shipbuilding and distance water-supply pipeline and city
The inner wall anti-corrosive protection of city's facilities for drinking water.
Detailed description of the invention
Below with reference to embodiment, the design of the present invention and the technique effect of generation are clearly and completely described, with
It is completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is the part enforcement of the present invention
Example rather than all embodiment, based on embodiments of the invention, those skilled in the art is not before paying creative work
Put other embodiments obtained, belong to the scope of protection of the invention.
Embodiment 1: a kind of for food inwall non-toxic coatings, it is characterised in that the most mixed by following components
Conjunction is prepared from:
Epoxy resin 35 parts
Modified epoxy 12 parts
Color stuffing 38 parts
13 parts of firming agent
Auxiliary agent 2 parts.
Embodiment 2: a kind of for food inwall non-toxic coatings, it is characterised in that the most mixed by following components
Conjunction is prepared from:
Epoxy resin 40 parts
Modified epoxy 12 parts
Titanium dioxide 12 parts
Silicon powder 5 parts
9 parts of barite
Aqua oxidation iron oxide red 3 parts
Modified amine curing agent 16 parts
Defoamer 0.5 part
Wetting agent 2 parts
Thixotropic agent 0.5 part.
Above the better embodiment of the present invention is illustrated, but the invention is not limited to described enforcement
Example, those of ordinary skill in the art also can make all equivalent modifications on the premise of spirit of the present invention or replace
Changing, modification or the replacement of these equivalents are all contained in the application claim limited range.
Claims (4)
