Description
Technical Field
The invention relates to the technical field of light-cured varnish, in particular to novel ultraviolet light-cured varnish capable of being coated on a food container.
Background
The UV light curing coating is a coating which can be quickly dried under the action of Ultraviolet (UV) photons. UV curable coatings have become a relatively mature technology, and particularly, as people's environmental awareness increases, manufacturers and researchers pay more attention to the development and application of UV curable coatings. The UV ultraviolet light curing coating is different from a common solvent-based coating in that no or almost no solvent is volatilized in the film forming process of the UV ultraviolet light curing coating, namely the construction process of converting liquid into solid, so that zero emission or low emission of organic volatile compounds (VOC) is realized, and the UV ultraviolet light curing coating can be called as an environment-friendly coating.
Unsaturated polyester, polyurethane acrylate, epoxy acrylate and the like of common UV curing coating are used as main oligomers, and a proper amount of active diluent and photoinitiator are added, so that the UV curing coating is widely applied to the fields of woodware, plastics, metals, paper, optical fibers and the like. However, in the field of food contact, it has been found that the initiator can migrate chemically after the coating has been cured, and thus cause some damage to the health of the human body.
Disclosure of Invention
In view of the problems identified in the background art, the invention provides a novel ultraviolet light-curable varnish that can be applied to food containers.
The technical scheme of the invention is realized as follows:
the novel ultraviolet curing varnish capable of being coated on a food container is characterized by comprising the following components in percentage by mass: 30-40% of epoxy acrylic resin, 40-50% of monomer, 0.1-1% of defoaming agent, 0.1-2% of dispersing agent, 5-15% of filling agent and 1-5% of photoinitiator.
Preferably, the monomer is at least one of oxydi (methyl-2, 1-ethylene) diacrylate and glycerol trimethylolpropane triacrylate.
Preferably, the filler is at least one of talc, calcium carbonate and silica.
Preferably, the mesh number of the talcum powder is 400 meshes.
The novel ultraviolet curing varnish capable of being coated on a food container further comprises the following operation process steps;
1) the discharge ports, the dispersion rods and the dispersion discs in the stirring kettle and the stirring kettle are wiped clean by alcohol, so that the product is prevented from being polluted;
2) and putting the resin into a dispersion kettle according to the amount, starting stirring at the rotation speed of 1000-.
In conclusion, the beneficial effects of the invention are as follows: the novel ultraviolet curing varnish capable of being coated on the food container can be coated on the food container, and has the characteristics of high hardness, good glossiness, corrosion resistance, good heat resistance, small shrinkage rate, high adhesion, good flexibility and the like after coating, and has no chemical migration after coating.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
the novel ultraviolet curing varnish capable of being coated on a food container comprises, by mass, 40% of epoxy acrylate, 27.3% of glycerol trimethylolpropane triacrylate, 0.2% of an antifoaming agent, 0.5% of a dispersant, 30% of 400-mesh talcum powder and 2% of a photoinitiator (819).
Preferably, the dispersant is a nonionic modified fatty acid derivative.
By adopting the technical scheme, the cured varnish coating has the characteristics of high hardness, good glossiness, corrosion resistance, heat resistance and the like due to the epoxy acrylate resin.
The glycerol trimethylolpropane triacrylate is an active diluent for light sensitivity, can effectively reduce the viscosity of the varnish, improve the curing speed, and has good storage stability, small shrinkage rate of a varnish coating, high adhesive force and good flexibility.
The 400-mesh talcum powder is used for filling the varnish, so that the varnish coating can be conveniently polished.
The dispersant is used to uniformly disperse the varnish coating so that the components in the varnish do not precipitate and agglomerate.
The photoinitiator can rapidly initiate the polymerization and crosslinking of monomers in the varnish, thereby achieving the zero migration of the photoinitiator.
By adopting the technical scheme, the method also comprises the following operation process steps,
1) the discharge ports, the dispersion rods and the dispersion discs in the stirring kettle and the stirring kettle are wiped clean by alcohol, so that the product is prevented from being polluted;
2) and putting the resin into a dispersion kettle according to the amount, starting stirring at the rotation speed of 1000-.
The second embodiment is as follows:
the novel ultraviolet curing varnish capable of being coated on a food container comprises, by mass, 35% of epoxy acrylate, 35.8% of oxydi (methyl-2, 1-ethylene) diacrylate, 15% of glycerol trimethylolpropane triacrylate, 0.2% of an antifoaming agent, 1% of a dispersant, 10% of silicon dioxide and 3% of a photoinitiator (819).
Wherein, the silicon dioxide needs to be processed by wax, so that the varnish coating obtains better hand feeling.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
