Description
Technical field
The invention belongs to paint field, relate to decorative powder coatings, the special-purpose decorative powder coatings of especially a kind of glass wine bottle and earthenware porcelain receptacle and application.
Background technology
Traditional bottle spraying coating process is by oiliness or water-borne coatings spraying, through high bake clagging at workpiece surface.But there are following defective in oiliness or sofa coating;
At first, the defective of water-borne coatings existence is as follows:
Water-borne coatings requires height to reaching the material surface degree of cleaning in the construction process, and because the surface tension of water is big, dirt easily makes the generation shrinkage cavity of filming; It is poor that water-borne coatings resists the dispersion stabilization of strong mechanicals efforts, makes the generation pit of filming; Utilization ratio is low, and difficulty is recycled, although the water-borne coatings of Li Yonging is not absorbed by water Lian curtain and finally energy hydrolysis, also is pollutent after all; The baking-type water-borne coatings requires strict to construction environment condition (temperature, humidity), increased the input of conditioning equipment, has also increased energy consumption simultaneously; Water-borne coatings evaporation of water latent heat is big, and the baking energy expenditure is big; The organic cosolvents that the water-borne coatings boiling point is high etc. produce a lot of oil smoke when baking, may drip after condensing in film coated surface and influence outward appearance; There is the problem of poor water resistance in water-borne coatings, and the medium of water-borne coatings generally all is slight alkalinity (ph7.5～ph8.5), the ester bond facile hydrolysis in the resin and make molecular chain degradation, the performance that influence is filmed.
Simultaneously, the harm of paint is bigger: contain volume benzene or toluene, dimethylbenzene in its thinner (lacquer thinner), the long-term organic solvent steam that sucks, can cause aplastic anemia so that leukemia, this brings potential safety hazard for the application employee, has also brought unfavorable factor for drinks, slurry class, the can based food hygienic safety of splendid attire.
Powder coating then has a clear superiority in, and it does not contain solvent, and very utilization ratio has been stopped the contaminate environment phenomenon.Can realize full-automatic totally-enclosed application, stop harm employee health event and taken place, save cost of labor simultaneously.Coating is smooth glossy, and is graceful noble, promotes product quality, and creative arts is enjoyed.Powder coating is applied in fields such as food, medicine, medicine equipment for a long time, but because glass and pottery are not charged, therefore is difficult to realize electrostatic spraying.
By retrieval, do not find the patent publication us relevant with patent application of the present invention as yet.
Summary of the invention
The objective of the invention is to overcome the weak point of liquid application techniques, a kind of characteristics such as high-decoration, ethanol-tolerant, high temperature resistant low temperature, energy-saving and environmental protection that have are provided, the special-purpose decorative powder coatings of the glass wine bottle of solvent-free, nontoxic pest and earthenware porcelain receptacle, this coating is desirable paint and the substitute of water-borne coatings aspect the bottle application.
The technical solution adopted for the present invention to solve the technical problems is:
The special-purpose decorative powder coatings of a kind of glass wine bottle and earthenware porcelain receptacle, its raw material constitutes component and parts by weight are respectively:
And described extraordinary resin is food grade Resins, epoxy.
And described food grade Resins, epoxy is the diphenylol propane glycidyl ether.
And described extraordinary solidifying agent is pharmaceutical grade imidazoles or phenols curing agent.
And described pigment is made up of superfine titanium white and mineral dye, titanium dioxide: the part by weight of mineral dye is 50:4 ~ 6.
And described filler is the pharmaceutical grade precipitated super-fine barium sulfate.
And described auxiliary agent is the mixture of flow agent, anti-interference agent and pore eliminator, flow agent: anti-interference agent: the weight ratio of pore eliminator is: 16 ~ 22:10 ~ 20:4 ~ 8 part.
And the mixture of described flow agent, anti-interference agent and pore eliminator is 788 flow agents, 701B anti-interference agent, benzoic mixture, 788 flow agents: 701B anti-interference agent: benzoic part by weight is 9:7:3.
The application of aforesaid powder coating aspect glass decoration.
Advantage and positively effect that the present invention obtains are:
1, powder coating of the present invention adopts the specific epoxy resin, has improved ethanol-tolerant solvent borne and glass attachment power performance; Adopt extraordinary solidifying agent, with the modified imidazole catalytic curing in the hope of reaching the target of fast setting and relatively low temperature-curable, characteristics and the difficult problem of glass non-refractory have been overcome, make uncharged glass and pottery also can realize application smoothly, an antipollution difficult problem when having improved curing is simultaneously simplified pretreatment procedure, has replaced former oil spout lacquer or water-borne coatings technology, do not have any pollution and nuisance and produce energy-conserving and environment-protective.
2, powder coating of the present invention has long flexible chain, has fabulous intermiscibility, the reactive behavior height, very strong adhesive power is arranged, but fast setting, the cross-linking density height, film have remarkable rigidity and humidity resistance, chemical-resistant, solvent resistance, excellent scratch resistance performance, high-decoration; Effect, Smooth and moist glittering and translucent as enamel after the application, suitable drinks refrigerates and stores sth. in a cellar.
3, the selected pigment of powder coating of the present invention, filler component are: titanium dioxide, carbon black, iron oxide yellow etc., be the common raw material of food and pharmaceutical industries, there is not the safety and sanitation problem, this coating only is used for decorative appearance, do not contact with inner splendid attire thing, but detect with coating hygienic standard GB/T5009.69-2008 by state food yet; And this powder coating has changed the pollution problem of liquid coating, and has passed through the detection of food and medicine inspection and quarantine department, by detections such as the ROHS of European Union, SGS, FDA, the not direct and Food Contact of formed coating can relievedly be used to the greatest extent, has improved the safety and sanitation rank.
4, the selected filler of powder coating of the present invention is precipitated super-fine barium sulfate 100 ~ 300, and is significant to the surface hardness that improves coating, and each material is easily obtained, and cost is low, but does not reduce every performance of filming; The solidifying agent that adopts is for adopting pharmaceutical grade tetrahydroglyoxaline or phenols curing agent, makes that coating can the low temperature fast setting and have heavy anti-corrosion function, to improve film flexibility, the sticking power of increase base material; The pigment that adopts is made up of mineral dyes such as titanium dioxide, carbon blacks, and the difference of its parts by weight of different colours is bigger, but does not influence the performance of coating, and is only relevant with color.
