A kind of curing of nail polish
Technical field
The invention belongs to make-up technique field, particularly a kind of curing of nail polish.
Background technology
At present, conventional manicure method is: polished by Nail clipper; Then smear oiliness acrylic primer, after natural drying, then smear oiliness acrylic paint colored drawing or applique, natural drying; Finally coat LED ultraviolet-cured paint, natural drying.Natural drying is taken time and is reached tens hours, and, during painted surface solidification, also have a lot of residual solvent to exist in its coating, by the solidification of painted surface, coating residual solvent has no idea to discharge, when climate change, be easy to occur bubble on the surface of paint film, and affect attractive in appearance.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides the curing of fast, the bubble-free nail polish of a kind of curing rate.
For realizing the object of the invention, by the following technical solutions:
A curing for nail polish, comprises the following steps:
1), at nail surface smear background color coating, be heating and curing with near infrared ray;
2), at step 1) gained coating surface smear decorative paint, be heating and curing with near infrared ray;
3), in step 2) gained coating surface smears clear finish, uses LED ultraviolet light polymerization.
As preferably, described background color coating is water paint;
Further preferably, described water paint is water-borne acrylic resin coating.
As preferably, described clear finish is for being Epocryl or polyurethane acrylate resin coating.
As preferably, step 1) near infrared ray heating-up temperature is 50-80 DEG C, keeps 3-6min.
As preferably, step 2) near infrared ray heating-up temperature is 60-80 DEG C, keeps 3-5min.
As preferably, in step 3), UV Light Curing obtains ultraviolet wavelength is 250nm-450nm;
Further preferably, UV cure times is 1-2min.
Advantageous Effects of the present invention is:
1, first the present invention smears one deck background color coating at nail surface, is heating and curing with near infrared ray; Then coat decorative paint, then be heating and curing with near infrared ray; Finally coat clear finish, use LED ultraviolet light polymerization.Wherein background color coating and decorative paint are all heating and curing with near infrared ray, in fact so-called near infrared ray solidification refers to by the nail covered with paint, lacquer, colour wash, etc. and coating thereof under near infrared shining upon, radiation-absorbing energy is also converted to heat energy, thus completing the solidification of coating, near infrared ray solidification has the advantages such as curing rate is fast, intensification is rapid, solidification quality is good.Infrared-ray is utilized to be cured, because near infrared ray has very strong penetrability and heat, skin of paint internal solvent rapid evaporation can be made, drying is carried out finally by LED ultraviolet light polymerization, ultraviolet light polymerization paint film crosslink density is high, and whole solidification process is fast, and gained nail surface coating volume drying is good, good weatherability, film is smooth, bubble-free.
2, further, the present invention's background color coating used adopts water paint, water paint has that price is low, use safety, saving resource and the energy, reduce the advantage such as environmental pollution and public hazards, and in conjunction with the above-mentioned feature utilizing near infrared ray to be cured, it is fast that gained coating has rate of drying, further, with water-repellent paint as finish paint, gained film has the feature of resistance to water, durability.
3, applicant is by a large amount of, and experiment proves, when solidifying background color coating, is 50-80 DEG C by near infrared ray temperature, keeps 3-6min; When solidifying decorative paint, being 60-80 DEG C with near infrared ray, keeping 3-5min; For clear finish, using LED ultraviolet light polymerization, is 250-450nm at ultraviolet wavelength, keeps 1-2min.In such a situa-tion, in process, curing rate is fast, and gained paint film is smooth, bubble-free, particularly when background color coating is water-based, and gained paint film odorlessness.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention will be further described, therefore do not limit the present invention among described scope of embodiments.
embodiment 1
1), at nail surface smear background color coating, smear oiliness acrylic resin paint as background color coating, be heating and curing with near infrared ray, heating-up temperature is 50 DEG C, keeps 6min;
2), at step 1) gained coating surface smear decorative paint, be heating and curing with near infrared ray, heating-up temperature is 60 DEG C, keeps 5min;
3), in step 2) gained coating surface smears transparent UV Epocryl coating as finish paint, and use LED ultraviolet light polymerization, ultraviolet wavelength is 300nm.
Nail surface paint film is smooth, bubble-free, slightly smell.
embodiment 2
1), at nail surface smear background color coating, smear oiliness acrylic resin paint as background color coating, be heating and curing with near infrared ray, heating-up temperature is 80 DEG C, keeps 3min;
2), at step 1) gained coating surface smear decorative paint, be heating and curing with near infrared ray, heating-up temperature is 80 DEG C, keeps 3min;
3), in step 2) gained coating surface smears transparent UV epoxy coating as finish paint, and use LED ultraviolet light polymerization, ultraviolet wavelength is 250nm.
Nail surface paint film is smooth, bubble-free.
embodiment 3
1), at nail surface smear background color coating, smear oiliness acrylic resin paint as background color coating, be heating and curing with near infrared ray, heating-up temperature is 80 DEG C, keeps 3min;
2), at step 1) gained coating surface smear decorative paint, be heating and curing with near infrared ray, heating-up temperature is 80 DEG C, keeps 3min;
3), in step 2) gained coating surface smears transparent UV polyurethane acrylate resin coating as finish paint, and use LED ultraviolet light polymerization, ultraviolet wavelength is 450nm.
Nail surface paint film is smooth, bubble-free.
The present invention replaces common heating with near infrared ray heating, near infrared penetrability and heat energy is utilized to carry out rapid draing, thus make each curing of coatings rapidly and equal no solvent residues, also utilize the characteristic of LED ultra-violet curing wink-dry simultaneously, make that gained film is smooth, bubble-free.
