Description
Technical field
The present invention relates to a kind of UV coating, more particularly to a kind of multi-functional UV coating.
Background technology
UV is exactly ultraviolet (Ultra-Violet Ray) English abbreviation.Industrial UV wavelength is with 200nm to 400nm
For its application.It is hardened with UV to irradiate " UV irradiates hardenable material ".UV coating can by dip-coating, showering,
After the methods of paint applies, spin coating, or even vacuum applies coating, then the film-forming through UV photons irradiation.As its name suggests, UV coating
Solidification be with UV light irradiation it is inseparable.The coating material solidified international coatings markets originating from the seventies of UV, it is a kind of brand-new
Green technology.The ultraviolet-curing paint produced using the technology, abbreviation UV coating.20 end of the centurys, the coating material solidified beginnings of UV
The ground such as west, Japan are popular in, are a kind of coating varieties for representing fashion.UV it is coating material solidified earliest be applied to mobile phone, DVD, with
Body listens the external coating of shell to handle, and its later application field now further expands to the family expenses such as cosmetics, television set and computer
Appliance field.
UV photocureable coating, which has, is free of VOC (VOC), and environmental pollution is small, and curing rate is fast, section
Save the energy, cured product performance is good, is suitable for the advantages that high-speed automated production.And traditional coating is volatile, curing rate is slow,
It is unfavorable for environmental protection.Therefore, UV coating is the main substitute of traditional coating.
UV coating because application field is different and composition is different, but it forms and can be summarized as substantially：
1. reactive diluent, main function is the solid constituent in dissolving U V coating, regulation system viscosity.In UV coating
Diluent is not the volatile organic solvent that general coating uses, but directly participating in film-forming process has respond
Non-volatility solvent.Reactive diluent is for chemical constitution, and usually molecular weight is little and intramolecular contains polymerizable functionalities
A kind of monomer of group, turn into a part for paint film after film forming.
2. oligomer, also have and claim oligomer or oligomer, be the basic framework in UV coating, in the effect of UV photons
It is lower to form the paint film with stereochemical structure, and the various characteristics of paint film are assigned, for example (,) it is hardness, pliability, adhesive force, gloss, resistance to
The performances such as aging.
3. light trigger, it is the key components in UV coating, it is fast its role is to transmit the energy of UV photons
Speed triggers the cross-linked polymeric of monomer and oligomer, the solid transfer process of liquid of promotion system.According to triggering mechanism, light trigger can divide
For two big type of free radical and cation.
4. auxiliary agent, as the term suggests it is to meet specifically used some complementary groups for requiring, improving that paint film property adds
Point, such as levelling agent, defoamer, base material lubricant, delustering agent, dispersant, stabilizer, surface slip agent.These auxiliary agents with it is molten
The conventional use of auxiliary agent of formulation coating is different without what.
UV photocureable coating have no or low VOC emission, save the energy, curing rate is fast, production efficiency is high, sets and flowing water
Line production, solidification temperature is low, is adapted to that production line balance, solidification temperature are low, are adapted to coating heat-sensitive substrate material etc..
But current UV coating also has many problems, for example long-term UV easily turns yellow according to lower, antibiotic property is poor,
Antistatic property is low etc., it is therefore necessary to studies a kind of multi-functional UV coating to gather multi -function in integral whole.
The content of the invention
The invention aims to overcome the deficiencies in the prior art, there is provided a kind of multi-functional UV coating.
Technical scheme is as follows：
