Environmental protection UV coating
Technical field
The present invention relates to a kind of coating, be specifically related to a kind of environmental protection UV coating.
Background technology
UV is coating material solidified is that the new coating kind on the ground such as America and Europe, Japan is popular at twentieth century end.
Being applied to the external coating process of furniture, floor, mobile phone, walkman shell the earliest, its application is existing
Further expand to household appliance technical field and motorcycle and the Lacquer finish etc. such as cosmetics containers, television set and computer
Other field.
UV is exactly the English abbreviation of ultraviolet (Ultra-VioletRay). and industrial UV wavelength is with 200nm
It is its range of application to 450nm.The processing procedure irradiating " UV irradiates hardenable material " with UV and make it harden,
We term it " UVCuringProcess ".Environmental protection UV coating can pass through dip-coating, showering, paint be coated with,
After the method coatings such as spin coating, even vacuum painting, then irradiate and film-forming through UV photons.Gu Mingsi
Justice, the solidification of environmental protection UV coating is inseparable with the irradiation of UV light.This technique functions comes from 70 years
The international coatings market in generation, is a kind of brand-new green technology.Utilize the ultraviolet light polymerization that this technology produces
Coating, is called for short UV coating.In 20 end of the centurys, UV is coating material solidified to come into vogue in the ground such as west, Japan, is
A kind of coating variety representing fashion.It is applied to the earliest at the external coating of mobile phone, DVD, walkman shell
Reason, its application now further expanded to the household appliance technical field such as cosmetics, television set and computer later.
UV photocureable coating has without VOC (VOC), and environmental pollution is little, solidification
Speed is fast, saves the energy, cured product performance is good, be suitable for the advantages such as high-speed automated production.And pass
System coating is volatile, curing rate slow, is unfavorable for environmental protection.Therefore, UV coating is traditional coating
Main substitute.
Compared with general solvent based coating, the feature of UV coating is as follows:
UV coating solidifies (UV quartz burner) under UV photons irradiates, generally only need about 1 second or
Shorter time, can carry out quick and continuous operation, be greatly improved production efficiency.
Conventional oligomer in UV coating, such as epoxy acrylate, urethane acrylate, polyester acrylic
The resins such as ester, polyether acrylate, acroleic acid esterification polyacrylic resin and insatiable hunger polyester, and various
The simple function group of acrylate or polyfunctional monomer, all can be by freely under the effect of UV photons
Base causes polymerized at room temperature and crosslinking, thus be particularly conducive to heat sensitive base material (as timber, paper and
Plastics) covering with paint.
UV coating need not heat drying, thus can save energy when construction than conventional heated drying coating
Source 75%-90%.
The various coating equipments of UV coating are compact, are not required to drying tunnel, simple and efficient to handle, it is easy to accomplish produce
Automation, thus it is greatly saved occupation area of equipment, and reduce working space.
UV coating is solvent-free or the most solvent-free a kind of coating, and in film forming procedure, VOC free evaporate into air
In, environment is not polluted, it is easy to meet the environmental regulation of government or legislative bodies.
UV coating realizes the cross-linked polymeric between component under the effect of UV photons, and liquid is quickly solid
Chemical conversion film, and has tridimensional network, thus coating surface performance can be made to be improved, as hardness,
Pliability, wear-resisting scratch-resisting, chemical proofing, high gloss, durability etc..
