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.Be applied to the external coating process of furniture, floor, mobile phone, walkman shell the earliest, its Application Areas now further expands to household appliance technical field and the other fields such as motorcycle and Lacquer finish such as cosmetics containers, televisor and computer.
UV is exactly the English abbreviation of ultraviolet (Ultra-VioletRay). and industrial UV wavelength is its range of application with 200nm to 450nm.Irradiate " UV irradiates hardenable material " with UV and the processing procedure making it harden, we are referred to as " UVCuringProcess ".Environmental protection UV coating is coated with by dip-coating, showering, paint, spin coating, even after the coating of the method such as vacuum painting, then irradiates and film-forming through UV photons.As its name suggests, the solidification of environmental protection UV coating is inseparable with the irradiation of UV light.This technique functions comes from the international coatings market of the seventies, is a kind of brand-new green technology.Utilize the ultraviolet-curing paint that this technology is produced, be 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.Be applied to the external coating process of mobile phone, DVD, walkman shell the earliest, its Application Areas now further expanded to the household appliance technical field such as makeup, televisor and computer afterwards.
UV photo-cured coating has containing volatile organic compounds (VOC), and environmental pollution is little, and curing speed is fast, save the energy, cured product performance good, be suitable for the advantages such as high-speed automated production.And traditional coating is volatile, curing speed slow, be unfavorable for environment protection.Therefore, UV coating is the main substitute of traditional coating.
Compared with general solvent based coating, the feature of UV coating is as follows:
UV coating is solidification (UV quartz burner) under UV photons irradiates, and usually only needs about 1 second or shorter time, can carry out quick and continuous operation, greatly enhance productivity.
Conventional oligopolymer in UV coating, as resins such as epoxy acrylate, urethane acrylate, polyester acrylate, polyether acrylate, acroleic acid esterification polyacrylic resin and insatiable hunger polyester, and the simple function group of various acrylate or polyfunctional monomer, all can under the effect of UV photons, cause polymerized at room temperature by free radical and be cross-linked, thus be particularly conducive to the covering with paint to heat sensitive base material (as timber, paper and plastics).
UV coating does not need heat drying, thus can save energy 75%-90% when constructing than the heated drying coating of routine.
The various coating equipments of UV coating are compact, do not need drying tunnel, simple and efficient to handle, are easy to realize the production automation, thus greatly save occupation area of equipment, and reduce working space.
UV coating is a kind of solvent-free or substantially solvent-free coating, and in film process, VOC free evaporate in air, does not pollute environment, the environmental regulation of be content with very little government or legislative bodies.
UV coating realizes the crosslinking polymerization between component under the effect of UV photons, by liquid fast setting film forming, and there is tridimensional network, coating surface performance thus can be made to improve, as hardness, snappiness, wear-resisting scratch-resisting, chemical proofing, high glossiness, wearing quality etc.
Summary of the invention
For above shortcomings in prior art, technical problem to be solved by this invention is to provide a kind of environmental protection UV coating.
A kind of environmental protection UV coating; comprise the component of following weight parts: tripropylene glycol diacrylate 40-60 part; 2-methyl-2-2-hydroxyethyl acrylate phosphoric acid ester 6-10 part; urethane acrylate 35-45 part; aliphatic urethane acrylate 2-4 part, 2,4; 6-trimethylbenzoyl phenyl phosphinic acid ethyl ester 4-8 part, organosilicon flow agent 0.2-0.4 part.
A kind of environmental protection UV coating; comprise the component of following weight parts: tripropylene glycol diacrylate 40-60 part; 2-methyl-2-2-hydroxyethyl acrylate phosphoric acid ester 6-10 part; urethane acrylate 35-45 part, aliphatic urethane acrylate 2-4 part, 2; 4; 6-trimethylbenzoyl phenyl phosphinic acid ethyl ester 4-8 part, organosilicon flow agent 0.2-0.4 part, sterilant 0.2-0.4 part.
Described sterilant is N-(4,6-dimethyl pyrimidine-2-base) aniline and/or enostroburin.Preferably, described sterilant is mixed by N-(4, the 6-dimethyl pyrimidine-2-base) aniline of 10-30wt% and the enostroburin of 70-90wt%.N-(4,6-dimethyl pyrimidine-2-base) aniline or enostroburin are used for, in coating, serving good effect by the present invention pioneeringly.
Tripropylene glycol diacrylate, also known as tri (propylene glycol) diacrylate, CAS No.:42978-66-5.2-methyl-2-2-hydroxyethyl acrylate phosphoric acid ester, CAS accession number: 52628-03-2.2,4,6-trimethylbenzoyl phenyl phosphinic acid ethyl ester, No. CAS: 84434-11-7.
N-(4,6-dimethyl pyrimidine-2-base) aniline, CAS:53112-28-0.Enostroburin, CAS:238410-11-2.
