Abstract
The invention discloses an ultraviolet curing painting capable of being cured at low energy. The ultraviolet curing painting comprises the following components in percentage by mass: 40 to 60 percent of photosensitive resin, 25 to 45 percent of crosslinking diluent, 2 to 12 percent of photoinitiator, 1 to 8 percent of trimethylolpropane tri-sulfenyl ester, and 0.1 to 0.8 percent of ultraviolet storage stabilizing agent. The painting can be cured under natural light irradiation by adding the trimethylolpropane tri-sulfenyl ester and the ultraviolet storage stabilizing agent without higher energy irradiation.
Description
Technical field
The present invention relates to a kind of UV-light to visible light solidifying material, relate in particular to a kind of can be at low-yield down solidified ultraviolet-curing paint.
Background technology
Photo-cured coating claims photoactive coating again, is the ultraviolet-curing paint that is called of the paint solidification energy with the UV-light.UV-light (UV) is coating material solidified need not to be heated, can be on inflammable grounds such as paper, plastics, leather and timber film-forming rapidly.Ultraviolet-curing paint mainly is made up of photosensitive resin, photosensitizers (light trigger) and thinner, adds some additives simultaneously, as thermo-stabilizer, adds pigment and filler during the preparation colored paint.
Photosensitive resin generally is the low-molecular-weight resin that has unsaturated link(age), as unsaturated polyester, acrylic oligomers; Photosensitizers is easily to absorb the compound that UV-light produces living radical, as benzophenone, st-yrax alkyl ether; The main effect of thinner is to reduce dope viscosity, also participates in film-forming simultaneously, is reactive thinner, as vinylbenzene, acrylate etc.
The photo-cured coating advantage is set time short (part second to several minutes), solidification value is low, volatile matter is low, is to economize the energy, resource-saving, nuisanceless, high efficiency coating new variety; Its shortcoming is that free radical type photo-cured coating solidification process is prevented by oxygen, and surface cure is bad.
Traditional paint solidification is that the method for physical dryness is removed the solvent in the macromolecular solution by heating normally, obtains the hardened paint film.It then is to utilize the energy of UV-light to cause low molecule performed polymer in the coating or oligomer and as polymerization between the monomer molecule of reactive thinner and crosslinking reaction, obtain the paint film that hardens that UV solidifies, and comes down to realize chemical seasoning by forming chemical bond.
People have also found some problems when using ultraviolet-curing paint, for example traditional photo-cured coating will be at 600mj/cm
2-1000 mj/cm
2Could solidify under the intensity, energy consumption is higher like this, and to the requirement of ultraviolet source than higher, thereby make traditional ultraviolet-curing paint to contacting with human body, need can't use under the low-energy environment.For example be applied to the makeup that contain ultraviolet-curing paint on nail or the skin, if need very strong energy to solidify with traditional UV coating, the injury to human body is bigger like this.Therefore a kind of low-yield solidified ultraviolet-curing paint down is provided is the technology that industry is thirsted for always.
Summary of the invention
The invention provides a kind of can be at low-yield down solidified ultraviolet-curing paint, thereby make that by adding trimethylolpropane tris thiol esters and the agent of UV-light storage-stable in prescription the coating of this patent can be promptly curable under natural lighting, need not higher energy exposure.
The present invention is achieved by the following technical solutions: a kind of can be at low-yield down solidified ultraviolet-curing paint, the component and the mass percent of described photo-cured coating are as follows
Photosensitive resin 40～60%
Crosslinked thinner 25～45%
Light trigger 2～12%
Trimethylolpropane tris thiol esters 1～8%
UV-light storage-stable agent 0.1-0.8%.
Further preferably, also comprise in the described photo-cured coating:
Solvent 5～20%.
Further preferably, also comprise in the described photo-cured coating:
Flow agent 0.2～1%.
More preferably, described crosslinked thinner is selected from tripropylene glycol diacrylate, Viscoat 295, pentaerythritol triacrylate, tetramethylol methane tetraacrylate, tetramethylolmethane six acrylate, Hydroxyethyl acrylate, the hydroxyethyl methylacrylate one or more.
More preferably, described light trigger is selected from 2-hydroxy-2-methyl-1-phenyl-1-propyl group ketone, 2,4, in 6-trimethylbenzoyl diphenyl phosphine oxide, 1-hydroxyl-ring ethyl-phenyl ketone, benzoin dimethylether, the benzophenone one or more.
More preferably, described photosensitive resin is selected from aliphatic polyester type polyurethane six acrylate, the aliphatic polyester type polyurethane diacrylate one or both.
More preferably, the agent of described UV-light storage-stable is selected from MEHQ, para hydroxybenzene cresols, the aluminium salt one or more.
More preferably, described flow agent is selected from organic silicon modified by polyether, polyester modification organosilicon, polyacrylic ester, propylene soda acid and holds resin, polydimethylsiloxane, PSI, in the organic radical modified polyorganosiloxane one or more.
More preferably, described solvent is selected from vinyl acetic monomer, N-BUTYL ACETATE, toluene, dimethylbenzene, acetone, the butanone one or more.
The trimethylolpropane tris thiol esters is similar to a kind of initiator, being different from the conventional initiator part is directly to be linked on the resin or the monomeric pair of key, and curing speed is tens even hundred times of conventional initiator, its shortcoming mainly is can be promptly curable under (as natural light) under normal illumination, so there is significantly affecting in its processing transportation, so in this patent, add the agent of UV-light storage-stable, thereby make both performances replenish mutually, make that not only this patent product can be at low-yield down fast setting, and convenient again transportation storage.
This patent product is through experimental determination, at 80～100 mj/cm
2Just can solidify rapidly under the intensity, institute's energy requirement greatly reduces, thereby makes this patent product require low-yield curing field to possess extremely strong technique effect.
