Abstract
The invention discloses a high wear-resistant ultraviolet curing coating, which 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 and 5 to 15 percent of nano-scale silicon dioxide. The nano-scale silicon dioxide grafted on dipentaerythritol hexaacrylate is added into a formula, and the transparency and wear resistance of the ultraviolet curing coating can be well achieved.
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 high abrasion 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, RCA(paper tape wear-resistant index under 20 microns situation) at 600～1000 times/175g, wear resisting property is poor like this, on the exigent product of wear resisting property, such as the frequent part that frequently contacts with human body in the various product component, as the coating that uses on mobile phone button, computor-keyboard, mouse and other the various electronic products, traditional photo-cured coating has been difficult to meet the demands, and therefore providing the superior ultraviolet-curing paint of a kind of wear resisting property is the technology that industry is thirsted for always.
Summary of the invention
The invention provides a kind of high abrasion ultraviolet-curing paint,, can well solve the transparency and the wear resistance of photo-cured coating by in prescription, being added in grafted nanometer grade silica on the double pentaerythritol methacrylate.
The present invention is achieved by the following technical solutions: a kind of high abrasion 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%
Nanometer grade silica 5～15%.
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.
Described nanometer grade silica is meant grafted nanometer grade silica on double pentaerythritol methacrylate.
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.
Because nanometer grade silica is reunited in system easily, disperse inhomogeneously, can influence the transparency and the wear resistance of system, the grafted nanometer grade silica can well solve the transparency and the wear resistance of system on double pentaerythritol methacrylate.Particle diameter ratio traditional material owing to nanometer materials is littler again, like this can be more wear-resisting in friction.
This patent product is through experimental determination, RCA(paper tape wear-resistant index under 20 microns situation) reach 5000 times/more than the 175g, be used on cell phone keyboard, the computor-keyboard and hardly depainting phenomenon can take place.
Embodiment
Below by embodiment the present invention is further elaborated.
The light curing agent product that the various embodiments described above are made carries out RCA(paper tape wear-resistant index under 20 microns situation) test, the test loading is 175g, the result is as follows:
This patent product has very strong wear resistance as can be seen.Those skilled in the art will recognize that; above-mentioned embodiment is exemplary; be in order to make those skilled in the art can better understand this patent content; should not be construed as is restriction to this patent protection domain; change or modify so long as disclose spiritual any being equal to of being done, all fall into this patent protection domain according to this patent.
