Abstract
The invention discloses a low gloss ultraviolet curing coating, and the ultraviolet curing coating comprises the following components by weight: 5-20 parts of modified bisphenol A epoxy diacrylate, 5-15 parts of polyurethane acrylic resin, 5-15 parts of a tri-functionality activated monomer, 5-15 parts of a mono-functionality activated monomer, 5-15 parts of organic extinction powder, 2-10 parts of MINEX-7, 2-10 parts of a light initiator agent and 0.1-2 parts of an assistant. The low gloss ultraviolet curing coating uses the bisphenol A epoxy diacrylate easy to extinct and modify and the matte polyester acrylate as main body resin, and an alcohol-aldehyde condensation compound of special organic extinction powder urea and the MINEX-7 with extinction characteristics are mixed into the resin to obtain the low gloss ultraviolet curing coating with good matte effects and liquidity and strong extinction effect, so that the low gloss effect of the coating surface is realized.
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 ultraviolet-curing paint of low gloss.
Background technology
Photo-cured coating claims again photoactive coating, the ultraviolet-curing paint that is called taking UV-light as the paint solidification energy.UV-light (UV) is coating material solidified does not need heating, can be on the inflammable grounds such as paper, plastics, leather and timber film-forming rapidly.Ultraviolet-curing paint is mainly made up of photosensitive resin, photosensitizers (light trigger) and thinner, adds some additives simultaneously, as thermo-stabilizer, adds pigment and filler while preparing colored paint.
Photosensitive resin is generally the low-molecular-weight resin with unsaturated link(age), as unsaturated polyester, acrylic oligomers; Photosensitizers is the compound that easily absorbs UV-light generation living radical, as benzophenone, st-yrax alkyl ether; The Main Function of thinner is to reduce dope viscosity, also participates in film-forming simultaneously, is reactive thinner, as vinylbenzene, acrylate etc.
Photo-cured coating advantage is set time short (part second is arrived 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.
The method that traditional paint solidification is normally physical dryness by heating is removed the solvent in macromolecular solution, obtains the paint film of sclerosis.It is utilize the energy of UV-light to cause low molecule performed polymer in coating or oligomer and as the polymerization between the monomer molecule of reactive thinner and crosslinking reaction, obtain the paint film that hardens that UV solidifies, and is in fact to realize chemical seasoning by forming chemical bond.
People have also found some problems in the time using ultraviolet-curing paint, for example traditional photo-cured coating showering tends to have certain gloss on surfaces such as woodenware, metal decking, plastics, require the product surface of low gloss at some, these gloss reducings the use properties of product.The ultraviolet-curing paint that therefore a kind of low gloss is provided is the technology that industry is thirsted for always.
Summary of the invention
The invention provides a kind of ultraviolet-curing paint of low gloss, by mixing the organic quenching powder with dumb light effect, make to there is good dumb light and mobility after the use of this patent coating.
The present invention is achieved by the following technical solutions: a kind of ultraviolet-curing paint of low gloss, component and the weight part of described photo-cured coating are as follows
Further preferably, described modified bisphenol A epoxy diacrylate is fatty acid modified bisphenol A epoxy diacrylate.
Further preferably, described three-functionality-degree reactive monomer is pentaerythritol triacrylate; Described single functionality reactive monomer is hydroxyethyl methylacrylate.
Further preferably, described light trigger is selected from 2-hydroxy-2-methyl-1-phenyl-1-propyl group ketone, TMDPO, 1-hydroxyl-ring ethyl-phenyl ketone, benzoin dimethylether, benzophenone one or more.
Further preferably, described auxiliary agent comprises defoamer and flow agent, and wherein defoamer is silicone based defoamer, and flow agent is that fluorine changes silicon class flow agent; The mass ratio of defoamer and flow agent is 1:1.
The present invention selects the dumb light bisphenol-A epoxy acrylic resin of easy delustring modification and dumb light polyester acrylate as matrix resin, be equipped with the aldol(s) of special organic quenching powder urea element formaldehyde, and there is a bright resistance to powder of Extinction Characteristic, select reactive monomer, matting agent, initiator and the auxiliary agent of the each functionality in certain ratio range simultaneously, the ultraviolet light polymerization coatings with low gloss finish obtaining has good dumb light effect and mobility, there is stronger photoextinction, realized the low gloss effect of coatingsurface.
Embodiment
Below by embodiment, the present invention is further elaborated.
The light curing agent product that the various embodiments described above are made is tested, and through range estimation, above-mentioned each showering coating good fluidity on curtain coater, is applicable to showering operation.Use contrast with normal light solidifying agent product, find that color is obviously dim many, dumb light performance is better.Those skilled in the art will recognize that; above-mentioned embodiment is exemplary; in order to make those skilled in the art can better understand this patent content; should not be understood as the restriction to this patent protection domain; change or modify as long as disclose spiritual any being equal to of doing according to this patent, all fall into this patent protection domain.
