Description
Technical field
The invention belongs to paint field, relate to a kind of wood coating, more particularly, relate to a kind of Gao Guang, wear-resistant ultraviolet ray solidified paint that is used for timber.
Background technology
Ultraviolet-curing paint (UVeuringeoatings is called for short UVCC) is a kind of environment-friendly and energy-efficient coating of the exploitation sixties in 20th century.Since 20th century, realized commercialization the seventies abroad, kept 8% one 10% average annual rate of growth always.It is advantageous that curing speed is fast, almost instantaneous film forming, less use volatile solvent, energy-efficient, but the solidification process automated operation is fit to continuous mass production.UVCC meets pay attention to day by day environmental protection requirement in the our times scope, is described as environmental friendly product of new generation.Its curing light source is generally UV-light (UV), electron beam (EB) and visible light, because electron beam curing apparatus is comparatively complicated, cost is high, and the material of visible-light curing is difficult to preserve, and therefore the most frequently used curing light source still is a UV-light at present.The photo-cured coating advantage is set time short (part second to several minutes), solidification value is low, volatility is low, is to economize the energy, resource-saving, nuisanceless, high efficiency coating new variety; UV solidify then be utilize the energy of UV-light cause in the coating low molecule performed polymer or oligomer and as polymerization between the monomer molecule of reactive thinner and crosslinking reaction; Obtain the paint film that hardens; Selected composition is different or combination is different; Cause performance of products that great difference is arranged, optimize and design new compsn and have great importance for enhancing product performance.
Nineteen sixty-eight, Bayer A.G takes the lead in using the ultraviolet light polymerization system of unsaturated polyester and TRIMETHOXY BENZOIC ACID (FOR MANUFACTURING OF T.M. to process commercially produced product, has developed first-generation ultraviolet-curing paint.Early 1970s, U.S. SUN chemical company and Immont company have successively developed the oleic series UV curable ink.So far, photo-cured coating is able to fast development all over the world, over nearly 20 years, and many quick-setting resin commercializations successively under ultraviolet radiation.At present, its Application Areas has developed into industrial production fields such as decorative plastic, metal parts application, medicine equipment, electronic component, information recording carrier, sensitization printing and optical fiber at present from initial wood finishing.Appear at the Baldor electronics corporation of the U.S. in 1998, be applied to the application of electric motor.The liner of this product can not bear 130 ℃ high temperature with some plastic component; Traditional method is that various parts is assembled after the application respectively with baking vanish again; Can assemble the disposable application in back and use ultraviolet coating, improve efficient greatly and reduced the discharging of volatile organic compounds (VOC).Research at present is the most active, be the application of ultraviolet system on medium density fibre board (MDF) (MDF) the most widely.Along with the minimizing of natural timber resource, MDF is widely used in office and Home furniture.Early 1970s China's ultraviolet-curable materials that begins one's study, Shanghai, Beijing have been set up a collection of ultra-violet curing furniture paint line and paper seasoning machine in succession.Along with the development of macromolecular material, enlarged raw-material range of choice the eighties, quickened the development research of China's photo-curing material, and University Of Tianjin had developed the cruel photocuring woodenware lacquer series of extraordinary vinylformic acid in 1985.
Coating is to be used for a kind of important decoration and materials with function on the timber, and at present, employed UV-light is used for the coating of timber; Mostly be synthetic product; Little with the consistency on the surface of timber, though gloss than higher, the gloss full weight is poor; Wear resistance is not high, is difficult to satisfy the decoration and the wear-resisting needs of high-grade timber.Simultaneously, curing speed is also slower, in natural product, rosin be have tough and tensile; Attrition resistant advantage, but film-forming properties is bad, therefore; Keep the characteristics of natural rosin, it is fast that natural rosin is modified as curing speed, and the material that becomes UV curable has great importance to the raising of furniture class.
Summary of the invention
It is poor to the objective of the invention is for solving existing ultraviolet-curing paint full weight, and gloss is not soft, the insufficient technical problem of wear resistance, provides a kind of glossiness full, soft, wear-resisting, the ultraviolet-curing paint that is used for timber of completion of cure.
In order to realize above-mentioned target, the present invention is to be main film forming substance through adopting epoxy acrylic resin; Utilize rosin derivative, improve and solidify back coating gloss; Utilize amino rosin and crylic acid verivate to improve the glossy plumpness, realize fast setting; And adopt oxidation VT 18 vinyl resin to strengthen the soft property of paint film.Its concrete technical scheme of dealing with problems is:
A kind of ultraviolet-curing paint that is used for timber; Content is 30%～50% by epoxy acrylic resin by mass percentage, and the rosin and crylic acid verivate is 10%～20%, and amino rosin and crylic acid verivate is 10～20%; Nano-aluminium oxide is 5～30%; Oxidation VT 18 vinyl resin is 1～5%, and KH560 is 0.1～1%, 1173 to be 1～5% to form;
Wherein, the molecular structure of described rosin and crylic acid verivate is:
It derives from the product of rosin derivative and Hydroxyethyl acrylate reaction acquisition;
The molecular structure of described amino rosin and crylic acid verivate is:
It derives from the product of amino rosin derivative and Hydroxyethyl acrylate reaction acquisition.
A kind of preparation method who is used for the ultraviolet-curing paint of timber of the present invention is that first liquid ingredient with the technical formula component mixes, and adds solid ingredient then and stirs, and on shredder, grinds last can again.
A kind of ultraviolet-curing paint that is used for timber of the present invention is compared the advantage and the effect that have and is with currently available products:
1, solidifies back coating glossy rosin derivative owing to having adopted to improve, so the glossiness of paint film is high;
2, owing to having utilized amino rosin and crylic acid verivate, so improved the glossy plumpness, soft property, wear resistance and curing speed;
3, owing to adopted oxidation VT 18 vinyl resin, strengthened the soft property of paint film.
