The ultraviolet curing coating comprises components by weight percentage of: 30 to 50% of epoxy acrylate, 10 to 20% of rosin acrylic acid derivative, 10 to 20% of amino rosin acrylic acid derivative, 5 to 30% of nanometer aluminium oxide, 1 to 5% of oxidized soya bean oil acrylic resin, 0.1 to 1% of KH560, and 1 to 5% of 1173. The ultraviolet curing coating for the wood has the characteristics and effects of full range of glossiness, softness, wear resistance, and fast speed in curing.
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 for timber, wear-resistant ultraviolet ray solidified paint.
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 20 century 70s are realized commercialization abroad, kept 8% one 10% average annual growth always.It is advantageous that curing speed is fast, almost instantaneous film forming, less use volatile solvent, energy-efficient, solidification process can automated operation, is applicable to continuous mass production.UVCC meets the requirement of pay attention to day by day environmental protection within the scope of our times, is described as environmental friendly product of new generation.Its curing light source is generally UV-light (UV), electron beam (EB) and visible ray, 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 is still UV-light at present.Photo-cured coating advantage is set time short (part second is arrived several minutes), solidification value is low, volatility is low, is to economize the energy, resource-saving, nuisanceless, high efficiency coating new variety; It is to 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 that UV solidifies, obtain the paint film that hardens, selected composition is different or combination is different, cause the performance of product to have great difference, optimize and design new composition and have great importance for enhancing product performance.
Nineteen sixty-eight, Bayer A.G takes the lead in using the UV curing system of unsaturated polyester and M-nitro benzoic acid to make commercially produced product, has developed first-generation ultraviolet-curing paint.Early 1970s, SUN chemical company of the U.S. and Immont company have successively developed 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 now developed into the field of industrial productions such as decorative plastic, metal parts application, medicine equipment, electronic component, information recording carrier, photosensitive printing and optical fiber from initial wood finishing.The Baldor electronics corporation that appears at the U.S. for 1998, is applied to the application of electric motor.The liner of this product and some plastic component can not bear the high temperature of 130 DEG C, traditional method is that different parts baking vanish is assembled after application respectively again, and application ultraviolet coating can assemble rear disposable application, greatly improve efficiency and reduced the discharge of volatile organic compounds (VOC).At present research 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 polish machine in succession.The eighties, along with the development of macromolecular material, has expanded raw-material range of choice, has accelerated the development research of China's photo-curing material, and within 1985, University Of Tianjin has developed the cruel photocuring woodenware lacquer of special acrylic acid series.
Coating is the material for a kind of important decoration and function on timber, at present, the UV-light using is for the coating of timber, mostly be synthetic product, little with the surperficial consistency of timber, although gloss is higher, gloss full weight is poor, wear resistance is not high, is difficult to meet decoration and the wear-resisting needs of high-grade timber.Meanwhile, curing speed is also slower, in natural product, rosin be have tough and tensile, wear-resisting advantage, but film-forming properties is bad, therefore, the feature that retains natural rosin, is modified as curing speed by natural rosin fast, 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 object of the invention is for solving existing ultraviolet-curing paint full weight, and the technical problem that gloss is not soft, wear resistance is not enough provides a kind of glossiness full, soft, wear-resisting, the ultraviolet-curing paint for timber of completion of cure.
In order to realize above-mentioned target, the present invention is to be main film forming substance by adopting epoxy acrylic resin; Utilize rosin derivative, improve and solidify rear coating gloss; Utilize amino rosin and crylic acid derivative to improve the plumpness of gloss, realize fast setting; And adopt oxidation soybean oil acrylic resin to strengthen the mildness of paint film.Its concrete technical scheme of dealing with problems is:
A kind of ultraviolet-curing paint for timber, content is 30%～50% by epoxy acrylic resin by mass percentage, rosin and crylic acid derivative is 10%～20%, amino rosin and crylic acid derivative is 10～20%, nano-aluminium oxide is 5～30%, oxidation soybean oil acrylic resin is that 1～5%, KH560 is 0.1～1%, 1173 to be 1～5% composition;
Wherein, the molecular structure of described rosin and crylic acid derivative is:
It derives from rosin derivative and reacts the product obtaining with Hydroxyethyl acrylate;
The molecular structure of described amino rosin and crylic acid derivative is:
It derives from amino rosin derivative and reacts the product obtaining with Hydroxyethyl acrylate.
The preparation method of a kind of ultraviolet-curing paint for timber of the present invention first mixes the liquid ingredient of technical formula component, then adds solid ingredient to stir, then grinds on shredder, finally filling.
A kind of advantage having compared with currently available products for the ultraviolet-curing paint of timber of the present invention and effect are:
1, can improve owing to having adopted the rosin derivative that solidifies rear coating gloss, so the glossiness of paint film is high;
2, owing to having utilized amino rosin and crylic acid derivative, so improved the plumpness of gloss, mildness, wear resistance and curing speed;
3, owing to having adopted oxidation soybean oil acrylic resin, strengthened the mildness of paint film.
