The invention relates to matte finishing clear coat and a preparation method thereof. The matte finishing clear coat is made from the following materials according to percent by weight: 25-65% of core-shell acrylic copolymer emulsion, 0.05-6% of a thickener, 0.1-5% of a rheological aid, 0.1-0.6% of a dispersant, 0.1-0.6% of a wetting agent, 1.5-2% of a film-forming aid, 0.5-5% of a wax emulsion, 0.1-0.5% of a defoaming agent, 1.5-7.0% of a functional aid, and 20-65% of water. The matte finishing clear coat is still good in matte effect even no matting agent is added, storage stability of a system is good, a coat film has good transparency and water white resistance, and the matte finishing clear coat has excellent comprehensive performance.

The invention belongs to the technical field of UV curing coatings, and specifically relates to a silicon-modified matte UV resin. ~25 parts, polyol 15~25 parts, first catalyst 0.3~0.4 parts, second catalyst 0.02~0.03 parts, polymerization inhibitor 0.05~0.1 parts, stabilizer 0.05~0.1 parts, neutralizer 5~10 parts, 15-20 parts of water. The resin is not easy to change color and crack under high temperature, and at the same time, it can achieve a matte effect without adding a matting agent, and has high use value and good application prospect.

The invention belongs to the technical field of photocuring, and particularly relates to a device for lamp manufacturing of a super-matte skin feeling plate. The device comprises a gallium lamp box, an xenon lamp box and a mercury lamp box which are arranged in sequence in the conveying direction of the plate, a conveying belt used for conveying the plate is arranged among the three lamp boxes, meanwhile, a seal space used for containing the plate which is conveyed in place through the conveying belt is further included, an oxygen displacement device is arranged in the xenon lamp box, and ultraviolent light with the wavelength being 172 nm is generated in the oxygen displacement device. A 172 nm quasimolecule xenon lamp is adopted for radiating a UV coating, due to the limited penetratingcapacity of the ultraviolet light at the wave segment, a coating with the thickness about 0.1 micrometer on the surface of the coating is subjected to photocuring, the coating with the larger thickness is still in a liquid state, therefore, the photocured surface layer coating can generate uniform wrinkles due to the shrinkage reason, the microcosmic concave and convex surface can be generated, the matte skin feeling effect is achieved, the defect that extinction powder cannot achieve the super-matte skin feeling is overcome, and extinction powder is not needed.

The invention discloses a weather-resistant matte PC / ASA alloy material, which comprises the following components in parts by weight: 69-75 parts of bisphenol A polycarbonate resin, acrylate rubber-acrylonitrile-styrene bonded Branch copolymer 14-20 parts, silicone toughening agent 3-7 parts, compatibilizer 2-4 parts, matting agent 4 parts, hindered phenolic antioxidant 0.2 part, auxiliary antioxidant 0.2 part, ultraviolet absorber 0.3 parts and lubricant 0.2 parts. The alloy material is made of bisphenol A polycarbonate, acrylic rubber, acrylonitrile and styrene graft copolymer as the main raw materials, supplemented by silicone compatible toughening, organic matting agent, high-efficiency antioxidant and special UV Absorbent and other components are combined, and the synergy of each component is used to achieve a matte matte effect on the surface of the material; the alloy material has the performance of weather resistance and high cold resistance, and has excellent physical properties, which can meet the requirements of outdoor weather resistance and can be widely used Used in automotive interior and exterior decoration, office equipment, communication equipment and outdoor lighting components.

The invention discloses non-treatment frosted varnish ink for PET (polyethylene terephthalate) film gravure. The ink is characterized by comprising varnish, a diluent and a curing agent in the weight ratio being 10:(4-18):0.5, wherein the varnish comprises components in percentage by weight as follows: 25%-40% of a polyurethane resin liquid, 3%-7% of butyl acetate, 8%-12% of ethyl acetate, 8%-25% of an inorganic pigment, 1%-3% of PE wax powder, 2%-4% of a dispersing agent, 15%-20% of a modified material and 20%-35% of n-propyl acetate. With the adoption of the ink prepared with the formula, a common PET light film can be locally matted or completely matted through printing, and the beauty of a product is improved; the matt degree of the product is freely controlled to range from 2 degrees to 15 degrees through adjustment of the addition proportion of the diluent of the varnish ink and the depth of a printing plate; the matt effect is realized through the common PET film, the cost is low, and preparation is convenient.

The invention discloses a non-thickening ultraviolet curing coating and a preparation method thereof. The coating comprises the following components in parts by weight: fillers include transparent spherical micropowder and fumed silica micropowder, and functional assistants include dispersant, defoamer, leveling agent, photoinitiator assistant and photoinitiator. The thinner is used to reduce the viscosity of the coating so that the coating can be leveled. The crosslinking speed of the hydroxy acrylic resin and the urethane acrylate is slow, and it is easy to rework; the thinner forms a hydrogen bond with the surface of the coating to improve the adhesion and prevent paint stripping. The structure of the double bond, ester group and alkane makes the paint film have better elongation at break; the dispersant disperses the urethane acrylate, and the paint is not easy to thicken; the filler increases the roughness of the paint film and reduces the gloss to achieve a matte effect , to solve the problems existing in existing coatings.
