High flow flat imitating steam mold UV curing coating and production method, construction method

Abstract

The invention relates to a high-leveling vapor die imitating UV-curing coating, a production method and a construction method thereof. The coating comprises black primer or silver primer, a primer diluent and UV radiation curing varnish, wherein the primer diluent comprises 8 to 15 portions of ethylene glycol monobutyl ether, 5 to 10 portions of diacetone alcohol, 5 to 15 portions of ethylene glycol monoethyl ether, 5 to 15 portions of methylisobutylketone, 25 to 35 portions of ethyl acetate, 10 to 15 portions of isopropyl alcohol and 10 to 15 portions of isobutyl alcohol; and the UV radiation curing varnish comprises 10 to 15 portions of tripropylene glycol diacrylate, 10 to 15 portions of trimethylol-propane trimethacrylate, 20 to 30 portions of amino acrylate resin, 7 to 15 portions of Epocryl, 3 to 6 portions of 1-hydroxyl-cyclohexyl-phenyl ketone, 0.5 to 1 portion of 2, 4, 6(trimethylbenzene formacyl) diphenyl phosphine oxide, 15 to 25 portions of ethyl methyl ketone, 0.5 to 1.5 portions of polyacrylate leveling agent and 0.5 to 1.5 portions of polyether siloxane copolymer. The invention also provides a manufacturing method and a use method for the product. The high-leveling vapor die imitating UV-curing coating, is widely applied to treatment of plastic shells such as TV sets, so that the surface of a treated plastic substrate can achieve the effect of high-leveling vapor die imitating.

Description

technical field [0001] The invention relates to a high-leveling steam mold-like UV curing coating and its production method and construction method. The method is especially suitable for use on plastic casings such as HIPS, PS, ABS, ABS+PC materials, so that it has a high-gloss non-marking injection molding effect . Background technique [0002] Many types of flat-panel TV covers on the market are currently injection-molded using the "high-gloss non-marking injection molding" technology to achieve a high-gloss mirror-effect surface, which has a gloss and smooth effect that cannot be compared with ordinary injection molding. Some foreign brands such as Samsung, SONY and other flat-panel TV manufacturers have applications, but because the materials used in this technology are much more expensive than ordinary HIPS and ABS, and the injection molding equipment (mold) is expensive, the maintenance cost of injection molding is high, and special steam generation is required.

Problems solved by technology

[0002] Many types of flat-panel TV covers on the market are currently injection-molded using the "high-gloss non-marking injection molding" technology to achieve a high-gloss mirror-effect surface, which has a gloss and smooth effect that cannot be compared with ordinary injection molding. Some foreign brands such as Samsung, SONY and other flat-panel TV manufacturers have applications, but because the materials used in this technology are much more expensive than ordinary HIPS and ABS, and the injection molding equipment (mold) is expensive, the maintenance cost of injection molding is high, and special steam generation is required. Due to the low pass rate of equipment and injection molding (70-80%), etc., the cost of the shell produced by this technology is high. In addition, because of this technology, there is a serious deficiency: the surface is poor in scratch resistance, and the use of common Wiping with a towel will leave obvious scratches, which seriously affects the appearance retention of TV products

However, ordinary injection molding and coatings and construction methods currently in use are low in cost but cannot achieve the appearance of the surface shell produced by the "high leveling imitation steam mold" technology. Therefore, many TV manufacturers have urgent requirements for new coatings and construction technologies.
