Description
PRODUCTION METHOD OF MOLDING MIXTURE OF
SYNTHETIC RESIN USING URUSHI LACQUER MIXTURE
AND MOLDING MIXTURE OF SYNTHETIC RESIN
PRODUCED BY THEREOF Technical Field
[1] The present invention relates to a method of producing an injection- molding product of synthetic resin using a mixture of ink and urashi lacquer and an injection- molding product of synthetic resin produced thereby. More particularly, the present invention relates to a method of producing an injection-molding product of synthetic resin using a mixture of ink and urushi lacquer, which comprises mixing synthetic resin, ink, and urushi lacquer, flattening and drying the mixture, crushing the dried mixture, and injection-molding the crushed mixture, and to an injection-molding product of synthetic resin produced thereby. Background Art
[2] In general, raw urushi lacquer or urushi lacquer collected from the lacquer tree is known to be composed of 55~66% urushiol, 25~30% water, 5-10% monosaccharides and polysaccharides, 3-5% of nitrogen-containing material, and small amounts of enzymes, such as laccase, stellacyanin, and peroxidase. Urushi lacquer, which is a kind of natural resin, has been used in large amounts, mainly by being applied on wood to produce articles for living, such as wardrobes, vessels, spoons, chopsticks, and tables, in Korea, China and Japan for thousands of years. Further, it is also known that urushi lacquer has advantages such as high flame resistance, heat resistance, rot resistance, insect resistance, and electrical insulation properties, and furthermore, that the preservative quality thereof is good.
[3] Recently, much research effort has been directed toward the preparation of functional polyethylene resin containing urushi lacquer (Korean Patent Laid-open Publication No. 2000-0024493). Specifically, such a resin is characterized in that it is obtained by dissolving a polymer material for use in synthetic resin to a concentration of 10 wt% in an organic solvent, adding refined urushi lacquer thereto in an amount not greater than 20 wt% based on the weight of the polymer material, casting the mixture solution of polymer and urushi lacquer, and drying it, or by increasing the temperature of a polymer material for use in synthetic resin to its melting temperature to thus form a polymer melt, adding urushi lacquer thereto in an amount not greater than 20 wt% based on the weight of the polymer, and stirring the urushi lacquer and
the polymer melt to produce a melt mixture of polymer and urushi lacquer, which is then extruded through a slit die, quenched using a roller, and thereafter solidified.
[4] However, the above-mentioned method is disadvantageous because the urushi lacquer is used in a maximum amount of 20 wt% in order to be uniformly mixed with the polymer, thus it is not easy to add the urushi lacquer in other amounts so as to more strongly exhibit the main properties of urushi lacquer. Disclosure of Invention Technical Problem
[5] Accordingly, the present invention has been made keeping in mind the above problems occurring in the related art, and an object of the present invention is to provide a method of producing an injection-molding product of synthetic resin using a mixture of ink and urushi lacquer, in which synthetic resin is stably mixed with a high concentration of urushi lacquer to produce an injection-molding product, and is further mixed with ink to realize various colors.
[6] Another object of the present invention is to provide an injection-molding product of synthetic resin using a mixture of ink and urushi lacquer, which exhibits good absorption of harmful electromagnetic waves, far infrared emissivity, antibacterial activity, and durability, produced by the above method. Technical Solution
[7] In order to achieve the above objects, the present invention provides a method of producing an injection-molding product of synthetic resin using a mixture of ink and urushi lacquer, which comprises mixing a synthetic resin pellet or powder, 1-90 wt% of filtered urushi lacquer, and l~90 wt% of ink, based on the total weight of the synthetic resin pellet or powder, flattening the mixture to a thickness of 2~5 mm and then drying it at 100~160°C for 3-5 hours, crushing the dried mixture to a size of 2-300 mesh, and injection-molding the crushed mixture.
[8] Hereinafter, a detailed description will be given of the present invention.
[9] Examples of the synthetic resin used in the present invention include polyethylene terephthalate (PET), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), ABS resin (acrylonitrile-butadiene-styrene copolymer), fluorine resin, nylon resin, acryl resin, poly acetic acid vinyl resin, polyamide resin, acetal resin, polycarbonate (PC), polyphenylene oxide, polyester, and polysulfone. In particular, ABS resin, nylon resin or acryl resin is preferable. The synthetic resin is used in the form of a pellet or powdered product. Typically, since the synthetic resin has a lot of dust attached thereto due to static electricity, such dust must be reliably removed upon a printing process. In order to solve the problem, proposed are methods of subjecting new equipment to antistatic treatment and of using an
antistatic agent.
[10] In the present invention, urushi lacquer, which is native to Korea, China, Japan and
Southeast Asia, may be used without limitation. Further, although the composition of such lacquer may vary with the production region, it may also be independent thereof. Further, in the present invention, the urushi lacquer is used after a filtration process using filter paper to remove impurities therefrom. Accordingly, the urushi lacquer thus filtered is added to the synthetic resin pellet or powder in an amount of 1-90 wt% based on the total weight of the synthetic resin pellet or powder, and also ink is added thereto in an amount of 1-90 wt% based on the total weight thereof. Thereby, it is possible to produce an injection-molding product of urushi lacquer-containing synthetic resin capable of realizing various colors thanks to the addition of ink. As such, for easy mixing and clear color, the ink is preferably used in the form of pigment powder, which is a raw material thereof.
[11] Then, the resulting mixture is flattened to a thickness of 2-5 mm and then dried at
100~160°C for 3-5 hours. Moreover, the process of applying the mixture of the synthetic resin pellet or powder and urushi lacquer is realized using the viscosity of the urushi lacquer itself. However, when the amount of urushi lacquer exceeds 20 wt%, the urushi lacquer is difficult to mix further and melt with the synthetic resin pellet or powder. Therefore, with the goal of preparing synthetic resin comprising a high concentration of urushi lacquer to maximize the effect of the urushi lacquer, the present inventors have devised a method of flattening and drying the mixture of such urushi lacquer and synthetic resin pellet or powder.
[12] The dried mixture is subjected to a crushing process using a crusher until it has a size of 2-300 mesh, after which the crushed mixture is loaded into an injection- molding machine so as to perform an injection-molding process using a mold having a desired shape. As such, the injection-molding process is preferably carried out under conditions of an injection pressure of 40-60 kg/cm2, an injection rate of 30-40%, a cooling time period of 20-50 sec, and a temperature of 180~260°C.
[13] In addition, the present invention provides an injection-molding product of synthetic resin including a mixture of ink and urushi lacquer, produced by the above method. Consequently, the injection-molding product of the synthetic resin including the mixture of ink and urushi lacquer, produced by the method of the present invention mentioned above, has good absorption of harmful electromagnetic waves, far infrared emissivity, antibacterial activity, and durability.
Advantageous Effects
[14] According to the present invention, the method of producing the injection-molding product of a synthetic resin mixture enables the production of an injection-molding
product of synthetic resin, which includes urushi lacquer that is added even at a high concentration of 20 wt% or greater, as well as at a low concentration, and which is able to realize various colors. Therefore, since the injection-molding product thus produced has good far infrared emissivity, antibacterial activity and durability, and high hardness, it may be variously applied to TV sets, mobile phones, notebook computers, automobile interior materials, construction materials, various cases, etc. Brief Description of the Drawings
