Description

고투명성 조명커버용 터널형 오닉스 성형품의 제조방법{omitted}Manufacturing method of tunnel type onyx molded article for high transparency lighting cover

본 발명은 고투명성 조명커버용 터널형 오닉스(ONYX) 성형품의 제조방법에 관한 것으로, 더욱 상세하게는 폴리에스테르 수지분말과 백석분(白石紛) 및 투명경 화제를 혼합 주조성형시켜 기존유리 성분으로 주조된 오닉스 성형품에 비해 투명성과 저균열성이 매우 우수한 오틱스 성형품을 만들수 있는 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a tunnel-type onyx (ONYX) molded article for a high-transparent lighting cover, and more specifically, by mixing and molding a polyester resin powder, a white stone powder and a transparent hardener as an existing glass component The present invention relates to a manufacturing method capable of making an ortic molded article having excellent transparency and low cracking properties compared to a molded onyx molded article.

기존의 유리분말로 사용되는 오닉스 성형품은 주조시 단면이 반원형이고 길이가 30 ∼ 45cm 정도의 크기로 성형시킬 경우 중온의 액상에서 상온으로 온도변화에 따르는 파손율이 25 ∼ 35%로 높아 생산효율이 현저하게 낮고 오닉스 성형품의 길이가 45 ∼ 90cm 정도되는 제품은 주조시 성형되는 과정에서 대부분 파손되므로 길이가 긴 제품은 생산을 포기하기에 이른 것이다.Onyx molded products, which are used as conventional glass powders, have semi-circular cross-sections when casting and have a length of about 30 to 45 cm. Remarkably low products of about 45-90 cm in length onyx molded products are mostly broken during the molding process, so long products are abandoned.

한편, 유리성분으로 제조 된 오닉스 성형품을 형광등이나 각종 조명등에 커버를 씌위 사용할 경우에는 조도가 낮은 반면 표면에 모래알과 같은 작은 점상의 그림자가 나타나므로 눈의 피로를 느끼게 하는 등의 우수한 결점이 수반되었던 것이다.On the other hand, when using onyx molded articles made of glass components to cover fluorescent lamps or various lighting lamps, the illuminance is low, but small dots such as sand grains appear on the surface, leading to excellent defects such as eye fatigue. will be.

그리고, 사용시 유리로 성형된 터널형 오닉스 성형품은 강도가 낮으므로 취급상 부주의로 파손될 경우 예리한 파편이 방사형으로 튀어 인명피해의 위험을 안겨주는 등의 여러가지 문제점이 제기되었던 것이다.In addition, the tunnel-shaped onyx molded article formed of glass has a low strength, and thus, various problems have been raised such that sharp debris splashes radially and causes a risk of human injury if the handle is inadvertently broken.

따라서, 본 발명은 오닉스 성형품의 성분을 유리성분보다 투명성 및 저균열성이 매우 우수한 성분으로 대체하여 상술한 제반 문제점을 일거에 해소시켜 주어 경제적 효율을 높이고 고투명성으로 보다 깨끗하고 선명한 빛을 밝혀주며 강도가 높아서 저균열성이 매우 우수하여 오닉스 성형품의 취급시 파손율이 현저히 떨어지므로 안전성을 높여주는 등의 효과가 있는 한편, 유리 오닉스 성형품에 비해 본 발명품은 중량이 1/2 이하의 경량이므로 취급이 간편한 매우 효과적인 발명인 것이다.Therefore, the present invention replaces the components of the onyx molded article with a component having a very high transparency and low cracking property than the glass component to solve the above-mentioned problems at a glance, thereby improving economic efficiency and revealing clear and clear light with high transparency. Due to its high strength and very low cracking property, the breakage rate is considerably reduced when handling onyx molded products, which increases the safety.However, compared to glass onyx molded products, the present invention has a light weight of 1/2 or less, so it is handled. This is an easy and very effective invention.

..

본 발명은 상술한 효과를 제공하기 위하여 폴리에스테르 수지 분말 45∼ 54% 백석분 45 ∼ 54% , 투명경화제 1% 의 비율로 100℃ 의 온도로 혼합시키고, 희석점도는 3 ∼ 15 포이즈 하여 성형틀에 부어 성형시키고 성형된 터널형 오닉스 성형품을 87 ∼ 93℃ 로 열처리를 하여 각각의 성분에서 배어 있는 특유의 냄새를 제거하기 위하여 본 발명의 터널형 오닉스 성형품을 제조하는 방법으로서 폴리에스테르 수지분말과 백석분 및 투명경화제 성분의 특성을 살려 준 것이므로 고투명성과 저균열성이 매우 우수한 발명품을 제공하여 기존 유리 오닉스 성형품의 길이를 45 ∼ 90cm 이상으로 제조하여도 파손율이 현저히 떨어지므로 높은 생산효율을 도모할 수있는 발명인 것이다.In order to provide the above-mentioned effect, the present invention is mixed at a temperature of 100 ° C. in a proportion of 45 to 54% of polyester resin powder 45 to 54% of white powder and 1% of a transparent hardener, and the dilution viscosity is 3 to 15 to form a mold. A polyester resin powder and white stone as a method for producing the tunnel-type onyx molded article of the present invention in order to remove the characteristic odors inherent in each component by heat-treating the molded tunnel-shaped onyx molded article at 87-93 ° C. As it utilizes the characteristics of powder and transparent hardener components, it provides an excellent invention with high transparency and low cracking property. Even if the length of existing glass onyx molded product is manufactured to 45 ~ 90cm or more, the breakage rate is remarkably decreased. It is an invention that can be.

본 발명은 상술한 바와 같이 기존의 유리성분으로 주조 성형시켜서 제조하는 오닉스 성형품에서 발생되는 제반 문제점을 일거에 해소시켜 준 발명으로서,As described above, the present invention solves all the problems caused by the onyx molded product manufactured by casting and molding an existing glass component.

첫째는, 고투명성으로 유리성분의 오닉스 성형품에 비하여 빛의 밝기가 현저히 깨끗하고 선명하여 조도를 한층 높혀주고,First of all, it is highly transparent, so the brightness of light is remarkably clear and clear compared to glass-based onyx molded products, which enhances illuminance.

둘째는, 폴리에스테르 수지분말과 백석분의 성분 특성상 유리제품에 비하여 매우 우수한 저균열성이 내제되어 있어 제조시 발생되는 불량률을 80 ∼ 95% 이상으로 감소시켜주어 생산성 향상을 도모함과,Secondly, due to the characteristics of polyester resin powder and white stone powder, it has a very low cracking resistance, which is superior to glass products, and reduces the defective rate generated during manufacturing to 80 to 95% or more, thereby improving productivity.

셋째는, 1/2 이상 경량이며 견고한 제품으로서 시공이 매우 간편하며 사용시에도 파손율이 현저히 낮고,Thirdly, it is light weight and durable product more than 1/2, so construction is very simple and the breakage rate is very low even when using,

넷째는, 취급시 파손이 되어도 파편이 유리조각과 같이 예리하지 않으므로 인명손상을 한층 줄여 주는 안정감이 높은 제품을 제공하는 등의 매우 효과적이면서 유용한 발명인 것이다.Fourthly, since the fragments are not as sharp as glass fragments even when handled, they are very effective and useful inventions, such as providing a highly stable product that further reduces human injury.
