Abstract

A design of plastic industrial products was manufd. by setting the synthtic resin with the pearl flakes. Thus, "polycoat8000A" and "H510" were mixed with each other at the mixture ratio of 1:1-1:2 and the above mixture was stirred with pearl flakes at the mixture ratio of 100:1.5 to make the plastic art products. In the manufg. process, the working temp. was maintained below 28OC and the mixture was poured into the mold at a speed of 2.5-4 l/hr.

Description

Pattern forming method for crafts made of synthetic resin

본 발명은 합성수지로 공예품의 무늬를 형성시키는 방법에 관한 것으로 특히 장신구, 고급단추 등을 제조함에 있어 입사광선에 의해 무늬가 다양하게 변하도록 하는 공예품의 제조방법을 제공하려는데 있다.The present invention relates to a method of forming a pattern of a craft with a synthetic resin, and in particular to provide a method of manufacturing a craft to vary the pattern by the incident light in the manufacture of jewelry, high-quality buttons and the like.

종래의 제조방법은 합성수지에 금속박편을 침투시켜 제조하는 것이 있으나 이는 무늬가 일정하고 다양한 무늬의 변화를 얻지 못하였다. 또 세루로이드에 물결무늬를 형성시키는 방법도 오래전부터 알려진 바 있으나 이를 이용하여 장신구와 같은 고급 공예품은 만들 수가 없다. 한편 어린박(魚麟薄)으로 합성수지에 첨가하는 것도 알려진 것이나 합성수지가 용융 상태에 있을 때 첨가하므로 표면 광택을 상실하여 입사광선에 의한 무늬의 변화가 없어서 고급품으로 사용하기에는 부적당하다.The conventional manufacturing method is to penetrate the metal flakes in the synthetic resin, but it is produced, the pattern is constant and did not obtain a variety of changes in the pattern. In addition, the method of forming a wave pattern on a ceroid has been known for a long time, but it cannot be used to make high-quality crafts such as jewelry. On the other hand, it is also known that it is added to synthetic resin as a young foil, but when the synthetic resin is in a molten state, it loses surface gloss and is not suitable for use as a high-end product because there is no change of pattern by incident light.

본 발명 방법에 의거 제조되는 공예품은 움직임에 따라 무늬가 움직이는 형태로 반사되어 아름답고, 이를 가공하여 여러가지의 장신구나 공예품을 만들 수가 있다.Crafts produced according to the method of the present invention is beautiful in the form of a pattern moving in accordance with the movement is beautiful, it can be processed to create a variety of ornaments or crafts.

본 발명에서 원료로 사용되는 합성수지는 특히 애경유지제 폴리에스텔인 상품명 포리코트 H530와 포리코트 8, 000A을 사용하고, 이들 혼합비는 1 : 1-1 : 2의 비가 가장 이상적이었으며, 여기에 혼합하는 진주박은 폴리에스텔 수지의 1-2.5중량% 주입하되 봉의 내경에 따라 1-60㎝의 거리에서 2.5-4ℓ/hr의 속도로 주입하여 만들면 진주박 입자에 의한 빛의 반사는 주입시키는 위치와 거리에 따라 구슬형 또는 지문형등의 여러가지 형태의 무늬가 발현(發現)된다.Synthetic resin used as a raw material in the present invention in particular is a polyester film made by Aekyung holding the product name Poricoat H530 and Poricoat 8, 000A, the mixing ratio of the ratio of 1: 1-1: 2 was the most ideal, it is mixed Pearl foil is injected by 1-2.5% by weight of polyester resin, but it is made by injecting at a speed of 2.5-4ℓ / hr at a distance of 1-60cm according to the inner diameter of the rod. As a result, various types of patterns such as beads or fingerprints are expressed.

본 발명을 실시예와 함께 상술하면 다음과 같다.The present invention will be described below with reference to Examples.

공지된(상품명)포리코트 8, 000A와 포리코트 H530을 1 : 1의 비로 혼합하여 교반한 다음 진주박을 폴리에스텔 수지에 대해 1.5중량%를 혼합하여 입자가 충분히 풀리도록 교반한다.Known (trade name) Poricoat 8,000A and Poricoat H530 are mixed and stirred in a ratio of 1: 1, and then the pearl foil is mixed with 1.5 wt% of the polyester resin to stir sufficiently to loosen the particles.

이때 액체의 점도에 따라 박의 정렬 상태가 상이해지므로 작업온도를 28℃이하로 하고, 배합과정에는 진공펌프를 이용하여 탈포(脫泡)시킨 것을 봉에 주입하되 봉의 내경에 따라 1-60㎝의 거리에서, 2.5-4ℓ/hr의 속도로 주입한다.At this time, since the alignment of the foil is different according to the viscosity of the liquid, the working temperature should be 28 ℃ or less, and during the compounding process, the degassed liquid is injected into the rod using a vacuum pump, but 1-60㎝ according to the inner diameter of the rod. At a distance of 2.5-4 l / hr.

이때 봉에 주입하는 위치와 거리에 따라 무늬가 상이하게 형성된다. 이와같이 주입한 봉은 경화탱크에 넣고 30-65℃의 온도를 유지하면 1-3시간만에 폴리에스텔은 겔화가 되어 서서히 경과되나, 이때 경화온도를 잘 유지하지 못하면 제품에 균열이 되거나 변색이 되므로 주의해야 한다.At this time, the pattern is formed differently according to the position and distance injected into the rod. If the rod is injected into the curing tank and maintained at a temperature of 30-65 ℃, the polyester will gel slowly within 1-3 hours, but if the curing temperature is not maintained well, the product will crack or discolor. Should be.

이와같이 경화된 것을 필요한 길이로 절단하여 요구되는 장신구 동으로 가공처리하면 다양하게 변화는 무늬가 형성된 제품이 만들어지고, 가공된 제품은 중성세제로 깨끗이 씻고 원심분리기에 의해 탈수하여 건조하고, 희석된 수지를 분무하여 상온에서 20-30분 방치한 뒤 전기로에 넣어 서서히 120℃까지 가열경화시킨다.When the cured product is cut to the required length and processed with the required ornaments, variously changed products are formed. Patterned products are washed with a neutral detergent, dehydrated by a centrifuge, and dried and diluted. After spraying, the mixture was left at room temperature for 20-30 minutes, and placed in an electric furnace to be slowly cured to 120 ° C.

Claims
