Abstract
Description
본 발명은 실리콘 성형제품 제조방법에 관한 것으로서, 좀더 상세하게는 실리콘 소재로 성형되는 제품의 제조방법을 개선하여 성형제품에 따른 경화시간을 단축하여 경화시간으로 인한 제품의 불량을 없앨 수 있도록 하는 반면에, 균일한 제품의 생산성을 향상시킬 수 있도록 한 것이다.The present invention relates to a method for manufacturing a silicone molded product, and more particularly, to improve the manufacturing method of a product molded from a silicone material, thereby shortening the curing time according to the molded product, thereby eliminating defects of the product due to the curing time. In order to improve the productivity of the uniform product.
일반적으로 연질 제품의 실현을 위해 사용되는 실리콘(SILICONE)은 어떠한 형태의 다른 탄성체 소재와도 비교할 수 없는 안정된 화학구조를 가지고있으며, 부식성이 없고 산화되지 않는 화합물로서 내열, 내한, 전기절연, 화학적 안전성, 내마모성, 광택성, 풍부한 탄성 등 여러 가지 특성을 갖추고 있어 의료용품, 전기제품, 스포츠용품, 자동차용품 등 다양한 제품에 사용되고 있다.. 또한 화학적 합성, 반응 및 소재의 혼합(COMPOUNDING)기술에 의해 자유롭게 물리적, 전기적 특성 (초절연, 초내열, 초난연 등 ) 을 부여할 수 있는 첨단 소재로 사용되고 있다.Generally, SILICONE, which is used for the realization of soft products, has a stable chemical structure that is incomparable with any other elastomeric material, and is a non-corrosive and non-oxidizing compound. It is resistant to heat, cold, electrical insulation and chemical safety. It has various characteristics such as wear resistance, glossiness, and abundant elasticity. It is used in various products such as medical products, electrical appliances, sports goods, and automobile products. Also, it is freely made by chemical synthesis, reaction, and compounding technology. It is used as an advanced material that can give physical and electrical characteristics (super insulation, ultra heat resistance, super flame retardancy, etc.).
실리콘의 분류를 살피면, 실리콘고무는 경화온도에 따라 크게 열을 가해주어야 경화되어 탄성체로 되는 고온경화용(HIGH TEMPERATURE VULCANIZING)과 상온에 방치하는 것만으로 탄성체가 되는 상온경화용(ROOM TEMPERATURE VULCANIZING)으로 분류되어 있으나, 최근에 들어서 부가반응을 이용한 액상실리콘고무가 상용화되면서 종래의 경화온도만으로 실리콘을 분류할 수 없게 되었다. 이러한 이유에서 다시 몰리머의 중합도나 점도에 따라서 실리콘을 분류하게 되었는데, 이렇게 실리콘을 분류하면 MILLABLE 실리콘고무(SOLID SILICONE RUBBER)와 액상실리콘고무(LIQUID SILICONE RUBBER)로 크게 나누어진다.If you look at the classification of silicone, silicone rubber should be heated according to the curing temperature to harden it. Although it is classified, liquid silicone rubber using an addition reaction has recently been commercialized, and thus silicone cannot be classified only by a conventional curing temperature. For this reason, silicon was classified according to the degree of polymerization or viscosity of the molomer, and thus the silicon is classified into MILLABLE SILICONE RUBBER and LIQUID SILICONE RUBBER.
본 발명에서도 액상실리콘 고무소재의 실리콘을 이용한 성형에 따른 제품의 성형방법을 개시하고자 하는데 있다.In the present invention, it is intended to disclose a method of forming a product according to the molding using a liquid silicone rubber material of silicon.
종래의 실리콘 제품의 사출성형은 실리콘소재에 따른 프레스 방법에 의하여고온경화용(HIGH TEMPERATURE VULCANIZING) 소재가 주로 이용되어 왔다. 이는 소정의 온도와 시간을 안배하여 소정의 물성상태를 이루는 실리콘 소재를 프레스로 사출처리 하여 제품화하였는바, 프레스 가공방식의 한계인 초정밀 제품을 요구하는 소재의 제품에서 경쟁력이 떨어지는 것이 흠이다.Conventional injection molding of silicone products has been mainly used for high temperature curing (HIGH TEMPERATURE VULCANIZING) by the press method according to the silicon material. This product is produced by injection-processing a silicon material that achieves a predetermined physical property state by arranging a predetermined temperature and time, and thus, it is not competitive in a product of a material requiring ultra-precision product, which is a limitation of the press processing method.
이를 위해 액상실리콘소재와 경화제를 혼합하여 사용하고 있지만, 혼합상태에서의 실린콘 소재가 사출장치로의 이송에 어려움이 있고, 사출되는 제품에서의 불량상태가 비교적 많이 나타나는 문제점이 있었다.To this end, the liquid silicone material and the curing agent are mixed and used, but the silicone material in the mixed state has difficulty in transferring to the injection apparatus, and there are relatively many defect states in the injected product.
가령, 혼합이 제대로 이루어지지 않은 실리콘 성형소재가 소정의 압으로 사출금형 내로 압송되는 상태에서 막힘 현상의 폐단으로 설비의 운휴가 잦고, 성형품에는 경화제를 적게 사용하였을 경우에 사출 후 성형된 제품이 서로 달라붙게 되는 폐단이 있었다.For example, when the silicone molding material that is not mixed properly is pumped into the injection mold at a predetermined pressure, the equipment is frequently shut down due to the clogging phenomenon, and the molded products are molded after injection when less hardener is used. There was a lung cling to.
본 발명은 종래의 문제점을 해결하기 위한 것으로, 실리콘 성형제품에 따른 경화시간을 단축하여 경화시간으로 인한 제품의 불량을 없앨 수 있도록 하는 반면에, 균일한 제품의 생산성을 향상시킬 수 있는 실리콘 성형제품 제조방법을 제공하는데 그 목적이 있다.The present invention is to solve the conventional problem, while reducing the curing time according to the silicone molded product to eliminate the defects of the product due to the curing time, while the silicone molded product that can improve the productivity of the uniform product The purpose is to provide a manufacturing method.
