Description
본 발명은 반응성과 용해력 및 희석력이 우수한 유기 액상안정제 제조용 용제 조성물에 관한 것이다. The present invention relates to a solvent composition for preparing an organic liquid stabilizer having excellent reactivity, solubility, and dilution.
플라스틱에 사용하는 유기 액상안정제는 무기금속과 유기물을 반응시켜 금속염 화합물로서 제조된다. 유기 액상안정제는 제조시에 주로 경유나 등유 등 지방족 탄화수소계 용제를 사용하는데, 이때에 지방족 탄화수소계 용제의 광범위한 증발속도로 인하여, 반응속도가 적절하지 않게 되어, 유기 액상안정제의 제조 수율이 낮은 문제점이 있다. 또한, 금속염의 구성성분에 따라 침전물이 침강되기도 하고, 장기 보관 중에 금속염으로 구성된 유기 액상안정제가 응고하거나 경화되어 저장 기간이 더욱 단축되는 단점이 있다. 이와 같이, 유기 액상안정제 품질의 효율이 떨어지는 현상의 주요한 원인 중 하나는 유기 액상안정제의 제조시에 사용되는 용제에 기인하는 것이다. Organic liquid stabilizers used in plastics are prepared as metal salt compounds by reacting inorganic metals with organic substances. The organic liquid stabilizer mainly uses aliphatic hydrocarbon solvents such as light oil and kerosene in the manufacture, but due to the wide evaporation rate of the aliphatic hydrocarbon solvent, the reaction rate is not appropriate, and the yield of the organic liquid stabilizer is low. There is this. In addition, the sediment may be settled depending on the constituents of the metal salt, and the organic liquid stabilizer composed of the metal salt solidifies or hardens during long term storage, thereby shortening the storage period. As such, one of the main causes of the deterioration of the efficiency of the organic liquid stabilizer is due to the solvent used in the preparation of the organic liquid stabilizer.
상기와 같이, 유기 액상안정제 제조용 용제로서 경유와 등유 등 지방족 탄화수소계 용제를 사용하는 종래의 기술은 용제로서 사용되는 지방족 탄화수소계 용제 의 증발온도가 일정하지 않아, 반응성과 수율에 문제점을 야기할 수 있으며, 균일성이 저하되는 문제점이 있었다.As described above, the conventional technique using an aliphatic hydrocarbon solvent such as light oil and kerosene as a solvent for preparing the organic liquid stabilizer is not constant the evaporation temperature of the aliphatic hydrocarbon solvent used as the solvent, may cause problems in reactivity and yield. And there was a problem that the uniformity is lowered.
따라서, 유기 액상안정제의 제조시에 금속염의 반응온도가 약 110~130℃이기 때문에, 이러한 반응온도에서 안정할 수 있도록 증발온도가 약 150℃ 이상이고, 또한 금속염의 점도를 조절할 수 있는 용해력 및 희석력이 우수한 용제가 요구된다. 또한 유기 액상안정제의 보관시 구성성분인 금속염과 용제의 분리가 일어나지 않도록 일정하고 특정한 비중을 갖는 용제가 요구된다. Therefore, since the reaction temperature of the metal salt is about 110-130 ° C. in the preparation of the organic liquid stabilizer, the evaporation temperature is about 150 ° C. or higher so as to be stable at this reaction temperature, and the solvent power and dilution that can adjust the viscosity of the metal salt. Good solvents are required. In addition, a solvent having a specific and specific specific gravity is required to prevent separation of the metal salt and the solvent, which are components in the storage of the organic liquid stabilizer.
본 발명의 목적은 상기와 같은 종래기술의 문제점을 개선하기 위한 것으로서, 유기 액상안정제의 품질강화를 위하여, 유기 액상안정제 제조시 지방족 탄화수소계 용제에 방향족 탄화수소계 용제를 혼합하여 사용하므로써 유기 액상안정제의 제조시에는 반응성과 용해력 및 희석력을 높이고, 보관시에는 금속염과 용제의 분리를 방지할 수 있는, 유기 액상안정제 제조용 용제 조성물을 제공하는 것이다.An object of the present invention is to improve the problems of the prior art as described above, in order to enhance the quality of the organic liquid stabilizer, the organic liquid stabilizer by mixing an aromatic hydrocarbon solvent with an aliphatic hydrocarbon solvent when preparing the organic liquid stabilizer It is to provide a solvent composition for producing an organic liquid stabilizer that can increase the reactivity, solubility and dilution at the time of manufacture, and prevent the separation of the metal salt and the solvent at the time of storage.

In addition, the organic liquid stabilizer prepared in Example, no precipitation was observed even after standing for 120 hours. Therefore, when the solvent composition for preparing the organic liquid stabilizer of the present invention is used, there is an advantage that it is possible to maintain a uniform quality without being precipitated even during the manufacture of the organic liquid stabilizer and long-term storage.
