Description
본 발명은 유기물에 공유결합으로 연결되는 산화방지제 및 그의 제조방법에 관한 것으로, 상세하게는 사슬의 어느 하나의 말단에 아지도 포르메이트기를 갖고 상기 사슬의 다른 하나의 말단에 페놀 유도체 잔기를 가짐으로써 분산성이 향상되고 휘발되지 않아 유기물의 안정성을 향상시켜주는 산화방지제 및 그의 제조방법에 관한 것이다.The present invention relates to an antioxidant covalently linked to an organic substance and a method for producing the same, and more particularly, by having an azido formate group at one end of a chain and a phenol derivative residue at the other end of the chain It relates to an antioxidant that has improved dispersibility and does not volatilize, thereby improving the stability of organic matter, and a method for preparing the same.
고분자는 열, 산소, 빛 등 외부 영향에 의해, 고분자 내 존재하는 결합이 절단되고 라디칼이 생성되는 산화반응이 일어난다. 이러한 반응으로 사슬 절단이나 가교가 일어나 착색 및 물성 저하 등 고분자 본질의 성질이 저하된다. 이에 산화방지제를 투입하여 가공 및 사용 중 원치 않는 화학적 반응을 억제하는 것이 일반적이다.Polymers undergo an oxidation reaction in which bonds existing in the polymer are cleaved and radicals are generated by external influences such as heat, oxygen, and light. As a result of this reaction, chain scission or crosslinking occurs, resulting in degradation of the intrinsic properties of the polymer, such as coloration and degradation of physical properties. It is common to add antioxidants to suppress unwanted chemical reactions during processing and use.
1차 산화방지제는 라디칼 포착제로 주로 페놀계와 방향족 아민계를 사용하고, 2차 산화방지제는 생성된 과산화물을 환원시키는 과산화물 분해제로 포스파이트 화합물과 유황 화합물이 대표적으로 사용되고 있다. 특히, 페놀계 산화방지제는 1차 산화방지제 중에서도 가격이 저렴할 뿐 아니라 라디칼을 소모시키는 효과가 뛰어나 산업현장에서 널리 사용되고 있다. 초기 색상 안정성이 우수하나, 과량이 투입되는 경우 대기와 반응으로 최종 제품을 변색시키는 경우가 많아, 종류에 따라 최적농도를 첨가해야한다.Primary antioxidants mainly use phenols and aromatic amines as radical scavengers, and phosphite compounds and sulfur compounds are typically used as secondary antioxidants as peroxide decomposers that reduce generated peroxides. In particular, phenolic antioxidants are inexpensive among primary antioxidants and are widely used in industrial fields because of their excellent effect of consuming radicals. It has excellent initial color stability, but when an excessive amount is added, it often discolors the final product due to reaction with the atmosphere, so it is necessary to add the optimum concentration according to the type.
현재도 많이 사용되는 mono-phenol을 가진 butylated hydroxy toluene(BHT)는 1차 산화방지제로 가격이 저렴하고 수지와 상용성 및 분산성이 좋아 우수한 산화 방지 성능을 나타낸다. 그러나 산화에 의한 quinone 구조로의 변형으로 변색이 쉽고, 분자량이 작기 때문에 휘발성이 커 사용기간이 짧은 단점을 지닌다. 그래서 높은 분자량의 산화방지제가 개발되었으나 수지와의 상용성이 떨어지는 또 다른 문제점이 대두되었으며, 이를 alkylation으로 보완하여 현재는 Irganox1010, Irganox1076 등을 가장 보편화하여 사용되고 있다. 그러나 이도 고온 가공 시 색 안정성이 떨어지는 문제를 가지고 있다.Butylated hydroxy toluene (BHT) with mono-phenol, which is widely used today, is a primary antioxidant that is inexpensive and exhibits excellent antioxidant performance due to its good compatibility and dispersibility with resins. However, it is easily discolored due to transformation into a quinone structure by oxidation, and has a short shelf life due to high volatility due to its small molecular weight. Therefore, high molecular weight antioxidants have been developed, but another problem of poor compatibility with resins has emerged, and this has been supplemented with alkylation, and currently Irganox 1010 and Irganox 1076 are most commonly used. However, this also has a problem of poor color stability during high-temperature processing.
따라서, 고분자 내 산화방지제의 휘발성을 줄이고 수지와의 상용성과 분산성을 유지할 수 있는 산화방지제 및 그의 제조방법에 관한 연구가 필요하다. Therefore, there is a need for research on antioxidants capable of reducing the volatility of antioxidants in polymers and maintaining compatibility and dispersibility with resins and their preparation methods.
본 발명의 목적은 상기 문제점들을 해결하기 위한 것으로, 고분자 내 산화방지제의 휘발성을 줄이고 수지와의 상용성과 분산성을 유지할 수 있는 산화방지제 및 그의 제조방법을 제공하는데 있다.An object of the present invention is to solve the above problems, and to provide an antioxidant capable of reducing the volatility of the antioxidant in a polymer and maintaining compatibility and dispersibility with a resin and a method for preparing the same.
또한, 본 발명의 산화방지제를 사용함으로써 열적 안정성이 향상된 고분자 및 그의 제조방법을 제공하는데 있다.In addition, it is to provide a polymer with improved thermal stability and a manufacturing method thereof by using the antioxidant of the present invention.
본 발명의 일 측면에 따르면, 사슬의 어느 하나의 말단에 아지도 포르메이트기()를 갖고 상기 사슬의 다른 하나의 말단에 페놀 유도체 잔기를 갖는 산화방지제가 제공된다.According to one aspect of the present invention, an azido formate group at either end of the chain ( ) and an antioxidant having a phenol derivative moiety at the other end of the chain.

In addition, the antioxidant may include 0.1 to 20 parts by weight based on 100 parts by weight of the sum of the polyolefin and the antioxidant. When the antioxidant is included in an amount of less than 0.1 parts by weight, the effect (polymer stability) caused by including the antioxidant is insignificant, which is undesirable. It is undesirable because it can degrade the properties.
또한, 상기 반응이 50 내지 300 ℃의 온도에서 수행되는 것일 수 있고, 바람직하게는 80 내지 250 ℃의 온도에서 수행될 수 있다. 상기 반응이 50 ℃ 미만의 온도에서 수행될 경우 산화방지제의 아지도 포르메이트기가 분해하지 않아 C-H 삽입 반응이 일어나지 않아 본 발명의 산화방지제가 폴리올레핀에 공유결합함으로써 발생하는 효과(분산성 및 안정성)가 나타나지 않아 바람직하지 않고, 300 ℃를 초과할 경우 폴리올레핀이 산화반응으로 분해변성되거나 아지도 포르메이트기의 분해가 빠르게 일어나 니트렌-니트렌 반응을 일으켜 반응에 참여하는 반응기 수가 줄어 온도 상승에 따른 효과가 미미하여 바람직하지 않다. In addition, the reaction may be carried out at a temperature of 50 to 300 °C, preferably at a temperature of 80 to 250 °C. When the reaction is carried out at a temperature of less than 50 ° C., the azido formate group of the antioxidant does not decompose and the C-H insertion reaction does not occur, so the effect (dispersibility and stability) caused by the covalent bonding of the antioxidant of the present invention to polyolefin When the temperature exceeds 300 ℃, polyolefin is decomposed and modified by oxidation reaction or azido formate group is rapidly decomposed, resulting in a nitrene-nitrene reaction, which reduces the number of reactors participating in the reaction, resulting in the effect of temperature rise. is insignificant and undesirable.
