Description
본 발명은 플라스틱 분해 촉진용 첨가제 조성물에 관한 것으로서, 보다 상세하게는 다양한 종류의 플라스틱 원료를 사용하여 제조되는 1회용 플라스틱용기나 비닐 포장용기 등의 플라스틱 제품이 빠른 시간 내에 분해될 수 있도록 도와주는 플라스틱 분해 촉진용 첨가제 조성물에 관한 것이다. The present invention relates to an additive composition for promoting plastic decomposition, and more particularly, to help plastic products such as disposable plastic containers or plastic packaging containers manufactured using various kinds of plastic raw materials to be quickly decomposed. It relates to an additive composition for promoting decomposition.
근래에 들어 폴리에틸렌이나 폴리프로필렌 등의 각종 플라스틱 올레핀계수지를 이용하여 제조된 각종 쇼핑백이나 폐비닐, 플라스틱 포장용기 또는 1회용 용기 등에 대한 수요가 급격하게 증가되면서 그에 따른 폐기물 발생량 또한 급속하게 증가되고 있다. In recent years, the demand for various shopping bags, waste vinyl, plastic packaging containers or disposable containers manufactured using various plastic olefin resins such as polyethylene and polypropylene has been rapidly increasing, and the amount of wastes generated is rapidly increasing.
현재 대부분의 플라스틱 폐기물은 소각하거나 매립하는 방법을 적용하여 처리하고 있는데, 이러한 처리방법은 환경호르몬 누출, 맹독성의 다이옥신 검출 폐기물의 불완전 연소에 의한 대기오염 발생 등과 같은 심각한 환경오염의 원인으로 대두되고 있다. 이러한 문제점을 해결하기 위하여 사용 후 광이나 토양중의 미생물에 의해 분해되는 환경 친화적이고 무해한 분해성 플라스틱의 개발의 필요성이 대두되고 있다. Currently, most plastic wastes are disposed of by incineration or landfill, which is a cause of serious environmental pollution such as environmental hormone leakage and air pollution caused by incomplete combustion of toxic dioxin-detecting wastes. . In order to solve this problem, there is a need to develop an environmentally friendly and harmless degradable plastic that is decomposed by microorganisms in light or soil after use.
분해성 플라스틱은 크게 토양, 수중 등의 자연환경에서 미생물에 의해서 분해되는 생분해성 플라스틱, 태양광에 의해서 분해되는 광분해성 플라스틱, 첨가제인 분해물질을 범용 플라스틱에 첨가하여 만든 생붕괴성 플라스틱 및 이들의 특성을 혼합한 생, 광분해성 플라스틱 등으로 구분되고 있다. Degradable plastics are largely biodegradable plastics decomposed by microorganisms in natural environments such as soil and water, photodegradable plastics decomposed by sunlight, and biodegradable plastics made by adding additives, which are additives, to general purpose plastics. It is divided into bio, photodegradable plastics and the like.
기존의 분해성 플라스틱은 대체로 옥수수 및 감자 전분을 이용하거나 지방족 폴리에스테르를 사용해서 만들었다. 지방족 폴리에스테르는 분해성이 없는 방향족 폴리에스테르의 분자 구조 중 벤젠고리 부분을 탄화수소로 대체하여 자연환경에서 분해가 가능하도록 만든 것이다. Traditional degradable plastics are usually made from corn and potato starch or from aliphatic polyesters. Aliphatic polyesters are hydrocarbons that replace the benzene ring in the molecular structure of non-degradable aromatic polyesters so that they can be degraded in the natural environment.
그러나 상기한 전분이나 지방족 폴리에스테르를 사용하여 제조되는 분해성 플라스틱을 포함하여 종래 대부분의 분해성 플라스틱은 분해속도의 조절이 용이하지 못할 뿐만 아니라 분해속도가 느리고 특히, 적용되는 플라스틱의 재료가 극히 제한적이라는 단점이 있다. However, most of the conventional degradable plastics, including the degradable plastics prepared using the starch or aliphatic polyester, are not easy to control the rate of decomposition, but also have a low rate of decomposition, and in particular, the material of the applied plastic is extremely limited. There is this.
이에 본 발명은 상기한 종래의 문제점을 해결하기 위한 것으로 다양한 종류의 플라스틱 원료를 사용하여 제조되는 1회용 플라스틱용기나 비닐 포장용기 등의 플라스틱 제품이 빠른 시간 내에 분해될 수 있도록 함과 동시에 분해시간의 조절이 가능한 플라스틱 분해 촉진용 첨가제 조성물을 제공하는데 그 목적이 있다. Accordingly, the present invention is to solve the above-mentioned problems of the present invention so that plastic products such as disposable plastic containers or plastic packaging containers manufactured using various kinds of plastic raw materials can be decomposed quickly and at the same time. It is an object of the present invention to provide an additive composition for promoting plastic decomposition that can be controlled.
상기한 목적을 달성하기 위하여 본 발명은 플라스틱 분해 촉진용 첨가제 조성물에 있어서, 총 조성물 100중량부를 기준으로 탄산칼슘 70∼80중량부와, 폴리프로필렌 10∼20중량부, 56∼60% 파라핀액 2∼4중량부, 스테아린산 1∼2중량부 및 자체분해능을 갖는 고분자물질 3∼5중량부를 포함함을 특징으로 하는 플라스틱 분해 촉진용 첨가제 조성물을 제공한다. In order to achieve the above object, the present invention, in the additive composition for promoting plastic decomposition, 70 to 80 parts by weight of calcium carbonate, 10 to 20 parts by weight of polypropylene, 56 to 60% paraffin solution 2 based on 100 parts by weight of the total composition. It provides an additive composition for promoting plastic decomposition, characterized in that it comprises-4 parts by weight, 1 to 2 parts by weight of stearic acid and 3 to 5 parts by weight of a polymer material having self-degradation.
또한 본 발명은 상기 조성물을 플라스틱 원료에 첨가하여 제조된 것을 특징으로 하는 분해성 플라스틱 제품을 제공한다. The present invention also provides a degradable plastic product, characterized in that prepared by adding the composition to a plastic raw material.
이하 본 발명을 보다 상세하게 설명하면 다음과 같다. Hereinafter, the present invention will be described in more detail.
본 발명에 따른 플라스틱 분해 촉진용 첨가제 조성물은 총 조성물 100중량부를 기준으로 탄산칼슘 70∼80중량부와, 폴리프로필렌 10∼20중량부, 56∼60% 파라핀액 2∼4중량부, 스테아린산 1∼2중량부 및 자체분해능을 갖는 고분자물질 3∼5중량부로 이루어진다. The additive composition for promoting plastic decomposition according to the present invention is 70 to 80 parts by weight of calcium carbonate, 10 to 20 parts by weight of polypropylene, 2 to 4 parts by weight of 56 to 60% paraffin solution, and 1 to stearic acid based on 100 parts by weight of the total composition. It consists of 2 to 5 parts by weight and 3 to 5 parts by weight of a polymer material having self-degradation.
탄산칼슘은 주위 수분과 서서히 반응하면서 플라스틱이 산화 분해되는 과정에서 산소와의 접촉면적을 증가시켜 플라스틱의 분해시간을 단축시킬 목적으로 첨가하게 된다. 이때, 탄산칼슘의 첨가량이 총 조성물 100중량부에 대하여 70중량부 미만으로 첨가될 경우 폐 플라스틱 제품의 분해시간이 지연되는 문제점이 있으며, 그 첨가량이 80중량부를 초과할 경우 플라스틱 제품의 내구성이 저하되는 문제점이 있을 뿐만 아니라 상대적으로 바인더 역할을 하는 수지의 첨가량이 적어 조성물을 펠릿화하는 작업이 용이하지 않다는 문제점이 있다. 따라서 상기 범위 내에서 탄산칼슘을 첨가하는 것이 바람직하다. Calcium carbonate is added for the purpose of shortening the decomposition time of the plastic by increasing the contact area with oxygen in the process of oxidative decomposition of the plastic while slowly reacting with the ambient moisture. At this time, when the addition amount of calcium carbonate is added less than 70 parts by weight based on 100 parts by weight of the total composition, there is a problem that the decomposition time of the waste plastic product is delayed, and when the addition amount exceeds 80 parts by weight, the durability of the plastic product is lowered Not only is there a problem in that the addition of a relatively small amount of the resin to act as a binder is not easy to pelletize the composition. Therefore, it is preferable to add calcium carbonate within the above range.
폴리프로필렌은 바인더 역할을 하는 것으로서 조성물의 결합력을 증진시켜 펠릿화를 가능하게 하는 것으로서, 그 첨가량이 총조성물 100중량부에 대하여 10중량부 미만으로 첨가될 경우 조성물의 결합력이 약해져 펠릿화 작업이 용이하지 못하다는 문제점이 있으며, 그 첨가량이 20중량부를 초과할 경우 상대적으로 플라스틱분해를 촉진시키는 탄산칼슘 등의 첨가량이 적어 폐 플라스틱 제품의 분해 시간을 지연시키는 문제점이 있으므로 상기범위 내에서 폴리프로필렌을 첨가하는 것이 좋다.Polypropylene acts as a binder to enhance the bonding strength of the composition to enable pelletization, when the addition amount is less than 10 parts by weight based on 100 parts by weight of the total composition of the composition becomes weak and easy to pelletize operation If the addition amount exceeds 20 parts by weight, there is a problem that delays the decomposition time of the waste plastic product due to the relatively small amount of calcium carbonate, which promotes plastic decomposition, so that polypropylene is added within the above range. Good to do.
본 발명에서는 활제로서 파라핀액을 첨가하였으며, 파라핀액은 본 발명에 따른 조성물을 펠릿화하는 과정에서 토출기에서의 흐름성을 향상시키게 된다. 본 발명에서는 56∼60%의 파라핀액을 총조성물 100중량부에 대하여 2∼4중량부 첨가하였다. In the present invention, a paraffin solution is added as a lubricant, and the paraffin solution improves the flowability in the ejector in the process of pelletizing the composition according to the present invention. In the present invention, 2 to 4 parts by weight of paraffin solution of 56 to 60% was added to 100 parts by weight of the total composition.
스테아린산은 불포화기를 함유하고 있어 자동적으로 산화되어 폐 플라스틱 제품의 초기 분해를 촉진시키는 역할을 하며, 그 첨가량이 총조성물 100중량부에 대하여 1중량부 미만으로 첨가될 경우 폐 플라스틱 제품의 분해시간이 지연되는 문제점이 있으며, 그 첨가량이 2중량부를 초과할 경우 플라스틱 제품의 내구성이 저하되는 문제점이 있다. 따라서, 상기 범위 내에서 스테아린산을 첨가하는 것이 바람직하다. Stearic acid contains unsaturated groups, which are automatically oxidized to promote the early decomposition of waste plastic products, and the decomposition time of waste plastic products is delayed when the amount is added less than 1 part by weight based on 100 parts by weight of the total composition. There is a problem that, if the addition amount exceeds 2 parts by weight there is a problem that the durability of the plastic product is lowered. Therefore, it is preferable to add stearic acid within the said range.
자체분해능을 갖는 고분자물질은 플라스틱 제품의 스테아린산에 의한 초기분해 이후 중간 분해를 지속적으로 유지시킬 목적으로 첨가하는 것으로서, 통상의 전분계 고분자나 셀룰로오스계 고분자 및 기타 공지의 합성 고분자 등을 사용할 수 있다. 예를 들어 전분계 고분자로는 옥수수 전분, 밀가루 전분, 감자 전분, 쌀 전분에서 선택되는 것을 사용할 수 있으며, 셀룰로오스계 고분자로는 셀룰로오스 또는 셀룰로오스 유도체를 사용할 수 있다. The polymer material having self-degradation is added for the purpose of continuously maintaining intermediate decomposition after initial decomposition by stearic acid of a plastic product, and may use conventional starch-based polymers, cellulose-based polymers, and other known synthetic polymers. For example, the starch-based polymer may be selected from corn starch, wheat flour starch, potato starch, rice starch, the cellulose polymer may be used a cellulose or a cellulose derivative.
상기 자체분해능을 갖는 고분자물질은 총 조성물 100중량부에 대하여 그 첨가량이 3중량부 미만으로 첨가될 경우 폐 플라스틱 제품의 분해시간이 지연되는 문제점이 있으며, 그 첨가량이 5중량부를 초과할 경우 플라스틱 제품의 내구성이 저하되는 문제점이 있으므로, 상기 범위 내에서 자체분해능을 갖는 고분자물질을 첨가하는 것이 좋다. The polymer material having the self-degradation has a problem that the decomposition time of the waste plastic product is delayed when the addition amount is less than 3 parts by weight based on 100 parts by weight of the total composition, and when the addition amount exceeds 5 parts by weight, the plastic product Since there is a problem that the durability of the degradation, it is good to add a polymer material having a self-degradation within the above range.
전술한 구성을 갖는 조성물은 통상의 용융 압출 성형과정을 통해 2∼10mm의 크기를 갖는 펠릿으로 만들어 사용하게 되는데, 펠릿화는 통상의 방법을 적용하여 용이하게 제조할 수 있다. The composition having the above-described configuration is used to make a pellet having a size of 2 to 10mm through a conventional melt extrusion process, pelletization can be easily prepared by applying a conventional method.
제조된 펠릿은 각종 쇼핑백이나 폐비닐, 플라스틱 포장용기 또는 1회용 용기 등의 플라스틱 제품을 제조하는 과정에서 첨가할 수 있으며, 이와 같이 하여 제조된 플라스틱 제품은 분해가 촉진되어 빠른 시간 내에 분해되게 된다. The manufactured pellets can be added in the process of manufacturing plastic products such as various shopping bags, waste vinyl, plastic packaging containers, or disposable containers, and the plastic products thus produced are accelerated to be decomposed and quickly decomposed.
적용 가능한 플라스틱 제품의 원료로는 통상의 사용되는 것으로서 폴리에틸렌이나 폴리프로필렌, 폴리비닐클로라이드, ABS수지 또는 폴리스틸렌에서 선택되는 것을 사용할 수 있으며, 이외에도 다양한 종류의 플라스틱 원료에 적용할 수 있다. As a raw material of the applicable plastic product, one selected from polyethylene, polypropylene, polyvinyl chloride, ABS resin, or polystyrene may be used, and it may be applied to various kinds of plastic raw materials.
이때, 상기한 원료들을 사용하여 플라스틱제품을 제조하는 과정에서 그 첨가량을 조절하면 최종적으로 제조된 플라스틱 제품의 분해시간을 자유롭게 조절할 수 있으며, 예를 들어 반복 사용하는 플라스틱 제품의 경우에는 소량 첨가하여 분해시간을 장시간에 걸쳐 분해될 수 있도록 하는 것이 좋고, 1회용 용기 등과 같이 한번 사용하고 폐기되는 플라스틱제품에는 과량을 사용하여 분해시간이 단축될 수 있도록 하는 것이 좋다. At this time, by adjusting the amount of addition in the process of manufacturing a plastic product using the above raw materials can be freely adjusted the decomposition time of the finally produced plastic product, for example, in the case of repeated use of plastic products by adding a small amount of decomposition It is good to allow time to be decomposed over a long time, and it is good to use an excess amount of plastic products that are used once and disposed of, such as a disposable container, so that the decomposition time can be shortened.
상기에서 설명한 바와 같이 본 발명에 따른 프라스틱 분해 촉진용 첨가제 조성물의 경우 다양한 종류의 플라스틱 원료를 사용하여 제조되는 1회용 플라스틱용기나 비닐 포장용기 등의 플라스틱 제품을 제조하는 과정에서 첨가될 수 있으며, 이와 같이 하여 제조된 플라스틱 제품은 빠른 시간 내에 분해될 수 있을 뿐만 아니라 첨가제 조성물의 첨가량 조절을 통해 폐 플라스틱 제품의 분해시간을 용이하게 조절할 수 있게 된다. As described above, the additive composition for promoting plastic decomposition according to the present invention may be added in the process of manufacturing a plastic product such as a disposable plastic container or a plastic packaging container manufactured using various kinds of plastic raw materials. The plastic product thus manufactured can be decomposed in a short time and can easily control the decomposition time of the waste plastic product by controlling the addition amount of the additive composition.
