Description
본 발명은 생분해도가 높고 잡초억제 기능 및 해충방지 기능이 있으며 기본적인 식물의 영양성분을 꾸준히 제공할 수 있는 농업용 멀칭비닐 제조방법에 관한 것으로 천연송진 및 님오일과 미생물 활성물 및 금속염으로 구성된 친환경적인 약품의 사용으로 토양의 산성화를 방지하고 식물류의 성장시 잡초억제 및 해충방지 효과가 있고 지속적인 영양성분의 공급을 통해 식물성장을 건강하게 유지시킬수 있는 해중방지 및 잡초억제 기능이 있고 비료성분이 함유된 생분해성 농업용 멀칭비닐 제조 방법에 관한 것이다.The present invention relates to a method of manufacturing agricultural mulching vinyl that is highly biodegradable, has weed suppression and pest prevention functions, and can consistently provide basic plant nutrients. It is an environmentally friendly material composed of natural resin, neem oil, microbial actives, and metal salts. It prevents acidification of the soil through the use of chemicals, has a weed-suppressing and pest-preventing effect when plants grow, has anti-seaming and weed-suppressing functions that can maintain healthy plant growth through the continuous supply of nutrients, and contains fertilizer ingredients. This relates to a method of manufacturing biodegradable agricultural mulching vinyl.
토양의 수분유지,보온성,냉해방지 및 강우에 의한 토실 유실방지등의 목적으로 사용되는 멀칭비닐의 수요는 잡초억제나 농약절감 및 인건비 절약이라는 큰 장점이 있는 반면 재활용이 어려워 대부분 사용후 대부분 불법 매립되거나 불법적으로 소각되어 심각한 오염원이 되어가는 실정이다. 년간 75만톤 정도 사용량중 수거율은 평균 비닐 수거율의 60%미만이며 특히 농촌의 여기저기에 방치된 검정색의 멀칭비닐은 거의 수거되지 않은 멀칭 비닐로 보면 된다.The demand for mulching vinyl, which is used for the purposes of maintaining moisture in the soil, maintaining warmth, preventing cold damage, and preventing soil loss due to rainfall, has great advantages in suppressing weeds, reducing pesticides, and saving labor costs, but it is difficult to recycle, so most of it is illegally buried after use. The situation is that it is being burned illegally or is becoming a serious source of pollution. Of the approximately 750,000 tons used annually, the collection rate is less than 60% of the average vinyl collection rate. In particular, the black mulching vinyl left here and there in rural areas can be viewed as almost uncollected mulching vinyl.
이러한 멀칭비닐의 장점을 살리고 폐기처리시의 문제점을 해결하기 위해 친환경적인 멀칭비닐의 개발이 시급한 상황이다.There is an urgent need to develop eco-friendly mulching vinyl to take advantage of its advantages and solve problems during disposal.
이러한 문제점들을 해결하기 위해 액상의 멀칭비닐이나 친환경 비닐 멀칭액들이 개발되어있지만To solve these problems, liquid mulching vinyl or eco-friendly vinyl mulching fluids have been developed.
비닐 멀칭제품에 비해 수분유지 기능이 약하고 특히 강우에 의한 토실유실 방지 기능이 없어 사용상의 제한이 따른다.Compared to vinyl mulching products, it has a weaker moisture retention function and does not have a function to prevent soil loss due to rainfall, so there are limitations in its use.
또한 생분해가 일어나는 멀칭비닐의 경우 사용단가가 높아 고소득 작물 이외에는 경제성이 적어 크게 보급되자 못하고 있는 실정이다.In addition, in the case of biodegradable mulching plastic, the unit cost of use is high, so it is not economically feasible for use except for high-income crops, so it is not widely distributed.
이러한 문제점으로 인해 멀칭비닐의 보온,수분유지,냉해방지,잡초억제 및 농약 절감등의 효과가 있는 일반적인 기능의 멀칭비닐이 대부분 사용되어지고 있는 실정이다. 이러한 멀칭비닐의 선행기술로는 대한민국 등록 특허 제 10-1378577호 "액상의 멀칭비닐용 성막조성물과 그 제조방법"(등록일자; 2014.03.19),대한민국 등록특허 제 10-1745452호 "인장강도가 개선된 자연분해 멀팅제" (등록일자 : 2017.06.02)과, 대한민국 등록특허 제10-2169864호 "친환경 비닐 멀칭액 조성물 및 그 제조방법"(등록일자: 2020.10.20) 등이 있다.멀칭비닐의 단점을 해결하기 위해 액상 조성물의 경우 PVA등을 피막형성제로 사용하여 분무후 토양에 폴리머 피막을 형성시켜 멀칭비닐의 효과를 대처하도록 고안 되어있으나 야외농작물에 사용시 강수에 의한 토실 유실방지 기능이 약하며 수분에 의한 취약성으로 뚜렷한 멀칭기능을 발휘하기가 어렵다. 또한 폴리머 피막층이 시간이 지남에 따라 토양하부로 내려가기 때문에 뿌리생육을 저하시켜 뿌리를 게 하는 단점을 지니고 있다.Due to these problems, mulching vinyl with general functions such as heat retention, moisture retention, cold prevention, weed suppression, and pesticide reduction is mostly used. Prior technologies for such mulching vinyl include Korea Registered Patent No. 10-1378577, “Liquid film-forming composition for mulching vinyl and its manufacturing method” (registration date; 2014.03.19), Korea Registered Patent No. 10-1745452, “Tensile strength “Improved Naturally Degradable Multing Agent” (registration date: 2017.06.02) and Republic of Korea Patent No. 10-2169864 “Eco-friendly vinyl mulching solution composition and method for manufacturing the same” (registration date: 2020.10.20), etc. Mulching Vinyl In order to solve the shortcomings, the liquid composition is designed to counter the effect of mulching vinyl by using PVA as a film forming agent to form a polymer film on the soil after spraying. However, when used for outdoor crops, the function of preventing soil loss due to precipitation is weak. It is difficult to exert a clear mulching function due to vulnerability to moisture. In addition, because the polymer film layer goes down to the bottom of the soil over time, it has the disadvantage of slowing down root growth and causing roots to grow thinner.
또한 천연섬유나 솜등에 수용성 PVA를 코팅한 멀칭제의 경우 인장력이 일반 0.02~0.035mm두계의 LDPE(Low Density Polyrthylene)수지로 제조된 멀칭비닐보다 두께가 높아 유연성이 떨어지며 생산과정과 원료선정에 많은 단계가 요구되며 생산성이 낮은 단점이 있다.In addition, in the case of mulching agents coated with water-soluble PVA on natural fibers or cotton, the tensile strength is higher than that of mulching vinyl made of LDPE (Low Density Polyrthylene) resin with a thickness of 0.02 to 0.035 mm, so it is less flexible and requires a lot of attention in the production process and raw material selection. It requires steps and has the disadvantage of low productivity.
또한 생분해성을 높인 멀칭비닐의경우 전부류를 사용한경우 물성 및 수분에 약해 실외 사용에 제한적이며 생분해 첨가제를 사용한 경우 산화생분해에 의해 생기는 미세 플라스틱에 의한 위험성을 내포하고 있는 것이 문제점으로 대두 되며 친환경소재인 PLA를 사용한경우 높은 원자재값으로 인해 경제성이 없는 단점을 지니고 있다.In addition, in the case of mulching vinyl with increased biodegradability, outdoor use is limited due to its weak physical properties and moisture when used with full current, and when biodegradable additives are used, it contains the risk of microplastics generated by oxidative biodegradation, which has emerged as a problem, making it an eco-friendly material. The use of PLA has the disadvantage of being economically unfeasible due to the high cost of raw materials.

It is characterized by consisting of an extrusion step of mixing and extruding vinyl. In addition, the mixing ratio of the raw materials used is 3 to 5 parts by weight of rosin, 1 to 3 parts by weight of neem oil, 10 to 20 parts by weight of molasses, 10 to 20 parts by weight of hydroxymethyl cellulose, and 10 to 10 to 20 parts by weight of xanthan gum per 1000 parts by weight of polyethylene resin. 20 parts by weight of manganese carbonate, 5 to 20 parts by weight, 10 to 20 parts by weight of corn starch, 3 to 5 parts by weight of calcium carbonate, 3 to 5 parts by weight of ammonium phosphate, and 3 to 5 parts by weight of potassium carbonate.

본 발명의 생분해성 멀칭비닐은 매립시 토양중에서 금속금속염이 폴리에틸렌수지의 분자크기를 4000~10000이하의 작은 분자 사슬로 산화분해(embrittleness)시키며 미생물에 의한 침식-소화-전환과정을 촉진 시키기위해 미생물의 성장을 촉진시키는 식품 첨가물 및 식물 추출물을 사용하여 미생물에 의한 생분해성을 높혔기 때문에 별도의 생분해성 폴리머 레진류의 사용없이 일반 폴리에틸렌 수지를 이용하여 멀칭비닐을 압출하여도 압출된 비닐속에 함유된 금속염과 식물 추출물 및 식품첨가물이 생분해성을 축진 시키며,식물성장의 필수 성분을 함유한 유기물을 첨가하여 식물의 발근과 성장을 건강하게 유지하며 천연 잡초억제기능과 해충방제기능이 있는 천연 식물 추출물을 사용하여 사용상의 편리성을 가지고 있고 사용원료의 단가가 저렴하여 경제적으로 다기능을 가진 친환경 멀칭 비닐을 제조 할 수 있다.The biodegradable mulching vinyl of the present invention oxidizes and decomposes the polyethylene resin into small molecular chains with a molecular size of 4,000 to 10,000 or less in the soil when landfilling, and uses microorganisms to promote the erosion-digestion-conversion process. Since biodegradability by microorganisms has been increased by using food additives and plant extracts that promote the growth of mulching vinyl, even if mulching vinyl is extruded using general polyethylene resin without the use of separate biodegradable polymer resins, the mulching vinyl contained in the extruded vinyl Metal salts, plant extracts, and food additives promote biodegradability, and organic substances containing essential ingredients for plant growth are added to maintain healthy rooting and growth of plants, and natural plant extracts with natural weed suppression and pest control functions are added.

첨부된 도면을 참조하여 본 발명의 멀칭비닐의 제조방법을 상세히 설명하고자 한다.The manufacturing method of the mulching vinyl of the present invention will be described in detail with reference to the attached drawings.
도 1에 도시된 바와 같이 본 발명의 해충방지 및 잡초억제 기능이 있고 비료성분이 함유된 생분해성 농업용 멀칭비닐 제조 방법은 약품을 선별 분쇄하는 제 1 분쇄 단계(A10), 상기 제 1 분쇄 단계에서 분쇄된 약품과 생분해성 소재를 혼합하는 제 2 혼합 단계(A20), 제 2의 혼합물을 레진 성형기에서 팰렛화 하는 제 3 레진 성형단계(A30), 제3의 레진성형단계에서 제조된 팰렛화된 레진을 폴리에틸렌 수지와 혼합하여 비닐성형기로 비닐을 압출하는 제4 비닐압출단계(A40)로 구성되어 있다.As shown in Figure 1, the method for producing biodegradable agricultural mulching vinyl containing pest prevention and weed suppression functions and fertilizer ingredients of the present invention includes a first pulverizing step (A10) of selectively pulverizing chemicals, and in the first pulverizing step, The second mixing step (A20), which mixes the pulverized medicine and the biodegradable material, the third resin molding step (A30), which pelletizes the second mixture in a resin molding machine, and the pelletized product produced in the third resin molding step. It consists of the fourth vinyl extrusion step (A40) in which resin is mixed with polyethylene resin and the vinyl is extruded using a vinyl molding machine.
또한 상기 사용원료의 혼합비는 폴리에틸렌 수지 1000중량부에 송진 3내지 5중량부, 님오일 1 내지 3 중량부, 당밀 10내지 20 중량부, 하이드록시메칠 셀루로즈 10내지 20중량부,잔탄검 10내지 20중량부 망간 카보네이트 5내지 20중량부, 옥수수전분 10내지 20중량부, 탄산칼슘 3내지 5중량부,,인산 암모늄 3내지 5중량부, 탄산칼륨 3내지 5 중량부로 구성 되어 있다.In addition, the mixing ratio of the raw materials used is 3 to 5 parts by weight of rosin, 1 to 3 parts by weight of neem oil, 10 to 20 parts by weight of molasses, 10 to 20 parts by weight of hydroxymethyl cellulose, and 10 to 10 to 20 parts by weight of xanthan gum per 1000 parts by weight of polyethylene resin. It consists of 20 parts by weight of manganese carbonate, 5 to 20 parts by weight, 10 to 20 parts by weight of corn starch, 3 to 5 parts by weight of calcium carbonate, 3 to 5 parts by weight of ammonium phosphate, and 3 to 5 parts by weight of potassium carbonate.
상기의 구성에 따른 해충방지 및 잡초억제 기능이 있고 비료성분이 함유된 생분해성 농업용 멀칭비닐 제조 방법의 과정은 다음과 같다.The process of manufacturing biodegradable agricultural mulching vinyl, which has pest prevention and weed suppression functions and contains fertilizer ingredients according to the above configuration, is as follows.
도 1에 도시된 바와 같이 제 1 분쇄단계(A10)는, 송진,하이드록시메칠 셀룰로즈,잔탄검,인산암모니움,탄산칼륨,탄산칼슘,옥수수전분을 고속분쇄기를 이용하여 150~200mesh크기로 고루 분쇄한다.As shown in Figure 1, in the first grinding step (A10), rosin, hydroxymethyl cellulose, xanthan gum, ammonium phosphate, potassium carbonate, calcium carbonate, and corn starch are evenly ground to a size of 150 to 200 mesh using a high-speed grinder. Crush.
제 2 혼합단계(A20)는 제1의 혼합물과 망간카보네이트를 혼합한다.The second mixing step (A20) mixes the first mixture and manganese carbonate.
제 3 레진 성형단계는 제2의 혼합물에 폴리에틸렌 수지와 님오일,당밀과 혼합하여 섭씨 130~150도에서 레진성형기를 이용하여 레진을 압출후 냉각수(섭씨 2~5도)를 20~30초간 통과 시켜 급냉후 커팅기를 이용하여 15~17pcs/g크기의 팰렛화 된 레진을 제조한다..The third resin molding step is to mix the second mixture with polyethylene resin, neem oil, and molasses, extrude the resin using a resin molding machine at 130 to 150 degrees Celsius, and pass coolant (2 to 5 degrees Celsius) for 20 to 30 seconds. After rapid cooling, use a cutting machine to produce pelletized resin with a size of 15~17pcs/g.
제4의 비닐 압출단계는 제3의 레진성형단계에서 제조된 레진과 폴리에틸렌 수지를 혼합하여The fourth vinyl extrusion step mixes the resin produced in the third resin molding step with polyethylene resin.
섭씨190~220도에서 비닐 압출기를 이용하여 해충방지 및 잡초억제 기능이 있고 비료성분이 함유된 생분해성 농업용 멀칭비닐을 0.03mm두께로 압출하여 제조한다.It is manufactured by extruding biodegradable agricultural mulching vinyl, which has pest prevention and weed suppression functions and contains fertilizer ingredients, to a thickness of 0.03 mm using a vinyl extruder at 190 to 220 degrees Celsius.
상기 송진은 천연 잡초 억제제로 잡초 억제력이 강하다 적정량 이상으로 사용시 비닐의 물성을 약화시킨다. 하이드록시메칠 셀룰로즈와 옥수수 전분, 당밀은 미생물의 침식-소화-전환과정을 촉진시켜 사용된 금속염에 의해 작은 분자 단위로 나누어진 폴리에틸렌의 생분해 과정을 촉진 시킨다. 적정량이하로 사용시 생분해 속도가 더디며 적정량이상을 사용시 멀칭비닐의 수분 투과율이 높아 비닐의 물성을 약화 시킨다. 잔탄검은 미생물의 먹이사슬에 이용되며 비닐의 인장력을 증진시키는 효과가 있다. 적정량이상 사용시 비닐 압출시 불균일한 두께의 비닐이 생산된다.The rosin is a natural weed suppressant and has strong weed-suppressing power. When used in more than an appropriate amount, it weakens the physical properties of vinyl. Hydroxymethyl cellulose, corn starch, and molasses promote the microbial erosion-digestion-conversion process and promote the biodegradation process of polyethylene, which is divided into small molecules by the metal salt used. When used in less than the appropriate amount, the biodegradation rate is slow, and when used in more than the appropriate amount, the moisture permeability of mulching vinyl is high, weakening the physical properties of the vinyl. Xanthan gum is used in the microbial food chain and has the effect of improving the tensile strength of vinyl. If more than the appropriate amount is used, vinyl of uneven thickness is produced during vinyl extrusion.
님오일은 해충방제효과가 뛰어난 정유로 해충방지기능에 사용되며 적정량이상 사용시 역한 냄새가 강하다. 망간 카보네이트는 폴리에틸렌수지의 분자크기를 4000~10000이하의 작은 분자 사슬로 산화분해(embrittleness)시키며 미생물에 의한 생분해 작용을 빠르게 진행시키는 기능이 있다. 적정량이하로 사용시 효과가 미미하며 적정량이상 사용시 비경제적이다. 탄산칼슘은 망간카보네이트의 산화분해작용을 촉진시키며 망간 카보네이트와의 5:1비율의 혼합이 가장 좋다.Neem oil is an essential oil with excellent pest control effects and is used to prevent pests. When used in excess of the appropriate amount, it has a strong unpleasant odor. Manganese carbonate has the function of oxidizing and decomposing polyethylene resin into small molecular chains with a molecular size of 4,000 to 10,000 or less and rapidly progressing biodegradation by microorganisms. When used in less than the appropriate amount, the effect is minimal, and when used in more than the appropriate amount, it is uneconomical. Calcium carbonate promotes the oxidation and decomposition of manganese carbonate, and mixing it with manganese carbonate in a 5:1 ratio is best.
인산암모늄,탄산칼륨은 식물성장에 기본이 되는 질소,인산,칼륨의 제공물질로 비닐의 수분투과율에 의한 수분수과시 토양으로 스며들어 식물이 성장을 촉진 시키는 기능이 있으나 적정량이상 사용시 과다사용으로 인한 식물의 성장에 역효과를 불러온다.Ammonium phosphate and potassium carbonate are substances that provide nitrogen, phosphoric acid, and potassium, which are the basis for plant growth. They permeate into the soil when moisture is absorbed due to the moisture permeability of vinyl and have the function of promoting plant growth. However, if used in more than the appropriate amount, excessive use may cause It has an adverse effect on plant growth.
본 발명에 의해 제조되는 멀칭비닐의 조성비에 따른 생화학분해율,잡초억제기능,해충방지기능,성장촉진기능을 측정하기 위해 다음과 같이 각각의 샘플을 제조하였다.In order to measure the biochemical decomposition rate, weed suppression function, pest prevention function, and growth promotion function of the mulching vinyl manufactured according to the present invention according to the composition ratio, each sample was prepared as follows.
