발명의명칭 :식물정유를포함하는방충농자재 기술분야
[1] 본발명은식물정유를포함하는방충농자재및해충기피매트에관한것으로, 더욱상세하게는해충기피성분이포함된식물성정유를이용하여해충기피 효과가있는칩을제조하고,이를이용하여비닐,트레이또는과일포장지,용기 등곤충이나해충이기피하여방충효과를가질수있는농업용농자재및매트 등의방충성플라스틱계복합자재에관한것이다.
배경기술
[2] 최근건강한생활수준의향상을위한국민들의관심과기호성이향상되면서 농약이나몸에해로운약제를사용하지않은친환경농산물에대한소비자들의 기호와요구가증가하는추세에있다.
[3] 특히 2019년 1월 1일부터시행되는 PLS(Positive List System)제도의규제
때문에허가된품목의농약을사용하지않거나미허가농약이농산물에잔류시 엄격한처벌조항이있어서농사를짓는농민들이나유통업자들에게는여러 가지측면에서부담이될수밖에없다.
[4] 이에각종농산물을안전하게생산하고자하는농민과안전한먹거리를
생산하는것을감독하는정부당국으로서는앞으로친환경농산물생산에대한 사고방식을일신해야할필요가있다.
[5] 농업은잡초방제와해충과의전쟁이라고할수있는데,지금까지는농약의
독성을고려하지않고대량생산으로농민의이익을가져올수있는방법론에만 몰두한농업이었다고할것이다.이제는안전한농산물의생산부터농산물의 포장및수송에이르기까지안전하게소비자에게전달될수있도록다방면에 걸쳐서노력해야만할것이다.
[6] 농산물생산에 있어서해충의피해를구제하기위한다양한방안이
고려되었으며,그중하나가해충기피방충플라스틱계수지제품이다.해충이 싫어하는식물성정유를함유시킨방중비닐을사용하는경우,농약을사용하지 않거나안전성이검증된저농약을살포함으로써해충으로부터안전한농산물을 생산할수있는이점이있다.
[7] 식물성정유의배출을서서히하게만드는것은기존의잘알려진서방성
마이크로캡슐을이용함으로써가능하며농산물의생산이약 3개월의
생육주기를생각할경우,복합화된플라스틱계비닐소재의식물성정유의 서방성특성으로인하여효과적인해충구제법의하나로알려져 있다.
[8] 그러나일반적으로정유와같은해충기피제가수지와상용성이없어방충제의 분산이매우어렵기때문에,마이크로캡슐이나정유의적절한분산을위해 다공성플라스틱펠렛을이용하여방충마스터배치칩을만들고,이것을수지와 건식으로혼합하여필름을성형하는방법이알려져있다.
[9] 현재항충비닐에대한기존의등록특허 W-1886020호 (항충비닐의제조방법및 이에의해제조된항충비닐)에서는인체에유해한독성농약들을사용하고 있어서농산물과농부들의안전성이검증되지못하고있는문제점이있다.

상기마스터 배치와,식물정유및흡유성분말을혼합하여교반하는단계;를 포함하는해충기피용칩제조방법을제공한다.
[77]
본발명의 일실시예에따르면,본발명의해충기피용칩 제조방법에 있어서, 상기식물정유는유화제와혼합하여 0.1내지 10.0중량%의농도로물에 희석한
7 7 76781 것일수있다.바람직하게는 0.2내지 5.0중량%,보다바람직하게는 0.2내지 1.0 중량%,보다더바람직하게는 0.3내지 0.5중량%의농도로물에 희석한것일수 있다.

80] 본발명의 해충기피용칩제조방법에 이용되는흡유성분말은,다공성무기 분말로서 ,점토 (clay),운모 (mica),몬모리로나이트 (montoiorillonite),
카오리나이트 (kaolinite),할로이사이트 (halloysite),파이로필라이트 (pyrophyllite), 일라이트 (illite),벤토나이트 (bentonite),석분 (stone flour)또는활석 (talc)으로부터 선택하여사용할수있다.상기석분 (돌가루)의경우,다른다공성무기분말재료 대비 경제적인면에서유리한효과가있다.본발명의 일실시예에서사용한 규조토 (diatomite)는탈취 및탈수및흡착의효과를지닌무독성의 천연재료로서 물리적 형태로해충을방제할수있는데，특히 ,본발명에서는기공을통해식물 정유를흡착 (흡수)한후서서히지속적으로방출되는서방성방출효과를 부여한다.본발명의해충기피용칩 제조에는상기 언급된다공성무기분말중 어떤것이든이용할수있으나,석분또는규조토를이용하는것이바람직하며 , 식물정유는유상이며점도가높으므로마스터칩 (해충기피용칩)의플라스틱 수지와복합화가용이한규조토를이용하는것이더욱바람직하다.
[81] 본발명의일실시예에따르면,본발명의해충기피용칩제조방법에있어서, 상기흡유성분말은,평균크기 0.1내지 W0 //II1이고평균기공크기가 0.01내지 인규조토분말 100중량부에대하여 ,메틸셀룰로오스또는녹말을 10내지 50중량부로혼합한후건조시켜제조되는것일수있다.또한,상기흡유성 분말에식물정유를흡수시킨것일수있다.
[82]
[83] 본발명의일실시예에서해충기피용칩은해충기피효과를가진농자재
제조를위한것이설명된다.해충기피용칩제조방법은마스터배치를제조하는 단계;및상기마스터배치와식물정유를혼합하여용융시키고,규조토분말을 첨가하여교반한후,냉각및절단시켜칩을제조하는단계를포함하여 구성되는것일수있다.
[84] 상기마스터배치를제조하는단계는플라스틱소재로서
쓸리프로필렌 (PolyProphlene),쓸리에틸렌 (PolyE比 lylene)및 EVA (Ethylene Vinyl Acetate Copolymer)를용융시킨후,냉각및절단하여제조하는단계이다.
[85] 본발명에서폴리프로필렌，폴리에틸렌및 EVA수지는각각폴리프로필렌 20 내지 40중량부,폴리에틸렌 40내지 60중량부및 EVA수지 10내지 20중량부의 중량비율로혼합된다.이후,상기폴리프로필렌,폴리에틸렌및 EVA수지를 압출기에투입하여 EVA수지가용융될수있도록 100내지 250OC의온도, 바람직하게는 150내지 250OC의온도,보다더바람직하게는 200내지 250OC의 온도로가열한후,마스터배치를제조할수있다.이렇게제조된마스터배치는 후행되는식물정유와규조토분말과혼합하여해충기피용칩을제조하기위해 냉각기에서 50내지 70OC온도로냉각시켜 0.1내지 Wmm크기로절단하여 제조한다.
[86] 이후,마스터배치를이용하여해충기피용칩을제조할수있으며,마스터 배치와식물정유를혼합하여용융시켜교반시킨다.규조토분말을첨가하여 교반하여혼합되도록한다.용융된혼합물은냉각기에서 50내지 70OC로냉각 시킨후절단하여해충기피용칩을제조한다.
[87] 상기에서제조된해충기피용칩은통상적인사출성형기서플라스틱재료와 용해시켜비닐,트레이등농자재로성형시켜제조될수있다.
[88] 상기와같이해충기피용칩을이용한방충비닐과식물재배용트레이등의 농자재를제조하는공정은일반적으로알려진제조공정으로구현가능하므로 구체적인설명은생략하도록한다.
[89] 또한,본발명의일실시예에따르면식물정유를비닐,트레이 ,노끈,차양막, 포장지,용기등의형태로압출성형되는소재의표면에함침되는것이 설명된다.식물정유를소재의표면에함침되는경우에는필름,포장지,용기 등의형태로압출하여성형된소재에식물정유를자체로소재표면에 분사하거나,식물정유를포함하는정유잉크조성물을소재표면에분사또는 인쇄될수있다.여기서정유잉크는예를들어수지,첨가제및유기용제와 혼합하여제조할수있으며，이러한경우식물정유를수지와유기용제에넣고 수지가용제에완전히용해되도록한후,첨가제와혼합하여제조할수있다. 여기서첨가제는본발명에서설명된흡유성분말또는항균,항충성분을 이용할수있고,또분산제,가소제,계면활성제,접착보강제,브로킹방지제 또는안료를이용할수있으며,유기용제로서케톤,에스테르,알콜또는 글리콜에테르중에하나이상을선택하여이용할수있으나,이에제한되는것은 아니다.
[9이 본발명에서소재의표면에함침시키는경우에는소재의표면에식물정유 또는잉크조성물이부착이용이하도록열처리하는것이바람직하며,이때, 열처리온도는식물정유의성질변화를최소활할수있도록 70내지 150OC의 온도에서이루어지는것이바람직하다.열처리온도가 70OC미만이면식물정유 및정유잉크건조와접착이불충분하여쉽게박리되는경우가발생할수 있으며, 15(TC를초과하는경우에는식물정유의방충성질이변질하여 방충효과가떨어지는문제점이 있으므로본발명의열처리온도내에서 구현되는것이바람직하다.
[91] 본발명에서는식물정유의서방성방출효과를위해필름소재에식물정유나 정유잉크를코팅하는경우에는접착제를혼합하여적어도 2이상의필름 사이에도포할수있다.예를들어필름소재의경우에는필름의일면에식물 정유나정유잉크를도포한후건조후드나열처리를통해용제를증발시킨후, 접합할필름을가열압착하여제조될수있다.이러한 2장이상의필름소재 사이에식물정유가도포되는경우실시양태상에서식물정유가천천히 지속적으로방출되게됨으로서방충효과의유지가용이하도록하기위함이다.
