본 발명은 태양열 차단 성능이 향상된 농원예용 필름 조성물 및 이의 제조방법에 관한 것으로, 보다 구체적으로 실란(실레인, silane) 표면개질제를 이용하여 폴리에틸렌(polyethylene, PE) 수지와 혼합성을 높이고 필름의 투명성을 향상 시켜 원예 분야에 적용되기 적합한 가시광 및 적외선 투과율을 갖는 농원예용 필름 조성물 및 이의 제조방법에 관한 것이다.The present invention relates to an agricultural and horticultural film composition with improved solar heat blocking performance and a method for manufacturing the same, and more specifically, by using a silane (silane) surface modifier to increase mixing with polyethylene (PE) resin and to improve the transparency of the film. It relates to an agricultural and horticultural film composition having visible light and infrared transmittance suitable for application in the horticultural field by improving a film composition and a manufacturing method thereof.
식물의 성장을 촉진하는 방법으로서, 알루미늄 등의 금속막을 사용한 반사 시트, 백색광 반사 재료의 막을 사용해서 백색광을 반사하는 시트, 상기 반사 시트 상에 또한 반사 재료를 코팅한 시트 등을 사용하여, 토양 표면을 피복하는 방법이 알려져 있다. 한편, 토양을 보온하는 시트로서, 폴리에틸렌, 폴리염화비닐 등의 합성 수지 시트가 일반적으로 알려져 있다.As a method for promoting plant growth, a reflective sheet using a metal film such as aluminum, a sheet using a film of a white light reflective material to reflect white light, a sheet in which a reflective material is further coated on the reflective sheet, or the like is used, and the soil surface A method of covering is known. On the other hand, synthetic resin sheets such as polyethylene and polyvinyl chloride are generally known as sheets for keeping the soil warm.
그러나, 이러한 반사 재료를 코팅한 시트는, 지표에 도달하는 태양광선을 빠짐없이 반사하기 때문에, 식물의 성장은 촉진되지만, 열이 되는 적외광도 반사해버려, 온실 내 등에서 사용한 경우는, 당해 온실 내 등의 분위기의 기온이 상승해버리는 과제를 갖고 있다. 또한, 알루미늄 등의 금속막을 사용한 반사 시트는, 알루미늄 증착 가공을 실시하는 것이 일반적이어서, 이것에는 비용 상승 등의 문제가 있었다.However, since the sheet coated with such a reflective material reflects all the sunlight reaching the ground, plant growth is promoted, but it also reflects infrared light that becomes heat. When used in a greenhouse or the like, the greenhouse I have a problem that the temperature of the atmosphere on my back rises. In addition, it is common for a reflective sheet made of a metal film such as aluminum to be subjected to an aluminum vapor deposition process, which causes problems such as cost increase.
한편, 토양을 보온하는 합성 수지 시트는, 일반적으로 적외선의 투과율이 높기 때문에, 토양의 보온 효과가 충분하지 않았다.On the other hand, since the synthetic resin sheet for keeping the soil warm generally has a high infrared transmittance, the effect of keeping the soil warm is not sufficient.
따라서, 전술한 문제점을 보완하기 위해 본 발명가들은 농원예 분야에 적용되기 적합한 가시광 및 적외선 투과율을 갖는 필름 조성물에 대한 개발이 시급하다 인식하여, 본 발명을 완성하였다.Therefore, in order to compensate for the above problems, the inventors of the present invention recognized the urgent need to develop a film composition having visible light and infrared transmittance suitable for use in agricultural and horticultural fields, and completed the present invention.
본 발명의 목적은 실란(실레인, silane) 분산제를 이용하여 폴리에틸렌(polyethylene, PE) 수지와 혼합성을 높이고 필름의 분산성 및 투명성을 향상시켜 원예 분야에 적용되기 적합한 가시광 및 적외선 투과율을 갖는 농원예용 필름 조성물 및 이의 제조방법을 제공하는 것이다.An object of the present invention is to use a silane (silane) dispersant to improve mixing with polyethylene (PE) resin and to improve the dispersibility and transparency of a film, so that farms having visible light and infrared transmittance suitable for application to the horticultural field. It is to provide an example film composition and a manufacturing method thereof.
