Abstract
This utility model discloses a double color polyethylene farmland film, which consists of a silver gray outer film layer or a white outer film layer and a black inner film layer. The silver gray outer film layer or the white outer film layer and the black inner film layer are composited to one body through double-layer extrusion film blowing. The double color polyethylene farmland film is characterized by reflection, aphid repelling, humidity reduction, moisture preservation, weeding and virus prevention. The utility model is applied widely in agriculture, which reduces costs of pesticide and fertilizer, shorten mature period of crops, and increases agriculture yield and incomes.
Description
Technical field
The utility model relates to polyethylene farmland film field.
Background technology
Polyethylene farmland film commonly used is to be that raw material is not distinguished the ectonexine function and processed with the polyethylene resin, and its weak point is function singleness, do not possess simultaneously reflective, drive aphid, the function of lowering the temperature, preserve moisture, cut weeds.
The novel practical content
The purpose of this utility model is exactly at the above-mentioned deficiency of existing polyethylene farmland film, and provide a kind of possess reflective, drive aphid, the double-colored agricultural polyethylene film of the function of lowering the temperature, preserve moisture, cut weeds.
A kind of double-colored polyethylene farmland film is made up of silver grey or white theca externa and black theca interna, and silver grey or white theca externa and black theca interna are combined into one through the double-layer coextrusion blown film.Thickness silver grey or white theca externa is 0.025mm, and the thickness of black theca interna is 0.025mm.
The utility model has the advantages that: double-colored polyethylene farmland film has significantly silver grey or white theca externa and black theca interna, when peasant household uses silver grey or white theca externa outer surface towards sky, the black theca interna outer surface the earth that faces down.
Possess reflective, drive aphid, lower the temperature, preserve moisture, cut weeds, pre-anti-virus functionality.Be used for agricultural, agricultural chemicals, fertilizer cost are descended, the crops maturing stage shortens, and agricultural product increase income, peasant's synergy.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Specific implementation method
With linear low density of polyethylene 50kg, female 2 kg of low density polyethylene (LDPE) 48 kg and silver gray or female 2 kg of white, mixing is the raw material of silver grey or white theca externa 1, with linear low density of polyethylene 50 kg, low density polyethylene (LDPE) 49kg and black masterbatch 1 kg, mixing is the raw material of black theca interna 2, the raw material of silver grey or white theca externa 1 and the raw material of black theca interna 2 are combined into one through double-layer coextrusion blown film equipment blown film, promptly make double-colored one, the smooth double-colored polyethylene farmland of the basis film of any surface finish.The thickness of this double-colored silver grey or white theca externa of polyethylene farmland film (1) is 0.025mm, and the thickness of black theca interna 2 is 0.025mm.
