Abstract
The invention discloses a kind of black composite membranes of silver and white films to be alternatively arranged mulch, is made of silver color tunic, black tunic and white films, it is characterised in that：The silver color tunic and black tunic are combined into the black composite membrane section of silver, and with the spaced arrangement of white films, adjacent edge is combined as a whole by the way that " V " slot is stupefied.The mulch, due to compound using silver color tunic and black tunic, and by white films interval, interval width can require selection to use according to according to the growth of Different Crop, so can not only be reflective by silver grey or white progress, it is absorbed heat by black, and the crop scope of application will not be reduced, further improve moisturizing, heat preservation comprehensively, improve soil property, plant recovery of nutrient is improved, growth period is changed, weeding keeps away insect pest function；Due to being the ratio advocated peace and improve silver grey color masterbatch with low-cost linear low density polyethylene, so production cost is low, reflecting rate is good, anti-aging property is strong, can be conducive to southern china application.
Description
Technical field
The present invention relates to a kind of improvement of mulch, it is specifically a kind of and meanwhile have multi-protective function silver it is black compound
Film is alternatively arranged mulch with white films.
Background technology
Mulch used at present is the polyethylene plastic film for agricultural use of white clear, is mainly used for moisturizing, heat preservation, improves soil
Character improves plant recovery of nutrient, changes crop growth period, also there is the function that weeding keeps away insect pest certainly.But this mulch, by
In for single white, can only have white can moisturizing, heat preservation, improve soil property, improve plant recovery of nutrient, change crop
Growth period, weeding keep away the function of insect pest, and the weeds and insect pest that can adapt to white cannot then be kept away and removed.It is removed to improve mulch
The characteristic of weeds and insect pest, Chinese patent CN203072517U discloses " a kind of double-colored polyethylene farm-oriented mulch ", by upper and lower two layers
It being combined, upper layer is silver grey or white, and lower layer is black, reflective by silver grey or white progress, is absorbed heat by black, but by
Then whole to be combined, and because of the reflection of light, illumination is affected, this can reduce the scope of application of crop；Wherein：Silver
Raw material is used in ash or white mulch：Linear low density of polyethylene 50Kg, 48 Kg of low density polyethylene (LDPE), silver grey color masterbatch or
2 Kg of white mother；Raw material used in black is：Linear low density of polyethylene 50Kg, 49 Kg of low density polyethylene (LDPE), black masterbatch 1
Kg.The shortcomings that above-mentioned formula, is：Due to the large percentage of low density polyethylene (LDPE), and the price of low density polyethylene (LDPE) is lower than linear
High 1000 yuan per ton or so of the price of density polyethylene, so production cost is improved, while the fracture of low density polyethylene (LDPE) is drawn
It is too small to stretch rate, silver grey color masterbatch ratio is very little, and reflecting rate is too poor, and black master batch 1KG is very little, and anti-aging property is also poor, no
Conducive to the south application of China.
Invention content
The purpose of the present invention is to provide one kind can be reflective by silver grey or white progress, is absorbed heat by black, and not
The crop scope of application can be reduced, moisturizing, heat preservation is further improved comprehensively, improves soil property, improve plant recovery of nutrient, change and make
Object growth period, weeding keep away insect pest function, and can also improve break-draw rate, reflecting rate, anti-aging property, reduce production cost
The black composite membrane of silver be alternatively arranged mulch with white films.
In order to reach object above, the technical solution adopted in the present invention is：The black composite membrane of the silver is arranged with white films interval
Row mulch is made of silver color tunic, black tunic and white films, it is characterised in that：The silver color tunic and black tunic is multiple
The black composite membrane section of synthesis silver, and silver color tunic, on upper layer, black tunic is in lower layer；The black composite membrane section of the silver and white films are mutual
It is alternatively arranged, adjacent edge edge is combined as a whole；The white films and the black composite membrane section of adjacent silver it is bonding be " V " shape on one side
Slot, the black composite membrane section of silver and white films it is bonding be that " V " shape is stupefied on one side, be molded into one in the stupefied embedded " V " shape slot of " V " shape
Body；
The raw material weight percentage of the silver color tunic is：Linear low density polyethylene 90%, low density polyethylene (LDPE) 5%,
Silver color masterbatch 2%, age resister 3% through dispensing, are melted, are molded；
The black layer film raw material weight percent is：It is linear low density polyethylene 90%, low density polyethylene (LDPE) 5%, black
Color masterbatch 1%, long-lived masterbatch 4% through dispensing, are melted, are molded；
The white films raw material weight percentage is：It is linear low density polyethylene 90%, low density polyethylene (LDPE) 5%, anti-ageing
Agent 5% through dispensing, is melted, is molded.
The present invention is also implemented by following measure：The thickness of the silver color tunic and black tunic is 0.004mm, wide
Degree is 600-3000mm, requires selection to use according to the growth of Different Crop；The thickness of the white films is equal to silver color layer
The sum of the thickness of film and black tunic, equivalent width of the width with silver color tunic and black tunic.
The black master batch is the black master batch ZY-4081 of Shandong Zhong Yi rubber and plastics Co., Ltd production, and long-lived masterbatch is
ZY-4086 longevity masterbatch.
The beneficial effects of the present invention are：The black composite membrane of the silver is alternatively arranged mulch with white films, due to using silver color layer
Film and black tunic are compound, and by white films interval, and interval width can require to select according to according to the growth of Different Crop
It uses；The mulch not only has the advantages that be conducive to plant growth, but also improve photosynthetic work compared with single white mulch
With and insecticidal effect；Compared with single silver color mulch, temperature can reduce 2-3 DEG C；Compared with single black mulch film, it is easy to see
Survey the growing state of crop.So can not only be reflective by silver grey or white progress, it is absorbed heat by black, and work will not be reduced
The object scope of application further improves moisturizing, heat preservation, improves soil property, improve plant recovery of nutrient, changes plant growth comprehensively
Phase, weeding keep away insect pest function.Simultaneously as most of raw material is linear low density polyethylene, and linear low density polyethylene valence
Lattice are relatively inexpensive, so reducing production cost；Due to improving the ratio of silver grey color masterbatch, so improving reflecting rate；Due to
The ratio of black master batch is improved, so improving anti-aging property, southern china application can be conducive to.
