Abstract
The invention discloses a silver and black composite film and white film spaced mulch. The mulch comprises silver layer films, black layer films and white films and is characterized in that the silver layer films and the black layer films are composited to form silver and black composite film segments; the silver and black composite film segments and the white films are spaced; the adjacent edges of the silver and black composite film segments and the white films are combined into a whole via V grooves. The mulch has the beneficial effects that the silver layer films and the black layer films are composited and are spaced by the white films and the spacing distance can be selected according to the growth requirements of different crops, so not only can light be reflected via silver gray or white and heat be absorbed by black but also the ranges of application of the crops can not be reduced and the functions of preserving moisture, preserving heat, improving the soil properties, increasing the nutrient utilization rate, changing the growing period, controlling weeds and avoiding insect pests are further improved comprehensively; by taking low-price linear low density polyethylene as a main material and increasing the proportion of a silver gray masterbatch, the mulch is low in production cost, has good reflective rate and strong aging resistance and is beneficial to application in south China.
Description
Technical field
The present invention relates to the improvement of a kind of mulch film, a kind of silver with multi-protective function is black compound
Film and white films are spaced mulch film.
Background technology
The mulch film used at present, for the polyethylene plastic film for agricultural use of white clear, is mainly used in moisturizing, insulation, improves soil
Character, improves plant recovery of nutrient, changes crop growth period, the most also has weeding to keep away the function of insect pest.But, this mulch film, by
In for single white, can only have white can moisturizing, insulation, improve soil property, improve plant recovery of nutrient, change crop
Trophophase, weeding keeps away the function of insect pest, then can not keep away remove for the weeds and insect pest that can adapt to white.Remove to improve mulch film
Weeds and the characteristic of insect pest, Chinese patent CN203072517U discloses " a kind of double-colored polyethylene farm-oriented mulch ", by upper and lower two-layer
Being composited, upper strata is silver grey or white, and lower floor is black, carries out reflective by silver grey or white, is absorbed heat by black, but by
Then entirety is composited, and again because the reflection of light, so have impact on illumination, this can reduce the scope of application of crop；Wherein: silver
The raw material that grey or white mulch film is used is: linear low density of polyethylene 50Kg, Low Density Polyethylene 48 Kg, silver grey color masterbatch or
Female 2 Kg of white；The raw material that black is used is: linear low density of polyethylene 50Kg, Low Density Polyethylene 49 Kg, black masterbatch 1
Kg.The shortcoming of above-mentioned formula is: due to the large percentage of Low Density Polyethylene, and the price ratio of Low Density Polyethylene is the lowest
The price of density polyethylene is per ton high about 1000 yuan, so improve production cost, the fracture of Low Density Polyethylene simultaneously is drawn
Rate of stretching is the least, and very little, reflecting rate is the poorest for silver gray masterbatch ratio, and very little, ageing resistace is the poorest, no for black master batch 1KG
It is beneficial to the south application of China.
Summary of the invention
It is an object of the invention to provide one and can carry out reflective by silver grey or white, absorbed heat by black, the most not
The crop scope of application can be reduced, improve moisturizing, insulation the most comprehensively, improve soil property, improve plant recovery of nutrient, change and make
Thing trophophase, weeding keeps away insect pest function, and can also improve break-draw rate, reflecting rate, ageing resistace, reduction production cost
The black composite membrane of silver and white films be spaced mulch film.
In order to reach object above, the technical solution adopted in the present invention is: this silver-colored black composite membrane and white films interval row
Row mulch film, is made up of silver color tunic, black tunic and white films, it is characterised in that: described silver color tunic and black tunic are multiple
Synthesizing silver-colored black composite membrane section, and silver color tunic is on upper strata, black tunic is in lower floor；Described silver black composite membrane section is mutual with white films
Being spaced, its adjacent edge is along being combined as a whole；Described white films composite membrane black with adjacent silver section bonding while being " V " shape
Groove, what described silver black composite membrane section was bonding with white films is that " V " shape is stupefied, is molded into one in " V " shape stupefied embedding " V " shape groove
Body；
The raw material weight percentage ratio of described silver color tunic is: linear low density polyethylene 90%, Low Density Polyethylene 5%, silver color
Masterbatch 2%, age resister 3%, through dispensing, melt, be molded；
Described black tunic raw material weight percentage ratio is: linear low density polyethylene 90%, Low Density Polyethylene 5%, black masterbatch
Material 1%, long-lived masterbatch 4%, through dispensing, melt, be molded；
Described white films raw material weight percentage ratio is: linear low density polyethylene 90%, Low Density Polyethylene 5%, age resister
5%, through dispensing, melt, be molded.
The present invention implements also by following measure: described silver color tunic and the thickness of black tunic are 0.004mm, wide
Degree is 600 3000mm, requires to select to use according to the growth of Different Crop；The thickness of described white films is equal to silver color layer
The thickness sum of film and black tunic, width is all consistent with the width of silver color tunic and black tunic.
Described black master batch is black master batch ZY-4081 that Shandong Zhong Yi rubber and plastic company limited produces, and long-lived masterbatch is
ZY-4086 longevity masterbatch.
The beneficial effects of the present invention is: this silver-colored black composite membrane and white films are spaced mulch film, owing to using silver color layer
Film and black tunic are combined, and are spaced by white films, and its interval width can require to select according to the growth according to Different Crop
Use；This mulch film compared with single white mulch film, the advantage not only with beneficially plant growth, and improve light cooperation
With and insecticidal effect；Compared with single silver color mulch film, temperature can reduce 2-3 DEG C；Compared with single black mulch film, easily see
Survey the growing state of crop.So can not only carry out reflective by silver grey or white, absorbed heat by black, and work will not be reduced
The thing scope of application, improves moisturizing, insulation the most comprehensively, improves soil property, improves plant recovery of nutrient, changes plant growth
Phase, weeding keeps away insect pest function.Simultaneously as major part raw material is linear low density polyethylene, and linear low density polyethylene valency
Lattice are relatively inexpensive, so reducing production cost；Owing to improve the ratio of silver gray masterbatch, so improve reflecting rate；Due to
Improve the ratio of black master batch, so improve ageing resistace, southern china can be conducive to apply.
