Description
Technical field
The invention belongs to mulch film field, be specifically related to a kind of face, agricultural land covered with plastic film.
Background technology
Face, China agricultural land covered with plastic film was introduced from Japan in late 1970s.Along with China's agricultural technology
Development, face, agricultural land covered with plastic film be called for short " mulch film " use obtained unprecedented development.China becomes at present
For the whole world agricultural " mulch film " the first consumption big country.But " the white pollution brought therewith due to a large amount of uses of plastic film
Problem " the most day by day highlight.Consume substantial amounts of manpower and materials for this country to renovate, advocate waste reclaimation.With
Time, China is also whole world pattern plastic warmhouse booth planting vegetable, the country of fruit area maximum.In recent years, along with modern efficient
The fast development of agricultural facility, in warmhouse booth, full covering with ground sheeting has become general facilities requirement.
But the common agricultural ground covered with plastic film that standard thickness is 0.008mm covers the use time in temperature canopy
It it is 50 days-120 days.The requirement of plant growth in temperature canopy can not be met far away.Along with China's economy grows continuously and fast, agricultural is ploughed
Mode of making also constantly is changing, and " reducing artificial work, capable of circulation nuisanceless " has become modern installations agricultural sustainable development
The inexorable trend of exhibition.
Summary of the invention
It is an object of the present invention to provide a kind of environment-friendly type Reusability agricultural mulch films, to solve existing agricultural film service life
Short, be not easily recycled after aging breakage, and use time one batch one change, the problem of labor intensive material resources.
A kind of environment-friendly type Reusability agricultural mulch films, is made up of black basecoat, intermediate layer and theca externa, sets in thin film
Porose；Overall film thickness is 0.10-0.30mm.
As a further improvement on the present invention, film web a width of 600-1600 mm.
As a further improvement on the present invention, thin film uses co-extrusion film blowing machine group extrusion blow, under co-extrusion film blowing machine
Being provided with online perforating device on the carry-over pinch rolls of side, the longitudinal pitch in hole is 300-600mm；Horizontal spacing is 400-600mm, hole
Footpath is 40-65mm.
As a further improvement on the present invention, theca externa is made up of the raw material of following weight content, linear low density polyethylene
Alkene 41-67%, ldpe resin 15-50%, special ageing-resistant master batch 6-10%；Shabri master batch accounts for 3-8%.
As a further improvement on the present invention, black basecoat is made up of the raw material of following weight content, and linea low density gathers
Ethylene 40-65%, ldpe resin 15-50%, special ageing-resistant master batch 6-10%；Black agglomerate accounts for 4-10%.
As a further improvement on the present invention, intermediate layer is made up of the raw material of following weight content, linear low density polyethylene
Alkene 50-60%, Low Density Polyethylene 34-46%, special ageing-resistant master batch accounts for 4-6%.
The present invention is to utilize co-extrusion film blowing machine to assemble special dies head processed to produce inner face for black, can effective profit
With weeds in physical method removing canopy；Outside is white (or silver gray), can reflect sunlight and strengthen crops illumination.And according to agriculture
Crop-planting spacing in the rows, line-spacing require online punching.The Seedling field planting that can directly be cultivated by crop after overlay film in canopy is reserved to face
In hole.
Because being furnished with ageing-resistant master batch when additionally this film produces, sustainable use 5-7.Therefore peasant household's weeding, repeatedly is saved
The hard work that overlay film, rupture of membranes are transplanted, reduces resource consumption simultaneously, thoroughly solves ultrathin membrane and uses the environment caused dirty in a large number
Dye.
Detailed description of the invention
The present invention is further detailed explanation below.
In embodiment, each raw material is and is purchased: linear low density polyethylene (LLDPE) DFDA9085 is purchased from Tianjin amalgamation
Work, Low Density Polyethylene (LDPE) 2426F is purchased from Lanzhou Petrochemical, and black agglomerate is purchased from U.S.'s Cabot, and white master batch is purchased from moral
