Abstract
The present invention discloses a kind of agricultural polyolefin synthetic paper of high reflection and combinations thereof, the composition of the agricultural polyolefin synthetic paper of high reflection includes polyolefin resin, natural stone-powder and the inorganic powder for improving reflectivity, and wherein inorganic powder includes zinc sulphide (ZnS), zinc oxide (ZnO), magnesia (MgO), titanium dioxide (TiO2), barium sulfate (BaSO4) and calcium sulfate (CaSO4) among a combination of one or more.By said combination, reflectivity, tearing strength and the pollution resistance of agricultural mulching can be improved.
Description
Technical field
The present invention relates to a kind of agricultural polyolefin synthetic paper and its materials, more particularly to a kind of agricultural polyolefin of high reflection
Synthetic paper and combinations thereof.
Background technique
General agricultural mulching is mainly used to: 1) controlling the humidity and temperature of mulched ground, adjust Soil Micro-environment；2) subtract
Few soil water evaporation and erosion, prevent oxygen to be lost, preservation of fertility；3) inhibit weed growth, reduce germ and insect pest
It grows, reduces the use of pesticide, insecticide.In addition to common black polyethylene film, in recent years in facilities horticulture and closed
It is common to increase emergency light reflex using bichromal member white/black or silver-colored/black in vegetables and fruits factory, improve the sugared content and yield of crop.
It is so black because there is one side on film, so can relative reduction light reflectivity.
As in the effective ways for improving reflection, one is the thickness for increasing film or multilayered structure is formed, is had to increase
The content of ingredient is imitated, it is homogenous plasticized and effective component evenly dispersed more difficult to there is a problem of in its right production process, reaches instead
Less than ideal high reflection effect；Another kind is to form foaming micropore in the film, or carry out special surface processing to film, so
Step is more many and diverse in its production process.
In view of this, the present inventor satisfies the research and development experience for being engaged in related fields according to its many years, carried out for aforementioned disadvantage
It deeply probes into, and actively seeks solution according to aforementioned need, make great efforts research and repeatedly test after prolonged, complete finally

Referring to Fig. 1, the architecture diagram of the manufacture system for a kind of agricultural polyolefin synthetic paper of high reflection.This composition can lead to
It crosses this system and forms the agricultural polyolefin synthetic paper of high reflection, process is as follows: firstly, formula material passes through 1 mixed at high speed of mixing machine.
Then, it is formed by mixture and passes through (or kneader) gelatinization of kncading machine 2 and evenly dispersed.Hereafter, it is formed by gelatinization material
Extruder 4 is persistently fed by pan feeding machine 3, by extruder 4 again abundant gelatinization and squeeze into strips.Hereafter, turbine 5 is rolled to exist
Gelatinization material spreading is kneaded at a high temperature of 150~250 DEG C, to promote gelatinization degree more evenly.Hereafter, calender 6 is by gelatinization material
Spreading is heated again, is made up to best gelatinization and dispersibility, and roll the thickness to form setting, is formed preliminary finished product.
Hereafter, finished product suitably adjusts draw ratio (speed ratio of the roller relative to calender) by feeding machine 7.This
Afterwards, finished product can optionally form required textured surface by embossing device 8.Hereafter, finished product passes through longitudinal stretching equipment 9 and cross
To stretcher 10, to reach the size of setting, and required physical property is obtained.Hereafter, finished product by stretch tempering equipment 11 into
Row tempering, and second of longitudinal stretching and the processing of extension twice are optionally carried out, to ensure the integrality of finished product.Finally, finished product
It carries out shaping and cools down by cooling wheel 12, and wound by coiling machine 13 and be sent to back segment processing or packaging again in rolls.
Referring to Fig. 2, can be covered in when using by the agricultural polyolefin synthetic paper Z of high reflection that above system is formed
On soil ground, so that plant is planted in the hole for manually drilling through the agricultural polyolefin synthetic paper Z of high reflection in soil.Side according to this
Formula can not only reduce ground temperature, and effectively inhibit the weed growth of mulching soil, moreover it is possible to utilize the agricultural polyolefin synthetic paper of high reflection
It is Z-shaped at reflected light increase the illumination intensity of plant base portion, to make up the deficiency of base portion direct light, and drive away and conceal plant back
The pest of smooth surface.
Referring to Fig. 3, it shows each of the agricultural polyolefin synthetic paper of high reflection according to the present invention and commercially available agricultural mulching
Section reflectivity results.As shown in figure 3, the agricultural polyolefin synthetic paper of high reflection according to the present invention not only has in visible light part
