Description
Technical field
The present invention relates to the production fields of plastic film, use band alarm function to mould more particularly to a kind of agricultural planting greenhouse
Expect method for manufacturing thin film.
Background technique
With the development of society, plastic film industry is also evolving growth, agricultural, food packaging, medical and health,
The all trades and professions such as electromechanics have application, especially being more widely applied in agriculturally plastic film, solve China's agriculturally agriculture
The drawback of byproduct insufficient supply.
China is a large agricultural country, and the various vegetable and fruits of agricultural planting need a large amount of plastic film, traditional plastics
Film thickness is mostly 0.08-0.12mm, and thickness is thicker, is unfavorable for photosynthesis of plant as awning film, moreover, such film is anti-
Aging action is poor, is easily torn by various farm animals and stings rotten, night can not issue fluorescence, cannot serve as warning to animal.
And the soft stick of rubber is not set in conventional films, film cannot roll over neat folding, be unfavorable for taking care of, such as application No. is
200920041868.5 file discloses the manufacturing process and anti-skidding plastic film of a kind of anti-skidding plastic film, technique packet
It includes: at least two materials being supplied to die head respectively by each material path, in which: form the melting temperature of the material of plastic film outer layer
Highest, the cooling velocity of the material of formation plastic film outer layer are lower than the cooling velocity of the material of layer adjacent thereto；Described each
Each material is melted in material path, the material of outer layer is made to be in the graininess of incomplete fusion, other layers of material have been in
Full-fusing state；Each material is subjected to coextrusion film blowing at the die head；It is cooling, molding plastic film is obtained, is designed
Complexity, but film cannot warn animal, it is not foldable to be not easy keeping and thickness does not have special consideration, illumination cannot be efficiently used
Improve crop yield.
Existing plastic film type is more, limited using field although they have respective characteristic, there is also
Respective defect.
Summary of the invention
In order to overcome the shortcomings in the prior art, it is an object of the present invention to provide a kind of agricultural planting greenhouses, and band alarm function to be used to mould
Expect method for manufacturing thin film, while the processing technology of the plastic film in the soft stick for being equipped with rubber material among plastic film,
It is rational technology, succinct.
To achieve the purpose of the present invention, technical scheme is as follows:
A kind of agricultural planting greenhouse band alarm function plastic film preparation method, processing step are as follows:
(1) production thin-film material selection；Select the mixing of high density polyvinyl-chloride 20% and low density polyvinyl-chloride 80%
Material of the pvc material as production film, the density of the high density polyvinyl-chloride are 0.942~0.965g/cm3, institute
The density for stating low density polyvinyl-chloride is 0.880~0.915g/cm3.
(2) mixed melting of material；By the pvc material selected in step (1) and boron strontium aluminate and 2, the tertiary fourth of 6- bis-
Base paracresol is thoroughly mixed uniformly by 9: 0.5: 0.5 mass ratio, is heated to molten condition；
(3) first one-step extrusion molding；By the material plastic extruder extrusion molding after melting in step (2)；
(4) calendering formation；With the material of extrusion molding in calender calendaring processes (3), after calendering with a thickness of 0.3-
0.8mm；
(5) further drawing and forming；With heating device by the film heating after rolling described in (4) and stretching, after stretching
With a thickness of 0.03-0.08mm；
(6) soft stick is placed；A soft stick is set every one meter of wide place on a plastic film in step (5) heating process；
(7) cooling and final molding；Plastic film in step (6) is gradually cooled down at room temperature, final molding.Above-mentioned one
The processing technology of kind plastic film, wherein in the step (2), the heating temperature for being heated to molten condition is 200-220
℃。
A kind of processing technology of above-mentioned plastic film, wherein in the step (5), the further drawing and forming heating
Unit temp is set as 160-170 DEG C.
Further, in the step (6), the soft stick is natural rubber material.Flexibility is good, is conducive to wind thin
Flexible volume complications are folded in membrane process, meanwhile, natural rubber is a kind of anti-corrosion material, extends plastic film service life, improves modeling
Expect film service efficiency.
Advantages of the present invention the utility model has the advantages that
The plastic film that the present invention is made by above-mentioned technique has used the close polyvinyl chloride of height and low density polyvinyl-chloride
Mixing application, makes plastic film reach optimum balance between tension stress and tensile strength.Meanwhile it joined boron aluminium in the material
Sour strontium, is the chemical analysis of fluorescent powder, and the capable of emitting fluorescence of night plastic film plays a warning role periphery animal, avoids
Animal tear damage greenhouse film.
For plastic film of the present invention with a thickness of 0.03-0.08mm after calendering and stretching, this thickness thin film is thinner than market plastics
Film is thinner, is conducive to light and transmits into, and crops can preferably carry out photosynthesis, improves crop yield, this film consumption
Material is few and utilization rate is high, meets the market requirement.
