Abstract
The invention discloses a kind of smooth polynary conversion vinyl house laminated film of function and preparation method thereof, which includes following component according to parts by weight: 50 parts of plastic film；10-20 parts of plastic powders；10-30 parts of long-afterglow material；1-10 parts of optical-thermal conversion material；1-5 parts of photo-catalytic sterilization agent；1-5 parts of auxiliary agent；Wherein, to be that the surface powder is filler modified using surface powder filler modified plastic film preparation refer to the laminated film is uniformly mixed the component in addition to plastic film, then passes through heat pressing process composite molding on a plastic film.Laminated film of the invention is used as greenhouse, improves 2-3 DEG C than common greenhouse in winter, and natural illumination reinforcement, delay can promote the photosynthesis of plant, realize volume increase, the precocity of plant.The bactericidal effect of film can make the disease incidence that powdery mildew, black spot etc. are reduced in moist greenhouse, reduce Pesticide use amount, greenhouse gardening is made to realize green, the multiple effect of energy-saving and environmental protection, volume increase.
Description
Technical field
The invention belongs to agricultural film production technical field, it is related to a kind of photothermal conversion, turns light, Chu Guang and heat preservation sterilization function
The preparation process and formula of the composite material of energy, it particularly relates to a kind of poly modified composite plastic film technology of preparing.
Background technique
For China's agricultural film annual requirement up to 700,000 tons or so, greenhouse gardening covering scope is very extensive, as can sufficiently improving
Awning film realizes the volume increase of crop to the utilization rate of available light under the premise of increasing energy consumption, artificial, chemical fertilizer and pesticide
It increases income, undoubtedly in short supply, problem of environmental pollution will play the role of being obviously promoted for solution China's agro-farming area.
Long-afterglow material is a kind of using rare earth ion as alkaline earth aluminium (silicon) hydrochlorate of activator or yttrium oxysulfide etc., wherein
Y2O2S:Eu3+, Ln is feux rouges afterglowing material, Sr2MgSi2O7:Eu2+,Dy3+For blue light afterglowing material.Long-afterglow material can be one
Determine the energy that extraneous light radiation is received and stored under light irradiation time, and outside in the form of visible light in certain temperature (room temperature)
Boundary emits the embedded photoluminescent material of stored luminous energy.Since Japan in 1975 takes the lead in developing silicate long-afterglow material
Zn2SiO4: Mn, As, the long-afterglow material that hereafter different persistences are longer, twilight sunset effect is more preferable, twilight sunset color is different are successive
Research and development, but until the research that long-afterglow material is applied to bio-sensing and imaging is just had been reported that within 2007, and in agriculture skill
Research in terms of art production application is then rarely reported.
Optical-thermal conversion material is to refer to absorb near infrared light, be generated again by plasma resonance or energy band transition
The new function material of heat.Optical-thermal conversion material is applied to the equipment that solar water heater etc. is converted into thermal energy using luminous energy more
In, it can also be used to medical-therapeutic treatment of human body, under Infrared irradiation high-efficiency low-toxicity kill tumour cell, using energy source can be improved indirectly
Efficiency is a kind of functional material increased income and decreased expenditure.However optical-thermal conversion material is applied to the report of the technical field of agricultural production
Road is then relatively fewer.
Summary of the invention
Present invention aim to address the utilization rates of agricultural film, under the premise of not increasing energy consumption, artificial, chemical fertilizer and pesticide,
Realize the increasing both production and income of crops.
In order to achieve the above objectives, the present invention provides a kind of smooth polynary conversion vinyl house laminated film of function, this is compound
Film includes following component according to parts by weight:
Wherein, which is using the filler modified plastic film preparation of surface powder, the surface powder filler
Modification, which refers to, is uniformly mixed the component in addition to plastic film, then passes through heat pressing process composite molding on a plastic film.
The described plastic film selection polyethylene film, modified polypropene film, ethylene-vinyl acetate copolymer film or they
Blend films.
The described plastic powders selection polyethylene, modified polypropene, in ethylene-vinyl acetate copolymer any one or
Any two or more mixing.
The long-afterglow material be glow or blue light using rare earth ion as alkaline earth aluminium (silicon) hydrochlorate of activator or
Yttrium oxysulfide etc., dosage account for the 5-30% of laminated film quality；Preferably 10-15%.Long-afterglow material both be storage luminescent material,
It is again light conversion material；It will be seen that light is converted to feux rouges or blue light under daylight, night can discharge the luminous energy of storage, play illumination
With the effect of supplementary light.Preferably, feux rouges afterglowing material is Y2O2S:Eu3+, Ln, blue light afterglowing material is Sr2MgSi2O7:Eu2 +,Dy3+。
It is any one or any two or more in described optical-thermal conversion material selection nanoscale CuS, SiC, the ZrC
Combination.
The photo-catalytic sterilization agent selects nanoscale anatase titanium dioxide TiO2, in ZnO, ZrO any one or any two
Kind or more combination.It can not only play the role of sterilization, but also have the function of absorbing ultraviolet light, automatically cleaning, anti-droplet.
The photo-catalytic sterilization agent that the present invention uses has photochemical effect, small organic molecule can be resolved into CO2、H2O rises
To self-cleaning effect；Agriculturally, also adsorbable extra toxic organic gas kills the harmful microorganisms such as fungi, promotes
Crops healthy growth.For awning film, super-hydrophobic effect can prevent surface droplet, and discarded awning film can also urged by light
Change is voluntarily degraded.In addition, wavelength of the nanoscale ZnO therein due to its particle size less than ultraviolet light, therefore can scatter each
The ultraviolet light in direction to weaken ultraviolet radiation, and then protects laminated film matrix, is also used as ultraviolet absorber.
The auxiliary agent includes any one or a few the mixing in age resister, coupling agent, dispersing agent, passes through powder
Dispersion machine adds a small amount of dispersing agent (e.g., toluene) that powder is made to be uniformly dispersed.
The present invention also provides a kind of preparation method of the polynary conversion vinyl house laminated film of above-mentioned light function, the party
Method includes:
Step 1, plastic powders, long-afterglow material, optical-thermal conversion material, photo-catalytic sterilization agent and auxiliary agent are uniformly mixed；
Step 2, the mixture of step 1 is coated in the upper and lower surfaces of plastic film, prepares powder film；
Step 3, it is respectively coated by antiadhesion barrier in the upper and lower surfaces of powder film, metal is set in the outside of antiadhesion barrier
Plate is sequentially placed into hot-press arrangement in a manner of " metal plate/antiadhesion barrier/powder film/antiadhesion barrier/metal plate "；
