Abstract
The invention discloses an agricultural multifunctional greenhouse film which is prepared from the following raw materials in parts by weight: 40 to 45 parts of polyolefin, 45 to 50 parts of linear low-density polyethylene blend and 10 to 20 parts of master batch. A preparation method comprises the following steps: carrying out fusing, mixing, extrusion, drying and granule cutting by utilizing an extrusion or extrusion blow molding process; then carrying out film blowing so as to obtain the agricultural multifunctional greenhouse film. The agricultural multifunctional greenhouse film is simple and convenient in production process and has a good ultraviolet-proof effect, thereby being suitable for large-area popularization and production.
Description
Technical field
The present invention relates to agricultural booth covering material, be specifically related to a kind of multifunctional agricultural greenhouse film.
Background technology
Along with agricultural science and technology is growing, the requirement of greenhouse film is more and more higher, and various function films constantly occur.On market, the covering material of booth mostly is glass, polyvinyl chloride film (PVC), Low Density Polyethylene (LDPE) film and ethylene-vinyl acetate copolymer (EVA) film etc.These greenhouse films have following shortcoming.1, intensity is lower, and in order to guarantee certain intensity, booth, is unfavorable for like this saving and take resin raw material that oil is resource and reducing production costs generally all more than 0.1mm with the thickness of film; 2, the heat retaining property of ldpe film and eva film is poor.Although PVC film heat retaining property is better, during discarded burning, can emit hydrogen chloride gas contaminate environment; 3, the near-ultraviolet ray in sunlight (290～380mm) is not had to iris action.Practical application shows: the near-ultraviolet ray in sunlight not only can make the branch bar of crop aging but also can make the various germ accelerates multiplications growth in soil, makes crop occur the harvest yield of sick fruit, dehiscent fruit, minimizing crop.
Summary of the invention
The object of the present invention is to provide that a kind of intensity is high, good heat preservation performance, to the significant multifunctional agricultural greenhouse film of near-ultraviolet ray barriering effect in sunlight.
Above-mentioned purpose is achieved through the following technical solutions:
A multifunctional agricultural greenhouse film, is made by the raw material of following weight part: polyolefine 40-45 part, linear low density polyethylene blend 45-50 part and masterbatch 10-12 part;
Described masterbatch is made by the raw material of following weight part: the polyolefin resin that the melting index of take is 5-15g/10 minute is carrier, and is added with anti-aging agent, functional aid, and polyolefin resin consumption is that anti-aging agent, the functional aid consumption of 50-95 part is 5-50 part;
Wherein, described anti-aging agent, functional aid are hindered amine, benzotriazole, Viosorb 110, compound in triazine class and contain aluminium, potassium, titanium, silicon, magnesium, iron, calcium, the inorganics of nickel etc.
The preparation method of described multifunctional agricultural greenhouse film: adopt said ratio to get Polyolefin and linear low density polyethylene blend and masterbatch, by extrude or extrusioning blowing process carry out melting, mixing, extrude, after cooling, dry, pelletizing, blown film obtains multifunctional agricultural greenhouse film of the present invention.
The thickness of the obtained multifunctional agricultural greenhouse film of above-mentioned preparation method be 0.05mm film than common LDPE canopy film (thickness 0.1mm) attenuate 1/2 using on market, its heat retaining property improves 0.3 ℃.Multifunctional agricultural greenhouse film of the present invention can be used 1 year continuously, than common LDPE canopy film (thickness 0.1mm), has extended one times of time.And it reaches more than 90% near-ultraviolet ray iris action in sunlight, can improve the light-receiving area of crop simultaneously, regulate photosynthesis promotion plant growth.The tensile strength of film is 260～320kg/cm
2.Than common LDPE canopy film, improve 1 times of left and right.Tearing toughness is 95-100kg/cm
2, higher more than 10% than the functional film on market.
The embodiment of form by the following examples, foregoing of the present invention is described in further detail again, but the scope that should not be construed as the above-mentioned theme of the present invention only limits to following embodiment, all technology realizing based on foregoing of the present invention all belong to scope of the present invention.
