Description
The invention belongs to a kind of manufacture method of weather resistant plastic film.
As agricultural plastic film, mainly adopted polyvinyl chloride (PVC) RESINS is raw material in the past.Though polyvinyl chloride film is than weather-resistant, tensile strength is higher, and heat-insulating property is better and be easy to bonding.But owing to contain a large amount of softening agent, processing and use in softening agent volatilize in addition that the resin decomposition can cause environmental pollution.Greenhouse canopy internal surface water of condensation is easily extracted the film internal plasticizer out and is vertically dripped, cause crop pest, also because resistance to low temperature is bad, comparatively high temps is easy to again relax, easily absorption dust and density of film are bigger, cost up in the unit surface, shortcoming such as not easy to store is replaced by polyethylene film in recent years gradually.
The day disclosure special permission wear well polythene plastic sheeting for farm use that JP86203147 released, used resin and stablizer are:
Linear low density of polyethylene (d, 0.922g/cm
3) 90 parts
10 parts of ethene---acetate ethylene copolymers (sholexBM05-6)
(VA content 5%)
326 0.8 parts of ultraviolet absorbers Tinuvin
327 0.5 parts of ultraviolet absorbers Tinuvin
In this technology, because used resin is linear low density of polyethylene and ethene---the blend of acetate ethylene copolymer, has higher initial mechanical property so can guarantee film, but stablizer cooperates system unreasonable, do not use oxidation inhibitor again, only use two kinds of benzotriazole compounds as ultraviolet absorbers in the prescription, Tinuvin326 and Tinuvin327 itself is just bad to polyethylene light stabilising effect, and almost there is not a thermal oxidation resistance ability, therefore stronger thermal oxidative reaction must take place in resin in hot-work, produce oxy radicals such as carbonyl and hydroperoxide, can quicken the photooxidation reaction of film under atmospheric condition, shorten the work-ing life of film.In addition, used ultraviolet absorbers is always put higherly in the prescription, accounts for 1.3% of film weight greatly, increased the cost of film, the photo-stability efficiency of UV light stabilizing agent depends primarily on to be selected for use and cooperates, and not proportional with add-on, 1.3% has exceeded normal add-on.
The used resin of wear well polythene plastic sheeting for farm use that Romania patent RomRO8846 2 releases is the new LDPE (film grade) of MI0.3, it is thicker again to make film, so initial mechanical properties value is higher, it is improper that subject matter is that stablizer is selected for use, though also be to select for use a kind of hindered amine and a kind of benzophenone in the prescription as photostabilizer, and add the epoxy Fatty Alcohol(C12-C14 and C12-C18) as the fill-in light stablizer, but selected hindered amine is relatively poor to the polyethylene photo-stability efficiency, and the thermooxidizing of reinforcement effect is arranged in hot-work.Though attempt in the prescription with the epoxy Fatty Alcohol(C12-C14 and C12-C18) as the fill-in light stablizer because and can't form collaboration system between other stablizer, and itself is all not good to heat, light stability, so although film is very thick, weathering resistance only can reach about 2 years.All photostabilizer total amounts are up to 5.4% in this technology, and antioxygen dosage is up to 0.7%, and the total add-on of auxiliary agent is too high, reaches 14.6%, far exceeds normal add-on.Thickness promoter addition greatly in addition is too high, and the film cost is increased significantly, also brings difficulty to processing simultaneously.
The objective of the invention is to select hindered amines as the key light stablizer, with benzophenone, triazines is the fill-in light stablizer, make oxidation inhibitor with phenols, match with phthalocyanine series and azo series pigment and with UV light stabilizing agent and to be combined into the visible light conditioning agent, putting polymkeric substance with low molecule is carrier, be added with above-mentioned photostabilizer, oxidation inhibitor and visible light conditioning agent are made masterbatch.With polyethylene or based on the polyolefin blends of polyethylene, in add lubricant oleic acid acid amides, modifier polyethylene wax and masterbatch prepare the wear well polythene film that reaches 2-3 work-ing life.
The used polyolefin resin of the present invention is new LDPE (film grade) (melt refers to imitate 0.2-3.0), linear low density of polyethylene (melt index 0.5-3.0), the blend of new LDPE (film grade) (melt index 0.2-3.0) and linear low density of polyethylene (melt index 0.5-3.0).(first kind of blend).New LDPE (film grade) (melt index 0.2-3.0) and ethylene-vinyl acetate copolymer (melt index 0.5-3.0, VA content 2-15%) blend (second kind of blend).Linear low density of polyethylene (melt index 0.5-3.0) and ethylene-vinyl acetate copolymer (melt index 0.5-3.0, VA content 2-15%) blend (the third blend).In first kind of blend, linear low density of polyethylene content 5-30%, ethylene-vinyl acetate copolymer content 5-15% in second kind of blend, ethylene-vinyl acetate copolymer content 5-20% in the third blend, sneak into a small amount of linear low density of polyethylene in the new LDPE (film grade), can improve mechanical properties in films, and the adding of ethylene-vinyl acetate copolymer mainly there is contribution to the tough property improvement weather resisteant that improves film, makes that binder resin accounts for 83-94.6% in the film.
The matrix of masterbatch is vector resin, vector resin is generally polymkeric substance or the bigger polymkeric substance of alkane body index that low molecule is put, when vector resin is new LDPE (film grade) (MI7.0), when ethylene-vinyl acetate copolymer (MI2.0) or new LDPE (film grade) (MI7.0) and new LDPE (film grade) (MI50) blend (both than be 2: 1), content is 80-91.4% in masterbatch), make that masterbatch content is 5-15% in the film.
