At present, the plastic greenhouse film of China is mainly polyethylene film, and polyethylene has good cold-resistant, dustproof, the easy characteristic such as processing, but it is a kind of hydrophobic resin, and the surface tension of its film and the surface tension of water differ larger.When early spring or season in late fall, the inside and outside temperature and humidity of plastic greenhouse differs greatly, adopt general thin to cover behind canopy chamber, when plastics film surface temperature reaches dew point when following, airborne steam reaches capacity or will condense into a large amount of droplets at canopy film inwall during supersaturation.The existence of droplet can cause scattering of light or reflection, reduces the light transmission of using awning film as agricultural or gardening, affects the photosynthesis of crop.Simultaneously droplet is dropped in canopy implants, also can cause leaf, stem, bud withered of plant or rot, and directly reduces output and the quality of crop.China carries out the development of polyethylene antifogging film in phase late 1980s, utilize tensio-active agent to improve poly critical surface tension, thereby make the tiny drops of water that condenses upon polyethylene film inwall sprawl into layer of transparent moisture film, and along the downward inflow surface of membranous wall, reach the effect of anti-droplet.
In prior art, the method that improves the wettability of frosting and give its anti-fogging property mainly contains two kinds: apply dripless agent type and interior interpolation dripless agent type outward.The one, outer cladding process adopts high-pressure spray gun in booth, to carry out surface spraying processing.The relevant report of the method is more, as: JP2001211760, JP03-244907, JP2003013038 (A), EP0732387, ZL200510025184.8, ZL200610064906.5 etc.Because this method not only needs spraying equipment, complex operation, cost is higher, and has the problem of solvent evaporates contaminate environment, so additive process in domestic adopt more.The 2nd, interior additive process is exactly in the production process of plastic greenhouse film, and dripless agent is added to and in material resin, together carries out mixing, plasticizing, then Blown Film.As: ZL03119742.6 provide a kind of by maleic anhydride alcohol ether ester mixture and higher alcohols ether mixture, is jointly formed without a polyethylene green house film composition.CN1225929A discloses a kind of antifogging agent with fluorine-containing, silicon-containing surfactant and has been mixed with in proportion demisting high-effective dripless agent with the dripless agent with polyol ester and alkylphenol polyoxyethylene, with it, produces and has good fog dispersal function and without the agriculture greenhouse film that drips efficiency.JP 11310648 employing ethene and hexene copolymer and LDPE and appropriate stearate class antifogging agent, fluorochemical surfactant are blow molded into film jointly, and its anti-droplet validity period reaches 10 months.JP 11322965 provides a kind of antifogging agent being jointly comprised of fluorochemical surfactant and sorbitan monostearate, two Stearic diglycerides, methylene radical distearyl acid amides, hydrolysis stone, adds in LLDPE canopy film and can show good long-term antifogging property.
Above-mentioned patent is substantially all directly to add antifogging agent, although obtaining obvious effect improving aspect the anti-droplet of polyethylene film, aspect the long-lasting of the anti-droplet of film and anti-droplet of initial stage, be not very good.Due to antifogging agent and PE resin compatible poor; hydrophilic small molecules antifogging agent is in the inner problem that has migration and separate out of PE resin; under the continuous effect of water; often there will be antifogging agent to run off gradually and lose its function; its anti-droplet lasting period can only maintain about 3～10 months, and the middle and later periods droplet evil problem of using at polyethylene green house film is like this more outstanding.
Summary of the invention
