Background technology
Livestock and poultry cultivation does not have special-purpose plastic greenhouse film at present, replaces with polyolefine common vegetable awning film, can only play the effect of keeping out wind and rain and being incubated, and does not have the function of sterilization and disinfection, in case disease pestilence takes place then be difficult to control.Livestock and poultry transmissible disease epidemic prevention now is that the major issue, particularly bird flu that the whole society pays close attention to has progressively threatened human life's safety.Therefore be badly in need of the effectively breed special plastic awning film of purifying aquaculture environment.
Summary of the invention
The present invention is directed to the problem that exists in the breed, develop a kind of special-purpose horticultural covering film for optical efficiency sterilization cultivation, it can effectively kill and remove bacterium in the canopy, and purifies air in the canopy, supports and grows special use.
The principle of foundation of the present invention is, the conduction band electron that the titanium dioxide of utilization≤20nm is caused by quantum effect and the energy level in valence band hole move, specific surface area with super large, realize light-catalyzed reaction with the ultraviolet ray in the daylight at film surface, destroy the energy key of organic gas molecule with the hydroxyl free radical that it produced, make organic gas become single gas molecule, accelerate the decomposition of organic substance, gas, to remove extremely near bacterium in the canopy face air, and it is smelly to eliminate the part animal, makes it be degraded into water or reduction becomes innoxious substance.
Technical scheme of the present invention is: a kind of special-purpose horticultural covering film for optical efficiency sterilization cultivation, comprise polyolefin film and the self-assembly interface molecular film that possesses photocatalysis performance, it is characterized in that, the prescription of forming the interface molecular film comprises one or more in the silicon dioxide gel of zinc oxide colloidal sol, particle diameter≤10nm, colloid solid content≤30% of TiO 2 sol, particle diameter≤20nm, colloid solid content≤30% of distilled water and particle diameter≤20nm, colloid solid content≤30%, also comprises composite dose of coupling and/or has surface-active static inhibitor; Per ten thousand m
2Polyolefin film needs this self-assembly interface molecular film prescription 20-160kg, is coated in the thickness of the self-assembly interface molecular film on the polyolefin film top layer, is 30-300nm.
Produce the production technique of this kind special-purpose horticultural covering film for optical efficiency sterilization cultivation, it is characterized in that, step is as follows:
(1): in polyolefin film blowing process, in the film bubble, spray the self-assembly interface molecular film prescription that possesses photocatalysis performance and produce special-purpose horticultural covering film for optical efficiency sterilization cultivation:
(1), in colloidal sol, add composite dose of coupling, add distilled water and stir, then composite good solution is injected in the stainless steel vessel, pass through filter and enter water pump;
(2), the throttling set with water pump and accurate measurement injects rotation or fixed part flow arrangement with solution;
(3), according to the variant production needs, with high-pressure airless shower nozzle or adjustable gas-liquid shower nozzle liquid is generated vaporific droplet, immerse 90-100 ℃ the film bubble top layer that online production is risen with tractive force with direct projection and drift dual mode;
(4), by film bubble temperature, make the liquid dried that is sprayed onto in the film bubble;
(5), regulate air input and the free air delivery that film steeps with automatic voltage regulator, with an amount of eliminating water vapour;
(2): dip-coating possesses the self-assembly interface molecular film prescription production special-purpose horticultural covering film for optical efficiency sterilization cultivation of photocatalysis performance on the polyolefin film interface of having made:
(1), in colloidal sol, add static inhibitor, add distilled water and stir, then will 1-3 liquid tank of composite good solution injection;
(2), the polyolefin film of rolling is placed on the passive let off roll, by supporting and launch the device of film, film is carried out immersion treatment with its surface in tank;
(3), by the first cover traction and flattening device film is introduced drying unit, with the film oven dry of soaking;
(4), by second cover traction wrap-up or the folding device, film take-up is become finished product.
Polyolefin film of the present invention is meant the film of making of blow moiding method of LDPE, LLDPE, materials such as EVA, mLLDPE.
Beneficial effect of the present invention is: the special-purpose film liquid of light efficiency sterilization breeding integral part all is washing or even edible additive material, and is harmless to human body and livestock and poultry; The light efficiency film utilizes the ultraviolet ray in the daylight to come deodorization and sterilization, saves a part of medicine and labour cost; Can suppress the evil of a part of little insect gives birth to; Can improve the temperature in the canopy.Can also develop otherwise effect coating according to raiser's needs in addition, promote the development of aquaculture.Product of the present invention also can be applied to aquaculture, also can produce good effect.
