Abstract
A high efficient light modulating additive consists of light modulator, antioxidant, surface activator, disperser and rheological agent with weight range ratio: 29-33:3-5:5-7:55-61:0.3-0.6. The production is carried out by melting light modulator and antioxidant, cooling, agitating with surface activator, disperser and rheological agent and granulating. It advantages include higher quality and output, good additive compatibility, energy resource saving and strong anti-disease ability.
Description
Technical field
The present invention relates to a kind of high performance light adjusting additive that is used to produce plastics light modulation plastic sheeting for farm use or light modulation coating.
Background technology
Existing agricultural plastic film kind is more and more, function is also complete day by day, but making full use of solar energy, particularly effectively utilizing a green gold-tinted, and overcome in the exploitation of medium ultraviolet light to the protection function of crop and awning film negative impact and still be apparent not enough, especially low temperature and less sunshine phase and two is weak according to the phase sooner or later, photorespiration is better than photosynthesis, plant growth is slow, and fine day noon, intensity of illumination caused " dormancy " above light saturation point.General thin and winter protection moisture film can not address these problems.Existing rare earth class or organic class " light-converting agent " dimming function and with other additive compatibility on also have open defect.Coatings industry more lacks the coating that dimming function is arranged.
Summary of the invention
The purpose of this invention is to provide a kind of high performance light adjusting additive, it can remedy the above-mentioned deficiency of prior art.
A kind of high performance light adjusting additive is characterized in that being made up of light-modulating agent, oxidation inhibitor, tensio-active agent, dispersion agent, rheological agent, and their weight range is than being 29-33: 3-5: 5-7: 55-61: 0.3-0.6.
The preparation method of above-mentioned additive is characterized in that earlier granulation is stirred in light-modulating agent and oxidation inhibitor fusion again with tensio-active agent, dispersion agent and rheological agent after the cooling.
Additive compatibility of the present invention is good, can provide a kind of plastics film that makes full use of sunlight for agricultural, make the interior crop of booth under same soil, kind, water, fertile and equal condition of managing, make the raising of planting effect amplitude more than 30% owing to solar energy is fully utilized.Same reason is mixed this additive in the coating, also can reach the purpose of save energy, environment purification.Light modulation ecological film with Additive Production of the present invention, because the interaction of each component in the additive, make the UV-light that sees through film, especially the UV-light of 300nm-350nm, near and the green glow the 550nm, be adjusted to the blue light of 430nm-460nm and the ruddiness of 612nm-670nm, increased the required effective photon of photosynthesis greatly, objectively improved the film transmittance, thereby improved photosynthetic speed, and making crop premature labor volume increase in the booth, quality improves, disease resistance is strong, reaches the purpose of cost-saving synergistic.Same reason is mixed coating with this additive, can make environment become warm pleasantly warm, and oxious component reduces and conserve energy in the environment.
Description of drawings
Accompanying drawing 1 is light modulation film and normal film direct sunlight spectrum comparison diagram.
Accompanying drawing 2 is light modulation film and normal film scattering solar spectrum comparison diagram.
Embodiment
Further specify the present invention below by embodiment.
Embodiment one
Get naphthacene 4.6kg, pentacene 5.65kg, pyrene 20.0kg, sulfo-dipropyl dilaurate 4.35kg, be heated to 216 ℃ of fusions, pulverize.(rheological agent is a known materials with nonanoyl amidcaproic acid amine 6.0kg, LLDPE 59kg, rheological agent again, seeing " plastics science and technology " the 6th phase in 2002 (total 152 phases) for details) 0.4kg puts height altogether and stirs and stir in the machine to 75 ℃, with mixture forcing machine granulation, promptly become light adjusting additive of the present invention.
In manufacturing single thin film and calendered film, add additive of the present invention, its weight is 5 ‰ of film weight, manufacture in the three-layer co-extruded film and add 4 ‰, the film that makes is taken turns test through 3, crop can be gathered in the crops more than the week in advance in the booth, and melon or fruit type crops increases production more than 30%, cauline leaf class crop yield 70%-100%, and disease resistance is strong, the quality height.Additive of the present invention is with low cost, the economic and social benefit height, and the light modulation film that makes is compared with general thin, and sunlight direct projection spectrum and scattered spectrum are all relatively good in the booth, as shown in Figures 1 and 2.
Embodiment two
Get pentacene 9.5kg and add cloudy red native woods ketone 5.5kg, three benzopyrene ketone 16.5kg and thio-2 acid 2 stearyl ester 3.17kg again, be heated to 216 ℃ of fusions, pulverize, again with sorbitan monolaurate 6.3kg, polyethylene one vinyl acetate between to for plastic alcohol ester 58kg, rheological agent 0.5kg high-speed stirring to 75 ℃, adopt the technology granulation described in the embodiment one again and make film, obtain the additive and the light modulation film of effect same.
Embodiment three
Get aza-phenanthrenes 2.22kg, cloudy red native woods ketone 7.05kg, Pi Kaolin 10.5kg, naphthacene 12.23kg, sulfo-dipropyl dilaurate 3.5kg, be heated to 225 ℃, pulverize after the congruent melting, produce master batch with nonanoyl amidcaproic acid amine 5.6kg, diatomite 58.4kg, 0.5kg rheological agent height after stirring again, make coating light adjusting additive of the present invention through pulverizing.This additive is added in the coating with the ratio of 5 ‰ weight, is covered in metope, can make light pleasantly warm in the room in, the winter temperature improve and summer temperature reduce, and can reduce the concentration of objectionable impuritiess such as the interior formaldehyde of environment, benzene effectively.
