Abstract
The invention discloses a transparent anti-fog plastic film composed of the following raw materials, by weight, 80-100 parts of low-density polyethylene, 15-20 parts of an anti-fog agent, 1-5 parts of a fog-reducing agent, 0.1-0.3 parts of glyceryl tristearate, 0.25-0.35 parts of a nucleating agent, 0.01-0.02 parts of glass microspheres, 0.1-0.3 parts of an antioxidant, and 0.2-0.4 parts of fine white carbon black. According to the invention, with the anti-fog agent, plastic film surface tension can be reduced, such that water vapor condensed on the surface of the film can rapidly flow down along the film, and film transparency can be improved. With the transparent anti-fog plastic film provided by the invention, a light transmittance can reach 90-95%, and gloss is high. With the film, long-time fog-resistance can be realized, and flexibility and elasticity are good.
Description
Technical field
The present invention relates to a kind of plastics, be specifically related to a kind of transparent antifogging plastic film.
Background technology
China is large agricultural country, and therefore the demand to agripast canopy film is huge.Ordinary agricultural membrane is in agriculture use, because the booth internal-external temperature difference is big, therefore often condenses the globule at the booth inwall, and forms vaporificly, has had a strong impact on the transmittance of booth, has weakened photosynthesis of plants, influences plant-growth; In addition, globule cohesion also can drop onto the disease and pest generation of bringing out farm crop on the farm crop on the booth.If can change the character of frosting, make frosting change wetting ability into by hydrophobicity, then can make the steam of contact frosting be tiled into moisture film, this layer moisture film is transparent, the scattering phenomenon of mist pearl can not occur.The frosting wetting ability can effectively be eliminated the phenomenon that hazes.
Summary of the invention
The technical problem that solves:At the deficiencies in the prior art, the invention provides a kind of transparent antifogging plastic film, by adding drip agent, antifogging agent and nucleator, improve transmittance and the anti-fog effect of plastics film.
Technical scheme:The invention provides a kind of transparent antifogging plastic film, raw material by following parts by weight is formed: Low Density Polyethylene 80-100 part, drip agent 15-20 part, subtract mist agent 1-5 part, Tristearoylglycerol 0.1-0.3 part, nucleator 0.25-0.35 part, glass microballon 0.01-0.02 part, oxidation inhibitor 0.1-0.3 part, fine particle silica 0.2-0.4 part.
Described drip agent is polyethylene oxide glyceryl monooleate or polyethylene oxide Zerol, can reduce the plastics film surface tension, and the steam that is condensed in film surface is flowed down along film rapidly, increases the transparency of film.
It is described that to subtract the mist agent be modified polyorganosiloxane or organic fluorine and acrylic copolymer, adding subtracts the mist agent makes film surface easily absorb steam, the surplus steam that temperature can not be held in air after descending condenses into water rapidly at film surface, make the vapor pressure after the cooling be lower than saturation vapour pressure, eliminate the condition that fog forms, have the fog effect of subtracting.
Described nucleator is a kind of or its mixture in aromatic phosphoric acid, phosphoric acid ester or the phosphoric acid.
Beneficial effect:Transparent antifogging plastic film provided by the invention, transmittance can reach 90-95%, gloss appearance degree height; Can realize antifog for a long time, and snappiness and good springiness.
