Abstract

The present invention is on plastic sheeting, especially a kind of uvioresistant durable long-acting dripping-free polyester PET agricultural film.Comprising the polyester PET thin film that thickness is 0.012~0.50mm, it is characterised in that：Polyurethane or fluororine-carbon coating are coated with polyester PET thin film one side, PVAC polyvinylalcohol plastic sheeting has been covered in the polyester PET thin film another side polyurethane and isocyanates two-component adhesive.The present invention using the big PVAC polyvinylalcohol plastic sheeting of hydrophily as towards the nexine inside greenhouse, it not only translucency, heat-insulation and heat-preservation and acid resistance well outward, also with the excellent anti-performance that hazes.The performance that hazed because this is anti-is that the hydrophily by its material in itself is determined, and rather than what is formed by the antidrip auxiliary agent added in additional coating or material, so the present invention will not produce droplet, it is without dripping function durable long-acting.The present invention makees skeleton using PET film, dexterously overcomes the defect of monolayer polyethylene alcohol PVA film shape stability difference, makes it have the profile of stabilization.

Description

A kind of durable long-acting dripping-free polyester PET thin film
Technical field
The present invention is on plastic sheeting, especially a kind of durable long-acting dripping-free polyester PET thin film.
Background technology
In recent years, the modern installations agricultural of China has obtained vigorous growth, and wherein facilities horticulture is a consumption Energy rich and influential family, and in facilities horticulture, agricultural plastic film is then a kind of important horticultural facility material, is commonly used In covering greenhouse substituting glasshouse.Current agricultural plastic film is mostly polythene PE film or polyvinyl chloride PVC film.For the water droplet damage to crops for preventing vinyl house from being produced by day and night temperature, and in above-mentioned PE The anti-droplet layer of aluminium ester system is coated with film or PVC film, or uses PE, the PVC plastic master batch of addition dripping inhibitor Film, i.e., so-called anti-drop film are made, but the service life of this anti-drop film is short, and no longer than 2 years are not It is that anti-droplet layer is ineffective, is exactly the aging rupture of film.Additionally, PE or PVC agricultural films are also often in modeling Add age resister or anti ultraviolet agent to strengthen its anti-aging and anti-ultraviolet property in material material masterbatch.Due to mesh The service life of preceding agricultural plastic film is short, causes the cost of facilities horticulture and increases, and has been one generally acknowledged It is true.
The content of the invention
It is an object of the invention to provide a kind of durable long-acting dripping-free polyester PET thin film, it is intended to solve it and use In the life-span, keep the technical problem of durable long-acting dripping-free.
The present invention solve above-mentioned technical problem technical scheme be：
A kind of durable long-acting dripping-free polyester PET thin film, comprising the polyester PET that thickness is 0.012~0.50mm Film, it is characterised in that：Polyurethane or fluororine-carbon coating are coated with polyester PET thin film one side, it is poly- in this Ester PET film another side polyurethane and isocyanates two-component adhesive have covered PVAC polyvinylalcohol plastics Film.
Further, it is characterised in that：The PET film is to be added with or without there is hindered amines uvioresistant The plastic sheeting of auxiliary agent.
Further, it is characterised in that：The thickness of the film of the PVAC polyvinylalcohol plastics be 0.012~ 0.05mm。
Further, it is characterised in that：The thickness of the polyurethane or fluororine-carbon coating is 5~20 μ.
The present invention has following beneficial effects
Long service life, the ageing-resistant performance of the uvioresistant of the present invention with polyurethane coating had up to 3 years Fluororine-carbon coating up to 5 years, and use add hindered amines uvioresistant auxiliary agent then up to 8 years or so.For this The cost of facility can be greatly lowered.
The present invention by the use of the big PVAC polyvinylalcohol plastic sheeting of hydrophily as towards the nexine inside greenhouse, it Not only translucency, heat-insulation and heat-preservation and acid resistance are well outer, also with the excellent anti-performance that hazes.Due to this The anti-performance that hazes is that the hydrophily by its material in itself is determined, rather than adding in the additional coating of dependence or material Plus antidrip auxiliary agent formed, so the present invention will not produce droplet, it is without drop function durable long-acting.
The present invention makees skeleton using PET film, dexterously overcomes monolayer polyethylene alcohol PVA film dimensionally stable Property difference defect, make it have stabilization profile.
Specific embodiment
Embodiment 1
The present invention is common bloom polyester PET (PET) film 2 in thickness 0.012mm Simultaneously it is coated with polyurethane or fluororine-carbon coating 1, the thickness of the polyurethane or fluororine-carbon coating 1 is 5 μ；It is general at this The another side polyurethane and isocyanates two-component adhesive of logical bloom polyester PET thin film 2 have covered poly- second Enol PVA plastic sheetings 3, the thickness of the PVAC polyvinylalcohol plastic sheeting 3 is 0.012mm.
Embodiment 2
The present invention is of common bloom polyester PET (PET) film 2 in thickness 0.05mm Face is coated with polyurethane or fluororine-carbon coating 1, and the thickness of the polyurethane or fluororine-carbon coating 1 is 20 μ；It is general at this The another side polyurethane and isocyanates two-component adhesive of logical bloom polyester PET thin film 2 have covered poly- second Enol PVA plastic sheetings 3, the thickness of the PVAC polyvinylalcohol plastic sheeting 3 is 0.05mm.
Embodiment 3
The present invention is of common bloom polyester PET (PET) film 2 in thickness 0.031 Face is coated with polyurethane or fluororine-carbon coating 1, and the thickness of the polyurethane or fluororine-carbon coating 1 is 12.5 μ；At this The another side polyurethane and isocyanates two-component adhesive of common bloom polyester PET thin film 2 have covered poly- Vinyl alcohol PVA plastic sheetings 3, the thickness of the PVAC polyvinylalcohol plastic sheeting 3 is 0.031mm.
The present invention utilizes the excellent hydrophilicity of PVAC polyvinylalcohol plastic sheeting 3, under conditions of with the temperature difference, Its surface will not produce water droplet because of condensation, so that the growth of influence plant.This function without drop is its material What material had in itself, not formed by additive in material or auxiliary agent, therefore this without drop function not at any time Between passage and go down, be durable long-acting.Additionally, the PVAC polyvinylalcohol plastic sheeting 3 is also with good Good printing opacity, heat-insulation and heat-preservation, acid resistance.But the shape stability of the PVAC polyvinylalcohol plastic sheeting 3 Difference, to overcome PVAC polyvinylalcohol plastic sheeting 3 this weak point, the present invention is equally having translucency The common bloom polyester PET thin film 2 of good and dimensional stability performance high is common at this again in addition as skeleton The surface of bloom PET film 2 is coated with a very thin strata urethane or fluorocarbon coating 1 to make ultra-violet radiation resisting Protection.The present invention through the film gasproof that specifies by ASTMG53-88 standards await the honour of your presence anti-aging measurement of test method its Life-span, up to 3~5 years, 2 years or so is aging service life far above general plastic sheeting.
The present invention can also be replaced using the uvioresistant bloom PET film for being added with hindered amines ultraviolet-resistant aid For above-mentioned common bloom PET film 2, so, antiageing effect of the invention is just strengthened, passed through By the test measurement method of ASTMG53-88 standards, be to this surface layer polyurethane or fluorine carbon 1, it is middle be uvioresistant Bloom PET film 2, bottom is the PVAC polyvinylalcohol bonded with polyurethane and isocyanates dual-component binder The measure of the compound of plastic sheeting 3, its ageing resistace is 8 years or so.It is well beyond existing The anti-aging performance of general plastics.
