Description

It is a kind of to keep the temperature ageing-resistant fog dispersal agricultural canopy film and preparation method thereof
Technical field
The invention belongs to agricultural canopy film fields, more particularly it relates to a kind of ageing-resistant fog dispersal agricultural canopy film of heat preservation And preparation method thereof.
Background technique
Greenhouse is one of critical facility of modern agriculture, it change traditional cultivation method to natural conditions according to Rely.Effectively improve the yield and quality of crop on unit area, relative reduction production cost.Therefore greenhouse plantation Technology is gradually replacing in agricultural and planting industry traditional planting technology and is being accepted by people, and China's canopy film covers according to statistics Area is more than 16000km2, canopy film year usage amount about 1500kt/a, the year amount of upgrading demand about 700kt, and be in cumulative year after year trend. A huge industry is formd.The raw material for producing agricultural canopy film is mainly polyvinyl resin, and common polythene canopy film makes With one layer of white reflection water droplet is agglomerated on middle canopy film inner surface, the transmission of light is affected；And water droplet drips, and increases in canopy Humidity makes crop that disease easily occur；Water droplet is dropped on crop, is also easily caused to rot, is caused the underproduction.Solving polyethylene green house film makes Problem of dripping in, generally use two methods: one is interior additive process, be exactly by with surface-active substance and poly- second Stream drop greenhouse film is made in olefine resin mixing blow molding, and hydrophilic one end moves to the surface of film, so that water droplet is become moisture film and reaches waterproof The effect of drop；Another kind is outer cladding process, and the surface that drip agent is coated to film is exactly made it have hydrophily, reaches anti-stream The effect of drop.
The stream drop fog dispersal lasting period that the stream drop of interior additive process preparation subtracts mist canopy film is short, cannot generally at 3~4 months or so Meet the growth needs of crops.Application type stream drop subtract mist canopy film stream drop fog dispersal the lasting period it is longer, generally at 8 months or more.Its The preparation method of use is directly to coat laminar flow drop on the canopy film surface of polyethylene to subtract mist agent, due to polyethylene and application type stream The polarity spectrum that drop subtracts between mist agent is very big, often there is the poor adhesive force of coating difficulty and coating and polyethylene surface, causes The canopy film stream drop fog dispersal lasting period is short, cannot still meet the requirements.Therefore, the present invention specifically addresses above-mentioned coating liquid and base film layers Between poor adhesion, coating efficiency is low, influence subtract spray drop effect the problem of, while solve due to drip agent and antifogging agent etc. Auxiliary molecules are constantly migrated to film surface and are lost with water droplet, to gradually lose stream drop fog dispersal function, cause the period that works Short problem.

In a preferred embodiment, the drip agent in ageing-resistant stream drop master batch of the present invention is selected from polyol resin Fat acid esters.
In a kind of preferred embodiment, drip agent of the present invention is FWD650, is bought from Town in Shanghai benefit chemical industry Co., Ltd.
Surfactant
Surfactant of the present invention refers to that the interface state that can make its solution system on a small quantity, which is added, occurs significant change Substance.With fixed hydrophilic lipophilic group, can be aligned on the surface of solution.Ionic surfactant can be divided into (including cationic surfactant and anionic surfactant), nonionic surface active agent, are answered at amphoteric surfactant With surfactant, other surfaces activating agent etc..
Surfactant of the present invention is selected from anionic surfactant, cationic surfactant, non-ionic surface One of activating agent, zwitterionic surfactant are a variety of.
As the example of anionic surfactant, including but not limited to: stearic acid, neopelex.
As the example of cationic surfactant, including but not limited to: quaternary ammonium compound.

As the example of nonionic surfactant, including but not limited to: alkyl glucoside (APG), fatty glyceride, Fatty acid sorbitan (sapn), polysorbate (tween).
In a preferred embodiment, surfactant of the present invention is sodium hydroxyethlcellulose and poly alkyl alcohol Ethylene oxide ether is (1~2.5) according to weight ratio: 1 compounding obtains.
Present inventor has found that the activity of the components such as antifogging agent in coating liquid, drip agent needs to be mentioned in the course of the study Moisture content in canopy cannot be condensed into fog well by height, and make it along inflow surface inside film.Anionic and it is non-from Subtype table activating agent can be good at improving the stability of coating liquid, while improve coating liquid in the adhesiveness of base film layer.This Outside, it is found by the applicant that subtracting fog effect using the stream drop that the surfactant of compounding can contribute to extend canopy film, and use sun from Subtype surfactant influences whether the coating effect of coating liquid instead, is easy to make the patch volt property between coat and base film layer It is deteriorated.The possible reason is it is since cationic surface active agent has positive charge, with the amino on the ingredients such as function additive Group etc. aobvious ionic repels each other, and coating liquid stability itself is bad, and due to being deposited in base film layer in coating procedure The ingredients such as a small amount of function additive between the effect of repelling each other, to influence the adhesiveness between base film layer.In addition, by There may be stronger adsorptivity to the pesticide with elements such as chlorine, sulphur in cationic surface active agent, chlorine, sulphur can be promoted The volatilization of equal elements, in the ability that influence pesticide provides nutrition to crops etc., plays a role, while accelerating the further of canopy film Degradation aging.And the above problem that can be cleverly solved using herein described compound surfactant.
