Abstract
The present invention discloses a technique for removing protection film for greenhouse. Said invention includes protection film and film-removing agent. Said protection film includes one alkaline medium, at least two adhesives based on acrylic derivative resin and at least one filler or color matter, and the film-removing agent includes second alkaline medium, the described second alkaline medium is sodium hydroxide, sodium carbonate, sodium ethylene diamine tetrucetate salt and sodium nitrilo triacetate or their mixture. Said invention is applicable to greenhouse surface made of glass, hard plastics or elastic plastics. Besides, said invention also provides the application method of its film-removing agent.
Description
Technical field
The invention relates to the diaphragm removed and the remover thereof that are used for the greenhouse.Diaphragm makes transparent or semitransparent surface, greenhouse opaque, and this diaphragm can be removed the agent removal.
Background technology
In horticulture, a lot of plants grow in the greenhouse, to obtain best environment, and temperature for example, illumination, humidity etc.Yet problem is that warm, under the bright day gas condition, plant is born a large amount of light radiation.This can disturb its growth conditions, and influences its growth, even plant is burnt.For avoiding this situation, in the spring, in summer, horticulture generally adopts the method at transparent greenhouse top layer protective mulch, is subjected to the negative effect that radiation brings with protective plant.The essential condition that protective layer need satisfy is that adequately protecting in order to avoid be subjected to the infringement of light and heat to plant can be provided.For this reason, protective layer must contain colorant, for example chalk or titanium dioxide.Another requirement is that the medium that constitutes protective layer must have enough viscosity to the surface, greenhouse.If viscosity is not enough, protective layer can not be resisted the influence of weather, the repetitive administration of having to repeatedly in a season or replacing protective layer.If viscosity is excessive, it will be very difficult removing it in season end.
Summary of the invention
The invention provides a kind of diaphragm removed and remover thereof that is used for the greenhouse; as long as the surface is by glass; the green house that duroplasts or elastoplast are made; the aqueous mixture that can form film can temporarily make transparent or semitransparent surface, greenhouse opaque; protect its implants to avoid the infringement of light and heat, and remove it at an easy rate where necessary.
A kind of diaphragm removed that is used for the greenhouse, diaphragm make transparent or semitransparent surface, greenhouse opaque, and this diaphragm can be removed by described remover.An outstanding advantage of the present invention is that diaphragm can be removed with the method for spraying remover.
Diaphragm comprises: an alkaline media; At least two bindings based on the acrylic acid derivative resin, each mean molecule quantity is 10,000～100,000, acid index greater than 60 less than 300; With filler or colorant.Described remover is to be made by the nitrilotriacetic acid sodium solution 18.5% of the sodium hydroxide 7.5% of the water 72.5% that accounts for total weight percent, xanthans 0.5%, dodecyl benzoic acid 1%, concentration 33%, concentration 40%.
Described filler or colorant are selected from calcium carbonate, silica, silicate, barium sulfite, mica, titanium oxide, the colorant of organic dyeing or zinc oxide.Described diaphragm is: the cellulosic ether thickener accounts for 0.1%～0.5% of gross weight; the hexa metaphosphoric acid dipersant accounts for 0.1%～0.4% of gross weight; foam reducing composition accounts for 0.1%～0.4% of gross weight; bactericide accounts for 0.1%～0.3% of gross weight; viscosity-increasing agent accounts for 0.1% of gross weight; the calcium carbonate of fine grinding or organic toner account for 40%～60% of gross weight; binding accounts for 2%～10% of gross weight; the alkalescence media is that the ammonia of concentration 25% accounts for 0.2%～2% of gross weight, and all the other compositions are water.The particle size of described filler is 1～2 micron.
Described diaphragm is:
Account for gross weight %
Water 17.0～20.0
Foam reducing composition 0.1～0.4
Calgon Sodium hexametaphosphate 0.1～0.4
The ammonia 1.0～4.0 of concentration 25%
The acrylate copolymer 7.0～10.0 of acid index 65
The acrylate copolymer 3.0～6.0 of acid index 145
Calcium carbonate slurry 65.0～70.0
Mixed liquor stirred 10 minutes, had also added following material:
Ethyl hydroxy cellulose 0.4
The amino third ethoxy silane 0.1
Preservative agent 0.1.
A kind of remover that is used to remove the diaphragm removed that is used for the greenhouse comprises: alkaline media; Described alkaline media is a sodium hydroxide, sodium carbonate, ethylene diamine tetra acetic acid sodium salt, sodium nitrilo triacetate, or their mixture.
The said material of the above-mentioned batching of the present invention is product that market is purchased, and does not add special qualification at this.Ethyl hydroxy cellulose is sea, Shangyu, a Zhejiang Province city Shen chemical industry Co., Ltd.The acrylate copolymer of acid index 65 and the acrylate copolymer of acid index 145 are the product that Dutch Aksu company produces.
The present invention is environmental protection; as long as the surface is by glass, the green house that duroplasts or elastoplast are made, the present invention can temporarily make transparent or semitransparent surface, greenhouse opaque; protect its implants to avoid the infringement of light and heat, and remove it at an easy rate where necessary.
The present invention is easy to operate, and is safe in utilization, and manufacture process and use back all do not have any harmful effect to human body and environment.
Specific embodiments
The making of diaphragm is in generator, adds following products in the following order:
Account for gross weight %
Water 18.5
Foam reducing composition 0.25
Calgon Sodium hexametaphosphate 0.25
The ammonia 2.5 of concentration 25%
The acrylate copolymer 8.5 of acid index 65
The acrylate copolymer 4.5 of acid index 145
Calcium carbonate slurry
(calcium carbonate accounts for 70% of slurry weight, water account for slurry 30%) 64.9
Mixed liquor stirred 10 minutes.
Also added following material:
Ethyl hydroxy cellulose 0.4
The amino third ethoxy silane 0.1
Preservative agent 0.1
One kilogram of this batching is before use with the dilution of two premium on currency, and using has good interception after air-dry.According to different shadings and rain fastness demand, can adopt different dilution ratios.
The cellulosic ether thickener can be regulated viscosity, makes its unlikely overflowing in storage.Sodium hexametaphosphate dispersant helps the distribution of calcium carbonate, avoids the cohesion of particle and viscosity to change in time.Bactericide makes coating to preserve in jar.Chloroethene mills amine (chloracetamide) aqueous solution can be used as bactericide.Preservative agent can be selected borax powder, benzoic acid, second how phenol, penta sodium pentachlorophenate etc. for use.
The effect of foam reducing composition is to prevent to produce in the manufacture process bubble.Contain lyophobic dust mixture paraffin wax mineral oil and can be used as foam reducing composition.Calcium carbonate is a kind of filler, can make diaphragm have light-proofness.Be used for the photomask material in greenhouse, the particle size of filler should be 1～2 micron.Also available other materials add or alternative above-mentioned calcium carbonate-filled thing.These materials can be the calcium carbonate that the variable grain size is arranged, silica or silicate, the filler of barium sulfite; Or based on titanium, the white material of zinc oxide, mineral (as mica) or organic toner.
The making of remover is in generator, adds the following products that accounts for total weight percent in the following order: the sodium hydroxide 7.5% of water 72.5%, xanthans 0.5%, dodecyl benzoic acid 1%, concentration 33%, the nitrilotriacetic acid sodium solution 18.5% of concentration 40%.
To stir in the production process always, make the product uniformity.
Remove diaphragm: the remover in the example 2 is sprayed on the diaphragm described in the example 1 with 7 times water dilution, thus make diaphragm behind rainfall or water wash and both can have been removed fully.
