Description
Technical field
The present invention relates to agricultural production, more particularly to a kind of agricultural film antifogging agent and its application.
Background technology
China is an ancient agriculture country, continuous development over time, since the sixties, it is thin to introduce plastics from Japan
Film, start to carry out greenhouse crops cultivation using plastic greenhouse film.The greenhouse film often used is common polyvinyl chloride film, polyethylene
Anti-fogging Film, polyethylene multifunctional composite film etc., but in greenhouse cultivation, often because of water smoke or water droplet that Plastic film surface is formed,
Light transmittance is reduced, influences photosynthesis and the growth of crop, is also easy to make most of crops that pest and disease damage, especially water droplet occur
During drippage, cause rotten of crop, rotten leaf, cause the underproduction.
By application method, no drop, antifogging agent can be divided into " addition type " and " outer spreading type " two class, and " addition type " has master batch system
Make, blown film is difficult and without drop, the fog dispersal phase is short the defects of；Outer spreading type be by with without drop, to be scattered in water etc. molten for fog dispersal function additive
In agent, directly brush or be sprayed on the inside of common greenhouse agricultural film, form layer of transparent film.The product can be used in ageing-resistant canopy film without
Drip, the atomization process that disappears or non-drop greenhouse film anti-fogging property failure or remediation is used during partial failure.
Existing antifogging agent is usually by the compound that forms of a variety of carboxylates compounding, and these compounds are by hydrophilic group and hydrophobic
Base forms, and during fog dispersal, hydrophilic group auto arrangement is in film outside, the one side of close air, and hydrophobic group is then arranged in
On the inside of film, the one side away from air.
Notification number is that CN102719123B Chinese patent document discloses a kind of " outer spreading type anti-drop defogging of agricultural film
Agent composition " in parts by weight, including：Concentration is 5~20wt% silicon-aluminum sol, with SiO2And Al2O3Total amount meter, 10 parts；It is poly-
Ether modified dimethyl polysiloxane, 0.1~15 part；At least one in AEO and APES
Kind, 0.02~12 part；The silicon-aluminum sol represents with mass ratio, SiO2/Al2O3For 1~10.
Above-mentioned prior art can form big micel and be gathered on film, form macromolecular mass during fog dispersal
During, its fog dispersal ability gradually reduces, and until water flows on the ground, its fog dispersal ability can just be recovered, but in actual production, greenhouse
Inner side water droplet is not to produce but persistently produce simultaneously, and elimination fog effect is had a greatly reduced quality.For the less low south of winter temperature,
The underspeed that fog is produced in greenhouse is dripped on ground rapidly with the water droplet for allowing greenhouse inwall to adhere to, but for a long time with small
The form of water droplet hangs over greenhouse inwall, is unfavorable for daylighting, and causes humidity height in canopy, and plant leaf portion may be caused to rot.
The content of the invention
The present invention is on the basis of existing technology, there is provided a kind of agricultural film antifogging agent, is coordinated using the strong raw material of adsorptivity
The big raw material of specific surface area and the raw material with adhesive power, avoid forming macroscopic water droplet on greenhouse, directly will
In the film that water vapor adsorption is formed to antifogging agent, it is more suitable for southern use in winter, and has the function that to adjust humidity in canopy.
A kind of agricultural film antifogging agent, include the component of following parts by weight ratio, activated carbon 30-46 parts, inorganic nano-particle
18-35 parts, calcium sulfate crystal whiskers 5-25 parts, alumina sol 18-30 parts, wherein, the concentration range of alumina sol is 4%-
8%.
It is thin in common polyvinyl chloride as additional type fog dispersal additive present invention also offers a kind of above-mentioned agricultural film antifogging agent
Application in film, polyethylene dripless film, polyethylene multifunctional composite film.
Compared to prior art, the present invention has the advantages that：
1st, activated carbon has such as cellular flourishing, abundant pore structure, and hole inwall has powerful adsorptivity
Can, after a hydrone enters in hole, due to the effect of mutual attractive force between molecule, cause more hydrones to be inhaled
Invest in hole.
2nd, using the big characteristic of inorganic nano-particle specific surface area, strengthen the adhesion of spary coating type antifoggant and canopy film, make
Canopy film anti-fog function effectively extends, and the antifog phase improves more than 50%.Nano-calcium carbonate has anti-ultraviolet ageing and anti-heat ageing
Purpose, strengthens the thermal insulation of agricultural film, and greatly improves agricultural film glossiness, makes agricultural film translucency more preferable.
3rd, calcium sulfate crystal whiskers surface is in highly polar and easily absorbs moisture, can be used as adsorbent.And mixed with inorganic nano-particle
After can be used as adhesive, can preferably be sprayed on agricultural film inner surface.
4th, the use of antifogging agent of the present invention, greenhouse inwall is not in water droplet, the water droplet of bulky grain is less had, from source
Avoid water drippage to cause rotten of crop, the situation of rotten leaf on head, and do not interfere with crop daylighting.
5th, using greenhouse often in order to be incubated, the less opening of door of greenhouse, therefore general humidity is larger in canopy, when in canopy
When humidity is excessive, then it can cause pest and disease damage.Antifogging agent of the prior art, the droplet that can only make to condense in greenhouse make its change
Slided into large water drop, it is impossible to the moisture in absorption air.Therefore, operation is in high- humility state for a long time in canopy, easily hair
Sick insect pest.And this problem is not had then using a kind of heretofore described agricultural film antifogging agent.
6th, high recycling rate, vapor in canopy is absorbed when high humidity, when the big temperature of the sun is high, in antifogging agent
The moisture of absorption can evaporate, and so as to sustainable use, adjust humidity in greenhouse, reduce crop in canopy and occur because moisture is excessive
Rotten leaf and pest and disease damage.
