Description
Technical field
The present invention relates to a kind of composition, more particularly, the present invention relates to a kind of composition and preparation and using method that is used to form insulating film (insulating film).
Background technology
Article can be made troubles and problem owing to being exposed to the physical damnification that surrounding environment causes.This damage also can cause enormous economic loss.For example, the high value cash crop (for example: grape, citrus crop (as orange, lemon, bitter orange and natsudaidai), apple, peach, strawberry, almond and tobacco) grower recognizes that observantly frost will produce the crushing infringement of potential to their crop.The restriction that the cash crop grower can be adopted is divided into passive method and active method by the measure of the damage that frost causes.
Passive method generally includes the plantation point (plantingsite) of selecting not have frost risk or frost risk minimum.For example, enclosed mountain valley (closed valley) can catch freezing air and produce dense frost band, and thin frost layer is tended to produce in open Plain.In the area that radiation frost (radiationfrosts) often occur, the plantation point should be designed to be able to freezing air is extracted out from crop.Airflow barrier comprises wind break (windbreaks), artificial forest (plantation), river trees, dykes and dams and buildings along the line.May become the area of problem at radiation frost, mist is a good telltale normally.
The knowledge of soil type aspect also can instruct the selection of plantation point.Usually, dark soil is more than the heat that light soil absorbs, and calculous soil (gravelly soil) is more than the heat that clayey soil (clay soil) absorbs.Compare with the soil that the soil or the kind of the new reclamation of wasteland are implanted with cover crops (cover crop), consolidation, uncovered, wetland can store the thermal radiation of the sun by day and better these heats be radiated at night again.Though cover crops have brought many benefits for plantation, they may bring the risk of frost to plantation during spring, because thick cover crops may make 5-6 ℃ of the highest reduction of nocturnal temperature, thereby further improve the risk of frost damage.
Passive method can also comprise the crop varieties that plantation is cold-resistant.For example, the grape variety (as CHARDONNAY (chardonnay) and Pinot Noir (pinot noir)) that early germinates is than the easier influence that is subjected to frost of kind (as Cabernet Sauvignon (cabernet sauvignon)) of late germination.Some grape varieties can also recover better in spring than other kind (for example, adding (gamay) advanced in years) behind the frost.
Because it is just high more that food crop (food crop) are approached the risk that ground is subjected to frost damage more, so passive method can also comprise field management technology (floor management technique).So, can use frame device (trellising system) to raise crop with ground further away from each other.
Pruning method also can be used for reducing the risk of frost damage.For example, the kind (that is, the most responsive to frost damage) of germinateing is the earliest pruned usually at last.Yet,, postpone the effect that trimming measure is difficult to produce for large-scale commercial applicationsization or in the area of labor force or machinery shortage.
By contrast, when cash crop were subjected to that frost threatens or envrionment temperature changes, active method was devoted to adopt the method that needs external energy to compensate or is prevented photothermal loss.These methods comprise:
(i) overhead sprinkling irrigation (overhead sprinkler irrigation)-this method provides frost protection by discharging latent heat.But sprinkling irrigation (overhead irrigation) also has problems, and be not only because increased the consumption (particularly period of drought) of water, and it also can cause damage caused by waterlogging and drainage of soil bad.The most important thing is,, must consider the capacity and the annual rainfall of dam if overhead sprinkling irrigation is used for frost protection;
(ii) air mixed (air mixing)-frost generally includes inversion layer, and this inversion layer contains the warmer and exsiccant air more usually than the air that more approaches soil surface.If do not have wind or a wind-force deficiency, then man-made machine (for example: blower fan or vertiplane) can be used for mixing air.But, need consider noise pollution (particularly in the many areas of buildings) and energy consumption;
(iii) fuel combustion-combustion fuel can be used as a kind of effectively means of pre-frost protection, it is said that this method is owing to the heat that produces and accumulate in smog insulation layer in the inversion layer of radiation frost.But, can make warm air produce the intensive air-flow if fire is excessive, this air-flow can be broken through the inversion layer of radiation frost, and rises to the height that can not bring benefit.The discharging of carbon also is the problem that such method need be paid close attention to; And
(iv) physics covering (physical covering)-reported that also physics covering (as greenhouse and net (netting)) also can provide certain protection for the antagonism frost damage.But such active protection is only applicable to small-scale plantation.
Therefore, though passive protection method and active guard method can be alleviated the crop damage that causes owing to frost, as indicated above, these methods self have limitation and existing problems.
Frost brings quite a lot of problem can also for the article except that kind of plant or fruit (plant food).For example, when Motor vehicles are exposed to freezing following time of envrionment temperature (for example, below 0 ℃ or 0 ℃), vehicle can be capped last layer ice usually, and this layer ice can make driver's blurred vision, especially when icing when covering on the windows of vehicles.Therefore the vehicle of driving this state is abnormally dangerous.It is very difficult removing ice sheet.At present the method that adopts for this purpose comprises and roots out ice sheet, but this method can cause irremediable damage to the surface below the ice sheet, particularly when this surface be when making by glass.Another kind is used for comprising melting by hot water being poured on the affected surface and with ice sheet from the method that the vehicle supernatant removes ice sheet to be removed.But this also may cause certain risk to vehicle, may cause glass breakage because go up use hot water on the surface (for example, glass) that freezes.
Another is exposed to surrounding environment and can causes the example of great financial loss relevant with fire.According to present extinguishing method, common water is sprayed onto on the article that catch fire of burning when extinguishing, on the pyrophorus residual water can flow to ground and/or since heat on every side evaporate.Lose the water general so make described pyrophorus be exposed to heat on every side by for example evaporating, and make that pyrophorus tends to catch fire once more.Owing to this reason, water is a kind of fire retardant of difference normally.
Have been found that by composition provided by the invention and can overcome or solve above-mentioned prior art problems to small part, described composition can form insulating film executing on the article that are covered with said composition, thereby will the infringement that produce minimizes owing to being exposed to environment (for example: the change of envrionment temperature comprises frost and overheated, dust, moisture).
For succinct purpose, following description only limits to the related application of said composition in agricultural planting and fire-fighting domain discussed.But, it should be understood that composition of the present invention also has practicality widely in that article and environment are isolated in the other field that can be benefited.
The discussion that document, behavior, material, device, article etc. are carried out that this specification sheets comprises is the purpose that is described for to content of the present invention fully.This does not represent or represents in these contents any one or all formed the basis of the prior art in the field related to the present invention before the application's the priority date of every claim or the part of known technology.
