Technical field
This utility model belongs to agricultural facility field, is related to a kind of high-tech heat preservation energy-saving product, more particularly, to a kind of base
In the multi-functional coverlay in the greenhouse of PET material.
Background technology
Under current environment, low-carbon economy developmental pattern all in the application advocating resource energy-saving material, is advocated energetically in the whole world.
In existing greenhouse covering film, application most for PE thin film, next to that glass, PC plate etc.；These materials are more or less all
There are some serious defects, for example：Its heat-insulating property is not good, and after 3 years, light transmittance is only original 50% about, and hinders
Combustion poor-performing；For glass, 1m2The grammes per square metre of (5mm thickness) glass is 12.5kg, and the quality of its unit volume is far above it
His material, and its heat-insulating property, security performance be not good；Although high-grade garden glass has 85% high transmission rate and longer
The advantages of service life, fire resistance are preferable, but, lead to the disadvantage that because of the property of its material itself, e.g., poor safety
Property also can not be ignored；For PC plate, because its light transmittance is poor, it is difficult to meet the required standard of modern greenhouse coverlay.
Due to the particularity of application scenario, modern greenhouse coverlay must have anti-flammability, because Greenhouse System may be with
Shi Fasheng fire.The factors such as operating in greenhouse for the such as welding or cultivation machine when the shortcoming of Circuits System, repairing have
Lead to the danger of fire.Related data shows, when fire occurs, the intensity of a fire can pass through rapid and large-area turn of greenhouse combustible material
Move, easily damage greenhouse and the staff in greenhouse is damaged；In addition, the plant in greenhouse can also be destroyed.Therefore
Greenhouse covering film must have anti-flaming function, and has higher stability for ultraviolet irradiation；Also need simultaneously
The problems such as cost of consideration material and expected service life；Its life-span is at least expected more than 10 years, and, must also be rational
In price, for this reason, it is necessary to new improvement is made to the structure of existing greenhouse covering film.
Utility model content
The purpose of this utility model is for above-mentioned deficiency of the prior art, by changing the knot of greenhouse covering film
Structure, selectively set up flame-retardant layer and uvioresistant coating in each layer of greenhouse covering film, a kind of greenhouse based on PET material is provided
Use multi-functional coverlay.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that：
A kind of based on the multi-functional coverlay in the greenhouse of PET material, including the upper, middle and lower boning successively, institute
State the upper, middle and lower and be PET material；The inner and outer surfaces of described upper strata and lower floor are equipped with uvioresistant coating, or,
The outer surface of described upper strata and lower floor is equipped with uvioresistant coating, or, the outer surface on described upper strata is provided with uvioresistant coating；Institute
State the thickness of upper strata, middle level and lower floor than for 2：1：2.
Further, the inner and outer surfaces of described upper strata and lower floor simultaneously or are selected one and are provided with flame-retardant layer.
The utility model proposes the greenhouse based on PET material with multi-functional coverlay, there is advantages below：
1st, by its bulk strength, thang-kng effect are enhanced with the optimization of each Rotating fields of multi-functional coverlay to described greenhouse
The performances such as fruit.
2nd, pass through selectively to set up flame-retardant layer, uvioresistant coating in described greenhouse with each layer of multi-functional coverlay,
Make product have preferable fire resistance, ageing resistace, and then promote the service life of product at least up to 10 years.
3rd, above-mentioned greenhouse, with the cost of multi-functional coverlay is relatively low, cost performance is higher, can preferably meet modern greenhouse
The required standard of coverlay, has higher popularizing value.
Brief description
Fig. 1 is structural representation of the present utility model.
In figure：1- upper strata, 2- middle level, lower floor -3.
Specific embodiment
Describe preferred embodiment of the present utility model below in conjunction with the accompanying drawings in detail.
Refer to Fig. 1, the utility model discloses a kind of based on the multi-functional coverlay in the greenhouse of PET material, including according to
The upper strata 1 of secondary bonding, middle level 2 and lower floor 3, described upper strata 1, middle level 2 and lower floor 3 are PET (polyethylene terephthalate
Ester) material, the inner and outer surfaces of described upper strata 1 and lower floor 3 are equipped with uvioresistant coating, or, described upper strata 1 and lower floor 3 outer
Surface is equipped with uvioresistant coating, or, the outer surface on described upper strata 1 is provided with uvioresistant coating；Preferably simultaneously on described upper strata 1
And the outer surface of lower floor 3 sets up uvioresistant coating.The thickness of described upper strata 1, middle level 2 and lower floor 3 is than for 2：1：2.Experiment shows,
Now the performance such as the bulk strength of described covering material, thang-kng effect is obviously improved.
Above-mentioned the greenhouse PET material selected by multi-functional coverlay and single-glass, plastics PC plate, plastics PE thin film
