Abstract
Description
Technical Field
[0001] This utility model belongs to the field of thermal insulation cloth technology, specifically relating to a folding thermal insulation blanket for greenhouses. Background Technology
[0002] Agriculture is an industry that utilizes the growth and development patterns of plants and animals to produce products through cultivation techniques. Modern agriculture involves indoor plant cultivation, most commonly in greenhouses. However, greenhouse-grown plants require relatively high temperatures. Indoor plant cultivation typically uses insulating blankets to prevent heat loss during cold seasons; these insulating blankets are a major component of greenhouses.
[0003] Chinese utility model patent No. 201921408816.2 and authorization announcement No. CN 210580266 U provides a 3D greenhouse shading and heat-insulating curtain. The curtain's structure consists of three layers of insulation stacked together. The first insulation layer comprises a woven mesh, a polymer film, and a non-woven fabric layer; the second insulation layer comprises a mixed nano-polyester fiber layer and an animal wool layer; and the third insulation layer comprises a woven mesh, polyester fabric, and non-woven fabric. Clearly, the structure of this heat-insulating curtain, due to the inclusion of a relatively thick polyester fiber layer and animal wool layer, presents problems not only in its preparation, storage, and transportation, but also because the animal wool layer is highly absorbent, causing significant inconvenience during use. Utility Model Content
[0004] The purpose of this invention is to provide a folding thermal insulation blanket for greenhouses that not only has good heat preservation effect, but is also thin and easy to fold up.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A folding thermal insulation blanket for greenhouses is characterized by comprising: a thermal insulation layer formed of a soft plastic board, with a protective layer of woven fiber fabric covering both sides of the thermal insulation layer; and a thermal insulation reinforcement layer formed of an aerogel layer adsorbed on both sides of the thermal insulation layer.
[0007] The additional technical features constituting the above-mentioned folding thermal insulation blanket for greenhouses also include:
[0008] 1. A plastic film protective layer is provided between the insulation layer and the protective layer;
[0009] 2. The soft plastic board constituting the insulation layer is an EVA material plastic or PE foam board made of ethylene and acetic acid copolymer;
[0010] 3. The insulation layer, the insulation reinforcement layer, and the plastic film protective layer are bound together in a straight line;
[0011] 4. The thickness of the soft plastic sheet constituting the insulation layer is between 1.0 and 3.0 mm.
[0012] Compared with the prior art, the folding insulation blanket for greenhouses provided by this utility model has the following advantages: First, because the insulation board is made of foldable soft plastic board, the folding performance of the insulation blanket is better, making it easier to fold and unfold during use, and it is less likely to break, thus extending its service life; Second, because the insulation layer is formed by aerogel layer adsorbed on both sides of the insulation layer, the overall insulation performance of the insulation blanket is greatly improved, making it more suitable for use in cold regions with large day-night temperature differences. Attached Figure Description
[0013] Figure 1 This is a structural schematic diagram of a folding thermal insulation blanket for greenhouses according to the present invention. Detailed Implementation
[0014] The following is a detailed description of the folding thermal insulation blanket structure for greenhouses provided by this utility model, with reference to the accompanying drawings.
[0015] like Figure 1 The diagram shows a structural schematic of a folding thermal insulation blanket for greenhouses provided by this utility model. The structure of the folding thermal insulation blanket includes an insulation layer 1 made of EVA plastic board (or soft plastic board such as PE foam board) with a thickness between 1.0 and 3.0 mm. At the same time, left and right thermal insulation reinforcing layers 41 and 42 formed by aerogel layer are attached to the two sides of the insulation layer. Left and right protective layers 2 and 3 made of fiber woven fabric (or geotextile) are attached to the outer sides of the left and right thermal insulation reinforcing layers 41 and 42. The above structure is then fixed together by left and right fiber threads 11 and 12 (or integrated fiber threads) to form a folding thermal insulation blanket.
[0016] This thermal insulation blanket, due to the use of EVA plastic material (or soft plastic boards such as PE foam board) formed by copolymerizing ethylene and acetic acid to form the insulation layer 1, not only has better folding performance, but also makes the folding and unfolding performance more stable during use, less prone to breakage, and extends its service life. At the same time, because this aerogel layer is a low-density, high-porosity nanoporous material with pore size between 1 and 100 nm and thermal conductivity as low as 0.012 W / (m·K), it is currently recognized as a solid material with extremely low thermal conductivity and is also currently the lightest solid, with excellent thermal insulation performance. On both sides of the insulation layer 1 formed by EVA plastic material (or soft plastic boards such as PE foam board), an adsorption process is used to form a thermal insulation reinforcement layer made of alumina aerogel (zirconia aerogel and carbon aerogel layers can also be selected), which further improves the thermal insulation effect of the blanket and can meet the needs of use in cold regions with large day-night temperature differences in greenhouses.
[0017] In the structure constituting the above-mentioned folding thermal insulation blanket for greenhouses, since the thermal insulation reinforcing layers 41 and 42 formed on both sides of the insulation layer 1 are formed by adsorption, in order to prevent the relatively rough surface of the left and right protective layers 2 and 3, which are made of woven fiber fabric (or geotextile), from rubbing against each other during the repeated folding and unfolding of the insulation blanket, a left plastic protective film layer 51 and a right plastic protective film layer 52 are provided between the insulation layer 1 and the protective layers 2 and 3 for protection. The smooth surface of the left and right plastic protective film layers can effectively protect the left and right thermal insulation reinforcing layers 41 and 42.
