Problems solved by technology

It is characterized by good heat preservation, good waterproof, and low price; the disadvantage is that kraft paper is used as the surface material, and the service life is low
It is characterized by good heat preservation, excellent water resistance, convenient use and long life; the disadvantage is that the price is relatively high
[0010] To sum up, although there are many types of greenhouse quilts, they all have problems such as: low service life, poor waterproof performance, unsatisfactory thermal insulation effect or high cost, and inconvenient use.

preparation example Construction

[0043] The present invention has no special requirements on the preparation method of the greenhouse insulation quilt, and it only needs to directly compound each layer. In the present invention, the preparation method of the greenhouse insulation quilt preferably includes the following steps:

[0044] Needling and sewing the edges of the first fabric layer and the second fabric layer to form a cavity, and filling the crushed straw into the cavity to obtain a straw composite layer;

[0045] The first reflective aluminum paper layer, the straw composite layer and the second reflective aluminum paper layer are sequentially stacked and compounded to obtain the greenhouse insulation quilt;

[0046] The first reflective aluminum paper layer is in contact with the first fabric layer of the straw composite layer, and the second reflective aluminum paper layer is in contact with the second fabric layer of the straw composite layer.

[0047] In the present invention, the preparation o...

Embodiment 1

[0055] According to the size and parameters in Table 1, the edges of the first fabric layer and the second fabric layer were needle-punched to form a cavity, and the crushed straw was filled into the cavity to obtain a straw composite layer; needle-punched The straw composite layer is sewn into a net shape; the two sides of the straw composite layer are coated with adhesive, and then the first reflective aluminum paper layer, the straw composite layer and the second reflective aluminum paper layer are sequentially stacked and composited to obtain a greenhouse insulation quilt; The first reflective aluminum paper layer is in contact with the first fabric layer of the straw composite layer, and the second reflective aluminum paper layer is in contact with the second fabric layer of the straw composite layer.

Embodiment 2～3

[0057] The preparation steps are the same as in Example 1, except for the thickness of each layer and the particle size of the straw, see Table 1 for details.

Abstract

The invention provides a greenhouse heat preservation quilt and application thereof and belongs to the technical field of heat insulation and preservation. The greenhouse heat preservation quilt comprises a first reflective aluminum paper layer, a first fabric layer, a straw material layer, a second fabric layer and a second reflective aluminum paper layer which are sequentially stacked. The reflective aluminum paper layer can reflect back heat in a greenhouse and plays a good heat insulation effect. A straw material is adopted for replacing cotton felts, synthetic resin foam and synthetic fiber cotton and serves as a heat preservation medium, so that the cost is greatly reduced while the heat preservation effect is guaranteed, and resource recycling and the reduction of environmental pollution are achieved. The result of the embodiment shows that the temperature in the greenhouse obviously rises after the greenhouse heat preservation quilt is adopted, and the heat preservation effectof the greenhouse quilt is not inferior to the heat preservation effect of a greenhouse quilt made of an expensive thick chemical fiber velvet and is obviously superior to the heat preservation effectof a common regenerated cotton greenhouse quilt.

Description

technical field [0001] The invention relates to the technical field of thermal insulation, in particular to a greenhouse thermal insulation quilt and its application. Background technique [0002] With the development of modern agriculture, plastic greenhouses are widely used in the north to grow vegetables. Use the heat of sunlight during the day to increase the temperature in the greenhouse, and cover the surface of the greenhouse with insulation quilt at night to reduce heat loss, keep the temperature inside the greenhouse at a higher temperature, and promote the growth of vegetables and other crops in winter. This ensures that crops can be grown in the north in winter, which increases agricultural output and plays an important role in increasing farmers' income. [0003] The better the thermal insulation quilts used in agricultural greenhouses (abbreviated as greenhouse quilts), the better the temperature in the greenhouse at night can be increased, and the maturity per...
