A new type of greenhouse insulation quilt

Abstract

The invention discloses a novel greenhouse heat preservation quilt, comprising a first layer, a second layer and a sandwich layer located between the first layer and the second layer; the sandwich layer is composed of two types of foam plates having different sizes and arranged in parallel; the foam plates comprise foam plates A and foam plates B; ten foam plates A are provided and are successively arranged at one end of the heat preservation quilt; the foam plates B are arranged successively along the foam plates A; an outer layer of the foam plates is provided with the first layer and the second layer; the first layer is a nonwoven fabric and the second layer is a polyester fabric; the nonwoven fabric contacts three surfaces of the foam plates; the polyester fabric contacts one surface of the foam plates; a splicing space is formed between every two adjacent foam plates; the nonwoven fabric and the polyester fabric are spliced at the splicing space places; the nonwoven fabric separates each of the foam plates. The novel greenhouse heat preservation quilt comprises three layers of the materials, so the structure is simple; the foam plates are selected by the sandwich layer, so the weight is light and the heat preservation effect is good; the weight is light and the materials are wear resistant so that the service life is long.

Description

technical field [0001] The invention relates to the technical field of greenhouse insulation, in particular to a novel greenhouse insulation quilt. Background technique [0002] In recent years, greenhouses covered with thermal insulation quilts are developing rapidly. The biggest advantage of greenhouses is their good thermal insulation performance. Therefore, the insulation measures for greenhouses directly affect the production and operation of greenhouses. Most of the existing greenhouse insulation quilts The use of felt, cotton or straw curtains are all fluffy insulation quilts, which rely on fluffiness to keep warm. It has four major disadvantages: 1. After being rolled, stretched, and squeezed, the fluffy material is easy to lose its fluffiness. That is to say, the heat preservation property is lost, so the insulation effect of fluffy materials is poor, and the service life is short. It can only be used for three to five years, resulting in poor growth of crops in the...

[0002] In recent years, greenhouses covered with thermal insulation quilts are developing rapidly. The biggest advantage of greenhouses is their good thermal insulation performance. Therefore, the insulation measures for greenhouses directly affect the production and operation of greenhouses. Most of the existing greenhouse insulation quilts The use of felt, cotton or straw curtains are all fluffy insulation quilts, which rely on fluffiness to keep warm. It has four major disadvantages: 1. After being rolled, stretched, and squeezed, the fluffy material is easy to lose its fluffiness. That is to say, it loses heat preservation, so the insulation effect of fluffy materials is poor, and the service life is short. It can only be used for three to five years, which leads to poor growth of crops in the shed.

2. The fluffy objects absorb water, and after absorbing water, they cannot play the role of heat preservation, so waterproof work must be done, but the waterproof work is troublesome, labor-intensive and expensive, and the waterproof effect is not good. 3. The fluffy objects are all soft, roll There will be problems such as deformation, deviation, and insufficient bedding when placing. The current method is to increase the height of the shed to increase the steepness of the shed surface, and rely on heat preservation to be slid back to its position by gravity. However, this not only increases the construction cost, but also increases Fourth, the fluffy objects are very light, and they are prone to failure when encountering wind, for example, the insulation cannot be put down or blown away by the wind
