Insulating quilt of sunlight green house

Abstract

The invention relates to an insulating quilt of a sunlight green house. The insulating quilt is characterized in that chemical fiber polyester wadding (2) with the grammage of 250-600g is used as a main body of the insulating quilt, wherein the lower surface of the chemical fiber polyester wadding (2) is formed into a matrix together with lower chemical fiber cloth (1) by a quilting method, and the upper surface of the chemical fiber polyester wadding (2) and the lower surface of upper chemical fiber cloth (4) are mutually bonded together by hot melting resin by a hot melting method; and four edges of the chemical fiber polyester wadding (2) and the chemical fiber cloth are sewed to obtain the insulating quilt. A fluffy body mainly containing textile waste is used as the insulating body, thus the insulating quilt has light weight, convenient use and low cost, and the price of the insulating quilt is within 1.5 times that of a straw curtain. The insulating quilt has good insulating effect, because rain water is not easy to enter the insulating main body, the insulating quilt cannot be frozen in winter, thus the insulating effect is outstanding. The insulating quilt solves the problem of incompatibility of various fibers and plastics, finishes the manufactures of a splicing layer, a waterproof layer and a heat conduction resistant layer at a time and reduces the cost.

Description

technical field [0001] The invention relates to a thermal insulation quilt for a solar greenhouse. Background technique [0002] With the maturation of facility agriculture technology, solar greenhouses have developed rapidly in my country, especially in the northern regions of my country with a latitude of 30°C-45°C, the construction of solar greenhouses has become a way for local farmers to get rid of poverty, save water and reduce environmental damage. main method. In the past 20 years, researchers have been studying various insulation quilts, hoping to replace straw curtains, so that the greenhouse can improve the insulation effect in winter and increase the output of crops. However, it is always difficult to form a real sense of industrialization of the thermal insulation quilts that have been developed, and it is still the main thermal insulation body to this day. This is because all kinds of patented inventions always have some of the following three defects: [000...

AI Technical Summary

Problems solved by technology

[0003] One is to use some relatively advanced thermal insulation materials, such as thermal insulation plastics, metal films, etc., but the cost of these materials is too high for farmers to use

[0004] Second, in order to increase the warmth retention, the design of some thermal insulation quilts is simply considered to use thick materials to increase the thickness of the thermal insulation body, instead of using bulky thermal insulation materials to replace these thick textile wastes as the main thermal insulation body. Not only violates the principle of heat preservation, but also makes the produced heat preservation quilt too heavy, not only costly, but also extremely inconvenient to use

[0005] The third is that the surface of a large number of thermal insulation quilts is not waterproof. Although some fabrics with waterproof surface are used, these fabrics are used under the natural conditions of cold winter and high altitude. The damage of the layer will soon make it waterproof, and it is impossible to use it for 5 years or even 8 years as stated in the promotion manual.

Because the surface is not waterproof, it is easy to freeze in cold winter, and the insulation effect is poor, and the insulation quilt cannot be put away in time after freezing, which affects the sunshine time of the greenhouse
