Double-sided waterproof insulation quilt

Abstract

The invention relates to a double-surface waterproof heat preservation quilt which is characterized in that chemical fiber polyester wadding (4) of which the weight per square meter is 300-600g is used as the main body of the heat preservation quilt; the chemical fiber polyester wadding (4) is connected with films (3) on the upper surface and the lower surface by quilting seams to form a substrate; the films (3) are simultaneously melted between the substrate and each of chemical fiber surface fabrics (1) through hot-melt resin; and a layer of bonding film (2) is formed between the polyester wadding (4) and each chemical fiber surface fabric (1) to manufacture the green body of the heat preservation quilt, two ends are sewed by a serger, and bonding hasps with bonding functions are nailed at two sides to form the heat preservation quilt. Because fluffy materials such as textile wastes are mainly selected as the heat preservation main body, the product has light weight, convenient use and low cost; the heat preservation quilt is waterproof on two surfaces, can not be frozen easily and has good heat preservation effect; and the manufacture of a bonding layer, a waterproof layer and a blocking thermal conduction layer is finished by one process, thereby reducing the production cost.

Description

technical field [0001] The invention relates to a double-sided waterproof solar greenhouse insulation quilt. 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 researching various heat preservation quilts, hoping to replace the straw curtains, so that the solar greenhouse can improve the heat preservation 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...

Problems solved by technology

[0003] One is to use some relatively advanced thermal insulation materials, such as thermal insulation plastics, metal films, etc., but because the cost of these materials is too high, the farmers feel that the cost performance is out of proportion, so they refuse

[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 the cost is high, but also the use process is extremely inconvenient

[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
