Easy-to-accommodate heat insulation fabric layer structure

Abstract

The invention relates to an easy-to-accommodate heat insulation fabric layer structure. The outer layer of the structure is a sealing cavity structure formed by the cutting and stitching of waterprooffabrics, cat hair yarns are stitched in the sealing cavity structure of the waterproof fabrics, the two ends of the cat hair yarns are stitched on the upper and lower surfaces of the interior of thesealing cavity structure to form multiple separation structures in the sealing cavity structure, air taps are arranged on the waterproofing fabrics, the air taps are fixed to the waterproofing fabricsthrough bonding and sealed by sealing glue, the part between the waterproof fabrics and between the waterproof fabrics and the cat hair yarns are stitched by adopting stitching yarns and sealed by adopting the sealing glue, and the heat insulation fabric layer structure is used by the inflation of the air taps and accommodated by the deflation of the air taps. According to the heat insulation fabric layer structure, the structure can be used by inflation and accommodated by deflation, the heat insulation effect is ensured while space is not occupied, and the structure is easily accommodated.

Description

technical field [0001] The invention relates to a heat insulation structure, in particular to an easily accommodated heat insulation cloth layer structure. Background technique [0002] Heat insulation materials are materials that can block heat flow transfer. They are generally divided into three categories: porous materials, heat reflective materials and vacuum materials. At present, heat insulation materials are widely used in building exterior walls, pipe insulation, and daily household protection and electrical insulation. Generally, heat insulation, heat reflection, heat radiation and other methods are used to isolate most of the heat in the outer environment of the material, and then play the role of heat insulation. At present, the most used heat insulation materials are mainly foam plastics and fibers. As well as reflective heat-insulating coatings, etc., the market mainly focuses on research materials. Researchers tend to study the functionality and environmental p...

Problems solved by technology

[0003] At present, research on the structure of heat insulation materials mainly includes honeycomb structure, multi-layer flake structure, laminated structure and sandwich structure, which are mainly used in military tents and other protective equipment. The thermal effect is good and widely used, but this kind of structure is not suitable for carrying, and the production cost is high; the multi-layer flake and laminated structure has the characteristics of light weight, ultra-thin, high-efficiency heat insulation, and good stability, and is widely used in aerospace and other special applications. Field, due to the high technical requirements of this kind of structure, the materials used are relatively harsh, and it is not suitable for mass production and application. The sandwich structure is generally filled with air, flame-retardant foam and materials with low thermal conductivity, and the structure is stable and heat-insulated. The effect is good, but this structure has high requirements for the adhesive, the rigidity of the material is strong, and it cannot be used in portable applications

[0004] The above structures are widely used, but the amount of expansion and contraction is small. For the part with a large thickness of the heat insulation layer, if it is to be completely filled, a large amount of material will be consumed, which will increase the cost virtually. Moreover, the material of the heat insulation material currently used It is relatively hard, and cannot realize the functions of stretching, arbitrary folding, and storage at any time. Therefore, research on a thermal insulation cloth layer structure that is easy to store and has low thermal conductivity is important for reducing the cost of thermal insulation materials and for practical and simple applications. It is very important to make the thermal insulation effect of the thermal insulation material good. It can be inflated according to the thickness and can be folded and reused to realize the storage and portable application of the thermal insulation material.
