Description

Inflatable double-layer transparent thermal insulation plastic sheet and large area thermal insulation plastic sheet

technical field

The utility model relates to a transparent plastic cloth, in particular to an inflatable double-layer transparent heat-retaining plastic cloth and a large-area heat-retaining plastic cloth.

Background technique

Transparent plastic cloth or film is widely used in thermal insulation greenhouses, thermal insulation door curtains and other fields due to its good transparency, light texture, durability, ease of large-scale processing, and low cost. However, the existing various transparent plastic cloth or films , because of its poor ability to isolate cold air, it can no longer meet the needs of the market, especially in the field of thermal insulation, which has been gradually eliminated by the market; later, a double-layer thermal insulation plastic sheet appeared on the market. During use, people found that its The heat preservation effect is not ideal, and there are disadvantages of complex structure, inconvenient use, and high cost;

In order to solve the above problems as soon as possible, people have been trying to find a suitable technical solution.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art, thereby providing an inflatable double-layer transparent thermal insulation plastic cloth with simple structure, easy processing, light texture, good warming effect, and outstanding thermal insulation effect. It also provides a large Area insulation plastic sheeting.

The purpose of the invention of the utility model is achieved by the following technical solutions:

An inflatable double-layer transparent thermal insulation plastic cloth, comprising an upper layer of transparent plastic cloth and a lower layer of transparent plastic cloth, the upper layer of transparent plastic cloth and the lower layer of transparent plastic cloth form a closed cavity, and the closed cavity is provided with There are not less than two joining points for connecting the upper layer of transparent plastic cloth and the lower layer of transparent plastic cloth, and an air filling and deflation nozzle is arranged on the airtight cavity.

Based on the above, a force-bearing edge is provided around the outside of the airtight cavity; the force-bearing edge is formed by combining an upper layer of transparent plastic cloth and a lower layer of transparent plastic cloth.

Based on the above, the binding points are regularly and evenly arranged on the airtight cavity.

Based on the above, the joints are circular joints.

Based on the above, the joints are oval joints.

A large-area heat-retaining plastic cloth, the large-area heat-retaining plastic cloth is composed of a plurality of inflatable double-layer transparent heat-retaining plastic cloths according to claim 1.

Compared with the prior art, the utility model has substantive characteristics and progress. Specifically, the inflatable double-layer transparent thermal insulation plastic cloth has the following advantages:

1. Inflate air between the upper layer and the lower layer of transparent plastic cloth through the inflation and deflation nozzle, which can not only effectively collect sunlight, but also better isolate cold air. This structural design makes the plastic cloth have the outstanding advantages of fast heating and good heat preservation effect ;

2. There are joint points between the upper and lower layers of transparent plastic cloth. When the air is inflated into the airtight cavity, each joint point is connected to the upper and lower layer of transparent plastic cloth. Therefore, the airtight cavity can be made into one piece to avoid its own Rising and moving due to inflation;

3. The plastic sheet is exquisite in structure design, easy to use, low in cost, easy to process, and can be widely used in thermal insulation fields such as thermal insulation greenhouses and thermal insulation door curtains.
