Abstract

The utility model discloses a heat insulation cloth, including bonding substrate portion and the metal level together, the metal level still bonds the protective layer that an ultraviolet resistance ability is strong, and its surface is the diffuse reflection face. The bottom of the liner is cloth with fiber wool, the metal layer is pure aluminum foil, and the protective layer is PET resin. The PET resin protective layer of increase can effectual getting rid of the ultraviolet ray, and thermal-insulated effect is better moreover, and the protective layer can also protect the metal level to avoid drenching with the sun in addition, life greatly increased.

Description

a thermal insulation cloth

technical field

The utility model relates to a cloth used for heat preservation and heat insulation, in particular to a heat insulation cloth with strong ultraviolet resistance.

Background technique

Cold and heat protection is an important issue in house construction. For general houses, more than half of the heat energy in winter is lost through windows and roofs. In summer, outdoor direct radiation and diffuse radiation mainly enter the room through windows and roofs. Therefore, It is important to take appropriate measures on windows and roofs to block heat transfer. Existing heat insulation fabrics for windows and roofs are mainly composed of a substrate and a metal layer. The substrate layer insulates heat, and the metal layer reflects heat. In actual use, ultraviolet rays cannot be effectively removed, and the heat insulation effect needs to be improved. The metal layer Directly exposed to the air, the service life is not long enough when the climatic conditions change greatly.

Contents of the invention

In order to overcome the deficiencies of the prior art, the main purpose of this utility model is to provide a heat-insulation cloth with strong ultraviolet resistance, better heat insulation effect and long service life.

The technical scheme adopted by the utility model to solve the technical problem is: a heat-insulating cloth, including a substrate part and a metal layer bonded together, and the metal layer is also bonded with a protective layer with strong anti-ultraviolet ability.

Wherein, the surface of the protective layer is a diffuse reflection surface.

Wherein, the base part is cloth with fiber wool, the metal layer is pure aluminum foil, and the protective layer is PET resin.

The beneficial effects of the utility model are: the heat insulation cloth adds a protective layer with strong anti-ultraviolet ability on the metal layer, which can effectively remove ultraviolet rays, and has better heat insulation effect, and the protective layer can also protect the metal layer from rain Exposure to the sun greatly increases the service life.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a structural representation of the utility model;

Fig. 2 is a sectional view of the utility model;

Detailed ways

Referring to Fig. 1 and Fig. 2, a heat insulation cloth includes a substrate part 1 and a metal layer 2 bonded together, and a protective layer 3 with strong ultraviolet resistance is bonded to the metal layer. The surface of the protective layer 3 is a diffuse reflection surface. Wherein, the base part 1 is cloth with fiber wool, the metal layer 2 is pure aluminum foil, and the protective layer 3 is PET resin. The added PET resin protective layer 3 can effectively remove ultraviolet rays, so that the heat insulation effect of the heat insulation cloth is better. In order to increase the reflection area, the surface of the protective layer 3 is a diffuse reflection surface, and the protective layer 3 can also protect the metal layer 2 from Exposure to rain and sun will greatly increase the service life of the insulation cloth.

The above is only a preferred embodiment of the utility model, but should not constitute a limitation to the utility model, as long as the technical solution equivalent to the utility model is adopted, it should also be within the scope of protection of the utility model.

Claims (3)

1. A heat insulation cloth, comprising a substrate (1) and a metal layer (2) bonded together, characterized in that: the metal layer is also bonded with a protective layer (3) with strong UV resistance. 2. A heat insulation cloth according to claim 1, characterized in that the surface of the protective layer (3) is a diffuse reflection surface. 3.
