Heat preservation graphene decorative sheet in building outer wall and production flow thereof

Abstract

The invention relates to a heat preservation graphene decorative sheet in a building outer wall and a production flow thereof. The graphene decorative sheet comprises an aluminum-magnesium alloy hardness layer (3) used as a basic layer, a decorative layer (2) is composited onto the outer surface of the aluminum-magnesium alloy hardness layer (3), a nano ultraviolet protective layer (1) is composited onto the outer surface of the decorative layer (2), a polyurethane heat preservation layer (4) is composited onto the inner surface of the aluminum-magnesium alloy hardness layer (3), an aluminum-foil anticorrosion layer (5) is composited onto the inner surface of the polyurethane heat preservation layer (4), the nano ultraviolet protective layer (1), the decorative layer (2), the aluminum-magnesium alloy hardness layer (3), the polyurethane heat preservation layer (4) and the aluminum-foil anticorrosion layer (5) are sequentially composited into a whole body from top to bottom, and the decorative layer (2) is a decorative film or a coating. Compared with the prior art, the heat preservation graphene decorative sheet is not only good in heat preservation effect, energy-saving, environment-friendly and high in practicability, but also durable, long in service life and good in flame retardancy and corrosion resistance.

Description

[technical field] [0001] The invention relates to the technical field of building thermal insulation, in particular to a graphene decorative board used for thermal insulation of building exterior walls and a production process thereof. [Background technique] [0002] With the rapid development of society, people's material enjoyment and quality of life are getting higher and higher. In the current mainstream decoration awareness of "light decoration, heavy decoration", the disadvantages of traditional decoration materials and shapes are highlighted-monotonous visual senses, lack of creativity and centrifugal The "colorful life" in the home is far away; the harmful gas content such as formaldehyde and vinyl chloride monomer is high, the smell is unpleasant, the environmental protection is poor, and the pollution of home decoration has caused serious damage to human health and safety; The process of installing partitions is particularly complicated, rattling, dusty, time-consu...

[0002] With the rapid development of society, people's material enjoyment and quality of life are getting higher and higher. In the current mainstream decoration awareness of "light decoration, heavy decoration", the disadvantages of traditional decoration materials and shapes are highlighted-monotonous visual senses, lack of creativity and centrifugal The "colorful life" in the home is far away; the harmful gas content such as formaldehyde and vinyl chloride monomer is high, the smell is unpleasant, the environmental protection is poor, and the pollution of home decoration has caused serious damage to human health and safety; The process of installing partitions is particularly complicated, rattling, dusty, time-consuming, labor-intensive, and heart-wrenching; therefore, people have long been unbearable, but suffer from the lack of ideal product forms to replace
