A graphene decorative board used for thermal insulation of building exterior walls and its production process

Abstract

The present invention relates to a graphene decorative board used for heat preservation in the exterior wall of a building and a production process thereof. The graphene decorative board includes an aluminum-magnesium alloy hardness layer (3) as the base layer, and an outer surface of the aluminum-magnesium alloy hardness layer (3). The surface is compounded with a decorative layer (2), the outer surface of the decorative layer (2) is compounded with a nano-violet protective layer (1), the inner surface of the aluminum-magnesium alloy hardness layer (3) is compounded with a polyurethane insulation layer (4), and the polyurethane insulation layer The inner surface of (4) is compounded with aluminum foil anticorrosion layer (5), nano-purple protective layer (1), decorative layer (2), aluminum-magnesium alloy hardness layer (3), polyurethane insulation layer (4), aluminum foil anticorrosion layer (5 ) from top to bottom in sequence, and the decorative layer (2) is a decorative film or coating; compared with the prior art, the present invention not only has good thermal insulation effect, energy saving and environmental protection, strong practicability, but also is durable and has a long service life. Has good flame retardancy and corrosion resistance.

[0004] 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
