Abstract

The invention discloses a high-gloss coated aluminum sheet using a polyurethane adhesive, which comprises an aluminum sheet substrate, and an adhesive layer, a PVC (polyvinyl chloride) layer, a printing layer and a PET (polyethylene terephthalate) layer which are compounded on the surface of the aluminum sheet substrate, wherein the adhesive used by the adhesive layer comprises 15-25 wt% of polyester polyol with the molecular weight of 20000-30000, 1-5 wt% of dimer acid polyamide with the molecular weight of 100-1000 and 70-80 wt% of organic solvent. The adhesive used by the invention has the advantages of reasonable formula, short curing time and high bonding strength (can reach more than 50 N/2cm), and is convenient to use. The invention has high reflection property and beautiful appearance; and multiple patterns can be developed on the printing layer according to the customer requirements, thereby adapting to various demands of people. The high-gloss coated aluminum sheet disclosed by the invention can be widely used in the industries of suspended ceilings, interior decorations and the like.

Description

technical field [0001] The invention belongs to building decoration materials, in particular to a high-gloss film-coated aluminum plate using a polyurethane adhesive. Background technique [0002] Suspended ceiling refers to the top decoration of the living environment of a house. To put it simply, it refers to the decoration of the ceiling, which is one of the important parts of interior decoration. The suspended ceiling occupies a very important position in the decoration of the whole room. Appropriate decoration on the top surface of the room can not only beautify the indoor environment, but also create a rich and colorful artistic image of the interior space. According to the material of the decorative board, the ceiling can be divided into gypsum board ceiling, metal plate ceiling, glass ceiling, PVC board ceiling, etc. The cost of gypsum board is relatively cheap, followed by PVC board, and metal board is the most durable but the price is higher. The aluminum gusset ...
