Abstract

The invention discloses bonding resin for an aluminum-plastic board and a preparation method thereof. The bonding resin is obtained by extrusion-granulation by a plasticizing blending process using atwin-screw extruder, and has high bonding strength, good bonding durability and film forming performance, less crystal points, and good heat and oxygen aging resistant performance, especially, by introducing HIPS, the bonding speed of the bonding resin is greatly improved, and simultaneously the bonding strength and durability are improved, so as to solve the defects of low bonding strength and poor stability caused by the untimely bonding reaction of the aluminum-plastic board in a high-speed production process, thereby greatly improving the production speed and bonding stability of the aluminum-plastic board.

Description

technical field [0001] The invention belongs to the technical field of hot-melt adhesives, and in particular relates to an adhesive resin for an aluminum-plastic panel, a preparation method thereof and an aluminum-plastic panel. Background technique [0002] Aluminum-plastic panel is a new type of ecological environment building material. Since its invention in the 1970s, it has been widely used due to its advanced composite material structure and characteristics, excellent cost performance and ease of processing, colorful decorative effects and durability, and remarkable resource saving and environmental protection. It is widely used in building curtain wall, indoor and outdoor decoration, advertising plaque, vehicle and boat decoration, furniture manufacturing and other fields. Aluminum-plastic panels are mostly used in urban landmark buildings such as airports, large stadiums, and theaters. Therefore, they have attracted much attention and are important products related ...
