Abstract

The invention discloses an adhesive resin for an aluminum ceiling. According to the adhesive resin for the aluminum ceiling, high impact polystyrene (HIPS) is introduced into a formula system, so thatseparation between polar and non-polar materials in the adhesive resin is effectively improved; the bonding reaction speed is favorably improved; and the styrene-isoprene-styrene copolymer (SIS) is further introduced and can be matched with HIPS to greatly improve the infiltration effect on aluminum, and the overall compatibility of the system is enhanced, so that the material has good initial adhesion performance in the processing process, and the adhesion speed and the adhesion strength are improved.

Description

technical field [0001] The invention belongs to the technical field of hot-melt adhesives, in particular to an adhesive resin for aluminum ceilings. Background technique [0002] Aluminum ceiling is a general term for decorative interior roof materials. In the past, traditional houses used straw mats, reed mats, and wooden boards as the main materials. With the advancement of science and technology, more modern building materials have been applied. Aluminum ceilings are mainly used in places such as airports, stations, office buildings, shopping malls, subway stations and residences. The shapes and designs are wonderful and changeable, each of which can create different decorative effects. [0003] The surface of the aluminum ceiling is treated with a special process, anti-static, no dust, no dust, can completely meet the requirements of high-precision electronic workshops, hospital operating rooms, biological laboratories and other high-dust and high-clean places. The sur...
