High-strength bonding resin for aluminum-plastic composite plate

Abstract

The invention provides high-strength bonding resin for an aluminum-plastic composite plate. The high-strength bonding resin is composed of polyolefin, vinyl quinoline, an initiator, tackifying resin and a viscosity modifier. A preparation method of the high-strength bonding resin for the aluminum-plastic composite plate comprises the following steps: heating and agitating by using a reaction kettle; firstly, heating at 120-200 DEG C to fuse polyolefin resin; then adding the initiator and the vinyl quinoline or other grafting compounds; uniformly mixing to obtain a grafting copolymer; further adding the tackifying resin and an antioxidant and fusing and agitating uniformly; and finally, adding the viscosity modifier and fusing uniformly, and discharging to obtain the bonding resin.

Description

[0001] technical field [0002] The invention belongs to the technical field of adhesives, and in particular relates to a special adhesive resin for aluminum-plastic composite panels and a preparation method thereof. [0003] Background technique [0004] Aluminum-plastic panels, also known as aluminum-plastic composite panels, were first developed and produced by ALUDINGEN in Germany in the 1960s, and then improved by FORKEN and ALOCA. , After the 1990s, the production quality gradually stabilized and reached a higher level. After more than 30 years of development, the technology has been relatively perfect. At present, the larger foreign production companies include: Alusingen Company of Germany, Reynolds Group Company of the United States, and Mitsubishi Corporation of Japan. It entered the Chinese mainland in the late 1980s and early 1990s. The aluminum-plastic panel industry has achieved extraordinary development in China in just 10 years. In just a few years, my coun...
