Abstract

The invention belongs to the technical field of adhesives and particularly relates to a bonding resin for aluminum and plastic composite plates and a preparation method thereof. The preparation method is characterized in that the bonding resin comprises the following components in percentage by weight: 25 to 35 percent of an ethylene-acrylic acid graft or ethylene-methacrylic acid graft, 35 to 45percent of tackifying resin, 20 to 40 percent of viscosity regulator, 5 to 10 percent of vinyltrimethoxysilane or vinyltriethoxysilane and 0.1 to 0.5 percent of antioxidant. In the invention, hot melt adhesive is prepared by a melt blending process, and the components are fully and uniformly mixed by heating and stirring in a reaction kettle. The preparation method comprises: heating a molten substrate resin at 100 to 200 DEG C; adding antioxygen and tackifying resin, melting and uniformly stirring; and finally, adding viscosity regulator and vinyltrimethoxysilane or vinyltriethoxysilane, melting uniformly and discharging. The bonding resin obtained by the technique provided by the invention has high weather resistance and durability and therefore has a wide application prospect.

Description

technical field [0001] 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. Background technique [0002] 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 country has become the ...
