Problems solved by technology

However, zinc alloy materials also have the disadvantages of poor stability and poor corrosion resistance. At present, most acrylic structural adhesives on the market have a significant decrease in bonding strength when bonding zinc alloy structural parts, which affects the assembly of notebooks. Reliable and stable, so higher requirements are put forward for the structural adhesive used for bonding zinc alloys

Abstract

The invention relates to acrylate structural glue suitable for zinc alloy bonding. The acrylate structural glue comprises a component A and a component B. The component A comprises methacrylic acid, an acrylic monomer, a toughening agent I, a toughening agent II, a reducing agent, a stabilizer and a surface treatment agent. The component B comprises an oxidant, epoxy resin, a plasticizer, a fillerand a pigment. The above components A and B are uniformly mixed according to a volume ratio of the component A to the component B of 10: 1 to form the acrylate structural glue. The acrylate structural glue has excellent adhesiveness to conventional materials such as an ABS plastic alloy, an electrophoretic ED layer and anodized aluminum and is especially suitable for bonding of new materials in the zinc alloy notebook bonding industry.
