Abstract

The invention discloses a two-component acrylate structural adhesive and a preparation method thereof. The two-component acrylate structural adhesive comprises a component A and a component B, wherein the volume ratio of the component A to the component B is 10: 1. The component A comprises the following components by weight percent: 50%-75% of acrylate monomer, 20%-40% of toughening tackifier, 0.1%-3% of reducing agent, 0.1%-6% of stabilizer and 0.1%-10% of additive. The component B comprises the following components by weight percent: 20%-50% of oxidant, 20%-50% of plasticizer, 10%-20% of toughening agent and 0.1%-10% of additive.

Description

Technical field [0001] The present invention involves a dual component acrylic structural glue and its preparation method. Background technique [0002] The second -generation acrylic structure glue is a dual -component structural glue with a completely reaction.Due to many advantages: fast curing of room temperature and adjustable speed of curing; temperature affects the speed of curing; dual -components do not require strict measurement, convenient use, and facilitate automation;; It can be widely adhered, which is conducive to the assembly of different profiles; high mechanical strength; wide adjustment range, etc.For more than 30 years since the mid -1970s, the second -generation acrylic structured glue has developed rapidly, and products with excellent performance of low -odor products and long -shelter products have been launched.At the same time, with the large application of second -generation acrylic structure glue in the process of modern industrial production and manuf...
