Acrylate adhesive for spot welding process

Abstract

The invention relates to an acrylate adhesive for a spot welding process and belongs to the technical field of a double-component acrylate structural adhesive, and is mainly used for solving the problems that the existing acrylate adhesive is extremely easy to ignite and burn when in spot welding. The acrylate adhesive is characterized by mainly comprising a main agent component and a solidifyingagent component, wherein (1) the main agent component comprises the following raw materials by weight percent: 42%-85% of acrylate monomer containing at least one vinyl group, 0%-12% of methacrylic acid, 0%-30% of elastomer, 0.01%-1% of stabilizing agent, 0%-30% of toughening resin, 0%-20% of fire retardant and 0.5%-8% of peroxide; (2) the solidifying agent component comprises the following raw materials by weight percent: 40%-90% of acrylate monomer containing at least one vinyl group, 0%-23% of elastomer, 0%-20% of methacrylic acid, 1%-10% of accelerating agent, 0%-30% of toughening resin and 0%-20% of fire retardant; and (3) at least one component in the main agent and the solidifying agent contains 10%-30% of elastomer. The acrylate adhesive disclosed by the invention has the characteristic that the adhesive can be used for the spot welding process and can be widely applied to the fields of machinery manufacturing and maintenance.

Description

technical field [0001] The invention belongs to the technical field of two-component acrylate structural adhesives. In particular, it relates to an acrylic adhesive for spot welding process. Background technique [0002] Because the fast-curing acrylate structural adhesive has the remarkable characteristics of rapid curing at room temperature, high strength, good toughness, oily surface bonding, strong adaptability, and simple process, it is widely used in aerospace, aviation, automobiles, machinery, ships, Structural bonding, small-piece assembly, large-piece assembly, emergency repair, anti-seepage plugging, nameplate pasting, etc. It has also been well applied in cutting-edge technology and high technology. [0003] Generally speaking, acrylate adhesives are flammable, especially during spot welding, they are very easy to catch fire and burn, which brings great trouble to the spot welding process. In order to adapt to the spot welding process, it is necessary to develo...
