Problems solved by technology

However, acrylate copolymers are flammable polymers composed of three elements: carbon, hydrogen, and oxygen, which are greatly limited in applications that need to meet flame retardant requirements.
[0003] Especially with the increasing demand for flame retardancy in shipbuilding and other fields, acrylic structural adhesive products need better flame retardancy while maintaining the original strength and toughness, which cannot be fully met by existing products.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a two-component halogen-free flame-retardant acrylate structural adhesive and a preparation method thereof. Background technique [0002] Acrylic structural adhesives are widely used in electronics, aerospace, vehicles, ships and other fields due to their high bonding strength, rapid curing at room temperature, excellent weather resistance and stability, and good comprehensive performance. However, acrylate copolymers are flammable polymers composed of three elements: carbon, hydrogen, and oxygen, and their applications in fields that need to meet flame retardant requirements are greatly limited. [0003] Especially with the ever-increasing demand for flame retardancy in shipbuilding and other fields, acrylic structural adhesive products need better flame retardancy while maintaining the original strength and toughness, which cannot be fully met by existing products.
