Abstract

The invention provides a packaging material with high adhesion to magnesium and aluminum alloys and a preparation method thereof. The packaging material is composed of a main agent A and a curing agent B, in parts by weight: the main agent A consists of 35- 80 parts of acrylic monomer, 10-30 parts of toughening agent, 5-15 parts of phosphate functional monomer, 1-10 parts of accelerator, 1-5 parts of stabilizer, 0.1-3 parts of corrosion inhibitor and 0.1-3 parts Silane coupling agent composition; The curing agent B consists of 5-50 parts of initiator, 30-80 parts of toughening agent and 0.5-5 parts of thickener. The encapsulation material provided by the present invention, because phosphate ester functional monomer and corrosion inhibitor are added in main agent A, phosphate ester functional monomer can increase the adhesive force of structural adhesive to magnesium aluminum alloy, and corrosion inhibitor can reduce structural adhesive to magnesium alloy. The corrosion of aluminum alloys improves the encapsulation and corrosion inhibition effects of magnesium and aluminum alloys through the joint action of phosphate ester functional monomers and corrosion inhibitors.
