Abstract

The invention relates to a high temperature resisting magnesium phosphate adhesive with high strength and a preparation method thereof. The invention provides a phosphate-based metal adhesive. The adhesive comprises the following components in parts by weight: 30-50 parts of magnesium hydroxide, 80-100 parts of phosphoric acid, 5-10 parts of aluminum hydroxide, 40-60 parts of silicon sol, 10-20 parts of alumina sol, 5-10 parts of aluminum borate, 3-5 parts of sodium fluosilicate, 3-5 parts of sodium pyrophosphate, 5-8 parts of triethanolamine, 3-6 parts of natural rubber, 2-4 parts of acrylic ester, 5-10 parts of a polyvinyl acetate emulsion, 3-6 parts of an acrylic emulsion, 20-30 parts of ethanol, 5-10 parts of bentonite, 5-10 parts of silicon carbide, 3-5 parts of quartz sand, 5-10 parts of borax, 2-4 parts of zinc powder, 3-6 parts of methyl methacrylate, 3-5 parts of a surfactant and 30-50 parts of water. The combining strength of the phosphate adhesive to a ceramic wafer can reach over 2.8MPa. After high temperature endurance test, the adhesive can still reach better bonding strength.

Description

[0001] technical field [0002] The invention provides a metal adhesive, in particular relates to a phosphate-based metal adhesive, and belongs to the technical field of adhesives. [0003] Background technique [0004] Adhesive is a chemical product manufactured through ingenious formula and reasonable production process. At present, adhesives mainly composed of synthetic polymer materials account for about 70% of the total. Most of these adhesives are organic adhesives with low operating temperature. [0005] Inorganic adhesives are a wide range of adhesives composed of inorganic salts, inorganic acids, inorganic alkali metals and metal oxides, hydroxides, etc. The outstanding advantage of this type of adhesive is that it has excellent high temperature resistance and can be used in the temperature range of 180-2900°C. In addition, it has high bonding strength, small curing shrinkage, excellent durability, low price, no pollution, The preparation process is simple, the p...
