Embodiment Construction

[0023] First, the preferred ranges of the components of the cement of the present invention will be illustrated based on the following proportional formula:

[0024] AlN:Mg:H 2 O=8:3:12 (coefficient ratio)

[0025] =328:72:216 (weight ratio)

[0026] =53% by weight: 12% by weight: 35% by weight

[0027] The molecular weight of AlN is 41 (the sum of atomic weights), multiplied by 8 to get 328. The atomic weight of Mg is about 24, multiplied by 3 to get 72. h 2 The molecular weight of O is 18, multiply by 12 to get 216.

[0028] Therefore, when 8:3:12 (coefficient ratio) is converted into a weight ratio, it is expressed as 328:72:216. When converted into a percentage, it is 53% by weight: 12% by weight: 35% by weight. In other words, the proportion of AlN is preferably 53% by weight, the proportion of Mg is preferably 12% by weight, and the proportion of H 2 The proportion of O is preferably 35% by weight. However, these ratios can be enlarged in practical applications....

Abstract

The present invention provides a bonding agent for metals or ceramics, which contains 0.25% to 18.0% by weight of magnesium powder, 25% to 50% by weight of a solvent containing hydroxyl groups in its molecular structure, and the balance of AlN powder. When the components of the above-mentioned cement are mixed and placed under certain conditions, these components will react to generate a large amount of heat of reaction. When the base material or the parts to be bonded to it are aluminum alloys, the dense oxide film usually formed on its surface will hinder the bonding between them, and the above-mentioned reaction heat can make the layer that hinders the bonding between the base metal and the parts The dense oxide film is thermally damaged.

Description

technical field [0001] The present invention relates to a bonding agent based on an inorganic component for joining metal or ceramic parts, and more particularly, the present invention relates to a bonding agent for metal or ceramic parts whose curing is accelerated by heating, and to a A method of joining metal or ceramic parts with an admixture. Background technique [0002] Known methods of joining metal or ceramic parts are welding (brazing) or joining by organic adhesives. [0003] The bonding method using an organic adhesive requires expensive equipment to maintain a proper working environment because it uses an organic solvent such as toluene. Furthermore, it requires expensive equipment to dispose of contaminated organic solvents. [0004] Soldering will not cause any environmental problems and disposal of waste liquid, but it is necessary to heat the base material with solder and the parts to be joined to the melting temperature of the solder in a vacuum furnace (...
