Embodiment 1

[0022] A method for connecting and sealing magnesium, copper, and aluminum materials, comprising the following steps:

[0023] Step 1: If figure 1 As shown, under normal temperature conditions, the copper material 3 with a thickness of 2mm is embedded in the gap between the connected magnesium material 1 and the connected aluminum material 2 by cold pressure welding;

[0024] Step 2: Use the hoarding board to enclose the joint surface formed by the three materials of magnesium material 1, aluminum material 2, and copper material 3 into a space area, and apply a 2mm thick polyurethane primer on the substrate of the space area as a primer Coating to remove the oxide layer residing on its surface;

[0025] Step 3: After 10 minutes, pour high-performance silicone structural glue on the substrate of the enclosed space area, and the product is ready.

Embodiment 2

[0027] A method for connecting and sealing magnesium, chromium, and aluminum materials, comprising the following steps:

[0028] Step 1: If figure 1 As shown, under normal temperature conditions, the chromium material 3 with a thickness of 4mm is embedded in the gap between the connected magnesium material 1 and the connected aluminum material 2 by cold pressure welding;

[0029] Step 2: Enclose the joint surface formed by the three materials of magnesium material 1, aluminum material 2, and chrome material 3 with a hoarding board to form a space area, and apply a 5mm thick polyurethane primer on the substrate of the space area as a primer Coating to remove the oxide layer residing on its surface;

[0030] Step 3: After 15 minutes, pour high-performance silicone structural glue on the substrate of the enclosed space area, and the product is ready.

Embodiment 3

[0032] A method for connecting and sealing magnesium, zinc, and aluminum materials, comprising the following steps:

[0033] Step 1: If figure 1 As shown, under normal temperature conditions, the zinc material 3 with a thickness of 3 mm is embedded in the gap between the connected magnesium material 1 and the connected aluminum material 2 by cold pressure welding;

[0034] Step 2: Use the hoarding board to enclose the joint surface formed by the three materials of magnesium material 1, aluminum material 2, and zinc material 3 into a space area, and apply a 3mm thick polyurethane primer on the substrate of the space area as a primer Coating to remove the oxide layer residing on its surface;

[0035] Step 3: After 12 minutes, pour high-performance silicone structural glue on the substrate of the enclosed space area, and the product is ready.

Abstract

The invention discloses a magnesium and aluminum material connecting sealing method. The method comprises the following steps that under the normal temperature condition, ductile metal (3) is embedded into a clearance part of a magnesium material (1) and an aluminum material (2) in a mechanical mode, a spatial region is formed by enclosing joint faces of the magnesium material (1), the ductile metal (3) and the aluminum material (2) through an enclosing plate, and a high-performance silicone structural adhesive is poured on a substrate in the spatial region. According to the magnesium and aluminum material connecting sealing method, a good connecting sealing effect is achieved, the whole production is conducted under the normal temperature condition, the production technology is simple, the operating environment is improved, the labor intensity is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to a connection and sealing method for dissimilar metal materials, in particular to a connection and sealing method for magnesium-aluminum materials. Background technique [0002] In recent years, the application of dissimilar metal connections has become more and more widespread. A single metal itself does not have all the physical, chemical and mechanical properties required for the application, but dissimilar metals can meet the needs, and can save materials, reduce costs, and save energy. [0003] In industrial production at home and abroad, there are more and more products using "magnesium+aluminum" two-material connection structure. At present, the connection of magnesium and aluminum mainly adopts mechanical connection methods such as riveting, bolting and welding. The quality of the riveted or bolted joint is high, the shape of the joint is limited, and the direct riveting or bolted connection of the two materials of "mag...
