Embodiment 1

[0022] The method for connecting and sealing gold, titanium and silver materials comprises the following steps:

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

[0024] Step 2: Use the hoarding board to enclose the joint surface formed by the three materials of gold material 1, silver material 2, and titanium material 3 into a space area, and apply a 1mm 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 gold, nickel, and silver materials, comprising the following steps:

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

[0029] Step 2: Use the hoarding board to enclose the joint surface formed by the three materials of gold material 1, silver material 2, and nickel 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;

[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] The method for connecting and sealing gold, zinc and silver materials comprises the following steps:

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

[0034] Step 2: Use the hoarding board to enclose the joint surface formed by the three materials of gold material 1, silver material 2, and zinc 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;

[0035] Step 3: After 15 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 method for connecting and sealing gold and silver materials, which comprises the following steps: under normal temperature conditions, a ductile metal (3) is mechanically embedded in the gap between the two materials of gold (1) and silver (2), Use the hoarding board to enclose the joint surface formed by the three materials of gold (1), ductile metal (3) and silver (2) into a space area, and pour high-performance silicone structural adhesive on the substrate in the space area . The invention has good connection and sealing effect, and the whole production is carried out under the normal temperature condition, the production process is simple, the operation 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 of dissimilar metal materials, in particular to a connection and sealing method of gold and silver 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 "gold + silver" two-material connection structure. At present, the connection of gold and silver 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 "gold + silver" has p...
