Problems solved by technology

This explosion-proof material has been immersed in the container medium for a long time, and its application range is limited due to the material itself.
In addition, the current explosion-proof materials generally use mechanical cutting technology to cut slits on the metal foil, and then stretch it. The cutting waste and particles generated during cutting are unfavorable for the use of explosion-proof materials.

Embodiment 1

[0007] The tin-copper alloy melted and cast ingot is rolled into a 0.03mm thick tin-copper alloy foil, the mass percent of each element in the tin-copper alloy foil is 3.5 tin, 3.0 zinc, 0.2 nickel, copper balance, and the sum of impurities is not more than 0.2 . The tin-copper alloy foil is slit with laser equipment, and stretched to form a mesh explosion-proof material. The cutting equipment used is a laser slitting machine, the power of the laser head of the slitting machine is 100 watts, and the cutting speed is 200mm / s. Stretch forming is operated by a stretching machine, and the stretched mesh is at an angle of 70-90 degrees to the original plane.

Embodiment 2

[0009] The operation of Example 1 was repeated, except that the mass % of certain elements was modified to 8.0 for tin and 0.3 for zinc. The thickness of the tin-copper alloy foil is modified to 0.02mm.

Embodiment 3

[0011] The operation of Example 1 was repeated, except that the mass % of certain elements was modified to 6.0 tin and 0.3 zinc, and the thickness of the tin-copper alloy foil was modified to 0.08 mm.

Abstract

The invention provides a tin and copper alloy explosion-proof material and a preparation method thereof. The preparation method of the explosion-proof material comprises the following flows of: performing ingot casting on tin and copper alloy, rolling tin and copper alloy foil, performing joint-cutting with a joint-cutting machine and stretching to form a meshed material. The tin and copper alloycomprises the following elements in percentage by mass: 3.5 to 8.0 percent of tin, 0.3 to 3.0 percent of zinc, 0.2 percent of nickel, the balance of copper and less than or equal to 0.2 percent of total impurities, wherein the thickness of the tin and copper alloy foil is between 0.012 and 0.10 millimeter, laser beams emitted by the joint-cutting machine are basically perpendicular to the moving direction of titanium alloy foil, the total power for emitting laser radial is between 100 and 1,000 watts, and 3 to 5 laser radial emitting devices which are arranged side by side are used to performjoint-cutting.

Description

technical field [0001] The invention relates to an explosion-proof material, especially a tin-copper alloy explosion-proof material and a preparation method thereof. Background technique [0002] In the storage and transportation containers of flammable and explosive liquid and gaseous hazardous chemicals, in order to prevent the medium from burning and exploding due to accidents such as static electricity, open flames, gunshots, etc., it is necessary to fill a kind of mesh explosion-proof material in the storage and transportation containers. Material. Existing explosion-proof materials are made of aluminum alloy. This explosion-proof material has been immersed in the container medium for a long time, and its application range is limited due to the material itself. In addition, the current explosion-proof materials are generally made by cutting slits on the metal foil by mechanical cutting technology, and then stretched. The cutting waste and particles generated during cu...
