Plate, the rolling that the method uses is routine techniques, becomes the platinum-niobium composite anode material of grade after setting roll rolling
Material meets dimensional requirement, and inventive feature is as follows:
First that compound plate is stand-by in the lower end of impact body by adhesive bonds, the face of the area >=compound plate of impact body
Long-pending；Horizontal positioned substrate on ground, compound plate, the area of substrate are placed by several support in the upper end of substrate
The area of >=compound plate, the height of several supports is equal and controls 3～10mm, in the upper ends of impact body
Medicine frame, the area of the area=impact body of medicine frame, even cloth explosive in medicine frame, the consumption of explosive is according to medicine frame
Length and width area control is 1.6～3.5g/cm2, bury 8 underground at arbitrary place of explosive#Industrial detonator, by 8#Industry
Blasting cap initiation explosive, prepares platinum-niobium composite blank；Platinum-niobium composite blank is rolled out into grade by roll
Platinum-niobium composite anode materials, above-mentioned area refers to the product of length and width.
Owing to using techniques described above scheme, the present invention produces following beneficial effect:
1, the explosive welding mode that the present invention utilizes impact body to load achieves the smelting of platinum metal layer and metal suboxide layer
Gold combines, and improves bond strength；Platinum-niobium the composite anode materials of grade is prepared into again by rolling mode,
The problem solving platinum metal layer and the combination of metal suboxide layer thickness, and make its bonded area be opened up further
Exhibition.
2, serious " de-platinum " problem the most firmly produced in background technology is solved because of bond strength.
3, the explosive welding of the present invention is suitable for different work condition environment so that platinum metal layer realizes with metal suboxide layer
Metallurgical stratiform combines and improves bond strength, can answering directly as the impressed current cathodic protection of boats and ships
Heyang pole uses, and improves the reliability of platinum-niobium composite anode materials and increase the service life.

Detailed description of the invention
A kind of method that the present invention is explosive welding and platinum-niobium composite anode materials is prepared in rolling, the method energy
Platinum-niobium composite blank explosive welding obtained obtains into the platinum-niobium composite anode material of grade by rolling mode
Material.
The present invention uses impact body, compound plate and substrate in explosive welding, wherein impact body be copper plate,
Compound plate be platinum sheet, substrate be niobium plate.
The rolling that the present invention uses is routine techniques, and this rolling is realized by rolling mill roll, sets roll rolling
The platinum of rear one-tenth grade-niobium composite anode materials meets dimensional requirement.
In conjunction with Fig. 1, due to compound plate 5 thinner thicknesses≤1mm, therefore first compound plate 5 is existed by adhesive bonds
The lower end of impact body 3 is stand-by, the length and width area of the length and width area >=compound plate 5 of impact body 3.In detonation load
During loading, compound plate can reach maximal rate rapidly, but the action time of pressure is directly proportional to the thickness of multiple material,
Due to compound plate thinner thickness, pressure declines very fast, vibration occurs, it is also possible to go out when making compound plate move downward
Now slow down phenomenon, cause the uneven of collision process, unstable.Relatively small in compound plate mass area ratio
In the case of, impact body now plays and solves the composite quality caused uneven, unstable of collision process relatively
The effect of the problem that difference and compound plate may be punctured by injecting stream again or damage.
Horizontal positioned substrate 7 on ground 8, compound plate 5, base are placed by several supports 6 in the upper end of substrate 7
The length and width area of the length and width area >=compound plate 5 of plate 7, the height of several supports 6 equal and control 3～
10mm, in the upper ends medicine frame 2 of impact body 4, the length and width face of the length and width area=impact body 4 of medicine frame 2
Long-pending, even cloth explosive 3 in medicine frame 2, the consumption of explosive 3 according to the length and width area control of medicine frame 2 1.6～
3.5g/cm2, bury 8 underground at arbitrary place of explosive 3#Industrial detonator 1, by 8#Industrial detonator 1 detonating charge 3
Platinum-niobium composite blank 10 can be prepared.
Finally platinum-niobium composite blank 10 is rolled by roll 9 the compound sun of platinum-niobium that can prepare into grade
Pole material 11, the platinum-niobium composite anode materials 11 becoming grade can be sheet material, or tubing, or bar.
Following table be according to the present invention for a kind of embodiment.
For open the present invention's and the embodiment selected in this article, it is suitable to be presently considered to be, but answers
Solve: it is contemplated that include all changes belonging in the scope of the invention and improvement.
