Description

A kind of composite and preparation method thereof

Technical field

The present invention relates to advanced composite material (ACM) manufacture technology field, refer in particular to material and the manufacture craft thereof such as a kind of family or hotel's articles for daily use.

Background technology

The bottom of existing cooking appliance is all to adopt physical friction pressure strike-on and chemical brazing stainless steel, stainless iron, an iron plate to add thermal conductor conventionally, complex manufacturing technology, material thickness is subject to limiting to more than general subject wants 2.0MM, between heater and cooker parent, assemble the good metallic plate of one or more layers of heat conduction for heat conduction, thermal stress will will produce one by one gap in conjunction with place least closely at different materials molecule and even cause heater and even thermal conductive metal plate to come off between variant material layer. Or be connected with heater and occur the phenomenon of stress raisers to fracture at single or multiple lift METAL HEATING PROCESS layer. In general, this kind of heating properties with the cooker of compound bottom can reduce the thermal efficiency, and then extends the heat time, and this situation can be brought very large waste to the energy.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, provide a kind of conduct heat fast, heat conduction evenly, be subject to the impact of dilatancy little, advanced composite material (ACM) that the cooking appliance of stabilized structure is used.

For achieving the above object, technical scheme provided by the present invention is: a kind of composite, and described composite is binded and is formed by assistant metal material, mother metal, pressure rolling;

The preparation technology of above-mentioned material is:

First step: make assistant metal material

1), selection, selecting stainless steel or non-ferrous metal is the raw material of assistant metal material;

2), clean, adopt the degreasing agent for metal of the 5-10 ﹪ of 80-90 DEG C that the raw material surface of assistant metal material is cleaned up;

3), air-dry, air-dry processing is carried out in the raw material surface of assistant metal material, for subsequent use;

Second step: make mother metal

1), selection, select multiple layer metal or pressure rolling metal as mother metal raw material;

2), clean, adopt the degreasing agent for metal of the 5-10 ﹪ of 80-90 DEG C that mother metal raw material surface is cleaned up;

3), air-dry, air-dry processing is carried out in mother metal raw material surface, for subsequent use;

Third step; Clean surface dust and foreign material, remove the raw material of assistant metal material, dust and the foreign material on mother metal raw material surface;

The 4th step; The raw material of assistant metal material is spoted weld to mother metal raw material surface, and then successively by blowing, heating, clean surface, pressure rolling, heat treatment, smoothing, sawing sheet, moulding; Wherein, the control of pressure rolling parameter is: more than pressing outgoing gauge 1mm, when pressure rolling, material temperature is 300-550 DEG C, roller temperature 80-100 DEG C; Parameter control when heat treatment is 200 DEG C-300 DEG C, and the more than 0.5 hour air cooling of insulation is eliminated relevant stress.

Compared with prior art, this technique has the following advantages product structure:

The first, the polycrystalline substance of cooking appliance has adopted heat-transfer metal plate, magnetic conductive metal sheet to make that cooking appliance heating is faster, heat-conducting effect is better.

The second, the polycrystalline substance of cooking appliance adopts various metals material to make, and makes like this cooking appliance can not deform and come off in catch a cold/heat, simple in structure, cost is lower.

Three, the material that this technique is made is especially applicable to deep drawn and shaped article.

Detailed description of the invention

Below in conjunction with institute's drawings attached, the invention will be further described, and preferred embodiment of the present invention is: referring to accompanying drawing 1, to accompanying drawing 6, a kind of composite described in the present embodiment is binded and formed by assistant metal material 2, mother metal 1, pressure rolling;

1), selection its preparation technology is: make assistant metal material:, selecting stainless steel, stainless iron, copper, iron or non-ferrous metal is the raw material of assistant metal material; 2), clean, adopt the degreasing agent for metal of the 5-10 ﹪ of 80-90 DEG C that auxiliary material raw material surface is cleaned up; 3), air-dry, air-dry processing is carried out in auxiliary material raw material surface, for subsequent use; 1), selection make mother metal:, select aluminium, multiple layer metal or pressure rolling metal as mother metal raw material; 2), clean, adopt the degreasing agent for metal of 5-10 ﹪ of 80-90 DEG C by clean mother metal surface clean; 3), air-dry, air-dry processing is carried out in mother metal raw material surface, for subsequent use; When pressure rolling, first remove dust and the foreign material on auxiliary material raw material, mother metal raw material surface; Again auxiliary material raw material is spoted weld to mother metal surface, and then successively by blowing, heating, clean surface (compressed air), pressure rolling, heat treatment (can cancel this operation to the product of shallow moulding), smoothing, sawing sheet, moulding; Wherein, the control of pressure rolling parameter is: more than pressing outgoing gauge 1mm, when pressure rolling, material temperature is 300-550 DEG C, 80-100 DEG C of rolling roll temperature (surface temperature must be even); Parameter control when heat treatment is 200 DEG C-300 DEG C, and the more than 2 hours air cooling of insulation is eliminated relevant stress. The cooking appliance of making by the material of this programme can not deform and come off in catch a cold/heat, and technique is simple, production cost is lower.

The embodiment of the above is only the present invention's preferred embodiment, not limits practical range of the present invention with this, therefore the variation that all shapes according to the present invention, principle are done all should be encompassed in protection scope of the present invention.
