The present invention relates to a composite material whose main component is metal, and more particularly to a composite material characterized by using a material in which the surface of metal particles is coated with a liquid or powdered synthetic resin. Traditionally, metal parts have been manufactured by cutting the metal material using machine tools to obtain the desired shape, by melting the metal and pouring it into a mold, by forging, or by using powder. A method that has been used to date is to mix the metal with a binder, press-form it, and then sinter it to melt the surfaces of the powdered metals and bond them together. However, all of these conventional techniques require expensive mechanical equipment and long hours of work, and it has been a long-held desire of the industrial world to obtain molded products with metallic properties at a lower cost and in a shorter time. there were. The present invention corrects all of the drawbacks and problems of the prior art, and satisfactorily achieves the desires of the prior art. Hereinafter, the present invention having such characteristics will be specifically explained in detail. First, a material is produced by coating metal powder with a synthetic resin or a natural material that is in liquid or powder form before hardening. The metal powder used here is one that meets the final purpose of use. That is, when electrical conductivity is required, it is possible to select from all metal powders and powders, such as good electrical conductors such as copper powder. As a coating material, any synthetic resin that can be coated depending on the purpose can be used, but materials that have sufficient strength after curing are preferred, such as epoxy resin, phenol resin, polyethylene resin, nylon resin, ABS resin, etc. Synthetic resins are suitable for use, but depending on the final purpose of use, it is not necessarily limited to synthetic resins; for example, adhesives such as starch or water glass can also be used. In any case, the purpose of this material can be achieved when the metal powder coated on the coating material functions as a molded article or as a coating material for adhesive purposes, and at the same time has metallic properties. The gist of the present invention is to use the above materials before the coating material is cured. Pressure is applied to the materials to bring the metals into contact. The objective is to impart metallic properties to the pressurized part. The pressurization here refers to heating and pressurizing with a hot press molding machine using a mold made of metal or gypsum. In this case, by changing the heating temperature, pressure, and molding time. Molded products can be obtained according to needs. Below, some examples of composite materials having metal as a main component according to the present invention are listed.

[Example 1] An example of a material coated with a synthetic resin of 35% or less of the amount of metal particles. (A) Heat the material to a temperature at which the synthetic resin melts or gels, and simultaneously apply a pressure of 300 to 1200 kg/J to bring the metals into contact with each other, sealing the space with the synthetic resin, and making the metals contact each other. As a result, we were able to obtain a molded product with the electrical and thermal properties of the electrically and thermally conductive metal itself. CB) During the above molding, a pressure of 20 to 300 kg/cd was applied to bring the metals into contact with each other, and a part of the space was filled with 1 synthetic resin, and the metal particles were connected and fixed.
A high-quality molded product with air permeability and electrical and thermal conductivity was obtained.

[Example 2] An example of a material coated with a synthetic resin of 20% or less of the amount of metal particles. Apply pressure of 1 to 30 kg/J during the above molding. As a result of filling and fixing the spaces between the metal particles with synthetic resin without allowing the metal particles to come into contact with each other, high-quality molded products such as crafts with the luster and properties unique to metals were obtained on the surface of the molded product.

[Example 3] Two or more layers of different coated materials are stacked, and metal or other powders are brought into contact with each other. As a result of heating and pressurizing and molding (same as A and B of Example 1), a good composite molded product with two or more layers was obtained (see drawing). Another feature of the present invention is that even for items that require soldering but cannot be soldered, such as carbon ceramics, it is possible to solder the steel parts by making one layer of copper. be.
