Problems solved by technology

However, due to the composite material formed by elemental metal and organic compound, the metal reinforcement material and the organic matrix material do not dissolve each other, but the metal atomic groups are dispersed in the organic matrix material, which can easily cause the instability of the performance of this type of material, especially for those Metal-organic composite materials that often work in a liquid state (such as copper wax composite temperature-sensing wax), because the density of the metal is greater than the density of the organic matter, it is easy to cause the metal reinforcement material to be precipitated or partially separated from the organic matrix material, resulting in The performance of this type of composite material is very unstable
Using this kind of composite material with very unstable performance in various components will directly affect the performance stability and service life of components, and bring losses to production and life.
For example, copper powder and wax are directly used to make composite temperature-sensing wax for the manufacture of engine temperature-sensing devices. Since the copper powder in this composite temperature-sensing wax is easy to separate from the wax, it is very easy to cause the performance of the temperature-sensing device to be unstable. Affect the performance of the engine, and even cause the engine to be scrapped

Abstract

The invention discloses a method for processing a metal organic composite material with stable functions. By adopting the technology of coating micro-nanometer metal powder with a cross-linking agent, the problem that the metal of metal organic substance insoluble in organic substance is deposited and separated from the organic base substance is effectively solved, thus effectively preparing the metal organic composite material with the stable functions. The preparation method comprises the steps of coating micro-nanometer metal powder with the cross-linking agent; thoroughly mixing organic base material with the reinforcing material of the cross-linking agent coated metal powder; and forming. The invention aims to prepare the metal organic composite material with the stable functions.

Description

(1) Technical field [0001] The invention belongs to the field of functional composite materials, in particular to a processing method of metal-organic composite materials with stable functions. (2) Background technology [0002] Organic compounds generally have poor thermal and electrical properties, but many organic compounds have low melting points, large expansion coefficients, and good fluidity; compared with organic compounds, metals have superior thermal and electrical properties, but general metals It has the characteristics of high melting point, small thermal expansion coefficient and strong coordination ability. Composite materials formed by compounding simple metals and organic compounds, such as metal-plastic composite materials prepared by mixing plastics and metals, have adjustable and excellent electrical or thermal conductivity, and have been widely used in production and life. However, due to the composite material formed by elemental metal and organic comp...
