Problems solved by technology

[0002] Aluminum or aluminum alloy materials are widely used. Due to their good comprehensive performance, they can be used in many fields, but their manufacturing costs are high, which limits the application of aluminum and aluminum alloy materials to a certain extent.
The currently used composite materials composed of resin or polymer materials and fillers can partially replace aluminum or aluminum alloy materials in some fields, but the products composed of resin or polymer materials as binders and fillers have high temperature resistance and thermal conductivity. And other physical properties are not ideal, and the production cost of this type of product is also high, so there are certain limitations in using it in some fields

Abstract

The invention relates to an aluminum enamel composite material and a production method, and the composite material comprises the following components by weight: 25-60% of aluminum enamel, 25-60% of aluminum or/and aluminum alloy and 10-30% of aggregate. The production method comprises the following steps: directly adding an aluminum enamel material in a fusion state in the aluminum or/and aluminum alloy, uniformly pugging at 400-600 DEG C, and then cooling and directly extruding to obtain a finished product or a parison. The aluminum enamel composite material has excellent comprehensive properties, the heat conduction coefficient is 70-200w/m.k through testing, the insulating property is good, and the aluminum enamel composite material can bear the high temperature at 400-500 DEG C, the anti-oxidation property is excellent; and the production cost is low with 15-20yuan/kg. The aluminum enamel composite material has the advantages of excellent comprehensive property and low production cost, is an ideal substitution material for aluminum and aluminum alloy, and can be widely used in many fields.

Description

technical field [0001] The invention relates to a composite material and a preparation method thereof, in particular to an enamel composite material and a preparation method thereof, and belongs to the technical field of composite materials. Background technique [0002] Aluminum or aluminum alloy materials are widely used. Due to their good comprehensive performance, they can be used in many fields, but their manufacturing costs are relatively high, which limits the application of aluminum and aluminum alloy materials to a certain extent. The currently used composite materials composed of resin or polymer materials and fillers can partially replace aluminum or aluminum alloy materials in some fields, but the products composed of resin or polymer materials as binders and fillers have high temperature resistance and thermal conductivity. And other physical properties are not ideal enough, and the production cost of this type of product is also on the high side, and there are ...
