Metal additive for aluminum alloy

Abstract

The invention belongs to the field of metal additives, and particularly relates to a metal additive for aluminum alloy, and the metal additive for aluminum alloy comprises the following specific components: 10-50 parts of metal powder, 1-5 parts of stearic acid, 1-3 parts of a potassium salt and 1-10 parts of epoxy resin. In the prior art, an additive is extruded into a block shape so as to be convenient to transport and put, but if the extrusion is too sufficient, the additive cannot be quickly melted and mixed in the dissolving process so as to cause poor production effect, but if the extrusion is insufficient, the additive is crushed and dispersed in the transportation process so as to cause the phenomena of waste and inconvenient putting; the outer side of the extruded additive is covered with a layer of epoxy resin, the additive does not need to be extruded too sufficiently, it can also be guaranteed that the additive cannot be scattered before being put in, and when the aluminum alloy is manufactured, the epoxy resin can be decomposed into carbon dioxide and water due to the high temperature effect, so that preparation of the aluminum alloy cannot be affected.

Description

technical field [0001] The invention belongs to the field of metal additives, in particular to a metal additive for aluminum alloys. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in the industry. Compared with ordinary carbon steel, it has lighter weight and corrosion resistance; [0003] Metal additives are prepared by mixing metal powder, stearic acid and potassium salt, and then extruding them into blocks. When producing aluminum alloys, metal additives need to be put into it to adjust the composition of aluminum alloys. , and the extruded block shape can be convenient for transportation and delivery; [0004] A Chinese patent with publication number CN105861869B discloses a metal additive for aluminum alloy smelting. Flux, the flux is the waste slag produced in the production process of aluminum-titanium-boron alloy, the sum of each component is 100%. In the present invention, the waste slag is crushed and sc...

Problems solved by technology

[0005] Existing metal additives are generally directly extruded, but if the extrusion is too sufficient, it is easy to cause the additives to fail to melt and mix quickly during the dissolution process, resulting in poor production effect, but if the extrusion is not sufficient, it will lead to In the process, the additives are crushed and scattered, which is easy to cause waste and inconvenience in putting in;
