Abstract

The invention provides an aluminum alloy water-based die-casting releasing agent. The aluminum alloy water-based die-casting releasing agent is prepared from the following components in percentage by weight: 40 to 70 percent of water, 2 to 5 percent of triethanolamine, 6 to 18 percent of water soluble synthetic ester, 14 to 25 percent of silicone emulsion and 8 to 12 percent of polyethylene wax emulsion. The invention also provides a preparation method of the aluminum alloy water-based die-casting releasing agent. The finished emulsion provided by the invention has the advantages of white color, uniformity, delicateness and no layering in centrifuging and standing; meanwhile, the aluminum alloy water-based die-casting releasing agent has good dispersity in water and is mixed with a small amount of ammonia and aqueous solution to rapidly form stable white emulsion; the white emulsion and other components of the releasing agent can form a stable balance system which is easy to blend.

Description

technical field [0001] The invention relates to the field of water-based release agents, in particular to an aluminum alloy water-based die-casting release agent and a preparation method thereof. Background technique [0002] As a high-quality metal with light weight, high strength and corrosion resistance, aluminum alloy is processed into various profiles through die casting (referred to as die casting), and is widely used in many industrial fields. The aluminum alloy material is heated and melted, injected into the mold cavity under high pressure in a liquid state, and the mold is opened and the top part is released in a short time. In order to ensure the smooth release of the product, a release agent must be sprayed on the surface of the mold cavity before injection. . In the aluminum alloy die-casting process, the release agent mainly plays three roles: (1) Before the metal liquid injection, by spraying the release agent, an isolation film is formed on the surface of th...
