AI Technical Summary

Technical Problem

Existing zinc-magnesium-aluminum alloy die casting release agents suffer from uneven dispersion and agglomeration of composite powders, imperfect emulsification processes leading to uneven emulsion particle size, and insufficient long-term stability of the system, which affect the release effect and the surface quality of the castings.

Method used

A formulation consisting of polyetheramine-modified polysiloxane, barium titanate-montmorillonite-graphene quantum dot composite powder, polyethylene isostearate, pentaerythritol tetraisostearate, and polyimide resin is prepared by combining ultrasonic-microwave synergistic dispersion, gradient temperature-gradient speed-adjustment segmented emulsification, and bidirectional assisted stirring. A stable emulsion is formed through homogenization and filtration with appropriate mesh size.

Benefits of technology

It achieves uniform dispersion of composite powder, improves emulsion particle size uniformity and long-term stability, and enhances the high-temperature resistance, adhesion, and surface quality of the film layer, making it suitable for the high-temperature working conditions of zinc-magnesium-aluminum alloy die casting and industrial production.

Abstract

This invention belongs to the technical field of zinc-magnesium-aluminum alloy die-casting release agents, and discloses a zinc-magnesium-aluminum alloy die-casting release agent and its preparation method. The release agent comprises, by weight, polyetheramine-modified polysiloxane, barium titanate-montmorillonite-graphene quantum dot composite powder, polyethylene isostearate, pentaerythritol tetraisostearate, polyimide resin, and deionized water. The preparation method includes pre-stirring, ultrasonic-microwave synergistic dispersion, gradient temperature-gradient speed-adjustment segmented emulsification and bidirectional assisted stirring, homogenization, and filtration steps. This invention, through reasonable component compounding and optimized preparation process, effectively improves the dispersion uniformity of the composite powder and the long-term stability of the emulsion system, adapting to the working conditions of zinc-magnesium-aluminum alloy die casting, ensuring release effect and casting surface quality, and has good industrial application prospects.
