Embodiment 1

[0027] Add water 51.5%, triethanolamine 1%, Momentive silicone oil emulsion 334-50 25%, Wacker silicone wax emulsion WACKERE32 10%, BASF polyethylene wax emulsion WE-7 12%, BIT-20 fungicide 0.5%.

[0028] The preparation process is as follows: add triethanolamine and part of water into a clean container, add Momentive silicone oil emulsion 334-50, WACKER silicone wax emulsion WACKER E32 and BASF polyethylene wax emulsion WE-7 12% in sequence under high-speed stirring, and keep stirring After a period of time, add the remaining water and BIT-20 bactericide, and stir evenly at a low speed. The finished emulsion is white, uniform and fine, and it does not separate after centrifugation.

[0029] Among them, water is used as a solvent; triethanolamine is used as an antirust agent; Momentive silicone oil emulsion 334-50 plays the role of mold release and lubrication; WACKER silicone wax emulsion WACKER E32 plays the role of lubrication, assisting mold release and improving the stabil...

Embodiment 2

[0033] Others are the same as Example 1, except that the proportion is: add water 70.3%, triethanolamine 0.5%, Momentive silicone oil emulsion 334-50 14%, Wacker silicone wax emulsion WACKER E32 8%, BASF polyethylene wax emulsion WE -7 7%, BIT-20 fungicide 0.2%.

Embodiment 3

[0035] Others are the same as Example 1, except that the proportion is: add water 63%, triethanolamine 0.7%, Momentive silicone oil emulsion 334-50 18%, Wacker silicone wax emulsion WACKER E32 9%, BASF polyethylene wax emulsion WE -7 9%, BIT-20 fungicide 0.3%.

Abstract

The invention provides a water-based mold release agent applied to an aluminum alloy die casting. The water-based mold release agent comprises the following components of, by weight percentage, 51.5%to 70.3% of water, 0.5% to 1% of triethanolamine, 14% to 25% of silicone oil emulsion, 8% to 10% of silicon wax emulsion, 7% to 12% of polyethylene wax emulsion and 0.2% to 0.5% of a sterilizing agent. The invention also provides a preparation method of the water-based mold release agent applied to the aluminum alloy die casting. The preparation method provided by the invention can greatly increases the rate of finished products in a surface after-treatment process, alleviates the burthen of a washing procedure, effectively increases the rate of finished products of surface treatment, shortensthe unplanned shutdown time, remarkably lowers the cost and maintains the stability of the water-based mold release agent, and the water-based mold release agent has quite good compatibility and affinity to other ingredients in a system.

Description

technical field [0001] The invention relates to the field of water-based release agents, in particular to a water-based release agent applied to aluminum alloy die castings 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. . [0003] In the die-casting process, the release agent plays three roles: (1) before the metal liquid injection, by spraying the release agent, an isolation film is formed on the surface of the ...
