▎ 摘  要

NOVELTY - Aqueous mold release agent comprises 14-20 pts. wt. polyethylene wax, 4-7 pts. wt. polyethylene glycol 2000, 2-6 pts. wt. stearic acid, 1-4 pts. wt. Tween 60 (RTM: Polyoxyethylene (20) sorbitan monostearate), 1-4 pts. wt. modified graphene, 1-3 pts. wt. fullerene, 1-3 pts. wt. stearate, 1-2 pts. wt. titanium dioxide, 0.8-2 pts. wt. sodium alginate, 0.5-1.2 pts. wt. triethanolamine, 0.4-1 pts. wt. soft wood powder, 0.02-0.1 pts. wt. magnesium hydrogen phosphate trihydrate, and 50-70 pts. wt. deionized water. USE - The aqueous mold release agent is useful for alloy die casting of 3C electronic product. ADVANTAGE - The aqueous mold release agent has good stability and good demolding effect, effectively improves the demolding effect, improves the lubricating performance, reduces the surface friction of the casting, improves the separating demolding capability, and makes there will be no pull marks and no pores during demolding. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing aqueous mold release agent.
