The invention belongs to a non-cohesive gel coating, and provides a polyethylene surface composite non-cohesive gel coating, a preparation method thereof, a mold and an actuator, aiming at the technical problems that the packaging quality is influenced, the packaging efficiency is reduced and the overall assembly efficiency of an airplane is reduced due to the fact that the tail end of an automatic robot gluing actuator is adhered to an uncured sealant in the assembly process of the airplane. Fluorinated silicon dioxide powder and micron-sized hollow glass ball filler are respectively prepared, mixed with polyvinylidene fluoride powder and mixed and dispersed in a polar solvent to obtain a micro-nano composite solution, and the micro-nano composite solution is sprayed on a polyethylene matrix subjected to surface texture treatment to obtain the polyethylene surface composite non-cohesive gel coating, so that the surface contact area is reduced, and the adhesion resistance is improved. The super-hydrophobic su
