Abstract
A flat-pressing manufacturing method of a bionic adhesive structure based on a micro through-hole nickel-based mold is disclosed. The method includes the following steps: preparing a nickel-based mold with a micro through-hole array; placing the nickel-based mold on an elastic pad in a magnetic mold closing system; coating a liquid prepolymer uniformly on a backing, and placing a side of the backing coated with the liquid prepolymer on the nickel-based mold, covering a sealing diaphragm on the backing to separate a cavity into an upper chamber and a lower chamber, and performing a vacuum treatment on the lower chamber and an inflation treatment on the upper chamber to apply a uniform pressure on the backing layer and achieve a full filling of prepolymers with different viscosities; and after the filling is completed, curing and demolding to obtain the bionic adhesive structure.
