The invention belongs to the technical field of
aviation equipment maintenance, and particularly relates to a
cleaning agent suitable for an aircraft
brake pad and a preparation method of the
cleaning agent. The
cleaning agent provided by the invention comprises a continuous-phase
gel matrix and two-phase microcapsules dispersed in the continuous-phase
gel matrix, the continuous phase
gel matrix comprises the following components in percentage by weight: a main
solvent, a penetrant, a chelating agent, a gelling agent, a
corrosion inhibitor and the balance of deionized water; a shell layer of the biphase microcapsule is a
mechanical force responsive polymer shell, and an inner core of the biphase microcapsule is a penetration
softening agent and a volatile stripping agent which are not mutually dissolved. Through a unique'gel matrix + two-phase microcapsule 'synergistic
system, oil stains can be quickly permeated and dissolved, carbonized particles and
metal oxides can be disintegrated, and cleaning is thorough. The two-phase microcapsules realize stepped removal of stubborn carbonized
dirt, namely
permeation softening and pneumatic stripping, so that the cleaning efficiency is greatly improved, and the physical wear of a matrix is reduced.
