The invention relates to a method for preparing a high
catalytic efficiency-type light-cured white solder-
resist ink material, which belongs to the technical field of an ink material. The technical scheme of the invention adopts
algae to extract photosensitive
protein, under the
irradiation of appropriate light, the
algae protein molecules are excited by absorbing a certain amount of energy, the excited
algae protein molecules have poor stability, and need to emit particles and energy to return to an unexcited
ground state, at the same time, the technical scheme of the method fully modifies and fills the algae protein by using
plant white
pigment, the
exposure intensity and the sensing property of the algal protein to the
white light can be improved, and the reaction performance of the inkmaterial for preparing the white solder-
resist ink material can be improved; and the method overcomes the problem of difficult solidification of a white
system by using a white
plant source
pigment modified
photosensitizer material, the strong reflection effect of white to light is reduced, the intensity of the
ultraviolet light received in the
system is greatly enhanced, so that the white
coating is completely cured, especially the deep curing of the
coating, and a high-efficiency photoinitiating
system is prepared.
