Abstract

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.

Description

technical field [0001] The invention relates to a preparation method of a photocurable white solder resist ink material with high catalytic efficiency, belonging to the technical field of ink materials. Background technique [0002] White solder resist ink is a layer of coating film printed on the LED circuit board to cover the surface circuit. This layer of solder resist ink has two main functions: one is solder resistance, that is, soldering on the LED lamp circuit board (PCB board) During the process, prevent unnecessary tin from adhering to the circuit and cause a short circuit; second, reflective, many LED light-emitting chips are directly welded on the circuit board, so the solder resist ink covering the circuit board also has a reflective effect. As we all know, white has the highest light reflection efficiency, which can greatly reduce light loss. However, after printing this layer of solder resist ink, there is a process of soldering. The temperature of the solderi...
