Abstract

The invention discloses a polysiloxane resin for photosensitive solder resist white oil and its preparation method and application. The preparation method comprises the following steps: (1) synthesizing a polysiloxane prepolymer; (2) synthesizing a photosensitive polysiloxane (3) synthesizing alkali-soluble polysiloxane resin, that is, the polysiloxane resin for photosensitive solder resist white oil. The use of the alkali-soluble polysiloxane resin of the present invention in photosensitive solder resist white oil has excellent black non-sensitivity scratch resistance, and at the same time solves the problem that the acrylic resin-type solder resist white oil coating in the current market is prone to black non-sensitivity scratches question.

Description

technical field [0001] The invention relates to the technical field of photosensitive materials, in particular to a method for preparing polysiloxane resin for photosensitive solder resist white oil by copolymerization of vinyl silicone oil and acrylates and its application. Background technique [0002] With the advancement and development of electronic technology, in addition to improving the display effect of the picture, LED TVs also need to effectively improve the smearing of dynamic pictures. Therefore, LED TVs need to pursue higher brightness and richer colors. In terms of design, it is necessary to change from the previous side-illuminated light source to a rear-projection full-board light source. By coating an alkali-soluble photosensitive composition on a substrate such as a printed circuit board and curing it with light or heat, it can be widely used as an insulating layer such as a solder mask, and the photocurable composition is used as a light-emitting diode ( ...
