The invention relates to a dendritic self-initiating UV resin modified by sulfur-containing benzophenone and a preparation method thereof. A functional active group, a plurality of sulfur-containing benzophenone photoinitiating groups and a plurality of branched alkane groups; it has pigment bearing capacity, high solid and low viscosity and storage stability; The external BP type initiator has the defects of slow curing rate, easy yellowing of the coating, surface migration, strong volatility, large heat loss, generation of harmful substances and irritating odor; the dendritic self-initiating UV resin prepared by the present invention, It has excellent flexibility, adhesion, chemical resistance, heat resistance, aging resistance, oil resistance, abrasion resistance, pollution resistance, impact strength and odorless coating, and can be used for UV color floor coatings, UV wood coatings, UV alloy coatings, UV circuit board inks, UV plastic coatings. |
