Title:
SILICONE RESIN FOR RAPID 3D PRINTING, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/037665
Kind Code:
A2
Abstract:
Disclosed are a silicone resin for rapid 3D printing, a preparation method therefor, and an application thereof, relating to the technical field of 3D printing materials. The preparation method of the silicone resin for rapid 3D printing comprises the following steps: S1, preparing monodisperse nano-silicon dioxide particles: hydrolyzing a silicon source aqueous solution to obtain a solution A; S2, preparing a silicone resin prepolymer: adding acetic acid and an alcohol aqueous solution into the solution A, adding a silicon source and a silane coupling agent having carbon-carbon double bonds, and carrying out hydrolysis and a copolymerization reaction to prepare an active prepolymer; cooling, adding a saturated sodium bicarbonate solution, and carrying out liquid separation, drying, and rotary evaporation to obtain the silicone resin prepolymer; S3, preparing the silicone resin for rapid 3D printing: uniformly mixing a photoinitiator with the silicone resin prepolymer in the S2 to obtain the resin for 3D printing. According to the present invention, by adjusting the proportion of the silicon source and the silane coupling agent having carbon-carbon double bonds, the curing speed is increased so as to achieve the purpose of rapid printing.
