Abstract

The invention discloses organically soluble photosensitive resin after being cured, and a preparation method and a dissolving method thereof, which belong to the technical field of high molecular materials. Based on that the total mass of the resin is 100%, the resin comprises the following components in percentage by mass: 40-60% of N,N'-methylene bisacrylamide monomer, 10-30% acrylate monomer, 5-10% of polyethylene pyrrolidone thickening agent, 10-20% of methyl acrylic anhydride cross-linking agent and 1-4% of free radical type photopolymerization initiator. The preparation method comprises the following steps: firstly, mixing the free radical type photopolymerization initiator, the N,N'-methylene bisacrylamide monomer, the acrylate monomer and the methyl acrylic anhydride cross-linking agent, and further adding polyethylene pyrrolidone. The cured resin can be dissolved when being immersed into a mixture solution of N,N-dimethylformamide and butyl amine. The resin functions as a support layer and a sacrificial layer in three-dimensional circuit manufacturing procedures, and is a critical material for realizing three-dimensional circuits.

Description

Technical field [0001] The invention relates to an organic soluble photosensitive resin after curing, a preparation method and a dissolving method, in particular to a photosensitive resin that can be polymerized by visible light (wavelength 405nm) and is organic soluble after curing, a preparation method and a dissolving method Specifically, it is a cured organic soluble photosensitive resin used for visible light microlithography molding of three-dimensional circuits, a preparation method and a dissolution method, and belongs to the technical field of polymer materials. Background technique [0002] With the continuous promotion of light-curing molding process, light-curing molding has gradually been widely used in rapid casting, rapid mold and other industries because of its ability to mold arbitrarily complex structures and high-precision parts. Therefore, the requirements for various properties of photosensitive resins are also increasing. To improve, most of the light-curing...
