Photosensitive resin for solid materials and preparation method thereof

Abstract

The invention discloses a photosensitive resin for solid materials and a preparation method thereof. The photosensitive resin for solid materials is composed of the following components in percentage by weight: 30-60% of low polymer, 20-40% of monomer, 1-10% of photoinitiator, 10-20% of diluter, 0.1-4% of defoaming agent, 0.1-4% of leveling agent and 0.1-5% of nano silicon dioxide. The preparation method comprises the following steps: (1) proportionally preparing raw materials; and (2) uniformly mixing the components to prepare the photosensitive resin material for solid material printing, wherein the viscosity of the photosensitive resin material is 20-30cp. The photosensitive resin for solid materials is a precedent in China. Compared with like products abroad, on the premise of ensuring various properties, the cost is greatly lowered, the physical mechanical properties of the solid model are enhanced, and the photosensitive resin can be used for manufacturing molds for producing small-batch molding part products, thereby satisfying the use demands of more users at home and abroad.

Description

technical field [0001] The invention relates to a photosensitive resin that can be used for solid materials, and more specifically relates to a photosensitive resin for solid materials of a photocurable 3D printer, which belongs to the technical field of photocurable materials. Background technique [0002] The current inkjet UV curing molding process for 3D printing is to spray the photosensitive resin that can be UV cured by inkjet method, cure it by UV light irradiation, and then stack it layer by layer to form the required model. Photosensitive resins are resins that obtain a certain structural strength after being cured by UV irradiation, and are divided into solid materials and support materials. At present, there is no such photosensitive resin for solid materials that meets the requirements in my country, and they are all monopolized by foreign countries. 3D printing technology is very limited.
