Abstract

The invention discloses a high-temperature-resistant toughened light-cured resin composition and a preparation method thereof. The composition contains the following raw materials: acrylic resin, epoxy resin, an active diluent, a free radical initiator 1, a free radical initiator 2, a cationic initiator, polyol, a leveling agent, an antifoaming agent, a wetting dispersing agent, nano-core-shell rubber, nano-silicon oxide and a pigment. According to the resin composition, the curing rate of high-temperature-resistant light-cured resin can be effectively increased, and the initial strength of a product is greatly enhanced; furthermore, the material further has relatively high tenacity, so that the operations of punching, screw drilling and the like can be realized on a sample. Therefore, the high-temperature-resistant toughened light-cured resin composition has the characteristics of high curing efficiency and initial strength, excellent high temperature resistance, good tenacity and stable dimension.

Description

technical field [0001] The invention relates to the technical field of photocurable materials, in particular to a novel high temperature resistant and toughened photocurable resin composition and a preparation method thereof. Background technique [0002] Photocuring technology is an efficient, environmentally friendly, energy-saving, high-quality material surface treatment technology, known as a new technology for the green industry in the 21st century. Photocuring resin is the most important part of photocuring technology. It is composed of resin monomers and prepolymers, contains active functional groups, and can be polymerized by photoinitiators under ultraviolet light irradiation. [0003] In recent years, due to the strong support of the state, photocuring 3D printing technology has developed by leaps and bounds. Correspondingly, photosensitive resins have also achieved unprecedented development. People have higher requirements for 3D printing. And students, including...
