Natural-based modified light-cured resin and preparation method thereof

Abstract

A natural-based modified light-cured resin comprises the following components: epoxy tung oil, acrylate, low-molecular-weight epoxy resin, a polymerization inhibitor, maleic anhydride and an additive. The resin is prepared through a special manufacturing process, and the defect that light-cured resin prepared through a conventional preparation process is poisonous and contains lots of poisonous substances is overcome, so that not only is human health protected, but also environmental harmonious development is promoted; raw material obtain manners are increased, the production cost of manufacturing enterprises is reduced, and risks caused by little raw material purchase manners are reduced; through the great use of the plant raw materials, the degradability of the produced resin is improved, and especially in a dental treatment process, green, nontoxic, environment-friendly and health concepts are better reflected.

Description

technical field [0001] The patent of the present invention relates to the technical field of a light-curable resin and its preparation method, especially a natural-based modified photo-curable resin and its preparation method. This invention adopts a special preparation method, through the increased use of natural base, It reduces the dependence on petrochemical products in the prior art, such as polyurethane, polyester, epoxy compound or polyether, etc., not only improves the degradability of the light-cured resin produced, but also greatly reduces the purchase cost of raw materials , broadened the procurement channels, and played a positive role in protecting the ecological environment and reducing the risk of corporate raw material procurement. Background technique [0002] Photocurable resin is composed of resin monomers and prepolymers, and contains active functional groups. Because of the low activation energy required for the reaction, photopolymerization can occur in...

Problems solved by technology

[0003] Research on the application of photopolymerization in new fields has also attracted more and more attention. The application of photopolymerization in laser rapid prototyping technology is the latest application research of photopolymerization. In laser rapid prototyping photocuring, it is used as photopolymerization The photocurable resin of the molding material is an important part of the three-dimensional light modeling system, but in the prior art, most of the petrochemical products are used as raw materials for production, such as polyurethane, polyester, epoxy compound or polyether, etc., using such substances , which will lead to low degradability of the produced resin, high procurement cost of raw materials, and narrow procurement channels, which is not conducive to the health and environmental protection of production workers. During the oil crisis, it is easy to cause raw material procurement risks in enterprise operations;
