Abstract

The invention provides a photocuring retention material and application thereof. The photocuring retention material is prepared from the following raw material components in percentage by mass: 2 to 30 percent of diluted monomer, 10 to 60 percent of polyfunctional group monomer, 10 to 80 percent of large-particle filler, 0.5 to 20 percent of microparticle filler, 0.1 to 15 percent of silane coupling agent, 0.01 to 5 percent of photoinitiator and 0.0001 to 0.2 percent of polymerization inhibitor, the photocuring retention material provided by the invention is a solvent-free, high-curing-speed, boiling-water-boiling-resistant and easy-to-peel material, a low-viscosity and low-volatility diluted monomer is used as a main component, and through compounding of a high-viscosity and high-glass-transition-temperature polyfunctional group monomer, the cohesion is improved, the peeling residue of retention glue is reduced, and the photocuring retention material has the advantages of simple preparation process and low cost. The coating can be quickly cured and formed after being irradiated by an ultraviolet lamp for about 10 seconds, the curing and shaping are quick, and the manufacturing efficiency is improved.

Description

technical field [0001] The invention belongs to the field of adhesive materials, and relates to a photocuring fixing material and its application. Background technique [0002] Removable dentures include removable partial dentures and complete dentures, which use the remaining natural teeth, mucosa and bone tissue under the base as support, rely on the retainers of the denture and the base for retention, and use artificial teeth to restore the shape of the missing teeth And function, using the base material to restore the shape of the defective alveolar ridge, jawbone and the surrounding soft tissue, a prosthetic that patients can remove and wear by themselves. In the production of removable dentures, firstly, the teeth must be manually arranged on the wax base to prepare a wax denture model, and then the wax denture model needs to be embedded in gypsum, boiled to lose wax, die-cast base resin, and hot-pressed. Finally, removable dentures are prepared. In this process, whe...
