Problems solved by technology

Although above-mentioned two kinds of prior art limit the synthetic method of polyurethane acrylate and the molecular weight of polyol, the thermosetting system that both mainly adopt is epoxy curing system, and epoxy resin system is brittle, and cost is high and and There may be compatibility problems in the acrylic resin system; the added isobornyl ester has a relatively large odor and poor environmental protection; and the resin compositions provided by the two do not add inorganic component fillers, and the wear resistance and strength are difficult. Meet actual needs

Abstract

The invention provides a photo-thermal curing resin composition and a preparation method and application thereof. The resin composition comprises a combination of a prepolymer, a monomer, a photoinitiator, a thermal initiator, fumed silica and glass powder in specific parts, the photoinitiator in specific parts is added to be matched with the thermal initiator, the completion rate of a curing reaction is increased, the resin composition is more sufficiently cured, and the monomer residual rate after curing is lower. Specific parts of fumed silica and barium-containing glass powder are also added as fillers, so that the hardness, strength and wear resistance of the resin composition are effectively enhanced, and a product obtained by performing 3D printing on the finally obtained resin composition completely meets the requirements of serving as a temporary crown bridge.

Description

technical field [0001] The invention belongs to the technical field of resin materials, and in particular relates to a photothermally cured resin composition and a preparation method and application thereof. Background technique [0002] Temporary crowns and bridges are temporary crowns or bridges that are used in the field of oral implantology and restoration before the patient wears the final crown. The production of traditional temporary crowns and bridges mainly uses tray powder and tray water mixed by hand, and the production methods are generally divided into intraoral or extraoral methods. Since the residual methacrylic resin has a great irritating and acrid odor, the treatment experience brought by the patient is very bad. At present, some processing factories use cutting technology to make PMMA temporary crowns and bridges. PMMA has realized digital processing, and the efficiency has increased. However, there are problems of low utilization rate of incoming materia...
