Problems solved by technology

[0002] With the continuous improvement and improvement of the properties of dental composite resins, its strength, hardness and wear resistance have met the requirements, but studies have shown that the long-term existence of dental composite resin curing shrinkage stress can lead to a decrease in resin strength and microcracks , and even material fracture, so it is of great significance to develop resins with wear resistance, low shrinkage and commercial application

Abstract

The invention provides an adamantane based resin composite and a preparation method thereof. The adamantane based resin composite comprises an adamantane based resin monomer and a curing agent glycidyl methacrylate, wherein the adamantane based resin monomer is an adamantane derivative with a tannin skeleton, and provided with phthalic anhydride and derivative groups thereof. A prepared resin has the advantages of stable structure, high temperature resistance, low shrinkage rate, good biological activity, and the like; and in the manufacturing method of the resin, reaction conditions are mild, and reactions are implemented simply and easily.

Description

technical field [0001] The invention relates to an adamantyl resin composition and a manufacturing method thereof. More specifically, the present invention relates to dental restorative resins. Background technique [0002] With the continuous improvement and improvement of the properties of dental composite resins, its strength, hardness and wear resistance have met the requirements, but studies have shown that the long-term existence of dental composite resin curing shrinkage stress can lead to a decrease in resin strength and microcracks , and even material fracture, so it is of great significance to develop a resin with wear resistance, low shrinkage and commercial application. [0003] Adamantane is a cyclic tetrahedral hydrocarbon containing 10 carbon atoms and 16 hydrogen atoms. Its basic structure is chair-shaped cyclohexane, which is a highly symmetrical and very stable compound. Adamantane has (1) very stable to light; (2) good lubricity; (3) extremely lipophilic...
