Embodiment 1
[0030] A high wear-resistant composite resin for a denture base, comprising the following raw materials in parts by weight: 50 parts of n-butyl methacrylate, 30 parts of bifunctional bisphenol-A dimethacrylate, 5 parts of β-hydroxypropyl methacrylate Parts, 2.5 parts of a-hydroxy-cyclohexyl phenyl ketone, 1.5 parts of stabilizer, 1.5 parts of plasticizer, 35 parts of inorganic filler.
[0031] In this example, the surface of the inorganic filler is modified by an isolation modifier. The isolation modifier is a series of modifiers with double-terminal single epoxy functional groups, specifically ethylene glycol diglycidyl ethers with different molecular weights and molecular chain lengths. And its polymer, the isolation modifier is attached to the surface of the inorganic filler after being bonded by the terminal functional group, and the plurality of inorganic filler particles are isolated from each other by the isolation modifier on the surface.

Embodiment 3
[0054] A high wear-resistant composite resin for a denture base, comprising the following raw materials in parts by weight: 50 parts of n-butyl methacrylate, 30 parts of bifunctional bisphenol-A dimethacrylate, 5 parts of β-hydroxypropyl methacrylate Parts, 2.5 parts of a-hydroxy-cyclohexyl phenyl ketone, 1.5 parts of stabilizer, 1.5 parts of plasticizer, 37.5 parts of inorganic filler.
[0055] In this example, the surface of the inorganic filler is modified by an isolation modifier. The isolation modifier is a series of modifiers with double-terminal single epoxy functional groups, specifically ethylene glycol diglycidyl ethers with different molecular weights and molecular chain lengths. And its polymer, the isolation modifier is attached to the surface of the inorganic filler after being bonded by the terminal functional group, and the plurality of inorganic filler particles are isolated from each other by the isolation modifier on the surface.
