Embodiment 1

[0023] A novel resin tooth is composed of 1-10 parts by weight of surface-treated short glass fiber, 50-60 parts by weight of acrylic polymer, 20-40 parts by weight of acrylic monomer, and 0.001-0.1 part by weight of pigment.

[0024] Wherein, the short glass fiber can be formed by one or more combinations of A glass fiber, E glass fiber, C glass fiber and S glass fiber. The acrylic polymer can be composed of one or more combinations of polymethyl methacrylate, polyethyl methacrylate, and polydimethacrylate diisocyanate. The acrylic monomer can be formed by one or more combinations of methyl methacrylate, ethyl methacrylate, butyl methacrylate and diisocyanate dimethacrylate. The pigment is composed of iron oxide red and titanium yellow.

Embodiment 2

[0026] Based on the principle of Embodiment 1 above, this embodiment discloses a specific implementation of a new type of resin tooth.

[0027] A novel resin tooth is composed of 8 parts by weight of surface-treated short glass fiber, 50 parts by weight of acrylic acid polymer, 30 parts by weight of acrylic monomer and 0.001 part by weight of pigment.

[0028] The short glass fiber is made of S glass fiber, the acrylic polymer is made of polymethyl methacrylate, and the acrylic monomer is made of methyl methacrylate; the pigment is made of iron oxide red and titanium yellow.

Embodiment 3

[0030] Based on the novel resin tooth of the above-mentioned embodiment, this embodiment discloses its specific manufacturing method, and the method includes the following steps:

[0031] A. Surface treatment of short glass fibers:

[0032] At room temperature, short glass fibers were added to a mixture of triethylene glycol dimethacrylate, 1,7,7-trimethyl-bicyclo[2.2.1]heptane-2,3-dione, N, Fully stir in the mixture that N-dimethylaminobenzoic acid ethyl ester forms for 1-3 hour;

[0033] After filtering, spread the short glass fiber on a glass plate to form a thin layer with a thickness less than or equal to 3mm, and irradiate it with 300-400nm visible light for 5 minutes;

[0034] B. Mix 1-10 parts by weight of surface-treated short glass fibers, 20-40 parts by weight of acrylic monomers, and 0.001-0.1 parts by weight of pigments;

[0035] C. At a temperature of 5°C-25°C, 50-60 parts by weight of an acrylic polymer is mixed into the mixture prepared in step B and mixed un...

Abstract

The invention discloses a novel resin tooth and a production method thereof. The resin tooth is prepared from the following components in parts by weight: 1 to 10 parts of surface-treated short glassfiber, 50 to 60 parts of an acrylic polymer, 20 to 40 parts of an acrylic monomer and 0.001 to 0.1 part of a pigment. Compared with an existing resin tooth made of a polymethylmethacrylate material, the resin tooth has the advantages that the anti-fatigue strength, creep-resisting performance, anti-impact performance and wear-resisting performance are remarkably improved and a patient can chew hard foods including nuts, bones and the like.

Description

technical field [0001] The invention relates to the field of oxygen inhalers, in particular to a novel resin tooth and a manufacturing method thereof. Background technique [0002] Resin dental products currently on the market are mainly formed by injection molding or hot pressing of polymethyl methacrylate or its modified copolymers. Polymethyl methacrylate or PMMA, commonly known as plexiglass, is by far the most excellent variety of synthetic transparent materials. However, when it is used as the raw material of resin teeth, the patient will continue to wear the resin teeth when chewing; and because it is a polymer material, the patient cannot chew hard foods such as nuts and bones after installing the resin teeth, which affects the use of patients experience. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a novel resin tooth and a manufacturing method thereof. [0004] The present invention...
