Problems solved by technology

[0005] At present, there are many polishing methods. The polishing products used include tungsten steel grinding head, ceramic bond grinding head and electroplated diamond bur. , it is easy to cause cracks on the surface of the denture that are not easy to be observed by the naked eye, and reduce the service life of the denture; and the gloss of the polishing does not meet the requirements for use, and it needs to be glazed and sintered again or polished with other abrasive consumables and abrasive paste. This method of polishing Takes a long time and increases patient discomfort

Embodiment 1～6

[0024] A kind of dental polishing rubber grinding head, described rubber grinding head is prepared by following components:

[0025]

[0026]

Embodiment 7

[0028] The present embodiment provides the preparation method of the rubber grinding head for dental polishing described in Embodiment 1, comprising the following steps:

[0029] (1) Use an open mill to mix the silicone rubber and micropowder evenly, then add zinc stearate and magnesium stearate, then add hardening agent, and finally add DBPMH, in order to ensure uniform mixing, continue mixing after adding the materials 20min.

[0030] (2) Put the mixed raw materials into the mould, and use a hot press at 100°C to press for molding.

[0031] (3) To ensure complete vulcanization, take the grinding head out of the mold and place it in an oven for secondary vulcanization at 150°C.

Embodiment 8

[0033] The present embodiment provides the preparation method of the dental polishing rubber grinding head described in embodiment 2, comprising the following steps:

[0034] (1) Mix the isoprene rubber and micropowder evenly with an open mill, and then add sulfur. In order to ensure uniform mixing, continue mixing for 20 minutes after adding the materials.

[0035] (2) Put the mixed raw materials into the mould, and use a hot press at 70°C to press and form.

[0036] (3) To ensure complete vulcanization, take the grinding head out of the mold and place it in an oven for secondary vulcanization at 130°C.

Abstract

The invention relates to a rubber grinding head for polishing. The rubber grinding head is manufactured, by weight, 60-80 parts of rubber, 20-40 parts of micro-powder, 3-4 parts of a vulcanizing agent, 0-10 parts of a hardening agent and 0-20 parts of padding. Rubber is adopted as the material of the polishing grinding head and has elasticity, the soft rubber collides with a hard object in the polishing process, the brightness and smoothness of a polished surface can be improved, meanwhile the strength of the rubber is high, toughness is good, and the service life of the grinding head is ensured. In addition, the cooling padding is added to the grinding head, the temperature in the polishing process is effectively lowered, the surface of a ground material is effectively protected, cracks are not liable to be generated, and the service life of the ground material is prolonged.

Description

technical field [0001] The invention belongs to the technical field of dental consumables, and in particular relates to a rubber grinding head for dental polishing, a preparation method and application thereof. Background technique [0002] my country has a large population, and the problem of aging is becoming increasingly apparent. With the increase of age, oral diseases will appear more or less. For most of the elderly and a small number of young people, a series of problems such as swollen gums, tooth decay, loose teeth and tooth loss will bring serious problems to daily life. A lot of inconvenience, to solve these problems, everyone will go to major hospitals and clinics to repair teeth. According to the reactions of doctors in major stomatological hospitals, the number of patients who have their teeth trimmed is increasing, and there is basically no time for re-glazing and sintering. As people pay more and more attention to oral hygiene, oral cleaning and oral beauty...
