Abstract
A kind of oral medical material gypsum hardener and preparation method thereof, belongs to oral medical technical field of material.The gypsum hardener is made of isopropanol, ethyl alcohol and methyl cyclopentane according to the volume ratio of 18 ~ 20 ︰, 4~6 ︰ 1~2.The preparation method is as follows: being stirred by ultrasonic 10 minutes after isopropanol, ethyl alcohol, methyl cyclopentane are mixed according to the volume ratio of 18 ~ 20 ︰, 4~6 ︰ 1~2 at 25 DEG C, and mix well to get gypsum hardener is arrived.The beneficial effects of the present invention are: (1) enhances the mechanical performance of gypsum, and then increase the effect of its oral restoration；(2) this method is a kind of preparation method of medical material gypsum hardener material low in cost and excellent in mechanical performance.
Description
Technical field
The invention belongs to oral medical technical field of material, and in particular to a kind of oral medical material gypsum hardener
And preparation method thereof.
Background technique
In oral restoration work, repairing and treating effect depends not only on the design of doctor, and by various reparations
The influence of material.Therefore, the quality of material directly affects the effect of Dental Erosion, such as the common material gypsum of gear division, oral cavity
It repairs and be unable to do without plaster cast, and the hardness of plaster cast is directly related to the effect of oral restoration, gypsum table thus occurs
This dental prosthetic material of face curing agent, the purpose of addition be exactly in order to enhance the mechanical performance of gypsum such as surface compression strength,
Surface hardness etc..Gypsum surface curing agent has the classes such as epoxy resin, acrylic resin, cyanoacrylate resin, organic siliconresin
Type.In recent years, China has developed many kinds of epoxy curing agents, such as aliphatic amine curing agent, boracic curing agent, virtue
Amine curing agent, organic siliconresin curing agent are then studied considerably less both at home and abroad.Currently, the domestic dental prosthetic material stone used
The cream surface hardener overwhelming majority is from foreign import, these products are easy to use, excellent effect, but its price compares
Valuableness, our unsuitable developing countries use.Farther out, therefore the product using effect of China's production is differed with imported product
Develop the task of top priority that the novel product for being suitble to most of domestic manufacturers to use is our scientific workers.
Summary of the invention
The purpose of the present invention is provide a kind of oral medical material gypsum to solve the above-mentioned problems in the prior art
Curing agent and preparation method thereof.
In order to solve the above technical problems, the technical solution adopted by the present invention is that:
A kind of oral medical material gypsum hardener, the oral medical material gypsum hardener by isopropanol, ethyl alcohol and
Methyl cyclopentane composition, the volume ratio of the isopropanol, ethyl alcohol and methyl cyclopentane are (18 ~ 20): (4~6): (1~2).
A kind of preparation method of oral medical material gypsum hardener, the method comprises the following steps:
Ethyl alcohol and methyl cyclopentane are mixed with isopropanol, and using ultrasonic agitation 10 minutes between 24 ~ 26 DEG C, sufficiently
It mixes to get gypsum hardener is arrived.
The beneficial effect of the present invention compared with the existing technology is:
(1) mechanical performance of gypsum is enhanced, and then increases the effect of its oral restoration；
(2) this method is a kind of preparation side of medical material gypsum hardener material low in cost and excellent in mechanical performance
Method.
Specific embodiment
Below with reference to embodiment, further description of the technical solution of the present invention, and however, it is not limited to this, all right
Technical solution of the present invention is modified or replaced equivalently, and without departing from the spirit and scope of the technical solution of the present invention, should all be contained
Lid is within the protection scope of the present invention.
Specific embodiment 1: a kind of oral medical material gypsum hardener, the oral medical material gypsum hardener
It is made of isopropanol, ethyl alcohol and methyl cyclopentane, the volume ratio of the isopropanol, ethyl alcohol and methyl cyclopentane is (18 ~ 20):
(4~6): (1~2).
Specific embodiment 2: a kind of oral medical material gypsum hardener described in specific embodiment one, described different
The volume ratio of propyl alcohol, ethyl alcohol and methyl cyclopentane is 18:4:1.
Specific embodiment 3: a kind of oral medical material gypsum hardener described in specific embodiment one, described different
