preparation example Construction

[0046] The present invention provides a method for preparing the ultra-high elastic light-cured temporary resin composition described in any one of the above technical solutions, comprising:

[0047] It is obtained by mixing an acrylate compound, an acrylate crosslinking agent, an acrylate reactive diluent, a thickener, a photoinitiator and a stabilizer.

[0048] The present invention has clearly described the specific components and proportions of the above-mentioned acrylate compound, acrylate crosslinking agent, acrylate reactive diluent, thickener, photoinitiator and stabilizer, and will not repeat them here.

[0049]The mixing in the present invention is preferably carried out in a mixing tank; the mixing temperature can be at room temperature; it is 20-35° C.; the mixing time is preferably 3-8 hours.

[0050] The present invention provides the application of the ultra-high elastic photocuring temporary resin composition described in any one of the above technical solutio...

Embodiment 1

[0058] The following components were stirred together to form a paste (mass %):

[0059]

[0060] Mix the above-mentioned components through a mixing tank at room temperature for 3 to 8 hours.

[0061] Apply the paste of the present invention to the parts that need to be covered, and it can be cured for 3 seconds by light to complete the covering and isolation. After the oral operation is completed, it can be directly torn off by hand.

[0062] Test results: flexural strength 70±5MPa, modulus 1.0±0.2GPa.

Embodiment 2

Abstract

The invention provides a super-elastic light-curing temporary resin composition, comprising: 15-45 parts by weight of acrylate compound; 1-10 parts by weight of acrylate crosslinking agent; 10-70 parts by weight of acrylate reactive diluent; 2-10 parts by weight of thickener; 0.5-4 parts by weight of photoinitiator; 0.01-0.1 parts by weight of stabilizer. In the present invention, through the combination of the above-mentioned acrylate compound, acrylate cross-linking agent and acrylate reactive diluent equal to specific additives, the light-cured temporary resin finally prepared has moderate flexural strength and high elastic modulus, and can partially replace the rubber dam , easy to use. When in use, you only need to apply the composition of the present invention on the parts to be covered, and it can be cured for a few seconds to complete the covering and isolation. After the oral operation is completed, you can directly tear it off with your hands. It has been welcomed by dentists and filled the gap in the industry. .

Description

technical field [0001] The invention relates to the field of material technology, in particular to an ultra-high elasticity light-cured temporary resin composition, a preparation method and application thereof. Background technique [0002] When dentists perform oral operations on patients, they often use rubber dams for isolation to prevent dental drugs from irritating the patient's gums. However, the covering range (the whole oral cavity) is too large when using a rubber dam, and the operation is cumbersome and expensive. Therefore, there is an urgent demand for elastic materials that can partially play the role of a rubber dam to achieve partial covering and isolation. Contents of the invention [0003] In view of this, the technical problem to be solved by the present invention is to provide a super-elastic light-cured temporary resin composition. The composition provided by the present invention has moderate flexural strength and high elastic modulus, can partially re...
