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 elasticity light-cured temporary resin composition described in any one of the above technical solu...

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.

Abstract

The invention provides an ultrahigh-elasticity photocured temporary resin composition as well as a preparation method and application thereof. The composition contains the following components in parts by weight: 15-45 parts of an acrylate compound, 1-10 parts of an acrylate cross-linking agent, 10-70 parts of an acrylate active diluent, 2-10 parts of a thickening agent, 0.5-4 parts of a photoinitiator and 0.01-0.1 part of a stabilizer. By virtue of the cooperation of specific aids such as the acrylate cross-linking agent and the acrylate active diluent, the finally prepared photocured temporary resin is moderate in flexural strength and high in elasticity modulus, can be used for partially replacing a rubber dam and is easy and convenient to use. In the use process, a to-be-covered part is coated with the composition, the composition can be cured within several seconds so as to finish the cover isolation, and after the operation of an oral cavity is finished, the composition can be directly torn down by a hand, so that the composition is favored by dentists, and the industrial blank is filled up.

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...
