Embodiment

[0156] The present invention will be described in more detail based on examples, but the explanation of the present invention should not be limited to the following examples. In addition, "room temperature" means 25 degreeC. In addition, the compounding quantity of a component shows the compounding quantity of a component itself. That is, when a raw material contains a solvent, it is the quantity after removing a solvent.

preparation example

[0157] [Preparation example] Preparation of adhesive

[0158] Mix the epoxy resin, polyamine compound and alcohol compound shown in the following table according to the compounding ratio shown in the following table, and use "degassing Rentaro ARV-310 (trade name, manufactured by THINKY company)" at room temperature, reduced The mixture was defoamed for 5 minutes while stirring at 2000 rpm while the pressure was reduced to 1.0 Pa, to obtain an adhesive. In addition, in each of the test examples described below, an adhesive just prepared was used.

Abstract

Provided are: an endoscope adhesive agent that contains an epoxy resin containing at least one of a bisphenol A epoxy resin, a bisphenol F epoxy resin, and a phenol-novolac epoxy resin, a polyamine compound, and an alcohol compound; and a cured product thereof. Also provided are: an endoscope to which the cured product is fixed; and a method for producing the same.

Description

technical field [0001] The present invention relates to an adhesive for an endoscope, a cured product thereof, an endoscope, and a manufacturing method thereof. Background technique [0002] Endoscopes for observing the inside of body cavities of the human body are used repeatedly. Therefore, the flexible tube constituting the insertion portion of the endoscope is cleaned and sterilized with chemicals every time it is used. In particular, when inserting into a site with a high possibility of infection, such as a bronchi, cleanliness at a sterilization level superior to disinfection is required. Therefore, high durability is required for the endoscope, which can withstand repeated sterilization treatment by hydrogen peroxide plasma or the like. [0003] The insertion part of the endoscope is inserted into the body cavity through the oral cavity, the nasal cavity, and the like. In order to reduce the patient's foreign body sensation and pain during insertion, it is expected...
