[0172]

[0173] The resin composition for an acoustic matching layer of the present invention can be prepared, for example, by using a kneader, a pressurized kneader, an internal mixer (continuous kneader), a twin-roll kneading device, or the like to prepare the components constituting the resin composition for an acoustic matching layer. It is obtained by kneading. Thus, metal particles (C) dispersed in epoxy resin (A) and polyamine compound (B1), preferably dispersed in epoxy resin (A), polyamine compound (B1) and polyamine compound (B2) can be obtained. A resin composition for an acoustic matching layer formed in

[0174] In addition, when making a material set for an acoustic matching layer containing a main ingredient composed of a resin composition containing an epoxy resin (A) and a metal particle (C), and a curing agent containing a polyamine compound (B1) , the main ingredient can be obtained by kneading epoxy resin (A) and metal particles (C). The curing agent pr...

Abstract

Provided is a resin composition for an acoustic matching layer and containing an epoxy resin (A), a specific polyamine compound (B), and metal particles (C), wherein the epoxy resin (A) includes at least one type of epoxy resin from among bisphenol A epoxy resins, bisphenol F epoxy resins, and phenol novolac epoxy resins. Additionally provided are a cured product using said composition, an acoustic matching sheet, an acoustic wave probe, an acoustic wave measurement device, a production method for an acoustic wave probe, and a materials set for an acoustic matching layer.

Description

technical field [0001] The present invention relates to a resin composition for an acoustic matching layer, a cured product, an acoustic matching sheet, an acoustic wave probe, an acoustic wave measuring device, a method for manufacturing an acoustic wave probe, and a material set for an acoustic matching layer. Background technique [0002] The acoustic wave measurement device uses an acoustic wave probe that irradiates an object to be inspected such as a living body with an acoustic wave, receives the reflected wave (echo), and outputs a signal. Reflected waves received by the acoustic probe are converted into electrical signals and displayed as images. Therefore, by using the acoustic wave probe, it is possible to visualize and observe the inside of the subject. [0003] As the acoustic wave, an ultrasonic wave, a photoacoustic wave, or the like is appropriately selected according to the object to be examined and also according to the measurement conditions. [0004] Fo...
