Document Type and Number:
Japanese Patent JPWO2021187258
Kind Code:
A1
Abstract:
Provided are a material for an acoustic matching layer in which, while using tungsten carbide particles having a large specific gravity as a metal filler, it is possible to effectively increase an acoustic impedance of an acoustic matching sheet obtained by suppressing a decrease in acoustic velocity due to the formulation of the tungsten carbide particles, and it is also possible to suppress variations in acoustic characteristics in this acoustic matching sheet; an acoustic matching sheet; an acoustic wave probe; an ultrasound probe; an acoustic wave measurement apparatus; an ultrasound diagnostic apparatus; and a method for manufacturing an acoustic wave probe. The material for an acoustic matching layer contains the following components (A), (B), and (C):(A) an epoxy resin;(B) a curing agent; and(C) surface-treated tungsten carbide particles subjected to a surface treatment with a surface treatment agent including at least one of an aminosilane compound, a mercaptosilane compound, an isocyanatosilane compound, a thiocyanatosilane compound, an aluminum alkoxide compound, a zirconium alkoxide compound, or a titanium alkoxide csompound.
