Abstract

The invention provides a piezoelectric ceramic composite material and a preparation method thereof. The preparation method comprises the following steps: firstly, mixing and stirring Portland cement, aluminate cement, octadecanamide, beeswax, bisphenol A epoxy resin, bisphenol F epoxy resin, erythritol, 651 low-molecular polyamide, m-phenylenediamine, polyvinyl acetal, calcium propionate, sodium carboxymethyl cellulose, absolute ethyl alcohol and water, vacuumizing, and eliminating gas; then putting a piezoelectric ceramic sheet into a mold, pouring the mixture into the mold and vibrating, and continuing pouring to make the mold full of the mixture; and putting the mold into a vacuum system, vacuumizing, eliminating gas, then putting the mold into a standard curing room, curing, demolding, and continuing curing; and finally cutting until the piezoelectric ceramic sheet is exposed at two surfaces of the sample. The piezoelectric ceramic composite material has relatively low acoustic impedance rate and relatively high compressive strength, besides, noise can be effectively shielded, the sensor receiving performance is good, and in addition, a cement hydration reaction can be effectively detected.

Description

technical field [0001] The invention relates to the field of materials, in particular to a piezoelectric ceramic composite material and a preparation method thereof. Background technique [0002] In today's society, buildings stand like jungles between cities and towns. In recent decades, they have sprung up like mushrooms after rain. They have become a symbol of modernization and an indispensable and important part of modernization. components, which have greatly promoted the progress of human society. As an indispensable part of building materials, cement has important research value and significance for its various performance indicators such as hydration time, rheology and durability. At the same time, as time goes by, its various performances will decline and the damage will accumulate, which will easily cause major accidents. Therefore, effective detection and early warning of these buildings are of great significance for preventing and reducing accidents. Piezoelec...
