Abstract

The invention discloses a shell-like mother-of-pearl layer material with a layered structure and a preparation method thereof. The method comprises the following steps: uniformly mixing the carbonized cementitious material with water at a water-solid ratio of 0.3 to 1.2 to obtain a suspension of the carbonized cementitious material; treating the suspension of the carbonized cementitious material with a freezing casting process to obtain a layered The carbonized cementitious material solidification of structure; freeze-dry the carbonized cementitious material solidification with layered structure, obtain the carbonized cementitious material with layered structure; Carry out carbonization hardening of the carbonized cementitious material with layered structure, A shell-like mother-of-pearl layer material with a layered structure is obtained. In the present invention, the imitation shell mother-of-pearl layer material with a layered structure is obtained by combining the freezing casting technology with the carbonization technology. The obtained material has high fracture toughness and durability, and at the same time, the preparation process has low energy consumption and can solidify carbon dioxide. Function, and no waste generated, in line with the concept of environmental friendliness.

Description

technical field [0001] The invention relates to the field of bionic technology, in particular to a shell imitation mother-of-pearl layer material with a layered structure and a preparation method thereof. Background technique [0002] Shell mother-of-pearl is a natural structural composite material with a macroscopic to microscopic lamellar structure. Although most of it is composed of brittle aragonite calcium carbonate, its unique layered structure makes the overall toughness a separate document. More than 3,000 times that of stone flakes. On the micron scale, the mother-of-pearl layer of the shell presents a three-dimensional "brick-mud" structure, and the densely stacked 95vol% aragonite calcium carbonate sheets are used as "bricks", and 5vol% biopolymers are used as "mud" to connect the aragonite sheets , The layered hierarchical structure composed of alternating soft and hard phases endows it with excellent mechanical properties, realizing the combination of strength,...
