Abstract

The invention discloses a decomposable environment-friendly ceramic composite material and a preparation method thereof. The decomposable environment-friendly ceramic composite material is composed of the following raw materials: kaolin, acetyl tributyl citrate, plant fiber, sand ginger black clay, talc, white clay , Polylactide, sand, potassium feldspar. In the preparation process of the decomposable and environment-friendly ceramic composite material of the present invention, ceramic raw materials such as kaolin, sand ginger black clay, white clay, and sand are mixed and fired, and ground and dispersed evenly. Butyl ester and polylactide are compression-molded, and the ceramic composite material made has good toughness, low brittleness, good tolerance, and is decomposable.

Description

technical field [0001] The invention relates to the technical field of ceramic composite materials, in particular to a decomposable environment-friendly ceramic composite material and a preparation method thereof. Background technique [0002] Ceramic matrix composite material is a kind of composite material which is composed of ceramic as matrix and various fibers. The ceramic substrate may be high temperature structural ceramics such as silicon nitride and silicon carbide. These advanced ceramics have excellent properties such as high temperature resistance, high strength and stiffness, relatively light weight, and corrosion resistance. However, the fatal weakness of these ceramics is their brittleness. When they are in a state of stress, cracks or even fractures will result in material failure. The use of high-strength, high-elasticity fibers and matrix composites is an effective method to improve the toughness and reliability of ceramics. Fibers can prevent the expansi...
