Abstract

The invention discloses a fiber-reinforced rock plate and a preparation method thereof, and relates to the technical field of building materials, the rock plate comprises the following raw materials by weight: 30-45 parts of kaolin, 10-30 parts of bauxite, 15-25 parts of feldspar, 0-5 parts of talc, 15-25 parts of quartz, and 1-15 parts of ceramic fiber. According to the fiber-reinforced rock plate, the aluminum silicate fibers or the aluminum oxide fibers and the rock plate powder are fully mixed to prepare the rock plate, so that the bending strength and the toughness of the rock plate are remarkably improved. Compared with a rock plate without aluminum silicate fibers or aluminum oxide fibers, the bending strength of the rock plate is increased by 60% or above.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a fiber-reinforced slate and a preparation method thereof. Background technique [0002] With the continuous development of science and technology and the continuous improvement of human living standards, architectural decoration is developing in the direction of new decorative materials that are high-strength, lightweight, thin, environmentally friendly, multi-functional, standardized in installation, and intelligent in control. [0003] For the new rock slab, due to its large area (3200mm*1600mm) and thin thickness (tends to 3mm), there are still many technical problems in the process of processing and use, for example: if the mechanical strength is not high, the problems in the process of processing and use are prominent . With the continuous improvement of safety requirements for high-rise curtain walls, high-end home decoration, high-end clubs and national public...
