Problems solved by technology

The application realizes the high strength of the ceramic rock slab by setting the composition of the rock slab, bottom glaze and top glaze. The above effect can be achieved only if the three are highly matched. If the blank and glaze fluctuate during production , when the combination of the two is not ideal, it is not easy to achieve the purpose of increasing the strength of the rock slab
[0007] At present, there is no composition for rock slab bodies that is low in cost and can better improve the problem of cold working cracking of rock slabs

Abstract

The invention discloses a composition for a high-strength and high-toughness rock plate blank and application of the composition. The composition comprises feldspar powder, high-alumina clay, calcined talc, pyrophyllite, potassium-sodium feldspar, high-sodium feldspar, ball clay, kaolin, diopside, high-alumina clay, ceramic waste and white carbon black. The white carbon black with the characteristics of serious surface coordination insufficiency, large specific surface area, surface oxygen deficiency and the like is used in the composition for the high-strength and high-toughness rock plate blank, so that the binding force between materials is improved, and the strength, toughness, ductility and tear resistance of the blank material are greatly improved. The rock plate blank body prepared by the method has relatively high breaking strength, relatively high toughness and relatively high stress resistance, and the situation of cutting cracks of the prepared rock plate is greatly reduced.

Description

technical field [0001] The present invention relates to the technical field of ceramic slate production, in particular to a composition for a high-strength and high-toughness slate green body, and also relates to a method for preparing a slate from the green body composition and a slate prepared therefrom. Background technique [0002] With the improvement of people's living standards and the continuous development of science and technology, building decoration and decoration materials are increasingly developing towards new decorative materials that are environmentally friendly, multi-functional, high-strength and light-weight, finished products, and intelligently controlled. The aesthetics are becoming more and more personalized, and the styles are more and more diverse. [0003] As a new type of ceramic product, slate is a new concept evolved on the basis of ceramic thin plate and ceramic large plate. The paving efficiency is high, so it has quickly become popular in the...
