Problems solved by technology

In order to solve the problem of coal gangue storage, it is necessary to expropriate land to build a coal gangue storage site, which consumes a lot of money and invades land resources; in dry seasons, strong winds will generate a lot of dust and pollute the environment; Cross flow may cause mudslides and other disasters in the stacking site of coal gangue that is too high, causing heavy losses to people's lives and property
In recent years, although my country has effectively developed and utilized various coal gangue resources, most of them are made of building materials, with low added value and limited consumption.

Abstract

The invention belongs to the technical field of building materials, and particularly relates to a brownish red gangue encaustic tile and a preparation method thereof. Preparation materials of the gangue encaustic tile comprise gangue sand, a harmless treating agent, a glaze complexing agent and water; the harmless treating agent is composed of calcium chloride, quick lime and land plaster which are mixed; harmless treatment is carried out on the gangue, and the technical problem is solved that a gangue product separates out crystal substances during the long-term use process in a natural environment so as to reduce the service life; the invention provides a new method of gangue resource utilization, the gangue consumption is increased, the production process is clean and environmentally friendly, and the productivity is high; according to the gangue encaustic tile, the development and utilization of the gangue resources are improved, and the additional valve of products can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a brown-red coal gangue glazed tile and a preparation method thereof. Background technique [0002] Over the years, solid coal gangue waste from coal mining has piled up like mountains. In order to solve the problem of coal gangue storage, it is necessary to expropriate land to build a coal gangue storage site, which consumes a lot of money and invades land resources; in dry seasons, strong winds will generate a lot of dust and pollute the environment; Cross flow may also cause disasters such as mudslides and other disasters in the stacking site of coal gangue piled up too high, which will bring great losses to people's lives and property. In recent years, although my country has effectively developed and utilized various coal gangue resources, most of them are used to make building materials, with low added value and limited consumption. With the develop...
