preparation example Construction

[0021] A preparation method of aluminum silicate fiber, comprising the following steps:

[0022] The slag clinker and mineral clinker are melted and fiberized to obtain aluminum silicate fiber;

[0023] The mineral is selected from one or more of coal gangue, burnt gem and kaolinite.

[0024] In the present invention, water slag clinker and mineral clinker are first melted. In the present invention, the source of the water slag clinker is not limited, and the water slag clinker known to those skilled in the art will suffice. Water slag is the process of rapidly cooling blast furnace slag in hot melt state in water. There are mainly two methods: water quenching in slag pool or water quenching in front of furnace. The present invention does not limit the components and sources of the water slag clinker, and conventional industrial wastes can be used. Preferably, the water slag clinker consists of the following components:

[0025]

[0026] The mineral clinker is prepared ...

Abstract

The invention provides a preparation method of aluminium silicate fibers. The preparation method comprises the steps of melting water granulated slag clinkers and mineral clinkers and carrying out fiber forming treatment on the water granulated slag clinkers and mineral clinkers to obtain the aluminium silicate fibers, wherein minerals are selected from one or more of coal gangue, flint clay and kaolinite rocks. In the preparation method of aluminium silicate fibers, provided by the invention, the aluminium silicate fibers are prepared by using the ironmaking wastes, namely the water granulated slag clinkers and the coal gangue clinkers, as raw materials, so that the aluminium silicate fibers not only can be used at 1000 DEG C but also can meet the requirement of heat insulation in most fields such as power, petrochemistry, metallurgy and the like and replace basalt and slag, use industrial wastes as the raw materials, are lower in cost and reduce environmental pollution caused by the wastes.

Description

technical field [0001] The invention belongs to the field of thermal insulation materials, and in particular relates to an aluminum silicate fiber and a preparation method thereof. Background technique [0002] There are many kinds of thermal insulation materials, and their application range is also very wide. Classification by material composition includes: organic heat insulation materials, inorganic heat insulation materials, and metal heat insulation materials. Classification by material shape includes: loose thermal insulation materials, plate-shaped thermal insulation materials and overall thermal insulation materials. [0003] In the prior art, the inorganic thermal insulation materials include glass wool, rock wool and the like. Among them, the use temperature of glass wool is below 250°C, and the use temperature of rock wool is below 450°C, both of which are relatively low. And it mainly uses natural basalt, slag and other materials for production, but the above-...
