Abstract

The invention provide a light-weight high-strength foamed ceramic board material, which is characterized by being prepared from the following components, by weight part: 50-60 parts of coal ash, 10-20 parts of bentonite, 10-20 parts of dolomite, 6-12 parts of potassium and sodium feldspar, 8-15 parts of magnesite slag, 5-10 parts of waste glass, 1-2 parts of an anionic surfactant, 0.5-1.5 parts of a silicon resin polyether emulsion, 0.1-0.5 part of a foaming agent, 0.1-0.5 part of a dispersant, and 200-250 parts of water. Cost of raw materials is reduced, and resources are saved. The light-weight high-strength foamed ceramic board material has characteristics of environmental protection, fire prevention, sound absorption, heat insulation, moisture resistance, seepage resistance, freezing resistance, and flame retardation, and conforms to a modern construction energy-saving standard, so that the material can be used as a wall insulation material, a sound-insulation noise-reduction material, or a heat-insulation thermal-insulation material in other fields.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a lightweight high-strength foamed ceramic plate and a preparation method thereof. Background technique [0002] Wall insulation is the key to building energy conservation. External wall insulation has become the first choice in the construction industry because of its relatively convenient construction, especially suitable for cold regions such as the north. Building exterior wall insulation material is an important factor affecting building energy saving. At present, organic thermal insulation materials have almost occupied the domestic building thermal insulation material market. Machine insulation materials mainly include expanded polystyrene board (EPS), extruded polystyrene board (XPS), spray polyurethane (SPU), polystyrene particles, etc. Its advantages are mainly light weight, high density, good thermal insulation, but there are also many disadvan...
