Foamed ceramic insulation board and preparation method thereof

Abstract

The invention discloses a foamed ceramic insulation board and a preparation method thereof. The foamed ceramic insulation board is prepared from the following raw materials by weight: 35-65 parts of waste glass ceramic powder, 20-30 parts of phosphate tailing, 15-35 parts of kaolin, 5-15 parts of sodium potassium feldspar, 8-16 parts of fly ash, 4-10 parts of calcined talc, 2-10 parts of bentonite, 4-12 parts of silicon powder, 1-6 parts of talcum powder, 3-12 parts of calcium carbonate, 2-10 parts of magnesium carbonate, 5-15 parts of water glass, 1-5 parts of a foaming agent, 0.3-0.8 part of an anionic surfactant, and 0.5-1.5 part of a dispersant. The foamed ceramic insulation board provided by the invention has low thermal conductivity, fire prevention, high temperature resistance, aging resistance, low water absorption, weather resistance and other superior performance, and the preparation method is simple and is easy for implementation, therefore the foamed ceramic insulation board can be widely applied in the fields of construction, electricity and environmental protection, etc.

Description

technical field [0001] The invention relates to an energy-saving and thermal insulation material for walls, in particular to a foamed ceramic thermal insulation board and a preparation method thereof. Background technique [0002] With the development of my country's national economy, new wall materials in the construction industry are facing the challenge of replacement. In the "National Economic and Social Development 'Twelfth Five-Year' Plan and 2015 Vision Outline", building energy conservation and waste utilization have been listed important industry for the country. In recent years, my country's residential buildings have entered a period of large-scale construction, and wall materials account for 70% of building materials, and their demand has greatly increased. [0003] Faced with the use of such large-scale wall energy-saving materials, the development of new clean energy and energy conservation are necessary steps to achieve sustainable economic development. At pre...

Problems solved by technology

Organic materials include polystyrene foam plastics, polyurethane foam plastics, etc., which have disadvantages such as low ignition point, easy poisoning, and many building diseases, and the earth endangers the safety of people's lives and property

[0004] At present, foamed ceramic insulation board is a new type of lightweight insulation material, because it has high porosity, low thermal conductivity, light weight, high hardness, thermal shock resistance, high temperature resistance, corrosion resistance and good mechanical strength. performance, so it is widely used, but when it is used as the exterior wall of a building, there are still problems such as poor thermal insulation effect and unsatisfactory waterproof and fireproof performance.
