Abstract

The invention discloses a decorative insulation board which comprises a decorative surface layer, an insulation layer and a back board, the insulation layer is a polyurethane foam board, and the decorative surface layer and the back board are both calcium silicate boards. The decorative insulation board is prepared from the following raw materials in parts by weight: 40-45 parts of power plant flue ash, 8-10 parts of cement, 8-10 parts of calcium sulfate, 8-10 parts of desulfurized gypsum, 10-12 parts of reinforced fibers, 3-5 parts of ethylene-vinyl acetate copolymer emulsion, 3-5 parts of calcium silicate whiskers, 8-10 parts of waste porcelain powder and 3-5 parts of butadiene styrene rubber particles. By adjusting the raw materials of the decorative surface layer and the back board, the adopted raw materials are more environment-friendly and energy-saving, and the prepared facing layer and back board are high in strength and long in service life.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation materials, in particular to a decorative thermal insulation board and a preparation process thereof. Background technique [0002] Building energy consumption mainly includes losses in household appliances, air conditioning, hot water supply, lighting, cooking, heating, etc. Among them, heating and air conditioning consume a relatively high proportion of energy consumption, which will cause energy waste. Based on the current requirements of the construction industry for green and energy-saving buildings, higher requirements are also put forward for the interior and exterior wall decoration and insulation materials of buildings. Building insulation materials generally use polyurethane foam templates, inorganic mortar insulation boards, etc., and specific requirements such as light weight and easy installation , heat preservation, flame retardant, long service life, etc., while d...
