Abstract

The invention discloses a fiber-reinforced thermal insulation board and a preparation method thereof, and relates to the technical field of thermal insulation boards.The fiber-reinforced thermal insulation board is prepared from the following raw materials in parts by weight: 65 to 75 parts of modified magnesium oxysulfate cement slurry, 35 to 45 parts of desulfuration gypsum, 30 to 31 parts of modified expanded perlite, 29 to 30 parts of modified diatomite, 24 to 26 parts of fly ash, 24 to 26 parts of waste glass powder, 15 to 16 parts of auxiliary agents and 75 to 85 parts of water. The fiber-reinforced thermal insulation board has a better compressive property and is not easy to crack, the preparation method is simple and the cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of thermal insulation boards, in particular to a fiber-reinforced thermal insulation board and a preparation method thereof. Background technique [0002] As a big country in construction, my country's building energy consumption accounts for about 27% of the country's total energy consumption, but the level of building energy conservation is far lower than that of developed countries in the world, and the unit building energy consumption is 3-5 times that of developed countries with similar climates. The development of new building energy-saving and environmentally friendly materials has important practical significance for improving resource utilization, improving the environment, saving energy and reducing emissions. Building insulation boards are mainly used in building walls, roofs, windows, floors and other parts to play a role in heat insulation and are important indicators of building energy conserva...
