Abstract

The invention discloses a silicon-modified inorganic slurry fireproof heat insulation plate with Class A permeability and a preparation method thereof, and relates to the technical field of building heat insulation plates. The heat insulation plate is mainly prepared from the following raw materials in parts by weight: 5 to 10 parts of low density polystyrene foam heat insulation plate, 50 to 70 parts of common silicate cement, 0.5 to 2 parts of organosilicone water repellent, 2 to 5 parts of cement composite early strength agent, 3 to 6 parts of fly ash, 10 to 20 parts of water, and 5 to 10 parts of vinyl-acetate vinyl copolymerizing emulsion. The heat insulation plate with Class A permeability has the characteristics that the heat-insulation property, fireproof property and the like areexcellent; the compressive strength is high, the heat conduction efficient is low, the hydrophobic effect is good, the curing cycle is shorter, the production efficiency is high, and the fireproof property is high.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation boards, in particular to a silicon-modified inorganic slurry permeability grade A fireproof thermal insulation board and a preparation method thereof. Background technique [0002] Insulation board is a kind of building energy-saving material. Its own thermal insulation performance can effectively reduce the energy consumption of buildings, which is in line with the development direction of national green and energy-saving buildings. At present, the fire protection rating of insulation boards commonly used in the construction field is B1 or lower. Its energy-saving effect is remarkable, but its fire resistance performance is poor. In actual use, there have been many fire incidents, causing heavy losses. Therefore, new buildings are increasingly favoring insulation materials with a fire rating of A. However, common A-grade thermal insulation materials on the market, such as roc...
