Problems solved by technology

[0003] The usual method of fireproofing steel structures is to coat fireproof coatings, but the surface strength of fireproof coatings is low, and the adhesion to joint materials is not good, and joint leakage is prone to occur; at the same time, if the insulation measures for steel structure beams and columns are not in place , it is very easy to form a cold bridge, so a lightweight inorganic thin plate that takes into account both heat preservation and fire prevention is needed

The fireproof thermal insulation sheet comprises 40-55 parts of an active reaction material, 2-6 parts ofa gas forming time regulator, 45-60 parts of sand, 1-5 parts of ultrafine aggregate, 0.3-1 part of a gas forming agent and 0.5-5 parts of a modifier, wherein the gas-forming time regulator is preparedby grinding one of triethanolamine, diethanol amine, pentaerythritol, glycerol and xylitol and building gypsum according to a mass ratio of (1-5): 50; the modifier is cyanamide modified epoxy resin;the gas generating agent is metal aluminum powder, octadecenoic acid and triterpenoid saponin, the particle size of the metal aluminum powder is 10-60 [mu] m for continuous grading, and the ratio of D50 greater than or equal to 10 [mu] m and less than 30 [mu] m to D50 greater than or equal to 30 [mu] m and less than or equal to 60 [mu] m is (1-3): (1-2). The fireproof thermal insulation sheet is good in quality, the heat conductivity coefficient is not larger than 0.10 W/m.K, and the cutting loss rate is not larger than 5% when the thickness is 50-75 mm.

Description

technical field [0001] The invention relates to the field of inorganic materials, more specifically, to a fire-proof and heat-preserving sheet and a preparation method thereof. Background technique [0002] With the development of circular economy and the improvement of requirements for building energy conservation, steel structure buildings have developed rapidly. Auxiliary materials matching steel structures have also become research hotspots, among which the fire protection and heat preservation of steel structures is one of the hotspots. [0003] The usual method of fireproofing steel structures is to coat fireproof coatings, but the surface strength of fireproof coatings is low, and the adhesion to joint materials is not good, and joint leakage is prone to occur; at the same time, if the insulation measures for steel structure beams and columns are not in place , it is very easy to form a cold bridge, so a lightweight inorganic thin plate that takes into account both h...
