Foam cement fireproof heated board for building
Technical field
The present invention relates to a kind of architectural warming plate that is used for, particularly relate to a kind of architectural foam cement fireproof heated board that is used for.
Background technology
At present, in the energy consumption of China, building energy consumption occupies very high proportion; The highlyest can reach 40%, it is topmost to be exactly the consumption of coal, because the burning of coal process produces noxious pollutants such as sulfurous gas, flue dust, lime-ash; Therefore, exploitation is fit to the high-efficiency insulated lagging material of China's national situation, promotes the use of energy saving building; To practicing thrift heating energy consumption, protection environment, keep the sustainable development of Chinese national economy to have great importance.
Summary of the invention
To the problem that prior art proposes, the present invention provides that a kind of thermal conductivity is low, intensity is high, water-intake rate is low, and the foam cement fireproof heated board for building of environmental protection.
For realizing above-mentioned purpose, the present invention adopts following technical scheme to realize:
Foam cement fireproof heated board for building, according to the mass fraction meter, form by following component:
Further, described foam control agent, its structural formula is:
Described hardening accelerator is selected Quilonum Retard for use;
It is 27.5~35% ydrogen peroxide 50 that described whipping agent is selected concentration for use;
Described foam control agent, it is synthetic as follows: the horse acid anhydride input reaction kettle with 1 mole glycerine and 1~2 mole is heated to 50~100 ℃; Ring-opening reaction is incubated the CaO that adds 0.5~1 mole after 0.5~3 hour and is warming up to 100~140 ℃, is incubated 2 hours; The Triple Pressed Stearic Acid that adds 1~2 mole again is warming up to 160~240 ℃, dehydration postcooling to 120 ℃, discharging; Promptly get required foam control agent, the chemical formula of above-mentioned synthetic foam control agent is following:
In the such scheme, because foam cement fireproof heated board for building adopts above-mentioned synthetic foam control agent, the bubble that makes this warming plate be is even, controlled amount, and the bubble that sends is a closed pore bubble independently one by one.Independently the closed pore bubble can block water get into warming plate inside, thereby has played the effect of insulation.
Its concrete parameter of foam cement fireproof heated board for building that adopts such scheme to obtain is following:
Dry density≤250kg/m
3
Thermal conductivity≤0.06w/m.k
Ultimate compression strength >=0.4Mpa
Anti-intensity >=the 0.13Mpa that blocks
Water-intake rate≤10.0 (V/V)
But the foam cement fireproof heated board for building that is obtained by above-mentioned parameter knowledge capital invention technical scheme has advantages such as thermal conductivity is low, intensity is high, specific absorption is low; Do not contain the reactant that produces hazardous and noxious substances in the recipe ingredient of this warming plate simultaneously, so this warming plate fire prevention and environmental protection.
