Description
Technical field
The present invention relates to a kind of building materials, more particularly, it relates to a kind of fireproof heated board.
Background technology
At present, in Chinese society total energy consumption, building energy consumption accounts for about 28%, and along with the development of national economy, this ratio also has the trend continuing to increase.Have 30% ~ 50% to be lost by building enclosure in building energy consumption, the heat insulating strengthening building enclosure is the effective measure realizing building energy conservation.Roofing is as one of building envelope, and the thermosteresis caused is greater than exterior wall and ground.In city, because building adopts multilayer or high-level structure, roofing relative area is less, and the energy consumption of generation accounts for 8% ~ 10% of building total energy consumption.And in Rural areas, the energy loss proportion caused by roofing is larger, even reach 40%.Therefore, roofing is the significant points of building energy conservation.In roof structure, reasonably thermal insulation layer is set, the heat insulating effect of buildings can be improved, reduce heating, air conditioner energy source loss, improve indoor thermal comfort.In addition, the quality of thermal insulation layer process also directly affects the waterproof effect of roofing.A large amount of engineering practice shows, under equivalent constructions, material and construction level condition, the well-done roofing of heat insulating, the thermal stress that roof structure bears is little, and waterproof layer occurs that hollowing, crack and the roof leakage phenomenon caused therefrom are also lacked.
At present, thermal insulation layer is essentially by arranging warming plate to realize at roof structure.Certainly, except arranging warming plate to realize insulation at roof structure, but warming plate can be applied in simultaneously equally, and warming plate on the market has graphite polystyrene board, phenolic board, very golden plate, composite magnesium silicate aluminium sheet, vacuum heat-insulating plate, polyurathamc, extruded polystyrene board, rock cotton board, foamed glass insulation board etc., the each have their own characteristic of these warming plates, is roughly divided into two kinds:
1, the fire prevention of A level is not reached,
2, reach the fire prevention of A level, but there is lower column defects:
1) water tolerance, erosion resistances etc. are not strong,
2) toughness and ultimate compression strength inadequate.
Summary of the invention
For the deficiency that prior art exists, the object of the present invention is to provide a kind of fireproof heated board.This fireproof heated board not only has excellent fire prevention and heat-insulating property, also has excellent toughness and ultimate compression strength, also has good waterproof anti-corrosion performance simultaneously.
For achieving the above object, the invention provides following technical scheme:
A kind of fireproof heated board, the raw material that it is main ingredient by following parts by weight is prepared from:
High-alumina cement 100-200 part

Fire retardant 20-40 part
Granular polystyrene 10-25 part
Water 10-30 part
Described sizing agent is by the 1:2-4:1-2 preparation in mass ratio of urethane, polyacrylic ester, styrene-butadiene rubber(SBR);
Described fire retardant is by the 1:4-6:2-3 preparation in mass ratio of HBCD, diphenyl phosphate, trimeric cyanamide.
By adopt technique scheme, improve sizing agent and fire retardant, and and fireproof heated board other materials play synergy, jointly improve this fireproof heated board fire resistance, toughness, compressive property and waterproof anti-corrosion performance.
It is the first additive prepared by 1:20-40 that described fireproof heated board also to comprise by polycarboxylate water-reducer and whipping agent according to volume ratio, and the quality summation of described mineral mountain flour and granular polystyrene and the volume ratio of the first additive are 1kg/L-2kg/L.
The one in pentane, methylene dichloride selected by described whipping agent.
The preparation method of described polycarboxylate water-reducer:
(1) by vinylformic acid, methylpropene sodium sulfonate, ammonium persulphate, the polymerization degree be 23 polyoxyethylene groups allyl ester polymeric monomer be made into deionized water the aqueous solution that massfraction is 20% respectively;
(2) in the three-necked flask that agitator, reflux condensing tube and thermometer are housed, vinylformic acid, methylpropene sodium sulfonate, the polymerization degree be 23 polyoxyethylene groups allyl group polymeric monomer be that 4:1.2:1 drips in batches according to mol ratio, the polymerization degree adding dropping is again the initiator ammonium persulfate of the 2%-4% of the polyoxyethylene groups allyl group polymeric monomer quality of 23, after dropwising at 70-80 DEG C insulation reaction 3-6h, after reaction terminates, with NaOH aqueous solution adjust ph to 7 ~ 9 that massfraction is 15-30%, obtain yellow or reddish-brown polycarboxylate water-reducer.
By technique scheme, reduce water consumption and the unit weight of this fireproof heated board, reduce thermal conductivity, strengthen heat-insulating property.
Described fireproof heated board also comprises hardening accelerator and flyash is Second addition 10-20 part prepared by 1:2-3 according to weight ratio.
The preparation method of described hardening accelerator:
1. by weight, the Al of CaO, 10-40% of 20-50% is taken
2o
3, 5-10% SiO
2, 10-50% BaSO
4medicine is as raw material;
2. by CaO, Al
