The invention discloses a kind of fireproof heated board, it is prepared from by following parts by weight for the raw material of major constituent：100 200 parts of alumina cement, 10 20 parts of mineral mountain flour, 10 20 parts of adhesive, 20 40 parts of fire retardant, 10 25 parts of granular polystyrene, 10 30 parts of water, adhesive is by polyurethane, polyacrylate, butadiene-styrene rubber in mass ratio 1：2‑4:12 prepare, and fire retardant is by HBCD, diphenyl phosphate, melamine in mass ratio 1:4‑6：23 prepare.Beneficial effects of the present invention：The fireproof heated board has excellent fire prevention and heat-insulating property, also with excellent toughness and compression strength, while also having good waterproof anti-corrosion performance.
Description
Technical field
The present invention relates to a kind of building materials, more specifically, it relates to a kind of fireproof heated board.
Background technology
At present, building energy consumption accounts for 28% or so in Chinese society total energy consumption, and with the development of national economy, this
Ratio also has the increased trend of continuation.There is 30%~50% to be lost by building enclosure in building energy consumption, strengthen building enclosure
Insulation be the effective measures for realizing building energy conservation.Roofing is used as one of building envelope, caused heat waste
Lose and be more than exterior wall and ground.In city, because building uses multilayer or high-level structure, roofing relative area is smaller, the energy of generation
Consumption accounts for building the 8%~10% of total energy consumption.And in rural area, the energy loss proportion caused by roofing is bigger, very
To reaching 40%.Therefore, roofing is the significant points of building energy conservation.It is rational in roof structure that heat-insulation layer, Ke Yiti are set
The heat insulating effect of high constructure, reduction heating, air conditioner energy source loss, improves indoor thermal comfort.In addition, heat-insulation layer is handled
Quality also directly affect the waterproof effect of roofing.A large amount of engineering practices show, in equivalent constructions, material and construction level condition
Under, the well-done roofing of insulation, the temperature stress that roof structure is born is small, and hollowing, crack and thus occurs in waterproof layer
Caused by roof leakage phenomenon it is also few.
At present, heat-insulation layer sets warming plate to realize essentially by roof structure.Certainly, except being set in roof structure
Warming plate realizes insulation, but warming plate equally can be using at the same time, and warming plate on the market has graphite polystyrene board, phenol
Aldehyde plate, true golden plate, composite magnesium silicate aluminium sheet, vacuum heat-insulating plate, polyurathamc, extruded polystyrene board, rock cotton board, foam glass are protected
Warm plate etc., each have their own characteristic of these warming plates, is roughly divided into two kinds：
1st, A grades of fire prevention are not reached,
2nd, reached A grades of fire prevention, but in the presence of column defects：
1) water resistance, corrosion resistance etc. is not strong,
2) toughness and compression strength are inadequate.
The content of the invention
In view of the deficienciess of the prior art, it is an object of the invention to provide a kind of fireproof heated board.The fireproof heat insulating
Plate not only has excellent fire prevention and heat-insulating property, also with excellent toughness and compression strength, while also preventing with good
Water Corrosion Protection.
To achieve the above object, the invention provides following technical scheme：
A kind of fireproof heated board, it is prepared from by following parts by weight for the raw material of key component：
100-200 parts of alumina cement
10-20 parts of mineral mountain flour
10-20 parts of adhesive
20-40 parts of fire retardant
10-25 parts of granular polystyrene
10-30 parts of water
The adhesive is by polyurethane, polyacrylate, butadiene-styrene rubber in mass ratio 1：2-4：It is prepared by 1-2；
The fire retardant is by HBCD, diphenyl phosphate, melamine in mass ratio 1：4-6：It is prepared by 2-3.
By using above-mentioned technical proposal, adhesive and fire retardant are improved, and send out with the other materials of fireproof heated board
Synergy is waved, fire protecting performance, toughness, compressive property and the waterproof anti-corrosion performance of the fireproof heated board are improved jointly.
It is 1 according to volume ratio that the fireproof heated board, which is also included by polycarboxylate water-reducer and foaming agent,:20-40 prepare the
One additive, the quality summation of the mineral mountain flour and granular polystyrene is 1kg/L-2kg/L with the volume ratio of the first additive.
One kind that the foaming agent is selected in pentane, dichloromethane.
The preparation method of the polycarboxylate water-reducer：
(1) by acrylic acid, methylpropene sodium sulfonate, ammonium persulfate, the polyoxyethylene groups allyl ester polymeric monomer that the degree of polymerization is 23
The aqueous solution that mass fraction is 20% is made into deionized water respectively；
(2) in the three-neck flask equipped with agitator, reflux condensing tube and thermometer, acrylic acid, methylpropene sodium sulfonate,
The polyoxyethylene groups pi-allyl polymeric monomer that the degree of polymerization is 23 is 4 according to mol ratio:1.2:1 is added dropwise in batches, adds the poly- of dropwise addition
In 70-80 after the 2%-4% of the right polyoxyethylene groups pi-allyl polymeric monomer quality for being 23 initiator ammonium persulfate, completion of dropping
Insulation reaction 3-6h at DEG C, after reaction terminates, the NaOH aqueous solution for being 15-30% with mass fraction adjusts pH value to 7~9, obtains
Yellow or rufous polycarboxylate water-reducer.
By above-mentioned technical proposal, reduce the water consumption and unit weight of the fireproof heated board, reduce thermal conductivity factor, enhancing insulation
Performance.
It is 1 that the fireproof heated board, which also includes early strength agent and flyash according to weight ratio,：Second addition prepared by 2-3
10-20 parts.
The preparation method of the early strength agent：
1. by weight, 20-50% CaO, 10-40% Al are weighed2O3, 5-10% SiO2, 10-50% BaSO4Medicine
It is used as raw material；
2. by CaO, Al2O3、SiO2、BaSO4Mixture through in planetary mills fully homogenizing, chamber type electric resistance furnace 1000-1300
DEG C calcining and powder grinding etc. technical process, prepare early strength agent.
By using above-mentioned technical proposal, early strength agent adds the early strength of the fireproof heated board, and flyash is added
The bulk strength of the fireproof heated board.
A kind of preparation technology of fireproof heated board, it is characterised in that：Comprise the following steps：
Step 1：Granular polystyrene and mineral mountain flour are foamed respectively；
Step 2：By 10-25 parts of granular polystyrene, 10-20 parts of mineral mountain flour, 100-200 parts of alumina cement, adhesive 10-
20 parts, 20-40 parts of fire retardant, add 100-120 parts of water, stir 5-10min；
Step 3：Well mixed mixture is inverted in grinding tool, control forming temperature increases pressure at 50-75 DEG C or so
