The foaming heat insulation board can overcome the defects that the high heat insulation and low volume weight as well as the high strength and high tenacity of the existing foaming heat insulation board are difficult to simultaneously take into consideration, and has excellent overall performances in fire protection, heat insulation, strength and waterproof aspects and the like.
Description
Technical field
The present invention relates to energy-saving building materials technical field, be specifically related to a kind of A level fire-proof foamed heated board, and the preparation method of this A level fire-proof foamed heated board.
Background technology
Foaming insulation board refers to the warming plate using foam cement technology to manufacture, also known as foamed concrete warming plate, inorganic fireproof heat insulating plate, with Portland cement, flyash, whipping agent, admixture etc. for material, through the lightweight balloon shape thermal insulation material that the techniques such as compound, stirring, foaming, cutting are made.Because it has good resistivity against fire, the preferably advantage such as heat insulation property and intensity, light weight and long service life, replace the Conventional insulation such as EPS (polystyrene foam), XPS (extruded polystyrene foam), PU (polyurethane foam), stone(mine)cotton plate, glass fiber blanket and polyphenylene granule heat-insulating slip at present gradually and be applied to wall thermal insulating fire-blocking belt and be used as exterior-wall heat insulation.
Although foaming insulation board has in the market possessed A level fire resistance, but in the over-all propertieies such as heat-insulating property, intensity, water-absorbent, entirety has much room for improvement: due to the reason of composition and engineering, the bubble structure of foaming insulation board is undesirable, rate of closed hole is low, cause that water-absorbent is high, frost resistance is poor, be not suitable for using in cold district; It is high that low rate of closed hole makes convection of air conduct heat, and thermal conductivity is generally at 0.065-0.08W/ (m.k); The ultimate compression strength of plate is poor, in transport and construction process, easily occurs phenomenon of rupture, affects result of use.
Summary of the invention
Technical problem to be solved by this invention is the deficiency for above prior art problem, a kind of A level fire-proof foamed heated board is provided, this foaming insulation board overcomes the defect being difficult between the insulation of existing foamed heat insulating plate hight, low unit weight and high strength, high tenacity simultaneously take into account, the high comprehensive performance in fire prevention, insulation, intensity, waterproof etc.
The technical solution adopted in the present invention is:
A kind of A level fire-proof foamed heated board, this warming plate is prepared from primarily of each raw material of following parts by weight: cement 100-140 part, silicon dioxide powder 15-25 part, polypropylene fiber 0.5-1 part, colloid (a kind of component in oil) 1-3 part, whipping agent 8-12 part, suds-stabilizing agent 6-10 part, water reducer 6-12 part.
As preferably, described A level fire-proof foamed heated board is prepared from primarily of each raw material of following parts by weight: cement 105 parts, silicon dioxide powder 20 parts, polypropylene fiber 1 part, colloid 2 parts, whipping agent 10 parts, suds-stabilizing agent 8 parts, water reducer 8 parts.
Particularly, described cement is silicate cement.
Particularly, described whipping agent is hydrogen peroxide.
Particularly, described suds-stabilizing agent is the mixing of one or more in the special suds-stabilizing agent of gas concrete, dimethyl dodecyl amine oxide, alkylol amide.
Particularly, described water reducer is the mixing of one or more in lignin sulfonate naphthalene water reducer, melamine based water reducer, sulfamate based water reducer, aliphatics based water reducer, poly carboxylic acid series water reducer.
The preparation method of above-mentioned A level fire-proof foamed heated board, comprises the following steps:
(1), after taking each raw material of formulation content, the raw material except whipping agent is added filler bin;
(2) one-level stirs: the adjustment rotating speed according to starting material and formula controls to stir 3 minutes under 400-800rpm;
(3) secondary stirs: the adjustment rotating speed according to starting material and formula controls to stir 1 minute under 800-1200rpm;
(4) add the foaming stirring that whipping agent carries out 7-8 second, temperature of reaction controls at 35-40 DEG C, forms slurry;
(5) slurry is built into the automatic movement system of film case, carries out building foaming, and in mould, maintenance 12 hours, obtains work in-process after the automatic dismoulding system demoulding;
(6) work in-process are at Indoor Natural maintenance 12-24 hour (according to the height of temperature adjustment curing time), and then shaping, the packaging of surface trimming, obtains A level fire-proof foamed heated board of the present invention.
On formula, the present invention does not use the existing meeting generally used to fall low intensive flyash, and adopts silicon dioxide powder, while reduction unit weight, replacing partial cement, gains in strength; The conbined usage of silicon dioxide powder and polypropylene fiber contributes to the overall tensile strength of improving product, makes not easy to crack; The interpolation of colloid then contributes to increasing product flexibility, later strength and water resistance; The conbined usage of whipping agent, suds-stabilizing agent, and and other components between the good synergy that formed make bubble structure in cement insulation board plate of the present invention even, rate of closed hole is high, contributes to the lifting of whole synthesis performance.
In preparation technology, the present invention is by the optimization of processing parameter, and make bubble structure in the plate that obtains even, rate of closed hole is high, thus the overall thermal conductivity of product is low, and water-intake rate is low, and ultimate compression strength is good.
Generally speaking, A level fire-proof foamed heated board of the present invention integrate light weight, high-strength, waterproof, insulation, not so, stable performance, over-all properties is better than the heat preservation plate material of other type and foaming insulation board of the same type, is the high-performance exterior wall heat insulating material for external of alternative inorganic heat preservation slurry and organic heat-insulating plate.
