Description

A kind of preparation method of light heat-insulation wall material
Technical field
The present invention relates to a kind of preparation method of materials for wall, particularly a kind of preparation method of light heat-insulation wall material.
Background technology
Along with the development of science and technology, people have higher requirement to construction material.Existing heat-preserving heat-insulating wall material is all undesirable in various performance, existing light wall material mainly contains: gel materials for wall, Binder Materials, haydite, sand, water reducer and water etc. is adopted to be made, sheet material surface density is large, simple dependence haydite improves the heat preservation and insulation of sheet material, poor effect; Cement perlite glass fiber light wall material, its defect is perlite water imbibition, indoor seasoning, and water suction back wall skin comes off; Glass fiber light wall material, its defect is that alkali resistance is poor, and in Powdered after corrosion, pulling force and tension force reduce; Cement mortar light wall material, its defect is materials for wall volume weight, and easy moisture absorption expansion drying is shunk and produced crack; In addition in order to reach heat insulation effect, also having and adopting the outer materials for wall pasting self-insulation system, although heat insulating effect fire endurance can be improved and combustibility does not reach requirement.
At present in production light wall material technology for building, in concrete, bubble mainly adopts following two kinds of bubble modes processed.One is machine bubble, adopts animal/vegetable protein blowing agent to be watered by a certain percentage and obtain foam by the steel wire of certain packing together with the gas of certain pressure, then adds forced mixer stirring and in concrete, form pore; But the party's legal system bubble is comparatively large by blowing agent performance impact, the size of air pressure and the compaction rate of steel wire also can affect foaming effect, and after stirring, in concrete, bubble survival rate is lower simultaneously, many harmful pores for being communicated with.Two is chemical blowings, enters 50 ~ 70 DEG C of steaming kiln maintenances after adopting aluminium powder or hydrogen peroxide and the raw material such as flyash, gypsum mix and blend to enter mould, generates hydrogen or oxygen in the process and in concrete, forms pore; But the method requires more sternly should not control to curing temperature, there is more multiply connected harmful pore in concrete simultaneously and have a strong impact on concrete compression strength and durability.
Summary of the invention
Goal of the invention: in order to solve the defect that existing light heat insulation material heat preservation and insulation is not good, fire resistance is poor, the invention provides a kind of light heat-insulation wall material and preparation method thereof.
Technical scheme: in order to solve the problems of the technologies described above, the invention provides a kind of light heat-insulation wall material, comprises body and the intensive hole of body interior.
One as technical solution of the present invention is preferred, and described hole diameter is 1-2mm, is uniformly distributed, to obtain the durability of better heat insulating ability, fire resistance and materials for wall.
Present invention also offers a kind of preparation method of light heat-insulation wall material, comprise the following steps:
(1) stir raw material to obtain concrete, and described raw material comprises cement, silica flour, haydite, granular polystyrene, water reducer and water;
(2) in the mould preparing light wall material, place bar frame, the concrete be stirred evenly is distributed in mould, through atmospheric steam curing after the indent that vibrates, again through HTHP maintenance after form removal, obtain described light heat-insulation wall material.
In order to obtain better heat insulating ability and fire resistance, optimize process conditions:
In step (1), mixing time is 150-240 second; Can stirring be made evenly, more economical;
The diameter of described granular polystyrene is 1-2mm, is controlled the size in materials for wall cavity by the size of granular polystyrene, make size evenly;
Described water reducer is preferably the mixture of one or more of polycarboxylate water-reducer, naphthalene water reducer, aliphatic water reducing agent and amino water reducer;
Described raw material also comprises blowing agent, and described blowing agent is preferably the mixture of one or more of vegetable protein blowing agent, rosin 206 blowing agent, azodiisobutyronitrile and neopelex;
In step (2), described atmospheric steam curing temperature is 60-90 DEG C, and the time is 3.5-6.0h; Described high-pressure steaming and cultivating temperature controls at 150-180 DEG C, and pressure is 0.85-1.1Mpa, and the time is 5-8h;
Described raw material is the granular polystyrene adding 0.1-0.5m3 in common prescription, and every cubic meter of concrete raw material use amount is preferably: cement 200-500Kg, 0.1-1000Kg sand, silica flour 0.1-200Kg, haydite 0.1-0.8m3, granular polystyrene 0.1-0.5m3, water reducer 0.1-10Kg, water 0.1-200Kg.
Beneficial effect: compared with prior art, its remarkable advantage is in the present invention: a kind of light heat-insulation wall material thermal and insulating performance provided by the invention is good, fire resistance is good, quality is light, easy to use, cost is low.
Adopt the granular polystyrene of 1-2mm to replace traditional sand as fine aggregate, obviously can alleviate the surface density of Light Wall, make materials for wall quality lighter, conveniently transport and use.And materials for wall is after HTHP steam press maintenance, in sheet material xoncrete structure, granular polystyrene does not exist itself, thus can not affect its fire endurance because of the existence of granular polystyrene, substantially increases the fire resistance of sheet material; And granular polystyrene disappear after the space left over because cement slurry is wrapped to form a large amount of disconnected pore, and in this pore, the thermal conductivity factor of isolated air, well below haydite concrete, thus improves its thermal and insulating performance greatly; And granular polystyrene to be wrapped by cement slurry and is uniformly distributed in concrete after stirring, after pressure is steamed, all become self-existent pore, each pore is not connected mutually, on concrete durability without impact.
Meanwhile, this preparation method's technique is simple, and the granular polystyrene abundance of employing, cheap, quality affects little by external factor, is suitable for suitability for industrialized production.
