Description
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 development of science and technology, people have higher requirement to constructional materials.Existing heat-preserving heat-insulating wall material is all undesirable on various performances; Existing light wall material mainly contains: the gel materials for wall; Adopt cementitious material, haydite, sand, water reducing agent and water etc. to be made; The sheet material surface density is big, relies on haydite to improve the heat preservation and insulation of sheet material, poor effect merely; Cement perlite glass fiber light wall material, its defective are the perlite water imbibitions, indoor seasoning, and suction back wall skin comes off; Glass fiber light wall material, its defective are that alkali resistance is poor, are Powdered after the corrosion, and pulling force and tension force reduce; Cement mortar light wall material, its defective are that the materials for wall volume is heavy, are prone to moisture absorption expansion drying and shrink the generation crack; In addition in order to reach heat insulation effect, also have and adopt the outer materials for wall that pastes self-insulation system, though can improve the heat insulating effect fire endurance and combustibility does not reach requirement.
In producing light wall material technology for building, bubble mainly adopts following two kinds of system foam method formulas in the concrete at present.The one, machinery system bubble, the gas that adopts the animal/vegetable protein blowing agent to convert water and certain pressure by a certain percentage makes foam through the gauze wire cloth of certain compactness together, adds the forced mixer stirring again and in concrete, forms pore; Yet this method system bubble receives the blowing agent performance impact bigger, and the size of air pressure and the compaction rate of gauze wire cloth also can influence foaming effect, and the bubble survival rate is lower in stirring the back concrete simultaneously, and many is harmful pores of connection.The 2nd, chemical blowing gets into 50～70 ℃ of steaming kiln maintenances after adopting raw material such as aluminium powder or hydrogen peroxide solution and flyash, gypsum to mix to be stirred into mould, generation hydrogen or oxygen in this process and in concrete, form pore; Yet this method requires more sternly should not control to curing temperature, exists harmful pore of more connection to have a strong impact on concrete compressive strength and durability in the concrete simultaneously.
Summary of the invention
Goal of the invention: existing light heat insulation material heat preservation and insulation is not good in order to solve, the defective of refractoriness difference, the invention provides a kind of light heat-insulation wall material and preparation method thereof.
Technical scheme: in order solving the problems of the technologies described above, to the invention provides a kind of light heat-insulation wall material, to comprise the hole that body and body interior are intensive.
A kind of preferred as technical scheme of the present invention, the described hole diameter is 1-2mm, evenly distributes, to obtain the durability of better heat insulating ability, refractoriness and materials for wall.
The present invention also provides a kind of preparation method of light heat-insulation wall material, may further comprise the steps:
(1) with the even concrete that gets of raw material stirring, said raw material comprises cement, silica flour, haydite, granular polystyrene, water reducing agent and water;
(2) the preparation light wall material mould in place bar frame, the concrete that stirs evenly is distributed in the mould, through the indent that vibrates after atmospheric steam curing again through the HTHP maintenance, promptly gets said light heat-insulation wall material after the form removal.
In order to obtain better heat insulating ability and refractoriness, optimized process conditions:
In the step (1), mixing time is 150-240 second; Can make stirring more even, more economical;
The diameter of said granular polystyrene is 1-2mm, and the empty size of size control materials for wall through granular polystyrene makes size more even;
Said water reducing agent is preferably one or more mixture of polycarboxylate water-reducer, naphthalene water reducer, aliphatic water reducing agent and amino water reducing agent;
Said raw material also comprises blowing agent, and said blowing agent is preferably one or more mixture of vegetable protein blowing agent, rosin 206 blowing agents, azodiisobutyronitrile and neopelex;
In the step (2), said atmospheric steam curing temperature is 60-90 ℃, and the time is 3.5-6.0h; Said high-pressure steaming and cultivating temperature is controlled at 150-180 ℃, and pressure is 0.85-1.1Mpa, and the time is 5-8h;
Said raw material is to add 0.1-0.5m in the common prescription
3Granular polystyrene, every cubic meter of concrete raw material use amount is preferably: cement 200-500Kg, 0.1-1000Kg sand, silica flour 0.1-200Kg, haydite 0.1-0.8m
3, granular polystyrene 0.1-0.5m
3, water reducing agent 0.1-10Kg, water 0.1-200Kg.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: a kind of light heat-insulation wall material thermal and insulating performance provided by the invention is good, refractoriness is good, light weight, easy to use, cost is low.
The granular polystyrene of employing 1-2mm replaces traditional sand as fine aggregate, can obviously alleviate the surface density of lightweight body of wall, makes the materials for wall quality lighter, convenient transportation and use.And materials for wall is behind the HTHP steam press maintenance, and granular polystyrene has not existed itself in the sheet material concrete structure, thereby can not influence its fire endurance because of the existence of granular polystyrene, has improved the fire resistance of sheet material greatly; And the space that granular polystyrene is left over after disappearing because of cement slurry is wrapped to form a large amount of disconnected pores, and in this pore the coefficient of thermal conductivity of secluding air well below haydite concrete, thereby improve its thermal and insulating performance greatly; And granular polystyrene is wrapped evenly distribution in concrete by cement slurry after stirring, and after pressing steaming, all becomes self-existent pore, and each pore does not link to each other mutually, and concrete durability is not had influence.
Simultaneously, this preparation method's technology is simple, and the granular polystyrene source of employing is abundant, and cheap, quality receives external factor affecting little, is suitable for suitability for industrialized production.0
