Description

Composite material for building
Technical field
The present invention relates to a kind of material of construction, particularly relate to a kind of composite material for building and preparation method thereof.
Background technology
Along with the progress and the constant development of economy of society, energy-conservation and environment protection becomes more and more important, and on the one hand, energy-saving and emission-reduction become world's common target, becomes a state basic policy of China, and the aspect protects vegetation, resources conseravtion to become a big behave of China in addition.Under this background, the traditional building material " Qin brick and Han tile " that has passed on thousands of years is banned use of by country and becomes history.China's real estate as mainstay industry, how to solve the material of construction problem that has a large capacity and a wide range referred agenda, both the central and local governments respectively reach province municipal government and all are provided with " wall is corrected ", be responsible for the leading position of development of new building materials, energy-saving building material specially, and put into effect relevant support policies such as reduction or remission of taxes, also open merchant's collection wall simultaneously and change fund to the room.In recent years, just utilize the building material of industrial waste exploitation to engender, as: thermal power plant's waste material desulfurated plaster, aluminium manufacturer's waste material fluorgypsum, phosphate fertilizer plant's waste material phosphogypsum etc. are widely used in making the partition material of building and the filling mold materials of empty stomach concrete building plate.Yet gypsum belongs to hard brittle material, and tension and folding strength are low, is used for building partition and is easy to generate crackle.In addition, a large amount of straw kind agricultural waste (as: straw, corn stalk, high grain bar etc.) is not fully utilized, as: Chengdu annual burning straw not only influences the flight landing and causes environmental pollution.Therefore, the problem that exists at gypsum class building materials reaches pressing for of " wall changing ", in conjunction with the specific requirement of relevant specification of country and market to building partition, as: fire prevention, sound insulation, heat insulation, energy-conservation, the opposing temperature difference and shrinkage crack etc., research and develop a kind of not only economy but also suitable type material and have great importance.
Summary of the invention
Technical problem to be solved by this invention is, a kind of composite material for building and making method are provided, the over-all properties of this matrix material is better than single-material, can be used for making the building sandwich partition board or make the filling mould and be used for the Steel Concrete composite floor plate, its use properties all is better than adopting single-material, and can adjust different compound prescriptions to satisfy the requirement of multiple complexity according to concrete performance requriements, and making method is simple, the duration is short, cost is low, to remedy the deficiency of existing building material.
Composite material for building technical scheme of the present invention is: it comprises the matrix material that coagulated material and framework material are formed, and being filled in by coagulated material condenses in the gap of framework material forms.Wherein framework material is shaft-like, the stem shape of farm crop or forestry plant, shape or fibrous material on an empty stomach, as straw, cogongrass, high grain bar, corn stalk, Lu Wei bar, grass stalk, bamboo branch, branch, Folium Pini etc.Coagulated material adopts has gypsum or lime material mothproof, anticorrosion, the rapid hardening performance.
Weakness agricultural, forestry waste material poor durability that mothproof, the antiseptic property of coagulated material overcome, and shaft-like, stem shape, shape or fibrous farming on an empty stomach, advantage that forestry waste material tensile strength is high have overcome the fragility of gypsum or lime and have easily split weakness, and the rapid hardening characteristics of gypsum make production efficiency improve greatly.Gypsum material originally is a heat insulating energy saving material (thermal conductivity is 0.34) preferably, and the thermal conductivity of straw kind material only is about 0.1, thereby the material after compound is than gypsum excellent insulating energy-saving material more.
Described coagulated material adopts high-intensity cement or magnesium chloride or other glue class material.
Described coagulated material adopts any two or more coagulated material in aforesaid gypsum, lime, cement or the magnesium chloride to mix.
Described framework material adopts shaft-like, the stem shape of farm crop or forestry plant, any two or more the different framework material in shape or the fibrous material mixes on an empty stomach.
Mix lagging material in the matrix material of coagulated material and framework material, lagging material accounts for coagulated material weight 10~30%.Lagging material is pearlstone, granular polystyrene, haydite etc.
In the matrix material of coagulated material and framework material, mix subsidiary material.Subsidiary material are packing material, enhancing aggregate.
The packing material that mixes in the matrix material of coagulated material and framework material accounts for coagulated material weight 10~30%.Packing material is flyash, volcanic ash, saw foam.
The enhancing aggregate that mixes in the matrix material of coagulated material and framework material accounts for coagulated material weight 10~30%.The enhancing aggregate is high strength aggregates such as slag, scum.
Mix foam material in the matrix material of coagulated material and framework material, foam material accounts for coagulated material weight 5~20%.Foam material is an aluminium powder.
The complex method that the making method of described matrix material, coagulated material are filled in the gap of framework material is once cast-in-place moulding or layered cast-in-situ once shaped, and its step is as follows:
The first, prepare mould according to desired thickness, length, width;
The second, in mould, press a layer positive quadraturing laying framework material;
The 3rd, coagulated material is put into stirrer stir and to make it mix Hou Jiashui to make the pulpous state coagulated material;
The 4th, the pulpous state coagulated material is cast in the mould by on the framework material of layer positive quadraturing laying and vibrated and make in its gap that is filled in framework material;
The 5th, maintenance reaches the demoulding after the intensity;
The 6th, size is as required cut.
For composite thickness is more than the 400mm, and the layering produced with combination repeats second~the 4th process.
In the 3rd process, if also use subsidiary material, foam material or/and lagging material, should be with the coagulated material of needs, subsidiary material, foam material or/and lagging material is put into stirrer stirs and make it mix Hou Jiashui to make the pulpous state coagulated material.
Compare with the single-material that existing building is used, the present invention has made full use of farming, forestry waste material and the gypsum material very big complementarity on performance, it is condensed in make it remedy modification mutually together, thereby obtain the matrix material of excellent property, its manufacture craft is simple, duration is short, cost is low, remedied the defective of single-material on use properties, make it can satisfy the service requirements of construction work, thereby promote various industrial waste gypsum and farming, the comprehensive utilization of forestry waste material on material of construction, energy-saving and emission-reduction are fulfilled, and it is more that " Qin brick and Han tile " found, better substitute products, it is practical that wall is changed.
