Description
Technical field
The present invention relates to a kind of preparation method of damping environmental protection building block, belongs to building material technical field.
Background technology
At present, junked tire brings huge environmental issue as Industry hazardous solid waste to society, its institute
The black pollution of formation be deteriorate natural environment, destroy vegetation growth, affect human health, to jeopardize ball ecological environment most harmful
One of rubbish.The common method for processing solid waste is as filled, burning, and junked tire is not all applied to.Junked tire belongs to
In macromolecular material, their macromole is decomposed does not affect the degree of plant growing in soil to need year of centuries
Month.If burning, its smog for being discharged and carbon monoxide, can severe contamination air.Cumulative junked tire is long-term
Air storage, not only occupies a large amount of soils, and through exposing to the sun and rain, easily grows mosquito, spreads disease, and is also easy in addition
Initiation fire.Therefore, waste and used rubber tyre recoverying and utilizing method is sought, it has also become society's problem in the urgent need to address.
China's stalk resource owning amount ranks first in the world, and annual production is about 6.5 hundred million tons.And the profit of the current stalk resource of China
It is but very low with rate, only 33%, remaining most of stalk resource is incinerated or is merely served as fuel as agriculture and forestry organic waste material,
A large amount of wastes of resource allocation are caused, while the environment for human survival that pollution goes from bad to worse.As an environmental protective measure,
Straw receives people and widely payes attention to for application of the building block as materials for wall under construction.
At present, the materials for wall of China substantially belongs to fragile material, and the significant variability of its strength of materials and fragility are broken
Bad pattern so as to which anti-seismic performance is difficult prediction.It is substantial amounts of in 8.0 grades of Wenchuan in 2008 and the 7.1 grades of violent earthquakes of cajaput in 2010
Filling wall, partition wall destruction are serious, cause function to be lost, and produce heavy economic lossess or even casualties, and this Earthquake damages is said
The unfavorable factors such as rigidity effect, the effect of restraint that bright filling wall is produced cause structural damage, and due to its fragile material, and
Earthquake energy is unable to, causes seismic energy further to amplify in the structure, structural deterioration is even more serious.
The content of the invention
The present invention proposes a kind of preparation method of damping environmental protection building block, produces with energy-dissipating and shock-absorbing effect, and is incubated
Heat-insulated environment-friendly type damping environmental protection building block so as to which solid waste is rationally utilized, and while makes body of wall play in earthquake
Its damping effect, mitigates earthquake and building itself is destroyed.What the technical solution adopted in the present invention was specifically realized in：
The invention provides a kind of preparation method of damping environmental protection building block, comprises the following steps that：
A) by discarded rubber tyre, rubber, clean after arranging, room temperature is crushed to the mesh of 30 mesh -80, makes rubber
Powder, soaks 24 hours in 10%NaOH solution, dries, and is cleaned with clear water, then dries, and acts on 1-2 under microwave environment afterwards
Hour, in case taking；
B) by silane and ethanol in mass ratio 1：5-1：15 configurations, under airtight condition, full and uniform dispersion forms silane wine
Smart solution；
C) by the silane alcoholic solution with the rubber powder with silane：The ratio of rubber powder=0.5%-2% is melted
Close, and stir on homogenizer, at least more than 15min makes silane alcoholic solution fully merge with rubber powder, form rubber
Fusions, it is open afterwards to spread placement at least more than 30min out, make ethanol fully volatilize, in case taking；
D) on pulverizer by crushed stalk to stalk fibre, and the stalk fibre is placed in 10%NaOH solution
After immersion at least 24 hours, take out, dry, cleaned with clear water, then dry；
E) the rubber fusions, the stalk fibre are added to into flyash, Calx, Gypsum Fibrosum, cement, foaming agent, water
Mixed liquor in stir, be then transferred to molding in fixing mould, at least place 24 hours after, still kettle is delivered in the demoulding
In, at least steam pressure 6 hours in 180 DEG C of saturation distilled water, discharging.
Preferably, the silane in step b is the coupling agent of silane 550.
Preferably, the stalk fibre length in step d is 2-3cm.
Preferably, it is shaped to vibration moulding in step e.
Preferably, it is shaped to compaction moulding in step e.
