Description
Technical field
The invention belongs to construction material preparing technical field, be specifically related to a kind of roll-forming slag building waste sheet material.
Background technology
Along with industrialization, the acceleration of urbanization process, building industry is the most fast-developing, with this together be building waste day by day
Increasing, a large amount of building wastes not only occupy soil, and bring severe contamination to human habitat.According to statistics, I
The every annual meeting of state increases building waste more than 4,000 ten thousand tons newly, and the quantity of building waste has accounted for more than the 1/3 of municipal refuse total amount, its
Middle concrete construction rubbish has accounted for again more than the 40% of building waste.This phenomenon has been obtained for the extensive pass of the whole society
Note.Land resource is not only wasted in storing up for a long time of building waste, easily produces potential safety hazard, is unfavorable for the sustainable development of resource
Recycling with resource；And the heap of building waste is released and can be polluted water resource, has influence on air quality, and then
Directly influence the living environment of the mankind.Annual industrial coal produces slag about 2-4 hundred million tons, and utilization rate is low and mainly sharp with low side
With for main, bring huge test to environmental problem, become problem anxious to be resolved.Building waste is through crushing, pulverize, sieving
After processing, it is possible to obtain construction waste powder, its SiO2、Al2O3Content is higher, has the value of regeneration；And slag
Main component is CaCO3、CaSO4、CaCl2Deng, its alkali content is the highest.Therefore, building waste and slag are used in mixed way and meet product
The condition of raw alkali-activated carbonatite Binder Materials reaction.Alkali-activated slag building waste is less in application aspect research, especially at plate at present
Still in blank in the application of material goods.Therefore, alkali-activated slag building waste sheet material the most for building is sought further
Become a reality required.
Patent CN201310699108.X discloses a kind of ground polymers-polymer composite board and preparation method thereof.Including
Resin adhesive liquid 12-18 part；High alkali liquid 59-66 part；Building waste 30-40 part；Flyash 30-40 part；Cement 30-40 part；Glass
Fiber 0.5-1 part；Interface enhancer 3-5 part.Method includes: the 1) pulverizing of building waste flyash and screening；2) polymers-poly-
The mixture of compound composite material: be dissolved in benzyl alcohol by resin, adds ethylenediamine, forms resin adhesive liquid；Prepare high alkali liquid；Dense
Alkali liquor is gradually added into building waste and slag, continuously stirred under be sequentially added into cement, glass fibre, Interface enhancer, resin
Glue, had both obtained ground polymers-polymer composites；3) molding of polymers-polymer composite board: by ground polymers-polymer
Composite pours in mould, then proceeds to mould be dried in drying baker, takes out goods after cooling.This ground polymers-polymer
Composite board uses polymer matrix composites, and toughness is had a surplus, rigidity not enough, there is the defects such as relatively low, the loss of properties on aging of intensity,
The aspects such as landslide terrain surface hardening can only be applied topically to；Exciting agent uses substantial amounts of concentrated base, strong base solution, exists relatively
Big safety in production hidden danger.
