Description
Technical field
The invention belongs to building material technical fields, and in particular to a kind of impervious construction material of polyvinyl alcohol modification resistance to compression
Preparation method.
Background technique
Currently, China is in the developing period of economic construction, a large amount of engineering construction and pulls down and removes a building for reconstruction inevitably
Annual several hundred million tons of building waste is produced, building waste is divided into soil substantially and excavates rubbish（It is commonly called as dregs）, old building tears open
Except rubbish two major classes.But most clay, sandstone, rock are in the field of business for backfilling in the form of soil and sandstone respectively in preceding paragraph
Or it is processed into sandstone aggregate utilization, old building removes full sized brick watt, old metal, waste plastics, useless bamboo wood, cullet in rubbish etc.
Also it is actually recovered and utilizes, only remaining brickbat tile fragment, waste mortar, waste concrete block and roach are dropped.Building waste has
Recycling attribute, building waste pass through disposal of resources, and 95% or more can become the raw material of engineering construction and can be applied to construction
In engineering.
Summary of the invention
The present invention provides a kind of preparation method of impervious construction material of polyvinyl alcohol modification resistance to compression, and the present invention utilizes building rubbish
Rubbish, waste plastic and slag, in conjunction with pva powder, the building material surface of preparation forms resin layer, has compression strength
The performances such as height, good impact resistance, impermeability.
The present invention is achieved by the following technical solutions：
A kind of preparation method of the impervious construction material of polyvinyl alcohol modification resistance to compression, which is characterized in that include the following steps：
（1）The recycling of scrap feed material
a）After the major part of building waste is recycled, sundries therein is removed, respectively by coarse aggregate and carefully
The partial size of aggregate is crushed, and building waste coarse aggregate and building waste fine aggregate are obtained；
b）After waste plastic and dump slag are recycled, sundries therein is removed, obsolete material is crushed
With grinding, molding powder and slag powders are obtained；
（2）Fine aggregate mixing
a）By step（1）Resulting building waste coarse aggregate and lime stone, dolomite, calcium oxide, silica, rhodonite carry out
It is collectively disposed at jaw crusher after mixing by using screening technology, is repeated and is crushed to pellet diameter and reaches fine aggregate etc.
Grade；
b）By resulting mixing fine aggregate and step（1）Resulting building waste fine aggregate, portland cement, flyash, silicon ash,
Carbon nanotube is mixed, and then plus water and water-reducing agent, white oil continue to stir, and obtains mixture slurry；
（3）Mixing
a）By step（1）Step is added in resulting molding powder and slag powders（2）Pva powder is added in resulting mixture slurry
Continue stirring and dissolving, is slowly put into vacuum tank, continues 6 hours under 0.1MPa vacuum pressure；
b）Mixture slurry vacuum filtration machine is filtered, removal filtrate obtains solid, it after washing, is placed in baking oven, heat temperature raising,
It is stand-by after drying；
c）By the aggregate after drying pave it is sunny, at well-ventilated natural drying it is dry both the polyvinyl alcohol modification
The impervious construction material of resistance to compression.
Further, its chemical component of the slag mainly has：Silica, aluminium oxide, calcium oxide, magnesia, oxidation
Iron.
Further, the flyash is level-one flyash or second class powered coal ash.
Further, the water-reducing agent is High-efficiency polycarboxylic acid based water reducer, solid content 20%, water-reducing rate 25%.
It is an advantage of the invention that：
The present invention by building waste recycling crush to obtain coarse-fine aggregate, will waste plastic and dump slag recycling after be crushed and grinding,
Obtain molding powder and slag powders；It is crushed to pellet diameter again after coarse aggregate and lime stone etc. are mixed and reaches fine aggregate grade；
Fine aggregate and portland cement etc. are mixed to get mixture slurry；Molding powder and slag powders are added and pva powder is filtered and done
It is dry both to obtain the impervious construction material of polyvinyl alcohol modification resistance to compression.The present invention is by building waste and waste plastic and dump slag
Recycling, has well solved the very big problem of construction material former material consumption, and the material of recycling have compression strength it is high,
Lime stone, dolomite, calcium oxide, silica, rhodonite are combined, are added to by the performances such as good impact resistance, impermeability
The microstructure of pellet is changed in pellet, there is fabulous heat preservation and insulation, passes through polyvinyl alcohol, molding powder, slag powders
Compound incorporation, while increasing the adhesion strength of construction material, to achieve the purpose that enhance construction material toughness, show it
High-tension, good plasticity, high impact flexibility.Waste plastic can carry out cladding aggregate, form resin on the surface of aggregate
The gap of material internal can be filled in layer, improves its impermeability.The present invention utilizes building waste, waste plastic and slag, in conjunction with poly-
The building material surface of vinyl alcohol powder, preparation forms resin layer, has the property such as compression strength height, good impact resistance, impermeability
Energy.
