Description
Technical field
The present invention relates to a kind of foam glass thermal insulation material and preparation method thereof.
Background technology
Current China is the country of annual new building amount maximum in the world, is counted according to 2015, and China's building total amount is
Up to 51,900,000,000 m2, annual newly constructed house area is up to 2,000,000,000 m2, equivalent to the 50% of the annual new building in the whole world.It is existing in China
In building, energy saving building only accounts for 1% or so, and a large amount of old buildings are badly in need of carrying out reducing energy consumption.Although the newly-increased building of China is basic
Energy conservation standard instantly can be met, but wherein more than 95% belongs to high energy consumption building, and unit construction area adopts energy consumption for developed country
More than 3 times of new building.Country's materials for wall energy consumption and the nearly 150,000,000 tons of fire coals of building heating energy consumption, build at present
Energy consumption ratio shared in AND ENERGY RESOURCES CONSUMPTION IN CHINA total amount increases to 2015 from the 10% of late 1970s
27.6%.However, china natural resources occupancy volume is less than the 1/5 of world average level, it can be seen that, the novel wall material of energy-conserving and environment-protective
The big clay brick of material substitution energy consumption oneself through very urgent.
Foam glass thermal insulation material as a kind of emerging porous ceramics, due to having had that density is small, intensity is high concurrently, insulation, every
The good characteristic such as hot and fire-retardant, it has also become a kind of new building insulation material and be widely used in building load-bearing, insulation and
Sound-absorbing wall etc..Foam glass is typically to be mixed into the additives such as foaming agent, forming agent in basic components material, is molded in special die
After place into Muffle furnace be heated to melting, foam, the technique such as foam stabilizing and formed, typically by glass phase, crystal and three, stomata
It is grouped into.Wherein domestic and foreign scholars are most of has prepared foam glass by glass, glass chip by sintering process.
Such as：Fang etc. (Construction and Building Materials, 2017,134,358-363) is former with cullet
Material, Li2CO3It is foaming agent in 750 DEG C of synthesizing foamed glass；Andre ' C.Bento etc. (Ceramics International,
2013,39,2423-2430) by raw material of discarded glass, sodium hydroxide be foaming agent, TiO2For reinforcing agent synthesizing foamed glass.
Higher to ingredient requirement but both preparation methods are using glass as raw material, industrialized mass production is implemented more difficult.With
Attention of the people to preserving the ecological environment, it is that raw material fires foam that recent domestic scholar, which is begun attempt to solid waste,
Glass, such as money general (silicate journal, 2014,42,0454-5648) are made lime-ash with consumer waste incineration and then added a small amount of
Glass is the obtained foam glass of foaming agent with calcium carbonate, but such a method complex manufacturing technology, and energy consumption is of a relatively high.
The content of the invention
To avoid the deficiency present in above-mentioned prior art from pointing out, the invention provides a kind of foam glass thermal insulation material and
Its preparation method, it is intended to simplify manufacture craft, the reduction cost of material of existing foam glass, while ensureing the property of foam glass
Energy.
The present invention adopts the following technical scheme that to realize goal of the invention：
The foam glass thermal insulation material of the present invention, its composition of each raw material by weight is：The parts by weight of black cotton regur soil 30~55,
The parts by weight of basalt 15~35, the parts by weight of calcium carbonate 0.2~0.5, the parts by weight of sodium hydroxide 10~15, the weight of waterglass 15~20
Part.
Said ratio be applicants experimentally found that preferably proportioning, as long as in optional scope adjust black cotton regur soil,
The proportioning of basalt and calcium carbonate etc., can prepare the foam glass for meeting national standard.It should be understood that, by
It is limited in test number (TN), therefore is not excluded for also other feasible proportionings for being not belonging to above-mentioned optional scope.
The preparation method of foam glass thermal insulation material of the present invention, comprises the following steps：
(1) black cotton regur soil and basalt are crushed first；Then by the black cotton regur soil and basalt after crushing and calcium carbonate by proportioning
Mixing, grinding is uniform, obtains batch mixing；
(2) sodium hydroxide is dissolved in waterglass, obtains forming agent；
(3) batch mixing is fully mixed with the forming agent, pre-molding in injection mould is then still aging, most
After be stripped, obtain just base；
(4) the just base is placed in Muffle furnace and calcined, then cool to room temperature with the furnace, that is, obtained the foam glass and protect
Adiabator.
It is preferred that, it is that black cotton regur soil and basalt powder are broken to the mesh of particle diameter mesh number >=400 in step (1).
It is preferred that, the temperature calcined described in step (4) is 850~900 DEG C, 15~45min of soaking time.
It is preferred that, still aging temperature described in step (4) be normal temperature, time be 4-8h.
Above-mentioned optimum condition be equally applicants experimentally found that the step such as crushing, calcining preferably execution bar
Part, as the change of raw material proportioning, the change above-mentioned condition of the not equal factor of equipment state can be adjusted neatly.
Beneficial effects of the present invention are embodied in：
1st, the invention provides it is a kind of using widely distributed black cotton regur soil and basalt as major ingredient, by foaming agent of calcium carbonate,
Using sodium hydroxide and waterglass as the foam glass preparation method of cosolvent and forming agent, low raw-material cost, technique are simple, easy
In industrialized production, gained foam glass excellent combination property has filled up the blank that direct use clay makes foam glass, can
For various different fields.
2nd, the foam glass thermal conductivity factor that is obtained of the present invention is small, light weight, intensity higher than 3 times of country and professional standard,
The performance such as thermal conductivity factor and intensity reaches American Society Testing and Materials ASTM C552-14 requirement, is that one kind can extensive use
Engineering construction insulation material.
3rd, black cotton regur soil and basalt are widely distributed as the major ingredient of foam glass raw material of the present invention, can gather materials on the spot, not only
The difficulty that raw material conveyer belt comes can be reduced, the production cost of product is also reduced, improves economic benefit.
