Description
Technical field
A kind of self-insulating concrete composite block of the present invention and preparation method thereof, is related to a kind of construction concrete heat-insulating
Building block and preparation method thereof, belong to Architectural Equipment field.It is more particularly to a kind of to be entered using the polystyrene foam ball of different size
Go after being surface-treated, the method for being prefabricated into polystyrene aggregate, manufactured thermal insulation concrete block and its preparation, to solve polyphenyl
Ethene particle is incubated inhomogenous problem directly as aggregate.
Background technology
At present, in building construction process, certain mix is carried out using discarded polystyrene foam particles and concrete
Close, then carry out being prepared into thermal insulation concrete, as the utilization of waste polystyrene foam, by the joyous of many building constructors
Meet, but also have mixing uneven low with compression strength, using polystyrene as the heat preserving aggregate of concrete, in industry
Interior, sanctified by usage is all the granules of polystyrene obtained by directly crushing polystyrene foam, then according to using need
Other concrete materials are adjusted, applicant is directed in existing document and retrieved, found in different patent documents, right
Also it is only the size that have adjusted granules of polystyrene in utilization of the polystyrene as the heat preserving aggregate of concrete, it is from root
There is no the characteristic for improving polystyrene aggregate in sheet, which limits applicable model of the polystyrene as the heat preserving aggregate of concrete
Enclose.
It is open（Bulletin）Number CN103011713A discloses a kind of Waste foam concrete insulation material and preparation method thereof,
It is characterized in that insulation material component and content are 2 millimeters ~ 10 millimeters granules of polystyrene：5% ~ 15%, cement：20% ~ 50%, bone
Material：15% ~ 25%, function regulator：0.2% ~ 3%, water：4% ~ 7%, all percentages are mass percent, primary raw material therein
Use waste polystyrene foam, although can also play certain insulation effect, use first by function regulator into
Point mixing, then 2-10mm granules of polystyrene and the aqueous solution of mediation are mixed uniformly mixed, then by polyphenyl
Ethene particle and other thermal insulation concrete materials mix, in mixed process, on the one hand because granules of polystyrene is relatively light in itself, and meeting
Float over above the concrete of mixing so that the granules of polystyrene in concrete slurry has localized clusters, after solidification
Intensity everywhere, heat-insulating property difference in concrete is larger, while used granules of polystyrene difference in size is larger, profile
Consistency of contour is relatively low, thus granules of polystyrene in stirring and other thermal insulation concrete materials bondability also each not phase
Together, it is difficult to control the homogeneity of integral heat insulation performance.
On the other hand, with 2 millimeters ~ 10 millimeters granules of polystyrene, these granules of polystyrene of different sizes prepare and
Into foamed concrete thermal-insulating material, in mixed process, may result in directly superposition contact between granules of polystyrene, or only
One layer of very thin cement is only spaced, due to granules of polystyrene size and difference, causes the insulation blocks being prepared into, internal polyphenyl
Ethene distribution of particles is uneven, respectively inconsistent to thermal conductivity factor, and its compression strength is not high, largely effects on the suitable of insulation material
Use scope.And it is standby directly to prepare building block using existing Waste foam concrete insulation material, due to being granules of polystyrene
Mix concrete forms, and the outer surface out-of-flatness for the thermal insulation concrete block for causing to prepare using extra, it is necessary to brush one layer
Concrete, building block is prepared using granules of polystyrene mix concrete, meeting is exposed outside after caused granules of polystyrene mixing
Face, after drenching with rain, the problem of granules of polystyrene comes off from building block.
The content of the invention
