Description
Technical field
The present invention relates to building material technical field, be specifically related to the building block of a kind of XPS-foam cement composite self-insulation stalk.
Background technology
Along with the energy, the increasingly sharpening of crisis of resource, actively must advocate green building, the facade lighting of strengthening building energy conservation.Adopt the various materials for wall with heat insulation function, not only can save ample resources, can also energy consumption be reduced, reduce environmental pollution.
In this context, external thermal insulation system obtains and develops on an unprecedented scale.But through enforcement in recent years and application, find the energy-conservation way wrapped to body of wall, fundamentally do not solve the power saving of construction wall building enclosure, and bring the various problems such as safety, construction, cost.
Novel from energy-conservation walling and heat insulation system thereof because of its obvious energy-saving effect, represent the direction of wall reform development, more and more get the nod.
Foam cement is mechanically fully foamed by whipping agent by the foamed system of foaming machine, and by the gelling material such as foam and cement slurry Homogeneous phase mixing, then cast-in-place construction or mould molding is carried out by the pumping system of foaming machine, a kind of lightweight fireproof insulating material containing a large amount of sealed porosity formed through natural curing, its advantage is that stable performance, deformation coefficient are little, not only fire protection flame retarding but also anti-aging, work-ing life is relatively long, difficulty of construction is relatively little, engineering cost is relatively low, can cycling and reutilization.But foam cement is due to the limitation in its formula and technical matters, and most of article construction is single, and stable not, thermal conductivity is higher, and heat-insulating property is not enough, and intensity is low, and snappiness is poor, frangible rapid wear.
Extrusion moulding type polystyrene cystose (be called for short XPS), it is that raw material adds other supplementary material with poly-containing thing with polystyrene resin, by heating mixing injecting catalyst simultaneously, then extrusion molding extrusion molding and the rigid foam plate that manufactures.
XPS has perfect closed honeycomb structure, this structure allow XPS plate have lightweight, intensity is high, snappiness good, workability is good, not easily broken, compactness is high, good effect of heat insulation, water-absorbent are extremely low (absorbing water hardly), the advantage of anti-aging (normally using almost without degradation and decomposition phenomenon), shortcoming is that fire safety performance is not enough, in practice of construction application, there is certain difficulty.
How XPS is combined with foam cement technology, overcome respective defect, comprehensively play both advantage, prepare a kind of Novel compound self heat-insulation building block, be the research topic that building material industry one is brand-new.
The existing XPS building block manufactured that combines with foam cement mainly contains two kinds of forms:
Be a composite heat insulation block for XPS-foam cement sandwich structure, the mid-way of this building block is XPS warming plate, and both sides are foam cement; During preparation, first insert XPS warming plate in a mold, then in mould remaining space pouring foaming cement slurry, become insulation blocks through sawing after maintenance.
Another kind utilizes Making mold to become the middle foam cement building block having various hole, then XPS plate is cut into the shape matched with the hole of foam cement building block, inserts in the hole, form heat insulating composite building block.
These two kinds of structures, all must use particular manufacturing craft during the first manufacture foam cement building block, production cost is higher, and the second heat insulation effect is also as one wishes not to the utmost, has much room for improvement, and still needs secondary isothermal holding as during outer wall body.
Summary of the invention
The technical issues that need to address of the present invention are just the defect overcoming existing single insulating wall material, the preparation method of a kind of XPS-foam cement composite self-insulation stalk building block is provided, organic materials XPS and inorganic materials foam cement combine by it, form matrix material, give full play to bi-material advantage separately, overcome respective deficiency, possess not easy to crack, long-term heat preservation is respond well, high-strength light, heat insulating, sound-adsorbing sound-insulating hung, construction is simple, cost is low waits Good All-around Property, it is a kind of novel material integrating building enclosure and wall thermal insulating function, meet the advanced direction of materials for wall development, be particularly suitable for the construction in passive type house.
