Description
Technical field
The present invention relates to building material technical field, be specifically related to a kind of EPS-foam cement composite self-insulation L-shaped corner
The preparation method of building block.
Background technology
Along with the energy, the increasingly sharpening of crisis of resource, it is necessary to actively advocate green building, the building reason of strengthening building energy conservation
Read.Use the various materials for wall with heat insulation function, not only can save ample resources, moreover it is possible to reduce energy resource consumption, reduce ring
Environment pollution.
In this context, external thermal insulation system is developed on an unprecedented scale.But through enforcement in recent years and application, find
The energy-conservation way wrapped to body of wall, the most fundamentally solves the power saving of construction wall building enclosure, and brings
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 side of wall reform development
To, increasingly get the nod.
Foam cement is that foaming agent is the most fully foamed by the foamed system by foaming machine, and by foam and water
The Binder Materials slurries such as mud uniformly mix, and then carry out cast-in-place construction or mould molding by the pumping system of foaming machine, through certainly
So maintenance and a kind of lightweight fireproof insulating material containing a large amount of sealed porositys of being formed, its advantage is stable performance, deformation system
Number is little, and not only fire protection flame retarding but also aging resistance, service life is relatively long, and difficulty of construction is relatively small, and engineering cost is relatively low, can
With cycling and reutilization.But, foam cement is due to the limitation in its formula and technical matters, and most of article constructions are single, no
Enough stable, heat conductivity is higher, and heat-insulating property is not enough, and intensity is low, and pliability is poor, frangible rapid wear.
Polystyrene foam (Expanded Polystyrene is called for short EPS) is a kind of light type high-molecule polymer.Organic
Class EPS insulation material have lightweight, pliability good, machinability good, the most broken, compactness is high, good effect of heat insulation
Advantage, shortcoming is that fire safety performance is not enough, and deformation coefficient is big, the most ageing-resistant, exists certain tired in practice of construction is applied
Difficult.
How EPS combined with foam cement technology, overcome respective defect, comprehensive performance both advantages, preparation
Go out a kind of Novel compound self heat-insulation building block, be one brand-new research topic of building material industry.
The existing EPS building block manufactured that combines with foam cement mainly has two kinds of forms:
A kind of is the composite heat insulation block of EPS-foam cement sandwich structure, and the centre position of this building block is EPS warming plate,
Both sides are foam cement；During preparation, the most first insert EPS warming plate, then pouring foaming cement in mould remaining space
Slurry, becomes insulation blocks through sawing after maintenance.
Another kind is to utilize Making mold to become the middle foam cement building block having various hole, then is cut into by EPS sheet and send out
The shape that the hole of bubble cement block matches, inserts in the hole, and forms heat insulating composite building block.
Both structures, first all must use particular manufacturing craft when manufacturing foam cement building block, and production cost is higher, and second protects
Temp effect is the most as one wishes, has much room for improvement, and still needs to secondary isothermal holding during as outer wall body.
Summary of the invention
The technical issues that need to address of the present invention are that the defect overcoming existing single insulating wall material, it is provided that a kind of
The preparation method of EPS-foam cement composite self-insulation L-shaped wall corner building block, it is by organic material EPS and inorganic material foam cement
Combine, constitute composite, give full play to the respective advantage of bi-material, overcome respective deficiency, possess the most easy to crack, long
The Good All-around Properties such as phase heat insulation effect is good, high-strength light, insulation, sound-adsorbing sound-insulating hung, construction is simple, cost is low, are one
Plant and integrate building enclosure and the new material of wall thermal insulating function, meet the advanced direction of materials for wall development, be particularly suitable for
