Abstract
The invention discloses a sintering-free exterior wall face brick with a thermal insulation function and low water absorption rate. The sintering-free exterior wall face brick is mainly applied on a wall without exterior insulation. By taking three light thermal insulation aggregates of ceramic sand, vitrified micro bubbles and fly ash cenospheres as skeleton materials and zinc fluosilicate as a capillary crystalline waterproof material, the sintering-free exterior wall face brick has the advantages of light weight, high strength, good thermal insulation and low water absorption rate, and can be molded by compression and manufactured to be 15mm-25mm thick. A formula of a green body of the face brick is as follows (mass %): 0.24-0.38 of general cement, 0.11-0.17 of high alumina cement, 0.01-0.10 of emulsion powder, 0.35-0.50 of ceramic sand, 0.20-0.30 of vitrified micro bubbles, 0.10-20 of fly ash cenospheres, 0.01-0.08 of zinc fluosilicate, 0.01-0.07 of reinforced fiber, and 0.01-0.07 of high-efficiency water reducing agent.
Description
Technical field:
The invention belongs to a kind of functional form exterior wall surface decorative material, specifically is a kind of exposed wall facing brick that does not need sintering, this face brick light weight, high-strength, have incubation and thermal insulation function, and water absorption rate is very low.This low water absorption face brick with incubation and thermal insulation function is mainly used in aerated concrete masonry wall, the core hole that the hollow concrete blockwork of inserting warming plate etc. has heat insulating effect and the building exterior wall face that need not carry out external wall outer insulation; Except decorative effect is provided, can also eliminate heat bridge and the thermal and insulating performance that increases body of wall.
Background technology:
On the one hand, the quality of present non-sintering exposed wall facing brick unit volume is heavy, can not make very thickly, does not also possess incubation and thermal insulation function.If directly adopt the light heat-insulating aggregate to replace the sand preparation to have the non-sintering face brick of incubation and thermal insulation function, have that thermal insulation aggregate cylindrical compress strength is low can not to bear forcing press produces in the compression moulding process pressure and broken and high two problems of face brick water absorption rate.
On the other hand, the hollow concrete blockwork etc. of inserting warming plate in various aerated concrete masonry walls, the core hole has the external wall of heat insulating effect, has had certain incubation and thermal insulation function, and has not needed to carry out the external wall outer insulation construction again.But this type body of wall is being built mortar joint by laying bricks or stones and there is heat bridge in structure position places such as beam, post, reduces the heat insulating effect of body of wall.Use finish materials such as present coating, sintering and non-sintering face brick to be difficult to solve this type problem, and if use the face brick of common weight sintering or non-sintering to paste because there is potential safety hazard in the quality escheat.
Summary of the invention:
To insert warming plate hollow concrete blockwork etc. and do not have build by laying bricks or stones mortar joint and beam, the post etc. of the external wall of external thermal insulation system to locate there is heat bridge and use ordinary sinter or potential safety hazard that non-sintering face brick exists in order to overcome in aerated concrete masonry wall, the core hole, the present invention provides a kind of light weight of low water absorption, high-strength, novel non-sintering face brick that thermal and insulating performance is good.This face brick is compound as cementitious materials by high-strength, high-early-strength cement and redispersible polymer toner; Sand is as framework material; On the basis of fiber as the non-sintering exposed wall facing brick of reinforcing material, replace sand, add permeable crystalline waterproofing material again and obtain having the non-sintering exposed wall facing brick of incubation and thermal insulation function with three kinds of light thermal-insulation aggregates.The face brick that obtains like this has the characteristic that light weight, compressive strength and rupture strength are high, thermal and insulating performance is good, water absorption rate is very low, and can be prepared into certain thickness, more increases heat insulating effect.
The present invention solves its technical problem and adopts following technical scheme:
Adopt high-early-strength cement and redispersible polymer toner (latex powder) compound as cementitious materials; Pottery sand, glass bead and three kinds of light heat-insulating aggregates of coal fly ash hollow micro bead are as framework material; Fiber is as reinforcing material, and the interpolation zinc fluosilicate obtains having the non-sintering exposed wall facing brick base substrate of incubation and thermal insulation function as permeable crystalline waterproofing material.Because the high-strength light of base substrate can be produced the big face brick of thickness, for example produces the face brick of 15mm～25mm thickness.
The prescription of said base substrate is (quality %):
General cement 0.24～0.38; High alumina cement 0.11～0.17; Latex powder 0.01～0.10; Pottery sand 0.35～0.50; Glass bead 0.20～0.30; Coal fly ash hollow micro bead 0.10～20; Zinc fluosilicate 0.01～0.08; Fortifying fibre 0.01～0.07; High efficiency water reducing agent 0.01～0.07.
Said general cement is that strength grade is 42.5 grades and above construction industry general cement commonly used; Said latex powder is VAE and modification VAE class latex powder; The thin heat preserving aggregate of particle diameter below 5mm that said pottery sand produces when being the calcining haydite; Said glass bead is that performance meets the II series products among the building material industry standard JC/T1042 " expanded and vitrified small ball "; Said coal fly ash hollow micro bead is the tiny balloon material of the surperficial vitreous of sorting from flyash; Said fortifying fibre is that the organic synthesis weak point that is used for the cement concrete enhancing chops up fiber; Said high efficiency water reducing agent is a high efficiency water reducing agent general in the cement concrete.
This face brick base substrate constituent is made base substrate through compression moulding, maintenance; And use fluorine carbon building coating or polyacrylate-organosilicon copolymerization building coating combination with decorative surfaces, process light weight, high-strength, thermal and insulating performance good and water absorption rate is low non-sintering face brick.
The invention has the beneficial effects as follows: three kinds of light heat-insulating aggregates form closs packing and have very high cylindrical compress strength; Can bear the pressure of non-sintering face brick forcing press in the manufacture process of compression moulding; Make aggregate be unlikely broken, make face brick keep light weight and thermal and insulating performance; Permeable crystalline waterproofing material can form crystalline material in the capillary porosity of water mudrock structure and to stop up structure that pore makes material fine and close more and produce water proofing property, makes face brick have very low water absorption rate.The addition that simultaneously, can significantly reduce the redispersible polymer toner owing to the introducing of permeable crystalline waterproofing material reduces the manufacturing cost of face brick.
Below in conjunction with embodiment the present invention is described further.
The specific embodiment, non-limiting examples is described below:
Embodiment
(1) body recipe (quality %) is:
General cement 0.29～0.36; High alumina cement 0.13～0.16; Latex powder 0.03～0.07; Pottery sand 0.38～0.48; Glass bead 0.23～0.27; Coal fly ash hollow micro bead 0.13～17; Zinc fluosilicate 0.03～0.06; Fortifying fibre 0.02～0.05; FDN high efficiency water reducing agent 0.02～0.05.
