Abstract
The invention relates to a building flame-retardant heat insulation wall, which comprises a wall body (1), an adhering layer (2), a flame-retardant heat insulation layer (3), a moisture-proof layer (4), an anti-cracking protecting layer (5) and a finish layer (6), wherein the flame-retardant heat insulation layer (3) comprises an outer fireproof layer (31) and an inner organic heat insulation layer (32), the fireproof layer (31) is made of vitrified microsphere heat insulation mortar, the organic heat insulation layer (32) is added with a flame-retardant agent, and the anti-cracking protecting layer (5) comprises a polymer anti-cracking plastering mortar (51) and a reinforcing net (52). The building flame-retardant heat insulation wall has the advantage that the non-halogen flame-retardant agent is added into the organic heat insulation layer, and the outer fireproof layer does not influence the heat insulation property of the system, and can form the comprehensive flame-retardant protecting on the periphery of the organic heat insulation layer, so the safety of the system is guaranteed.
Description
Technical field
The invention belongs to energy saving building field, particularly relate to a kind of building fire-retardant heat insulation body of wall.
Background technology
China's energy resources are relatively deficient, and long-term energy supply faces a severe challenge, economic development and energy supply and demand environment contradiction.Building energy conservation is the main contents performing national environmental protection and energy conservation policy, is the important component part implementing national economy sustainable development.Along with constantly improving and development of energy-saving building technology, External Walls Heating Insulation is widely deployed in construction work because of the advantage of self, becomes the main flow of building thermal-insulation energy-saving situation gradually, plays in building trade the effect become more and more important.Exterior wall heat-preserving system is compounded in outside structure wall, the combustibility of itself and fire endurance, is that infringement or the spreading further of the intensity of a fire of prevention building itself of opposing adjacent architectural fire is all important.
Under the promotion of National Technical policy and energy conservation standard, China more and more payes attention to for the development of the fireproofing technique of external-wall heat-insulation material.The organic insulation materials such as traditional EPS, XPS or PU, although be difficult to the building fire protection requirement reaching national regulation, but because of inexpensive, insulation, the advantage such as insulation effect is good, on the basis considering economy and practicality, stop completely to use this kind of material still to acquire a certain degree of difficulty at present, be still widely used in building exterior wall heat preserving.Be necessary to develop some new flame-retarded technologies to guarantee organic insulation material safety in use, do not affect the heat insulation effect of system simultaneously.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art; a kind of building fire-retardant heat insulation body of wall is provided; halogen-free flame retardants is added with in organic heat-insulating layer; and organic heat-insulating layer outer wrapping last layer kervit microbead insulated sand slurry fireprotection layer; can while the heat insulating ability not affecting system; comprehensive obstruct burning is carried out to organic heat-insulating layer, practical safety.
For achieving the above object, the technical scheme taked of the present invention is as follows:
A kind of building fire-retardant heat insulation body of wall; comprise body of wall (1), tack coat (2), fire-retardant heat insulation layer (3), damp-proof course (4), anti-cracking protective layer (5) and finish coat (6); described fire-retardant heat insulation layer (3) comprises the fireprotection layer (31) and inner organic heat-insulating layer (32) that are surrounded by; described fireprotection layer (31) is kervit microbead insulated sand slurry; be added with fire retardant in described organic heat-insulating layer (32), described anti-cracking protective layer (5) comprises polymers anti-cracking plastering mortar (51) and reinforcing mat (52).
Preferential, described adhesive linkage (2) is polymer bonding mortar.
Preferential, described organic heat-insulating layer (32) is extrusion molding polystyrene polyfoam or molded polystyrene foams plastics.
Preferential, the fire retardant added in described organic heat-insulating layer (32) is expanding halide-free fire-retardant.
Preferential, described damp-proof course (4) is organic silicon rubber.
Preferential, the reinforcing mat (52) in described anti-cracking protective layer (5) is alkaline-resisting reinforced grid cloth or galvanized steel wire netting.
Preferential, described finish coat (6) is fluorocarbon coating.
Beneficial effect of the present invention is as follows:
(1) outside of organic heat-insulating layer (32) is comprehensive is wrapped in one deck kervit microbead insulated sand slurry fireprotection layer (31); because himself having good insulation, thermal insulation; so do not affect the heat insulating ability of system, simultaneously can the defects such as more organic insulation material fireproof performance is poor, intensity is low.
(2) what add in organic heat-insulating layer (32) is halogen-free flame retardants, can prevent Halogen fire proofing from can produce a large amount of smog and poisonous corrosive hydrogen halides gas in fire-retardant process, cause secondary to endanger.
(3) existence of organic silicon rubber damp-proof course (4), can reduce the water absorption rate of kervit microbead insulated sand slurry fireprotection layer (31), ensures the stability of heat insulation system.
accompanying drawing illustrates:
Fig. 1: a kind of side, sectional structural representation building fire-retardant heat insulation body of wall of the present invention.
detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the invention will be described further.
