Description
Technical field
The present invention relates to a kind of fireproof heat insulating sound insulation cement polyphenyl formworks.
Background technology
It is energy saving at the same allow again people experience the safety of house with it is comfortable, this is the inexorable trend of social development.State
Family is not required nothing more than new building and is constructed using energy-saving design, to take energy saving remedial measure to Old building yet.Building energy conservation has been compeled
The eyebrows and eyelashes.It is desirable to the housing safety of oneself, energy antidetonation simultaneously wishes to resist historical high earthquake magnitude；Wish that building materials are fire-retardant, with profit
Fire control；Wish that room is kept the temperature, there is the sense of " cool in summer and warm in winter "；Wish that room sound insulation, the daily sound will not invade and harass neighbours.Past
Brick concrete structure obviously do not meet the demand of today, do not meet shockproof requirements not only, do not meet heat preservation energy-saving requirement more.It is past
Exterior wall enclosure structure is usually clay brick, thickness the Northeast be 365,490,620mm, the thermal coefficient mistake of this walling
Greatly, the left and right wall mean heat transfer coefficient 1.6W/ (mK).Reveal less than room air in the temperature of severe cold season, exterior wall inner surface
When point temperature, the inner surface of exterior wall just generates moisture condensation and causes inner wall surface mildew phenomenon.It is comfortable that this phenomenon can not only influence people
And health, while also resulting in indoor appliances and building structure damage；Also soundproof effect difference and its anti-seismic problem are more made us
Worry.
Thermal insulation material for external wall includes mainly three categories：
1. the inorganic heat insulation material based on mineral wool and mineral wool usually regards as non-automatic incombustible material, rock wool, mineral wool
For their thermal coefficient usually between 0.036~0.041W/ (mK), itself belongs to inanimate matter silicate under normal temperature condition
Fiber, it is non-combustible, but during being processed into product, organic binder or additive to be added sometimes, these are to product
Combustibility will produce certain influence.Therefore, rock wool, slag cotton products combustibility depend on wherein combustible binder
Number.
2. the organo-mineral complexing thermal insulation material based on adhesive powder-polystyrene granule thermal insulation mortar, usually regards as flame retardancy material
Material.Adhesive powder-polystyrene granule thermal insulation mortar is a kind of heat preserving and insulating material of organo-mineral complexing, and the volume of granular polystyrene about exists
80% or so, thermal coefficient is 0.06W/ (mK), and combustion rating is B1 grades, belongs to nonflammable material.Adhesive polystyrene grain is heated
When, the granular polystyrene generally comprised can soften and melt, but not burn.Since granular polystyrene is wrapped up by inorganic material,
Closed cavity will be formed after melting, at this time the thermal coefficient of the thermal insulation material can it is lower, heat transfer is slower, be heated overall process material
Volume change is zero.
3. the organic insulation material based on styrofoam, polyurethane and phenolic aldehyde, usually regards as combustible material.Polyphenyl second
Alkene foamed material is thermal plastic high polymer heat preserving and insulating material, and thermal coefficient is 0.041W/ (mK).When heated, usually occur
Softening and fusing.The heat distortion temperature of styrofoam is only 70~98 DEG C, and difference depends on selecting formula and post-processing approach, glass
It is 100 DEG C to change temperature.Polystyrene is all made of carbon hydrogen element, is substantially easily burnt, not fire retardant treated, and oxygen index (OI) is only
It is 18%；Heat liberation unit is larger when burning, while generating a large amount of cigarettes, by fiery after-contraction, fusing, causes to generate in outer heat preservation system
Cavity is flashed over and is burnt under state acutely, and the dropping of burning has igniting property.Hard foam polyurethane is a kind of macromolecule thermosetting
Property heat preserving and insulating material, thermal coefficient be 0.024W/ (mK), be optimal in all exterior wall organic insulation materials.It is poly-
Belong to highly flammable material on urethane foaming issues, oxygen index (OI) is only 16.5% when not doing flame retardant treatment；Thermosets by
Inflammable gas is usually decomposited when hot, forms charring layer after by fire, and the product of thermal decomposition and burning mainly has hydrogen cyanide, CO, different
Cyanate etc. also compares the toxicity research of polyurethane burning more.
For polyphenyl board exterior wall outer thermal insulation system, due to being that point is viscous, inherently there is the air layer being integrally connected to, fire in system
" air duct of igniting " is quickly formed when calamity makes fire spread rapidly.Although the use of the styrofoam in architectural exterior insulation layer being flame retardance poly
Benzene plate has certain self-extinguishment, but can still burn under fire conditions, and the fire retardant being added is after combustion, generates big
Amount toxic gas make one be poisoned and die or be first poisoned stupor then burn to death.High smokiness makes visibility be greatly affected when burning, makes
At psychological panic, escape difficulty, the work of putting out a fire to save life and property of fire fighter is also influenced.
The house built using cement polyphenyl formwork material can once solve above-mentioned whole issue：8 grades or more earthquakes can be resisted,
Its is energy-efficient, and wall thermal insulating is heat-insulated, and people is allowed to have sense cool in summer and warm in winter；Thermal insulator is not burnt, and nontoxic taste distributes；Wall, canopy face
It is heat preservation and soundproof setting；Moreover, compared with tradition or other heat-preserving buildings, indoor usable floor area increases, and saves template,
It is convenient to construct, and saving of work and time is notable, and the outstanding feature for having cost relatively low.
The material for constituting cement polyphenyl formwork body is rubber powder+granular polystyrene+a small amount of cement and water, and cement effect is more to strengthen
Fire resistance, the stability of insulating layer, while increasing the intensity of formwork, leave nature transition zone to plastering substrate.Formwork when construction
It can be used as building block and be put into wall shape as required, block is fixed with block gap with polyurethane foam glue, has spacing equal in formwork and phase
Mutually vertical grid-like hole, the interior arrangement reinforcing bar of hole and Cast-in-place concrete formation reinforced concrete framework, to meet force request.
