Abstract
The invention relates to special fireproof mortar of a plastic extrusion plate. A fireproof protection layer is formed at the surface of the plastic extrusion plate, can act as the function of isolating oxygen and enables the oxygen not to directly contact with the extrusion molding plate, thereby avoiding the generation of a combustion reaction. The mortar comprises the following components: 20-50% of cement, 20-60% of sand, 2-10% of dispersible emulsion powder, 0-40% of inorganic composite material and 0.5-10% of organic composite material.
Description
Technical field
The present invention relates to building material field, particularly a kind of prevention and reduce extruded sheet in the architectural exterior insulation engineering engineering site deposit with construction process in the fireproof mortar of fire hazard.
Background technology
Extruded sheet is a kind of lagging material of excellent property, be widely used in the interior system of external wall outer insulation, but because its inflammable performance on the construction site of situation complexity, very easily causes fire.Domestic architecture exterior wall insulating materials and the system's fire failure of taking place in succession causes very serious loss for the country and people's lives and properties in the recent period, also causes bigger society and politics influence simultaneously, caused the extensive concern of various circles of society.
Burning needs just can carry out under certain condition, and promptly combustiblematerials, ignition dope and three conditions of thermal source exist simultaneously.When catching fire, the object of contiguous thermal source under the effect of heat, at first skin-material is initiated burning, and flame spreads towards periphery, and the material that is in material internal is difficult to ignite.So it is a kind of surface combustion phenomenon that incendiary is propagated, its velocity of propagation is relevant with the material combustion performance, and is also relevant with material surface situation and degree of exposure.
The fire-retardant way of existing extruded sheet is to add fire retardant in raw material, and reduction polymericular weight and viscosity can melt when polymkeric substance is heated, drip when being heated again, thereby plays the effect of fire-retardant fireproof.But in the middle of practical application, simple fire retardant interpolation is difficult to reach the fire-retardant requirement of B1 level; And in the middle of heat insulating work stores, uses outside exterior wall, because how situation complexity, burning things which may cause a fire disaster point just are very easy to cause disaster hidden-trouble on the building site.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists; a kind of fireproof mortar that is specifically designed to extruded sheet is provided, and it forms one deck fireproof jointing sheath on the extruded sheet surface, and it can play the effect of starvation; oxygen can not directly be contacted with extruded sheet, thereby avoid the generation of combustion reactions.When running into naked light, can prevent that the extruded sheet top layer from igniting and slow down heat to the transmission of extruded sheet and guarantee that the extruded sheet surface temperature is unlikely to rise De Taigao within a certain period of time, make it can bear structural load normally.Fireproof mortar has good heat insulation back-fire relief effect, can effectively suppress the burning and the propagation of extruded sheet
The object of the present invention is achieved like this: described fireproof mortar mainly contains cement, fine sand, redispersable latex powder, inorganic additives and organic additive and forms, constitute the fireproof system of inorganic compounding, have fabulous heat insulation back-fire relief effect, can and effectively suppress the burning and the propagation of extruded sheet.
Cement can be a kind of in silicate cement, ordinary Portland cement, Portland blast, portland-pozzolan cement, Portland fly ash cement, composite Portland cement, the high-alumina cement in the described mortar.
Inorganic additives is flyash, attapulgite, forges in kaolin, water-ground limestone, grey calcium, calcium hydroxide, GBFS, wilkinite, talcum powder, mica powder, silica powder, wollastonite powder, zeolite, diatomite, the polynite one or more in the described mortar.
Redispersable latex powder is vinyl acetate and ethylene copolymer in the described sand, vinyl acetate and ethene and higher fatty acid vinyl acetate terpolymer rubber powder, vinyl acetate and higher fatty acid vinyl acetate copolymerization rubber powder, acrylate and styrene copolymerized rubber powder, vinyl acetate and higher fatty acid vinyl acetate and ethylene chloride terpolymer rubber powder, vinyl acetate and acrylate and higher fatty acid vinyl acetate terpolymer rubber powder, vinyl acetate homopolymerization rubber powder, in vinylbenzene and the butadiene copolymer rubber powder one or more.
Organic additive is one or more in treated starch, hydroxypropyl methyl cellulose ether, sulfonated lignin, trimeric cyanamide and derivative thereof, beta-naphthalenesulfonic-acid formaldehyde condensation compound, tetramethylolmethane, polyvinyl alcohol, sulfonated melamine compound resin, tripoly phosphate sodium STPP, dodecane sulfonate, the higher alcohols in the described mortar.
The composition of described mortar and proportioning are: cement 20～50%; Sand 20～60%; Redispersable latex powder 2～10%; Inorganic composite materials 0～40%; Organic composite material 0.5～20%.
The form of construction work that described mortar is taked can be spraying or roller coating.
