Abstract

The utility model relates to a fireproof foam sandwich board, on the polystyrene foam particle surface of which a magnesium oxychloride cement layer is coated. The fireproof foam sandwich board comprises basal plates on the two sides and an intermediate fireproof insulating layer, wherein the fireproof insulating layer is a hybrid fireproof insulating layer formed by mixing polystyrene foam particles and magnesium oxychloride cement. The utility model has the advantages that the magnesium oxychloride cement is coated around the foam particles in the fireproof foam sandwich board, the role of stopping the secondary combustion of the foam particles can be played under the obstructing action of the magnesium oxychloride cement, and the A grade noncombustible standard can be achieved, so as to satisfy the building fire-fighting requirements; and besides, the manufacturing process is simple, the operation is easy, and the energy consumption can be reduced.

Description

The fire-type foam battenboard

[affiliated technical field]

The utility model relates to a kind of sheet material, relates in particular to the fire-type foam battenboard that a kind of polystyrene foam particle surface is coated with the magnesia oxychloride cement layer.

[background technology]

Polystyrene foam plate production is mature technique very, uses very general.At first polystyrene plastics is foamed by steam, become the foam particle of lightweight, then foam particle is sucked framed.By steam foam particle is bonded into integral body.The cystosepiment that this technology is produced has advantage in light weight, that coefficient of thermal conductivity is little, is used for heat-insulating material.

But, aspect building fire protection, use and just demonstrate weak point.Polystyrene foam burns easily, in case meet fire, can prolong combustion by polystyrene foam plate, and emit a large amount of toxic gases.In order to solve polystyrene foam easy firing problem, brainstrust adds fire retardant in the polystyrene foam plate particle, oxygen index (OI) (is meant that under rated condition sample is in oxygen, nitrogen mixed gas stream, keep the required minimum oxygen concentration of smooth combustion, represent with the shared percentage by volume of oxygen.The high expression of oxygen index (OI) material is nonflammable, and the low expression of oxygen index (OI) material burns easily, it is generally acknowledged that oxygen index (OI)＜22 belong to combustible material, and oxygen index (OI) belongs to combustible material, oxygen index (OI) between 22～27〉27 genus nonflammable materials.) can reach more than 30, become nonflammable material.But the requirement of building fire protection is more and more higher, and the fire-protection rating of many constructional materialss must reach does not fire the A level.By prior art, can only be flammable, or nonflammable material, can not reach and not fire the A level, do not satisfy the building fire protection requirement.

[summary of the invention]

The purpose of this utility model is to provide a kind of fire-type foam battenboard, because the foam particle surface in this plate is coated with magnesia oxychloride cement, be subjected to the iris action of magnesia oxychloride cement, play and stop foam particle to prolong the purpose of combustion, reach and do not fire the A level, thereby satisfy the building fire protection requirement, the cystosepiment that the solution prior art is produced can not reach the purpose of not firing the A level, can't satisfy problems such as building fire protection requirement.

Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: the fire-type foam battenboard, it is characterized in that comprising the substrate and the middle fireproof thermal-insulation layer of both sides, described fireproof thermal-insulation layer is the mixture fireproof thermal-insulation layer that polystyrene foam particle mixes with magnesia oxychloride cement.Both sides at fireproof thermal-insulation layer are compounded with substrate, the bulk strength that helps improving.The thickness of substrate can require to form corresponding thickness according to actual strength.

The manufacture craft of this fire prevention foam battenboard: preparation magnesia oxychloride cement; Polystyrene foam grain and magnesia oxychloride cement are are fully mixed and stirred, make the full and uniform coating magnesia oxychloride cement in foam particle surface; With the foam particle that mixes make fireproof thermal-insulation layer (its operation is: the polystyrene foam particle that will mix and stir magnesia oxychloride cement is sent into template, by mechanical rolling formation, perhaps artificial rolling formation; Also the polystyrene foam particle that stirs can be sent into mould, according to die forming).The operation of this preparation method is simple, and is easy to operate.

Magnesia oxychloride cement forms by magnesia, magnesium chloride, modifier and water are composite.Modifier is the abbreviation of modified additive, and the every Admixture that can improve the various performances of magnesium cement all can be referred to as modifier.It improves water resistance and mechanical property to improving the structural stability of magnesia oxychloride cement, and surface halide accumulation resistance, scum, distortion, shortly coagulate, slow setting, increasing the operation workability all has and important effect.

Magnesia oxychloride cement produces fire retardation to foam particle, plays to stop foam particle to prolong the purpose of combustion, reaches and does not fire the A level, thereby satisfy the building fire protection requirement, simultaneously, also becomes the adhesive that foam particle is bonded into cystosepiment.Saved with steam the foam particle secondary action is carried out bonding, the consumption of also just having saved the energy.

As the further of technique scheme improved and replenish, the utility model adopts following technical measures: described fireproof thermal-insulation layer is formed by the surface coating magnesia oxychloride cement layer mixing of each polystyrene foam particle.

Described polystyrene foam particle is the foam particle that the polystyrene plastics particle forms by the steam foaming, and described magnesia oxychloride cement layer coats the surface of each foam particle fully.

Described substrate comprises glass layer and infiltrates through glass layer and mutual bonding magnesia oxychloride cement layer.The setting of glass layer has the effect of enhancing to the intensity of magnesia oxychloride cement layer.Wherein, the thickness of the number of plies of glass layer, magnesia oxychloride cement layer can require to select the corresponding number of plies and thickness to carry out compound according to actual strength.In addition, the material of glass layer not only is a glass fiber, can also be for nonwoven etc. other have and strengthen material anti-shearing, bending resistance.

The beneficial effect that the utlity model has: be coated with magnesia oxychloride cement around the foam particle in this fire-type foam battenboard, be subjected to the iris action of magnesia oxychloride cement, play the purpose that the prevention foam particle prolongs combustion, reach and do not fire the A level, thereby satisfy the building fire protection requirement; And its production process is simple, and is easy to operate, simultaneously, and consumption that can also energy conservation.
