Abstract
The utility model discloses a flame-retardant type polyurethane hard bubble heat-preservation plate which is used for heat preservation of internal and external wall bodies of a building. The performance of the heat-preservation plate is better than that of an expansive polystyrene plate (EPS plate) and a common heat-preservation sand pulp. The heat-preservation plate can meet the needs of lessening weight, lowering cost, saving energy and reducing consumption, and has the characteristics of convenient cutting, easy sticking, simple construction, convenient coloring, beautiful appearance and long service life; therefore, the heat-preservation plate is particularly suitable for being used as the heat-preservation material for the external wall. The flame-retardant type polyurethane hard bubble heat-preservation plate is composed of a panel and a flame-retardant type polyurethane hard bubble layer, and the flame-retardant type polyurethane hard bubble layer is connected with the panel after bubbling on the panel.
Description
Technical field
The present invention relates to a kind of warming plate, more specifically to a kind of flame-retardant polyurethane warming plate that hard bubbles.
Background technology
In recent years, also more and more higher to the insulation requirement of house wall along with the raising of people's lives level, using more at present, external-wall heat-insulation material has expanded polystyrene plate (EPS plate), composition silicate (or rare earth is compound) thermal insulation mortar etc.
Composition silicate (or rare earth is compound) thermal insulation mortar coefficient of thermal conductivity is big, is 0.065W/mk.Reach the thickness that satisfactory heat insulation effect has only increases insulation layer, but the thermal insulation mortar adhesion strength is relatively low, thickness is excessive to come off easily or crackle occurs, construction inconvenience in addition, and surface irregularity influences attractive in appearance.
The shortcoming of expanded polystyrene plate (EPS plate) is to be unable to undergo collision, in case breakage can't be repaired, changes very difficultly again, can stay infiltration hidden danger, and the easy pulverizing problem of polystyrene material itself may cause the decline of energy-saving effect.
In addition, polyurethane material belongs to combustible material, its oxygen index (OI) has only 18, far below airborne averaged oxygen content (22), also can send a large amount of dense smoke and some toxic and harmfuls during unmodified polyurethane foam combustion, therefore as seen, unmodified polyurethane foam brings great hidden danger can for undoubtedly the people's lives and property safety as wall heat insulation material.
Summary of the invention
The purpose of this utility model is to solve deficiency and the problem that exists in the above-mentioned present technology, and a kind of flame-retardant polyurethane warming plate that hard bubbles is provided.
The technical solution of the utility model is as follows:
The flame-retardant polyurethane of the present utility model warming plate that hard bubbles is made up of panel and the flame-retardant polyurethane layer that hard bubbles, and hard bubble layer foaming back and panel on panel of flame-retardant polyurethane links together.
The flame-retardant polyurethane of the present utility model warming plate that hard bubbles, its described panel is the magnesite plate.
The flame-retardant polyurethane of the present utility model warming plate that hard bubbles, its described flame-retardant polyurethane layer that hard bubbles is the hard polyurethane foam of polynary nanometer filler modified synergic.
The flame-retardant polyurethane of the present utility model warming plate that hard bubbles, its described polynary nanometer filler is nanometer Mg (OH)
2, nanometer SiO
2, nanometer Al
2O
3, nano-TiO
2And nanometer CaCO
3In two or more mixture; Described Nano filling is preferably dimensioned to be 5～80nm.
The flame-retardant polyurethane of the present utility model warming plate that hard bubbles, its described Nano filling consumption is 1～10% of a hard polyurethane foam weight; Before using, described Nano filling needs with one or more processing in borate, aluminic acid ester, titanate esters or the silane coupler; The processing consumption of described borate, aluminic acid ester, titanate esters or silane coupler is preferably 0.3～3wt% of Nano filling.
The flame-retardant polyurethane warming plate manufacturing process of hard bubbling is: with the parallel placement up and down of two blocks of magnesite plates, certain clearance is left in the centre, then nanometer particle-modified polyurethane foam combination material is irritated in wherein, the natural foaming moulding, after treating that the foam slaking is stable, promptly get the required flame-retardant polyurethane warming plate that hard bubbles along the cutting of foam center line with cutting machine.
Magnesite flaggy surface can have painted, and warming plate when construction is laminated facing to metope with hard polyurethane foam, adopt special-purpose bonding agent with this face stick on exterior wall or (with) on the metope of interior wall, realize wall self-insulation.
Compared with prior art the beneficial effects of the utility model are:
The flame-retardant polyurethane of the present utility model warming plate fire resistance excellence of hard bubbling, heat-insulating property is superior, and the compressive strength height is easy to maintenance, and not pulverizable.
Hard polyurethane foam is a kind of low-density microcellular foam with hole-closing structure, it is as the insulation main body of this warming plate, coefficient of thermal conductivity is little, this material has that light weight, specific strength are big, heat insulation, sound insulation, damp proof insulation, corrosion resistant are burnt, not pulverizable, structural stability waits premium properties by force, also has the performance of good agglomerability and easy cutting processing simultaneously.
The nano material modified synergic can improve the fire resistance and the intensity of hard polyurethane foam.In addition, the magnesite plate has certain intensity and excellent fire resistant flame retardant performance, can improve the surface strength and the fire resistance of warming plate as panel with it.
This warming plate can be made into the sheet material of certain specification, and as required size cutting during use also can directly be made brick type or other moulding.Wherein the thickness of rigid polyurethane alveolar layer can specifically be incubated according to building and require to design.
In sum, the utility model warming plate is used for the inside and outside body of wall insulation of building, and its performance is better than expanded polystyrene plate (EPS plate) and general thermal insulation mortar, can satisfy weight reduction, reduce cost, the energy-saving and cost-reducing needs, and cutting is convenient, is easy to cut stickup, and construction is simple, painted convenience, specious, long service life especially is suitable as external-wall heat-insulation material.

Fig. 1 is a structural representation of the present utility model
The specific embodiment
As shown in Figure 1, the flame-retardant polyurethane of the present utility model warming plate that hard bubbles is made up of panel 1 and the flame-retardant polyurethane layer 2 that hard bubbles.
This plate manufacturing process is: with the parallel placement up and down of two blocks of magnesite plates, the high gap of 10cm is left in the centre, then with 1wt% nanometer Mg (OH)
2, 1wt% nanometer SiO
2And 1wt% nanometer Al
2O
3The polyurethane foam of modification combination material is irritated in wherein, and natural foaming was treated the foam slaking after 24 hours, adopts cutting machine to cut along foam center line (promptly apart from the inboard 5cm of magnesite plate place) and promptly gets the required flame-retardant polyurethane warming plate that hard bubbles.Material property sees Table 1.
During the construction of this warming plate, body of wall, stick on surface of wall from bottom to top by row, after stickup finishes, should carry out the plate seam immediately and handle with the special bonding agent with the hard polyurethane foam course.Earlier with supporting pot type polyurethane foam material perfusion to being shallower than warming plate surface 6-8mm, extremely put down with the cement paste jointing again or be circular-arc with external surface.
