Abstract
A hard foamed polyurethane thermal insulative wall board is used for the thermal insulative material of the building wall body, consisting of a hard foamed polyurethane layer and a polyurethane coating layer in turn, wherein the hard foamed polyurethane layer is used as the main thermal insulative body, and is of less thermal conductivity and better heat insulation effect; a polymer mortar layer can improve the surface strength, a fibrous layer is arranged between two polymer mortar layers, to increase tenacity and strength of the plate material. The thermal insulative wall board has the good performances of light weight, high specific strength, thermal insulation, sound insulation, dampness insulation, strong structural stability, and convenient cutting, etc. The utility model is pasted on the wall surface by special sticking agent with convenient process.
Description
(technical field)
The utility model is about a kind of hard polyurethane foam wall insulated board, is the heat-barrier material that is used for the building masonry wall insulation.
(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 expansion polyphenyl 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 expansion polyphenyl 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.
(summary of the invention)
In order to solve the above-mentioned shortcoming that existing wall heat insulation material exists, the utility model provides that a kind of heat-insulating property is superior, compressive strength is high, the hard polyurethane foam wall insulated board of easy to maintenance, not pulverizable.
The utility model hard polyurethane foam wall insulated board is to be composited by rigid polyurethane alveolar layer and polyurethane coating layer.The rigid polyurethane alveolar layer can be added with fire retardant.
In addition, the utility model warming plate also can comprise following various technical scheme:
Warming plate is composited by rigid polyurethane alveolar layer, polymer mortar layer and polyurethane coating layer successively;
Warming plate is composited by hard bubble layer, polymer mortar layer, fibrage, polymer mortar layer and polyurethane coating layer of ammonia ester successively.
Said fibrage can be macromolecule grid cloth or glass fiber, also other fibrous material.The polymer mortar laminar surface can have painted.
In this 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.
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.Polymer mortar layer is the mixture of cement, fine sand and the polymer bonding agent of certain proportioning, it solidifies the back and is bonded to one with rigid polyurethane alveolar layer and fibrage, this layer effect mainly is the appearance intensity that increases warming plate, certain heat insulation effect is also arranged, fibrage is added between two polymer mortar layers, and its effect is toughness and the intensity that increases sheet material; Polyurethane coating is the external surface topping of this warming plate, makes any surface finish attractive in appearance and be convenient to painted.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 expansion polyphenyl 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.
(description of drawings)
Fig. 1, Fig. 2, Fig. 3 are respectively three kinds of section structure schematic diagrames of the utility model wall insulated board.
(specific embodiment)
Fig. 1 embodiment represents to be total to the two-layer warming plate section structure of forming by rigid polyurethane alveolar layer 1 and polyurethane coating layer 2.
Fig. 2 embodiment represent by rigid polyurethane alveolar layer 1, polymer mortar layer 3 and polyurethane coating layer 2 totally three layers of warming plate of forming protect section structures.
Fig. 3 embodiment represent by rigid polyurethane alveolar layer 1, polymer mortar layer 3 ', fibrage 4, polymer mortar layer 3 and polyurethane coating layer 2 totally five layers of warming plate section structure of forming.
Fibrage 4 can be the PVC grid cloth, also can be glass fabric or other cloth.
(specific embodiment)
Be that example illustrates that this plate manufacturing process is below with Fig. 3: make certain thickness hard polyurethane foam plate 1, cement, fine sand and the polymer bonding agent of certain proportioning are smeared above it (be polymer mortar 3 ') with certain thickness, multiple on it with PVC grid cloth 4, smear one layer of polymeric mortar 3 subsequently again, floating, dry and hard back is coated with polyurethane coating layer 2 on polymer mortar 3.
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.
