Abstract
The invention provides a polyurethane building outer layer insulating brick and a method for manufacturing the same. The insulating brick comprises a brick body and an outer decorative layer, wherein the brick body is made from a rigid polyurethane foamed material; and the outer decorative layer is adhered to one side of the brick body through an adhesive. The method comprises the following stepsthat: the outer decorative layer and a polyurethane foaming mould are prepared according to specifications; the adhesive is sprayed or coated on the backside of the outer decorative layer; the outer decorative layer is put in a mould cavity of the polyurethane foaming mould, and the mould cavity is sealed; a black rigid polyurethane foaming material and a white rigid polyurethane foaming materialare mixed evenly according to the proportion, and are poured into the mould cavity through a pouring opening of the polyurethane foaming mould; when pouring is finished, the pouring opening is closedimmediately, and the polyurethane foaming mould is heated by means of steam or hot water; and then demoulding is carried out to obtain the insulating brick. The polyurethane building outer layer insulating brick can improve the insulating property of a building and has reliable quality; moreover, the insulating brick has the advantages of energy conservation, consumption reduction, convenient construction and adaptability for use, and the method for manufacturing the insulating brick is simple and scientific.
Description
Technical field
The present invention relates to a kind of preparation method of insulating brick for building, specifically, related to a kind of preparation method of polyurethane construction outer layer insulating brick, belong to building material field.
Background technology
The building exterior wall heat preserving technology is a kind of technology of benefiting the nation and the people that country advocates energetically, and it can be saved energy and reduce the cost, and reduces the waste of the energy; The External Walls Heating Insulation of prior art mainly comprises exterior wall spray coating heat preservation material, exterior wall paste heat-preserving plate etc., the heat insulating material that it adopted also is not quite similar, but these technology or have the unconspicuous problem of heat insulation effect, there is the problem that is pasted not strongly and leans on, be the thickness that has increased exterior wall, cause architectural appearance too fat to move, not attractive in appearance.
Chinese patent application number is " 200710055104.2 ", denomination of invention discloses a kind of insulating brick and preparation method thereof for the patent of invention of " polyurethane exterior wall thermal insulation brick and preparation method thereof ", its relative prior art has heat insulation effect and use value preferably, but in producing and using, be not difficult to find that its making and difficulty of construction are all bigger, and, heat insulation effect is obvious inadequately, and product is comparatively too fat to move, and result of use is desirable not to the utmost.
In order to overcome the above problems, people are seeking a kind of better technical solution always.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, thereby a kind of preparation method of polyurethane construction outer layer insulating brick is provided.
To achieve these goals, the invention provides a kind of preparation method of polyurethane construction outer layer insulating brick, may further comprise the steps:
Step 1, prepare exterior trim layer and polyurethane foam mould by specification;
Step 2, at described exterior trim layer back spraying or coating adhesive;
Step 3, the described exterior trim layer of step 2 face down inserted the mold cavity of described polyurethane foam mould, seal described mold cavity;
Step 4, black material of hard polyurethane foam and the white material of hard polyurethane foam are mixed in proportion, then, in described mold cavity, pour into a mould by the sprue gate of described polyurethane foam mould;
Step 5, to be cast finishing are sealed described sprue gate immediately, and utilize steam or hot water that described polyurethane foam mould is heated, and heating-up temperature is 60 ℃～85 ℃, and continue heating 4～10 minutes, and then, depanning obtains insulating brick.
Based on above-mentioned, in step 4, the black material of described hard polyurethane foam is 0.5～1: 1 with the volume ratio of the white material of described hard polyurethane foam.
Based on above-mentioned, in step 5, the described insulating brick that obtains placed continued to solidify under the normal temperature 1～2 day.
The relative prior art of the present invention has outstanding substantive distinguishing features and obvious improvement, specifically, the polyurethane construction outer layer insulating brick that adopts this method to make has made full use of hard polyurethane foam material excellent insulating performance, it adopts cementing agent, under special process, will have the exterior trim layer and the ingenious compound one that is of hard polyurethane foam material brick body of good weatherability properties and aesthetic property; With its bonding or be installed in the exterior wall or the roof of building, the building heat preserving effect is improved greatly, have energy-saving and cost-reducing effect, simultaneously, this insulating brick structure design is simple, science, is convenient to produce, and is practical, product is suitable for construction outer layer to be used, and its preparation method is simple, and technology is ingenious, and the foaming of hard polyurethane ester material fully, foaming quality is reliable, and exterior trim layer and hard polyurethane foam material fully can be combined as a whole.
Description of drawings
Fig. 1 is the structural representation of polyurethane construction outer layer insulating brick of the present invention.
The specific embodiment
Below by the drawings and specific embodiments, technical scheme of the present invention is described in further detail.
Embodiment one
As shown in Figure 1, a kind of polyurethane construction outer layer insulating brick comprises brick body 2 and exterior trim layer 1, and described brick body 2 is made by the hard polyurethane foam material, and described exterior trim layer 1 is bonded in described brick body 2 one sides by cementing agent 3.
Described exterior trim layer can be exterior wall ceramics, roof tiles and other building and ornament materials;
The overall dimensions of this insulating brick are with reference to the existing exterior wall ceramics or the specification of furring brick;
The thickness of hard polyurethane foam material brick body can also be decided with reference to " the outer heat insulating work technology guide rule of polyurethane rigid foam exterior wall " according to different regions or customer requirements.
A kind of preparation method of polyurethane construction outer layer insulating brick may further comprise the steps:
Step 1, prepare: the polyurethane foam mould of preparing the exterior trim layer and being complementary by specification with the exterior trim layer;
Step 2, spraying: at described exterior trim layer back spraying or coating adhesive;
Step 3, dress mould: the described exterior trim layer of step 2 face down inserted the mold cavity of described polyurethane foam mould, seal described mold cavity;
Step 4, cast: black material of hard polyurethane foam and the white material of hard polyurethane foam are mixed in proportion, then, in described mold cavity, pour into a mould by the sprue gate of described polyurethane foam mould;
Wherein, the black material of described hard polyurethane foam is 0.8: 1 with the volume ratio of the white material of described hard polyurethane foam;
