Background technology
In the domestic and international existing insulation and decoration system product wall surface spraying thermal insulation coatings is outside arranged directly at present, but its facing is many based on elastic heat preserving coating, ornamental surface heat insulation effect and durability are relatively poor.And in-situ spraying polyurethane foam system, technical requirements is very professional, smears complicated procedures of forming such as facing mortar, spray paint again.Also there are similar poor durability, construction quality to be difficult to drawbacks such as control.
Domestic and international in addition existing self-insulation system all be with gas concrete or building block as heat insulating material because gas concrete or building block water absorption are big, suction back heat insulation effect is undesirable.
Adopt polymer cement to paste the XPS extruded sheet as existing heat-insulation system more, reinforce with the riveting bolt, glass fabric turns over bag, polymer cover rubber cement is wiped one's face, sticking brick or smear the putty swabbing then, its working procedure complexity, consumption worker feed consumption, long construction period, insulation and decoration cost height, workmanship are not easy to guarantee.If paste stone material, stone material is thick, and then weight is big, and system bears incessantly.And the thick easy hollowing of thin stone material site operation of stickup 5-8mm, stone material breakage rate height.Adopt aluminium-plastic panel facing planeness crack to be difficult to control.If the straight aluminium template facing valency height that pastes, not environmental protection bonds.Cladding aluminium-plastic panel facing has destroyed the globality of heat-insulation system again.
And the expansion polyphenyl plate steel-wire-net reinforced concrete that adopts waters system earlier, still will consider the decoration problem at last.The associated materials heat-insulation system is also in the experimental stage.
The composite insulation boards of some producer's exploitation generally all is to adopt epoxy glue (or the pure organic gel of unsaturated-resin) to carry out insulation layer and cement board (or metal sheet) bonding compound, though it is bonding at that time very firm, but pure organic gel exists freeze-thawing resistant and ultraviolet-resistant aging, the very poor shortcoming of durability, summer through daylighting hyperthermia be exposed to the sun, the freeze thawing in winter, easy layering of long duration comes off, it is overweight to add unit area, is applied in to have very big potential safety hazard on the exterior wall.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of heat-insulating decorative composite board, to solve the existing existing many weak points of exterior wall heat-preserving system.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
Heat-insulating decorative composite board is made of finish coat, insulation layer and enhancing bonding protection bottom, it is characterized in that, sets up an enhancing tack coat that is made of glass grid and epoxy cement-based adhesive between described finish coat and insulation layer.
In the utility model, described enhancing bonding protection bottom also is made of glass grid and epoxy cement-based adhesive.
In the utility model, between enhancing tack coat and insulation layer, be embedded with to the outstanding suspension member of heat-insulating decorative composite board outer rim.The preburying part branch of described suspension member offers is convenient to the aperture that epoxy cement-based adhesive infiltrates, and offers hanging hole at the exposed parts of suspension member.
In the utility model, described finish coat is lithotome layer or natural inorganic sliver or ceramic tile layer or glassy layer or dope layer or fluorine carbon enamelled coating or sheet-metal layers or plastic-aluminum flaggy.
Described insulation layer is XPS extruded sheet or polyurethane foam board or EPS plate or inorganic material warming plate.
Owing to adopt technical scheme as above, the utility model employing epoxy cement-based adhesive is handled the bonding between each layer, has increased adhesion strength, and durability is long, and coating is thin.Adopt fiberglass gridding cloth, improved cracking resistance and increased the anti-crawl agentdefiection degree, play waterproof, protection against the tide, anti-cold alkali effect again.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with specific embodiments and the drawings, further set forth the utility model.
Referring to Fig. 1 and Fig. 2, heat-insulating decorative composite board by finish coat 1, insulation layer 3 with strengthen bonding protection bottom 4 and constitute, is set up an enhancing tack coat 2 that is made of glass grid and epoxy cement-based adhesive between finish coat 1 and insulation layer 3.Strengthening bonding protection bottom 4 also is made of glass grid and epoxy cement-based adhesive.
For convenience heat-insulating decorative composite board is hung on the exterior wall, between enhancing tack coat 2 and insulation layer 3, be embedded with to the outstanding suspension member 5 of heat-insulating decorative composite board outer rim.Suspension member 5 is into the bending member of stairstepping, is divided into pre-buried part 51 and exposed parts 52.Offer the aperture 511 of being convenient to the epoxy cement-based adhesive infiltration in pre-buried part 51, and offer hanging hole 521 at exposed parts 52.
Embodiment 1
