Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
The patch stone of the embodiment of the present invention, as shown in Figure 1, comprises insulating board 1, and insulating board 1 has relative first surface and second, and first surface is coated with the first boundary layer 2 and texture coating 3 successively; Second face is coated with second interface layer 4, elastic coating 5, stone-imitative layer 6 and topping 7 successively; First boundary layer 2 is cohesive material with second interface layer 4;
Insulating board 1 adopts silica aerogel to make, and the coefficient of thermal conductivity of this heat insulating material is less than 0.020w/mk (when 25 DEG C);
Cohesive material adopts self-crosslinkable polyurethane acrylic resin modified, cohesive bonding intensity is greater than 1.5MP, possesses high osmosis simultaneously, with basic unit's adhesive power excellence, its effect carries out interface processing to the fiberglass surfacing of insulating board 1, can with elastic coating 5 close attachment;
Texture coating 3, for having the dope layer of rough surface, adopts the dope layer containing quartz sand, because its rough surface is easily pasted, patch stone can be made firmly to be attached on base course wall 8 in the present embodiment;
Elastic coating 5 is the elastic napping coatings made for film forming matter with hud polymerization elastomeric propylene yogurt liquid; Elasticity and water resistance have concurrently, provide background color to stone-imitative layer simultaneously;
Stone-imitative layer 6 is a kind of water-water multicolor finish layers, and be main component by inorganic mineral gel and organosilicon modified crylic acid resin, be deployed into the outward appearance of marble or granite by the colour particles of multiple transparency, effect is true to nature, and weather resistance is good.
Topping 7 is coated with material for aqueous transparent face, by adding nano silicon and micron order synthesis barium sulfate, making product seal protection performance excellent, extending the application life of patch stone.
The thickness of insulating board 1 is 3-20mm, and the thickness of elastic coating 5 is 1mm, and the thickness of stone-imitative layer 6 is 0.1mm, and the thickness of second interface layer 4 is 1mm, and the thickness of topping 7 is 0.1-0.2mm; The thickness of the first boundary layer 2 is 0.5-1mm, and the thickness of texture coating 3 is 2mm.
The present invention also provides the preparation method of patch stone, and as shown in Figure 2, environment temperature during making is more than or equal to 5 DEG C and is less than or equal to 50 DEG C schematic flow sheet, comprises the following steps:
Step S101: with insulating board 1 for basic unit, criticizes at the first surface of insulating board 1 and scrapes the first boundary layer 2;
Step S102: treat the first boundary layer 2 surface drying, the first boundary layer 2 is criticized and scrapes texture coating 3;
Step S103: treat texture coating 3 surface drying, scrapes second interface layer 4 at second of insulating board 1 batch;
Step S104: treat second interface layer 4 surface drying, roller coating elastic coating 5 in second interface layer 4;
Step S105: treat elastic coating 5 surface drying, elastic coating 5 sprays stone-imitative layer 6;
Step S106: treat stone-imitative layer 6 surface drying, roller coating topping 7 on stone-imitative layer 6.
Whole manufacturing process temperature should be more than or equal to 5 DEG C of degree, and should not exceed the maximum temperature 50 DEG C of plant produced, the per pass inter process interval is not limit, surface drying simultaneously, and because season is different, rate of drying is also different.
Product, in the process of transport, should be noted not making package failure, prevents from or horizontal pressure, adds a cover tarpaulin if desired.Storage is positioned over ventilations, dry place at once, and storage temperature should higher than 40 DEG C, and storage height of embankment should not exceed and keeps flat 3 layer coiled material height, stands up individual layer stacking.During stacking, answer the plank that liner is smooth, overhead 20cm, should prevent from drenching with rain, tan by the sun, freezing, forbid contacting with acid, alkali, oils and organic solvent etc., and isolation thermal source, and the pertinent regulations of transportation department should be met.
The present invention also provides the construction method utilizing described patch stone, that is, coated with adhesive 9 in the texture coating 3 of patch stone first surface, and the one side being coated with cementing agent 9 is pasted onto the surface of base course wall 8.
Base course wall 8, refers to major structure of construction, is generally concrete.
Cementing agent 9, refers to the material being pasted onto by patch stone and base course wall 8 uses.
The present invention reduces greatly relative to traditional patch stone thickness, alleviates deadweight, but still can obtain good heat insulation effect; Its preparation method and construction method are also comparatively simple.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
