Compared with prior art, technical scheme of the present invention has the following advantages: it reduces greatly with respect to traditional patch stone thickness, has alleviated deadweight, but still can obtain preferably heat insulation effect; Preparation method and job practices are also comparatively simple.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
The patch stone of the embodiment of the 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; The second face is coated with second contact surface layer 4, elastic coating 5, stone-imitative layer 6 and topping 7 successively; The first boundary layer 2 is cohesive material with second contact surface 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 (25 ℃ time);
Cohesive material adopts self-crosslinkable polyurethane acrylic resin modified, cohesive bonding intensity possesses high osmosis simultaneously greater than 1.5MP, with basic unit's adhesive power excellence, its effect is that the fiberglass surfacing to insulating board 1 carries out interface processing, can with elastic coating 5 close attachment;
Texture coating 3 adopts the dope layer that contains quartz sand for having the dope layer of rough surface in the present embodiment, because its rough surface is pasted easily, patch stone firmly is attached on the base course wall 8;
Elastic coating 5 is elastic napping coatings of making as film forming matter take 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 bag water multicolor finish layers, is main component by inorganic mineral gel and organosilicon modified crylic acid resin, is deployed into the outward appearance of marble or granite by the colour particles of multiple transparency, and effect is true to nature, and weather resistance is good.
Topping 7 is coated with material for the aqueous transparent face, by adding the synthetic barium sulfate of nano silicon and micron order, makes product seal protection performance excellent, prolongs 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 contact surface 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, schematic flow sheet as shown in Figure 2, the environment temperature during making may further comprise the steps more than or equal to 5 ℃ and less than or equal to 50 ℃:
Step S101: take insulating board 1 as basic unit, criticize at the first surface of insulating board 1 and to scrape the first boundary layer 2;
Step S102: treat the first boundary layer 2 surface dryings, scrape texture coating 32 batches of the first boundary layers;
Step S103: treat texture coating 3 surface dryings, scrape second contact surface layer 4 at second of insulating board 1 crowd;
Step S104: treat second contact surface layer 4 surface drying, roller coating elastic coating 5 on second contact surface layer 4;
Step S105: treat elastic coating 5 surface dryings, at elastic coating 5 spraying stone-imitative layers 6;
Step S106: treat stone-imitative layer 6 surface dryings, roller coating topping 7 on stone-imitative layer 6.
Whole manufacturing process temperature should be more than or equal to 5 ℃ of degree, should not surpass simultaneously 50 ℃ of the maximum temperatures of plant produced, and the per pass inter process interval is not limit, and surface drying get final product, because season is different, rate of drying is difference also.
Product should be noted not making package failure in the process of transportation, prevents from or horizontal pressure, adds a cover in case of necessity tarpaulin.Store and at once be positioned over ventilation, dry place, storage temperature should not be higher than 40 ℃, stores height of embankment and should above keep flat 3 layer coiled material height, not stand up individual layer and stack.During stacking, answer the smooth plank of liner, 20cm overhead should prevent from drenching with rain, tans by the sun, freezing, forbids contacting with acid, alkali, oils and organic solvent etc., and the isolation thermal source, and should meet the pertinent regulations of transportation department.
The present invention also provides the job practices of utilizing described patch stone, that is, and and coated with adhesive 9 on the texture coating 3 of patch stone first surface, and the one side that will be coated with cementing agent 9 sticks on 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 patch stone is sticked on employed material on the base course wall 8.
The present invention reduces greatly with respect to traditional patch stone thickness, has alleviated deadweight, but still can obtain preferably heat insulation effect; Its preparation method and job practices are also comparatively simple.
The above only is preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away 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.
