Substrate layer is concrete or cement mortar screeding layer;
Moisture-proof barrier adopts the reactive type of coating of one or more layers environment-friendly type---and inorganic scale aqueous epoxide resin paint of the present invention forms; damp-proof coating can with the substrate layer such as concrete, sand-cement slurry mortise; and can continuous seamless film forming; the micro-pore on substrate layer surface is thoroughly sealed; the thoroughly isolated moisture that is derived from external wall and other position; the do not make moist gas cut erosion of protection surface of wall, effect is remarkable.
Ornament layer can select different modes to process:
1, ornament layer is building coating, directly batch Puttying, then priming and finish paint on moisture-proof barrier;
2, ornament layer is wallpaper, as screed-coat polishes flat, and directly brush coating on damp-proof coating, sticking wallpaper;
3, ornament layer is the cladding facings such as wooden boards, glass, ceramic tile, stone material, can carry out to moisture-proof barrier the processing such as mortar protection, only need be to bolt, and steel nail destroys position repairing treatment.
Utilizing inorganic scale aqueous epoxide resin paint of the present invention to carry out protection against the tide to existing interior wall processes:
For not carrying out the moistureproof metope of processing, there is delamination and mouldy in interior wall, at cement basic layer brushing moisture-proof coating of the present invention, more directly smears putty and do coatings decoration layer.
Damp-proof coating can with sand-cement slurry substrate layer mortise, and can continuous seamless film forming, the micro-pore on substrate layer surface is thoroughly sealed, the thoroughly isolated moisture that is derived from external wall and other position, the gas cut erosion of not making moist of protection surface of wall, effect is remarkable.
Application examples two
Inorganic scale aqueous epoxide resin paint of the present invention is also applicable to indoor ceiling smallpox position, carry out protection against the tide and WATER REPELLENT from inside, the top building indoor ceiling ceiling of particularly building, and kitchen and toilet smallpox ceiling etc. easily occurs after the construction site brushing of seepage, can one waterproof and moisture-proof structure be initiatively set from indoor (at the back side of building maintenance structure), prevent that seepage from appearring in smallpox ceiling, avoid reducing because of seepage the work-ing life of facing finishing layer.
Utilize inorganic scale aqueous epoxide resin paint of the present invention; in sand-cement slurry basal plane or the concrete surface brushing of indoor ceiling ceiling; can form at building smallpox ceiling chamber internal surface a kind of protection against the tide and waterproof construction of densification; simple in structure; surface of wall structure is made up of substrate layer, moisture barrier coatings and ornament layer, can protect the brushing of smallpox ceiling to cross the surperficial ornament layer of inorganic scale aqueous epoxide resin paint.
Application examples three
Inorganic scale aqueous epoxide resin paint of the present invention is also applicable to indoor building ground floor to carry out protection against the tide and WATER REPELLENT.Indoor building ground floor is generally normal concrete or sand-cement slurry structure, normal concrete and sand-cement slurry can produce a large amount of holes in condensation cure process, pore size distribution is generally between 20～200nm, and due to the wetting ability that has of Silicon in Cement hydrochlorate, and the reason such as capillarity, so make concrete floor be easy to adsorb various moisture, because the diameter of vapour molecule is only 0.324nm, much smaller than the various spaces of normal concrete self-assembling formation, therefore the concrete synthem of can freely coming in and going out, the steam discharging, make bottom building ground floor easily occur Moisture Regain, affect user's body health.The wood floor decoration layer if user mats formation, the vapour molecule in floor is easy to make the rough ground of direct kiss the earth and timber floor to make moist.
Utilize inorganic scale aqueous epoxide resin paint of the present invention, particularly easily occur after the construction site brushing of seepage in bottom building and timber floor, form a kind of moisture-proof construction of densification, form one waterproof and moisture-proof structure, avoid occurring seepage and moist puzzlement in the future.Then, can directly lay timber floor in the above, or cement levelling or laying floor tile.The anti-surface of terrace tide structure, simple in structure, formed by substrate layer, moisture barrier coatings and ornament layer.
Compliance test result test
Inorganic scale aqueous epoxide resin paint of the present invention, its back side protection against the tide and waterproof effect test that forms coating adopts self-control trial model, as shown in Figure 2, trial model M adopts at present general aerocrete block partition building block to make, be of a size of: 100 × 250 × 600 (mm), dig out a catch basin M1 in concrete middle part.
Brush at twice any one the inorganic scale aqueous epoxide resin paint in above embodiment of the present invention on the surface of the bottom surface 5 of trial model and the surface of two sides 1 and side 2, after brushing first pass, must wait it to parch, then carry out second brushing.After second time curing of coating is dry, the surface that is chosen in wider side 1 is criticized and is scraped one inner wall putty, one seal coat and twice common interiro wall latex paint finish paint.
Criticize the common interiro wall latex paint finish paint of scraping one inner wall putty, one seal coat and twice prior art on the surface of side 3.4 of sides are left intact.We simulate the situation that body of wall is soaked in water, and water filling in catch basin M1, then observes.
Because air-entrained concrete building block is silicate cement foaming structure, material is loose, and water-absorbent is strong.After middle catch basin M1 water filling, water level declines very fast.Duration of test is in order to keep the static hydraulic pressure in inside of masonry, once find that water level reduction will add water to the inside more in right amount.
Test result is as shown in the table:
As can be seen from the above table, the side 1, side 2 and the bottom surface 5 that are provided with the coating that the inorganic scale aqueous epoxide resin paint of the embodiment of the present invention forms have long waterproof infiltration and moisture effect.
Below be only the preferred embodiment of the present invention, it should be pointed out that above-mentioned preferred implementation should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with claim limited range.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
