Description
Technical Field
The invention relates to the technical field of architectural decoration construction, in particular to an acrylic crystal resin simulated water surface construction method.
Background
The water scenery decoration, which is made of water and reappears naturally, can be combined with buildings, sculptures, plants or other artworks to create unique style decoration effect, and is an important architectural landscape decoration method, such as museums, exhibition halls and the like, which often adopts real water to make scenery.
The waterscape design by adopting real water is easy to breed microorganisms and generate peculiar smell in the water body along with the increase of time, and the maintenance cost is high; meanwhile, the real water body can also influence the environmental humidity of museums and exhibition halls, and is not beneficial to the protection of cultural relics and exhibits. Thus, a simulated waterscape using a transparent resin has been produced.
At present, the most widely applied resin in the architectural decoration field is epoxy resin, and for example, a Chinese patent with an authorization publication number of CN104533053B discloses an epoxy floor construction method, which comprises the following steps: (1) polishing and cleaning the ground, brushing an epoxy primer, and uniformly scattering No. 9 quartz sand before the epoxy primer is not cured; (2) after the primer is cured, cleaning the redundant No. 9 quartz sand, and maintaining for 10-12 h; (3) preparing a high-power sand floating material, uniformly spreading the high-power sand floating material on the ground, and then compacting and leveling the high-power sand floating material by using a troweling machine; (4) and after the high-power sand intermediate coating material is fully cured, spraying epoxy floor paint on the surface layer. It builds the decorative effect similar to the water surface on the ground through epoxy.
Due to the nature of the epoxy resin, the epoxy resin has large heat release during curing, is easy to retract and crack during large-area and high-thickness construction, and is difficult to obtain expected high transparency, three-dimensional perspective and mirror decoration effects. The acrylic resin has high transparency and light weight, and is an ideal material for carrying out high-simulation water surface construction.
However, the acrylic resin is rarely used for large-area and high-thickness architectural decoration construction in the prior art, and cannot meet the market demand. Therefore, the invention provides the acrylic crystal resin simulated water surface construction method which can obtain high transparency, three-dimensional perspective and high simulation degree with good mirror effect.

step one, base surface cleaning: cleaning up floating dust and old coatings of a construction base surface, and then making a cement base layer;
step two, cement self-leveling construction: performing cement self-leveling on the surface of the cement base layer, and drying to form a self-leveling layer;
step three, colored drawing: performing waterscape painting on the surface of the self-leveling layer by using a propylene pigment;
step four, preparing acrylic resin: the acrylic resin is acrylic resin AB glue, which comprises a component A and a component B; mixing the component A and the component B according to a designed proportion, uniformly stirring along the same direction until no water wave and thread appear, standing, and automatically defoaming to obtain transparent acrylic resin;
step five, pouring: uniformly pouring the acrylic resin prepared in the fourth step on the surface of the self-leveling layer treated in the third step, and blade-coating and leveling;
step six, defoaming and maintaining: eliminating bubbles on the surface layer of the poured acrylic resin by using a defoaming roller, and maintaining until the acrylic resin is completely cured;
and step seven, repeating the step four to the step six for multiple times until the thickness of the cured acrylic resin layer reaches the design thickness, and finishing the acrylic resin simulation water surface construction.
By adopting the technical scheme, the method at least has the following effects: 1. the cement base layer and the cement are sequentially prepared and then the acrylic resin construction is carried out, so that on one hand, the construction base layer is flat and smooth, and on the other hand, the invention has the advantages of reducing the water seepage of the base layer and reducing the possibility of prolonging the curing time, bulging and foaming caused by the contact with water before the acrylic resin is cured; 2. the simulated water surface constructed according to the specific process steps of the invention has high transparency, three-dimensional perspective and mirror decoration effects and extremely high simulation degree; 3. compared with an epoxy floor, the acrylic crystal resin simulated water surface constructed by the method is not easy to crack and retract, can be constructed in a large area and a high thickness, and does not have the problems of easy generation of peculiar smell, influence on environment humidity and the like; 4. the water scene painting which adopts the acrylic crystal resin with high transparency to match with the acrylic pigment has excellent decorative effect and strong artistic expressive force; 5. the construction method can be carried out in a local area, and can be normally constructed under the condition that museums and exhibition halls are not closed.
Further, in the fifth step, the casting thickness of the acrylic resin is less than or equal to 2 cm.
By adopting the technical scheme, the thickness of the acrylic resin poured on each layer is not more than 2cm, the problems of retraction, cracking, bubbles and the like generated in the resin curing process can be reduced to the maximum extent, the total thickness is finally ensured to reach the design thickness by multi-layer construction, and the simulated water surface with high transparency, three-dimensional perspective and excellent mirror surface decoration effect can be obtained.
And further, in the seventh step, before the acrylic resin is poured each time, performing dust collection treatment on the surface of the acrylic resin layer in the previous pouring construction.
By adopting the technical scheme, perfect fusion between the acrylic resin poured on each layer and the resin solidified on the previous layer is ensured, and the problems of layering, air bubbles and the like are not easy to occur.
Further, in the fifth step, the cast acrylic resin is coated, scraped and leveled, and maintained for 72 hours, and then the next step of construction is carried out.
By adopting the technical scheme, the influence of external factors on resin curing is reduced to the maximum extent, the resin can be perfectly fused with the previous layer of resin when the next layer of resin is poured, and the problems of cracking, layering, air bubbles and the like are not easy to occur.
Furthermore, in the fifth step, when the acrylic resin is cast, no other construction cross operation is performed.
By adopting the technical scheme, the influence of dust and the like on resin curing caused by other construction is reduced, and the cured resin is transparent and free of impurities.
And further, when the fifth construction is carried out, controlling the relative humidity of the construction site to be less than or equal to 85 percent.
Through adopting above-mentioned technical scheme, acrylic resin has the hygroscopicity, and the resin top layer can form the water film when ambient humidity is greater than 85%, influences the solidification of top layer resin, when carrying out next layer resin pouring construction, is difficult to guarantee its fusibility with previous layer resin, the layering fracture scheduling problem easily appears.
Further, in the step one, after the cement base layer is made, whether the cement base layer has cracks or vacant shells is checked; if so, deep cutting and cleaning are carried out, and then epoxy resin mortar is used for filling.
By adopting the technical scheme, on one hand, the subsequent cement self-leveling construction can have a good leveling effect; on the other hand, the deterioration of the water resistance of the base layer caused by cracks, cavities and the like is reduced, so that the subsequent construction of the resin layer is not influenced by moisture absorption easily.
Further, before the second step, polishing the cement base layer by using a polishing machine, and then washing by using water; and (5) after drying, completely sucking the loose particles on the surface by using a dust collector, measuring the water content, confirming the drying, and then performing construction in the second step.
By adopting the technical scheme, the surface of the cement base layer is flat and dry, a flat and smooth base surface can be obtained after the cement self-leveling construction is carried out, and the subsequent propylene pigment waterscape painting is facilitated.
Further, in the fourth step, the mass ratio of the component A to the component B is 1: 1.5-2.5.
By adopting the technical scheme, the curing time of the acrylic resin with the proportion is shorter after construction, and the high-transparency and impurity-free transparent resin layer is favorably obtained. The acrylic resin AB glue can be prepared by itself, and can also be acrylic resin AB glue sold in the market, such as Yakeli crystal resin purchased from Shanghai Chengni environmental Art Co.
Further, the component A of the acrylic resin AB glue in the fourth step comprises,
methyl methacrylate 85%
1.8 percent of initiator
13.2 percent of polymerization inhibitor,
the component B comprises a component A and a component B,
99 percent of methyl methacrylate
1% of accelerator.
By adopting the technical scheme, the initiator does not cause the bulk polymerization of the methyl methacrylate in the component A due to the existence of the polymerization inhibitor. After the component A and the component B are mixed according to a certain proportion, the polymerization inhibition of the polymerization inhibitor fails due to the existence of the accelerator, and the initiator initiates the methyl methacrylate to generate bulk polymerization to form the cured and transparent acrylic resin. The shrinkage rate of the resin with the specific proportion is as low as 3 per thousand during curing, the resin is not easy to crack, and the resin is suitable for pouring large-area and high-thickness resin.
In conclusion, the invention has the following beneficial effects:
1. the cement base layer and the cement are sequentially prepared and then the acrylic resin construction is carried out, so that on one hand, the construction base layer is flat and smooth, and on the other hand, the invention has the advantages of reducing the water seepage of the base layer and reducing the possibility of prolonging the curing time, bulging and foaming caused by the contact with water before the acrylic resin is cured;
