The construction conditions require that the ground can not have open water, the water content of the concrete is less than 8 percent, and the construction difficulty is high in a humid environment; the flatness of the ground base layer requires that the error in two meters is less than or equal to 3mm, the error of the whole ground is +/-5 mm, the interval of each process of primer coating, intermediate coating and top coating is 24 hours, the top coating can be used after finishing the construction for 72 hours, and the construction period is long.
Because the concrete has the characteristics of poor corrosion resistance to acid, alkali, salt and oil, low water absorption rate, poor impermeability, friction with hard objects, easy scratch, influence on aesthetic property, poor hardness and the like, the traditional method for automatically leveling the ground is difficult to meet the design and use requirements, the construction content of the epoxy ground is not easy to complete, and the epoxy coating is easy to damage after construction, cannot meet the use requirements and causes rework; the method specifically comprises the following steps:
1) the concrete sealing and curing agent coating is formed by integrating a concrete sealing and curing agent which permeates into a concrete base layer; the epoxy middle coating roller coating and the epoxy top coating roller coating are epoxy paint layers, and the epoxy bottom coating batch coating and the epoxy top coating batch coating are mixtures of epoxy paint, epoxy paint curing agents and additives; the additive is epoxy mortar and quartz sand; the epoxy paint of the epoxy base coating batch coating and the epoxy intermediate coating roller coating is epoxy mortar floor paint; the epoxy paint of the epoxy top coating and the epoxy top roller coating is epoxy self-leveling floor paint; the sum of the thicknesses of the epoxy primary coating batch coating, the epoxy intermediate coating roller coating, the epoxy surface coating batch coating and the epoxy surface coating roller coating is not less than 5 mm.
2) After the base layer is treated, the traditional sealing primer treatment is optimized and changed into a concrete sealing curing agent, so that the sealing primer penetrates into the concrete base layer and is combined with the concrete base layer into a whole, the impermeability of the sealing primer is improved, the influence of the construction environment on the operation is reduced, and the sealing primer can be constructed in a humid environment.
3) Before the epoxy base coat construction, quartz sand is added into the epoxy floor paint to form a slightly rough base surface, so that the base paint is not allowed to form a film too smooth, and the formed film is in a mottled shape, thereby being more beneficial to the adhesion of epoxy mortar.
4) In the construction of the epoxy middle coating and the epoxy top coating, quartz sand, quartz powder, an epoxy paint curing agent and the like are added, so that the drying time of each operation surface is only 7 hours, the process interval time is shorter, and the corrosion resistance, the hardness and the like of the terrace are higher;
the disadvantages are as follows: (1) the manufacturing cost is slightly higher than that of the traditional construction; (2) the construction process has higher requirements, each procedure needs continuous construction, so that pollution is avoided, and the surface layer is easy to crack and fall off; (3) the high temperature resistance is poor, and aging is accelerated and the strength is lowered when the alloy is in a high temperature environment for a long time.
