Description

Technical Field

[0002] In the entire concrete project, concrete maintenance is the sub-project that takes the longest time and has the greatest impact on concrete quality. The slab structure concrete can be maintained by secondary plastering, water storage, covering and other methods, but the maintenance of the facade structure concrete has always been a difficult problem to solve in the field of concrete engineering. In the actual production of the current project, the facade structure concrete is basically maintained by direct sprinkling or hanging geotextile thick sprinkling.

In actual use, a plurality of adhesive Velcro strips are pasted on the moisturizing layer on the inner side of the curing cloth. After the large-facade concrete formwork is removed, water is quickly sprinkled to wet the moisturizing layer of the curing cloth, the adhesive protective film on the inner side of the adhesive Velcro strips is torn off, and the curing cloth is evenly pasted on the concrete surface. After the curing cycle is over, the curing cloth is torn off along the adhesive Velcro strips pasting direction.

It is easy to operate and highly safe.

[0025] In some preferred embodiments, the first adhesive piece 7 is arranged at the edge of the outer short side of the windproof protective layer 1, and the second adhesive piece 8 is arranged at the outermost edge of the outer short side of the windproof protective layer 1 and away from the first adhesive piece 7, so that the first adhesive piece 7 and the second adhesive piece 8 are respectively arranged on the inner and outer sides of the two relative short sides of the curing film, so that the two curing films can be overlapped and pasted together in actual use.

[0027] In some embodiments, the distances between the through holes 6 are equal, and the interval between two adjacent through holes 6 is 1 m. Specifically, there are a plurality of through holes 6, which are arranged in sequence along the short side or long side direction of the windproof protective layer, adhesive layer, thermal insulation layer, water absorption and moisturizing layer and veneer moisturizing layer, and the through hole 1 is set to be circular to facilitate the hanging of the curing film, and hollow rivets are also installed in the circular through hole 6 to enhance the bearing capacity of the circular through hole 6 and prevent the curing film from being torn by external force.

[0028] In some embodiments, the windproof protective layer 1 is a PE film or a PVC coated textile fabric with a thickness of 0.2 to 0.3 mm, which plays a windproof protection role, and its color can be customized and adjusted according to actual conditions.

[0029] In some embodiments, the adhesive layer 2 is EVA hot melt adhesive or TPR hot melt adhesive, with a softening point higher than 80°C and a melting point lower than 160°C.

[0030] In some embodiments, the thermal insulation layer 3 is a lightweight thermal insulation sheet such as EPE pearl cotton, bubble film or aluminum foil bubble film, and has a thickness of 2 to 5 mm.

It has good water retention capacity, and does not need to be frequently sprinkled with water for moisturizing in actual use, and can achieve long-term moisturizing.

[0032] In some embodiments, the surface moisturizing layer 5 is a polyester non-woven fabric or a geotextile with a thickness of 0.2 to 0.5 mm, so that the water in the curing film is promptly transferred to the surface of the concrete to be cured to keep the concrete surface moist.

[0033] In this example, the production process of the curing film includes the following steps:

[0034] S1. Mechanically flatten the modified fiber mesh cloth, use a funnel to evenly add polymer water-absorbing resin SAP particles to the first layer of modified fiber mesh cloth, cover the surface of the SAP particles with modified fiber mesh cloth for hot rolling reinforcement, and use polished steel rollers and point bonding to integrate the upper and lower pressing rollers to obtain a water-absorbing and moisturizing layer 4.

[0035] S2, the thermal insulation layer 3, the water-absorbing and moisturizing layer 4 and the veneer moisturizing layer 5 are mechanically leveled and laid in sequence, and then formed in one step by a needle punching machine through a needle punching process.

[0036] S3, mechanically level the semi-finished product obtained in S2, spray the hot melt adhesive evenly on the semi-finished product's insulation layer 3, firmly adhere the semi-finished product's insulation layer 3 and the windproof protective layer 1 together through the hot melt adhesive, and finally hot-press them into one to obtain a curing film.

Then immediately hang the curing film of this example on the concrete surface. The overlapping parts of the two curing films are firmly adhered with adhesive tape. After the concrete curing is completed, remove the curing film for next use.

[0039] The utility model arranges a heat-insulating layer 3, a water-absorbing and moisturizing layer 4 and a veneer moisturizing layer 5 which are sewn together by sewing thread, so that the layers are more firmly bonded to improve the durability of the curing film. At the same time, the three-dimensional space formed by the needle-punching process can firmly and evenly fix the polymer water-absorbing resin SAP particles to prevent their movement and agglomeration, thereby improving the durability of the curing film and making the curing film reusable.

[0040] The utility model has a windproof protective layer 1 which is adhered to the heat-insulating layer 3 through an adhesive layer 2, which effectively blocks the pinholes left by the needle puncture method, making the curing film large-surface airtight and effectively preventing the loss of water inside the curing film.

[0041] The utility model has a through hole 6, a first adhesive piece 7 and a second adhesive piece 8. The through hole 6 is convenient for hanging and installing the curing film. The first adhesive piece 7 and the second adhesive piece 8 are convenient for sequentially pasting and connecting a plurality of curing films.
