Abstract
The utility model provides a concrete moisture preserving and heat accumulation maintenance membrane, which belongs to the technical field of building engineering and solves the problems that in the prior art, the work procedures of the maintenance membrane are complicated, and in addition, the cost is higher. The maintenance membrane comprises a macromolecule membrane layer, wherein a first region and a second region are divided on one surface of the macromolecule membrane layer, a two-sided adhesive tape is bonded in the edge direction in the first region, a bonding glue layer and a high-power water absorbing resin layer are respectively arranged in the second region from bottom to top, and the macromolecule membrane layer and the high-power water absorbing resin layer are bonded into a whole through the bonding glue layer. The maintenance membrane has the advantages that the two-sided adhesive tape is bonded in the first region of the macromolecule membrane layer, and the adjacent maintenance membranes are bonded through the two-sided adhesive tape, so the operation is simple, and economy and practicability are realized.
Description
Technical field
The utility model relates to construction engineering technical field, is specifically related to a kind of concrete moisture retention regenerative conservation film.
Background technology
The high performance concrete that low water binder ratio, large volume mineral admixture (as flyash, slag powders) be feature of take is in recent years used widely in all kinds of civil engineerings.From laboratory experiment result, such concrete long-term behaviour will be much better than normal concrete in the past, but in concrete engineering, found, such as the phenomenon of cracking, the too early corrosion of reinforcing bar, to trace it to its cause, found to occur that the concrete of cracking is not obtain effective maintenance mostly.The ratio that flyash participates in hydration reaction is in early days very low, and that slag powders itself will cause shrinking is bigger than normal, this just makes to mix the concrete of flyash, slag powders more needs good maintenance than conventional concrete, and especially the moisturizing steam curing conservation of juvenile stage is most important.
Woven straw, geotechnique are weaved cotton cloth, conventional plastic sheeting for remaining of generally adopting at present, for example: CN203045960U discloses a kind of concrete curing device, it comprises superficial layer, water accepting layer and protective layer, protective layer is exactly that the geotechnique who adopts weaves cotton cloth, woven straw and geotechnique weave cotton cloth needs constantly artificial watering, and most water has been evaporated, both caused the waste of resource also to take certain manpower; Then conventional plastic sheeting often first watering covers plastic sheeting on it, although plastic sheeting has hindered shedding of moisture, but can not guarantee being uniformly distributed of moisture, works end face and facade that especially horizontal wall inscription is larger, and moisture can collect to lower.
On market, occurred in recent years that a kind of inside was stained with the curing film of high power water-absorbing resin particle, at works end face, wipe one's face or facade covers after surface watering after tearing film open, but, the particle size of high power water-absorbing resin is bigger than normal, limited by cost, in unit are, the amount of the resin particle of spreading is little, although can keep for concrete curing water demand, moisture distribution is not still very even., need by pressing an emery stick between adjacent two width curing films, this has increased again the operation of spreading sand with cleaning sand meanwhile.Therefore, provide a kind of simple in structure and lower-cost concrete curing film is necessary.
Utility model content
In order to solve above-mentioned problems of the prior art, the utility model proposes a kind of concrete moisture retention regenerative conservation film, this curing film is simple in structure, economical and practical.
Technical solutions of the utility model comprise:
A concrete moisture retention regenerative conservation film, comprises macromolecule membranous layer, and described macromolecule membranous layer is divided into Yi He region, region two, and described region one is positioned at the edge of macromolecule membranous layer one side, is bonded with double-sided tape described region one is interior along edge direction; Described region two is respectively glue line, high power water-absorbing resin layer from bottom to top, and described macromolecule membranous layer and high power water-absorbing resin layer are bonded to one by glue line.
Further, above-mentioned macromolecule membranous layer is polyethylene film, polyvinyl chloride film or polyester film.
Above-mentioned double-sided tape width is between 1～3cm.
The useful technique effect that the utility model brings:
The utility model proposes a kind of concrete moisture retention regenerative conservation film, the approximate moisturizing steam curing conservation that is used for the works such as works end face and facade concrete, cement stabilized macadam base, in the region one of macromolecule membranous layer, be bonded with double-sided tape, between adjacent curing film, by double-sided tape, undertaken bondingly, make it simple to operate, economical and practical.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described in detail:
Fig. 1 is the utility model curing film expanded view;
Fig. 2 is the utility model curing film overlap joint view;
Fig. 3 is that the utility model curing film is packed up figure;
In figure, 1, macromolecule membranous layer, 2, high power water-absorbing resin layer, 3, double-sided tape.
The specific embodiment
As shown in Figure 1, Figure 3, a kind of concrete moisture retention regenerative conservation film, comprise macromolecule membranous layer 1, the utility model macromolecule membranous layer 1 is polyethylene film, polyvinyl chloride film or polyester film, or directly adopt plastic sheeting, it is the edge that is positioned at macromolecule membranous layer 1 one sides that macromolecule membranous layer 1 is divided into Er， region, Yi He region, region one, the area in region one is advisable with sticking two-faced adhesive tape bar 3 completely, and double-sided tape 3 is bonded in region one; Described region two is respectively glue line, high power water-absorbing resin layer 2 from bottom to top, and high power water-absorbing resin layer 2 is Powdered, and its main component is the cross-linked copolymer of acrylamide and acrylic acid potassium, and high power water-absorbing resin layer 2 powder consumption are between 2～4g/m
2, powder particle fineness is 30～100 orders, macromolecule membranous layer 1 and high power water-absorbing resin layer 2 are bonded to one by glue line.
Above-mentioned double-sided tape width is between 1～3cm.
The concrete operation method of the utility model concrete moisture retention regenerative conservation film:
As shown in Figure 2, first in the submarginal side of macromolecule membranous layer 1 (one position, region) along edge direction bonding double-sided tape 3, then in the region of double-sided tape 3 homonymies two position spraying adhesive glue, by high power water-absorbing resin layer 2, evenly stand is full on be sprayed with glue line, guarantee that glue line surface all sticks high power water-absorbing resin layer 2, finally by macromolecule membranous layer 1 rolled for future use.
For works end face, first double-sided tape 3 is sticked to the end face of adjacent macromolecule membranous layer 1, lap width is controlled at 5～10cm, then covers the concrete surface that just spilt water; For works facade, after form removable, this curing film finished product is wound around from bottom to top around works surface in the shape of a spiral, guarantee that double-sided tape 3 can cling adjacent part, then along curing film and works surface gap slow trickle from top to bottom, guarantee that curing film is close to works surface, make the saturated need for concrete curing of high power water-absorbing resin layer 2 water suction.
Should be understood that; those of ordinary skill in the art is under enlightenment of the present utility model; do not departing from the scope situation that the utility model claim protects; can also make the various deformation such as replacement, simple combination, the scope of asking for protection of the present utility model should be as the criterion with claims.
