Abstract
The utility model discloses a concrete water retaining curing membrane that consists of a water absorbing material layer that is made of natural or synthesis fiber membrane that is stuck by a modified starch, cellulose, protein or water-absorbing material layer that is made by certain hydrophilic long-chain chemical. A punched membrane is arranged above the water absorbing material layer as the upper membrane, a punched plastic membrane is used under the water-absorbing layer as the lower membrane. The retaining curing membrane can greatly increase service life(can reach one month) and is more convenient to be sued or transported. Water retaining function is as long as 18 to 36 hours. Besides, the retaining and curing effect is improved.
Description
Technical field: the utility model relates to the water-preserving curing film for concrete that a kind of concrete curing phase that is applied to build buildings such as rigid pavement, roadbed, bridge uses.
Background technology: 00126699.3 discloses a kind of water-preserving curing film for concrete, is one or two or more kinds the absorbent material film made that is adhesive with the starch by modification, cellulose, protein or some hydrophilic long-chain compound of 10-30 gram on the thin-film carrier of or synthetic fibers natural at every square metre.After using in the concrete curing phase, can improve this product the anti-folding of concrete, compressive property.It is not long that but this product is in use laid inconvenience, application life, not anti-wind and trample.
Summary of the invention: the purpose of this utility model is to provide a kind of long service life, transports and use a kind of water-preserving curing film for concrete convenient, that also maintenance effect is improved.
One deck was by being adhesive with the absorbent material layer of being made by starch, cellulose, protein or some hydrophilic long-chain compound of modification on natural or the synthetic fibers film in the middle of this curing film comprised, the film that it is characterized in that being provided with one deck punching in the top of this layer absorbent material layer as on film, the plastic sheeting that is provided with one deck punching below the absorbent material layer as under film.
Last film can be the colored plastic film that scribbles one deck printing ink, can be the color masterbatch film also, or scribbles the color masterbatch film of one deck printing ink.
It is convenient to use this kind curing film can improve application life, transportation and use greatly.The curing film that waters sufficient water need not water, can economize on water 8～10 times in 18～36 hours, saved 3～6 times of resources such as artificial, had also reduced the loss of equipment such as water pumper, waterr transporting vehicle, also maintenance effect had been improved.
