Description
Technical field
The utility model relates to a kind of water-preserving curing film that cement cementitious structures such as reinforced concrete construction thing, concrete road, dam, bridge pier used in curing time that is applied to.
Background technology
Cement cementitious structure water-preserving curing is an important step of engineering construction, the water-preserving curing of cement cementitious structure directly has influence on the quality of engineering, traditional way is again with fibrous matter or the coverings of common plastics film such as straw, sawdusts after cement cementitious structure is laid moulding, regularly water then, watered once in general every 2-3 hour, to keep the moistening normal aquation of cement that makes, reach the effect of maintenance.This method cost height, maintenance effect is poor.
In recent years, a kind of curing film that contains one deck absorbent material layer of domestic appearance, as 1, Chinese patent＜application number〉00126699,＜denomination of invention〉a kind of water-preserving curing film for concrete＜applicant〉Huang Jie, No. 7＜the digest in Qing Yuan road, Changsha, Hunan〉the present invention relates to a kind of cement pavement of building, the water-preserving curing film for concrete that concrete curing phase in fields such as bridge uses is the starch by modification that are adhesive with 10～30 grams on the thin-film carrier that every square metre of natural or synthetic fibers or the mixture of the two are made, cellulose, one or two or more kinds absorbent material layer of making of protein or some hydrophilic long-chain compound.Use this kind curing film can need not water at 10～72 hours after the concrete casting, can reduce 5～10 times of water, electricity, resources such as artificial, also reduced the loss of equipment.
2, Chinese patent＜application number〉01257450,＜denomination of invention〉water-preserving curing film for concrete＜applicant〉Shenghua Sci-Tech Development Co., Ltd., Changsha, No. 7＜digest in Qing Yuan road, Changsha, Hunan〉the utility model discloses a kind of water-preserving curing film for concrete.It comprises that one deck is 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, the top of absorbent material layer is provided with the film of one deck punching as last film, and the below of absorbent material layer is provided with the plastic sheeting of one deck punching as following film.Use this kind curing film improved greatly application life, transportation and use convenient, once water behind the sufficient water and need not water in 18-36 hour, improved maintenance effect.
3, Chinese patent＜application number〉96207045＜authorization notification number〉2248726＜applying date〉1996 years 03 month 28 days＜denominations of invention〉cement concrete pavement maintenance pad＜applicant〉Xie Yongcheng, Minqing, Fujian Province liberation No. 59 Minqings, street urban engineering project company＜digest〉the utility model is a kind of cement concrete pavement maintenance pad, it is characterized in that having the joining upper and lower plastic film layers 3,4 of periphery, the bottom side of last plastic film layers is provided with the stingy post 5 that is positioned at maintenance pad closed cavity.In the time of on the cement concrete pavement after the maintenance pad covers construction, on the one hand because the covering of maintenance advance capital for body can prevent the water evaporates in the concrete, on the other hand, because the radiant heat of the sun, maintenance advance capital for body heats up and conducts heat to the road surface, simultaneously, the air of its inner chamber has played the effect of heat storing and heat preserving again.Its application can be shortened the curing period on road surface greatly.
4, Chinese patent＜application number〉00229537＜applying date 03 month 29 days＜notice of authorization day in 2000 02 month calendar year 2001 07 day＜denomination of invention concrete curing Cover Gasket＜applicant Chen Xuebin, 30 No. 2＜digests in 101 streets, Metallurgy, Qingshan District, Wuhan City, Hubei Province street〉the utility model is the invention about a kind of suitable concrete and cement mortar health water conservation Cover Gasket.It is characterized in that it is responsible for (4) by the water inlet that inlet opening (3) is arranged on plastics health film (5) and the pipe and forms through bonding, mesh (9) is arranged on the health film (5), its periphery is aproll networking (7), infiltration hole (6) penetrates foster film (5), be equipped with attached water at the reverse side of health film (5) and mould post (8), structure forms through blowing on health film (5) and the film, be book shape sealing water cavity (10), water advances to be subjected to mesh and aproll networking to act on slow stream after the Cover Gasket to soak, ooze to the health film, mould concrete or the cement mortar that the post water conservation uninterruptedly soaks into needs health by attached water.Use it can improve construction quality, be beneficial to civilized construction, and the saving of labor that can effectively economize on water, foster operating expenses can be reduced significantly.This product is widely used in can improving the engineering construction comprehensive benefit in highway, bridge, square and the engineering constructions such as other concrete and cement mortar.
Though above-mentioned disclosed document has certain improvement than traditional maintenance process, owing to have defective on its structure and the absorbent material layer formula, maintenance effect is undesirable.
Summary of the invention
In order to change the situation of prior art, the inventor explores through many researchs, has designed a kind of cement cementitious structure water-preserving curing film, and it has improved maintenance effect greatly, and reduces construction cost.
Technical solution of the present utility model is:
This cement cementitious structure water-preserving curing film is composited by four layer materials, and the superiors are sealant, and next coming in order are last absorbent material layer, perforated plastic layer and following absorbent material layer, and following absorbent material layer is layered on the face of cement cementitious structure.
Above-described sealant is fluid-tight plastic sheeting, can be films such as white or dark polyethylene, polyvinyl chloride, polypropylene.
The above-described absorbent material layer of going up can adopt formations such as converted starch, natural fiber, plant half fiber, anticorrisive agent, cementing agent, mineral matter, absorbent material with following absorbent material layer.
Above-described perforated plastic layer is that films such as polyethylene, polyvinyl chloride, polypropylene are made the size in hole and distance: the aperture is the 5-15 millimeter, and fore-and-aft distance is 10-90 centimetre between two holes, and lateral separation is 20-50 centimetre.
This cement cementitious structure water-preserving curing film can be synthetic in factory's one, also can the split manufacturing, the one sintetics needs to spill sufficient water on the cement cementitious structure earlier after transporting to the scene, curing film is covered on the cement cementitious structure then, sprinkles water on curing film again; The split product is transported to on-the-spot back absorbent material layer under cement cementitious structure shop earlier, and watering makes it drenched, spreads perforated plastic layer and last absorbent material layer then, rewaters, and lays sealant at last.
Be compared with the prior art, the utility model has the advantages that:
1, need not water in 500 hours, real cost of production reduces greatly, and maintenance effect significantly improves.
2, two-layer absorbent material layer is arranged, promptly increased one deck absorbent material layer, its water retention property strengthens greatly.
3, easy to use.
