If concrete itself has dicoration, the expense of building surface construction, decoration can be saved, and has a kind of Normal juice former
Taste, the aesthetic feeling let nature take its course.
Based on this situation, someone begins to use clear-water concrete.Clear-water concrete be it is a kind of will after concrete formation directly
Expose the concrete as decorative cover.Its it goes without doing any exterior trim, concrete are inherently decorated.It is big that this can be described as one
Leap.But clear-water concrete is relatively high for construction requirement especially curing requirements, for example, cement must be kept to use in same engineering
Same stove is fired, to keep the solid colour of cement.Sand, stone field must be separately protected, ensure its stay in grade.Clear water coagulation
The maintenance processes of soil are equally stringent, otherwise easily concrete surface caused aberration occur.So generally speaking, China is existing
Construction background is difficult a wide range of popularization clear-water concrete.Somebody begins to use other architectural concretes.But current cement
Decoration panel, the variation of shape, pattern rely primarily on the change in shape of concrete mold to realize.Mold has punching block, wood
Mould, the modern designs of plastics etc., it is of all shapes and colors.The characteristics of way is to obtain the concrete of different pattern it is necessary to there is different pattern
Mold.Obviously such process costs are high, hardly possible volume production, the period is long, waste is big.This is also the reason of it fails to promote at home.
Based on this situation, there is report to do concrete casing using transfer technique.Its transfer technique is by by retarder
It is imprinted on and realizes on PVA basement membranes.And including the example that the document enumerates, retarder is usually aqua, and such liquid
After state retarder is imprinted on by silk-screen printing on basement membrane, it can all change liquid retarder in concreting and process of vibrating
The pattern formed on concrete, retarder are extremely easy to happen diffusion, migration, change shape, lead to the amount of local retarder
Not enough, retarding effect cannot be played, pattern or retarder migration are unable to get or changes shape, and is directly resulted in last
Pattern deformation influences the fine degree of pattern.

F, hydraulic giant rinses：The concrete product surface that basement membrane of tearing is rinsed with hydraulic giant, makes aggregates expose, in concrete
Product surface obtains pattern.
It is described subtract strong agent at least contain acid acceptor or foaming agent.
It is described to subtract strong agent by 1~5 parts by weight of acid acceptor or foaming agent, 5~30 parts by weight of film-forming components, viscosity-adjusting agent
15~25 parts by weight of component, 550~570 parts by weight of water composition.
The film-forming components are PVA or gelatin.
The viscosity adjusting materials are CMC or PVA.
The acid acceptor is nitrous acid, carbonic acid, phosphoric acid, metaphosphoric acid, sulfurous acid, acetic acid, formic acid, acetic acid, oxalic acid, benzene
One kind in formic acid or phenol.
The foaming agent is aluminium powder, ammonium salt or zinc powder.
It is described to subtract strong film forming agent and be sprayed on basement membrane by ink-jet printer.
The problem of for background technology, inventor considers to substitute retarder with strong film forming agent is subtracted, described to subtract by force
Acid acceptor or foaming agent in film forming agent can be reacted with alkaline cement to be generated acid compound or generates bubble, to
The intensity for reducing area of the pattern concrete, so as to form phase on concrete product surface with the mode that hydraulic giant rinses in the later stage
The pattern answered.It is preferred that the compression strength of concrete product non-pattern portion matrix is more than 10MPa, the matrix for forming pattern part is anti-
Compressive Strength is less than 2MPa, to be conducive to can preferably be rinsed out the cement of area of the pattern when hydraulic giant rinses.Due to subtract by force at
It is added to viscosity adjusting component in film and adjusts appropriate viscosity convenient for coating, being added to film-forming components makes to be coated in epilamellar subtract
Strong film forming agent can be membranaceous at solid after placing, effectively prevent the later stage pour with subtract in process of vibrating strong film forming agent diffusion,
Migration, the generation for changing the problems such as pattern form.And after concrete is with strong film-forming agent is subtracted, subtracting strong film forming agent also can be effective
It is uniform to penetrate into concrete, keep the pattern line to be formed clearly demarcated, erosion uniform depth, pattern forming precision are high.It is described subtract by force at
The specific viscosity of film can root disturb the equipment and membrane surface that are used when coating roughness reasonably select, do not limit especially herein
Fixed, if sprayed using ink-jet printer, preferred viscosities are 1.5~4.0MPa.s.
The coating method is also not particularly limited, and will particularly preferably be subtracted strong film forming agent and is sprayed on base by ink-jet printer
On film, more other printing technologies such as screen printing mode is flexible simple compared to more.The preferred 0.1mm of coating thickness.
The basement membrane not soluble in water can have burnishing surface material, such as PVC film with any；The type of the concrete
There is no limit can enumerate all kinds of cement such as portland cement, Portland cement, portland slag cement, be suitable for
The sand of various fineness modulus.Note that it is assumed that changing coarse sand into middle sand, depth of pattern will increased.
Advantageous effect：
Present invention process is extremely simple, easily operated, and membranaceous pattern can be formed by subtracting after strong film forming agent is coated on basement membrane,
The pattern will not occur diffusion, migration and be changed with subsequent process steps, after ensureing that subtract strong film forming agent contacts with concrete
It can therewith react in accurate and effective infiltration concrete, reduce the intensity of target area, finally ensure to be formed on concrete
Svelteness is accurate, loses the pattern of uniform depth.
