Description

The preparation method of masstone pattern transfer concrete
Technical field
The present invention relates to concrete furnishing fields, and in particular to a kind of preparation method of masstone pattern transfer concrete.
Background technique
Transfer concrete is a kind of by slow setting technology the aggregate of concrete surface pattern part to be exposed to being formed The architectural concrete of pattern.It is characterized in that pattern elaborate, can arbitrarily change, compared to general decor material, transfer is mixed Solidifying soil can greatly create space to building designers, can reach fabulous artistic effect.So the development of transfer concrete is got over Come rapider, application range is increasing.
The production method for transferring concrete is to be imprinted on retarder on basement membrane by certain pattern, and coagulation is poured on basement membrane Soil opens basement membrane after concrete hardening, washes away concrete surface with water and obtains corresponding pattern.There are some scholars pair at present Transfer concrete is studied.Jiang Xi is proposed, retarder can be sprayed in PVC film by the pattern of design, by film Figuratum one side casting concrete upward, after concrete slurry solidification, demoulding simultaneously opens PVC film, is rinsed with hydraulic giant mixed Solidifying soil surface, makes it expose pattern.What good fortune of Boulder is refined to use screen printing technique by liquid retarder according to pattern uniform, fine Ground has been printed on basement membrane, is printed to retarder on basement membrane using printing technology, production method is simple and effective.But current turns Print concrete only has black and white pattern, and decorative effect is limited.Publication number 108314929 discloses a kind of colour transfer pattern cement The preparation method of product, 1) by the retarder of retarder not of the same race or various concentration respectively with different colours ink, stabilizer, Water mixing, obtains the transfer ink of different deferred actions;2) it by required pattern flip horizontal 180 degree, and is drawn using transfer ink It makes on transfer carrier;3) it by the cement admixture placement layer by layer of different colours to transfer carrier, is demoulded after maintenance, then it is different The transfer ink of deferred action is attached to cement products surface, and cement products surface forms transfer pattern and cement products surface Slow setting degree is different;4) above-mentioned cement products surface is washed away with water, the cement products surface of different slow setting degree shows difference Color, form colored complex pattern to get to colour transfer pattern cement products.The patent application provides a kind of colored turn The method for being patterned cement products, but still have the following problems: (1) complex process: need individually to prepare the transfer of different colours Ink and subregion printing, individually prepare the cement admixture placement layer by layer of different colours, processing step is more, process operation level is wanted Ask high;(2) surface color is easily spread, and since transfer ink has different colours, is easy diffusion between each other, is led to product surface Color boundaries mix unclear, and pattern fine degree is low;(3) cement admixture placement layer by layer is stood in hardening process, is made by gravity With influence, particulate matter (such as sand) will form natural layering, and fine sand sinks, easily leads to each layer color and mix, influence the final color of product The correct presentation of coloured picture case, pattern fine degree are low.
Summary of the invention
The contents of the present invention are to solve the above-mentioned problems, to provide that a kind of simple process, operation difficulty be low, the fine journey of pattern Spend the preparation method of high masstone pattern transfer concrete.
The technical scheme comprises the following steps:
A, the preparation of sand: sand is classified according to particle size range of different sizes, and a kind of particle size range corresponds to a kind of color;
B, the production of transfer film: retarder is transferred on basement membrane according to layout, transfers retarder concentration in pattern Foundation needs the depth of slow setting and changes;
C, pour colored aggregate mortar: the sand that step a is prepared, at colored aggregate mortar, is cast in as fine aggregate mixing The surface of transfer film;
D, vibrate: sufficiently vibration colored aggregate mortar is to realize interior laminate layer;
E, it pours ordinary mortar: after colored aggregate mortar initial set, pouring one layer of normal sands again on colored aggregate mortar Slurry;
F, it conserves: maintenance a period of time, the concrete substrate hardened;
G, it opens basement membrane: basement membrane is torn from concrete substrate;
H, water rinses: the concrete substrate surface for basement membrane of tearing is rinsed with giant, so that aggregates expose to obtain Pattern.
In the step a, sand can be selected from colored natural sand or the sand after artificially colored.
In the step a, the maximum particle diameter of same color sand and the difference of minimum grain size are not less than 0.3mm.
In the step b, the difference of the difference slow setting depth is not less than 0.3mm.
In the step c, the colored aggregate mortar is poured with a thickness of 3-5mm.
In the step c, the fluidity of the colored aggregate mortar is greater than 130mm.
In the step d, the colored aggregate mortar time of vibration is greater than 20s.
In the step e, the match ratio of the ordinary mortar is identical as colored aggregate mortar.
In the step a, in different gradation range, the big sand of partial size selects shade and density is small, the small sand choosing of partial size It selects thin shade and density is big.
The problem of for background technique, inventor has made intensive studies the prior art, is based on gravitational settling Sink with the fine grained of grain density relationship and particle voids filling mode, big density, and be filled in around coarse granule, will form From the bottom to top by carefully matching state to thick sand grains hierarchical, inventor cleverly utilizes this principle, by different-grain diameter gradation with Different colours are made in the sand of density point, and fine aggregate mixing concrete is used as after being then directly blended, can be naturally formed after standing Product with multilayered color-forming prints retarder on this basis in advance on transfer film, can realize on product different Slow setting depth, the layer of sand that different slow setting depth corresponds to different colours different grain size range open base after concrete hardening Film rinses concrete surface with hydraulic giant, and since the slow setting degree on cement products surface is different, not solidified cement depth is not yet Together, after water washes away, reveal the layer of sand of different colours in different depth, to show masstone pattern.
In the above method, although under prefabricated different gradation different colours sand, do not need to prepare retarder respectively Transfer ink, subregion printing do not need the complex process steps such as point system yet, and operation difficulty is low, simple process;It does not need to slow setting The problem of being mixed into ink in agent, leading to pattern deformation there is no color diffusion generation;Utilize the spy of sand natural layering after pouring Point forms multilayered color-forming, because mixing without color, the problem of pattern accuracy difference;Except to sand progress gradation and color Outside distinguishing, new component is not added, does not increase new processing step, scheme is simple.
The sand can be selected from the sand with natural colour or the sand after artificially colored, and the sand of the natural colour can To be Chinese red color sand, topaz color sand, Snow Flower White color sand, emerald color sand, steel gray color sand, sapphire blue color sand etc..
In the step a, the maximum particle diameter of same color sand and the difference of minimum grain size are not less than 0.3mm, each to guarantee It is that color layer of sand can be effectively layered and have adequate thickness, it is preferred that the particle size range of sand is between 0.15mm~2.36mm, root According to the quantity Demand Design series of layout color, different colours sand at different levels can form multilayer not in the concrete after pouring With the layer of sand of color, further according to different depth locating for layer of sand, printing is able to achieve the slow setting of different slow setting depth on basement membrane Agent, slow setting depth is corresponding with depth locating for layer of sand, to obtain the colorful one pattern.
For the colored aggregate mortar other than fine aggregate has color, other components and proportion are identical as ordinary mortar.
In order to guarantee showing for color comprehensively, the thickness of each layer of sand is preferably not less than 0.3mm in product, thus on basement membrane The difference of slow setting depth achieved by the retarder of regions of different colours is preferably not less than 0.3mm.
In view of slow setting depth is generally within the scope of 0.1-3mm, it should adjust the mortar laminated thickness of colored aggregate to match Slow setting depth, therefore colored aggregate mortar thickness is preferably in 3-5mm.Colored aggregate mortar at this time is excessively thin, should pour after its initial set New one layer of ordinary mortar is built to increase thickness.In view of the consistency problem of colored aggregate mortar and ordinary mortar volume stability, Other than colored aggregate to be changed into the identical general aggregate of gradation, the other proportions and colored aggregate mortar complete one of ordinary mortar It causes.
For the layering for guaranteeing colored aggregate, accelerate movement of the aggregate in mortar by the way of vibration, and promote mortar Mobility is to reduce the resistance of motion of the aggregate in mortar.Preferably, time of vibration is greater than 20s, and Mortar'S Flowability is greater than 130mm。
Further, although sand can form multilayered structure in product, inventor is the study found that this multilayered structure circle Limit is not absolutely stringent, actually also have a small amount of fine sand to exist in intermediate or upper layer layer of sand, therefore preferable particle size is big Sand selects shade, and the small sand of partial size selects thin shade, accordingly even when a small amount of light fine sand is mixed into dark coarse sand, also not It will affect clearly showing for dark images.
The retarder is able to achieve there are many ways to different slow setting depth, such as prints different thickness in different color region The retarder of degree or the various concentration of adjusting retarder or use have the variety classes retarder of different retarding effects Deng.Those skilled in the art can reasonably select as needed.
To sum up, the method for the present invention is simple, operation difficulty is low, with short production cycle, pattern contour obtained is clear, color is rich Richness has good pattern fine degree.
