Description
Technical field
The present invention relates to cement 3D printing technique fields, and in particular to a kind of component is simple, the 3D printing that has excellent performance is used
Cement material and the method for being molded complicated cement artware using it.
Background technology
Cement material is mostly important one of the civil engineering material of today's society, is done with construction for the development of human society
Go out immeasurable contribution, and with the development of social science and technology, the application of cement in other respects is also more and more extensive,
Especially cement artware is increasingly favored by everybody in Modern Home installing meter.For the cement artware market status and
Practical value is analyzed, and is found after analysing the concrete application that it is in installing meter, cement artware can not only be decorated a little
Sew our living space, domestic environment can also be improved, improve quality of the life, meets us and pursue comfortable environment-protection, individual character letter
Design requirement about shows completely new decorative aesthetics with unique visual angle.
Currently, traditional complicated cement components forming method is the pre-formed method of gypsum mold, this method prepares stone first
Then cream mold smears grease type releasing agent in gypsum mold, merging in gypsum mold also needs to use sealed plastic at docking
Cloth merges, then joints cement material, finally disassembles gypsum mold and is cleaned etc. to obtained complicated decoration cement craftwork
Surface treatment.Not only process flow is complicated for the above method, but also manual operation part is more, flaw easily occurs, to the skilled of worker
Degree has higher requirements, in short, there are many inconveniences for traditional cement artware forming method.
3D printing technique is a kind of emerging cement rapid shaping skill with the 3D printing cement technology that cement material is combined
Art.Material is filled into 3D printer by the technology, is directly printed after equipment reading model, and the cement of high-precision high-quality is formed
Model, solve manufacturing process is cumbersome, human cost is high, fabrication cycle length etc. before prepare it is all present in cement complex component
More problems.
There are many more mature 3D printing cement material and related printing techniques on the market at present, but generally directed to
Be Building class application scenarios, the problems such as there are raw material components more, complicated component, of high cost, complex forming technology.Such as China
A kind of fast vigour wet stock of 3D printing magnesium phosphate cement disclosed in patent CN106278129A, up to upper ten kinds of ingredient, at
Type technique up to five or six steps, it is clear that cannot be used for being molded complicated cement artware.In addition, the 3D printing cement applied at present
Material and technology are used directly to be molded complicated cement artware, and often need in the market are not achieved in surface accuracy and mechanical property
Ask, occur section and it is frangible the defects of.It is therefore desirable to develop a kind of new, the stronger cement artware 3D of specific aim to beat
Print cement material and related forming technique.
Invention content
It is an object of the invention to solve conventional cement craftwork complex forming technology and existing 3D printing cement material and
Forming method is not suitable for the problem of preparing cement artware, provides the 3D printing cement material that a kind of component is simple, has excellent performance
Material and the method for being molded complicated cement artware using it.This method meets the characteristic of water hardening using cement itself, from 3DP powder
The bonding agent that printer head gushes out reacts hardening with finished ground cement, and every layer of powder is bonded together, and thus prints multiple
Miscellaneous cement artware model.To achieve the above object, the technical solution adopted in the present invention is as follows：
A kind of complexity cement artware 3D printing cement material, including cement, liquid adhesive, the liquid adhesive
It is mixed with polyvinylpyrrolidone (PVP), water by one kind in borax, sodium carbonate, calcium chloride.
Further, the mass fraction of borax or calcium chloride or sodium carbonate is 1-10wt% in the liquid adhesive, is gathered
The mass fraction of vinylpyrrolidone is 0.1-0.5wt%.The content of bonding agent can be adjusted according to the setting rate of different cement,
Suitable setting time is selected to contribute to printing shaping.
Further, the cement is in magnesium phosphate cement, calcium-phosphate cement, sulphate aluminium cement, portland cement
One kind.
Further, the cement needs ball milling to filter out particle of the grain size between 100-200 mesh at powdered.
The method for being molded complicated cement artware using above-mentioned cement material, includes the following steps：(a) cement is dry grinded,
The particle for filtering out appropriate particle size obtains finished ground cement；(b) by borax or calcium chloride or sodium carbonate and polyvinylpyrrolidone
(PVP), water mixes, and liquid adhesive is obtained after stirring evenly；(c) using finished ground cement and liquid adhesive as raw material, 3D is utilized
Printer prints complicated cement artware sample, conserves to obtain the final product.
Further, the cement is in magnesium phosphate cement, calcium-phosphate cement, sulphate aluminium cement, portland cement
One kind, the cement granules of grain size 100-200 mesh are filtered out after dry grinding.
Further, the mass fraction of borax or calcium chloride or sodium carbonate is 1-10wt%, polyethylene in liquid adhesive
The mass fraction of pyrrolidones is 0.1-0.5wt%.
Further, protecting maintenance indoor maintenance in water after cement artware sample prints, under room temperature 15--28 days is
It can.
Compared with prior art, the invention has the advantages that：(1) raw material and simple for process, cost is relatively low；(2)
Can rapid shaping moulding and all sufficiently complex cement artware of structure, improve production efficiency；(3) it is molded by the cement material
Obtained complicated cement artware good mechanical properties；(4) it can be molded under the very low ratio of mud (being less than 0.1), and only spray
Printing one time is penetrated, the single ink ejection amount of printer is fixed, and the ratio of mud of printed sample is also fixed.
