Description

A kind of 3D prints furniture ink and preparation method thereof
Technical field
The invention belongs to 3D printed material technical field, relate to a kind of 3D and print the gypsum material of furniture, the present invention is also Relate to preparation method and the using method of this gypsum material.
Background technology
At present, Furniture panel both domestic and external can be divided into solid wood board and the big class of wood-based plate two by material classification.Solid wood board cost High, yield poorly, cost is high, breadth is little, and construction process requirement is high, and the arboreal growth cycle is long.The shortcoming of wood-based plate is that it is water-fast Performance is relatively poor, and glue-line can be aging, long-time bearing ability, and bending resistance and tensile strength are all inferior to sawn timber, and service life is than saw Material much shorter.In today of timber worsening shortages, above two sheet material is faced with huge challenge for existence.
The processing of furniture is to assemble through the punching of machine cuts edge sealing with solid wood board and wood-based plate mostly, this Although method has easy large-scale production, the advantage such as efficiently, but also has disadvantages that, as the most loaded down with trivial details in manufacturing process, cost of manufacture The highest, and waste substantial amounts of timber；And also need to cutting, edge sealing when making furniture, spray paint, assembling etc. processes waste people Power material resources, increase cost on foot, and Hepplewhite is the heaviest and does not has fire-proof function, and the survey data from fire department shows Showing, in the family fire death case that China causes every year, furniture fire accounts for the 2/3 of fire sum, and China is anti-because furniture lacks Fire fire resistance causes fire accidents, causes the malignant event of great casualties and property loss, beats for furniture market Alarm bell.
During traditional Furniture manufacture, due to structure or the restriction of technique, the intention inspiration of many excellent design teachers Can only lay aside and neglect.The furniture of complex model needs through substantial amounts of bonding, cuts, bends and other operation is to be manufactured into little portion Part, then assembles, and therefore, the manufacturing cost of the furniture of complex model is high, marketization difficulty.
It addition, constantly expanding and the development of modern science and technology along with China Furniture Industry scale, furniture market is sent out The large batch of mode of production of change antique traditional furniture having given birth to essence can not meet consumer personalization and diversified need Ask.In this context, have furniture made to order and arise at the historic moment.Have furniture made to order and not only provide service to some high-end users, the most satisfied The individual demand of consumers in general.But, current having furniture made to order still follows the manufacturing process of antique traditional furniture, draws nothing but Having entered modularized design, its manufacture is based on batch production, it is impossible to fundamentally realize the individual demand of all users.Still There are the following problems: scale difficulty；Design, manufacturing expense high；Mounting cost is high.
Some enterprise both domestic and external makes mock-up funiture by 3D printing technique at present.Compared with modelling in early days, In hgher efficiency.But owing to material limits, this personalized mode of production is still within the modelling stage, with tradition Solid wood furniture compare, its use is probably limited.
Summary of the invention
It is an object of the invention to provide a kind of 3D and print furniture gypsum material, solve current furniture material not environmentally, The problem of waste timber；Solve have furniture made to order scale difficulty, design, manufacturing expense is high, mounting cost is high problem；There is provided A kind of free of contamination furniture material of novel environment friendly.
The technical solution adopted in the present invention is:
A kind of 3D prints furniture ink, by percentage by weight 91～96% basic ink, 2～4% retarder and 0.5～5% waterproofing agent composition.
Described basic ink is made up of the following component of percentage by weight, Gypsum Fibrosum powder: 60%～91%, filler: 2%～ 20%, modifying agent: 4%～18%, coagulant: 0.5%～5%, firming agent: 1%～20%, pigment: 0.1～0.5%；Described Gypsum Fibrosum powder be the alpha-semi water plaster stone that straight fire following current calcination method is manufactured, its size is 1 μm～150 μm, comprcssive strength ≥25MPa；Its production technology is: gypsum raw material crushes through three grades, and homogenizing obtains the plaster block of particle diameter 10～20cm, instead Answer and still be heated to 55 DEG C～60 DEG C, after getting rid of the condensed water produced, be passed through the saturated vapor of 1.5～3.5MPa, be dried 5～6h, Then excess steam is drained；Pressure 0.3～0.5MPa, temperature 150 DEG C～160 DEG C, it is dried 7～8h, dried material grinding Obtain Gypsum Fibrosum powder；Described filler is one or both the mixture in silicon dioxide or nanometer silicon carbide；Described modifying agent For a kind of or the most several mixture in polyvinyl acetate, epoxy resin and organosilicon；Described coagulant is anhydrous A kind of or the most several mixture in ethanol, ethyl acetate and glycerol；Described firming agent is diethylenetriamine (DETA), a kind of or the most several mixture in ethylenediamine and 3-diethyl amino propylamine (DEAPA)；
Described retarder is citric acid, sodium citrate, tartaric acid, Soluble tartar., acrylic acid, sodium acrylate, six inclined phosphorus A kind of or the most several mixture in acid sodium and osseocolla.
Preferably retarder is one or both the mixture in citric acid and sodium citrate.
The most preferential retarder is citric acid monohydrate.
Described waterproofing agent is in polyvinyl alcohol, paraffin, silicone waterproofing agent and capillary crystalline waterproof agent (DPS) Plant or the mixture of two or more.
Preferably waterproofing agent be the one in polyvinyl alcohol, silicone waterproofing agent and capillary crystalline waterproof agent (DPS) or The mixture of two or three.
The most preferential waterproofing agent is capillary crystalline waterproof agent (DPS).
The present invention is also on the preparation method of this 3D printing furniture ink: filler pre-treatment: press formula in grinder Add firming agent and filler, rotating speed 500～2000r/min, grind 4～12h；In agitator, press formula add coagulant, in advance Processing filler and modifying agent, mix homogeneously, after 50～57 DEG C of insulations 3～6h, add Gypsum Fibrosum powder and pigment by formula, mixing is all Even, prepare basis ink；Basis ink adds 2～the retarder of 4% and 0.5～the waterproofing agent of 5%, mix homogeneously, prepares 3D prints furniture ink.
The present invention prints the using method of furniture ink also on this 3D: by mass percent 46～the 3D printing of 58% Furniture ink join 41～55% water in, be sufficiently stirred for, mix homogeneously, 3D printing can be carried out.
The invention has the beneficial effects as follows:
(1) use ultra-fine, high-strength alpha-semi water plaster stone as main body dusty material, furniture product intensity is high, resolution is high, Printing error is little, porosity is little, apparent mass is good.
(2) personalized furniture customization is allowed to be possibly realized: 3D prints and embodies extremely strong individualized and intelligentized feature, makes The personalized designs of product with create possibility.Use scene according to personal like and difference, realize design and produce individual Property furniture item customized.
(3) the 3D printing furniture printing ink to manufacture furniture of the present invention is efficient and convenient, and technique is simple, cheap；Furniture finished product The advantages such as fire-proof and water-proof, light weight are high-strength, applied widely, are not only suitable for producing personalized product and are applicable to again large-scale production.
(4) 3D of the present invention prints furniture ink, without formaldehyde, does not also have the release of formaldehyde, meet state in production process Family is about the requirement of " zero formaldehyde " sheet material.The 3D of the present invention prints furniture oils can substitute solid wood board, does not use timber, more ring Protect；There is huge economic benefit and wide market prospect.
(5) 3D of the present invention prints furniture ink, reuses, meet national sustainable development after can reclaiming reprocessing Strategy.
