Description
Technical field
The present invention relates to a kind of paraffin print die material, with the spy such as low-shrinkage, low melting point and high intensity, high rigidity
Point, belongs to the Material Field of rapid shaping.
Background technology
3D printing is a kind of emerging rapid shaping technique, can pass through printing device by special printed material according to design
3D models successively print increase material to manufacture three-dimensional objects.GRC(Fibre reinforced concrete)Plate has that complex contour is changeable, makes
The characteristics of type is different, traditional GRC moulds are made using the splicing of the materials such as plank, gypsum, cement, silica gel, the numerous length of operation,
It is very high to mould labor claim, it is time-consuming to take a lot of work.The rise of 3D printing technique gives GRC Mold Makings another good selection,
Using 3D printing automation, efficiency high, material and the advantage such as artificial are saved, by the printing of inexpensive, reusable edible the step of material one
Mould into needed for GRC, and then GRC plates are made, can greatly save the material and energy waste, shortening system of Mold Making process
Make the duration, improve producing efficiency, and the automated production level of GRC industries is greatly improved.
Current commercialized 3D printing material is generally powder or thick liquid, from price costly(From several
Hundred arrive tens of thousands of first per kilograms), and commonly using once just discarding, cause cost rising and environmental pollution etc. seriously to ask
Topic.Using mould needed for 3D principles printing building product, it is necessary to special research and development are suitable for inexpensive, the reusable edible of building trade
And the mold materials of 3D printing process requirements can be met.And olefin material can repeat tens times and recycle, in being GRC industries
The mold materials of preferable environment-friendly type.Common natural paraffin wax, synthesis paraffin hardness are low, and intensity is not high, fusing point is too low, simultaneously because
Paraffin heat conductivility is poor, and internal heat difficulty passes to out, is used directly as mold materials, it may appear that problems with, 1. solidifies
Speed is slow, influences 3D printing efficiency, and the block internal-external temperature difference for 2. printing is big, produces big thermal stress uneven, causes impression block
The easy cracking phenomenon of tool;3. paraffin molten point scope is too wide, and the temperature printed with fused deposition method is not easily controlled.China
A kind of eutectic 3D printing paraffin is disclosed in patent 201510096056.6, because melting range is larger, intensity is not high, be only applicable
In the use of small mould, it is impossible to suitable for large scale building element mould.
The content of the invention
It is an object of the present invention to be directed to above-mentioned weak point, develop a kind of 3D special in architectural decoration and beat
Seal wax mold materials.
Large volume 3D printing modified paraffin material of the invention, is formed by the configuration of following raw materials by weight:Paraffin
40-80%, enhancing hardening agent 10-40%, crystallization nucleating agent 4-20%, thermal conductivity conditioning agent 4-15%.
Described paraffin is using one or two the combination in natural paraffin wax, synthesis paraffin.
Described enhancing hardening agent is using one or more combination in polyethylene, polypropylene, polybutene.
Described crystallization nucleating agent uses calcium stearate, Sodium stearate, one or more combination in zinc stearate.
Described thermal conductivity conditioning agent is using the one kind in graphite, metal dust;Described metal dust uses copper powder or aluminium
One or more combination in powder.
The invention also discloses the preparation method of described large volume 3D printing modified paraffin material, including:
(1)Paraffin, enhancing hardening agent, crystallization nucleating agent, thermal conductivity conditioning agent are weighed in proportion;
(2)Under 80-120 DEG C of heating condition, stirring mixing 1-500 minutes;
(3)By the broken material that can be directly obtained for 3D printing of mixed powder after cooling.
Described modified paraffin material, its melting range is 92-96 DEG C, it is adaptable to fused glass pellet technique, its shaping
After the direct processing of mould prepares building element, powder of the circulation as new die can be again crushed, recycling number of times is 15-35
It is secondary.
The beneficial effects of the present invention are:
1. the enhancing hardening agent such as polyethylene, polypropylene, polybutene is used, hardness, the intensity of olefin material is effectively increased, is conducive to
Realize building element large volume mould.
2. the heat conductivility of printed material is improved with graphite, metal dust additive, it is to avoid large volume thermal conductivity is uneven
The problems such as crack of die for causing.
3. crystallization nucleating agent calcium stearate, zinc stearate are used, odium stearate effectively improves the crystal property of olefin material,
Regulation and control paraffin prints fusing point in narrow range.
4. can directly coordinate special 3D printing equipment after production gained feed powder is broken carries out fusion sediment printing, and need not be outer
Plus other printing auxiliary agents.
5. olefin material reusable edible, the die surface for printing is smooth.
