Technical field
The present invention relates to it is a kind of in a big way, a kind of specifically composite for 3D printing.
Background technology
3D printing, also referred to as " rapid shaping technique ", is that one kind does not need conventional tool, fixture and lathe, but with number
Based on word model file, there is the material of adhesion successively to print to manufacture arbitrary shape thing using metal dust or plastics etc.
The technology of product.3D printing technique forms young bird the eighties in last century from photosculpture and landforms forming technique before more than 100 years
Shape, with the development of nearly 30 years, 3D printing technique was advanced by leaps and bounds.
As 3D printing is increasingly becoming the production technology of more main flow, its product manufactured is needed in different environment more
Plus it is durable, and possess necessary anti-ultraviolet property, manufacturing cost is also required to reduction, and 3D printing final effect largely depends on
In using material amount.The factor of restriction 3D printing technique development mainly has two at this stage：Printed material and equipment.3D printing technique
Itself is simultaneously uncomplicated, but available consumptive material is a difficult point.The consumptive material of normal printer is ink and paper, but the consumption of 3D printer
Material is mainly glue and high polymer material and it is necessary to pass through specially treated, and curing reaction speed of material etc. is also required that very
Height, different 3D printing techniques also have different requirements to moulding material.ABS resin, people are used modern 3D printing technique more
Rubber, plastics, sand, casting wax and polyester thermoplastic's plastics etc. are made, these materials are generally powder or sticky liquid, from price
On see that cost of material is expensive, so the cost of current 3D printing material is to restrict the big factor that 3D printing technique further develops,
This just brings inconvenience for the use of people.
The content of the invention
It is an object of the invention to provide a kind of composite for 3D printing, to solve to propose in above-mentioned background technology
The problem of.

Broken, crushing temperature is subzero 140 degrees Celsius of subzero 120-, and grinding time 1-2 hours is crushed to fineness and reaches 240-360 mesh, obtains
To the first mixture；
Step 3, adds high mixer by the first mixture, kaolin, silicon ash and titanium dioxide, treats that temperature rises to 65 degrees Celsius
When, add coupling agent and continue to mix 10-15 minutes, add dispersant and lubricant and continue mixing 8-20 minutes, finally
Toughener mixing 10-15 minutes is added, temperature is maintained at 125-135 degrees Celsius, obtains the second mixture；
Step 4, the second mixture is put into single-screw extruder, the temperature setting of single-screw extruder
For：180-190 degrees Celsius of one area of head, 190-200 degrees Celsius of one area of machine barrel, 200-210 degrees Celsius of 2nd area of machine barrel, the area of machine barrel three
200-210 degrees Celsius；The fused mass come out from single-screw extruder carries out cooling and shaping, obtains being molded filament-type plastic, will
It is molded filament-type plastic to dry, draw and coiling, you can obtain finished product.
It is used as further scheme of the invention：Drying temperature in step one is 38-45 degrees Celsius.
Compared with prior art, the beneficial effects of the invention are as follows：This product uses waste plastic for raw material, and source is wide, valency
Lattice are low, and preparation technology is simple, it is adaptable to large-scale industrial production；In this product each raw material rise synergy, be made into
Product have good toughness, impact strength, and the product printed by 3D printing technique has high-quality, high-impact and high-strength
