Abstract

The invention relates to a low-melting-point 3D printing material and a preparation method thereof. The 3D printing material has a melting point of 60-150 DEG C, is free of the problem that the final product performance is affected due to large shrinkage and is environment-friendly, non-toxic and odorless and free of ultrafine particles during printing process. The printing material comprises the following components: a toughening agent, wax, tackifying resin, stearic acid, an antioxidant, a pigment and the like and can be applied in industries such as dewaxing casting.

Description

A kind of low melting point 3D printed material and preparation method thereof

Technical field

The present invention relates to a kind of low melting point 3D printed material and preparation method thereof, belong to the Material Field of rapid shaping.

Background technology

Rapid shaping (Rapid Prototype, RP) technology is a kind of advanced manufacturing technology developed rapidly the nineties in 20th century, is a kind of gordian technique of serving production new product development.It plays positive pushing effect to the products innovation, shortening new-product development cycle, raising product competitiveness etc. of promoting enterprise.This technology, since appearance, has been widely used gradually in the production of countries in the world, and expedites the emergence of out an emerging technical field thus.Current rapid shaping technique mainly comprises fused glass pellet (Fused Deposition Modeling, FDM), selective laser sintering and moulding (Selective Laser Sintering, SLS), Stereolithography (stereo lithography apparatus, SLA), shaping (the Laminated Object Manufacturing of laminated solid body, the technology such as LOM), wherein FDM is with fastest developing speed, and application at most.

FDM refers to that thread thermoplastic material sends shower nozzle to by wire drive feeder, is heated to molten state in the showerhead, extrudes through nozzle.The filamentary material of molten state is extruded out, and the path controlled according to the individual-layer data of three-dimensional software extrudes and the position coagulation forming of specifying, and layer by layer deposition solidifies, and finally forms whole three-dimensional objects.The operating environment of FDM is clean, safety, and technique is simple, easy handling, and does not produce rubbish, has therefore greatly widened operation occasion.Its raw materials provides with the form of spool silk, is easy to carrying and quick-replaceable.

All adopt ABS and PLA as matrix close to 95% for FDM consumptive material at present, its print temperature, usually at about 220 DEG C, belongs to middle temperature FDM consumptive material.The current research of beautiful Country Illinois Polytechnics finds, uses ABS and PLA polymkeric substance higher as printer ultra-fine grain (UFP) quantity discharged of plastic raw materials, ER for emission rate with use laser printer or burning cigarette close.Because volume is small, UFP can be deposited on lung and directly be absorbed in blood.UFP concentration is higher relevant with the development of lung cancer, apoplexy and symptoms of asthma, the chemical composition of ABS and PLA discharge is not pointed out in detail in report, but existing proof display ABS is poisonous before this, and PLA is the polymkeric substance with biocompatibility, has been widely used in making pharmaceutical capsule.Also there is the large problem of shrinking percentage as 3D printed material in ABS and PLA in addition, and gained end article often exists warpage, affects product performance.This just impels the 3D printed material that we develop a kind of low melting point, environment-protecting asepsis is harmful, shrinking percentage is little.

In addition, low melting point 3D printed material has a lot of potential application, such as lost wax process.Present domestic lost wax process substantially adopts and manually manufactures wax-pattern, wax-pattern often needs several workman just can complete one to several months that works, and adopt 3D printing technique only to need a few hours to complete, and preparation precision is much higher than craft, but domesticly there is no used in lost wax casting 3D printed material at present, market blank out.

Summary of the invention

For the deficiency of existing FDM consumptive material, the object of this invention is to provide a kind of low melting point 3D printed material and preparation method thereof, its fusing point is 60-150, DEG C and to there is not shrinking percentage large and affect the problem of end article performance, simultaneously print procedure environment-protecting asepsis evil, odorlessness, without ultra-fine grain.

In the present invention, material prescription adopts toughner 5%-80%, wax 5%-90%, tackifying resin 1%-60%, stearic acid 0%-20%, oxidation inhibitor 0%-5%, pigment 0%-5%.

Described toughner is chlorinatedpolyethylene, styrene butadiene thermoplasticelastomer, ethylene-vinyl acetate copolymer, terpolymer EP rubber and ethylene-octene segmented copolymer, or their combination.

Described wax is polyethylene wax, ethylene-vinyl acetate copolymer wax, Microcrystalline Wax, clorafin, investment cast wax, Poly Propylene Wax, or their combination.

Described tackifying resin is C5 petroleum resin, C9 petroleum resin, hydrogenated aromatic petroleum resin, terpine resin, Gum Rosin, or their combination.

In the present invention, the preparation process of material is:

1) each raw material weighs in proportion;

2) by high-speed mixer mixing 0.1-2000 minute;

3) by twin screw extruder mixing plasticizing, and by dicing machine granulation;

4) by single screw extrusion machine wire drawing, the silk of pull-out can be directly used in 3D and print.
