Description
Technical field
The present invention relates to 3D printing field, more particularly to a kind of biodegradable 3D printing reinforcing material.
Background technology
The development of 3D printing technique proposes new requirement to 3D printing material, by taking melting extrusion forming technique as an example, need to consider plastics fuse dimension and processability is designed to nozzle temperature, to print large-scale hollow product, then must take into consideration how to separate the packing material at center with skin-material, must also consider that both have good caking property before separation, it is to avoid skin-material is collapsed.
Existing 3D printing consumptive material is main with PLA, and based on the homogenous material such as ABS, PA, PVA, because above-mentioned various materials have limitation, poly-lactic acid material high cost, material are easily deformed more than 55 DEG C;A kind of ABS (acrylate/butadiene/styrene terpolymer), common engineering plastics are processed smell weight, are easily deformed in processing is extruded;PA is a kind of nylon material, and expensive, processing difficulties, processing smell weight, processing environment are severe;PVA water-soluble materials be mainly used in printing support material consumption it is few, and processing due to PVA decompose easily produce toxic gas.Composite（Composite materials）It is with a kind of material as matrix（Matrix）, with a kind of material as reinforcement（reinforcement）The new material for combining.Various materials are mutually learnt from other's strong points to offset one's weaknesses in performance, produce cooperative effect, the combination property of composite is better than former composition material and is met various different demands.So as to widen the range of application of constituent material.Although compound species is enriched but the rarely found application for having composite for 3D printing consumptive material very much, main consumptive material material with PLA, ABS, based on the homogenous material such as PA, PVA.Not only low-carbon environment-friendly, processing are easily, excellent in mechanical performance, dimensionally stable, surface gloss be high but also the performance such as printing smoothness for polylactic acid/carbon fiber composite material.
In sum, widen 3D printing consumptive material species, improve consumptive material physical property, must be supplemented in existing consumptive material species, composite can not only make full use of the one of which material advantages can also mutually to learn from other's strong points to offset one's weaknesses in performance with another material, more excellent new material is prepared, and it is easy to process prepared.
The content of the invention
It is an object of the invention to provide a kind of biodegradable 3D printing reinforcing material.The composite is according to the compatible general principle of macromolecular material, combined by reasonable selection and matched, make full use of one of which material advantages to make up the defect on another material property, obtain the performances such as low-carbon environment-friendly, excellent in mechanical performance, dimensionally stable, surface gloss be high.
In order to realize the purpose of foregoing invention, the present invention provides following technical scheme：
（1）A kind of biodegradable 3D printing reinforcing material, is made up of following components in parts by weight：PLA（PLA）：75-80 parts of carbon fibers:25-20 parts；Toughener：4-8 parts；Compatilizer：0.2-5.0 parts of auxiliary agent：0.1-2.0 parts.The toughener is o-phthalic acid dibutyl ester；Compatilizer include maleic anhydride grafting polymer, by methyl methacrylate, butadiene, styrol copolymer copolymerization terpolymer；By styrene, propylene be fine, GMA copolymerization terpolymer（SAG）One or more compatilizers therein are used cooperatively.
（2）The compatilizer maleic anhydride grafting polymer includes that maleic anhydride is grafted POE.
（3）The auxiliary agent includes lubricant, nucleator, dispersant, heat stabilizer, and one or more are used in mixed way.
The advantage of the invention is that：
（1）Carbon fiber high-strength degree, high-modulus are make use of, the intensity of PLA is improve.
（2）Using compatilizer is added, improve PLA and carbon fiber, toughener phase interface bonding strength, increase material compatibility, improve this 3D printing consumptive material composite comprehensive mechanical property.
（3）The 3D printing consumptive material composite for preparing of the invention is nontoxic, low-carbon environment-friendly, and combination property is superior, with economic worth and wide market prospects very high.
