Description
Technical field
The present invention relates to a kind of novel degradable polylactic acid 3D printing material preparation method and applications.
Background technique
External 3D Systems(computer system), EOS(block chain) etc. large-scale increasing material manufacturing company pass through 3D printing technique
The performance of the plastic products of printing has reached advanced level.The developed countries such as America and Europe basic research, industrialization, engineer application and
Popularization practical all achieves tremendous development, and 3D printing has become one of modern model, mold and effective means of components manufacture,
Preferable application has been obtained in fields such as aerospace, automobile and motorcycle, household electrical appliances, biomedicines.
China 3D prints industry development and is still in the primary stage at present, and technology restricts always using with factors such as consumptive materials
Industry outburst, by taking consumptive material as an example, although 3D printing at present has had 1000 multiple materials available, material hair
Lazy weight, poor universality and the not high feature of performance is still presented in exhibition, plus 3D printing professional standard not yet in whole world system
One, this further constrains the substitutability of material and is converted to the ability of product.In this context, and with 3D plastics are printed
As development priority, 3D printing industry is expected to take the lead in breaking office in consumptive material field consumptive material.3D printing consumables is the pass of industry development
Key element, the material that whole world consumptive material market has been researched and developed at present mainly have plastics, resin and metal etc., and wherein plastics consumptive material is especially
Thermoplastic is most expected.It is expected that thermoplastic will become 3D consumptive material with fastest developing speed, annual growth rate will be up to 20%, the whole world
Advanced 3D printing consumables market to 2019 market values will be up to 6. 5 hundred million dollars, and compound annual growth rate will be up to 17. 9%.
At present thermoplastic 3D consumptive material mainly with PLA and two kinds of ABS.Wherein ABS plastic has excellent comprehensive
Can, have fabulous impact strength, good stability of the dimension, electrical property, wearability, chemical proof, a dyeability, processing and forming and
Machining is preferable.But ABS does not dissolve in most of alcohols and hydrocarbon solvent, and micro- poison, as 3D printing consumptive material, its cost compares
It is higher.
Polylactic acid (PLA) is a kind of novel biodegradation material, is made from starch synthesis, is by corn and cassava etc.
Plant extracts starch by multiple working procedure, through microbial fermentation at lactic acid, then aggregates into polylactic acid.PLA be it is nontoxic, without carcinogenic
Substance, now widely used food additives, during production and application, will not add and generate any has PLA product
Malicious harmful substance.The largest benefit of PLA material is " harmonious coexistence " of it and environment.To environment after being discarded with conventional plastic
Caused by destroy unlike, discarded PLA product " can bury ", by the Nature microorganism natural degradation be water and
Carbon dioxide, as long as and this process 6 to 12 months, be real environment amenable material.
Polylactic acid (PLA) has been also equipped with oneself unique characteristic other than the basic characteristic for having biodegradable plastic,
Mechanical performance and physical property are good.Much lower, the specific advantage as its cost ratio of 3D printing consumptive material ABS:
(1) smell is cotton candy smell when prints PLA, the bad smell for the son that is pungent unlike ABS；
(2) .PLA can print heavy parts model in no heating bed and corner will not tilt；
(3) .PLA processing temperature is 200 DEG C, and ABS requires low in 220 DEG C or more heating temperatures；
(4) .PLA has lower shrinking percentage, and performance is good when the model of printing larger size；
(5) .PLA has lower melt strength, and printer model is easier moulding, and lustrous surface is excellent, beautiful in colour.
Polylactic acid is suitable for the various processing methods such as blow molding, thermoplastic, and easy to process, compatibility is good with degradability, institute
With also very extensive in field of medicaments application, various food utensils (plate, bowl etc.) can be produced, disposable infusion apparatus, exempt to tear open
Type operation suture thread etc., low molecular weight pdlla make medicament slow release packaging agent etc..
This raw material are reproducible living resources, and new century most promising novel is unanimously regarded as by industry
" ecomaterial ".Although PLA material is very powerful, it also has weakness simultaneously: intensity is low, product size stability is poor, 3D is beaten
The risk of print spray nozzle clogging is bigger, heat-resisting and hydrolysis ability is poor, this just produces many restrictions to the use of PLA product.
For the application range of the environmentally protective material of further expansion, in addition to needing to develop intensity and shock resistance
Height is not easy to plug outside the PLA series 3D printing consumptive material of nozzle, improves its comprehensive performance more urgently to improve and develop its application neck
Domain.
Summary of the invention
The object of the present invention is to provide discharging when a kind of printing PLA, cotton candy smell, corner is not tilted, moulding is good, nontoxic
Novel degradable polylactic acid 3D printing material preparation method and application.
Above-mentioned purpose is realized by following technical scheme:
A kind of novel degradable polylactic acid 3D printing material preparation method, by the plastics of injection grade and toughener by mixer into
Row is blended, and smashes in pulverizer, is squeezed out by extruder, carries out crushing acquisition spheric granules macromolecule of uniform size again
Composite material is dried in drying box, pull out finally by wire drawing machine the 3D printing consumables of diameter 1.75mm.
3D printing consumables is used for 3D printing by a kind of application of novel degradable polylactic acid 3D printing material preparation method
Machine.
Beneficial effect
1. the present invention is mainly blended the plastics of injection grade with toughener, the industrialization production of 3D printing consumables is realized,
The fast development for facilitating promotion plastic industry carries out upgradings to some relatively backward traditional industries.
Since current southern china 3D printing consumables company has developed to certain stage, northern market a piece of sky at present
White therefore of the invention research compensates for the market vacancy of northern 3D printing consumptive material, obtained composite material 3D printing consumables
Using be it is very extensive, such as automotive interior product, craftwork, field of biomedicine and other life products, reality is answered
It is very big with being worth.
The present invention is especially the research to the high molecular materials calendering process such as plastics, rubber, achieves preferable achievement, energy
It is enough to provide solution with being blended for toughener for Injection-grade Plastics of the present invention.
Smell, can be in no heating bed feelings for cotton candy smell when the degradable polylactic acid PLA printing that the present invention uses
Under condition print heavy parts model and corner will not tilt；Processing temperature is 200 DEG C, it is low to require；With lower shrinking percentage, i.e.,
It is very good to make also to show when the model for printing larger size；And there is lower melt strength, printer model is easier moulding,
Lustrous surface is excellent, beautiful in colour.
