Abstract
The invention discloses a kind of 3D printing light cure silicone rubbers and its preparation method and application.It is prepared by the component including following mass fraction：Contain 100 parts of the polysiloxanes of vinyl, 1.5~10 parts of the small molecule crosslinking agent containing two or more sulfydryls, 0.3~2 part of photoinitiator, 0.1~2 part of surface modified silicon dioxide microballoon, 50~70 parts of solvent in end.The fast reaction under ultraviolet light cures the polysiloxanes that the present invention contains vinyl using end with sulfydryl, its hardening time reaches within 3 s under room temperature, without bad smell after solidification, material property is good, print procedure does not need backing material, process for preparation is solvent-free or a small amount of solvent, cubical contraction are small；In addition, preparation method is simple, the product after photocuring has stronger tearing toughness and suitable hardness, can meet the 3D printing material of the requirement of Medical filling material, have a extensive future.
Description
Technical field
The invention belongs to 3D printing technique fields.More particularly, to a kind of 3D printing light cure silicone rubber and its system
Preparation Method and application.
Background technology
3D printing technique, also known as increases material manufacturing technology are a kind of threedimensional models for establishing object with computer, and as
The technology for relying on straight forming, is bioengineering, material processing and forming, automation control, multiple subjects such as computer modeling
Intersect, compared with conventional molding techniques, it does not need conventional tool, fixture and multi-step process, can be in an equipment
It produces the part of arbitrarily complicated shape automatically and accurately by program control, and greatly reduces manufacturing procedure, significantly contract
The short R＆D cycle of new product, reduce R＆D costs.3D printing technique is quickly grown in recent years, in aviation, manufacture, mould
Tool, education, medical treatment, food etc. have developed more and more application directions.Add without high temperature in 3D printing implementation process
Heat reduces energy consumption, is not necessarily to special solvent, reduces environmental pollution, ultra-violet curing is rapid, and production efficiency greatly improved.3D
The development of printed material is one of 3 big key technologies of 3D printing technique, and material bottleneck has become limitation 3D printing development
Matter of utmost importance.The backbone structure of silicon rubber is polysiloxane structure, and chemical property is stablized relatively, clinically as medical material
The using effect of material has been obtained for being widely recognized as medical field, and there are many major companies all the medicine of exploitation silicon rubber at present
Strategic objective of the use scope as oneself.It is with higher temperature tolerance, resistance to oxidation, hydrophobicity, flexibility, permeability, resistance to
It is aging transparency height, physiological inertia, good, nontoxic, tasteless, not carcinogenic etc. with tissue and blood adhesion, biocompatibility
A series of good characteristics.Due to these characteristics of silicon rubber itself, polymethyl siloxane just becomes medical macromolecular materials
It is middle than more typical organosilicon macromolecule material.
But the hardening time of silicon rubber is longer, mobility prevent its from keep printing accuracy, it is therefore desirable to one
A support material completes the 3D printing of labyrinth；In addition, the hydrophobicity of silicon rubber and lower surface free energy, limit
It is printed while effective with other materials；Moreover, existing silicon rubber can release niff in print procedure, therefore mesh
The preceding 3D printing for silicon rubber still has larger problem, and the 3D printing of silicon rubber is than relatively difficult to achieve.Currently, can successfully realize
The technology of silicon rubber 3D printing, is mainly the following：(1) Hinton et al. has invented a kind of carboxylic second using hydrophilic and hydrophobic
The method that alkene polymer gel support material prints silicon rubber, in this method after the silicon rubber mixing of two-component, through 3D printer
Printing, cures, is successfully realized the 3D printing of silicon rubber at ambient temperature.But it needs support material in print procedure
Material, and hardening time is longer, and after the completion of solidification, need progress proper treatment to remove support material, process is relatively complicated.
(2) Chinese invention patent《A kind of preparation method of 3D printing ultraviolet curing transparent silicone resin composite material and application》(patent
Number CN105331115A) disclose a kind of 3D printing ultraviolet curing transparent silicone resin composite material, the preparation of this kind of material
Cheng Shi, first, with organosilicon materials and alkoxy silane with acryloxy, under the action of catalyst, warp is solidifying in a solvent
Peptization glue method prepares the organic siliconresin prepolymer with acryloxy；Secondly, the organosilicon materials with acryloxy are dripped
It is added in White Carbon black, obtains the reinforced filling that acryloxy is modified；Finally, it is taken off after prepolymer, filler, photoinitiator being mixed
Bubble, obtaining can be with 3D printing ultraviolet curing transparent silicone resin composite material.The disadvantages of this method is that stock preparation process is multiple
It is miscellaneous, excessive high hardness, it is easy to chipping.(3) in addition, Chinese invention patent《3D printing is with silicon-containing nano gel photocuring tree
The preparation method and applications of fat》(patent No. CN106146754A) describes a kind of 3D printing silicon-containing nano gel photocuring
The preparation process of the preparation method and applications of resin, this kind of material is by modification organic silicon oil and acrylic ester monomer, chain
Transfer agent, radical initiator and organic solvent are added in reaction kettle, by purification of products after reaction, obtain silicon-containing nano gel light
Solidified resin.But need to use a large amount of organic solvent in the stock preparation process of this method, do not meet Medical filling material
It is required that and product need to purify.
In order to promote the development of 3D printing technique, needing to develop at normal temperatures has certain mobility and lower viscous
Degree, curing rate be fast, without bad smell, 3D printing plastic emitting effect is good, cubical contraction is small after material molding, print procedure is not required to
Backing material is wanted, and the product after photocuring has stronger tearing toughness, has suitable hardness, can meet medical fill out
Fill the 3D printing material of the requirement of material.
Invention content
The technical problem to be solved by the present invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of 3D printing photocuring
Silastic material, lower viscosity, curing rate be fast, without bad smell, 3D printing plastic emitting effect is good, volume after material molding
