Description
Technical field
The utility model relates to 3D printing technique field, in particular to a kind of 3D printing is breathed freely release film.
Background technique
Release film, also known as stripping film, isolation film, seperation film, adhesive block film, fractal film, film, plastic film, masking hole film, silicon
Oil film, silicone oil paper, antiadhesion barrier, type paper, skidding film, that paper of day, release paper.
Under normal conditions in order to increase the off-type force of plastic film, plastic film can be done to plasma treatment, or apply at fluorine
Reason, or apply silicon (silicone) mould release on the surface layer of film material, allow it for a variety of different organic pressure sensitive adhesives (as heat
Melt the pressure sensitive adhesive of glue, acrylic glue and rubber series) extremely light and stable off-type force can be shown.The release film according to needed for difference
The viscosity of off-type force, isolated product glue is different, the corresponding adjustment of off-type force, is allowed to reach in removing extremely light and stable release
Power, release film on the market is mainly double-layer structure, relatively simple, not very practical, and release film layer is not easy to replace, 3D printing speed
The performances such as degree is slow, and adhesiveness is strong, is not easily stripped,
Utility model content
In view of the problems of the existing technology, the utility model provides a kind of ventilative release film of 3D printing.
To achieve the goals above, technical solutions of the utility model are as follows:
A kind of ventilative release film of 3D printing, which is five-layer structure, is respectively as follows: optical gain film, glass from bottom to top
Glass, adhesive layer, macromolecule PE ventilated membrane, release dope layer；The optical gain film can select incident light；It is described
The macromolecule PE ventilated membrane for covering release dope layer is adhered on glass by adhesive layer, facilitates its replacement.
Preferably, light transmittance >=93% of the glass, can carry the weight of 3D printing resin.
Preferably, light transmittance >=92% of the macromolecule PE ventilated membrane, 40 μm of thickness, Air permenbility >=1500g/m2/
For 24 hours, certain Air permenbility, which can be realized, adjusts the purpose that ultraviolet light curing reaction carries out by oxygen, and then improves print speed.
Preferably, the release dope layer by macromolecule PE ventilated membrane coat peeling force≤6g/25mm from
Type dope layer can form the structure of similar non-stick pan.
Using the technical solution of the utility model, have the advantages that practical, release film layer is readily replaceable,
It is not easy to adhere to, be easily peeled off, broken single double-layer structure, film quality greatly improves, and can carry out selectivity to light, lead to
Crossing the certain Air permenbility of ventilated membrane can realize that oxygen adjusts the purpose that ultraviolet light curing reaction carries out, and then greatly improve 3D printing
Speed.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
Referring to Fig.1, the utility model provides a kind of ventilative release film of 3D printing, which is five-layer structure, is arrived by down
On be respectively as follows: optical gain film 1, glass 2, adhesive layer 3, macromolecule PE ventilated membrane 4, release dope layer 5；The optical gain film
1 can select incident light；The macromolecule PE ventilated membrane 4 for covering release dope layer 5 is adhered to glass by the adhesive layer 3
On 2, facilitate its replacement.
The light selectivity of the optical gain film 1, allows the light for meeting convergence angular to pass through, and ineligible
Light be reflected back toward backlight, again in the backlight scatter after return optical gain film, until it is eligible outgoing be
Only.
Light transmittance >=93% of the glass 2, can carry the weight of 3D printing resin.
Light transmittance >=92% of the macromolecule PE ventilated membrane 4,40 μm of thickness, Air permenbility >=1500g/m2/24h, energy
The progress for inhibiting ultraviolet light curing reaction under oxygen effect, can introduce oxygen into resin bottom by macromolecule PE ventilated membrane 4
It forms one layer thin of liquid and inhibits cured layer, avoid consolidation zone from cohering with bottom, so that solidification process is kept continuity, to reach
To many times of effect faster than traditional 3D printing speed.
The release dope layer 5 on macromolecule PE ventilated membrane 4 by coating the release coating of peeling force≤6g/25mm
Layer 5 can form the structure of similar non-stick pan, achieve the effect that 3D printing resin solidification region is not cohered with bottom.
Described the utility model is strong, and release film layer is readily replaceable, is not easy to adhere to, be easily peeled off, and has broken single
Double-layer structure, film quality greatly improve, and can carry out selectivity to light, can realize oxygen by the certain Air permenbility of ventilated membrane
The purpose that ultraviolet light curing reaction carries out is adjusted, and then greatly improves 3D printing speed.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
Under all utility models in the utility model are conceived, equivalent structure made based on the specification and figures of the utility model
Transformation, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
