Recyclable water-based peelable release agent used for 3D printing and production method and application thereof

Abstract

The invention belongs to the technical field of release agents, and discloses a recyclable water-based peelable release agent used for 3D printing and a production method and application thereof. Therelease agent is composed of the following components of, in parts by weight, 4.5-11 parts of film-forming agent, 0.05-0.1 part of defoaming agent, 0.05-0.1 part of flatting agent, 88.7-95.3 parts ofwater and 0.05-0.15 part of preservative. The invention furthermore provides the production method of the recyclable water-based peelable release agent used for 3D printing and the application of therecyclable water-based peelable release agent in 3D printing. The release agent forms release film after being heated and dried, and after being used, the release film can be dissolved again when added into water for heating again, so that recovering and recycling are achieved. By means of the release film obtained through the release agent, the phenomena of buckling deformation, separation from abase board and the like of a printed object in a 3D printing process can be effectively prevented, and lossless separation of the 3D-printed object, a resin casting object of the 3D-printed object and the base board can be achieved, so that unexpected technical effects are achieved.

Description

technical field [0001] The invention belongs to the technical field of release agents, in particular to a recyclable 3D printing water-based peelable release agent and its preparation method and application. Background technique [0002] As a high-precision 3D printer with high cost performance, FDM prints objects by continuously laying thermoplastic melt. However, with the increase of the printed object, when the printed material undergoes the process from solid to molten state, and then to cooling and solidification, the volume of the material shrinks and produces a large internal stress, which is prone to the printed object detaching from the substrate, delamination or warping Defects such as deformation seriously affect the accuracy of printed objects, and even directly lead to printing failure. In view of the above-mentioned problems of detachment of printed objects from the substrate and warping deformation, most of them are currently solved by applying solid glue, wh...

[0004] Chinese patent publication CN201610717285.X discloses a water-based peelable adhesive for display screen processing and its preparation method. The water-based peelable adhesive has good adhesion to resin materials such as PMMA, PC, PET and glass substrates, but It is limited to use as a protective glue and has no pasting effect

Chinese patent publication CN201610059877.7 discloses a release film with excellent peelability. It discloses a release film with a silicone-based release agent on one side and inorganic particles on the other side. The release film is adjusted by inorganic particles It has the advantages of stable adhesion and easy peeling, but due to the existence of inorganic particles, the surface of the film will be uneven, and a release film with a smooth surface cannot be formed.

The release film technology disclosed in Chinese patent publications CN201610793154.X, CN201710116237.X and other patents also has the problem that inorganic particles cause the surface of the film to be rough, and it is difficult to recycle.
