Embodiment 2

[0028] The raw material formula is shown in the following table:

[0029]

[0030]

[0031] Wherein, the dihydric alcohol is 1,6-hexanediol; the photoinitiator is 2,4-diethylthioxanthone.

[0032] The preparation method of the 3D coating comprises the following steps: after melting and mixing epoxy acrylate and acrylonitrile-styrene-acrylate copolymer, stirring evenly, then adding 1,6-hexanediol diacrylate, rich Malic acid, glycol, dimethoxyphenylacetic acid, photoinitiator, just stir well.

[0033] The thixotropic rate of the coating prepared in this embodiment is 20Pa, the yield value is 15Pa / s, and the Baume degree is 55°Be.

[0034] The raw material of 3D paint is sprayed onto the PAN-based carbon fiber cloth with adhesive backing, and the paint coating is cured rapidly under the irradiation of ultraviolet light; then the nozzle sprays the next layer of paint according to the preset shape, and then it is cured by ultraviolet light after spraying ; In this way, laye...

Abstract

The invention discloses a self-adhesive chip paint and a preparation method thereof. The self-adhesive sheet coating comprises adhesive fiber cloth and a 3D paint coating, and the 3D paint coating is coated on the adhesive fiber cloth, and the raw materials of the 3D paint include by weight: acrylonitrile-styrene 20-25 parts of acrylate copolymer, 40-50 parts of epoxy acrylate, 8-10 parts of 1,6-hexanediol diacrylate, 4-5 parts of fumaric acid, 4-5 parts of glycol, 1-2 parts of dimethoxyphenylacetic acid, 0.1-0.2 parts of photoinitiator. The coating of the self-adhesive chip coating of the invention is stable, the coating does not crack or fall off in the air after coating the surface of the fiber cloth, has high bonding strength, and has good application prospects.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a self-adhesive chip coating and a preparation method thereof. Background technique [0002] 3D printing technology is a multi-disciplinary cross-border integration technology system. It is a technology based on digital model files, using bondable materials such as powdered metal or plastic, and constructing objects by layer-by-layer printing. The technology has applications in aircraft parts, architectural models, footwear, industrial design, biomedicine and food, but research in paving areas such as surface coatings is still in its infancy. The two key factors in 3D printing coating technology are materials and equipment. Materials are not only an important material basis for the realization of 3D printing coatings, but also the main bottleneck restricting the development of 3D printing coatings technology. [0003] There are few studies on 3D printing coatings in the prior art, espec...
