Abstract

The invention provides a noctilucent 3D printing photosensitive adhesive. The photosensitive adhesive is prepared from, by weight, 50-80 parts of UV cured resin A, 50-80 parts of UV cured resin B, 0.05-0.1 part of flatting agent, 1-10 parts of wetting agent, 0.2-1 part of defoaming agent, 1-10 parts of noctilucent powder, 3-5 parts of photoinitiator A and 3-5 parts of photoinitiator B. The invention further provides a preparation method of the noctilucent 3D printing photosensitive adhesive. The preparation method comprises the steps that the wetting agent, the flatting agent, the defoaming agent and the noctilucent powder are added into a high-speed dispersing machine, the rotating speed is increased to 600-800 r / min, and then the speed is decreased; the UV cured resin A, the UV cured resin B, the photoinitiator A and the photoinitiator B are added, dispersing is continuously conducted, the materials are mixed to be uniform, and the noctilucent 3D printing photosensitive adhesive is obtained. When the noctilucent 3D printing photosensitive adhesive is coated on a film and irradiated through a UV-LED lamp, the rapid curing capacity is achieved, and the noctilucent 3D printing photosensitive adhesive can be applied to the technical fields such as automobiles, industrial maintenance and medical treatment.

Description

technical field

[0001] The invention belongs to the field of polymer materials, and in particular relates to a luminous 3D printing photosensitive adhesive and a preparation method thereof. Background technique

[0002] High-speed light-curing molding technology has been widely used in the world in recent years, especially 3D printing technology, which is a so-called additive molding technology that mainly manufactures three-dimensional products by adding materials layer by layer. It has low energy consumption, low cost, With the characteristics of high forming precision, it can print any complex parts that cannot be processed by traditional processing methods. There are still some problems in the development of the 3D printing photosensitive adhesive provided at present: the current 3D printing adhesive is mainly made of thermoplastic materials, such as PLA and ABS and other polymer materials, which need to be heated during the molding process, resulting in inconvenient use...
