Abstract

The invention discloses a rapidly-curable luminous 3D printing photosensitive adhesive. The rapidly-curable luminous 3D printing photosensitive adhesive is prepared from, by weight, 50-80 parts of UV curable resin A, 50-80 parts of UV curable resin B, 0.05-0.1 part of a leveling agent, 1-10 parts of a wetting agent, 0.2-1 part of a defoaming agent, 1-10 parts of luminous powder and 3-5 parts of a photoinitiator A and a photoinitiator B. The invention further provides a preparation method of the rapidly-curable luminous 3D printing photosensitive adhesive. The preparation method includes the steps that the wetting agent, the leveling agent, the defoaming agent and the luminous powder are added into a high-speed dispersing machine, and the mixture is dispersed at the rotating speed of 600-800 r / min; then, the UV curable resin A, the UV curable resin B, the photoinitiator A and the photoinitiator B are added, and the mixture continues to be dispersed; after even mixing, the luminous 3D printing photosensitive adhesive is obtained. After coating, the luminous 3D printing photosensitive adhesive has the rapidly-curable capacity after being irradiated with a 385 nm UV-LED lamp.

Description

technical field

[0001] The invention belongs to the field of polymer materials and relates to a photosensitive adhesive, in particular to a fast-curing 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 moldi...
