Abstract

The invention discloses an improved luminous 3D printing photosensitive adhesive. The adhesive is prepared from, by weight, 50-80 parts of UV curing resin A, 50-80 parts of UV curing 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 luminous powder and 3-5 parts of photoinitiator A and photoinitiator B. The invention further provides a preparation method of the improved luminous 3D printing photosensitive adhesive. Wetting agent, flatting agent, defoaming agent and luminous powder are added into a high-speed disperser, UV curing resin A, UV curing resin B, photoinitiator A and photoinitiator B are added after dispersion at a rotation speed of 600-800 r / min, dispersion continues to be conducted, and materials are evenly mixed to obtain the improved luminous 3D printing photosensitive adhesive. The improved luminous 3D printing photosensitive adhesive has rapid curing capacity after being used for coating and irradiated by a 395-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 an improved 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...
