Abstract

The invention provides a preparation method and application of allylic ester resin composite glass fiber photosensitive resin used for UV-curing 3D printing. The mixture mainly comprises the following two raw components by mass percent: 30-50% of allylic ester resin and 70-50% of glass fibers, wherein a radical initiator is 1-8% of the total mixture by mass. The allylic ester resin composite glass fiber photosensitive resin is prepared by mixing the raw components by mass percent and stirring the raw components uniformly at room temperature. After UV-curing 3D printing forming, formed workpieces have high precision, still have good mechanical properties at high temperature and are suitable for special requirements under special conditions, such as manufacturing of key components in the aviation field.

Description

technical field [0001] The invention belongs to the field of rapid prototyping and manufacturing, and in particular relates to an allyl compound for photocuring 3D printing. [0002] Preparation method and application of ester resin composite glass fiber photosensitive resin Background technique [0003] Photocuring 3D printing (Three Dimensional Printing, 3DP), which is a kind of rapid prototyping technology. As a new generation of 3D printing, it uses liquid photosensitive resin to form parts and cures with ultraviolet light. [0004] a technique. It has the advantages of simple operation and fast forming speed. Therefore, the application prospect is very promising. [0005] Photocuring 3D printing uses polymer-based photosensitive resins. Mainly include: acrylate-based photosensitive resin [0006] Grease, fast curing speed, low price, but serious curing shrinkage, serious parts warping; epoxy resin base, polyester [0007] Although the curing shrinkage of urethan...
