Abstract

The invention relates to the technical field of resin composition preparation and particularly relates to a 3D printing polymer material with special beautifying effects and a preparing method thereof. The polymer material comprises following raw materials by weight: 60-90 parts of matrix resin, 4.0-10 parts of a compatilizer, 0-30 parts of an inorganic filler, 0.3-2.0 parts of white oil, 0.4-0.6 part of an antioxidant, 0.5-1.0 part of a processing auxiliary agent and 1.0-5 parts of a toner. The polymer material is good in dimension stability, good in bridging effect and excellent in draping performance. The appearance of the polymer material is strong in metallic tactile sensation and pearl effects. The polymer material has one or a plurality of effects selected from heat discoloration, photochromic effects, effects of color changing when sensing water, and the like, and is of great significance for promoting material diversification and functionalization of 3D printing. The preparing method is simple, improves shearing and dispersion for the inorganic filler and the toner to the utmost, and improves properties of the polymer material.

Description

Technical field

[0001] The invention relates to the technical field of resin composition preparation, and in particular to a 3D printed polymer material with special aesthetic effects and a preparation method thereof. Background technique

[0002] Rapid prototyping technology, also known as 3D printing technology, was born in the late 1980s. It is a high-tech manufacturing technology based on material accumulation method. An important branch of 3D printing is personal printing that has emerged since around 2008. The vast majority of personal 3D printers use FDM (Fused Deposition Modeling) to complete printing and molding. The basic principle of this technology is to transfer the thermoplastic polymer filament (the matching diameter of the current mainstream printers is 1.75mm and 3mm) to the high-temperature hot end using gears to melt the polymer and continuously extrude the molten polymer, and under precise positioning Build three-dimensional objects by stacking them lay...
