Problems solved by technology

Although this preparation method effectively solves the problem of flow marks easily produced by introducing traditional aluminum powder pigments into the plastic matrix on the basis of maintaining a good metallic luster, the aluminum powder is easily broken and damaged after being sheared by twin screws, which affects metal effect
Kingfa Science and Technology patent CN104629245A discloses a spray-free ABS composition with special aesthetic effects and its preparation method and application. In this patent, the special effect powder is coated with an aqueous polymer dispersion into microspheres and then dispersed into ABS resin , although the compatibility of special effect powder and ABS resin is obviously improved, the flow mark formed on the surface of the product during extrusion or injection molding is eliminated, and the weld line is lightened, but the special effect powder is coated with a water-based polymer dispersion into a micro The preparation process of the ball is complicated, which affects the production efficiency

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...
