A kind of ABS composition and preparation method thereof

Abstract

The invention discloses an ABS composition, which comprises the following components in parts by weight: 100 parts of ABS resin; 1-15 parts of glycidyl ester polymer; 0.5-2.5 parts of near-infrared reflective pigment; 0.3-3 parts of toner share. The ABS composition of the present invention is compounded by glycidyl ester polymers and near-infrared reflective black pigments, so that the ABS composition of the present invention can have good marking properties without adding foaming agents and marking agents. Marking effect, the marked mark has the characteristics of high whiteness, slight yellowing, and no stain.

Description

Technical field

[0001] The present invention relates to the technical field of polymer materials, in particular, it relates to a composition and method for preparing ABS. Background technique

[0002] Laser marking is the use of high energy density laser illumination of a workpiece, the surface layer vaporized material, foam, ablation or color change, thereby leaving a method of marking a permanent marker. Tag having fast speed, writing clear, permanent, wear-resistant, environmental protection, etc., are widely used in industrial identification. White laser marking printed in black ABS plastic, mainly using the principle of the resin is irradiated with laser light endothermic foaming is achieved, it is necessary to add a foaming agent, expensive marking laser marking or the like functional additives.

[0003] Commonly used laser marking additive has a function of blowing agent, a marking agent, wherein the blowing agent is the main choice: polymethyl methacrylate; marking agent ...
