Abstract

The invention discloses a resin composition for laser marking. The components in weight percentage of the resin composition for laser marking are 30 to 58 percent of PMMA, 40 to 68 percent of toughening agent, 0.01 to 0.03 percent of antimony trioxide, 0.12 to 0.50 percent of carbon black toner, 0.01 to 0.50 percent of oiled color batch powder, 1.00 to 1.19 percent of antibacterial agent and 0.10 to 0.50 percent of lubricating treatment agent. The invention also discloses a preparation method for the resin composition for laser marking. Products formed by the resin composition are suitable for laser marking (carving); pictures and texts of processed geometrical shapes through laser carving have high color contrast, and are consistent in color, thereby the phenomena of cauterization and nigrescence can not occur. Compared with common ABS laser carving materials, the qualification rate of the products of the resin composition after laser carving is improved to 99.98 percent, and simultaneously the products have good antibacterial function.

Description

technical field [0001] The invention relates to a resin composition for laser marking and a preparation method thereof. Background technique [0002] At present, most of the laser marking (engraving) materials used in the market use ABS as the base resin. Although it can be used for engraving, the formed graphics often have serious quality problems such as being burned by the laser, yellowing, and blackening. Antibacterial effect. The engraved products are scrapped or downgraded, and the work efficiency is greatly reduced. Contents of the invention [0003] The first object of the present invention is to provide a laser marking resin composition for the deficiencies of the prior art, which can effectively solve the problem that existing laser marking (engraving) materials are prone to being burnt by laser, yellowing and blackening. Serious quality problem. [0004] Another object of the present invention is to provide a process for the preparation of the above known com...
