Abstract
A non-painted thermoplastic resin composition including viscose rayon so as to embody a marble pattern and a method for making it are disclosed. The viscose rayon is included in the thermoplastic resin composition to minimize the deterioration of physical properties while minimizing weld lines and flow marks during an extrusion process, and a luxurious outer appearance of a marble pattern is embodied without additional post-processing or painting process. The non-painted thermoplastic resin composition includes 80-90 parts by weight of a thermoplastic resin composition, 0.1-5 parts by weight of a carbon fiber, and 0.1-3 parts by weight of viscose rayon based on 100 parts by weight of the entire resin composition. The viscose rayon provides an effect of minimizing weld lines and flow marks during injection, improving physical properties, and providing the luxurious appearance of the marble pattern.
