Abstract

The invention provides a plastic profiled bar decorative layer combination material with natural texture for co-extrusion molding, formed by mixing 15-80wt% of plastic substrate, 15-80wt% of composite pigment and 0-50wt% of inorganic powder, wherein the composite pigment comprises pigment or dye with natural color texture effect; inorganic pigment and inorganic powder in the composite pigment need to be respectively and actively processed by a surface conditioning agent or a coupling agent; the combination material provides the surface of the plastic profiled bar with a high-polymer material co-extrusion composite layer with stronger adhesion and endows the surface of the plastic profiled bar with the metal-like texture effects, such as the colors of gold, silver, copper or other natural metal materials. The decorative layer has a certain thickness, high hardness, strong scratch resistance and longer product service life and can be used for industries, such as electronic appliance shells, plastic color windows and doors, plastic profiled bars, furniture sheets, and the like.

Description

technical field [0001] The invention belongs to the field of macromolecular materials, and relates to the formulation and processing technology of a plastic profiled material decorative layer composite material imitating the natural texture of metal, which is manufactured by co-extrusion technology. Background technique [0002] "Replacing wood with plastic and steel with plastic" has become a factual act of replacing natural resources with synthetic materials, but the appearance of plastic products always stays in the transformation of color and shape, and the color effect and material texture can never replace the texture of natural materials. [0003] In the past two decades, since plastic profiles are widely used in construction materials, office furniture, household appliances and other fields, the market is huge, and consumers do not want a large number of synthetic materials to flood homes, offices and public places. Therefore, surface decoration technology products o...
