Problems solved by technology

Most of the bags on the existing market achieve the pearlescent effect by spraying or coating the surface of PC and PC / ABS boards. This post-treatment seriously affects the production efficiency, cost and environmental protection; Various advantages such as environmental protection and low cost have been widely promoted.
[0003] The surface hardness of spray-free ABS products currently on the market is 2B level, low hardness, poor scratch resistance, and difficult to repair scratched materials, which greatly limits the application field of the product

Abstract

The invention discloses an ASA / PCTA / POK composite material and a preparation method thereof, and belongs to the technical field of spraying-free materials. The ASA / PCTA / POK composite material is of a three-layer structure and sequentially comprises an ASA resin layer, a PCTA resin layer and a POK resin layer from top to bottom. According to the invention, the multi-layer ASA / PCTA / POK composite material is obtained through co-extrusion molding, so that the ASA / PCTA / POK composite material has excellent scratch resistance, impact resistance and excellent appearance effect; in addition, in the using process of the ASA / PCTA / POK composite material, the working procedures such as paint spraying or electroplating are not needed, and the requirements for environmental protection and attractiveness are met.

Description

technical field [0001] The invention relates to an ASA / PCTA / POK composite material and a preparation method thereof, belonging to the technical field of spray-free materials. Background technique [0002] With the continuous improvement of living standards and the development of the economy, people are no longer satisfied with the single use value of the product, and the requirements for the performance, design, aesthetic feeling and color of the product are becoming more and more stringent. Most of the bags on the existing market achieve the pearlescent effect by spraying or coating the surface of PC and PC / ABS boards. This post-treatment seriously affects the production efficiency, cost and environmental protection; Various advantages such as environmental protection and low cost have been increasingly popularized. [0003] The surface hardness of spray-free ABS products currently on the market is 2B, which is low in hardness and poor in scratch resistance. The scratched ...
