Abstract

The invention relates to a metal-imitating ABS modified material. The metal-imitating ABS modified material consists of the following components: 70-95 parts of ABS, 0.5-10 parts of pigments, 1-5 parts of a coupling-lubricating composite modifier, 5-10 parts of a tackifier, 0-10 parts of filler and 0.1-1 part of an antioxidant, wherein the trademark of the coupling-lubricating composite modifier is YY-503, and the number-average molecular weight of the coupling-lubricating composite modifier is 3000-5000; a low melting point of the coupling-lubricating composite modifier is 75 + / - 5 DEG C, and a high melting point of the coupling-lubricating composite modifier is 150 + / - 10 DEG C; the tackifier is C5 petroleum resin with average molecular weight of 1000-2500. The metal-imitating ABS modified material can be used for overcoming the problems that weld marks are severe, the metal effects are not good and the impact strength is declined in the prior art, and has a wide application prospect in the industry of plastic products.

Description

technical field [0001] The invention belongs to the technical field of plastic modification, and in particular relates to a metal imitation ABS modified material and a preparation method thereof. Background technique [0002] Plastic coloring can give plastic parts color and good appearance effect, and it is an indispensable and important link in the plastic processing industry. Compared with metal parts, plastic parts have the advantages of low density, high cost performance and corrosion resistance. [0003] In order to improve the decorative effect of plastic parts, the prior art usually uses electroplating or spraying metal colors on the plastic surface. The plastic surface electroplating process is long and requires multiple steps such as surface cleaning, roughening, electroless plating, electroplating, and water washing. During the production process, more wastewater and waste liquid will be generated, which will seriously pollute the environment. Surface spraying t...
