Abstract

The invention discloses a multicolor anti-static foaming polypropylene bead particle. A formula comprises the following raw materials in percentage by weight: 5 to 12 percent of antistatic functionalauxiliary agents, 1 to 3 percent of antioxidants, 2 to 5 percent of inorganic lubricating agents, 0.1 to 5 percent of metal series foaming auxiliary agents and at most 5 percent of PE (polyethylene) wax, wherein the antioxidants are prepared from any two of antioxidants 1010, antioxidants 1076 and antioxidants 168; the inorganic lubricating agents contain 0.8 to 1.3 percent of antioxidants and 5 to 9.2 percent of metal or metal oxide powder; and the metal series foaming auxiliary agents contain 0.8 to 1.3 percent of alumina power and 4 to 9 percent of dispersing agents. According to the method, through the mutual cooperation of the antioxidants, the inorganic lubricating agents and the metal series foaming auxiliary agents, the metal series foaming auxiliary agents are used for fixing thedistribution of the foamed color masterbatch on EPP particles, and the migration is not allowed, so that the uniform color distribution is ensured, and the regulation of EPP foam holes and the coloring of the color masterbatch are promoted; the problems of steam shaping difficulty and product embrittlement during the addition of conventional lubrication agents are also solved; and the color fastness and the weather resistance of the bead particle product are greatly improved.

Description

technical field [0001] The invention relates to the technical field of EPP beads, in particular to a method for preparing colorful antistatic foamed polypropylene beads with antistatic effect and multiple colors. Background technique [0002] In the field of packaging, EPP has been widely used in the packaging and transportation of electronic components. The traditional market has put forward requirements for EPP in terms of mechanical strength, odor performance and antistatic performance. However, with the continuous progress of enterprise operation and production management, enterprises have put forward more stringent requirements for 6S, among which visual management is a very important means of on-site management. That is, enterprises require 6S rectification through visual signals such as signs, graphics and colors. Visual identification plays an important role in facilitating communication, reducing errors and improving efficiency. It is the premise of making the scen...
