Colorful antistatic EPP beads and preparation method thereof

Abstract

The invention discloses colorful antistatic EPP beads and a preparation method thereof. The EPP beads are prepared by a double-screw extruder, a foaming reaction kettle and dyeing equipment, wherein the dyeing equipment comprises a workbench; supporting legs are fixed to the four corners of the bottom of the workbench through bolts; an electric sliding rail is fixed to the center of the top of theworkbench; an electric sliding block is embedded in the inner wall of the electric sliding rail; a bearing plate is arranged at the top of the electric sliding block; an electric telescopic rod is fixed to the top of the bearing plate; a sealing plate is fixed to a piston rod of the electric telescopic rod; a containing box is installed at the top of the sealing plate; and fixing through groovesdistributed at equal intervals are formed in the top of the containing box in a penetrating mode. When pigment is sprayed on the surfaces of the EPP beads for heating and baking, in order to enable the EPP beads to be heated uniformly and enable raw materials to be dried more quickly, the EPP beads are suspended above the fixing through grooves to avoid contact dead corners, so that the raw materials on the surfaces of the EPP beads can be dried quickly.

Description

technical field [0001] The invention relates to the technical field of EPP beads, in particular to a colorful antistatic EPP beads and a preparation method thereof. Background technique [0002] EPP, that is, polypropylene plastic foam material, is a new type of foam plastic, EPP is polypropylene plastic foam material, a high-crystalline polymer / gas composite material with excellent performance, and has become a The fastest growing environmentally friendly new pressure-resistant cushioning insulation material. EPP is also an environmentally friendly material, which can be recycled and reused, and can be naturally degraded without causing white pollution. [0003] Expanded polypropylene is a foam with excellent properties. Light weight, high strength, good chemical resistance, high temperature resistance, excellent energy absorption characteristics, and the product is green and environmentally friendly, so EPP is replacing traditional foam materials and EPS foam plastics in...

Problems solved by technology

And most EPP products cannot make the surface color of the product dry quickly and remain intact during the production process, which will waste a lot of time in the drying process, and the surface color will not be completely dry during the production process. blemishes caused by contact
