Abstract

The invention relates to polyolefin pearl foam and a preparation method thereof. The method comprises the following steps: (1) preparing foaming master batch; (2) preparing flame retardant master batch; (3) preparing calcium carbonate filler master batch; (4) adding raw materials into a high-speed mixer to prepare an ingredient 1; (5) adding raw materials into the high-speed mixer to prepare an ingredient 2; (6) performing double-layer composite extruding: adding the ingredient 1 and the ingredient 2 into a hopper of a double-layer composite sheet extruder to extrude into double-layer composite sheets; (7) performing radiation crosslinking of the composite sheets; (8) foaming the composite sheets; (9) cutting the composite sheets to obtain a finished product. The polyolefin pearl foam prepared by using the method has the advantages of good luminescence effect, easily available raw materials and low preparation cost.

Description
