Natural fiber modified composite wrapping plate with low emission and low smoke density

Abstract

The invention discloses a natural fiber modified composite wrapping plate with low emission and low smoke density. The natural fiber modified composite wrapping plate comprises a wear-resistant layerand a substrate from outside to inside, wherein the substrate is formed by compositing natural fiber and a PVC base material, further improvement lies in that the natural fiber is wood meal or straw;the natural fiber surface is treated with a natural fiber surface composite treatment process (ethylene glycol / coupling); a group of synergistic low-molecular removers are adopted during preparation and combined with equipment subjected to specific structural transformation. The natural fiber modified composite wrapping plate has low emission and low smoke density and is environmentally friendly,and large-scale utilization of the natural fiber can be realized.

Description

technical field [0001] The invention relates to a PVC composite material, in particular to a natural fiber modified composite packaging board for packaging. Background technique [0002] Natural fibers have the characteristics of rich sources, renewable, degradable, and high specific performance.
