Description

Technical Field

[0001] The invention belongs to the field of polymer material processing aids, and specifically relates to a weather-resistant and toughened ABS edge banding masterbatch and a preparation method thereof. Background Art

[0002] Edge banding refers to a thin strip or roll material used for edge banding of furniture panel components, which has the function of sealing, protecting and decorating the side edges.

[0003] Plastic edge banding is a kind of plastic strip or roll edge banding made of various synthetic resins as the main raw materials (with or without additives), and its surface is plain or printed, extruded with textures, patterns, etc. Classification: mainly polyvinyl chloride (PVC) edge banding, acrylonitrile-butadiene-styrene (ABS) edge banding, polyethylene (PE) edge banding, polypropylene (PP) edge banding, polystyrene (PS) edge banding, polymethyl methacrylate edge banding, etc.

[0004] Among them, ABS edge banding is environmentally friendly, wear-resistant, fireproof, moisture-proof, acid- and alkali-resistant. It also has the advantages of strong adhesion after bonding and not easy to fall off. It is mainly used in various types of mid- and high-end furniture products. In actual production, some edge banding users often encounter the problem of poor toughness of edge banding when using ABS granules (formulated materials) for production. In severe cases, the ABS edge banding will break when folded in half, and downstream furniture companies will encounter "material collapse" when cutting the edge-sealed boards in multiple layers. In addition, ABS resin contains unsaturated double bonds and has poor weather resistance. If exposed to light for a long time, the ABS edge banding will turn yellow and discolor, affecting the quality of the appearance. Summary of the invention
