AI Technical Summary

Technical Problem

Existing PVC edge banding has poor heat resistance, is prone to aging, and has poor antibacterial properties, making it difficult to meet the needs of high-end applications.

Method used

Modified nano-calcium carbonate and hollow antibacterial microspheres are used. The nano-calcium carbonate is modified by grafting reaction of a functional coupling agent. Combined with the preparation of hollow antibacterial microspheres, an edge banding substrate layer is prepared and compounded with hot melt adhesive to form an adhesive edge banding strip.

Benefits of technology

The tensile strength, heat resistance, thermal insulation effect and antibacterial properties of the edge banding are improved, the aging and antibacterial problems of the edge banding are solved, and the needs of high-end applications are met.

Abstract

The invention relates to the field of edge banding strips and discloses an adhesive edge banding strip for furniture and a preparation method thereof. The edge banding strip comprises an edge banding strip substrate layer and a hot melt adhesive layer, wherein the edge banding strip substrate layer comprises: polyvinyl chloride, modified nano-calcium carbonate, hollow antibacterial microspheres, chlorinated polyethylene, and an additive; the modified nano-calcium carbonate is grafted onto the surface of the nano-calcium carbonate by using a functionalized coupling agent and then reacted with 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionyl chloride to form the strip; the functionalized coupling agent is reacted by N-(4-aminophenyl)maleimide with 3-mercaptopropyltriethoxysilane; the hollow antibacterial microspheres are prepared by using an antibacterial monomer prepared by reacting 5-hydroxymethylthiazole and isocyanoethyl methacrylate, sodium p-styrene sulfonate, N,N-methylenebisacrylamide, n-hexane, and cetyltrimethylammonium bromide through emulsion interfacial polymerization and quaternization reaction. The edge banding strip prepared by the invention has excellent tensile strength, aging resistance, heat resistance, heat insulation effect, and antibacterial performance.
