Polyurethane-acrylate Composite Emulsion Applying to the Pre-coated Adhesive Film

摘要

This paper studied on the application mechanics and characteristics of the polyurethaneacrylate composite emulsion applying to the pre-coated adhesive film of paper and plastic laminating. The formula design and synthesis method of the polyurethane-acrylate composite emulsion was researched, and the physical properties of the copolymer emulsion was tested by infrared spectroscopy (IR), particle size analysis, gel permeation chromatography (GPC). According to mix the waterborne polyurethane acrylate emulsion to the waterborne rosin emulsion, the hot melt pre-coated adhesive was obtained. The experimental results based on the physical properties and image analysis of the pre-coated adhesive film of paper and plastic laminating showed that: the adhesive film coated by this hot melt adhesive had a high gloss and adhesive force, it improved the application performance of the pre-coated adhesive film of paper and plastic laminating in the printing and packaging industry.
