Abstract: A method for preparing a PET floorboard comprises: hot-melt compounding a printing layer and a wear-resistant layer to obtain a composite layer; providing at least one PET felt panel on the backside of the printing layer of the composite layer, and then performing hot-pressing for fusion attachment and cold-pressing for shaping to obtain a composite panel; coating at least one UV paint layer on the surface of the wear-resistant layer of the composite panel, and then cutting into required sizes and processing edges to obtain the PET floorboard. The PET floorboard provided by the invention has such good flexibility that it will not crack or be defaced when being folded in half around a metal shaft with a diameter of 12.7 mm. Moreover, the PET floorboard is light, has a density of only 700-1000 kg/m3, and has excellent dimensional stability against high and low temperatures and safety.

Abstract: A preparation method of a loose lay plastic floor includes the following steps: (a) subjecting a wear layer, a printing layer, a semi-rigid PVC layer, a core layer and an adsorption layer to hot-melt compounding and shaping to obtain a composite board; (b) coating one or more layers of UV coating on a surface of the wear layer of the composite board; and (c) subjecting the composite board coated with the UV coating to tempering, conditioning and punching to obtain a loose lay plastic floor. The core layer is a stone plastic core (SPC), a wood plastic core (WPC), a high density fiberboard (HDF), or a medium density fiberboard (MDF).
