Abstract
The invention relates to a NON-PVC plastic floor and a manufacturing process thereof, belonging to the technical field of plastic floors. The invention adopts PET-P, PET-G or PP resin, calcium powder, various lubricants, processing aids and the like to mix and synthesize NON PVC-LVT floor and NON PVC-SPC floor products which are processed by secondary extrusion of an extruder after pelleting by a pre-special extruder, and uses PET-P, PET-G or PP resin to replace PVC which is considered to be toxic by people originally, so that the manufactured LVT floor and SPC floor have comprehensive physical indexes, performance, service life and the like which are all higher than those of replaced products; the invention also carries out antibacterial hydrophobic treatment on the prepared floor, so that the prepared plastic floor has better antibacterial hydrophobic performance.
Description
Technical Field
The invention belongs to the technical field of plastic floors, and relates to a NON-PVC plastic floor and a manufacturing process thereof.
Background
The plastic floor used in the world at present is a LVT floor and SPC floor product which are mixed and synthesized by adopting PVC resin (polyvinyl chloride, english name: polyvinyl chloride), calcium powder, various lubricants, processing aids and the like, wherein the PVC resin is considered to have a plurality of defects, chlorine is considered to have influence on human health, but the demand on the floor is particularly large (mainly European and American market), so that the PVC floor is always sought to replace the original PVC synthetic series indoor floor.
The invention adopts PET-P (polyethylene terephthalate, english name: polyrthylene terephthalate), PET-G (polyethylene terephthalate-1, 4-cyclohexanedimethanol ester) or PP (polypropylene, english name: polypropylene, processing aid, etc. to mix and synthesize NON PVC-LVT floor and NON PVC-SPC floor products which are processed by extruding through a specially-made extruder after pelleting, and replaces original people to consider toxic PVC with PET-P, PET-G or PP, and the comprehensive physical index, performance, service life, etc. of the manufactured LVT floor and SPC floor exceed that of the replaced products.
Disclosure of Invention
