Abstract

A hard multi-layer composite PVC floor belongs to the technical field of floors. The hard multi-layer composite PVC floor is prepared from the following steps of stick-pressing, specifically, stacking a wear resistance layer, a color film layer, a medium material layer, a substrate layer and a base material layer in a tray sequentially, and compositing to produce a product by conducting one-time stick-pressing through a hot press and a cold press; and UV tempering, specifically, conducting coating on the product processed in the first step through a coater and placing the product in the firing line to conduct tempering in order to remove internal stress. The hard multi-layer composite PVC floor is simple in technology, and the attachment is completed relying on heat, the hard multi-layer composite PVC floor contains no harmful substances, such as glue, heavy metal, phthalate, and formaldehyde, the floor shrinkage rate and the warping rate are all less than or equal to 0.1%, so that the hard multi-layer composite PVC floor is applied to broader geographical area ranges, physical indexes of the floor is stable and reliable, and the chemical indexes of the floor meet the international and national standards.

Description

technical field [0001] The invention belongs to the field of floor technology, in particular to a hard multi-layer composite PVC floor. Background technique [0002] Most of the existing multi-layer composite PVC floors contain harmful substances such as glue, heavy metals, phthalates, and formaldehyde, which do not meet environmental protection requirements, and the floor shrinkage rate is large, easy to warp, deform, poor in ductility and toughness, and easy to Low temperature embrittlement, not impact resistant. Contents of the invention [0003] Aiming at the above-mentioned problems existing in the prior art, the object of the present invention is to design and provide a technical solution for a hard multi-layer composite PVC floor, which has a simple process, and the bonding is completed by heat, and does not contain glue, heavy metals, orthophthalic acid. Grease, formaldehyde and other harmful substances, floor shrinkage rate: ≤1‰, stable and reliable physical indi...
