Abstract

The invention belongs to the technical field of decorative sheet machining, and relates to PVC floors, in particular to a one-time forming type PVC composite floor manufacturing process. The manufacturing process comprises the following steps that parts of a surface layer and parts of a bottom layer are mixed by weight, put onto the upper layer of a co-extrusion double-cone machine and sequentially enter the upper layer and the bottom layer of a calendaring forming machine; parts of a core layer are mixed by weight, put onto the lower layer of the co-extrusion double-cone machine, then subjected to foaming at 210-220 DEG C and enter the middle layer of the calendaring forming machine; one-time calendaring composite forming is conducted, meanwhile, a polyvinyl chloride (PVC) heat transfer film, a polypropylene (PP) heat transfer film or a polyethylene (PE) heat transfer film veneer which is formed through calendaring of the calendaring forming machine is used as a decorative layer to bepasted on the upper surface of the surface layer, and one-time roll forming is conducted through a four-roller press or a five-roller press; and integral forming is achieved through die pressing andcompositing, and one-time forming, cooling and slitting are conducted. The one-time forming type PVC composite floor manufacturing process is simple and high in controllability, a manufactured PVC composite floor has the advantages of being free of formaldehyde, environmentally friendly, non-poisonous, safe, dampproof and the like and has certain anti-microbial and anti-mold effects.

Description

technical field [0001] The invention belongs to the technical field of decorative board processing, and relates to a PVC floor, in particular to a manufacturing process for one-time forming PVC composite floor. Background technique [0002] "PVC floor" refers to the floor made of polyvinyl chloride raw materials. It is made of polyvinyl chloride and its copolymer resin as the main raw material, and fillers, plasticizers, stabilizers, colorants and other auxiliary materials are added to the sheet continuous substrate. Produced by coating process or by calendering, extrusion or extruding process. The main products are: Coiled flooring, made of polyvinyl chloride resin as the main raw material, adding appropriate additives, on the sheet-like continuous substrate, produced by coating process, divided into foamed polyvinyl chloride rolls with substrate There are two types of flooring: PVC flooring and dense PVC coiled flooring with substrates; sheet flooring is made of polyvinyl...
