Fabrication technology for PVC plastic floor

Abstract

The invention provides a fabrication technology for a PVC plastic floor. The fabrication technology comprises the steps that raw materials are weighed, the raw materials comprise, by weight, 50-100 parts of resin powder, 10-30 parts of light calcium carbonate, 1-2 parts of stearic acid, 2-6 parts of GB-101 titanium dioxide, 0.8-1.2 parts of polyethylene wax, 1-3 parts of barium stearate, 2-6 parts of antioxidants, 5-10 parts of epoxidized soybean oil, 2-6 parts of rare earth, 3-6 parts of modified heat stabilizers, 2-4 parts of filling matrix and 0.4-0.8 part of foaming agents, and the weighed raw materials are mixed in a high speed mixer at 160 DEG C; the mixed raw materials are subjected to one-time extrusion molding in a high pressure double-screw extruder with the temperature controlled at 210 DEG C; extrusion-molded materials are leveled in a vacuum environment; vacuum-leveled materials are forcedly cooled to obtain a floor substrate; the forcedly-cooled products are subjected to multicolor printing; multicolor-printed floor substrate is obtained; a 3D printed solid-wood-imitating stripe layer is installed on the multicolor-printed floor substrate; and UV high-abrasion-resistance paint is painted on the floor substrate with the installed solid-wood-imitating stripe layer to obtain the PVC plastic floor. According to the fabrication technology for the PVC plastic floor, the shortages and defects of laminate floors and vitrified floors are overcome.

Description

technical field [0001] The invention belongs to the manufacturing process of the floor, in particular to a manufacturing process of the stone-plastic floor. Background technique [0002] At present, rigid polyvinyl chloride plastic sheets are widely used in domestic industry, agriculture, and civil buildings, but due to their poor impact resistance, aging resistance, heat preservation, fire prevention, sound insulation, and secondary processing, adding toughening agents and processing The dispersion of the agent is uneven, the physical and mechanical properties cannot meet the national standards, and the manufacturing cost is relatively high, so that it is limited in use and cannot meet the needs of industry, agricultural production and civil construction. Contents of the invention [0003] The purpose of the present invention is to provide a manufacturing process of stone-plastic flooring to solve the problems in the background technology. [0004] The present invention ...
