Abstract

The invention discloses a stone-plastic composite floor production line, which includes steps of material preparation, extrusion, finishing, coating, quality detection, and packaging. The material preparation includes two steps of pre-treating waste ore powder and preparing a PVC composite material; the extrusion includes steps of material loading, extrusion, vacuum shaping, track drawing and cutting; the finishing includes steps of heavy sanding thickness fixation, dedusting, double-end-milling and four-side planing; the coating workshop includes work steps of: two times of putty paint, one time of sanding paint, three times of priming paint, three times of finishing coat, one time of varnish, one time of wear-resistant paint and three times of sanding and dedusting treatment. The production line achieves high-additional-value and full-automatic recovery of waste ore powder. The stone-plastic composite floor is super-water-resistant, flame-retarding and heat-insulation and is high instrength and toughness, is free of formaldehyde release and can be recycled by 100%. The production line is low in investment and is quick to work, has good production adaptability, and has extensivepromotion and application prospect.

Description

technical field [0001] The invention belongs to the field of floor production, in particular to a stone-plastic composite floor production line. Background technique [0002] At present, there are more than a dozen domestic enterprises producing stone-plastic composite flooring, such as "Jishiduo stone-plastic non-slip flooring" produced by Yuguang Group and Taiwan Youmao Co., Ltd. through the introduction of advanced technology from the United States, but the market share is less than 3%. Stone-plastic composite flooring is mainly used in some outdoor engineering projects in China, and it is not used much for home interior decoration. The price of stone-plastic composite flooring is about tens of yuan per square meter to 300 yuan per square meter. [0003] In recent years, many enterprises in our country are facing the pressure of industrial transformation and upgrading, as well as resource protection, energy conservation and environmental protection. For example, stone pr...
