PVC (polyvinyl chloride) decoration plate prepared from acidification modified white ash

Abstract

The invention discloses a PVC (polyvinyl chloride) decoration plate prepared from acidification modified white ash and belongs to the field of PVC materials. The plate comprises the following ingredients in parts by weight: 100 parts of PVC, 40-70 parts of acidification modified white ash compound lead salt, 5-10 parts of acidification modified white ash compound basic lead phosphite, 5-8 parts ofMBS (methyl methacrylate-butadiene-styrene), 4-6 parts of CPE (chlorinated polyethylene), 4-6 parts of ACR (acrylate), 1-4 parts of paraffin and 2-3 parts of barium stearate. The acidification modified white ash compound lead salt and acidification modified white ash compound basic lead phosphite substitute tribasic lead sulfate and dibasic lead phosphite for manufacturing the PVC decoration plate; comprehensive utilization of a white ash slag resource is achieved; and the plate has a high economic value added, is clean, environment-friendly and good in product performance, exceeds technicalindex requirements of the like products, is better in extrusion and lamination performance, machinability and stability and has a wide application value in an aspect of interior decoration.

Description

technical field [0001] The invention belongs to the field of PVC materials, in particular to a PVC decorative board made of acidified modified white soot. Background technique [0002] PVC decorative board has the characteristics of light weight, heat insulation, heat preservation, moisture resistance, flame retardancy, and simple construction. One of the most widely used decorative materials in China. Patent document CN103739985A discloses a PVC decorative board with high bending strength and impact strength. Tribasic lead sulfate is used as a heat stabilizer in the composition of the decorative board. However, since tribasic lead sulfate is usually composed of lead oxide It is made by reacting with sulfuric acid. In the process of production or use, it will inevitably cause dust to fly and pollute the environment. After the human body inhales it, it is easy to cause lead poisoning and cause harm to human health. Therefore, the existing PVC decorative boards are slightly ...

Problems solved by technology

However, due to the influence of raw materials, process methods, and process conditions, the soot produced by copper smelting has complex components and large fluctuations in phase composition. Toxic and harmful heavy non-ferrous metals, direct discharge will cause environmental pollution, and can only be stored and disposed of as hazardous waste, which does not conform to the basic concept of modern industrial clean production
