Composite red-mud high-molecular synthetic material for building decoration and preparation method thereof

Abstract

The invention relates to a composite red-mud high-molecular synthetic material for building decoration and a preparation method thereof. The composite red-mud high-molecular synthetic material for building decoration disclosed by the invention is composed of the following raw materials in parts by weight: 100 parts of polyvinyl chloride, 30-200 parts of red mud, 3-6 parts of stabilizer, 3-8 parts of impact modifier, 2-6 parts of impact inhibitor, 1.5-3 parts of coupling agent, 0.8-1.7 parts of paraffin, 0.4-1 part of stearic acid, 0-0.8 part of foaming agent, 0-10 parts of foam regulator, and 0-2 parts of ultraviolet light absorber. According to the invention, red mud used as a raw material is utilized for producing various building decoration materials; therefore, resources are saved; more importantly, the worldwide problem of environmental pollution caused by red mud is solved; and thus, the invention is a good thing having dual purposes.

Description

technical field

[0001] The invention relates to a red mud polymer synthetic building decoration composite material and a preparation method thereof, belonging to the field of construction. Background technique

[0002] Red mud is the waste residue discharged from the aluminum plant after extracting alumina. Generally, 1.0-2.0 tons of red mud will be produced for every ton of alumina produced. The world produces about 70 million tons of red mud every year, and my country, as the world's fourth largest producer of alumina, discharges more than 30 million tons of red mud every year. A large amount of red mud not only occupies a large amount of land during the stacking process, but also causes soil alkalinization and groundwater pollution due to the infiltration of its chemical components into the soil. People's long-term intake of these substances will seriously affect their health. The main pollutants of red mud are alkali, fluoride, sodium and aluminum, etc., and its conten...
