Abstract

The invention belongs to the technical field of red mud recycling, and particularly relates to a red mud hollow plastic profile and a preparation method thereof. The red mud hollow plastic profile isprepared from the following raw materials in parts by weight: 50 parts of polyvinyl chloride resin, 30-35 parts of red mud, 15-30 parts of industrial tailings, 30-50 parts of waste PP plastic powder,0.5-1.2 parts of a foaming agent, 5-15 parts of a foaming regulator, 30-35 parts of a plasticizer, 3-7 parts of a stabilizer, 8-12 parts of an impact modifier and 0.5-4 part of a surfactant. A productprepared from the red mud hollow plastic profile is good in processing property, excellent in ageing resistance and flame retardance, low in water absorption rate, good in toughness, high in acid andalkali resistance and small in size change rate.

Description

technical field [0001] The invention belongs to the technical field of red mud reuse, and in particular relates to a red mud hollow plastic profile and a preparation method thereof. Background technique [0002] The chemical composition and mineral composition of red mud vary due to the composition of bauxite, the production process (sintering method, mixed method or Bayer method), the material composition of additives in the production process, and the composition of newly formed compounds. The main chemical component of red mud is silica (SiO 2 ), calcium oxide (CaO), ferric oxide (Fe 2 o 3 ), alumina (Al 2 o 3 ), sodium oxide (Na 2 O), titanium dioxide (TiO 2 ) and potassium oxide (K 2 O), in addition to containing traces of other non-ferrous metals. [0003] Red mud is the polluting waste slag discharged when the aluminum industry extracts alumina. Generally, for every ton of alumina produced, 1.0 to 2.0 tons of red mud are incidentally produced. As the world's ...
