Problems solved by technology

[0003] In order to solve the problem that the price of carbon black and white carbon black, the main fillers in the existing rubber industry, is relatively high and their properties are single, that is, they only have reinforcing properties. When the laterite nickel slag and red mud are directly added to the rubber, it is easy to agglomerate, and the laterite nickel slag-red mud The problem of poor compatibility between the mud-inorganic interface and the rubber-organic interface, the present invention provides a laterite nickel slag-red mud composite rubber filler with flame-retardant and reinforcing properties, in order to solve the above problems

Abstract

The invention discloses laterite nickel ore slag-red mud composite rubber filler with flame retardant and reinforcement performance and belongs to the field of resource recycling. The laterite nickelore slag-red mud composite rubber filler comprises a normal-temperature surface pore-forming mixed solution, a surface modifier mixed solution, an absolute ethyl alcohol-acetone mixed solution, laterite nickel ore slag and red mud. The normal-temperature surface pore-forming mixed solution consists of oxalic acid dihydrate and phosphoric acid; the surface modifier mixed solution consists of a silane coupling agent KH560 and a silane coupling agent KH550; the particle size of the laterite nickel ore slag is 2.8-102.0 mu m. The problems that in existing rubber industry, main filler including carbon black and white carbon black is higher in price and single in function and only has reinforcing performance, laterite nickel ore slag-red mud aggregates very easily after being directly added to rubber and the compatibility of inorganic interfaces of laterite nickel ore slag-red mud and organic interfaces of rubber is poorer are solved, and high-added-value recycling of industrial waste is realized.

Description

technical field [0001] The invention belongs to the field of recycling of solid waste resources, and in particular relates to a laterite nickel slag-red mud composite material used for flame-retardant reinforcing rubber fillers and a preparation method thereof. Background technique [0002] Laterite nickel slag is a non-metallic mineral mainly composed of non-metallic minerals produced after the recovery of metallic minerals by acid leaching of laterite nickel ore. Its main chemical composition is SiO 2 , FeO, Al 2 o 3 , CaO, MgO, Cr 2 o 3 , MnO, etc., where Al 2 o 3 And the content of MgO is higher. Red mud is the waste residue produced in the alumina production process, and its main component is SiO 2 , CaO, Fe 2 o 3 、Al 2 o 3 、Na 2 O, TiO 2 、K 2 O, etc., also contains caustic soda components and trace non-ferrous metals, among which Al 2 o 3 And the content of CaO is higher. At present, the utilization rate of laterite nickel slag and red mud is low, and ...
