Problems solved by technology

[0003] In order to solve the high price and single performance of reinforcing fillers in the existing rubber industry, flame retardant fillers do not have reinforcing properties, montmorillonite-later nickel slag is easily agglomerated when directly added to rubber, and the inorganic interface of montmorillonite-later nickel slag Due to the poor compatibility with the rubber-organic interface and the low added value of montmorillonite and laterite nickel slag, the present invention provides a montmorillonite-laterite nickel slag composite rubber filler with flame-retardant and reinforcing properties. In order to solve the above problems

Abstract

The invention discloses montmorillonite-laterite nickel ore slag composite rubber filler with flame retardant and reinforcement performance and belongs to the fields of high-added-value recycling andrecycling of solid waste resources. The montmorillonite-laterite nickel ore slag composite rubber filler comprises hexadecyl trimethyl ammonium bromide, water, a silane coupling agent KH550-stearic acid mixed solution, absolute ethyl alcohol and a montmorillonite-laterite nickel ore slag mixture. The problems that in existing rubber industry, reinforcing filler is high in price and single in performance, flame retardant filler has no reinforcing performance, montmorillonite-laterite nickel ore slag aggregates very easily after being directly added to rubber, the compatibility of inorganic interfaces of montmorillonite-laterite nickel ore slag and organic interfaces of rubber is poorer and the utilized added value of montmorillonite and laterite nickel ore slag is low are solved, high-added-value recycling of resources and recycling of solid waste resources are realized, and reduction of the cost of the rubber product industry is promoted.

Description

technical field [0001] The invention belongs to the field of high value-added recycling of resources and the field of recycling of solid waste resources, and specifically relates to a montmorillonite-laterite nickel slag composite rubber filler used for flame-retardant reinforcing rubber filler and a preparation method thereof. Background technique [0002] In my country, there are a large number of montmorillonites composed of silicate sheets with nanometer thickness, which mainly include calcium-based montmorillonite, sodium-based montmorillonite, sodium-calcium-based montmorillonite and magnesium-based montmorillonite. However, For the application of montmorillonite, there is currently a problem of low added value. 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 , M...
