Problems solved by technology

[0004] In order to solve the problem that the price of the main filler carbon black and white carbon black in the existing rubber industry is high and the performance is single, that is, it only has reinforcing properties, and the laterite nickel slag is directly added to the rubber, which is very easy to agglomerate, and the inorganic interface of the laterite nickel slag and the organic rubber. The problem of poor interface compatibility, the present invention provides a modified laterite nickel slag for flame-retardant reinforcing rubber filler, in order to solve the above problems

Abstract

The invention belongs to the field of resource recycling and discloses modified laterite-nickel ore slag for flame-retardant reinforced rubber filler. The modified laterite-nickel ore slag is preparedfrom oxalic acid dihydrate solution in mass fraction of 80%-95%, commercially-pure silane coupling agent KH570, analytically-pure absolute ethyl alcohol and laterite-nickel ore slag in particle sizeof 2.8-102.0micron. Problems of high cost and single property namely a reinforcement property of main filler including carbon black and white carbon black in the existing rubber industry, proneness toagglomeration of laterite-nickel ore slag directly added into rubber and poor compatibility of a laterite-nickel ore slag inorganic interface and a rubber organic interface are solved, and high-added-value recycling of industrial wastes is realized.

Description

technical field [0001] The invention belongs to the field of resource recycling, and in particular relates to a modified laterite nickel slag used for flame-retardant reinforcing rubber filler 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. At present, the laterite nickel slag is mainly stored in the open air, which not only occupies valuable land, but also pollutes the surrounding environment and groundwater. Therefore, how to use the laterite nickel slag on a large scale and efficiently to reduce the environmental burden and increase the efficiency of enterprises , is an urgent problem to be solved. [0003] As a widely used polymer materi...
