Abstract

The invention discloses desulfurized ash-kieselguhr compound rubber filling with synergic reinforcement-flame retardance performance and a preparation method of the filling and belongs to the field ofsolid waste resource recycling. The filling comprises water, stearic acid, desulfurized ash and kieselguhr. The preparation method of the filling comprises the steps of mixing and dispersing water and a silane coupling agent to form a silane coupling agent solution, mixing and stirring the desulfurized ash and the kieselguhr to form a desulfurized ash-kieselguhr mixture, and mixing and stirring the desulfurized ash-kieselguhr mixture and the silane coupling agent solution to form the desulfurized ash-kieselguhr compound rubber filling. The filling solves the problems of higher price and a single function of major filling, namely carbon black and white carbon black, in the rubber industry, improves mechanical properties and flame resistance of rubber, achieves industrial waste recycling, promotes benefit increase of a metallurgical enterprise and cost reduction of the rubber product industry, and meets the current industrial development requirements of energy conservation, environmental protection and circular economy.

Description

technical field [0001] The invention belongs to the field of recycling of solid waste resources, and in particular relates to a desulfurization ash-diatomite composite rubber filler with reinforcing-flame-retardant synergistic performance and a preparation method thereof. Background technique [0002] As my country controls and reduces SO 2 With the continuous increase of emissions, flue gas desulfurization has entered a stage of rapid development. With the successive installation of desulfurization devices, there are more and more desulfurization products (semi-dry desulfurization ash, referred to as desulfurization ash). The composition of semi-dry desulfurization ash is extremely complex, consisting of desulfurization agent, desulfurization product and fly ash, and the calcium sulfite in desulfurization ash is very unstable in the process of being utilized. Diatomaceous earth is a siliceous rock whose main chemical composition is SiO 2 , due to the high impurity conten...
