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-ferrochrome slag is easily agglomerated when directly added to rubber, and the inorganic interface of montmorillonite-ferrochrome slag Due to the poor compatibility with the organic interface of rubber and the low added value of montmorillonite and ferrochrome slag, the invention provides a composite rubber filler of montmorillonite-ferrochrome slag with flame-retardant and reinforcing properties. In order to solve the above problems

Abstract

The invention discloses montmorillonite-chromium iron slag composite rubber filler with flame-retardant and reinforcing properties, and belongs to the field of high-added-value recycling of resourcesand the field of recycling of solid and waste resources. The montmorillonite-chromium iron slag composite rubber filler with the flame-retardant and reinforcing properties comprises cetyl trimithyl ammonium bromide, water, a silane coupling agent KH550-stearic acid mixed solution, acetone and a montmorillonite-chromium iron slag mixture. The problems that in the existing rubber industry, reinforcing filler is high in price and simple in property, flame-retardant filler does not have reinforcing property, if montmorillonite-chromium iron slag is directly added in rubber, agglomeration is quiteeasily caused, compatibility of a montmorillonite-chromium iron slag inorganic interface and a rubber organic interface is poor, and the additional value of utilization of montmorillonite and chromiumiron slag is low are solved, high-added-value recycling of resources and recycling of solid waste resources are realized, and reduction of costs for 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-ferrochrome slag composite rubber filler for flame-retardant and reinforcing functions 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. Ferrochrome slag is chromium-containing waste slag produced when chromium-containing ferroalloys are smelted by pyrometallurgy. It is mainly produced when high-carbon ferrochrome is smelted by submerged arc furnace method. Its main chemical composition is SiO 2 , Fe 2 ...
