Abstract
The invention provides a producing method of rubber reinforcing agent, especially using coalash as raw material. Its character: drying the coal ash from burning coal, making high-fineness crushing and winnowing, and then adding silane coupling agent in reaction kettle for processing to obtain black carbon substitution. It reduces the environmental pollution.
Description
Technical field
The invention provides a kind of production method of rubber reinforcing filler, particularly produce the method for rubber reinforcing filler with pulverized fuel ash as raw materials.
Background technology
The strengthening agent of black rubber goods use now mainly is a carbon black, owing to produce the sooty complex process, its price per ton surpasses 3500 yuan more, and under the prerequisite of assurance rubber item quality, its production cost is also just high.
Summary of the invention
The purpose of this invention is to provide a kind of new rubber reinforcing filler and the production method of this strengthening agent.
The object of the present invention is achieved like this: the flyash that obtains behind the bituminous coal combustion is dried, make water content be lower than 1.5%, then by high fineness air separation disintegrator pulverize, selection by winnowing, carry out magnetic separation when pulverizing, remove its ferrous contaminants, selection by winnowing makes flyash particle diameter after the pulverizing less than 60 μ m, the flyash that obtains after the selection by winnowing adds silane coupling agent at reactor, temperature of reaction is controlled at 90 ℃ ± 5 ℃, in 20 minutes reaction times, just can obtain this school glue strengthening agent.
With the rubber reinforcing filler that method of the present invention is produced, suitable through test to the reinforcing effect and the carbon black of rubber item, can make the rubber item cost reduce by 25%; The flyash in power station is utilized effectively, reduces environmental pollution, social benefit and ecological benefits are all very remarkable.
Description of drawings
The present invention does not have accompanying drawing.
Embodiment
Embodiment 1:
Utilize the flyash in a certain power station, suburb, Tianjin, its major ingredient is SiO
2Account for 52.3%, AL
2O
3Account for 26.7%.Get flyash after the power plant burning and be placed on the drying plant and dry, make the flyash water content be lower than 1.5%, the flyash of drying through high fineness air separation disintegrator pulverize, selection by winnowing.Carry out magnetic separation when pulverizing and remove its ferrous contaminants, regulate air quantity, the particle diameter that makes flyash is less than 60 μ m, then above-mentioned flyash is placed reactor, under stirring action, slowly add silane coupling agent, controlled temperature is at 90 ℃ ± 5 ℃, in 20 minutes reaction times, just can obtain this rubber reinforcing filler.
