Description
Technical field
The invention belongs to rubber materials, more particularly to a kind of preparation method of gum filler, gum filler and compounded rubber.
Background technology
Flyash be thermal power plant generate industrial solid castoff, be the larger industrial residue of the current discharge capacity in China it
One.With the development of power industry, the flyash discharge capacity of coal-burning power plant of China increases year by year.The discharge of flyash both causes soil
The environmental pollutions such as ground, water body and air and ecological environment destruction, and the precious resources as silicate material is wasted, it is badly in need of out
High value added product is sent out, is efficiently utilized, to promote China's economizing type recycling economy development.If to total utilization of PCA
Research and processing are not gone into overdrive, it will bring immeasurable consequence to production of energy, comprehensive utilization of resources and environmental protection.
The composition of various regions flyash is different, for Al2O3The high flyash of content generally uses acid system or alkaline process by aluminium from flyash
It extracts, makes full use of regenerated resources, improve the comprehensive utilization value of flyash.Residue of aluminum-extracted pulverized fuel ash has particle thin
The high feature of small, short texture, activity, using with apparent technical advantage and economic advantages in high molecular material.At present
In terms of the utilization of residue of aluminum-extracted pulverized fuel ash is concentrated mainly on construction material, feature is that usage amount is big, but added value is low, from resource profit
It is a kind of waste for property.
Most widely used particulate filler is mainly carbon black, white carbon etc. in rubber industry, and this kind of filler is because of production cost
It is high and price is also high.With a large amount of uses of rubber and its being continuously increased for consumption figure, the demand of filler is consequently increased.
CN102532955A is disclosed《A kind of preparation method of coveredwith nanometer calcium carbonate flyash superfine powder》.This method is with discarded powder
Coal ash is raw material, is carried out at cladding and chemical modification, coupling with nano-calcium carbonate by ultra-fine grinding, activation, then to its surface
Reason, obtains that the coveredwith nanometer calcium carbonate flyash superfine powder that precipitated calcium carbonate is filled in rubber and plastic products can be substituted.
Preferably 32 μm of the fineness of pulverized-coal ash of ultra-fine grinding, residue on sieve≤8wt% in the patent；Modified-reaction temperature is 70 DEG C~90 DEG C,
The flyash superfine powder product granularity that the method obtains is thicker, and technique is more complex.102775816 A of CN are disclosed《Acid system carries
Flyash waste after aluminium is modified the method for preparing gum filler》.This method acid system is carried the flyash waste after aluminium elute to
It is dry, pulverize after neutrality to 300 mesh, organic modifiers is added, mixed at high speed, grinding are gum filler after ageing.The method
Although the cost of rubber product can be reduced, and solid waste coal ash residue of aluminum-extracted can be effectively utilized, reduce ecological ring
The pollution in border, but obtained gum filler granularity is larger, only reaches 300 mesh, and good strengthening action cannot be played to rubber.
