Description
Technical field
The present invention relates to synthetic reaction device technical field, produce the special high dispersive of radial particularly to one white
The reactor of white carbon black.
Background technology
Precipitated hydrated silica, also known as white carbon, its chemical formula is SiO2·n H2O.White carbon is rubber industry weight
The supporting material wanted, is used for tire tread by white carbon, especially for radial, can significantly reduce the rolling of tire
Dynamic resistance, can keep preferable anti-ice slip and anti-slippery simultaneously, and its wearability only slightly reduces.
Sulfuric acid precipitation method with waterglass as raw material is to have realized the existing of industrialized production white carbon both at home and abroad at present
Technique, the technical characteristics of sulfuric acid precipitation method is: in precipitation reactor, and in certain density waterglass, segmentation adds one
Determining the concentrated sulphuric acid of concentration, and control the pH value in whole course of reaction, reaction equation is: Na2O·mSiO2+H2SO4+n H2O
→ mSiO2(n+1) H2O ↓ +Na2SO4, filters out Na by dilute silicon dioxide oar liquid of gained through filter wash2SO4Female
Liquid, the silica filter cake obtained is processed through pulp tank and obtains dense silica slurry, and is dried by exsiccator
Realize solid-liquid separation, final prepared product white carbon.
Although it is simple that traditional sedimentation method prepare silicon dioxide technique, but produce high dispersive product and be difficult to, and disperse
Property difference directly affects the reinforcing of white carbon, causes the reason of this situation mainly to have following two aspect: to be first viscosity
Impact, the viscosity of sodium silicate solution is not very big, but when viscosity of sludge meeting after primary particle and solid phase precipitation generation
Significantly rise, reach the hundreds of times even hundred times of water glass solution viscosity, the rapid increase of viscosity, have a strong impact on continuation
The sulphuric acid added contacts with being sufficiently mixed of waterglass feed liquid, so sulphuric acid or waterglass local over-concentration easily occur and causing whole
The inhomogenous phenomenon of precursor reactant, thus cause product structure consolidation, particle of once coming into being is big, and after reunion, particle is bigger, is difficult to
Rubber disperses；Secondly, being affected by pH to silicic acid polymerization strong reaction, different pH reaction rates differs greatly, and deposits
At the pH that a fastest maximum point of reaction is corresponding.Water glass solution alkalescence is very strong, pH typically between 10 ~ 12, so
PH during acidification reaction can through or close to pH corresponding to peak polymerization rate point.The silicic acid gel time near this pH
Be only several seconds the most shorter, if reaction medium can not moment quick hybrid reaction, not only can affect product quality, and easily
Generate silicic acid gel, cause W-response heterogeneity, make the product produced be difficult in rubber dispersion.
Summary of the invention
