| titleOfInvention | A kind of method of synthetic solvent type rare-earth rubber catalyst |
| abstract | A kind of method that the present invention relates to synthetic solvent type rare-earth rubber catalyst.The method, comprises the following steps: utilize neodymium oxide and the aqueous solution of hydrochloric acid preparation neodymium trichloride；Organic phosphoric acid and organic solvent are mixed to get organic phosphoric acid solution；Alkaline solution is added and obtains saponification liquor；With the viscosity of viscosity-controlling agent regulation lysate after dissolving completely；Carry out binary ageing respectively and ternary be aged, directly apply to the rare-earth catalysis system of rubber production.Preparation rare-earth rubber catalyst technical matters provided by the present invention is simple, low cost, and can the most arbitrarily regulate the viscosity of organic phosphoric acid neodymium.Additionally, use saturated alkane hexane in preparation process, it is to avoid use the organic solvent that environment can be polluted；The waste water main component produced in water-washing process is sodium chloride, after treatment can be with safety dumping；Technique introduces rectification water removal phase, can strictly control the water content in catalyst. |
