Abstract
The invention discloses a composition containing polyether refined adsorbent slag and application thereof in cement grinding process, belonging to the technical field of cement grinding process additives. The composition consists of polyether refined adsorbent slag and alcohol amine-containing cement grinding aid, wherein the mass ratio of the polyether refined adsorbent slag to the alcohol amine-containing cement grinding aid is 10-40:1; the polyether refined adsorbent slag is generated in the polyether polyol refining process. The invention applies the composition of the polyether refined adsorbent slag and the alcohol amine-containing cement grinding aid in the cement grinding process, and compared with the independent application of the adsorbent slag or the alcohol amine-containing cement grinding aid, the invention obviously improves the compressive strength of cement and improves the quality of cement.
Description
Technical Field
The invention belongs to the technical field of cement grinding process additives, and particularly relates to a composition containing polyether refined adsorbent slag and application of the composition in cement grinding process.
Background
Magnesium silicate is a silicate consisting of silicon oxygen tetrahedra and magnesium oxygen octahedra. The magnesium silicate adsorbent is artificially synthesized magnesium silicate with a porous structure and is widely applied to organic matter refining. The magnesium silicate adsorbent is a porous material with high specific surface area, and has good heat stability, salt resistance, corrosion resistance, acid and alkali resistance and radiation resistance. Has cation exchange property and is an adsorption material with excellent performance.
The magnesium silicate adsorbent is an inorganic adsorbent for refining polyether polyol and is used for removing potassium and sodium ions, pigments and impurities in crude polyether polyol. The main quality index of the polyether polyol is determined: moisture, acid value, K + 、Na + Content, chromaticity. The polyether polyol is prepared by reacting alkali metal ions serving as a catalyst, polyol or amine serving as an initiator with alkylene oxide at a certain temperature and under a certain pressure. Adding magnesium silicate adsorbent into crude polyether polyol to remove residual catalyst, reducing chromaticity, filtering to obtain filtrate which is polyether polyol, and filtering residues which are polyether refined adsorbent residues containing polyether polyol.
The main components of the filter residue are as follows: magnesium silicate adsorbent, residual catalyst (mainly potassium hydroxide or potassium salt), polyether polyol, and small amount of water. The filter residue is generally treated by the following ways:
firstly, the solid waste treatment is entrusted to a third party, payment treatment is generally carried out by adopting incineration, and gas is discharged into the atmosphere, so that the atmospheric environment is negatively affected; the solid residue is mainly magnesium silicate, and the potassium sodium salt is auxiliary, and is used as solid filler or is used as solid waste for landfill, so that the earth environment is negatively affected to a certain extent.
And secondly, recycling. Washing the filter residues with a solvent, eluting residual polyether polyol, removing the solvent, recycling the polyether polyol, utilizing the residual secondary waste residues as solid waste treatment, and entrusting a third party for payment treatment. The solvent used may be a polar solvent or water. If polar solvent is used, polyether polyol is washed out, the removed solvent needs to be treated after the solvent is removed, and the amount of the solvent is generally larger, so that new cost is caused; if the solvent is water, the polyether polyol and potassium sodium alkali salt are simultaneously washed out, the potassium sodium ion content of the polyether polyol is high, the requirement of recycling quality index cannot be met, the non-aqueous solvent is required to be used for extraction and separation, and finally, the non-aqueous solvent is required to be removed, so that new cost is caused.
The polyether refining adsorbent slag containing the polyether polyol generated after the polyether polyol is refined requires environmental protection cost and larger economic cost no matter which method is adopted. Not only causes environmental pressure, but also causes resource waste.
In view of the above, the treatment of polyether-refined adsorbent residues containing polyether polyols is an industrial challenge.
