Abstract
P type zeolite detergent auxiliary agent preparation technology, utilize natural zeolite, through acid, alkaline purification it is modified as the P type zeolite with regular cube heart phase structure, can replace tri-polyphosphate to be used as detergent builder, its wash water residual phosphorus amount significantly reduces, prevented water pollution effectively, P type zeolite detergent auxiliary agent has very strong water softening performance and comprehensive soil removability.Its preparation technology is simple, the raw material cheapness, and the source is abundant, has reduced the production cost of washing composition, improves washing effect.
Description
The present invention is a kind of preparation technology of detergent builder.
Synthetic Detergent Auxiliaries adopts tripoly phosphate sodium STPP mostly, though tripoly phosphate sodium STPP has the general property of detergent builder, has residual phosphorus to exist in the wash water, be discharged into rivers and lakes after, algae is grown thickly, produce " crossing extensive use of chemical fertilizer " phenomenon, severe contamination water quality.The use synthesis of 4a zeolite that has at present is as the phosphoric acid salt surrogate, and the method that synthesis of 4a zeolite adopts usually has hydrothermal synthesis method, roasting kaolin method, acidic white earth method.Wherein hydrothermal synthesis method is to be raw material with water glass, hibbsite, sodium hydroxide and water, hibbsite, sodium hydroxide and water is mixed in the sodium aluminate reactor, reaction mixes with water glass (or silicon oxide), water, sodium hydroxide after finishing again, in amorphous silicon aluminium acid sodium reactor, react, obtain synthesis of 4a zeolite at last, because the synthesis of 4a zeolite cost is higher, therefore influenced applying of it.
The object of the invention is natural zeolite is carried out modification, makes the natural zeolite after the modification can be used as detergent builder, to the pollution problem of environment, reduces the production cost of washing composition when solving tripoly phosphate sodium STPP and making auxiliary agent.
P type zeolite detergent auxiliary agent preparation technology set forth in the present invention is through fragmentation with natural zeolite ore, in reactor, use mineral acid, example hydrochloric acid, sulfuric acid etc. were handled 4-16 hour, and treatment temp is controlled at 60-120 ℃, and inorganic acid concentration is 15-50%, natural zeolite modification after acid treatment becomes h-type zeolite, whiteness improves, and reactive behavior increases, and easily further modification becomes P type zeolite, then h-type zeolite and sodium hydroxide, sodium aluminate solution are mixed, ratio of component is: SiO
2/ Al
2O
3=4-10, Na
2O/SiO
2=0.4-0.8, H
2O/Na
2O=40-70, and kept 8-20 hour, h-type zeolite is modification again, the P type zeolite that crystallization becomes to have regular cube heart phase structure.
Preparation technology of the present invention is simple, and the natural zeolite after the modification can partly replace tripoly phosphate sodium STPP to make detergent builder.Adopt natural zeolite to make detergent builder, residual phosphorus amount significantly reduces in the wash water, prevents water pollution, and has higher water softening performance and comprehensive detergency ability.The present invention adopts natural zeolite to make raw material, the raw material cheapness, and the source is abundant.
It below is most preferred embodiment of the present invention.Natural zeolite ore through fragmentation, under 100-110 ℃ of temperature, was handled 6 hours with 30-40% sulfuric acid liquid, and the natural zeolite-h-type zeolite after filtration, washing acid are handled (contains Na with sodium hydroxide (concentration is 30%), sodium metaaluminate again
2The O2.1 mol contains Al
2O
31.3 mol) mixed, the control component ratio is: SiO
2/ Al
2O
3=5, Na
2O/SiO
2=0.5, H
2O/Na
2O=55, under 100 ℃ of temperature, crystallization 6 hours is filtered mixture, wash, dry at last, just obtains can be used as the P type zeolite of detergent builder.
