Embodiment 1
[0056] 1. Prepare the materials according to the following mass ratio, and the chemical reagents are all analytically pure:
[0057]
[0058] 2. Product preparation:
[0059] Step 1. Mix 12 parts of phosphoric acid with 12 parts of deionized water, wait to be cooled, and set aside.
[0060] Step 2. Put 62 parts of deionized water into a beaker, and use SWFS-400 laboratory high-speed disperser to stir. The stirring speed is set to 600r / min. Under the stirring state, the zinc dihydrogen phosphate and zinc oxide are proportioned. , Potassium chlorate, sodium molybdate, sodium fluoride, sodium benzoate, citric acid, oxalic acid, thiourea, triethanolamine, OP-10 were added in sequence, stirred for 30 minutes, then added the phosphoric acid prepared in step 1, and continue to stir for 30 minutes. The product is obtained when the solution is transparent and free of impurities.
[0061] 3. Performance test:
[0062] Perform performance tests on the prepared products, and the data is as follow...
Embodiment 2
[0074] Phosphoric acid: 15 parts
[0075] Deionized water: 71 parts
[0076] Others are the same as the first embodiment.
