The diatom mud patent introduces a preparation method of diatom mud building decoration materials, as follows: inventor (designer): Ji Hongjun; applicant (patent) person: Ji Hongjun; patent type: patent application date: 2015.10.13 public (Announcement) Date: Patent Number: 201510656089 Publication (Announcement) Number: Classification Number: C04B28/14(2006.01)I
A preparation method of diatom mud building decoration material, comprising the following steps:
Step 1: In sulfuric acid with a mass concentration of 70%, add butyl titanate, stir vigorously, slowly add zinc sulfate heptahydrate and calcium sulfate dihydrate, keep stirring vigorously, slowly add a small amount of water, and stir until the solution becomes transparent , to obtain solution A, wherein the molar ratio of sulfuric acid and butyl titanate is 3.5:1-4.5:1, the molar ratio of zinc sulfate to butyl titanate is 10%-20%, and the molar ratio of calcium sulfate to butyl titanate 5%‑10%;
Step 2: Add solution A to a certain amount of water, add a small amount of diatom mud, which accounts for 15%-25% of the mass ratio of butyl titanate, and stir to obtain solution B;
Step 3: Add the calcium hydroxide solution dropwise to solution B, adjust the pH value to neutral, and stir to obtain solution C;
The fourth step: filter the solution C to obtain the filter residue and dry it to obtain a solid compound D containing diatom mud, nano-TiO2, ZnO and CaSO4;
Step 5: Add solid D to the diatom mud, and stir and mix at a high speed to obtain a diatom mud building decoration material.
