Multifunctional wood protection agent based on nano silica sol and preparation method of multifunctional wood protection agent

[0028] (1) get concentration 20%, alkaline silica sol 352g, potassium carbonate 14g, borax 12g, manganese chloride 20g, phosphoric acid 6g of particle diameter<20nm;

[0029] (2) add salt of wormwood to silica sol, keep stirring during adding, until salt of salt dissolves completely, then add borax, after adding borax, add phosphoric acid while stirring, until borax dissolves completely;

[0030] (3) After the borax is completely dissolved, add manganese chloride, which is now called current use and kept dry before use;

[0031] (4) Stir the finally obtained mixed solution for 30 min to obtain.
