Embodiment 1
[0026] The preparation method of the sponge formed by the interlocking of porous mesh material and polyvinyl alcohol porous foam, its specific manufacturing steps are as follows: first, 6% polyvinyl alcohol and water are mixed to form a polyvinyl alcohol aqueous solution, and the After it is heated to 70°C, it is kept at a constant temperature; 4% starch mixed with water is used as a pore-forming agent for the sponge, added to the above-mentioned polyvinyl alcohol aqueous solution, and quickly stirred and mixed evenly; it will account for 0.3% of the total weight of the formula The tributyl fat is used as the defoaming agent of the sponge, is added in the above-mentioned aqueous solution of polyvinyl alcohol, and after stirring evenly, the solution is gradually cooled to 50°C; the formaldehyde solution accounting for 8% of the total weight of the formula is used as the cross-linking agent of the sponge, Add it into the above-mentioned polyvinyl alcohol aqueous solution, and sti...
Embodiment 2
[0028] The preparation method of the sponge formed by the interlocking of porous mesh material and polyvinyl alcohol porous foam, its specific manufacturing steps are as follows: first, 5% polyvinyl alcohol and water are mixed to form a polyvinyl alcohol aqueous solution, and the After it is heated to 68°C, it is kept at a constant temperature; 2% of starch mixed with water is used as a pore-forming agent for the sponge, added to the above-mentioned polyvinyl alcohol aqueous solution, and quickly stirred and mixed evenly; it will account for 0.3% of the total weight of the formula The tributyl fat is used as the defoamer of the sponge, and is added into the above-mentioned polyvinyl alcohol aqueous solution, and the solution is gradually cooled to 45°C after stirring evenly; the formaldehyde solution accounting for 6% of the total weight of the formula is used as the cross-linking agent of the sponge, and added into the above-mentioned polyvinyl alcohol aqueous solution, and qu...
