Embodiment 1
[0024] A kind of diesel oil filter paper, calculated in parts by weight: 50 parts of hardwood pulp, 15 parts of straw pulp, 15 parts of miscanthus pulp, 10 parts of carboxymethyl fiber, 20 parts of short silica fiber, 1 part of silica gel powder, zinc borate 0.5 parts, 40 parts of ethyl silicate, 5 parts of potassium permanganate, 30 parts of stearic acid modified liquid, and 80 parts of industrial methanol. Prepare target diesel oil filter paper according to the following steps:
[0025] a) Take hardwood pulp, rice straw pulp, miscanthus pulp, carboxymethyl fiber, and silica short fiber, pulp it through a pulper, and then refine it through a refiner, and the pulping degree is 15 degrees;
[0026] b) Take silica gel powder and zinc borate, place them in 5 parts of methanol for reaction, control the reaction temperature at 50±5°C, and the reaction time for 5-8 hours to obtain the coupling agent;
[0027] c) Add the coupling agent prepared in step b) to the slurry prepared in s...
