Abstract

The invention discloses a preparation method for a high-friction oil strain-accommodating wiping material and belongs to the technical field of wiping material preparation. According to the preparation method, after purified algal cellulose is added into a precursor sol, the purified algal cellulose can slowly absorb water and swell; mullite whiskers can grow in the swelling purified algal cellulose during an ageing process; under high temperature, the instantaneous temperature on a friction surface is higher, and meanwhile, a softer material is generated and transferred to the friction surface of a harder material, so as to form a transferring film on the friction surface; yeast fermentation modification is adopted by the preparation method, and the blind holes and inner channels of the fiber sponge can be simultaneously opened by oily substances, such as a dimethyl silicone polymer, under the microbial action; the algal cellulose aerogel according to the invention has moderate pore size and high porosity; the wiping material provided by the invention comprises the main components as follows: plant cellulose, mountain flour sol and common nontoxic organic matters; a large amount of wastewater and slags are avoided in the production process; the preparation method has a wide application prospect.
