Method for preparing novel super-waterproof filling material by using waste cloth

The invention discloses a method for preparing a novel super-waterproof filling material by using waste cloth. The method for preparing the novel super-waterproof filling material by using the waste cloth comprises the following steps that S1, the waste cloth is collected, and the waste cloth is cleaned and disinfected and dried for later use; S2, the disinfected and dried waste cloth is crushed and uniformly mixed; S3, the crushed and mixed cloth is soaked in a polyvinyl alcohol solution, a formaldehyde solution and a concentrated hydrochloric acid solution are added, uniformly stirred, and stood to obtain a high polymer; S4, residual reaction liquid adhered to the surface of the high polymer is washed off by using deionized water, and heated and oxidized in a high-temperature furnace; and S5, the oxidized high polymer is heated and cooled again, the high polymer is ground into powder to obtain a finished product material, and the finished product material is sealed and stored. According to the method for pr
