Preparation method and application of waste plastic derived TiC nano material

The invention belongs to the field of comprehensive utilization of waste plastics, and discloses a preparation method of a waste plastic derived TiC nano material, which comprises the following steps:S1, pulverizing waste plastics to 100-200 meshes; and S2, soaking the crushed waste plastic in an acid solution with a concentration of 1-2 mol/L for 1-3 h, then soaking the waste plastic in an alkali solution with a concentration of 1-2 mol/L for 10-14 h, and carrying out washing and drying for later use. According to the novel method for preparing the TiC nano material through the one-step chemical reaction under the relatively low temperature condition, production equipment needed by the production process of the method is simple, operation is easy, raw materials are rich in source and lowin price, industrial production is easy to achieve, preparation of the TiC nano material is achieved through simple product treatment in the later period, and the TiC nano material is used as a diaphragm modification layer to
