Abstract

The invention discloses graphene-doped large-contact-area dual-layer composite fuel oil filter paper and a preparation method thereof. The filter paper is characterized by being prepared from, by weight, 2-4 parts of graphene, 10-20 parts of hardwood pulp fibers, 1-2 parts of bentonite, 10-20 parts of coniferous pine pulp fibers, 10-20 parts of polyester fibers, 10-20 parts of sepiolite nanofibers, 1-2 parts of citric acid, 3-5 parts of Fe2O3, 5-10 parts of TiO2, 4-8 parts of MgO, 25-35 parts of a silane coupling agent KH560, 15-20 parts of a polyoxyethylene aqueous solution, 2-4 parts of a titanate coupling agent DNZ201, 50-60 parts of isopropanol, 5-10 parts of styrene-acrylic emulsion and an appropriate amount of polyacrylate emulsion. According to the filter paper, gaps among layers are improved, the obvious porosity gradient is retained, and the filter efficiency is improved; by conducting creasing treatment on the filter paper, the contact area of fuel oil and the filter paper is increased, and then the filter efficiency is further improved; by cooperatively adding the graphene, the glossiness and the tensile property of the filter paper are improved.

Description

Problems solved by technology

[0004] In Li Yanxia's "Design of Organic-Inorganic Composite Filter Material", a single-layer organic-inorganic composite filter material was synthesized by using wood pulp and synthetic fibers. The gradient of pores is not obvious enough, and the filtration accuracy is not good. There is also room for improvement in strength and fire resistance
