Title:
NEW METHOD FOR PREPARING CARBON-BASED SHAPED ENGINE OIL PURIFICATION MATERIAL FOR VEHICLES AND SHIPS
Document Type and Number:
WIPO Patent Application WO/2023/185249
Kind Code:
A1
Abstract:
Disclosed in the present invention is a new method for preparing a carbon-based shaped engine oil purification material for vehicles and ships, which belongs to the technical fields of application of activated carbon materials and engine oil filtration. The method comprises: mixing a carbonaceous adsorption material having a special microstructure with a macromolecular adhesive at a certain ratio until uniform, and curing and forming same to prepare a carbon-based shaped engine oil purification material having a unique net-shaped structure for vehicles and ships. By regulating and controlling the microstructure and surface characteristics of the carbonaceous adsorption material, the purification material is more suitable for removing impurities in engine oil, and the dirt containing capacity and purification effect thereof are improved. By means of a molecular chain reaction of a resin adhesive, a polymer adhesive having a three-dimensional structure is formed, such that the oil resistance, the high-temperature resistance and the bonding strength are improved, and an open-cell type permeable adhesive film is formed and does not block the original pore structure of the adsorption material, thereby maintaining a good adsorption performance. By means of the coupling of the materials and the process, a unique net-shaped structure is formed; therefore, the purification material adapts to the large-throughput flow velocity of engine oil for vehicles and ships, the filtering effect of a woven net-channel structure and the adsorption effect of pore channels of the carbonaceous adsorption material are given to play, and the performance of purifying engine oil is improved.
