The invention relates to the technical field of preparation of highway maintenance materials and particularly relates to a preparation method of a modified phenolic resin based anti-glare panel. A pine chip is taken as the raw material, a phenolic resin is taken as a matrix, a modified self-made silica sol and a glass fiber are taken as modifying agents, and snail slime, coconut oil and the like are taken as the auxiliary materials to prepare the modified phenolic resin based anti-glare panel, one part of a group in a molecule of a silane coupling agent KH-560 and a group on the surface of a silica sol particle have condensation polymerization, the other part of the group and the phenolic resin have a chemical reaction or are physically wound, then the stress of an interface between the silica sol and the chemical reaction matrix is evener, the silicon dioxide in the silica sol and the hydroxyl in the phenolic resin have a crosslinking reaction, the corrosive materials like outside water and oxygen are effectively prevented from corroding and ageing the matrix, the fatty acid in the coconut oil is adsorbed on a corroded active point to prevent further corrosion and further improvethe corrosion resistance of the anti-glare panel, and the preparation method has a broad application prospect.
