The invention belongs to the technical field of chemical materials and relates to a method for preparing high-hardness alkyd resin resistant to acid corrosion. The method includes steps: heating organic silane, ethyl alcohol and hydrochloric acid, dissolving organic silane into alcohol, and adding methyl methacrylate to enable mutual dissolution of organic silane and methyl methacrylate, so that aSi-O bond and a Si-C bond are introduced into organics, and molecular cross-linking intensity of alkyd resin is enhanced. Soybeans are subjected to grinding and boiling to extract a protein componentin the soybeans, pepsase and alanine aminotransferase are sequentially added to generate amino acids through proteolysis, pepsase preliminarily decomposes protein to enable peptide chain breakage, alanine aminotransferase is superior in peptide chain decomposing performance, and amino groups in the resin material are increased. In a reaction process, intermolecular hydrogen bond adsorption is enhanced through hydrogen ato
