The invention discloses a high-density long-acting anticorrosive coating suitable for a heating surface of a biomass boiler. The high-density long-acting anticorrosive coating is formed by coating the following raw materials in percentage by mass: 10-20% of high-melting-point rare metal powder; 5%-7% of aluminum silicon powder; 12%-16% of rare earth; 8%-10% of high-temperature-resistant fibers; 11%-17% of an inorganic coating; and 20%-30% of a high temperature resistant inorganic nano composite adhesive. The high-temperature-resistant inorganic nano-composite adhesive is prepared from inorganic nano-materials through condensation polymerization, and the high-temperature-resistant inorganic nano-composite adhesive is a neutral suspension dispersion system with the PH value. The aluminum-silicon powder is a compound composition of magnesium silicate and aluminum silicate, the structure of the aluminum-silicon powder is a chain layer flaky crystal form transparent body, the density is 2.7-2.9, and the hardness i
