The invention discloses inner-wall paint for liquid-food can with high-temperature resistant sterilization. The paint is prepared from the following compositions: modified polyester resin, ethyl acrylate, shellac resin, starch gel powder, stuffing, adjuvant, and solvent. Compared with other existing inner-wall paint for liquid-food can, the present inner-wall paint for liquid-food can is capable of greatly enhancing the storage stability of canned food. The paint film has long life, and is 2-3 times higher than the life of normal canned food inner-wall paint. The paint layer formed after coatings of the inner-wall paint for canned food is firm, with greater brightness, strong adhesion, acid resistant, sulfur resistant, strong salt resistant, stable in functionality, hard to be corroded, and non-discoloring. The present paint has good high-temperature resistant ability and sterilization ability; it can adapt to most of the high-temperature sterilizations at different temperature levels on the market; meanwhile the paint is not harmful to environment, does no harm to human bodies, and is beneficial for green environmental protection.
