Environment-friendly waterproof coating method superior in heat insulation and insulation

摘要

The present invention relates to an environment-friendly polyurea resin film coating method exhibiting superior heat blocking and insulation properties. More specifically, the present invention relates to an environment-friendly polyurea resin film coating method exhibiting superior heat blocking and insulation properties as well as adhesion force, tensile strength, and waterproof performance by adding functional powder. The polyurea resin film coating method of the present invention includes: a step of forming a primer layer on the bottom of an object to be coated; a step of applying a first waterproof composition containing a polyurea resin and first functional powder on the primer layer to form a middle coating layer; and a step of applying a second waterproof composition containing methyl methacrylate and second functional powder on the middle coating layer to form a top coating layer.
