▎ 摘  要

NOVELTY - The transmission tower anticorrosive primer comprises 10-20 pts. wt. polyvinyl butyral, 0.1-2 pts. wt. graphene, 0.1-0.5 pt. wt. dispersant, 5-10 pts. wt. titanium dioxide, 2-5 pts. wt. talc powder, 10-20 pts. wt. strontium chrome yellow, 20-70 pts. wt. diluent and phosphoric acid curing agent. USE - Anticorrosive primer for corrosion protection of metal substrate of transmission tower, threaded fastener, steel or galvanized steel. ADVANTAGE - The anticorrosive primer has excellent substrate adhesion performance and comprehensive performance, and is prepared by simple process at low cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for (i)a preparation of transmission tower anticorrosive primer, which involves uniformly mixing dispersant, graphene, titanium dioxide and talc powder to obtain mixture (I), adding polyvinyl butyral, strontium chrome yellow and diluent, mixing to form mixture (II), mixing mixture (I) and mixture (II) and adding phosphoric acid curing agent to obtain final product.
