Abstract

The invention relates to a method for spraying paint on a turned edge of a steel barrel. The method is characterized by comprising the following steps of: (1) outer surface treatment: preparing phosphorization solution from water, coating agent and degreasing cleaning agent in a weight ratio of 10-12: 0.3-0.4: 0.3-0.4, and uniformly wiping the phosphorization solution on the outer surface of the steel barrel on a barrel brushing machine; (2) pre-heating: placing the steel barrel wiped with the phosphorization solution on a production line of a drying passage for preheating, wherein the temperature of the drying passage is 60 to 70 DEG C, the length of the drying passage is 3 to 10 meters, and the conveying speed of the steel barrel is 2.8 to 3.7 meters per minute; (3) spraying: conveying the steel barrel to a paint spraying system and spraying the paint on the steel barrel; and (4) paint spraying on the turned edge: spraying the paint on the turned edge of the paint sprayed steel barrel by using a spray gun, wherein the steel barrel rotates uniformly when spraying the paint, and the rotating speed is 24 to 26 revolutions per minute. The degreasing cleaning agent is nonylphenol polyoxyethylene ether. The coating agent is phosphoric acid and / or phosphate. The method is convenient to operate and effective; and the paint on the turned edge of the steel barrel is attractive and has good adhesive force.

Description

technical field [0001] The invention relates to a paint spraying technology, in particular to a paint spraying method at the edge of a steel drum, and belongs to the field of steel drum manufacturing. Background technique [0002] With the development of global economic integration, the steel drum manufacturing industry, as a traditional industry, is used in more and more industries.
