Abstract

The invention relates to an amino baking varnish, in particular to an amino baking varnish for a galvanized pipe and a preparation method of the amino baking varnish. The amino baking varnish comprises resin, a conventional auxiliary agent, a film forming auxiliary agent, an anti-settling agent, a thickener, deionized water, a functional auxiliary agent, a dispersing agent, a coloring pigment, ananti-rust material, methyl etherified amino resin, an amine neutralizing agent, a leveling agent and a wetting agent. According the amino baking varnish, adhesion is excellent, the crosslink density of the amino resin can be enhanced by adding enclosed isocyanate, the adhesion with a base material is enhanced, oxidation and rust of the galvanized pipe are prevented, the preparation process is simple, the operation is convenient, the production cost is saved, and manpower and material resources are saved.

Description

technical field [0001] The invention relates to a coating, in particular to an amino baking varnish for galvanized pipes and a preparation method thereof. Background technique [0002] Galvanized pipe is a welded steel pipe with a hot-dip or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially offshore oil fields, and oil heaters and condensation pipes for chemical coking equipment. Pipes for coolers, coal distillation washing oil exchangers, trestle piles, and support pipes for mine tunnels, etc. [0003] The use of galvanized pipes The iron pipes used for gas and heating are also galvanized pipes. Galvanized pipes are used as water pipes. After several years o...
