Abstract

The invention relates to outer bottom oil iron printing paint which comprises (a) bisphenol A, epoxy chloropropane and a catalyst; (b) an amino resin crosslinking agent; (c) solvent; and (d) wax powder, wherein the catalyst is a bisphenol A epoxy resin catalyst which is prepared from bisphenol A and epoxy chloropropane, the mass ratio of the bisphenol A to the epoxy chloropropane is (0.8-1.1):1, and the catalyst accounts for 0.8-4w%. According to the outer bottom oil iron printing paint provided by the invention, the curing time is short (only 25-120 seconds), and continuous printing and coating can be performed; and the intensity and adhesive force are high, thus ensuring that the invention is applicable to bottom oil coating and printing of outer iron printing.

Description

technical field [0001] The invention relates to an iron printing paint, in particular to an outer layer primer iron printing paint, which belongs to the technical field of can making. Background technique [0002] Tinplate, also known as tin-plated iron, is a common name for electroplated tin-plated steel sheet, and its English abbreviation is SPTE. It refers to cold-rolled low-carbon thin steel sheet or steel strip coated with commercial pure tin on both sides. Tin mainly plays the role of preventing corrosion and rust. It combines the strength and formability of steel with the corrosion resistance, solderability and beautiful appearance of tin in one material, which is corrosion-resistant, non-toxic and high-strength. , good ductility characteristics. Therefore, it is widely used in various fields such as packaging containers (canning, barrel making and food and beverage packaging), electronic products, household appliances, automobiles, motorcycles, etc. Of course, when ...
