What is tinplate coating?
Canned containers made of tinplate usually need to be coated with a coating on the inner surface, the purpose of which is to prevent the chemical interaction between the contents of the can and the can wall and the contamination of the contents by trace amounts of harmful substances, and to protect the freshness of the contents as well as the original flavor, the starting food can be stored, transported and sold for a long time without affecting its edible value.
Composition of printed tinplate coatings
The tinplate coating is mainly composed of three major film-forming substances, secondary film-forming substances and auxiliary film-forming substances.
① The main film-forming substance. It is a basic substance that makes printed tinplate paint adhere to the surface of an object and form a film layer, also known as a fixing agent or an adhesive. It can form a film with strong adhesion alone, or it can form a film with a secondary film-forming substance, which plays a decisive role in the properties of coatings and films.
② Second film-forming substance. It can't be formed separately from the main film-forming substance. The secondary film-forming substance in the printing tinplate coating is pigment, which is mainly divided into color pigment, rust-proof pigment and physical pigment.
(A) Colored pigments. In printing tinplate coatings, colored pigments are mainly used for covering and decoration, and are the most common type of pigments. The main coloring pigment used in printing tinplate coatings is titanium dioxide, which is titanium dioxide.
(B) Anti-rust pigment. Its main function is to prevent metal substrates from being corroded. It is divided into physical antirust pigments and chemical antirust pigments. The former can increase the density of the film layer and isolate the metal surface from water, air, etc. Once the film layer is broken, the rust prevention fails. The latter mainly depends on the chemical passivation of the metal surface by the pigment to prevent rust. Even if the film is damaged by a small amount, it still has a certain ability to prevent rust.
(C) extender pigment. Also known as filler, it is generally a white powder. It has almost no coloring and covering ability to the film layer, but has good chemical resistance, abrasion resistance, and low price. It can be mixed with colored pigments to increase the thickness of the film layer and improve its mechanical properties.
③ auxiliary film-forming substance. This substance cannot form a film layer, it can only help to form a film layer and improve the performance of the film layer. The auxiliary film-forming substances include solvents and auxiliary agents with certain functions. Solvents in printed tinplate coatings include organic solvents, water, auxiliaries and diluents, which are necessary for the preparation of liquid coatings; the role of the additives is to improve the performance of a particular aspect of printed iron coatings, usually in small amounts, but with significant effects. Commonly used auxiliaries are plasticizer, matting agent, antistatic agent, drier, curing agent, leveling agent, anti-sagging agent, etc.
