Aqueous printing ink for nonstick coat of cooking appliance

Abstract

The invention relates to an aqueous printing ink for a nonstick coat of a cooking appliance. The aqueous printing ink comprises the following components, by weight, 20-50 parts of a fluorine-containing emulsion, 1-40 parts of a pigment and 30-50 parts of deionized water, and further comprises 0.5-1 part of a defoamer, 0.5-1 part of an anti-flowering agent, and 4-8 parts of a tackifier. The invention also relates to the nonstick coat of the cooking appliance. The nonstick coat comprises a primary coat positioned on the substrate surface of the cooking appliance, an aqueous printing ink coat positioned on the primary coat, and a cover coat positioned on the aqueous printing ink coat. The aqueous printing ink of the invention can be used a solvent of a coating, has no volatility and is in favor of environmental protection; the high temperature resistance of the aqueous printing ink is good, so there is no yellowing of the aqueous printing ink after heating for 10min at 400DEG C; and the stability of the aqueous printing ink is good, so the demulsification is difficult during knife coating processing.

Description

technical field [0001] The invention relates to a water-based ink, in particular to a water-based ink used for non-stick coating of cooking utensils. Background technique [0002] Water-based ink, also known as water-based ink (referred to as water-based ink), is a printing ink that is made of water as the main solvent, a water-based binder formed from a water-based polymer compound, pigments and related additives through compounding and grinding. Water-based ink uses water as the main solvent, almost no volatile organic compound (VOC) emissions, no pollution to the atmosphere; water is the cheapest solvent, so the manufacturing cost of water-based ink is lower than any kind of printing ink, and has the advantage of low cost The manufacturing environment of water-based ink is safe, which ensures the health of operators, reduces resource consumption, and reduces environmental protection costs; water-based ink printing can reduce or even eliminate organic residues in printed m...
