Abstract

The invention relates to a compound drier emulsion which has a 'nuclear-shell' structure and is used for a waterborne air-drying coating, which is characterized in that the compound drier emulsion is the purple emulsion containing various metal ingredients, which takes an organic metal soap as a 'nuclear', takes a reactive non-migrant surfactant as a 'shell' and is compounded by being matched with a special emulsifier, and the solid content is 45 to 72 percent by weight. The compound drier emulsion can ensure the stability of the coating and the effectiveness of the drier, reduce the defects of a paint film and improve the gloss of the paint film by being used for the waterborne air-drying coating.

Description

technical field [0001] The invention relates to the paint industry in the field of chemical industry, in particular to the compounding of an important compounding agent for an environment-friendly water-based paint, that is, the compounding of a drier and its preparation method. Background technique [0002] In the German standard DIN55901, the drier is defined as follows: "The drier, also known as the dry material in the solution state, is an organometallic compound that can be dissolved in organic solvents and resins. From a chemical point of view, it Belonging to metal soaps, when added to unsaturated oils and resins, the drying time can be greatly shortened, that is, the curing speed can be accelerated." [0003] At present, driers are generally divided into the following categories: [0004] 1. Main drier: They are generally metal soaps containing multiple oxidation valence states, which can undergo redox reactions. Commonly used driers of this type in the industry ar...
