Abstract

The invention discloses a water-borne alkyd resin paint additive, which comprises the following components: trimethylolpropane, pentaerythritol, ethylene glycol monobutyl ether, sorbic acid, an abietic acid solution, sodium pyrophosphate, an anti-sedimentation agent, and an infiltration dispersant. in consideration of the problems of water-borne alkyd resin in use, the invention provides the additive applicable to water-borne alkyd resin paint, and solves the problems of easy sedimentation and influence on corrosion and rust protection functions of metals in the use process of water-borne alkyd resin paint.

Description

technical field [0001] The invention belongs to the field of paint additives, and in particular relates to a water-soluble alkyd resin paint additive, a preparation method and a use method of the additive. Background technique [0002] With the enhancement of people's awareness of environmental protection, the coating industry is gradually moving towards water-based, high-solid and UV curing to reduce the amount of solvent used, especially the improvement of resin water-based technology. In recent years, water-based coatings have been gradually used in industrial production. in multiple fields. Water-based alkyd resin is one of the important members of the water-based paint family. The monomer of alkyd resin is easy to get, low in price, and has many varieties. Moreover, alkyd resin has good comprehensive performance and high cost performance. It is one of the first-choice paints in the market. Waterborne alkyd resin coating is the future direction of alkyd resin coating de...
