Abstract

The invention discloses aqueous dispersed alkyd blend colored paint and a preparation method thereof. The aqueous dispersed alkyd blend colored paint is made of, by weight, 40%-46% of alkyd resin, 2%-6% of petroleum resin, 10%-28% of color filler, 0.3%-0.8% of defoaming agent, 0.4%-0.8% of organic clay, 0.3%-0.6% of wetting agent, 0.5%-1% of drier, 0.1%-0.3% of anti-skinning agent, 20%-35% of cosolvent and 5%-10% of organic solvent. The aqueous dispersed alkyd blend colored paint is fresh and natural in smell and has excellent gloss, bonding force, flexibility, water resistance, corrosion resistance and outdoor durability.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-dispersible alkyd blend paint and a preparation method thereof. Background technique [0002] Alkyd resin is the most important resin for coatings, and it is also the largest and earliest synthetic resin used in the coatings industry. Most of the alkyd resins currently on trial are solvent-based resins, which are the main source of volatile organic compounds (VOC). With the gradual improvement of people's environmental requirements, countries have put forward strict restrictions on the content of VOC in coatings. Since water is non-toxic, odorless, non-flammable and cheap, introducing water into the paint can not only reduce the production cost, but also greatly reduce the VOC content. [0003] There are currently three methods of introducing water into an alkyd paint to form a dispersion: [0004] 1. Make the traditional alkyd resin contain excessive carboxyl groups, and neutr...
