Abstract

The invention discloses aqueous acrylic acid-modified alkyd resin and a preparation method thereof. Basic alkyd resin of the aqueous acrylic acid-modified alkyd resin is prepared from an unsaturated fatty acid, benzoic acid, trimethylolpropane, pentaerythritol, maleic anhydride, isophthalic acid, ethylene glycol monobutyl ether and butanol. The aqueous acrylic acid-modified alkyd resin is prepared by adding styrene, methyl methacrylate, butyl acrylate, acrylic acid, a silane coupling agent, benzoyl peroxide, tert-butyl hydroperoxide, ethylene glycol monobutyl ether and a mixing neutralizer into the basic alkyd resin. According to the aqueous acrylic acid-modified alkyd resin and the preparation method thereof, the advantages of alkyd resin and acrylic resin are integrated, and a product has high gloss retention, color retention and weather resistance; a production process is simple, the raw materials are readily available, and the production cost is low; a paint production process is simple, water is used as a diluting agent, and safety and convenience in construction are ensured.

Description

technical field

[0001] The invention relates to the field of synthesis of acrylic acid modified alkyd resin, in particular to a preparation method of waterborne acrylic acid modified alkyd resin. Background technique

[0002] With the continuous advancement of science and technology and the continuous enhancement of people's awareness of environmental protection, systems that contain no or less volatile organic compounds (VOC) and no harmful air pollutants (HAP) have become the development direction of new materials. Solvent-based systems are gradually being replaced by water-based systems, and the promotion of water-based environmentally friendly materials has become an inevitable trend. Therefore, the development of water-based resins has been paid more and more attention by people. At present, the most successfully developed varieties mainly include: water-based acrylic resins, water-based epoxy ester resins, and water-based alkyd resins.
