Abstract

The invention relates to a tripolyindanone derivative modified waterborne alkyd resin and a preparation method of the tripolyindanone derivative modified waterborne alkyd resin. The invention relates to a water-based paint, which is prepared from the following ingredients in parts by weight: 20.0 to 45.0 parts of vegetable oleic acid, 1.0 to 4.0 parts of truxene derivatives, 3.0 to 6.0 parts of cyclohexanediol monoacrylate, 18.0 to 35.0 parts of polybasic acid, 15.0 to 40.0 parts of polyhydric alcohols, 10.0 to 20.0 parts of xylene, 2.0 to 6.0 parts of tris (4-carboxyl biphenyl) amine, 8.0 to 15.0 parts of mixed liquor, 2.0 to 5.0 parts of benzoic acid, 2.5 to 6.0 parts of dimethylolpropionic acid, 3.0 to 10.0 parts of a neutralizing agent and 100.0 to 200.0 parts of deionized water. the prepared tripolyindanone derivative modified waterborne alkyd resin is connected with a tripolyindanone derivative through a chemical bond on the structure of alkyd resin, and the performance is stable; the composite material not only has the characteristics of the indanone, but also has the characteristics of the Schiff base, and has good antibacterial and bactericidal functions; and the prepared coating does not need additional bactericides, can be used for water-based building coatings, water-based wood coatings, water-based special coatings and the like, and has very huge application potential.

Description

technical field [0001] The invention relates to a modified alkyd resin, in particular to a terindone derivative modified water-based alkyd resin and a preparation method thereof, belonging to the technical field of water-based functional resin synthesis. Background technique [0002] Alkyd resin is an important resin for coatings. It has rich sources of monomers, low price, many varieties, large formula changes, convenient chemical modification and good performance. Alkyd coatings also have good workability and high film fullness. , good flexibility and other characteristics, widely used in decoration and protection of steel structures. Its easy construction and cross-linking properties with oxygen make it self-drying and versatile and widely used. Therefore, since the development of alkyd resin, alkyd resin has always occupied an important position in the coating industry, but traditional alkyd resin has certain limitations in some special fields. [0003] Triindene has a...
