Abstract

The invention relates to a tripolyindanone derivative modified water-based acrylic resin and a preparation method thereof. The resin is prepared from the following components in parts by weight: 1.5 to 4.5 parts of indanone derivative, 3.0 to 11.0 parts of isophorone diisocyanate, 0.5 to 1.2 parts of hydroxyethyl acrylate, 0.1 to 0.6 part of benzoyl peroxide, 2.0 to 5.0 parts of acrylic acid, 30.0 to 70.0 parts of acrylate hard monomer, 40.0 to 85.0 parts of acrylate soft monomer, 3.0 to 8.0 parts of allyl glycidyl ether, 12.0 to 35.0 parts of cosolvent, 5.0 to 10.0 parts of N-methylpyrrolidone, 1.8 to 7.5 parts of a neutralizer and 100.0 to 200.0 parts of deionized water. The prepared indanone derivative modified water-based acrylic resin has a series of functions of good artificial aging resistance, salt fog resistance, good fluorescence property and the like, and when the resin is prepared into water-based paint, an antibacterial agent does not need to be added, and the water-based paint has good antibacterial and bactericidal functions.

Description

technical field [0001] The invention relates to a modified water-based acrylic resin, in particular to a terindone derivative modified water-based acrylic resin and a preparation method thereof, belonging to the technical field of synthesizing water-based functional resins. Background technique [0002] Water-based acrylic resin has the advantages of good color retention, gloss retention, weather resistance, and alkali resistance. Moreover, there are a wide variety of raw materials, large options, and relatively cheap prices. Therefore, water-based coatings prepared from acrylates are widely used in many fields such as construction, leather, paper, metal anticorrosion, wood, and plastics. Compared with acrylic resin, some properties of water-based acrylic resin are not perfect, and these shortcomings of water-based acrylic resin seriously restrict its application and development. [0003] In addition to reducing the volatilization of organic compounds, as the needs of moder...
