Abstract

The invention discloses waterborne acrylic acid modified alkyd resin and a preparation method. The waterborne acrylic acid modified alkyd resin is prepared from the following raw materials: 22 to 24 percent of dry or semi-dry plant oleic acid, 14 to 15 percent of tribasic alcohol with a side chain, 13 to 14 percent of phthalic anhydride, 0.05 to 0.15 percent of a color reduction agent, 1 to 3 percent of refluxing xylol, 0.7 to 1 percent of cis-butenedioic anhydride, 2.5 to 2.7 percent of trimellitic anhydride, 4 to 5 percent of methyl methacrylate, 6 to 8 percent of styrene, 1 to 2 percent ofbutyl acrylate, 0.5 to 1 percent of an initiator and 28 to 29 percent of propylene glycol methyl ether. The waterborne acrylic acid modified alkyd resin is obtained by combining the above preferable raw materials; the waterborne acrylic acid modified alkyd resin has good environment protection performance and low toxicity, also keeps excellent comprehensive performance including glossiness, adhesion and, rigidity and the like and has very good technical effects.

Description

technical field [0001] The invention relates to a resin, in particular to a water-based acrylic-modified alkyd resin with environmental protection, low toxicity, and excellent performances such as gloss, adhesion, and hardness, and belongs to the technical field of polymer materials. Background technique [0002] Acrylic modified alkyd resin not only has the advantages of good fullness of self-drying alkyd resin, easy brushing of paint, good wettability to pigments, etc., but also has fast drying, high hardness, gloss and color retention of acrylic resin Good and other advantages, it is the first resin for outdoor anti-corrosion paint. However, with the strengthening of people's awareness of environmental protection and the country's control of VOC (volatile organic compounds) in coatings, it is imperative to make acrylic modified alkyd resins water-based. [0003] Although water-based acrylic modified resins have been developed at present, the current water-based acrylic m...
