Abstract

The invention discloses a water-based acrylic modified alkyd resin and a preparation method thereof. It consists of 22-24% dry or semi-dry vegetable oleic acid, 14-15% trihydric alcohol with side chains, 13-14% phthalic anhydride, 0.05‑0.15% color reducer, 1‑3% reflux xylene, 0.7‑1% maleic anhydride, 2.5‑2.7% trimellitic anhydride, 4‑5% methyl methacrylate, 6‑8% styrene, 1 ‑2% butyl acrylate, 0.5‑1% initiator, 28‑29% propylene glycol methyl ether. The present invention uses the combination of the above preferred raw materials to obtain the water-based acrylic modified alkyd resin, which not only has good environmental protection and low toxicity, but also maintains excellent comprehensive properties such as gloss, adhesion and hardness, and has achieved 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...
