Abstract

The invention discloses a modified polyurethane-acrylate water-based woodware emulsion and a preparation method thereof. The modified polyurethane-acrylate water-based woodware emulsion is mainly prepared from, by mass, 8.2-9.1 parts of isophorone diisocyanate (IPDI), 5.6-6.1 parts of polycaprolactone dihydric alcohol (PCL), 1.1-1.4 parts of dihydroxymethyl butyric acid (DMBA), 0.1-0.4 part of trimethylolpropane (TMP), 0.3-0.5 part of hydroxyethyl methacrylate (HEMA), 0.77-0.8 part of triethylamine (TEA), 8.4-9.5 parts of methyl methacrylate (MMA), 7.9-10.6 parts of acrylic monomer (BA), 0.76-1.55 parts of methylacrylate water glyceride (GMA), 1.085-2.03 parts of epoxy resin, 0.18-0.2 part of silane coupling agent, 58.84-64.38 parts of water and 0.09-0.11 part of initiator. The emulsion prepared by the method is good in performance.

Description

technical field [0001] The invention relates to a modified polyurethane-acrylate water-based woodware emulsion and a preparation method thereof, which can be used for water-based woodware paint and woodware coating. Background technique [0002] Environmental protection and energy are two major challenges we face in the 2l century. In order to meet this challenge, the wood coating industry is gradually changing from traditional solvent-based coatings with high energy consumption and high pollution to environmentally friendly and resource-saving water-based coatings. In recent years, in order to curb the pollution caused by solvent-based wood coatings on a large scale in my country, my country imposed a consumption tax on solvent-based coatings from February 1, 2015, further reducing the market for oil-based coatings. In the first half of 2015, the output of my country's wood-based panels reached 144 million m3, and the output of furniture reached 374 million pieces. my coun...
