Abstract

The invention discloses a solid thermoplastic acrylic resin special for PP (polypropylene), comprising the following components in percentage by mass: 35-45% of styrene, 15-25% of methyl methacrylate, 14-23% of vinyl acetate, 10-20% of high chlorinated polypropylene, 3-5% of high chlorinated polyvinyl resin, 0.7-1.2% of dibenzoyl peroxide and 0.7-1.2% of crylic acid. The invention also discloses a preparation method of the acrylic resin, comprising the steps of: heating proper deionized water to 75 DEG C and adding mixing monomer for polymerization, carrying out polymerization after heating the mixture to 88-95 DEG C and applying pressure to 0.5-1kg, reacting for 60min, finishing the polymerization at 108-112 DEG C, cooling after keeping temperature for 45min, discharging, dehydrating and drying. The solid thermoplastic acrylic resin can be directly prepared into printing ink and painting, reduce the construction difficulty and painting time, and has time and labor saving, low cost, good film-forming property and adhesion and high gloss.
