Aqueous chlorinated polypropylene-modified acrylic resin for PP (polypropylene) plastic coating and preparation method as well as paint and preparation method of paint

The invention relates to aqueous chlorinated polypropylene-modified acrylic resin for PP (polypropylene) plastic coating and a preparation method as well as paint and a preparation method of the paint, wherein the resin comprises the following ingredients in percentage by weight: 2.5-5% of an emulsifying agent, 58-65% of deionized water, 0.2-0.3% of an initiator, 0.1-0.2% of a pH buffering agent,29-35% of acrylic monomer mixture, 2-5% of chlorinated polypropylene resin and 0.2-0.5% of a neutralizing agent. The aqueous chlorinated polypropylene-modified acrylic resin has the advantages that the preparation method is simple and practicable, the cost is low, and the prepared paint not only has excellent adhesive force on a polypropylene material and weather resistance but also has excellentadhesive force on composite materials such as ABS (acrylonitrile butadiene styrene), polyethylene and polyvinyl chloride simultaneously. 一种用于PP塑料涂装的水性氯化聚丙烯改性丙烯酸树脂及制备方法、涂料及涂料制备方法，其中树脂包括以下重量百分比含量的组分，乳化剂2.5-5%；去离子水58-65%；引发剂0.2-0
