【摘要】 通过接枝共聚的方法合成了SBS改性丙烯酸树脂,并以此为基料制备了铝合金阳极化保护涂料。考察了SBS用量、不同单体用量和引发剂用量对树脂性能的影响。红外光谱分析表明SBS和丙烯酸成功进行了反应。通过改性丙烯酸涂料的冲击强度从原来的30kg·cm提高到50kg·cm,耐磨性提高了20%,拉伸强度提高了800%。更多还原

【Abstract】 SBS modified acrylic resin was prapared by craft copolymeration, and protecting coatings for anodic process of aluminum alloy was prapared. The influences of the amount of SBS, different monomers, in to the performances of acrylic resin was discussed. Analysis by IR spectrum has shown that SBS is successfully reacted with acrylic resin. As a result, impact strength of acrylic resin is increase to 50 kg·cm from 30 kg·cm, anti-abrasion is increase by 20%, and strain strength is increased by 800%.更多还原
