硝基快干汽车修补漆的制备

Preparation of quick-dry nitro coatings for automobile repair

通过试验,用1/2s硝酸纤维素溶液和热塑性丙烯酸树脂制备硝基快干汽车修补漆,讨论了二者比例、氨基树脂、增塑剂和有机溶剂等对涂料性能的影响。结果表明,当1/2s硝酸纤维素溶液和热塑性丙烯酸树脂比例为38∶39,丁基化三聚氰胺甲醛树脂添加量为4.5%,邻苯二甲酸二丁酯添加量为3%,有机溶剂选择恰当时,该硝基涂料的综合性能良好。

The quick-dry nitro coatings for automobile repair are prepared through experiments, 1/2 s cellulose nitrate solution and thermoplastic acrylic resin used as binders. The paper discusses the influence of ratio of the two binders, amino resin, plasticizer and organic solvent on coatings performance, resulting that with the ratio of 1/2 s cellulose nitrate solution and plastic acrylic resin being 38：39, adding amount of butylated melamine formaldehyde resin being 4.5%, adding amount of di-n-butyl phthalate being 3% and suitable solvent, nitro coatings of good integrated performance can be prepared.
