脲醛树脂在黑色喷漆中的应用

Application of Urea-formaldehyde Resin in Black Spraying Paint

研究脲醛树脂在黑色喷漆中的应用,以确定添加脲醛树脂是否会造成涂膜不干,并应用于指导高光喷漆的生产。探讨脲醛树脂对涂膜干燥时间、光泽度、附着力、硬度与抗发白性的影响。结果表明:在黑色喷漆中添加脲醛树脂可提高涂膜光泽度和丰满度,缩短涂膜的表干时间,改善涂膜附着力;脲醛树脂可有效地防止涂膜发白,其用量越大,防止涂膜发白的效果越显著。

Application of urea-formaldehyde resin is studied in black spraying paint to determine if the urea-formaldehyde resin could result in that the film is not dry. It provides references for the production of high gloss spraying paint. The effects of ureaformaldehyde resin on drying time, gloss, adhesion, hardness and whitening resistance are studied as well. The results show that: adding urea-formaldehyde resin in the black spraying paint can improve the gloss and fullness, shorten the film surface drying time and improve adhesion. It also indicates that the urea-formaldehyde resin can effectively prevent the whitening of the coating film, the more the dosage, and the better effect of whitening resistance.
