摘　　要：本文研究了醇酸清漆本征膜的紫外———可见吸收光谱特性、沥青的红外光谱和紫外———可见吸收光谱特性、C6 0 /C70 掺入醇酸清漆后所得薄膜的紫外———可见吸收光谱特性、沥青掺入醇酸清漆后所得薄膜的紫外———可见吸收光谱特性、C6 0 /C70 和沥青掺入醇酸清漆后所得薄膜的紫外———可见吸收光谱特性。实验证明 ,醇酸清漆对C6 0 /C70 具有很强的漂白作用 ,即醇酸清使C6 0 /C70 原紫外———可见吸收光谱的吸收峰消失 ,吸收曲线紫移 ,而对沥青吸收光谱则无影响。将C6 0 /C70 和沥青同时掺入醇酸清漆中 ,聚合后薄膜的吸光度在350～ 760nm波段随波长的增加而呈非线性下降 ,同时薄膜的强度也有所提高。This paper studied the characteristics of the UV-visible absorption spectra of alkyd varnish film, the characteristics of the IR absorption spectra and UV-visible absorption spectra of asphalt, and characteristics of UV-visible absorption spectra of film doped with C-60/C-70 and alkyd varnish, characteristics of UV-visible absorption spectra of C-60/C-70, and asphalt in the alkyd varnish. The experiments show that the alkyd varnish has bleaching effect on C-60/C-70, as spectral peak value of C-60/C-70 disappeared in the absorption curve, and the absorption curve shifted toward shorter wavelength, without affecting the a6gorption spectra of asphalt. Mingling C-60/C-70 and asphalt with alkyd varnish at the same time, the absorbance of the polymerization film decreased nontinearly with the increase in wavelength in the range of 350-760 nm, and also the strength of the film was improved.
