以空心塑性颜料与钛白粉作为功能性颜料,通过配比,以颜料总的固含量占5%加入到涂料中。通过对涂布纸的白度、平滑度和光泽度的测定,研究了这两种功能性颜料对涂布纸纸张性能的影响。研究发现:当空心塑性颜料的加入量大于钛白粉时,涂布纸的白度和光泽度明显具有优势随着空心塑性颜料的加入量减少,钛白粉的加入量增多,涂布纸的白度与光泽度随之下降。涂布纸的平滑度虽然没有递增或递减的趋势,但当空心塑性颜料为3%,钛白粉为2%时,涂布纸具有最大的平滑度
To hollow plastic pigment and titanium dioxide as a functional pigment, through the ratio of total solid pigment content of 5% added to the paint. By measuring the whiteness, smoothness and gloss of the coated paper, the effect of the two functional pigments on the properties of coated paper was studied. It is found that the whiteness and gloss of the coated paper have obvious advantages when the content of the hollow plastic pigment is larger than that of the titanium dioxide. As the addition of the hollow plastic pigment decreases, the amount of the titanium dioxide increases, the whiteness of the coated paper With the gloss decreases. The smoothness of the coated paper, although there is no trend of increasing or decreasing, but when the hollow plastic pigment is 3%, titanium dioxide is 2%, the coated paper has the greatest smoothness
