环保型无甲醛涂料印花遮盖白浆的研究

Study of the Eco-friendly Formaldehyde-free Covering White Paste for Pigment Printing

将具有自主知识产权的无甲醛粘合荆、螯合分散稳定剂与抗凝胶荆、钛白粉、乳化荆、柔软剂、保湿荆等按一定比例混匀后，先经高速乳化，再经三辊机研磨，均质机均质，得到一种细度细、质地均匀的白色细腻膏状遮盖白浆产品。该遮盖白浆具有不含甲醛、遮盖力强、色牢度好、不堵网、可用合成增稠剂增稠等优点，可在140－160℃焙烘2～3n／n的条件下用于棉、麻、丝绸、涤纶及腈纶等各类纤维及其混纺或交织物的有色或白色织物上罩印白色花纹，还可加入一定量的有色涂料作为有色织物上的各种彩色罩印印花，印花织物的各项色牢度均达到或超过国家标准。

The eco-friendly formaldehyde-free printing covering white paste with independent intellectual property of good fineness and uniform texture was prepared through several processes, such as well mixed in certain ratio of formaldehyde-free adhesive and chelating dispersant with anticoagulant, titanium powder, emulsifier, softener, humectant, emulsified by high-speed disperse mill, grinded in three rollers machine and homogenized by homogenizer. The covering white paste had the properties of formaldehyde-free, strong covering power, good color fastness, non blocking network and could be used with synthetic thickener. The covering white pulp could be used to print white pattern and various colored patterns by adding a certain amount of the colored pigments for cotton, linen, silk, polyester, acrylic and other kinds of fiber under the temperature of 140;160℃, baking time of 2;3 min.The color fastness of printed fabric reached or exceeded the national standard.
