Background
The sticky wiping cloth is widely applied to dust removal and oil stain removal before painting of paint in automobiles and motorcycles or finish paint, dust removal before painting of pianos, cleaning before painting in coating lines of engineering machinery and dust removal of the front surface of high-grade furniture as a cleaning material with excellent dust removal performance. It consists of two parts, non-woven fabric and adhesive attached to the non-woven fabric. At present, the adhesive wiping cloth which is most widely used in China is mainly prepared by two technical processes. The first technique is to dissolve long oil alkyd resin as adhesive in organic solvent such as ethyl acetate and butanone, then dip the non-woven fabric in the organic solvent for a certain time, extrude the surplus solution from the non-woven fabric, and dry the solvent to obtain the adhesive wiping cloth. The second technique is to dip the non-woven fabric into a mixed aqueous solution in which a pressure-sensitive adhesive, a tackifying resin and a slipping agent are dissolved, extrude the excess solution, and dry to obtain the viscous wiping cloth. Obviously, the organic solvent used in the first technology can cause great damage to the environment and operators, and does not meet the requirement of the development of green environmental protection times. In the second technique, a large amount of organic small molecular substances are used, and the small molecular substances escape to enter the user body through the skin to cause harm to the human body and pollute the environment. At present, the increasingly serious environmental protection problem is faced, and the wiping cloth which is green and environment-friendly and has excellent dust removal performance is urgently needed.
