Abstract

The invention discloses a method for producing a thermal-insulation and formaldehyde-adsorption wallpaper by using a spunlaced nonwoven base cloth. The method comprises the following steps: longitudinally arranging the spunlaced nonwoven base cloth in parallel with a card clothing of a needle plate heat setting machine, carrying out heat pre-setting, taking out the obtained base cloth, and naturally cooling the base cloth to room temperature; rolling the preset spunlaced nonwoven base cloth on a plate vulcanizing machine, taking out the obtained base cloth, and naturally cooling the base cloth; uniformly mixing a coating with a thermal insulation coating and a diatomite-supported bio-enzyme coating to obtain a coating layer coating, carrying out primary knife coating on the pretreated punlaced nonwoven base cloth by a direct dry coating process, drying the coated base cloth, carrying out secondary knife coating, drying the coated base cloth, baking the dried base cloth, and calenderingthe base cloth; and impregnating the calendered punlaced nonwoven base cloth in an activated carbon impregnation solution, taking out the base cloth after the base cloth is completely wetted, carrying out solution removal treatment by a laboratory mangle, and then drying the obtained cloth in an oven to obtain the wallpaper.

Description

technical field [0001] The invention belongs to the technical field of wallpaper, and in particular relates to a method for preparing heat-insulating and formaldehyde-absorbable wallpaper with a spunlace nonwoven base cloth. Background technique [0002] Nonwoven wallpaper is favored by consumers because of its good air permeability, high strength, good dimensional stability, and low stretch rate. At present, the preparation methods of nonwoven wallpaper base fabric mainly include spunbond method and needle punching method. The research on the preparation of nonwoven wallpaper base fabric by spunlace method is still in its infancy. Therefore, research and exploration of spunlace nonwoven fabric application The feasibility in the field of wallpaper is of great significance for further expanding the application field of spunlace nonwovens. The present invention systematically studies the preparation and coating finishing of spunlace nonwovens used for wallpaper, and focuses o...
