A method of making non-woven paper crepe foam wallpaper

Abstract

The invention discloses a method for making non-woven paper wrinkled and foamed wallpaper. In the invention, the base material of the non-woven paper wrinkled and foamed is more environmentally friendly non-woven paper, and the printing material is a wrinkled and foamed material with a changed melting point. , the melting point is 180 degrees, consistent with the melting point of PVC. In order to ensure the height of wrinkle foaming, two laser gravure printing PVC coatings are used to ensure that the height of the PVC printing layer meets the requirements, and finally another version of laser gravure wrinkling foaming material is printed on the PVC printing layer, using PVC melting point It has the same characteristics as the melting point of the crepe material, fully volatilizes the organic matter and plasticizer in the PVC, and foams the PVC and the crepe material together to ensure the foaming height and the foaming effect of the crepe material. Compared with the traditional PVC wrinkle foam, the non-woven paper wrinkle foam not only reduces the process, does not require a coating process, and can be printed and foamed directly on the gravure printing machine, and the wallpaper does not contain organic matter and plasticizers, which will be more environmentally friendly .

Description

technical field [0001] The invention relates to a method for making wallpaper, in particular to a method for making non-woven paper wrinkled and foamed wallpaper. Background technique [0002] The base material of traditional PVC wrinkle foaming is PVC (base paper coated PVC). On the PVC coating, the wrinkle material is printed on the PVC coating with a rotary screen, and the irregular foaming and The melting point of the wrinkled material is lower than that of the PVC coating layer (the melting point of PVC is above 180 degrees Celsius, and the foaming temperature of the wrinkled material is 160-170 degrees Celsius). When the oven temperature reaches 160-170 degrees Celsius, the wrinkled foam The material foams and the PVC does not reach the melting temperature, thus forming a special foaming effect; because the PVC does not reach the melting temperature, the organic matter and plasticizer in the PVC cannot be effectively volatilized, and eventually the organic matter in su...
