Method for fabricating non-woven paper ripple foaming wallpaper

Abstract

The invention discloses a method for fabricating non-woven paper ripple foaming wallpaper. According to the method, relatively environment-friendly non-woven paper is selected as a base material for non-woven paper ripple foaming; a printing material is a ripple foaming material of changing the melting point; and the melting point is 180 degrees and is consistent with that of polyvinyl chloride (PVC). In order to ensure the ripple foaming height, a PVC paint is printed by two laser gravures to ensure that the height of the PVC printing layer reaches the requirements; finally a laser gravure ripple foaming material is printed on the PVC printed layer again; by the characteristic that the melting point of the PVC is the same as that of the ripple material, an organic matter and a plasticizer in the PVC fully volatilize; and the PVC and the ripple material are foamed together to ensure the foaming height and the foaming effect of the ripple material. Compared with traditional PVC ripple foaming, the non-woven paper ripple foaming procedures are reduced; a coating process flow is not needed; printing and foaming are directly carried out on a gravure press; and the wallpaper does not contain the organic matter or the plasticizer, so that the method is relatively environment-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, and the foaming temperature of the wrinkled material is 160-170 degrees), when the oven temperature reaches 160-170 degrees, 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 such products content and...
