Preparation method of release-paper-free adhesive film wall cloth

Abstract

The invention relates to a preparation method of release-paper-free adhesive film wall cloth. The preparation method comprises the following steps: S1, preparing a hot melt adhesive film; s2, selecting a wall cloth base material: preparing figured cloth and spun-bonded non-woven fabric, taking the figured cloth as a wall cloth fabric, and taking the spun-bonded non-woven fabric as a wall cloth base; s3, positioning the wall cloth compounding device; s4, positioning a wall cloth base material; and S5, leveling treatment is carried out. The device has the following advantages that the production quality and the yield of the composite wall cloth are guaranteed, the composite defects of internal bulging, bar marks, wrinkles and the like of the composite wall cloth are avoided, tension adjustment of the wall cloth fabric, the wall cloth substrate and the hot melt adhesive film can be synchronously achieved, and the adjustment efficiency is improved.

Description

Technical field: [0001] The invention relates to the field of composite wall coverings, in particular to a method for preparing release paper-free adhesive film wall coverings. Background technique: [0002] Wall cloth, also known as "wall cloth", is the fabric for pasting the wall, using cotton cloth as the base cloth, and imposing printing or embossing on the base cloth, or jacquard weaving, and the patterns used are mostly geometric figures and flower patterns. . It is beautiful and elegant for modern decoration. The wall coverings in the prior art are usually pasted by brushing glutinous rice glue, release paper and pressure-sensitive adhesive. It is easy to cause mildew and has poor weather resistance. However, due to the limitation of the width of the release paper, seams will be generated when the release paper is used to transfer, which will affect the aesthetics, and the method of transferring is cumbersome and inconvenient. However, the use of subsensitive adhesi...

It is beautiful and elegant for modern decoration. The wall coverings in the prior art are usually pasted by brushing glutinous rice glue, release paper and pressure-sensitive adhesive. It is easy to cause mold and has poor weather resistance. However, due to the limitation of the width of the release paper, seams will be generated when the release paper is used, which will affect the aesthetics, and the way of transferring is troublesome and inconvenient.

However, the use of sub-sensitive adhesive for posting will cause the glue to open due to insufficient viscosity of the pressure-sensitive adhesive, and the cost of posting the pressure-sensitive adhesive is relatively high

[0003] Therefore, the wall covering fabric and the wall covering base are combined to form a composite wall covering through a hot-melt adhesive film, which has the advantages of non-toxicity, sound absorption, crispness, aging resistance, and moisture resistance. When laminating through hot-melt adhesive film, it is usually wound and conveyed by rollers such as feeding rollers, conveying rollers, and pressing rollers. Wrinkles appear, and the composite wall covering will have local internal bulges, stripes and wrinkles, which will affect the production quality and yield of the wall covering. If the wall covering fabric, wall covering base and hot-melt adhesive film The tension adjustment is performed by adjusting the height of the roller body separately, so the adjustment workload is large, time-consuming and labor-intensive
