Problems solved by technology

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

Embodiment Construction

[0019] Specific embodiments of the present invention will be further described below. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not constitute a conflict with each other.

[0020] This specific embodiment discloses a preparation method of a release paper-free film wall covering, and the finished wall covering is obtained by mixing, polymerizing, extruding, melt-blowing, air-flow traction, wire spinning and compounding;

[0021] Mixing: Add 80%-90% by weight of TPU raw materials, 1-2% by weight of chain extenders and 10-20% by weight of tackifiers into the mixing tank and mix thoroughly;

[0022] Polymerization: adding 10% by weight of isocyanate to carry out polymerization reaction, the r...

Abstract

The invention discloses a preparation method of release paper-free glue film wallpaper. The finished wallpaper is prepared through mixing, polymerization, extrusion, melt-blowing, airflow traction, wiring net formation and composting. The preparation method has the advantages that by mixing a tackifier with a TPU raw material, the viscosity of the TPU resin is improved; a glue film is formed through melt-blowing, airflow traction and wiring net formation and is composited with a composite layer through hot melting, so that the glue failure condition can be effectively avoided, and the strengthis enhanced; by utilizing a hot melt glue film, the weather resistance is strong, and the problem that the whole wallpaper is not wide enough is effectively solved; and the composite layer is torn down to be directly fit during the cloth adhesion, so that the wallpaper is convenient, practical and low in cost.

Description

technical field [0001] The invention relates to a resin film, in particular to a method for preparing a release paper-free film wall covering. 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 adhesives for posting will cause the glue...
