Problems solved by technology

[0006] At present, the research on wall coverings mainly involves the bonding of wall coverings, reducing the content of formaldehyde in wall coverings or the amount of formaldehyde released, etc. However, there are few targeted studies on how to prevent wall coverings from deforming.
In fact, during the use of wall coverings, especially after long-term use, the wall coverings will be deformed, bulged, and warped after the alternating changes of cold and heat in spring, summer, autumn, and winter.
To solve the problem of wall covering warping, in reality, sticky adhesives are often used for bonding, or adhesives are added after warping occurs, and the increase in the content of adhesives will increase the probability of formaldehyde release , or cause the wall covering to change color, affecting the beauty of the decoration

preparation example Construction

[0015] The invention provides a method for preparing a seamless long-fiber non-woven fabric-based wall covering. The preparation method comprises the following steps: (1) coating the adhesive on the surface of the non-woven fabric, and then laying the long fiber on the surface of the non-woven fabric. The surface of the adhesive is then preliminarily dried to obtain a first product; (2) the first product is sequentially subjected to the first treatment and the second treatment to obtain a processed product; (3) the processed product is compacted treatment; wherein, the temperature of the first treatment is 50-80°C higher than the temperature of the second treatment.

[0016] Through the above-mentioned technical scheme, the present invention formulates the production process of the wall cloth, especially the first treatment and the second treatment are carried out sequentially on the initial product, the temperature of the first treatment is 50-80°C higher than the temperature ...

Abstract

The invention discloses a method for preparing seamless long fiber non-woven fabric based wall cloth. The preparation method comprises the following steps: (1) coating an adhesive onto the surface ofa non-woven fabric, laying long fibers onto the surface of the adhesive, and performing primary drying so as to obtain a primary product; (2) sequentially performing primary treatment and secondary treatment on the primary product so as to obtain a treated product; and (3) compacting the treated product, wherein the temperature of the first treatment is 50-80 DEG C higher than the temperature of the second treatment. The seamless long fiber non-woven fabric based wall cloth has excellent resistance to alternate cooling and heating changes, and particularly does not deform or warp after being subjected to alternate changes of four seasons, namely spring, summer, autumn and winter, in actual application, and the phenomena of bulging and warping of the wall cloth are greatly reduced. Meanwhile, the preparation method has the advantages of simple process and readily available raw materials.

Description

technical field [0001] The invention relates to wall coverings, in particular to a seamless long-fiber non-woven fabric-based wall covering and a preparation method thereof. Background technique [0002] Wall covering or wallpaper is a widely used interior decoration material.
