Problems solved by technology

The release paper process cannot be used to produce flower-absorbing products without base fabrics, because the production of semi-finished products without base fabrics needs to be produced with flat paper first, and after peeling off, the flower-absorbing process is processed in the later stage, because there is no basis for the processing of products without base fabrics. Fabric support, under the high temperature melting when absorbing flowers, the leather material becomes soft and easy to break, the tension cannot be controlled and the width is insufficient, the temperature of the leather material is too low when absorbing flowers, the processing lines are not clear, the efficiency is low when absorbing flowers, and it cannot be operated

preparation example Construction

[0015] The invention provides a method for preparing artificial leather without base cloth, which comprises the following steps:

[0016] (1) Coating the configured surface layer slurry on the release paper and drying;

[0017] (2) Apply the configured foam layer slurry on the dried surface layer slurry, and foam to a specified ratio;

[0018] (3) Coat the configured back coating slurry on the foamed foam layer slurry, and then dry until the back coating slurry is in a molten state, at this time, perform flower absorption treatment, cooling and setting Finally, the release paper is peeled off to obtain the flower-absorbing artificial leather without base cloth.

[0019] The present invention also provides a base-cloth-free flower-absorbing artificial leather, which is prepared by the above-mentioned preparation method of the base-free flower-absorbing artificial leather.

[0020] As can be seen from the foregoing description, the beneficial effects of the present invention a...

Embodiment 1

[0034] The flower-absorbing artificial leather without base cloth of the present embodiment is polyvinyl chloride (PVC) flower-absorbing artificial leather without base cloth, and its preparation method comprises the following steps:

Abstract

The invention relates to a non-base cloth flower-absorbing artificial leather and a preparation method thereof. The preparation method of the non-base cloth flower-sucking artificial leather includesthe following steps: (1) coating a prepared surface layer slurry material on a release papers and drying; (2) coating the prepared foaming layer slurry material on the dried surface layer slurry material and foaming to a specified magnification; (3) coating the prepared back coating slurry material on the foaming layer slurry material after foaming, and then drying until the back coating slurry material is in a molten state, performing flower absorption treatment at this time, stripping the release papers after cooling and shaping, and obtaining the base cloth-free flower absorption artificialleather. The preparation method of the non-base cloth flower-absorbing artificial leather has the advantages of improving the processing temperature of the leather and effectively controlling the adverse phenomena of the leather such as deformation, fracture, paste and the like.

Description

technical field [0001] The invention relates to artificial leather technology, in particular to a fabric-absorbing artificial leather without base fabric and a preparation method thereof. Background technique [0002] In the existing coating process, the lines of artificial leather non-base fabric products are formed by different pattern carriers of release paper. If it is necessary to imitate the calendering process to absorb the pattern, it is necessary to use the calendering non-base fabric production process to produce. This kind of process requires high cost, many processes, and requires a special base cloth as a carrier to set off the leather surface. After processing, the base cloth must be peeled off separately, resulting in a large loss in yield. Now a set of flower-absorbing machine equipment is added to the artificial leather coating machine equipment, and the release paper product without base fabric absorbing flowers can be realized quickly through formula adjus...
