A kind of production technology of flame-retardant wall blanket

Abstract

The invention relates to a novel flame-retardant wall carpet. A production process of the novel flame-retardant wall carpet is characterized in that chemical fiber short filaments are used as the raw material, opening, mixing, carding and web laying are performed to form an even fiber web, needling is performed to reinforce the fiber web to obtain a wall carpet body, the upper surface of the wall carpet body is evenly coated with expanded graphite flame-retardant adhesive, the upper surface coated with the expanded graphite flame-retardant adhesive is placed upwardly, and flame is applied to the lower surface of the wall carpet body to perform singeing and drying to obtain the flame-retardant wall carpet. The production process specifically includes the steps of firstly, preparing the raw material; secondly, mixing regenerated short fibers to form the web; thirdly, reinforcing the fiber web; fourthly, coating the expanded graphite flame-retardant adhesive; fifthly, performing singeing and drying, to be more specific, placing the wall carpet body coated with the adhesive into drying equipment, and using the flame to evenly burn the wall carpet body to allow the lower surface of the wall carpet body to be even and flat and dry the flame-retardant adhesive on the upper surface of the wall carpet body; sixthly, rolling. The production process has the advantages that high production efficiency is achieved, and the produced wall carpet is excellent in flame retardance while product forming performance and surface quality are guaranteed effectively.

Description

technical field [0001] The invention relates to the technical field of flame-retardant fabrics, in particular to a production process of flame-retardant wall blankets. Background technique [0002] Flame-retardant wall blanket is also called needle-punched non-woven wall blanket. It is made of synthetic flame-retardant fibers through needle-punching process, and then made of blanket-covered pavement roll with a certain hardness by invading glue. The general width is 1.5 meters and the length is 30-50 meters. The flame-retardant wall blanket is made of short fibers laid out into a net shape through different equipment and processes. After acupuncture and other processes, different fibers are interwoven with each other, intertwined and fixed to make the fabric standardized, making the fabric soft, plump, thick, Stiff to achieve different thicknesses to meet the requirements of use. The needle-punched gray cloth is glued on the back, dried and shaped, trimmed, and packaged i...

Problems solved by technology

[0006] Although the method of applying flame retardant glue with a scraper has changed the traditional method of soaking flame retardants for flame retardant finishing, it can also have better flame retardant performance, but the method of scraping the flame retardant glue with a scraper needs to use The scraper fully contacts the fabric. In order to make the flame retardant glue fully penetrate into the substrate and ensure the uniform coating of the flame retardant glue, it is necessary to exert a certain pressure on the scraper. In this way, the scraper will It will scratch the surface of the substrate and affect the final quality of the fabric

Since the flame-retardant wall carpet needs to be coated with adhesive on the lower surface when it is fixed to the wall, the length of the short fibers on the surface of the wall carpet body obtained after acupuncture reinforcement is different, and the surface is uneven. It is easy to appear that the paste is not firm and falls off. At present, this problem cannot be solved.
