Description

Production method of high-flame-retardancy wall cloth

Technical Field

The invention relates to the technical field of preparation of flame-retardant wall cloth, in particular to a production method of high-flame-retardancy wall cloth.

Background

The trend that wall cloth is used for replacing paint and coating in most of the current indoor wall decoration is that the worldwide sales volume of the wall cloth decoration material all the year is about several billion square meters. The wall cloth has various varieties and inexhaustibility, from the popular paper coating to the advanced wool weaving jacquard, from the single color to the multi-color, and from chemical fiber weaving, straw weaving, silk weaving, micro-veneer, flocking, foaming plastic and the like.

Along with the improvement of the fire safety consciousness of people, the fireproof performance of various decorative articles used daily is correspondingly improved. In particular, the recent national level has made higher demands on the fire protection performance in the public domain. Wall cloth is used more and more widely as common interior decoration fabric. The conventional flame-retardant wall cloth is generally subjected to flame-retardant treatment in an after-finishing mode. Can not achieve the purpose of permanent flame retardance, and the cloth surface after flame retardant treatment has flame retardant residues which are not beneficial to human health. Meanwhile, the production process has the environmental protection problems of waste gas and waste water pollution and the like, and the ecological environment can be seriously damaged.

In order to solve the above problems, workers in the field have made various studies on the production method of high-flame-retardant wall cloth:

chinese patent application number 200820084649.6 discloses a glass fiber curtain cloth, which comprises a weaving strip for weaving the curtain cloth, and is characterized in that: at least part of the braided strip comprises an inner core part and an outer layer part coated outside, wherein the inner core part is made of glass fiber, and the outer layer part is made of PVC material. The utility model has the advantages of simple manufacturing process, easy operation and high quality qualification rate of the produced products; the product is that the PVC material wraps up the glass fiber core in the mould through the state of melting, makes the strip of weaving have intensity height, and can directly absorb the ultraviolet ray in the light, still has good light transmissivity.

However, in the application patent, the glass fiber is wrapped by the PVC material, the outer layer is made of the PVC material, the PVC material is nonflammable, but can be burnt to reach a molten state when reaching a certain melting point, and in the burning process of the PVC, the PVC firstly has dehydrochlorination reaction, then has a series of reactions such as crosslinking, cyclization and chain scission, and is continuously burnt to generate carbon monoxide, carbon dioxide, benzene-containing cyclic compounds and carbon smoke dust, so that the environment and the personal safety are greatly harmed.

Therefore, there is a need for further improvement of the production method of the high flame-retardant wall covering to solve the above-mentioned disadvantages.
