According to the novel fire-retardant wallpaper, the auxiliaries are added, and air can be purified. The produced wallpaper is high in surface finish degree, good in smoothness, free of extraneous odors, environmentally friendly and waterproof, has the excellent fire resistance, and is fire-retardant, good in safety performance and suitable for large-scale production.

Description

A kind of novel difficult combustion wallpaper

Technical field

The present invention relates to wallpaper field, particularly a kind of novel difficult combustion wallpaper.

Background technology

Wallpaper, also referred to as wallpaper, English is Wall paper or Wallpaper, it is a kind of application house decorative material quite widely.The incomparable features of multiple other house decorative material such as color is various because wallpaper has, pattern is abundant, luxurious style, safety and environmental protection, easy construction, price are suitable, therefore in developed countries such as America and Europe, Southeast Asia, Japan with regionally obtain popularizing of certain degree.Wallpaper is divided into a lot of classes, as coating wallpaper, overlay film wallpaper, embossing wallpaper etc.Conventionally produce body paper with bleached wood pulp, then through the processing processing of different operations, cover and mould as coating, printing, embossing or surface, after cutting, packing, dispatch from the factory.Because there is certain intensity, appearance attractive in appearance and good water repelling property, be widely used in the interior decoration in house, office, hotel etc.Wallpaper is as a kind of important house decorative material, and its fireproof performance is extremely important.Since the fireproof performance new standard GB8624-2006 of wallpaper replaces after old standard GB8624-1997, the intension of wallpaper combustion characteristics, also from simple flame propagation with spread, has been expanded to comprehensive parameters such as comprising combustion heat rate of release, hot burst size, smoke density and product toxicity.Therefore, the wallpaper of producing from now on must redesign and optimize material type selecting and formula, makes it meet new fire protection requirement.

Summary of the invention

The object of this invention is to provide a kind of novel difficult combustion wallpaper.
