Description
Technical field
The present invention relates to wallpaper product manufacturing fields, and in particular, to a kind of environmental protection flame retardant wallpaper and preparation method thereof.
Background technology
Ornament materials is the material base of building decoration engineering, is the actual effect of decorative engineering and the color of ornament materials
Color, texture and the specific of texture show, and decorative material for internal wall is as component part important in modern house decorations,
It accounts for the largest percentage in whole house ornamentation.Wall decorative material currently on the market include coating, wallpaper, ceramics, glass, minute surface,
Diatom ooze etc., type is abundant, and advantage is different, can flexibly be selected according to each room function and environment, numerous materials wherein more than wallpaper
With the surface lining that most wide, kind are most in material, be widely used in restaurant in room interior wall and public place, market,
On the wall in hotel.
Wallpaper is increasingly becoming decorate home material since the 1980s, is the quite extensive indoor dress of current application
Exterior material.Initially originating from drawing on the paper Tang Dynasty, the wallpaper of Modern Significance, development are just evolved into through Britain's production printing again afterwards
Process successively experienced paper, scribble on paper, blistering paper, calico paper, to the process of version cruddy paper, special process paper.But it is existing
Wallpaper normally only there is single dicoration, mostly use artificial chemical materials greatly, lack other comprehensive performances, it is difficult to meet
People are for the higher requirement of wallpaper.
As wallpaper uses the raising of popularity rate, wallpaper is in public places and family's usage amount is increasing so that fire
Potential danger is significantly increased, and the flame retardant property of wallpaper also becomes hot issue of people's attention.Wallpaper belongs to inflammable product,
And the polyvinyl chloride that contains in wallpaper and specialty fibers will produce a large amount of smog in burning and two English classes are carcinogenic etc. has
Poisonous gas, this is the principal element for causing crowd's Poisoning choke in a fire.Current wallpaper fire retardant simultaneously, need additive amount compared with
Just have certain anti-flammability when big, but when fire retardant additive amount is more, there can be certain influence on the total quality of wallpaper, such as
Wallpaper can be caused poor appearance occur, hardened, frangible, the problems such as flexibility, tearing strength substantially reduce, once and in wallpaper
Fire retardant is excessive, and the yield for the black smoke and toxic gas that when burning generates can also increase severely.Therefore, how to ensure wallpaper resistance
Under the premise of firing performance, the dosage of wallpaper fire retardant how is reduced, does not influence wallpaper whole processing performance, and can effectively inhibit black
The generation of cigarette and toxic gas, this has become the hot spot studied at present.
