Embodiment 1

[0027] According to the patent (application number: 87105201), a composite PVC wallpaper with flame-retardant PVC film as the surface layer and flame-retardant paper as the bottom layer. The weight ratio of the flame-retardant PVC surface layer components is: 100 parts of PVC resin, phthalic acid 52 parts of dioctyl ester (DOP), 2 parts of liquid Ba-Cd-Zn, 1 part of three-salt lead stearate, 1 part of lead stearate, 0.2 parts of stearic acid, CaCO 3 80 parts, 5 parts of antimony trioxide; flame-retardant paper is made by impregnating non-flame-retardant paper with an aqueous solution containing 30% ammonium polyphosphate (weight white content), and then drying. According to the test of GB5454-1997, the flame-retardant PVC wallpaper made by this method has an oxygen index of 27%; according to the test of GB5455-1997, the damage length is >200mm, the smoldering time is >5s, and the burning time is >5s. In addition, the bottom layer of the wallpaper after flame-retardant treatme...

Embodiment 2

[0029] Composite PVC wallpaper with flame-retardant PVC coating as the surface layer and flame-retardant paper as the bottom layer. The weight ratio of flame-retardant PVC surface layer components is: 100 parts of PVC resin, 25 parts of dibutyl phthalate (DBP) , 5 parts of zinc borate, 5 parts of aluminum hydroxide, 10 parts of triethyl phosphate, 0.01 part of G-618CZ type calcium zinc stabilizer (Xiamen Tongan Lianxiang Chemical Co., Ltd.), 40 parts of talcum powder, azodimethazine 1 part of amide, 10 parts of toluene; the flame-retardant paper is made of non-flame-retardant paper firstly impregnated with 5% (weight percentage) of dicyandiamide, 10% (weight percentage) of ammonium polyphosphate, and 5% (weight percentage) of zinc borate. The flame retardant liquid is then made by drying. The flame-retardant composite PVC wallpaper, according to the test of GB5454-1997, has an oxygen index of 32%; according to the test of GB5455-1997, the damage length is 120mm, the smoldering...

Embodiment 3

[0031]Composite PVC wallpaper with flame-retardant PVC film as the surface layer and flame-retardant paper as the bottom layer. The weight ratio of the flame-retardant PVC surface layer components is: 100 parts of PVC resin, 50 parts of diisobutyl phthalate, hydrogen 20 parts of magnesium, 30 parts of diphenyl 2-ethylhexyl phosphate, 30 parts of chlorinated paraffin, 1 part of G-618CZ type calcium zinc stabilizer, 150 parts of calcium carbonate, 3 parts of toluene; The paper is firstly made by impregnating a flame retardant solution containing 3% (weight percent) of melamine, 4% (weight percent) of ammonium polyphosphate and 3% (weight percent) of boric acid, and then dried. The flame-retardant composite PVC wallpaper, according to the test of GB5454-1997, has an oxygen index of 33%; according to the test of GB5455-1997, the damage length is 100mm, the smoldering time is 0, and the continuous burning time is 1s; according to the test of GB8624-2006, the combustion performance r...

Abstract

The invention relates to composite wallpaper containing polyvinyl chloride and discloses composite polyvinyl chloride (PVC) wallpaper with a flame retarding polyvinyl chloride (for short flame retarding PVC) coating or film as a surface layer and flame retarding paper as a bottom layer. Components of the flame retarding PVC surface layer, by weight ratio, comprise PVC resin 100, a plasticizer 0-50, a flame retardant 20-80, a stabilizing agent 0.01-1, filler 40-150, a foaming agent 0-1 and a thinning agent 0-10. Paper which is not flame retarding is soaked, flame retarding liquid is sprayed or brush-coated on the paper which is not flame retarding, and then drying is conducted to obtain the flame retarding paper. Compared with a traditional processing method of adopting antimonous oxide as a PVC surface layer flame retardant and adopting ammonium polyphosphate as a paper base layer flame retardant, the flame retarding PVC wallpaper is environment-friendly, low in toxicity and small in smoke density during burning, oxygen index can reach above 32%, and burning performance can reach a GB8624-2006B level.

Description

technical field [0001] The invention relates to wallpaper, in particular to a composite wallpaper containing polyvinyl chloride. Background technique [0002] As a kind of interior decoration material for rooms, wallpaper is not only widely used in public places such as restaurants and hotels, but also has entered thousands of households along with the improvement of people's living standards and housing conditions. Decorative wallpaper, although it can beautify the room, is a potential fire hazard because the commonly used wallpaper is flammable. Once a fire breaks out in the room, the wallpaper may be ignited, or the flame may spread along the wallpaper to expand the fire. From the perspective of fire safety, it is necessary to develop and use non-combustible or flame-retardant wallpapers. [0003] With the enhancement of people's awareness of fire protection and environmental protection and a series of national standards, such as GB50222-95 "Code for Fire Protection Des...
