Problems solved by technology

[0007] Existing flame retardants used to prepare flame-retardant wallpaper will produce a large amount of smoke and poisonous gas when burned, and the smoke released during the fire not only reduces visibility, increases people's psychological fear, hinders timely escape, but also It is not beneficial for firefighters to fight, and at the same time, it will cause non-thermal hazards (such as CO poisoning, etc.) due to the toxicity of gaseous products, which will cause huge obstacles to the rescue work at the fire scene

Embodiment 1

[0079] Embodiment 1 prepares OMMT

[0080] 1. Commercially available sodium-based MMT (molecular formula: Mx(Al 4 -xMg x ) Si 8 o 20 (OH) 4 , ion exchange capacity 80-120mmol / 100g) pulverized and sieved to obtain a powder with a particle size of 80-100 mesh; then add water to the MMT powder to swell the MMT powder to obtain a MMT-water-swellable product, wherein the volume of water is the same as that of MMT The weight ratio of the powder is 3:1;

[0081] 2. Add intercalation agent KH-560 (CH 3 -CH(OCH 2 -O(CH 2 ) 3 Si(OCH 3 ) 3 ), and after stirring evenly, carry out the modification reaction at a temperature of 80-85°C for 4-5h, wherein the weight ratio of MMT in the MMT-water-swellable product to KH-560 is 1.5:100;

[0082] 3. Centrifuge the reaction mixture, remove the supernatant, add distilled water to the centrifuged sediment for washing, centrifuge to remove excess alkylammonium and bromide ions, and use 0.1mol / L AgNO 3 The solution was tested for its absen...

Abstract

The invention discloses flame-retardant wallpaper as an indoor wall decoration material and a preparation method thereof. The preparation method for the flame-retardant wallpaper includes the following steps: after being immersed in a flame retardant solvent, a decorative veneer and a wallpaper substrate (backing paper) are ultrasonically immersed, so that a flame-retardant decorative veneer and a flame-retardant substrate are obtained; the flame-retardant decorative veneer is attached onto the surface of the flame-retardant substrate. The flame-retardant property of the wallpaper is good, the potential fire risk is low when the material burns, and the flame-retarding effect is remarkable; the smoke suppression effect is obvious, the amount of CO released from smoke is obviously reduced, toxic CO gas can be partially turned into non-toxic gas, and the wallpaper has a good effect of suppressing CO released at fire scenes. Moreover, since the adopted materials are natural materials, the wallpaper is safe to use.

Description

technical field [0001] The invention relates to a wallpaper and a preparation method thereof, in particular to a flame-retardant wallpaper and a preparation method thereof, and the invention belongs to the technical field of chemical engineering. Background technique [0002] Wallpaper, also known as wallpaper, English is wallpaper or Wallpaper, it is a widely used interior decoration material. Because wallpaper has the characteristics of various colors, rich patterns, luxurious style, safety and environmental protection, convenient construction, and reasonable price, which are incomparable to many other interior decoration materials, it has been widely popularized in developed countries and regions such as Europe, America, and Japan. Because wallpaper has certain strength, toughness, attractive appearance and good water resistance, it is widely used in the interior decoration of houses, offices, hotels, hotels, etc. [0003] Wallpapers are generally divided into the follow...
