Problems solved by technology

At the same time, the current flame retardant for wallpaper needs to be added in a large amount to have a certain flame retardancy, but when the flame retardant is added in a large amount, it will have a certain impact on the overall quality of the wallpaper. Hardness, brittleness, flexibility, and greatly reduced tear strength, etc., and once there is too much flame retardant in the wallpaper, the amount of black smoke and toxic gases generated during combustion will also increase sharply

preparation example 1

[0029] Diatomaceous earth, carbon black, bamboo fiber, titanate, aluminate and silane coupling agent were stirred at 3000rpm for 4h and heated at 150°C for 2.5h according to the weight ratio of 100:10:1:3:3:50. , drying, cooling and grinding to obtain the modified diatomite;

[0030] Modified diatomite, graphene oxide, antimony trioxide, chitosan, brass powder, basalt fiber (1 μm), asbestos fiber (2 μm) and ceramic fiber (2 μm) according to 100:5:3:10: Mix at a weight ratio of 1:5:10:10. Under a nitrogen atmosphere, heat up from 20°C to 400°C at a rate of 5°C / min, and keep at 400°C for 1.5 hours; then, at a rate of 5°C / min The cooling rate is lowered to 70°C and cooled naturally; the flame-retardant filler for wallpaper is obtained, which is recorded as W1.

preparation example 2

[0032] Diatomaceous earth, carbon black, bamboo fiber, titanate, aluminate and silane coupling agent were stirred at 3500rpm for 5h at a weight ratio of 100:12:3:4:5:60, and heated at 165°C for 2h. drying, cooling and grinding to obtain the modified diatomite;

[0033] Modified diatomite, graphene oxide, antimony trioxide, chitosan, brass powder, basalt fiber (2 μm), asbestos fiber (2 μm) and ceramic fiber (1 μm) according to 100:6:5:12: Mix at a weight ratio of 3:10:12:13. Under a nitrogen atmosphere, heat up from 30°C to 450°C at a rate of 8°C / min, and keep at 450°C for 1 hour; then, cool down at a rate of 10°C / min Cool down to 60°C and then cool naturally; the flame-retardant filler for wallpaper is obtained, denoted as W2.

preparation example 3

[0035] Diatomaceous earth, carbon black, bamboo fiber, titanate, aluminate and silane coupling agent were stirred at 4000rpm for 4h and heated at 180°C for 0.5h according to the weight ratio of 100:15:5:5:7:80. drying, cooling and grinding to obtain the modified diatomite;

[0036] Modified diatomite, graphene oxide, antimony trioxide, chitosan, brass powder, basalt fiber (2 μm), asbestos fiber (1 μm) and ceramic fiber (1 μm) according to 100:8:8:15: Mix at a weight ratio of 5:15:15:15. Under a nitrogen atmosphere, heat up from 40°C to 500°C at a rate of 10°C / min, and keep at 500°C for 1 hour; then, cool down at a rate of 10°C / min. Cool down to 70°C and then cool naturally; the flame-retardant filler for wallpaper is obtained, denoted as W3.

Abstract

The invention discloses a preparation method of a flame-retardant wallpaper base material. The preparation method comprises the following steps: mashing, mixing and cooking wood dust, bamboo leaves, tree bark, rice straw, folium artemisiae argyi, mint, convallaria, a flame-retardant filler and lime water according to a weight ratio of 100 to 15-55 to 20-30 to 10-15 to 3-10 to 2-6 to 5-10 to 10-20to 150-300 to obtain a pulp; washing the pulp, bleaching, beating, getting out paper, squeezing and baking the paper to obtain the wallpaper base material, wherein the reinforcing filler is prepared by mixing diatomite, graphene oxide, antimony trioxide, chitosan, a brass powder, basalt fiber, asbestos fiber and ceramic fiber and performing heat treatment. The flame-retardant wallpaper base material can greatly increase a preparation raw material of the prepared environment-friendly flame-retardant wallpaper, can greatly improve the flame retardance and the high temperature resistance of the prepared wallpaper, and is healthy and environment-friendly.

Description

technical field [0001] The invention relates to the field of wallpaper product manufacturing, in particular to a flame-retardant wallpaper base material and a preparation method thereof. Background technique [0002] Decorative materials are the material basis of architectural decoration engineering, and they are the actual effect of decoration engineering and the concrete display of the color, texture and texture of decorative materials. As an important part of modern home decoration, interior wall decoration materials are used in the overall home decoration. The largest proportion. At present, wall decoration materials on the market include paint, wallpaper, ceramics, glass, mirror surface, diatom mud, etc., which are rich in types and have different advantages. They can be flexibly selected according to the function and environment of each room. Among them, wallpaper is the most widely used among many materials. , The veneer material with the most varieties is widely use...
