Abstract

The invention discloses a modified bamboo pulp fiber wallpaper preparation method, and belongs to the wallpaper technical field; the method comprises the following steps: using bamboo pulp fiber as raw material; using high sodium iodate solution to soak and oxidize the bamboo pulp fiber so as to obtain oxidation bamboo pulp fiber; combing the bamboo pulp fiber with sericin for graft modification under high temperature; drying the material, and carrying out ultrasonic vibration reaction with chitosan degraded liquid; filtering the material so as to obtain filter residue; using cuprammonium solution to soak and wash the filter residue so as to obtain the modified bamboo pulp fiber; using paper pulp mold equipment to process the modified bamboo pulp fiber through cold press and hot pressing procedures, thus obtaining the modified bamboo pulp fiber wallpaper. Embodiment shows, the bamboo pulp fiber wallpaper is more obvious in antibiosis capability, and bacteriostasis rate can reach above 65%; the novel wallpaper is sound-absorbing, good in heat insulation, waterproof moistureproof, and can prolong the life for 2-3 years when compared with a normal wallpaper.

Description

technical field [0001] The invention discloses a preparation method of modified bamboo pulp fiber wallpaper, which belongs to the technical field of wallpaper. Background technique [0002] With the continuous development of the social economy and the improvement of people's living standards, a large number of hotels and residences have sprung up, and people's requirements for interior decoration have increased, and they have paid more attention to the decorative effect of the wall surface. Wallpaper is an important part of modern interior decoration materials, and it is one of the main decoration materials for interior wall surfaces. Because wallpaper has a good decorative effect, wallpaper has been used more and more, so more and more people are committed to it. Research on wallpaper, but most of the research stays on the decorative effect of wallpaper, such as changing the color of the wallpaper, and pays more attention to the surface. [0003] At present, the most widel...
