Abstract

The invention discloses a modified fiber for wallpaper, and a production method thereof. The production method comprises the following steps: 1, mixing sodium silicate with a dispersant in the presence of a solvent, and carrying out water bath heating at 35-45 DEG C to prepare a mixture M1; 2, dropwise adding an aqueous solution of ammonium chloride to the mixture M1 prepared in step 1 under a 35-45 DEG C water bath heating condition, abandoning the obtained supernatant, and taking the obtained precipitate; 3, drying the precipitate, and calcining the dried precipitate to prepare granules; and4, adding the granules prepared in step 3 and a coupling agent to a water slurry containing fibers, and stirring and mixing all above materials at 60-80 DEG C for 1-3 h to produce the modified fiberfor wallpaper. The modified fiber produced through the above materials and the method can effectively improve the tension load of wallpaper made of waste paper pulp.

Description

technical field [0001] The invention relates to the field of fiber materials for wallpaper, in particular to modified fibers for wallpaper and a preparation method thereof. Background technique [0002] Wallpaper is widely used for its rich pattern and good performance, as well as the safety of materials, so its usage is also increasing. And adopt waste paper pulp to make wallpaper, although reached environmental protection performance, often the wallpaper tensile load of making is lower, makes it can not reach better usability. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a modified fiber for wallpaper and a preparation method thereof that still have a good tensile load under the premise of utilizing waste paper pulp. Contents of the invention [0004] In view of the above-mentioned prior art, the purpose of the present invention is to overcome the problem of using waste paper pulp to make wallpaper in the prior art. Althou...
