Wallpaper base membrane and preparation method thereof

The invention discloses a wallpaper base membrane comprising the following components in parts by weight: 1-3 parts of a TiO /diatomite composite photocatalysis material, 20-40 parts of a polymer emulsion, 0-5 parts of an antiseptic agents, 0-5 parts of an antimicrobial agent, 0-0.5 part of an antifoaming agent, 0-0.5 part of a dispersing agent, and 20-80 parts of water. According to the wallpaper base membrane provided by the invention, the TiO /diatomite composite photocatalysis material capable of catalyzing decomposition of formaldehyde is added to the base membrane, in addition, contact area between walls and indoor environment is large, so that the contact area between the base membrane and the indoor environment is large as well, thus volatile pollutant, which is formaldehyde, generated by indoor decoration can be decomposed continuously and effectively. 本发明提出种墙纸基膜，其中所述墙纸基膜包括以下重量份的组分：TiO/硅藻土复合光催化材料1～3份；高分子乳液20～40份；防腐剂0～5份；抗菌剂0～5份；消泡剂0～0.5份；分散剂0～0.5份；水20～80份。本发明提出的墙体基膜，于基膜中添加具有催化分解甲醛作用的TiO/硅藻土复合光催化材料，能够
