Gypsum plastering mortar capable of adsorbing formaldehyde
The invention relates to the technical field of building materials, and discloses gypsum plastering mortar capable of adsorbing formaldehyde. The gypsum plastering mortar is prepared from the following components in parts by weight: 800-990 parts of gypsum, 300-400 parts of coarse whiting, 80-100 parts of perlite, 1-3 parts of a thixotropic agent, 50-90 parts of an SC gypsum retarder, 123-211 parts of river sand fine particles, 300-352 parts of nano activated carbon, 155-236 parts of attapulgite, 255-300 parts of sepiolite particles and 155-366 parts of photocatalyst decomposition activated carbon. According to the plastering mortar, the nano activated carbon is newly added into the plastering mortar, fine gaps are formed in the nano activated carbon, the nano activated carbon can adsorb peculiar smells and even formaldehyde due to the characteristics of the nano activated carbon, the pore structure, pore distribution and the micropore surface area, and the nano activated carbon is resistant to acid and alkali and stable in performance; and attapulgite and sepiolite particles are newly added, the attapulgite and the sepiolite particles are both of a layer chain structure, the attapulgite and the sepiolite have good adsorption performance due to the specific structure, the sepiolite is soft when encountering water and becomes hard once dried, and the firmness of the plastering mortar can be improved.
本发明涉及建筑材料技术领域，且公开了一种吸附甲醛的石膏抹灰砂浆，按重量份包括以下组分：石膏800‑990份、重钙300‑400份、珍珠岩80‑100份、触变剂1‑3份、SC石膏缓凝剂50‑90份、河沙细粒123‑211份、纳米活性炭300‑352份、凹凸棒土155‑236份、海泡石颗粒255‑300份、光触媒分解活性炭155‑366份；通过在抹灰砂浆中新增纳米活性炭，纳米活性炭上具有细小的空隙，其本身所具有的特性与孔结构、孔分布、微孔表面积使得它能够吸附异味甚至甲醛，并且纳米活性炭耐酸碱，性能稳定，还新增了凹凸棒土，海泡石颗粒，由于凹凸棒土和海泡石颗粒海泡石均为层链状结构，它们所特有的结构,使得凹凸棒土和海泡石具有有很好的吸附性能，并且海泡石遇水柔软，一旦干燥就变硬，这样可以提高抹灰砂浆的坚固性。
