Gypsum-based decorative mortar and preparation method thereof
The invention provides gypsum-based decorative mortar and a preparation method thereof. The mortar is prepared from, by weight, 80-95 parts of building gypsum powder, 5-20 parts of aluminate cement and 2-5 parts of amino cellulose, the building gypsum powder can be prepared from one of desulfurized gypsum, ardealite, titanium gypsum and raw gypsum. The gypsum-based decorative mortar disclosed by the invention can be obtained by crushing and sieving the building gypsum powder and then mixing the building gypsum powder with amino cellulose. Amino cellulose with a certain reaction aldehyde removal effect is adopted as A retarder and A water-retaining agent, so that the mortar has a certain reaction aldehyde removal effect, other properties of the mortar are not affected, and the mortar has a good application prospect.
本发明提出了一种石膏基装饰砂浆及其制备方法，所述砂浆按重量份数计算，包括建筑石膏粉80‑95份、铝酸盐水泥5‑20份和氨基纤维素2‑5份，其中所述建筑石膏粉可以采用脱硫石膏、磷石膏、钛石膏和原石膏中的一种生产制得，通过将建筑石膏粉粉碎过筛后与氨基纤维素混合即可得到本发明的石膏基装饰砂浆。本发明采用具有一定反应除醛效果的氨基纤维素作为缓凝剂和保水剂，可以使砂浆自身具有一定反应除醛作用，同时不会影响砂浆的其他性能，具有良好的应用前景。
