Abstract

Negative ion gypsum-based putty powder and a preparing method are disclosed and belong to the field of building wall decoration materials. The putty powder comprises 600-750 parts by weight of powder of plaster of Paris, 250-400 parts by weight of an inert filler, 20-50 parts by weight of negative ion powder, 3-10 parts by weight of glue powder, 1-3 parts by weight of a water retaining agent and 0.3-1 part by weight of a retarder. The putty powder has characteristics of high adhesion strength, low shrinkage deformation, capability of preventing peeling, powder dropping and cracking, good workability, excellent construction properties, environment protection, and the like, and is suitable for puttying treatment of various walls. Negative ions can be effectively released through the negative ion powder, thus meeting desire for enjoying nature flavor for people and fundamentally changing the present living environment. The putty powder and the method have good development significance.

Description

technical field [0001] The invention relates to a negative ion gypsum-based full-batch powder and a preparation method thereof, belonging to the technical field of building wall decoration materials. Background technique [0002] The World Health Organization confirms that the content of negative ions in fresh air is 1000-1500 / cm 3 , the suburbs, seaside, forests, waterfalls, and grasslands all reach 3000 negative ions / cm 3 above, while the average family indoor content is less than 600 / cm2 3 . Excessively low negative ion content can induce many diseases. Meteorological experts believe that a big city like Beijing has a continental climate, and there are fewer negative oxygen ions in the air than in marine climate areas. In addition, the air pollution is more serious, and the negative oxygen ions in the air are easily absorbed by smoke, dust, germs, car exhaust, etc. Pollutants are adsorbed and disappear, indoor ventilation is poor and polluted, and negative oxygen ions...
