Abstract

The invention discloses waterproof putty paste capable of removing formaldehyde. The waterproof putty paste is prepared from, by mass, 0.3-0.7 parts of hydroxypropyl methyl cellulose, 12-16 parts of water, 18-32 parts of ash calcium powder, 12-35 parts of 325-mesh talcum powder, 15-22 parts of 325-mesh calcium carbonate, 10-18 parts of ground calcium carbonate, 2-4 parts of kieselguhr and 4-8 parts of nanometer TiO2 / kieselguhr photocatalytic composite material. The waterproof putty paste is low in consumption, lowers coating consumption, improves the coating effect, is suitable for cement mortar walls, and is the optimal preferred material for diatom ooze, emulsion paint and wall paper, and particularly the cost of putty for two or more times of decorating can be saved. Under the illumination conditions, nanometer TiO2 / kieselguhr photocatalytic composite material conducts adsorption, capture, photocatalysis and degradation, indoor gas-state pollutants such as formaldehyde and methylbenzene are removed, and the formaldehyde degradation rate within 72 hours reaches up to 80% or higher.

Description

technical field [0001] The invention relates to the field of architectural decoration, in particular to a formaldehyde-removing water-resistant putty paste. Background technique [0002] According to the "Building Indoor Putty" (JG / T298-2010) standard, all indoor building putty is divided into three categories: the worst category is "fake and inferior putty" that cannot meet this standard. This kind of putty is mainly mineral powder and glue It is mixed and made on site, which is easy to bulge, peel, crack, and has a very short lifespan. For example, "scraping white" in the northern region and "batch old powder" in Jiangsu and Zhejiang regions all belong to this category; General putty standard products, the use of which has been explicitly restricted in the Beijing area. Although the firmness has been slightly improved, it is still easy to peel and crack, and has a short service life. 821 putty is the typical one; the best It is water-resistant putty, which is not only str...
