Abstract

The invention discloses water-resistant interior and exterior wall putty capable of absorbing and burying carbon dioxide in air. When the putty is prepared by the following materials in parts by weight when serving as interior wall putty: 24-60 parts of calcium hydroxide, 20-30 parts of heavy calcium carbonate, 20-30 parts of diatomite, 0.1-1 part of hydroxyethyl methyl cellulose and 0.05-0.5 part of catalyst; and when the putty is served as the exterior wall putty, 20-40 parts of white cement and 1-5 parts of re-dispersible glue powder are further added. The putty of the invention has the advantages of absorption and burial of carbon dioxide in air, sterilization, disinfection and air purification and strong water-resistance after being dried and solidified.

Description

technical field [0001] The invention belongs to the technical field of building materials. Specifically relates to a water-resistant interior and exterior wall putty that can absorb and bury carbon dioxide in the air. Background technique [0002] The international community now attributes global temperature warming, glacier melting, and sea level rise to CO2 due to the greenhouse effect. 2 The rapid increase of the population has destroyed the environment of the earth on which people live. To curb excess emissions of CO 2 , the international community signed the "Kyoto Protocol" and "Copenhagen Letter of Intent", which shows that CO 2 How important is the reduction of the earth's environment on which we live. At present, most of the putties on the market cannot absorb and bury carbon dioxide in the air, and generally have poor quality and environmental protection. Most of them are processed with organic substances such as 801 glue. This kind of putty itself has no curi...
