Problems solved by technology

Common putty powders on the market are mainly composed of white cement, inert fillers, and chemical additives, which are obtained by uniform mixing. This dry powder material can be directly mixed with water as required to form a paste, which can be scraped and applied. However, cement is used as cement. Traditional putty inevitably has defects such as easy shrinkage, cracking, peeling and peeling of cement-based materials
In recent years, in some reported patents, building gypsum, desulfurized gypsum, and fluorine gypsum are used as base materials to prepare putty, but there are still shortcomings such as poor stability, strength and hardness that cannot meet specific construction requirements, etc.

Abstract

The invention discloses environment-friendly interior wall putty with an indoor humidity adjustment function, and relates to the technical field of building coatings. The environment-friendly interior wall putty comprises, by weight, 60-70 parts of gypsum powder, 20-25 parts of acrylic acid, 10-15 parts of tephra, 10-15 parts of plant starch, 8-12 parts of disproportionated rosin, 6-10 parts of ceramic micropowder, 6-10 parts of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, 5-8 parts of carbomer resin, 5-8 parts of polyacrylamide, 4-6 parts of fumed silica, 4-6 parts of sticky rice glue, 3-5 parts of microcrystalline wax, 3-5 parts of calamine powder, 2-3 parts of hydroxypropyl methyl celluloses, 2-3 parts of nano-powder, 2-3 parts of sodium hydroxide, 0.3-0.5 part of diethylenetriamine, 0.2-0.3 part of potassium peroxodisulfate and 50-70 parts of water. The environment-friendly interior wall putty has the advantages that the interior wall putty is highly environment-friendly, free of formaldehyde and poisonless, does not release harmful gas after being smeared onto interior walls and can adjust indoor humidity effectively.

Description

Technical field: [0001] The invention relates to the technical field of architectural coatings, in particular to an environmentally friendly interior wall putty capable of adjusting indoor humidity. Background technique: [0002] The inner wall putty is located between the wall leveling mortar and the coating layer, and plays an auxiliary role in further leveling and forming decorative texture patterns. The common putty powder on the market is mostly white cement, inert fillers, and chemical additives as the main components. They are obtained by uniform mixing. This dry powder material can be directly added with water and stirred into a paste to be applied by scraping. However, cement is used as a binder. Traditional putty inevitably has defects such as easy shrinkage, cracking, shelling and peeling of cement-based materials. In recent years, in some patents that have been reported, building gypsum, desulfurized gypsum, and fluorogypsum are used as base materials to prepare putt...
