Abstract
The invention discloses a wall material capable of removing formaldehyde, which comprises a wall plastering mortar layer and a functional layer coated on the surface of the wall plastering mortar layer; the wall plastering mortar layer comprises 80-100 parts by weight of ordinary portland cement, 100-150 parts by weight of sand, 5-10 parts by weight of porous EVA material, 1-2 parts by weight of retarder, 2-3 parts by weight of cellulose ether, 1-2 parts by weight of water reducer and 70-80 parts by weight of water; the functional layer comprises, by weight, 30-50 parts of acrylic emulsion, 15-20 parts of nano titanium oxide/biological ceramic/diatomite composite filler, 0.5-1 part of drier, 1-2 parts of film-forming assistant, 1-2 parts of defoaming agent and 15-20 parts of water. The invention also provides a preparation method of the wall material. The wall material provided by the invention has good binding performance with a matrix, can effectively remove formaldehyde, has good mechanical property, has certain heat-insulating property, and is simple in preparation method.
Description
Technical Field
The invention relates to the field of building materials, in particular to a wall material capable of removing formaldehyde and a preparation method thereof.
Background
With the improvement of the living standard of people, the environmental awareness and the consumption idea of people are also raised to different dimensions. The quality of the living environment and the environmental requirements are also increasing. Formaldehyde is one of the main pollutants in indoor air, and the excessive concentration of formaldehyde causes teratogenesis, carcinogenesis and mutagenicity to human beings and organisms. In China, formaldehyde is the second place on the name list of toxic chemicals.
