Abstract

The invention discloses an environment-friendly aqueous interior wall coating for removing formaldehyde. The environment-friendly aqueous interior wall coating comprises components in parts by weight: 20-30 parts of a pure acrylic emulsion, 10-20 parts of iron whiting, 5-10 parts of talcum powder, 8-15 parts of activated carbon, 2-8 parts of bamboo charcoal powder, 1-5 parts of diatomite, 3-9 parts of nano-titania, 2-8 parts of a dispersion agent, 3-7 parts of a defoaming agent, 2-6 parts of a thickening agent and 25-35 parts of deionized water. The environment-friendly aqueous interior wall coating for removing formaldehyde contains activated carbon and bamboo charcoal powder, has good adsorptive performance and is capable of absorbing formaldehyde released in the coating, so that the formaldehyde pollution can be effectively alleviated, and indoor air can be improved; the environment-friendly aqueous interior wall coating is applicable to the fields of decoration and renovation of interior walls of hospitals, schools, shops and residences.

Description

technical field [0001] The invention relates to the field of interior wall coatings, in particular to a formaldehyde-removing environment-friendly water-based interior wall coating. Background technique [0002] Formaldehyde is a recognized allergen, is also one of the potential strong mutagen, and is also one of the risk factors leading to childhood leukemia. According to domestic medical journals and related literature reports, the hazards of indoor formaldehyde to human health can be summarized as stimulating, toxic and carcinogenic. [0003] Formaldehyde mainly comes from plywood, blockboard, paint, coating and other decorative materials used for interior decoration, which brings certain harm to human health. [0004] At present, the water-based paint represented by latex paint widely used in the market has water as its dispersion medium, which has little environmental pollution. Therefore, wall coatings will still release harmful substances such as formaldehyde into t...
