Abstract

The invention discloses a composition for powerfully decomposing formaldehyde and persistently degrading harmful substances and a preparation method of the composition. The composition is prepared from the following raw materials components in parts by weight: 0.6 to 0.8 part by weight of nanometer titania, 1.2 to 1.6 parts by weight of phytic acid, 0.1 to 0.3 part by weight of tea tree essentialoil, 1.5 to 2.0 parts by weight of Tween 20, 0.4 to 1.0 part by weight of polysorbate, 2.5 to 3.0 parts by weight of plant extract, 1.2 to 1.5 parts by weight of disodium EDTA, 0.2 to 0.4 part by weight of hydroxyethyl cellulose and 1.2 to 2.0 parts by weight of deacetylated chitin. The composition has no toxicity, harm, corrosion, oxidation or secondary pollution, and can be quickly degraded; bytaking the nanometer titania as a basic material, the composition really reaches 2 to 6 nano-levels, is clear, transparent, colorless or odor, and can eliminate and degrade unknown hazardous gases such as formaldehyde, benzene series, TVOC and ammonia under the condition of ultraviolet rays, visible light, lamp light or dark light.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a composition for powerfully decomposing formaldehyde and durably degrading harmful substances and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the public is increasingly concerned about their living environment and the impact of the environment on health. Problems such as excessive formaldehyde and VOC (volatile organic compounds) caused by the interior decoration process have gradually become the focus of public attention. Low-molecular-weight aldehyde is the main industrial raw material. Because low-molecular-weight aldehyde is active and soluble in water, it is easy to form a free state and disperse in the air, and adsorb on walls, indoor fabrics and decorative materials. Urea-formaldehyde resin glue is used in most wooden furniture, and there are harmful substances such as formaldehyde in a f...
