It is characterized by the use of chemical oxidation reaction to degrade formaldehyde, the cost is relatively high, and substances harmful to the body such as ozone may be produced, there are discontinuous degradation, unstable degradation effect, inconvenient use, and high volatility
The bioabsorption method is to use specific plants to absorb formaldehyde and achieve the purpose of formaldehyde absorption and transformation through photosynthesis. It is characterized by low absorption rate and long absorption and transformation cycle.
The adsorption method mainly uses solid adsorbents. At present, solid adsorbents based on various activated carbons and their products, through the adsorption principle, have poor formaldehyde purification effects and are far from meeting the requirements for purifying formaldehyde.
[0004] At present, there are several types of formaldehyde purification materials: first, porous zeolite and activated carbon-based purification materials based on physical adsorption method, formaldehyde purification is mainly adsorption, and the purification capacity is limited; second, environmental mineral materials such as Nano photocatalytic materials with sepiolite and zeolite as the carrier, use photocatalystase to catalyze the oxidation reaction to degrade formaldehyde, the cost is relatively high, the degradation is discontinuous, the degradation effect is unstable, and it is inconvenient to use; Or the inorganic macromolecular polymer forms a porous porous adsorption to formaldehyde, and then performs nucleophilic addition reaction or chemical bonding degradation to formaldehyde by the internal small molecule functional group components, the adsorption rate is low, and the absorption conversion cycle is long

Abstract
The invention provides a composite material with formaldehyde purification function, which is prepared by dissolving 45-73 parts by weight of powder with formaldehyde purification function, and one or both of 0.15-1.2 parts by weight of reinforcing fiber and 15-20 parts by weight of filling material in 20-40 parts of compound solution. The powder with formaldehyde purification function is prepared by mixing 38-55 parts by weight of calcic inorganic base, 6-16 parts by weight of algae and 3-6 parts by weight of modifier; and the compound solution is compounded from 100 parts by weight of clear water, 1.5-2.0 parts by weight of crystal modifier, 0.4-0.5 part by weight of waterproofing agent and 0.4-0.5 part by weight of defoaming agent. The formaldehyde adsorption rate of the composite material is 95%, the formaldehyde purifying effect durability is up to 90%, the methylbenzene adsorption rate is 68.5%, and the methylbenzene purifying effect durability is up to 50.4%. Compared with the chemical process, biosorption process and adsorption process adopted by the traditional formaldehyde purification material, the invention has the advantages of natural and environment-friendly raw materials, obvious purifying effect, wide product derivation performance and low cost.
Description
technical field [0001] The invention belongs to the fields of building materials, light industry, chemical industry and the like, in particular to the field of building materials, and is used for improving indoor air quality. Background technique [0002] The sources of formaldehyde mainly include: (1) Urea-formaldehyde resin plywood, blockboard, medium densityfiberboard and particleboard, etc. Wood-based panels and furniture made of wood-based panels; (2) Other decorative materials containing formaldehyde, such as white latex, foam plastics, paints and coatings; Textiles prepared by adding formaldehyde additives, including bedding, wall coverings, wallpaper, chemical fiber carpets, curtains and fabric furniture. (4) Treatment of formaldehyde tail gas and waste liquid in the chemical industry; from the investigation of indoor formaldehyde pollution and the analysis of various building materials, it can be seen that building materials are an important source of indoor forma...
