Abstract

Disclosed are a formaldehyde absorbing material and a preparing method thereof. The formaldehyde absorbing material comprises, by weight, 1 to 4 parts of glycerine, 0.2 to 0.8 part of antioxidant, 8 to 14 parts of polyacrylamide, 3 to 9 parts of silica, 15 to 25 parts of plastic powder, 35 to 45 parts of deionized water, 1 to 4 parts of ultraviolet absorbent, 1 to 5 parts of carbon fiber, 2 to 4 parts of preservative, and 12 to 18 parts of glass fiber. The preparing method includes mixing the polyacrylamide, the silica, the plastic powder, the carbon fiber and the glass fiber, putting mixture in a reactor, heating the reactor at 1000 to 1200 DEG C for 10 to 15 min to obtain first mixture; adding the glycerine, the antioxidant, the deionized water, the ultraviolet absorbent and the preservative into the first mixture, performing ultrasonic treatment after mixing to obtain second mixture, and extruding the second mixture in a double-screw extruder to obtain particle absorbing material, the formaldehyde absorbing material. The formaldehyde absorbing material is high in absorbing rate and helps effectively ensure physical health.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a formaldehyde absorbing material and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for living environment are getting higher and higher. Since indoor air pollution caused by wooden furniture and other materials is still very common, especially indoor formaldehyde pollution, it is the number one killer of human health, so simply opening windows for ventilation cannot solve the problem of formaldehyde pollution. [0003] Formaldehyde has a strong stimulating effect on the skin, eyes and respiratory tract, and has an anesthetic effect on the central nervous system. Formaldehyde coagulates proteins, is genotoxic to humans, and is also a mutagen. Activated carbon is often used as a formaldehyde absorption material, mainly through physical adsorption to reduce the c...
