Compound catalytic material for purifying harmful gas

Abstract

The invention relates to a compound catalytic material for purifying harmful gas. Deionized water is used as dispersant to compound nano-catalytic material, rare earth compound, p-type semiconductor, antimicrobial, plant extract and anion powder. The compound catalytic material can fast and thoroughly eliminate free formaldehyde, benzene homologue, ammonia and TVOC harmful gas. The compound catalytic material does not require ultraviolet light, has simple use and low cost and does not have toxic side effect and secondary pollution, and the purification effect can last for more than five years without rebound. At the same time, the compound catalytic material prevents bacteria, germina and mildew from invading human body, removes peculiar smell, odor, smoke, leather flavour, paint flavour and the like, increases anion and far infrared ray which are beneficial to human body and improves indoor air environmental quality comprehensively. The experiment detection shows that formaldehyde clearance rate within 24 hours is 91.6 percent; benzene clearance rate is 88.9 percent; ammonia clearance rate is 90.5 percent; TVOC clearance rate is 87.6 percent; sterilization and bacteriostasis rate is 99.99 percent; mould prevention is 0 grade; and acute oral toxicity is tested as actually nontoxic class.

Description

Technical field [0001] The invention relates to a preparation method of a composite catalytic catalyst material for purifying harmful gases. Specifically, it relates to a method for removing formaldehyde and benzene released from indoors, vehicle interior decoration materials, decoration materials, furniture, floors, paints and adhesives. The preparation method of the composite catalytic purification catalyst material of system, ammonia, total volatile organic compound (TVOC) and antibacterial and antifungal, removal of peculiar smell, odor and harmful gas polluted by second-hand smoke. Background technique [0002] Since the 1970s, in western developed countries, people living and working in comfortable buildings are often plagued by unexplained illnesses, such as headaches, eye, nose and throat discomfort, dry cough, dry and itchy skin, dizziness and nausea, pay attention Difficulty with concentration and sensitivity to smells, etc., and these symptoms will disappear autom...

Problems solved by technology

However, since it is an electrical product, its long-term power consumption is also a problem to be considered

At the same time, the air circulation principle of its air purification is the same as the air conditioner, which is limited by the area. It is also very expensive to place a machine in each room
