Problems solved by technology

It is also ideal to add flame retardants to the filter material to improve the flame retardancy, but due to the limited impregnation amount of chemical substances, satisfactory ozone performance cannot be obtained
[0009] In addition, if the activated carbon layer does not contain thermoplastic resin adhesive particles, the activated carbon particles will not fall off during normal use, and the activated carbon particles will drip as a fire-igniting substance during the combustion test, so there is a problem that sufficient flame retardancy cannot be obtained.

Abstract

To provide an activated carbon sheet excellent in removability of hazardous gas component with ozonolysis function, and in flame retardancy. [Solution] A flame-retardant deodorizing filter containing an activated carbon bed with both surfaces thereof provided with fabric, the flame-retardant deodorizing filter having: the fiber ratio of the fabric that is one kind or more selected from at least cellulose fiber, polyvinyl alcohol fiber, polyacrylonitrile fiber and phenol fiber in 30% or more; the amount of phosphorus-based flame retardant in 10 to 70% by weight relative to the fabric weight; an adhesion layer between the activated carbon bed and the fabric; activated carbon particles adhered by thermoplastic resin binder particles; and the weight per unit area of activated carbon in 50 to 400 g / m2.

Description

technical field [0001] The invention relates to a flame-retardant deodorizing filter, which is installed in electronic equipment such as copiers, printers, multifunctional OA machines, electronic computers, projectors and POD printing machines, and is used to remove harmful gas components. The harmful gas components mentioned here do not include those harmful gas components that affect the human body and the environment, but also gases that cause internal failures in electronic equipment. Background technique [0002] In recent years, electronic equipment such as copiers, printers, multi-function OA machines, electronic computers, projectors, and POD printers have been further integrated and miniaturized, and in order to prevent heat from accumulating inside the equipment, heat dissipation through fans, etc. has gradually become impossible. be lacked. In addition, components used for typing, such as ink and toner, and various components contained in plastics constituting th...
