It is necessary to use a building material that does not contain VOCs or remove VOCs after construction. As a method for removing VOCs after construction, a bake out method is conventionally known. The bake-out method is a method for intermittently eliminating VOCs in a short period of time. The room temperature is reduced to around 40 ° C in a state in which a room (room) in a building (house, building, etc.) is normally closed (unmanned). This is a method of raising the temperature and holding it for a certain period of time to promote the emission of VOCs, and then ventilating and exhausting the windows by opening windows or a blower. Another method is to place a deodorant such as activated carbon in a room.

In addition, a heating device is required, and the bake-out process is troublesome. Further, it is difficult to remove and decompose VOCs effectively by a method of disposing a deodorant such as activated carbon in a room. SUMMARY OF THE INVENTION An object of the present invention is to provide a covering sheet that does not require a special device such as a heating device and can adsorb and decompose VOCs existing in an indoor environment.

A sheet-like environmental purification material was obtained. The coating amount of particles (manganese dioxide, cupric oxide, activated carbon and polyethylene particles) per unit weight of this sheet was 56% by weight.
