Description

Preparation method of formaldehyde-removing curtain
Technical Field
The invention relates to the technical field of curtain preparation, in particular to a preparation method of a formaldehyde-removing curtain.
Background
In modern society, aldehydes substances generally exceed the standard after new houses are decorated. The aldehyde substance is a gas with strong pungent smell, has pungent smell, great harm to human body and long incubation period, and is called as a first killer of indoor pollution; aldehydes are also the leading causes of malformations in newborns, childhood leukemia, decline in memory and intelligence in adolescents and are identified by the world health organization as "carcinogenic and teratogenic substances". Therefore, the methods for removing aldehydes on the market are also of the fig. eight, and in general, can be divided into the following categories:
the first type: the porous material is physically adsorbed, such as activated carbon, bamboo charcoal, diatomite and the like, but the method cannot decompose aldehyde substances and only temporarily captures the aldehyde substances. When the room temperature rises and the adsorption is saturated, the aldehyde substances are released again to form secondary pollution.
The second type: green plants are cultivated indoors, and aldehyde substances are eliminated by utilizing the photosynthesis of the plants. In fact, the respiratory capacity of plants is rather limited, usually on the microgram scale. If aldehydes substances in a room exceed standards, thousands of pots of plants need to be placed, and a certain effect can be achieved by continuous illumination
In the third category: spraying aldehyde substance dissolving enzyme which can oxidize the aldehyde substance into acid or reduce the aldehyde substance into alcohol, but the toxicity of the product still exists, and the high-concentration scavenger generates new pollution harm to people when being sprayed in the air.
The fourth type: by applying the air purifier, under the condition that indoor air is polluted, the pollution degree can be reduced to a certain degree by using the air purifier, but the air purifier only plays a role in assistance and remediation and does not mean that air pollution can be fundamentally eliminated.
The fifth type: photocatalyst for decomposing aldehydes and core components thereofTypically nano titanium dioxide (TiO)2). However, since the forbidden band width of a general photocatalyst is large, the photocatalyst can only react under the excitation of ultraviolet light. Obviously, the photocatalyst hardly has any effect on indoor aldehyde removal, because most energy-saving lamps, fluorescent lamps and LED lamps hardly contain light in an ultraviolet band. For a photocatalyst that cannot perform a photocatalytic reaction in a visible light band (400 to 800 nm), even if its other index is good, the effect of protecting against harmful gases such as aldehydes is extremely limited. It is known that about 4% of sunlight is ultraviolet light, about 49% is visible light, and the rest is infrared light and far infrared light. If the photocatalyst is used for removing aldehyde indoors, the photocatalyst does not play any catalytic role unless an ultraviolet lamp is installed for irradiating the photocatalyst.
A non-light formaldehyde-removing catalyst is mentioned in the Chinese patent with the publication number of CN107185535B, which can be used for removing formaldehyde curtains, but if only the non-light formaldehyde-removing catalyst is used, the formaldehyde can be removed under the illumination condition in a waste manner, and the formaldehyde can be removed under the illumination condition more quickly. How to enable the curtain to remove formaldehyde under the condition of no light and quickly remove formaldehyde under the condition of illumination becomes a problem to be solved.
