Description

A kind of environment-friendly materials except formaldehyde

Technical field

This application involves the technical field of environmental protection more particularly to a kind of environment-friendly materials except formaldehyde.

Background technique

Since a large amount of ornament materials and new coating are applied to interior decoration, indoor toxic and harmful gas is caused to increase severely, It seriously affects the health of people, especially formaldehyde pollution and has always been considered as being the number one killer being detrimental to health, occupying In family's environment, if content of formaldehyde is exceeded, the health of human body will be directly influenced.The improvement of formaldehyde mainly uses currently on the market The method of physics or chemistry carries out, and physical method can only inhibit the volatilization of formaldehyde the short time, just ineffective for a long time；Mesh Preceding photocatalysis technology is mentioned the improvement applied to room air extensively, but since its excitation process needs higher ability, It needs to excite under ultraviolet light, limits its use, moreover, current product the asking there is also storage except formaldehyde Topic.Therefore, find it is a kind of can except the pernicious gases such as indoor formaldehyde again very friendly processing placement problem be very it is necessary to 's.

Utility model content

Preferably, the first TiO₂Layer with a thickness of 60-100nm.

Preferably, the 2nd SiO₂Layer with a thickness of 100-150nm.

Preferably, the 2nd TiO₂Layer with a thickness of 70-100nm.

Preferably, the substrate is glass, ceramics or organic glass.

Preferably, the substrate is glass.

Preferably, pattern layer is additionally provided between the substrate and the optical film layer.

Preferably, the sum of the optical film layer and the thickness of pattern layer are 400-600nm.

Preferably, the sum of the optical film layer and the thickness of pattern layer are 600-700nm.

This application provides a kind of environment-friendly materials except formaldehyde, comprising: substrate；The substrate is arranged in optical film layer Surface, optical film layer include the first SiO set gradually₂Layer, the first TiO₂Layer, the 2nd SiO₂Layer and the 2nd TiO₂Layer, and the One SiO₂Layer is connect with the surface of substrate.As can be seen from the above technical solutions, the embodiment of the present application has the advantage that this Shen Please except the material of the optical film layer of the environment-friendly materials of formaldehyde is the TiO being sequentially overlapped₂Layer and SiO₂Layer, without other pollution materials Material；Except outermost layer (the 2nd TiO of the environment-friendly materials of formaldehyde₂Layer) directly contacted with air, under sunlight or ultraviolet light, Pass through light-catalyzed reaction, the 2nd TiO₂Layer can be by the organic gas catalytic degradation of the harmfulnesses such as indoor formaldehyde at nontoxic gas Body, such as CO₂And H₂O。

Detailed description of the invention

In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, to embodiment or will show below There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this Some embodiments of application without any creative labor, may be used also for those of ordinary skill in the art To obtain other attached drawings according to these attached drawings.

Fig. 1 be the embodiment of the present application in provide except formaldehyde environment-friendly materials structural schematic diagram；

Appended drawing reference, substrate 1, the first SiO₂The 2, the first TiO of layer₂The 3, the 2nd SiO of layer₂Layer 4 and the 2nd TiO₂Layer 5.

Specific embodiment

This application discloses a kind of environment-friendly materials except formaldehyde, can effectively solve the existing product except formaldehyde, there is also deposit The technical issues of putting difficult and occupied space.

Referring to Fig. 1, a kind of specific embodiment of the environment-friendly materials except formaldehyde provided in the embodiment of the present application, packet It includes: substrate 1；Optical film layer, is arranged in the surface of substrate, and optical film layer includes the first SiO set gradually₂The 2, the first TiO of layer₂ The 3, the 2nd SiO of layer₂Layer 4 and the 2nd TiO₂Layer 5, and the first SiO₂Layer 2 is connect with the surface of substrate 1.

First SiO of the environment-friendly materials of the present embodiment₂Layer 2 and the surface of substrate 1 are connected and fixed, and outer layer is the 2nd TiO₂ Layer 5, can directly contact with air,

The present embodiment, preferably, the first SiO₂Layer with a thickness of 10-30nm；First TiO₂Layer with a thickness of 60- 100nm；2nd SiO₂Layer with a thickness of 100-150nm；2nd TiO₂Layer with a thickness of 70-100nm.

Wherein, the first SiO₂The 2, the first TiO of layer₂The 3, the 2nd SiO of layer₂Layer 4 and the 2nd TiO₂Layer 5, can pass through physical vapor Deposition method is arranged on substrate 1.
