Description

Formaldehyde purification plate

Technical Field

The utility model particularly relates to a formaldehyde purifies panel.

Background

Currently, the interior decoration sheet materials mainly include: laminated wood boards, plywood, decorative panels, density boards, laminated wood, shaving boards, fire-proof boards and the like, and a large amount of harmful gases such as formaldehyde exist in decorative boards used indoors such as paint, emulsion paint or adhesive. Studies have shown that the release period of formaldehyde in rooms is typically 3 to 15 years. The long-term life can bring very big injury to the human body in the space that contains harmful gas such as formaldehyde, and research shows: formaldehyde has strong carcinogenic and carcinogenic effects.

Therefore, a functional board capable of adsorbing and decomposing formaldehyde in the air is a health requirement of people and is a development direction of furniture boards.

Present panel for interior decoration, to getting rid of the panel because of the formaldehyde of building material giving off, people still mainly rely on ventilation to accelerate the volatilization of formaldehyde in the panel, but this process is slow, or with removing the formaldehyde device, reach the purpose that removes formaldehyde, for example chinese patent CN201920705088.5 patent is a panel processing apparatus for desorption formaldehyde, the external formaldehyde device structure that removes is complicated, the cost is higher, waste time and energy during the use, consequently, it is the direction of furniture panel development to provide the panel that can adsorb and decompose formaldehyde in the air.

Disclosure of Invention

The utility model discloses structurally improving at current panel, providing a panel with formaldehyde purification function, solving the problem that exists among the prior art.

In order to realize the above-mentioned purpose, the utility model provides a formaldehyde purification panel, including multilayer substrate and adhesive layer, the adhesive layer is used for the connection of adjacent basic unit, according to the constitution material difference of panel and take different technologies to glue, like hot pressing, pressfitting, curved type groove has all been opened on the upper and lower surface of basic unit, curved type inslot is filled there is porous alumina, it has the sodium chlorite bisque to adhere to on the porous alumina, be provided with a plurality of holes on the inner wall in curved type groove, unnecessary porous alumina can pack the hole closely knit when the substrate is glued, guarantee the intensity of panel.

Further, the porous alumina with the sodium chlorite powder layer is spherical.

Furthermore, the top surface in curved type groove sets up the filter screen, and the mesh aperture of filter screen is less than the diameter of porous alumina, and porous alumina is difficult for oozing during the veneer.

Further, the net layer is made of rattan net or bamboo net.

The utility model has the advantages that:

the utility model discloses simple structure, it is reasonable, utilize the function that current material increased panel, can effective absorption indoor formaldehyde after the use, indoor air-purifying is fit for mass production.

The reference numbers illustrate:

1. a substrate; 2. an adhesive layer; 3. a curved groove; 4. a hole; 5. porous alumina particles; 6. and (6) a mesh layer.

Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present invention, but not all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

Referring to fig. 1, fig. 2, the utility model provides a formaldehyde purification panel, including multilayer substrate 1 and adhesive layer 2, the adhesive layer is used for the connection of adjacent basic unit, the substrate is for using poplar, eucalyptus, wood shavings or the veneer that easy raw materials such as birch wood processed into, take different technologies to glue according to the substrate difference, like hot pressing, the pressfitting, curved type groove 3 has all been opened on the upper and lower surface of basic unit, curved type inslot packing has porous alumina granule 5, it has sodium chlorite bisque to adhere to on the porous alumina, be provided with a plurality of holes 4 on the inner wall in curved type groove, unnecessary porous alumina can pack the hole closely knit when the substrate is glued, guarantee the intensity of panel.

In the embodiment, the porous alumina with the sodium chlorite powder layer is a spheroid, and is prepared by the prior art, and an inorganic acid solution containing a surfactant is prepared to soak the porous alumina; putting sodium chlorite powder into a disc type granulator through a polyvinyl alcohol aqueous solution and porous alumina, and carrying out coating, granulation and drying to obtain the immobilized chlorine dioxide porous alumina particles with the particle size of 1-5 mm. When the particles are applied to the board, moisture or reducing substances in the environment are absorbed through the pores of the board, and the reaction of sodium chlorite and the water or the reducing substances is initiated to release chlorine dioxide gas, so that the effect of removing formaldehyde and purifying air is achieved.

The top surface of this embodiment curved groove sets up stratum reticulare 6, and the mesh aperture of stratum reticulare is less than the diameter of porous alumina, and porous alumina is difficult for oozing during the veneer.
