specific Embodiment approach 1

[0014] Specific embodiment one: the non-photocatalytic air purifier at room temperature in this embodiment is made of 14 to 20 parts by weight of tourmaline, 2.5 to 3.7 parts of nano-titanium dioxide and 0.3 to 0.5 parts of palladium; wherein tourmaline, Both nano-titanium dioxide and palladium are in powder form.

[0015] In this embodiment, Pd is selected as the component of the catalyst, which not only reduces the product cost; but also breaks through the traditional TiO 2 The notion that supported Pd is less active for formaldehyde oxidation.

[0016] The room temperature non-photocatalytic air purifier of this embodiment is prepared according to the following method: Weigh the powdered tourmaline, nano-titanium dioxide and palladium according to the ratio of parts by weight, and then put the tourmaline, nano-titanium dioxide and palladium into a dry powder mixer to fully stir, That is, the room temperature non-photocatalytic air purifier of this embodiment is obtained. ...

specific Embodiment approach 2

[0021] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the particle size of tourmaline powder is 0.1-10.0 μm, the particle size of nano titanium dioxide is 5-100 nm, and the particle size of palladium is 0.1-10.0 μm. Other steps and parameters are the same as those in Embodiment 1.

[0022] A series of characterizations of the catalyst of this embodiment were carried out by BET specific surface area measurement method, X-ray diffraction (XRD), temperature programmed reduction (TPR), high-resolution transmission electron microscopy (HRTEM) and other means.

[0023] In the XRD spectrogram, there is no room temperature non-photocatalytic air cleaner of this embodiment (loaded Pd / TiO 2 Tourmaline) has a crystal phase peak of Pd, indicating that Pd is well dispersed on the surface of the carrier.

[0024] Although the carrier TiO can be clearly distinguished in the ultra-high resolution electron micrographs 2 and tourmaline lattice, but no particles ...

specific Embodiment approach 3

[0025] Specific implementation mode three: the formaldehyde-removing diatom ooze air-purifying coating of this embodiment is mainly composed of 14-20 parts of tourmaline, 2.5-3.7 parts of nano-titanium dioxide, 30-40 parts of diatomaceous earth and 0.3-20 parts by weight. Made from 0.5 parts palladium.

[0026] In this embodiment, the formaldehyde-removing diatom mud air-purifying paint is prepared according to the following method: Weigh powdered tourmaline, nano-titanium dioxide, diatomite and palladium according to the ratio of parts by weight, and then mix tourmaline, nano-titanium dioxide, diatomite and The palladium is put into a dry powder mixer and fully stirred to obtain the formaldehyde-removing diatom mud air-purifying coating of this embodiment.

[0027] The stirring time is generally about 30 minutes.

[0028] In this embodiment, the formaldehyde-removing diatom ooze air-purifying coating is added with diatomaceous earth, so it has excellent air permeability and ...

Abstract

The invention discloses a diatom ooze wall material applied to non-photo-catalysis purification of formaldehyde in air at room temperature, relates to a room-temperature air purification agent and a formaldehyde-removing air purification coating, which aims to solve the problems that the process of removing pollutants by catalytic oxidation at the room temperature at present can be realized under the light condition and the cost is high. A room-temperature non-photo-catalysis air purification agent is prepared from tourmaline, nano-titanium dioxide and palladium. A formaldehyde-removing diatom ooze air purification coating is mainly prepared from powdered tourmaline, nano-titanium dioxide, kieselguhr and palladium.

Description

technical field [0001] The invention relates to a room temperature air purifying agent and a formaldehyde-removing air purifying paint. Background technique [0002] Lung cancer, leukemia, infertility, fetal malformation, skin cancer, nose cancer, throat cancer and other diseases caused by indoor air pollution such as formaldehyde, benzene series, radon, ammonia, etc. have been common in recent years, and indoor decoration pollution is the main culprit. The global population morbidity and mortality caused by indoor air pollution are still rising, and it has been listed by the World Health Organization as one of the top ten threats to human health. The sampling survey conducted by the National Center for Disease Control and Prevention found that 70% of newly installed residential buildings in my country have decoration pollution, of which 60% formaldehyde exceeds the standard. [0003] Room temperature catalytic oxidation technology (Pt / TiO 2 Catalyst) has solved the proble...
