specific Embodiment approach 1

[0012] Specific embodiment one: The diatom ooze material of this embodiment non-glue type non-photocatalytic purification formaldehyde in the air consists of 35~45 parts of diatomite, 8~12 parts of brucite powder, 4~ 6 parts of illite powder, 4-6 parts of attapulgite, 4-6 parts of hydroxypropyl methylcellulose, 13-17 parts of starch, 4-6 parts of opal stone powder, 8-12 parts of lanthanum It is made of element oxide powder and 4-6 parts of nano silicon dioxide.

[0013] In this embodiment, the preparation method of the diatom ooze material for the non-photocatalytic purification of formaldehyde in the air without glue: Weigh diatomite, brucite powder, illite powder, attapulgite, and hydroxypropyl methylate according to the weight and number ratio. base cellulose, starch, opal stone powder, lanthanide oxide powder and nano silicon dioxide, then put the opal stone powder, lanthanide oxide powder and nano silicon dioxide into a dry powder mixer and stir at a high speed to obtain ...

specific Embodiment approach 2

[0016] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the diatom ooze material of the non-photocatalytic purification air formaldehyde in this embodiment is made of 40 parts of diatomite, 10 parts by weight. 4 parts of brucite powder, 5 parts of illite powder, 5 parts of attapulgite, 5 parts of hydroxypropyl methylcellulose, 15 parts of starch, 5 parts of opal stone powder, 10 parts of lanthanide oxide It is made of material powder and 5 parts of nano-silica.

specific Embodiment approach 3

[0017] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the diatomite wall material also includes 4 to 6 parts of nano rhodochrosite powder and 4 to 6 parts of nanometer rhodochrosite powder in parts by weight. copper. Other steps and parameters are the same as those in Embodiment 1 or 2.

[0018] This embodiment can accelerate the decomposition of formaldehyde.

Abstract

The invention provides an adhesive-free non-photocatalytic diatom ooze material for removing gaseous formaldehyde in air and relates to a diatomite wall material capable of purifying air. The existing problems that a diatomite coating added with a chemical adhesive is hardened and solidified and loses original filtration and absorption functions and that chemical adhesive-free diatomite is poor in adhesiveness and has such serious problems as dusting and peeling off after moisturizing are solved. The diatomite wall material is mainly prepared from diatomite, starch, lanthanide oxide and opal in parts by weight. The adhesive-free non-photocatalytic diatom ooze material for removing gaseous formaldehyde in air in the invention is chemical adhesive-free and thus harmless to human body, and achieves true green and environmental protection.

Description

technical field [0001] The invention relates to a diatomite wall material capable of purifying air. 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, and 60% of them are formaldehyde exceeding the standard. [0003] Diatomite with adsorption is regarded as an important way to solve indoor decoration pollution; moreover, the special...
