Problems solved by technology

[0003] The current way to deal with indoor formaldehyde is to place formaldehyde-removing plants indoors, such as Chlorophytum, Sansevieria, Ivy, Aloe, etc., but their absorption rate will be very low at night and in rainy weather; activated carbon adsorbents can also be placed indoors, but It needs to be replaced after it reaches a certain level, and it needs to be placed in different quantities according to the size of the room, so this method is more troublesome; you can also place an air purifier indoors, but it can only be used in a closed space if it is opened. Windows not only do not purify indoor formaldehyde, but also waste a lot of electricity; in addition, chemical agent purification method can also be used, but this method treats the symptoms but not the root cause, and only a small part of the diluted formaldehyde is absorbed or reflected. Generally speaking, these methods cannot remove indoor formaldehyde to a certain extent.

example 1

[0017] In a newly renovated room of 80 square meters, ordinary blue-green algae diatom mud was used to paint the walls. - After 5 days, the paint in the room was completely air-dried, and then in the room of the same area, the wall was painted with cyanobacteria diatom mud adsorption material added with active additives, and the formaldehyde in the two rooms was tested. The formaldehyde concentration of room 1 and room 2 with cyanobacteria diatom mud added with active additives is the same, the concentration is 0.64mg / m 2 After half a month, it will be tested again, and the formaldehyde concentration in Room 1 is 0.52mg / m 2 , the concentration of formaldehyde in Room 2 is 0.30mg / m 2 One month later, the indoor formaldehyde content was tested, and the formaldehyde concentration in Room 1 was 0.21mg / m 2 , the concentration of formaldehyde in room 2 is 0.06mg / m 2 Through comparison, it can be concluded that the cyanobacteria diatom mud added with active additives has a high re...

[0019] In a newly renovated room of 80 square meters, ordinary blue-green algae diatom mud was used to paint the walls. - After 5 days, the paint in the room was completely air-dried, and then in the room of the same area, the wall was painted with cyanobacteria diatom mud adsorption material added with active additives, and the formaldehyde in the two rooms was tested. Room 1 has the same formaldehyde concentration as room 2 with cyanobacteria diatom mud added with active additives, the concentration is 0.60mg / m 2 After half a month, it will be tested again, and the formaldehyde concentration in Room 1 is 0.42mg / m 2 , the concentration of formaldehyde in Room 2 is 0.25mg / m 2 One month later, the indoor formaldehyde content was tested, and the formaldehyde concentration in Room 1 was 0.19mg / m 2 , the concentration of formaldehyde in room 2 is 0.064mg / m 2 Through comparison, it can be concluded that the cyanobacteria diatom mud added with active additives has a high removal ...

[0021] In a newly renovated room of 80 square meters, ordinary blue-green algae diatom mud was used to paint the walls. - After 5 days, the paint in the room was completely air-dried, and then in the room of the same area, the wall was painted with cyanobacteria diatom mud adsorption material added with active additives, and the formaldehyde in the two rooms was tested. The formaldehyde concentration of room 1 and room 2 with cyanobacteria diatom mud added with active additives is the same, the concentration is 0.58mg / m 2 After half a month, it will be tested again, and the formaldehyde concentration in Room 1 is 0.39mg / m 2 , the concentration of formaldehyde in room 2 is 0.18mg / m 2 One month later, the indoor formaldehyde content was tested, and the formaldehyde concentration in room 1 was 0.10mg / m 2 , the concentration of formaldehyde in room 2 is 0.03mg / m 2 Through comparison, it can be concluded that the cyanobacteria diatom mud added with active additives has a high re...

Abstract

The invention relates to an active additive of a cyanobacteria and diatom ooze adsorption material, and belongs to the technical field of environment-friendly adsorption. The active additive is prepared from a low-VOC vinyl acetate-ethylene copolymer emulsion, silica sol, super absorbent resin and a phase-changed energy storage microcapsule, wherein the low-VOC vinyl acetate-ethylene copolymer emulsion and the silica sol are compounded to form a film-forming matter; the super absorbent resin is a moisture control packing; and the phase-changed energy storage microcapsule is a temperature control additive, and thus compound cyanobacteria and diatom ooze is prepared; the cyanobacteria and diatom ooze is painted on a wall as coating; and in comparison with a common compound cyanobacteria and diatom ooze coating, for the active additive of the cyanobacteria and diatom ooze adsorption material, disclosed by the invention, the formaldehyde removal rate is high, and reaches over 91%.

Description

technical field [0001] The invention relates to an active additive of cyanobacteria diatom mud adsorption material, which belongs to the technical field of environmental protection adsorption. Background technique [0002] While decoration makes the living room comfortable and beautiful, it also pollutes the indoor environment. This problem has attracted the attention of the world as early as the 1970s. Formaldehyde is a highly toxic substance, and it ranks second on the list of priority control of toxic chemicals in my country. Formaldehyde is defined as carcinogenic and teratogenic shape material by the World Health Organization, is the allergen of generally acknowledging, also is one of potential strong mutagen. Studies have shown that: formaldehyde has strong carcinogenic and short cancer effects. The lot of documents record, formaldehyde mainly shows aspects such as allotriosmia, stimulation, allergy, abnormal pulmonary function, dysfunction of liver and immunologic d...
