Air purifying liquid and preparation method thereof

Abstract

The invention relates to an air purifying liquid and a preparation method thereof. The air purifying liquid comprises the raw materials in parts by weight: 1 to 50 parts by weight of glycerol, 1 to 15 parts by weight of polyethylene glycol, 0.5 to 5 parts by weight of dendrimers, 0.1 to 5 parts by weight of an imidazole cation liquid, 0.5 to 10 parts by weight of imidazolizone, 0.1 to 5 parts by weight of a pH regulator, and the balance deionized water. The preparation method comprises the steps: adding glycerol and polyethylene glycol into deionized water, and stirring until the solution is uniform and transparent; adding the dendrimers in the formed uniform and transparent solution, and stirring until the solution is uniform and transparent; adding the pH regulator to adjust the solution pH to 6.5-8.5, and stirring uniformly; and adding the imidazole cation liquid component and imidazolizone, and stirring uniformly, to obtain the purifying liquid finished product. The air purifying liquid is convenient to use: the air purifying liquid is injected into a spray bottle for operating, and is simple and convenient; the air purifying liquid is safe and reliable: the air purifying liquid is safe to human bodies and has no damage to objects; and the air purifying liquid has high purification efficiency: the air purifying liquid has the purification ability on formaldehyde and TVOCs more than or equal to 90%.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air purification liquid and a preparation method thereof. Background technique [0002] Spraying air purification liquid on indoor space and furniture, walls, floors, sofas, and cabinets can quickly remove pollutants in the air and provide a healthy living environment. At present, there are various air purification solutions mainly aimed at formaldehyde in the air. According to the mechanism of action, they mainly include: (1) oxidation type, the main components are similar to disinfectants, such as adding chlorine dioxide, sodium hypochlorite, sodium chlorite, etc. Oxidizing agent, using the strong oxidizing property of oxidizing agent to oxidize and remove formaldehyde. This type of purification solution has a strong oxidative safety problem, which may cause injury and damage to the human body, furniture and other utensils. (2) Photocatalytic type, which is obtain...

Problems solved by technology

This type of purification solution has a strong oxidative safety problem, which may cause harm and damage to the human body and furniture and other utensils

(2) Photocatalytic type, which is obtained by dispersing photocatalysts such as titanium dioxide in water. The advantage is good long-term effect; the disadvantage is that the purification speed is slow, and harmful intermediate products may be generated, and it will cause damage to furniture such as paint surfaces, etc.

(3) Adsorption type, which can quickly adsorb various pollutants, but due to the natural drying of the adsorbent in water after spraying, there are disadvantages such as poor adsorption capacity, desorption and release when the temperature rises or the concentration of pollutants decreases.

[0008] Currently commercially available air purification liquids have insufficient purifying ability, some have strong purifying ability to formaldehyde but weak to TVOCs purifying ability, and some have strong purifying ability to TVOCs but weak to formaldehyde purifying ability, so this field needs a kind of efficient Purification solution that can purify both formaldehyde and TVOCs, and the fixed pollutants can no longer be released
