Problems solved by technology

[0004] For the large amount of fume emitted by life and catering industry, the main treatment methods currently on the market are: mechanical separation, catalyst, combustion method, adsorption method, electrostatic treatment method, etc. Among them, the adsorption method has the advantages of low cost and operating cost , however, the composition of oil fume is complex, and the adsorption material of a single solid is difficult to achieve the effect of adsorption and purification
These treatment technologies are complicated in process and high in cost (the cost of adsorption method is slightly lower) and the components of oil fume are complex. They must be adsorbed and decomposed according to their physical and chemical characteristics, otherwise they will not only fail to purify, but even cause secondary pollution.

Abstract

The invention discloses a water-based composite adhesive sticker capable of purifying air. The water-based composite adhesive sticker comprises an A-type adhesive (adsorption adhesive) and a B-type adhesive (filter adhesive). The A-type adhesive is composed of 1-10% of sodium polyacrylate, 0.5-8% of CMC (sodium carboxymethyl cellulose), 1-6% of CMS (sodium carboxymethyl starch), 8-20% of urea, 4-9% of betaine, 10-30% of glycerol, 0.1-1.2% of silicon dioxide and 50-75% of water. The B-type adhesive comprises 0.5-6% of polyacrylamide, 2-8% of CMS, 10-21% of urea, 3-9% of betaine, 2-8% of polyethyleneglycol, 0.1-1.4% of silicon dioxide, 6-20% of glycerol and 50-75% of water. The invention also discloses a preparation method of the water-based composite adhesive sticker capable of purifying air. The method comprises the following steps: preparation of the A-type adhesive, and preparation of the B-type adhesive. The water-based composite adhesive sticker can lower the air pollution caused by oil fume and industrial and mining harmful gases, and is applicable to the field of air purification.

Description

Technical field [0001] The present invention relates to air purification, in particular to an aqueous composite adhesive for air purification and a preparation method thereof. Background technique [0002] The air, especially the air polluted by oil fume and industrial and mining hazardous gases in the city, contains a large number of tiny (less than or equal to 2.5μm) solid particles or droplets. The main ingredients are organic carbides, sulfates, nitrates, ammonium salts and sodium, magnesium, calcium, aluminum, iron and even lead, zinc, arsenic, cadmium and other elements. Due to the small particles and light weight, they can be suspended for a long time. In the air, long-distance drift and diffusion make the atmosphere contaminated. In the process of human breathing, these airborne particles larger than 5μm can enter the human airway and bronchus. Those smaller than 5μm can enter the alveoli, or even enter the blood, and follow the blood. Circulate to all parts of the human...
