Graphene paint mist treatment agent, preparation method and application method thereof

Abstract

A graphene painting mist treating agent comprises an A agent and a B agent; wherein the A agent is prepared from the following raw materials in percentage by weight: 0.02-0.08% of modified graphene, 1.6-2.6% of water-soluble melamino-formaldehyde resin, and 0.2-0.6% of sodium hydroxide; the B agent is prepared from the following raw materials in percentage by weight: 0.06-0.12% of water-based sodium bentonite, 0.2-0.5% of water-soluble acrylic resin, 5-10% of aluminium polychlorid and the balance of water. By using the graphene painting mist treating agent, adhesion of paint slag is completely eliminated, so that the paint slag is not adhered to a water screen or water curtain, air quality in a spraying room is increased, and no flying paint phenomenon exists in a factory; the paint slag completely flocculates and floats upwards, so that the paint slag is convenient and simple to fish out cleaning the bottom of a groove is not affected, and the cost for cleaning the groove is not increased; recycled water is clear and transparent; and the addition amount of drugs is small, so that costs are reduced and discharge is reduced.

Description

technical field [0001] The invention relates to a treatment agent in the field of industrial wastewater treatment, in particular to a graphene paint mist treatment agent used in the painting circulating water of a spray booth. Background technique [0002] If the equipment is exposed to the air or the external environment for a long time, it is prone to rust or other chemical reactions, causing damage to the equipment and affecting its service life and functions. Therefore, it is necessary to spray paint on the surface or wall of the equipment. During the air spray painting process, a large amount of paint mist and organic solvent gas are produced, which affects the health of the operator and seriously pollutes the surrounding environment and air. The painting system of the wind pressure-water washing spray booth has made a leap in the painting method, the painting quality has been greatly improved, and the pollution to the environment has been greatly reduced. At the same t...

Problems solved by technology

[0003] If the wind pressure-water washing spray booth does not use paint mist treatment agent, the paint entering the circulating water will not be debonded and condensed, and will adhere to the inside of the equipment, pipes and pump body, causing blockage of water and air passages, making The purification system is not functioning properly

At present, most of the treatment of paint slag in the circulating water of spray booths is the traditional paint mist treatment agent, such as the paint mist treatment agent composed of aluminosilicate colloid solution and poly N-dimethylaminoacrylamide aqueous solution, which is expensive , and the secondary pollution of circulating water is serious, the circulating water is turbid and prone to odor, and cannot be used for a long time. The frequency of circulating water replacement is high, resulting in waste of water resources and secondary pollution, which is not conducive to painting production

[0004] These traditional paint mist treatment agents also have the following disadvantages: for example, the paint slag cannot be completely debonded, and the paint slag adheres to the water curtain or the water curtain, causing the water curtain or the water curtain to be discontinuous, causing the paint mist molecules in the air to be effectively absorbed. Adsorption, and then cause "flying paint" phenomenon in the factory, destroying the quality of finished product coating

The paint slag of this invention cannot completely float to the water surface, and a small amount (about 5%) of the paint slag is suspended in the circulating water or sinks to the bottom of the water, causing the turbidity or transparency of the circulating water to fail to meet the standard
