Abstract
The invention relates to the technical field of paint, in particular to an inorganic dry powder paint capable of releasing anions and a preparation method thereof, wherein the inorganic dry powder paint comprises the following raw materials in percentage by weight: 10-50% of cement, 35-40% of calcium carbonate, 15-20% of quartz sand, 10-15% of limestone, 1.5-2% of calcium sulfate whisker, 0.3-0.5% of bentonite, 0.05-0.1% of retarder, 1.5-2.0% of anion powder, 0.05-0.1% of catalyst, 0.05-0.1% of defoamer, 0.2-0.3% of magnesium aluminum silicate and 0.05-0.1% of vitrified micro bubble. Compared with the traditional organic powder coating, the inorganic dry powder coating is more environment-friendly, free of volatile VOC, gas-proof and flame-retardant, can release anions for a long time and is high in efficiency, and the inorganic dry powder coating can play a role in purifying indoor air; meanwhile, the amount of organic resin is reduced by adding a plurality of inorganic material powders, so that the cost of the coating is reduced.
Description
Technical Field
The invention relates to the technical field of coatings, in particular to an inorganic dry powder coating capable of releasing anions and a preparation method thereof.
Background
Along with the improvement of the living standard of people, the requirements on environmental protection of the environment, daily necessities and the like are higher and higher. The development of the coating industry also tends to be in the environment-friendly direction. Most people spend most of each day indoors, people pay more attention to the indoor air quality, and the first index for evaluating the indoor air quality is the content of negative ions; the negative ions can act on the mucosa of the upper respiratory tract of a human body, so that the secretion function of glands is improved; can improve pulmonary ventilation, and can increase oxygen inhalation and carbon dioxide discharge. After negative ions enter the blood, the oxygen carrying function of the blood flow can be improved, and the blood is purified; it also has effects in promoting metabolism, enhancing immunity, relieving fatigue, and recovering physical strength. Therefore, the anion paint is an advanced environment-friendly functional paint, has excellent performance, is green and ecological, has forest function, and is widely applied to the painting of the environments such as families, schools, hospitals, high-grade apartments, diet operation rooms and the like. The negative ions mainly realize the purpose of purifying air through the three functions of electricity, chemistry and physics, namely through the electric neutralization function, chemical reaction and physical adsorption, and have the effects of delaying aging, promoting blood circulation and metabolism, improving sleep, enhancing immunity, refreshing air and degerming and deodorizing.
Chinese patent application CN1011225278A discloses an anion powder coating capable of releasing anions effectively, but a large amount of organic resin is used therein, which not only results in too high use cost, but also has unstable chemical properties and poor wear and heat resistance effects; the paint has long time for drying the coating film when in use, thereby making the construction period longer; in addition, the paint has poor surface performance and adhesion.
Disclosure of Invention
In order to overcome the defects and shortcomings in the prior art, the invention aims to provide the inorganic dry powder coating capable of releasing anions, and compared with the traditional organic powder coating, the inorganic dry powder coating prepared by adopting the raw materials is more environment-friendly, free of volatile VOC, gas-proof and flame-retardant, can release anions for a long time and is efficient in antibacterial, and can play a role in purifying indoor air; meanwhile, by adding a plurality of inorganic material powders, the consumption of organic resin is reduced, the cost of the coating is reduced, and the prepared inorganic dry powder coating has stable chemical property, wear resistance, heat resistance, good surface property and adhesive force and can shorten the drying time of the coating film.
