Description
Technical Field
The invention relates to the technical field of paint of bioengineering, in particular to a method for generating negative ions by a nano carbonized plant modification and activation technology.
Background
In the house decoration process, as a plurality of adhesives, coatings and paints all contain formaldehyde, pollution gas mainly containing formaldehyde can be volatilized, and harm is caused to human bodies. The formaldehyde is determined as carcinogenic and teratogenic substances by the world health organization, and chronic respiratory diseases, pregnancy syndromes, leukemia and other diseases can be caused by long-term exposure to the formaldehyde, and chromosome abnormality of newborns, memory impairment of teenagers, mental retardation and the like can also be caused. Currently, the commonly used air purification technology is mainly physical adsorption, such as plant adsorption and activated carbon adsorption, wherein when activated carbon adsorption is used, activated carbon is mainly prevented from being adsorbed on a device with a certain structure by virtue of natural flow of air or the action of a fan, but because formaldehyde is slowly released for a long time, a formaldehyde removing device cannot be placed indoors all the time, and the formaldehyde can continuously cause harm to a human body. The coating is widely applied to decoration processes, but most of the existing coatings contain toxic and harmful substances and cannot ensure the health of the indoor environment. Substances such as benzene, dimethylbenzene, TVOC, PM2.5 and the like exist indoors, so that indoor air pollution is more than 5 times of outdoor air pollution, and the health of people is seriously influenced.
Disclosure of Invention
Aiming at the problems, the invention provides a method for generating negative ions by a nano carbonized plant modification and activation technology, the prepared negative ion powder is added into a coating, the concentration of the generated negative ions is higher, the average number of the negative ions released per cubic centimeter can reach more than 3000, harmful substances such as formaldehyde, benzene, dimethylbenzene, TVOC, PM2.5 and the like can be effectively degraded, the smell and the smoke are removed, the sterilization and the dust fall are realized, the air is freshened as in a forest, and the health of family members is durably and quickly cared.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a method for generating negative ions by a nano carbonized plant modified activation technology, which is characterized by comprising the following steps:
s1: removing roots of Malvaceae plant, cleaning, soaking in alcohol for 30 min, and cleaning with deionized water;
s2: cutting the plants into 2-3cm long sections, putting the long sections into a stirrer, filling an alkaline solution into the stirrer, heating the liquid in the stirrer to 165-180 ℃, continuously stirring for 2 hours, digesting the plants to generate a lignin-containing solution, sieving the liquid, and removing residual fibers to obtain the lignin-containing solution;
s3: adding hydrochloric acid into the lignin-containing solution obtained in the step S2 to adjust the pH value to be 5.5-6, adding an antioxidant and a processing modifier, continuing stirring for 10 minutes, adding a coagulant to extract a condensate, washing the extracted lignin condensate with water for multiple times to remove impurities, wherein the condensate contains plant crushed materials, the antioxidant and the processing modifier, and evaporating the condensate to remove water;
s4: putting the condensate obtained in the step S3 into a crusher to be scattered, then putting the crushed condensate into a carbonization furnace, maintaining the carbonization furnace in carbon dioxide or nitrogen atmosphere, controlling the carbonization temperature to be 80-120 ℃, and preserving the temperature for 30 minutes to form carbide;
s5: placing the carbide obtained in the step S4 into a grinding machine for coarse grinding for 1 hour to obtain particles with the particle size of 0.01-0.1 mm;
s6: putting the particles obtained in the step S5 into a high-temperature vacuum furnace, vacuumizing to 0.001pa, slowly heating to over 800 ℃, and preserving heat for 20 minutes for further carbonization;
s7: then putting the carbide obtained in the step S6 into a high-pressure airflow turbine crusher for heating and crushing for more than 1 hour to obtain particles with the particle size of 8-20 microns;
s8: transferring the carbide obtained in the step S6 to a high-pressure jet turbine pulverizer with higher precision for pulverization under positive pressure, introducing nitrogen into the pulverizer to avoid oxidation of particles during pulverization, and pulverizing for 1 hour to obtain particles of 10-400 nm;
s9: the particles obtained in step S8 are added to a paint formulation, and the paint has the property of generating negative ions.
Preferably, the antioxidant is selected from one or more of ethyl 3, 4-dihydroxybenzoate, tert-butyl p-hydroxyanisole and inositol phosphate.
Preferably, the processing modifier is selected from one or more of low molecular weight chlorinated polyethylene, acrylic acid and fatty alcohol modified polymers.
Preferably, the volume fraction of the alcohol in the step S1 is 5% to 30%, and the alcohol is methanol, ethanol or isopropanol.
