Writing board cleaning and maintaining solution and preparation method thereof

Abstract

The invention relates to a writing board cleaning and maintaining solution and a preparation method thereof, and belongs to the technical field of environment-friendly dust-free blackboards. The writing board cleaning and maintaining solution is prepared from the following components in percentage by mass: 1.5-6 percent of a fading dispersing agent, 0.02-0.07 percent of sodium sulfite, 0.02-1.5 percent of glucose, 0.03-0.9 percent of sodium thiosulfate, 0.02-0.06 percent of sodium borohydride, 0.25-0.6 percent of sodium carbonate, 0.01-0.15 percent of sodium bicarbonate, 0.03-0.05 percent of a complexing agent EDTA, and the balance of distilled water. The preparation method comprises the following steps: grinding solid substances: namely grinding the fading dispersing agent, sodium sulfite serving as a reducing agent, glucose, sodium thiosulfate, sodium borohydride, sodium carbonate and sodium bicarbonate, and screening through a 100-mesh screen; and preparing a finished product, namely sequentially dissolving the fading dispersing agent, sodium sulfite, glucose, sodium thiosulfate, sodium borohydride, sodium carbonate and sodium bicarbonate in distilled water under a stirring condition, adding the complexing agent EDTA, and stirring. The preparation method has the advantages of simple process and convenience in operation, and the writing board cleaning and maintaining solution has the advantages of stable product, no toxicity or odor, strong weather resistance, no writing liquid shadow, and the like.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and dust-free blackboard writing, in particular to a writing board cleaning care solution and a preparation method thereof. Background technique [0002] At present, the main components of traditional chalk are calcium sulfate, calcium carbonate, etc. A large amount of dust is generated during the writing and wiping process, which causes great harm to teachers and students, and the dust also seriously damages advanced multimedia teaching equipment. At present, The existing water-soluble chalk has no dust, but it needs to be wiped with water after writing, and the whiteness of the written handwriting is not enough, which seriously affects the students. Liquid blackboard writing liquid is the best way to solve the dust hazard. [0003] At present, liquid blackboard writing liquid products are generally made of pigments, dispersants, emulsifiers, lubricants, antifreezes, etc. after d...
