Problems solved by technology

[0003]With the popularization of smart blackboards, handwriting residues on the board surface are relatively serious and slight scratches are easy to appear during use. In the prior art, blackboard cleaning is generally used Cleaning liquid is used to maintain the smart blackboard, but after using the blackboard cleaning liquid, there are many residues on the board surface, which is inconvenient to use, and it only plays a cleaning role, and it cannot repair minor scratches
Since the value of the smart blackboard is relatively high, the overall replacement of the smart blackboard is not only costly, but also causes a waste of resources

Abstract

The invention discloses an intelligent blackboard repairing liquid, which comprises the following components by weight: 75-80 parts of ethanol; 10 to 15 parts of isopropanol; 5 to 10 parts of propylene glycol; 1 to 5 parts of polyvinyl butyral; and 5-10 parts of ethylene glycol diethyl caprylate. The invention further discloses a preparation method of the intelligent blackboard repairing liquid, and the preparation method comprises the following steps: adding the polyvinyl butyral into the triethylene glycol diethyl caprylate for first dispersion, then adding the ethanol and the isopropanol for second dispersion, finally adding the propylene glycol for third dispersion, and standing to obtain the intelligent blackboard repairing liquid. The invention further discloses the intelligent blackboard protection film and the intelligent blackboard. The coma blackboard repairing liquid can form a protective film on the surface of a panel, is convenient to use, effectively repairs slight scratches, reduces the friction force of the panel, and prolongs the service life of the panel.

Description

technical field [0001] The invention relates to the field of smart blackboard maintenance, in particular to a smart blackboard repair solution and a preparation method, a smart blackboard protective film and a smart blackboard. Background technique [0002] Smart Blackboard, also called Smart Blackboard, Nano Blackboard or Smart Classroom Interactive Blackboard, uses capacitive touch technology to combine traditional handwriting blackboards with multimedia devices, and can easily switch between chalk writing and multimedia applications. The smart blackboard does not take up extra space, and has the dual functions of blackboard and multimedia, so it is favored by more and more educational users. [0003] With the popularization of smart blackboards, the handwriting residue on the board surface is relatively severe and minor scars are likely to appear during use. In the prior art, a blackboard cleaning solution is generally used to maintain the smart blackboard. There are man...
