Problems solved by technology

[0003] As desktop office supplies, solid glue sticks and correction fluids are in great demand, but their functions are relatively single
In particular, the correction fluid has the following disadvantages during use: 1) Since most of the correction fluid is in a liquid state, it is difficult to control the amount of liquid that flows out during use, so it is easy to smear off the parts that should not be corrected; 2) The powder in the correction fluid It is easy to reunite, and it needs to be shaken repeatedly before each use; 3) It will leak when it is not carried carelessly, which is inconvenient to use; 4) It contains a lot of organic solvents, which will have a negative impact on human health
In addition, the preparation of traditional solid glue sticks and correction fluids will generate a lot of waste, which will cause some pollution to the environment

preparation example Construction

[0015] figure 1 It is a process step diagram of a solid glue stick preparation method that can correct text in an embodiment of the present invention; the solid glue stick uses polyvinyl formal glue as a film-forming agent and adhesive, and is added by adding excipient stearic acid and moisturizing agent glycerin It is prepared with titanium dioxide as a covering agent, and the preparation method includes the following steps: a) preparing polyvinyl formal glue, b) feeding and mixing treatment, and c) filling and molding.

[0016] The text-correctable solid glue stick mentioned in the present invention integrates the functions of text correction and paper bonding. It is in the shape of a white solid and can be placed in a lipstick container. If it is used as a correction product, the glue stick unscrewed from the container base can be applied to the graphic to be modified, and it can be rewritten after drying; if it is used as an adhesive product, its usage is the same as the t...

Embodiment

[0018] The specific preparation method is as follows:

[0019] a) To prepare polyvinyl formal glue, the specific preparation process is as follows: First, take a certain amount of polyvinyl alcohol and deionized water in a mass ratio of 1:10 and add them to a reaction kettle placed in a water bath, and heat up in the water bath while stirring to 90°C, stir at constant temperature for 1 hour; then cool down to 85°C in a water bath, adjust the pH value of the solution to 3 with an appropriate amount of hydrochloric acid, and then add 25% formaldehyde according to the mass percentage of the amount of polyvinyl alcohol, and keep it warm for 1 hour to obtain polyvinyl alcohol. Vinyl formal glue; finally, the temperature of the water bath is lowered to 80°C, and the pH value of the solution is adjusted to 8 with a 30% sodium hydroxide solution, and 20% modifier urea is added according to the mass percentage of the polyvinyl formal glue , heat preservation reaction for 30 minutes, an...
