Detailed Description

In order that the objects and advantages of the invention will be more clearly understood, the invention is further described in detail below with reference to examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the following embodiments, a rag wiping manner is adopted to treat the double-sided adhesive (length 3.0cm and width 0.8cm) remaining on the plastic, metal, glass and wood substrate, and the adhesive removing effect of the cleaning agent is determined according to the time for just removing the residual adhesive on the double-sided adhesive on various substrates. In order to reduce the test error, the dosage of each reagent is kept the same, and a plurality of parallel tests are carried out, so that the test error caused by human factors is reduced as much as possible.

Example 1

The orthogonal test is optimized by designing formulas, and the orthogonal test result is calculated according to the glue removing time of each formula and is shown in table 1.

Table 1 formulation optimization orthogonal test and results calculation

Obviously, the mass fraction of the organic solvent is a significant influence factor, the ratio of the surfactant to the auxiliary agent also has a certain influence on the degumming time, and the ratio of the organic solvent can be determined to be 25% according to the degumming time, so that the ratio of the surfactant to the auxiliary agent is further determined on the basis.

Example 2

On the basis of orthogonal test, four formulas are screened out, weighed according to 100 g of standard formula, and tested for the adhesive removing effect of the following four formulas on four substrates of plastic, metal, glass and wood by taking adhesive sticker as an example, and the results are shown in the following table 2.

TABLE 2 Degumming effect test of formula

In summary, the following steps: 2. the samples No. 3 and 4 can well remove the residual glue, so a further comparison test is needed.

Example 3

No. 1 formula is removed, the other 3 formula samples and the solvent are used for a glue removal comparison test, a double-sided adhesive tape is taken as an example, and the test results are shown in a table 3.

TABLE 3 comparative test with conventional solvents

The test results are combined: the ethanol has high volatility, so that residual glue is volatilized before being dissolved and cannot be removed, and the smell of the ethanol is high; although the N-methyl-2-pyrrolidone, the ethyl acetate and the acetone can better remove the residual glue, the complete removal of the glue by using a solvent has the disadvantages of large smell, toxicity, flammability and the like, and is unsafe and environmentally-friendly; compare 2, 3, No. 4 samples can all totally thoroughly be got rid of to the double faced adhesive tape totally, and consuming time is shorter relatively, does not have obvious glue mark to remain. Therefore, sample No. 4 was determined to be the optimal formulation.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be construed as the protection scope of the present invention.
