Problems solved by technology

[0004] Most of the debonding solutions with good debonding effect in the prior art are organic solvents (such as ethanol, acetone and sherwood oil, etc.), but their irritation and toxicity are relatively strong, which can easily cause operator's breathing discomfort, adhesion and irritation to the skin and damage to the skin. Defects that are unfavorable to health, the purpose of the present invention is to provide a JZ-NSMD001 organic solution, the solution is selected from trifluorotrichloroethane, 2,2,4,6,6-pentamethylheptane, 2,2, The five organic solutions of 7,7-tetramethyloctane, n-dodecane and ethanol are combined with each other in a certain proportion and have complementary characteristics to obtain a non-toxic, low-irritant and effect not lower than that of the prior art. Multi-component mixed debonding solution of viscous solution

Embodiment 1 and 2

[0025] In Examples 1 and 2 below:

[0026] The purity of trifluorotrichloroethane, 2,2,4,6,6-pentamethylheptane, 2,2,7,7-tetramethyloctane, n-dodecane and ethanol used are all commercially pure.

[0027] Relate to test as follows in the embodiment:

[0028] 1. Toxicity test——Shanghai Institute of Chemical Industry Testing Co., Ltd. issued a test report

[0029] The JZ-NSMD001 organic solution that embodiment makes is carried out toxicity test as follows:

[0030] (1) Acute oral toxicity test

[0031] The test was carried out according to GB / T 21603-2008 Chemical Acute Oral Toxicity Test Method. SD rats were used in the experiment. Before gavage, the experimental animals were fasted overnight. In the experiment, 20 animals (half male and half male) were infected with 5000mg / kg bw dose. After administration, observe and record the signs of poisoning and the death rate in the two-week observation period of the rats, and conduct autopsy observations.

[0032] (2) Acute inh...

Embodiment 1

[0047] Put 82mL of trifluorotrichloroethane, 1mL of 2,2,4,6,6-pentamethylheptane, 1mL of 2,2,7,7-tetramethyloctane, 1mL of n-dodecane and 15mL of ethanol into In a beaker, use a glass rod to stir and mix to prepare an organic solution of JZ-NSMD001.

[0048]The JZ-NSMD001 organic solution that the present embodiment makes is carried out toxicity test as follows:

[0049] (1) Acute oral toxicity test

[0050] Observe and record the rat's poisoning sign and the mortality rate (see Table 1 and Table 2) within the two-week observation period. During the test period, no animal death and poisoning sign were seen; no abnormality was observed in the autopsy. According to the test results, the acute oral toxicity LD of the test sample 50 Value >5000mg / kg (rat).
