Embodiment 1

[0058] The present embodiment provides a kind of coating method of 7-hydroxy bismethyl percarbon spiro coumarin, and the method comprises the following steps:

[0059] 2.0 mmol of 7-hydroxybismethyl all-carbon spiro coumarin compound, 30 mL of methanol and 1.0 mmol of MOF-808 were added to the reaction flask in sequence, and after stirring at room temperature for 3.0 h, suction filtration was performed with a filter funnel, and air was allowed to dry naturally. After drying, the coated product MOF-808@coumarin can be obtained.

[0060] In this example, the simulation simulation of the coating product MOF-808@coumarin was carried out, and its coating form was 1-7(7-hydroxybismethyl percarbon spirocoumarin)@MOF-808, and the coating simulation structure such as figure 1 shown.

[0061] from figure 2 It can be seen that the 7-hydroxybismethyl percarbon spirocoumarin in this example is obviously coated by MOF-808, and the coated product MOF-808@coumarin is obtained.

Embodiment 2

[0073] This embodiment provides a coating method of CL-20, such as Figure 4 As shown, the method includes the following steps:

[0074] Step 1, 7-hydroxybismethyl all-carbon spiro coumarin coating:

[0075] Adopt the coating method of 7-hydroxybismethyl percarbon spirocoumarin in Example 1.

[0076] Step 2, CL-20 coating:

[0077] Add 0.1 mmol melamine formaldehyde resin prepolymer to the reaction flask and dissolve it in 40 mL of toluene, then add 2.0 mmol CL-20, 1.0 mmol MOF-808@coumarin, mix evenly, add 3 drops of citric acid catalyst, and ultrasonically disperse evenly , the temperature was raised to 40° C. and stirred for 3.0 h to carry out in-situ polymerization (the process of coating reaction can also be detected by an ultraviolet lamp with a wavelength of 365 nm). After the coating is completed, suction filtration with a filter funnel, and air-dry to obtain a CL-20 coating product, such as Figure 5 shown.

Embodiment 3

[0080] The present embodiment provides an intuitive detection method for the coating uniformity of CL-20, which comprises the following steps:

[0081] Step 1, 7-hydroxybismethyl all-carbon spiro coumarin coating:

[0082] Adopt the coating method of 7-hydroxy bismethyl percarbon spiro coumarin in step 1 of embodiment 2.

[0083] Step 2, CL-20 coating:

[0084] Coating with CL-20 in step 2 of Example 2.

[0085] Step three, intuitive detection:

[0086] The coating product obtained in the second step is directly irradiated with an ultraviolet lamp with a wavelength of 365 nm, and the uniformity of the coating product can be visually detected through the solid-state fluorescence distribution.

[0087] The results of the intuitive detection are:

Abstract

The invention provides a visual detection method for CL-20 coating uniformity, which comprises the following steps: step 1, coating 7-hydroxyl dimethyl all-carbon spirocoumarin to obtain a coating product MOF-808-coumarin; step two, CL-20 coating: sequentially adding a melamine formaldehyde resin prepolymer, methylbenzene, CL-20 and the MOF-808 coumarin prepared in the step one, adding a citric acid catalyst, performing ultrasonic dispersion uniformly, stirring for in-situ polymerization, filtering, and naturally airing to obtain a coating product, namely a CL-20 coating product; and 3, visual detection: directly irradiating the coated product obtained in the step 2 by using an ultraviolet lamp so as to visually detect the uniformity of the coated product according to the solid-state fluorescence distribution condition. According to the visual detection method, after CL-20 coating is carried out, uniformity visual detection is carried out, the method is simple and convenient, and the efficiency of uniformity detection after CL-20 coating can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of energetic materials, relates to CL-20, and in particular relates to an intuitive detection method for the coating uniformity of CL-20. Background technique [0002] Coumarin compounds are widely found in Rutaceae and Umbelliferae plants and essential oils in nature, and are an important class of natural organic compounds. It has applications in medicine, fragrance, dye, instrument analysis, pesticide and other fields. In the field of medicine, coumarin and its derivatives have obvious biological activities, and have pharmacological properties such as hypoglycemic, anti-cancer, anti-virus, anti-inflammatory, anti-osteoporosis and antioxidant properties to the human body.
