Embodiment 1

[0036] Add 10 parts by mass of N,N-dimethylaminoethyl methacrylate monomer to 0.12 parts by mass of initiator potassium persulfate to carry out monomer polymerization. The reaction temperature is 50° C. After 4 hours of reaction, a mixed solution is obtained; then 30 parts by mass of polyethylene glycol (the molecular weight of the polyethylene glycol is 2000, white solid waxy flakes, with good hydrophilic properties) is added to 150 parts by weight of water at 90 ° C and stirred to dissolve, and then the above mixed solution is dropped Mix evenly, then add 0.46 mass parts of sodium lauryl sulfate for mechanical stirring, the stirring rate is 300 rpm, and mix for 7 hours; after uniform mixing, pour it into a glass petri dish and slowly dry it under vacuum to form a film. After 24 hours of drying. A moisture-permeable degradable chemical warfare agent composite film was prepared. The thickness of the film was 1.0 mm. The moisture-permeable effects under different ambient humidi...

[0038] Add 30 parts by mass of N,N-dimethylaminoethyl methacrylate monomer to 0.15 parts by mass of initiator potassium persulfate to carry out monomer polymerization reaction at a temperature of 60°C, and react for 6 hours to obtain a mixed solution; then Add 23 parts by weight of polyethylene glycol (the molecular weight of the polyethylene glycol is 2000, white solid waxy flakes, with good hydrophilic properties) into 115 parts by weight of water at 90°C and stir to dissolve, then drop into the above mixing Mix the solution evenly, then add 0.2 sodium lauryl sulfate in mass parts for mechanical stirring, the stirring rate is 100 rpm, and mix for 8 hours; after uniform mixing, pour it into a glass petri dish and slowly dry it under vacuum to form a film , after drying for 12h. A moisture-permeable degradable chemical warfare agent composite film is prepared, and the thickness of the film is 0.07mm.

Embodiment 3

[0040] Add 60 parts by mass of N, N-dimethylaminoethyl methacrylate monomer to 0.2 parts by mass of initiator potassium persulfate to carry out monomer polymerization at a temperature of 70° C., and react for 8 hours to obtain a mixed solution; then Add 13 parts by mass of polyethylene glycol (the molecular weight of the polyethylene glycol is 2000, white solid waxy flakes, with good hydrophilic properties) into 65 parts by weight of water at 90°C and stir to dissolve, then drop into the above mixing Mix the solution evenly, then add 0.6 parts by mass of sodium lauryl sulfate for mechanical stirring, the stirring rate is 200 rpm, and mix for 7.5 hours; after uniform mixing, pour it into a glass petri dish and slowly dry it under vacuum. film, after drying for 18 h. A moisture-permeable degradable chemical warfare agent composite film was prepared, and the thickness of the film was 2.0mm.

Abstract

The invention relates to a moisture-penetrable degradation chemical warfare agent composite film and its preparation method and use. The preparation method comprises the following steps of adding 0.12 to 0.2 parts by mass of an initiator into 10 to 60 parts by mass of a 2-(dimethylamino)ethyl methacrylate monomer for a monomer polymerization reaction, dropwisely adding 13 to 30 parts by mass of polyethylene glycol into the reaction products, uniformly mixing, adding 0.2 to 0.6 parts by mass of sodium lauryl sulfate into the mixture, carrying out mechanical stirring until uniform mixing, pouring the mixture into a glass culture dish, and carrying out slow drying in vacuum to obtain the moisture-penetrable degradation chemical warfare agent composite film. Compared with the prior art, the moisture-penetrable degradation chemical warfare agent composite film contains a degradation chemical warfare agent and good moisture penetrability.

Description

technical field [0001] The invention belongs to the field of polymer functional composite materials, and in particular relates to a moisture-permeable degradable chemical warfare agent composite film, a preparation method and an application. Background technique [0002] In recent years, with the interweaving and intensification of multiple threats, the defense strategy of international defense organizations has transformed into chemical warfare agents, biological warfare agents, radioactivity, nuclear radiation and explosive protection. Chemical warfare agents are famous for their strong toxicity, wide lethality and difficult cure. Among the chemical warfare agents, the nerve agent sarin is highly toxic, stable in nature, quick to kill, and has no special color or smell. Until now, it is still the main poison in foreign military equipment, so it has become a research hotspot in various countries. [0003] Chemical warfare agent protective clothing is to protect people from...
