Problems solved by technology

[0004] For the energetic materials used above, whether it is conventional casting, compression stretching process, or 3D printing process, the energetic materials prepared are all three-dimensional materials with a predetermined shape. After being excited, it can only burn or explode in a predetermined way, without the characteristics of environmental perception and response, and it is difficult to adapt to the complex and ever-changing combat environment.

Embodiment 1

[0034] The formula of this example is as follows: 70 parts of polyurethane acrylic resin; 30 parts of epoxy acrylic resin; 34 parts of 1,6-hexanediol diacrylate; 2,4,6-trimethylbenzoyl-ethoxy- 6 parts of phenyl phosphorus oxide; 45 parts of polycaprolactone (molecular weight 65000-80000); 550 parts of RDX (particle size 0.2-40 μm); 50 parts of nitroglycerin; 6 parts of graphene.

[0035] The preparation step is to set the temperature above the melting point of the crystalline polymer, which is 70° C. in this example, and mix all the components with a stirrer in the dark for 3 hours at a rotational speed of 200 rpm.

Embodiment 2

[0039] Different from Example 1, the formula of this example is as follows: 100 parts of epoxy acrylic resin; 50 parts of ethoxylated oxyphenyl acrylate; 2,4,6-trimethylbenzoylphenylphosphonic acid ethyl 10 parts of ester; 40 parts of polydecyl adipate (molecular weight: 30,000-40,000); 650 parts of HMX crystals (particle size: 0.2-40 μm); and 6 parts of carbon nanotubes.

[0040] The difference between the preparation process and Example 1 is that the mixing temperature is set to 85°C.

Embodiment 3

[0044] Different from Example 1, the formula of this example is as follows: 100 parts of polyether acrylate; 20 parts of trimethylolpropane triacrylate; 2-hydroxy-2-methyl-phenylacetone-1,1- 6 parts of hydroxy-cyclohexyl benzophenone; 20 parts of polyhexamethylene sebacate (molecular weight 30,000-40,000); 500 parts of CL-20 crystals (particle size 0.2-40 μm); 2 parts of iron tetroxide.

[0045] The difference between the preparation process and Example 1 is that the mixing temperature is set to 85°C.

Abstract

The invention provides a photocuring intelligent energetic material and a preparation method thereof. The disclosed formulation includes an acrylic resin, a reactive diluent, a photoinitiator, a crystalline polymer, an energetic solid oxidant, and a stimuli-responsive additive. The preparation method disclosed by the invention comprises the step of heating, melting and mixing all the components. The self-deformation of the energetic material under the stimulation of heat, electricity and magnetic fields is realized by utilizing the flexibility of the photosensitive resin and the melting-crystallization transformation of the crystalline polymer.

Description

technical field [0001] The invention relates to a light-cured intelligent energetic material, in particular to an energetic material suitable for a 3D printing process that can be deformed autonomously under the stimulation of temperature, humidity, electric field, magnetic field and the like. Background technique [0002] Energetic materials are a class of compounds or mixtures containing explosive groups or oxidants and combustibles, which can independently undergo chemical reactions and output energy. They are an important part of the formulation of military explosives, propellants and rocket propellants. Energetic materials can be divided into explosives, explosives, propellants and propellants according to the direction of use. At present, the manufacturing technologies of energetic materials used in military enterprises mainly include casting, extrusion, casting and new 3D printing technology. The prepared energetic materials with specific three-dimensional structures ...
