preparation example Construction

[0045] The present invention also proposes a method for preparing the novel self-adaptive camouflage paint as described above, including:

[0046] S1: Weigh the color-changing materials, film-forming substances, solvents, pigments and additives according to the mass ratio (1~10):(30~60):(10~15):(20~50):(2~10), High-speed grinding at a speed of 2000-3000r / min for 1-2 hours to obtain component A;

[0047]S2: Weigh component A, component B and solvent according to the mass ratio of 10:(1~10):(1~5), and disperse at a high speed of 800~1500r / min for 5~15min to obtain an adaptive camouflage paint .

[0048] The solvent weighed in step S1 and step S2 is the same solvent.

[0049] The preparation method of the novel self-adaptive camouflage paint provided by the present invention is simple in process and is suitable for mass production, and the prepared self-adaptive camouflage paint can be applied in the manufacture of military protection, functional fibers, fabrics and clothing. ...

Embodiment 1

[0053] This embodiment provides a novel self-adaptive camouflage paint, which includes A component and B component with a mass ratio of 10:1; the A component includes a mass ratio of 3:50:10:30: 7 orange-yellow discoloration material, two-component acrylic resin, DMF, green pigment and additives (dispersant, defoamer, leveling agent, UV aging additive, light stabilizer and antioxidant); the B group Divided into long-chain isocyanates.

[0054] This embodiment also provides a method for preparing the novel self-adaptive camouflage paint, including:

[0055] S1: Weigh the orange-yellow color-changing material, two-component acrylic resin, DMF, green pigment and additives according to the mass ratio of 3:50:10:30:7, and grind at a high speed of 2500r / min for 1.5h in a nano grinder , get A component;

[0056] S2: Weigh component A, component B and DMF at a mass ratio of 10:1:(3, and disperse at a high speed of 1200r / min for 5-15min to obtain an adaptive camouflage paint.

[005...

Embodiment 2

[0059] This embodiment provides a new type of adaptive camouflage paint. Compared with Embodiment 1, the color-changing material in the self-adaptive camouflage paint in this embodiment is replaced with khaki, and the pigment is replaced with white.

[0060] Add diluent to the self-adaptive camouflage paint prepared in this example to adjust its viscosity at 15-20 s (4-cup test), use a spray gun to spray on the surface of the metal plate, and heat to generate cross-linking reaction to obtain an self-adaptive camouflage coating. The adaptive camouflage coating spectrum such as figure 2 As shown, when the temperature is 20°C, the coating shows the khaki color of desert background; when the temperature is higher than 38°C, the coating shows snow white. It is worth noting that when the temperature is lower than 28 °C, the coating shows sky blue; when the temperature is higher than 28 °C, the color-changing material of sky blue color becomes colorless due to structural transformat...

Abstract

The invention discloses a novel self-adaptive camouflage coating as well as a preparation method and application thereof. The self-adaptive camouflage coating comprises a component A and a component B in a mass ratio of 10: (1-10), the component A comprises an off-color material, a film-forming substance, a solvent, a pigment and an auxiliary agent in a mass ratio of (1-10): (30-60): (10-15): (20-50): (2-10); and the component B is a curing agent. The preparation method comprises two steps, namely, preparation of the component A and preparation of the self-adaptive camouflage coating. According to the self-adaptive camouflage coating provided by the invention, the binding strength of the camouflage coating and a substrate can be greatly improved, and the fatigue resistance and environmental adaptability of the camouflage coating are enhanced; and the preparation method provided by the invention is simple in process and suitable for mass production, the prepared self-adaptive camouflage coating can be applied to manufacturing of military protection, functional fibers, fabrics and clothes, and the prepared camouflage coating is excellent in fatigue resistance and high in environmental adaptability.

Description

technical field [0001] The invention relates to the technical field of camouflage paint preparation, in particular to a novel self-adaptive camouflage paint and its preparation method and application. Background technique [0002] In recent years, with the rapid development of science and technology, camouflage coatings have been continuously introduced, with higher technical indicators and higher practical requirements. The traditional camouflage paint only has a single background camouflage, which obviously cannot meet the needs of future use. [0003] Adaptive camouflage paint is a new type of camouflage paint that can adapt to various backgrounds. It has strong adaptability and good stability, and is expected to become a new functional material. However, the existing self-adaptive camouflage paints have poor environmental adaptability. Contents of the invention [0004] The invention provides a novel self-adaptive camouflage paint and its preparation method and appli...
